Description

The The invention relates to a die-casting mold for the production of a Henkel and a Fußringwulst possessing crockery such as cups, sauceboats or the like, with an upper mold part, a lower mold part and two mold side parts, in the contracted state corresponding to the harness part Determine mold cavity, wherein a Schlickereingusskanal opens into the mold cavity.

at Such a die casting mold forms the lower mold part a core part and the form top a footboard.

From the DE 10 2005 036 906 A1 The applicant is a die-casting mold for the production of tableware, such as cups, cups or the like known having a mold top, a mold bottom and mold side parts. In order to achieve optimum rinsing properties for detaching the dish blank from the mold parts of the die, the lower mold part is formed with a rinsing cavity, which has an inner contour which is at least approximately adapted to the shape contour of the lower mold part. The molded parts consist of a porous plastic material, so that an at least approximately constant wall thickness results between the shape contour of the mold base and the inner contour of the rinsing cavity of the mold base, resulting from the optimum rinsing properties of the mold base. The mold side parts, each having a rinsing cavity with an inner contour adapted to the shape contour of the respective mold side part, can also be designed in correspondence with the mold bottom forming a core part. If appropriate, the same may also apply to the upper part forming a foot part.

The DE 10 2005 036 907 A1 the applicant describes a die-casting mold for the production of tableware, such as cups, cups o. The like., Which has a mold top, a mold bottom and mold side parts. The mold part forming a core part of the die casting mold is provided with a ring seal on its sealing surface assigned to the mold side parts. Likewise, the upper mold part may be provided with a second annular seal on its sealing surface associated with the mold side parts, so that a direct contact of the mold parts is avoided.

at the production of a handle possessing crockery parts it is generally difficult to use relatively thick-walled handle attachments Completely to fill with slip. The slip remains in these relatively thick-walled attachment points liquid inside, which is undesirable visible indentations leads. These are liquid inside Reinforce areas with increasing distance from the gate. This distance is especially great then when the slip-sprue through the upper part forming a form part to the foot ring bead takes place.

to solution this problem of the relatively large Distance between the handle attachment point and die casting site have already been proposed die casting molds, the Schlickereingusskanal by a Formseitenteil close to a handle attachment point to lead. In this known solution However, the demolding of the utensil blank is problematic, because during demoulding, first the upper part forming a foot part Will get removed. Subsequently drive the mold side parts apart. Because the solidified slip in Schlickereingusskanal yet with the coming from one side Slurry is connected in the adjacent to the Henkel attachment point Eingusskanalabschnitt is damage at the filling station of the Dishes or barely avoidable at the handle attachment point or it can Schlickerreste remain in the mold, which leads to disruptions in the production process to lead can. As a result of these problems, this last-mentioned slip-pouring variant is no longer used.

Of the In the knowledge of these circumstances, the invention is based on the object to provide a die of the type mentioned, with which it's easy and reliable possible is a handle and a foot ring bead owning tableware parts, such as cups, sauce boats o. The like., Reliable and with high productivity manufacture.

These The object is achieved by the Features of claim 1, d. H. solved by the fact that the upper mold part with one formed by its underside protruding Eingußnase is and the side parts at their mutually facing end faces respectively formed with a recess adapted to the Eingußnase are, and that the Schlickereingusskanal through the Formoberteil and extending through the sprue to a nasal drain hole and at the foot ring bead facing Henkel attachment point opens into the mold cavity, wherein the side parts at their facing end faces with Channel channels are formed in the contracted state the molded parts form a Henkelkanalabschnitt extending from the Nasenausgussloch extends to the Henkel attachment site.

Due to the inventive design of the die with the extending through the upper mold section Schlickereingusskanal, which opens at the handle attachment point in the mold cavity, there is the advantage that the Schlickereingusskanal has no distance with respect to the Henkel attachment point, so ver in an advantageous manner Prevents the slurry at the Henkel attachment point remains liquid inside and thus unwanted, visible indentations are prevented. In addition, it is prevented by the formation of the invention that the slip-filling point is damaged on the harness blank when opening the die-casting mold. The solid mass in the slurry feed channel can be safely rinsed off when opening the mold side members due to drainage holes that act directly on the slurry feed channel. If the slip-pouring channel came from the side, as has been described above with reference to the state of the art, no drainage holes could be provided in the case of a forming side part, since the pouring tube would be in the way. With the said advantage of avoiding damage, there is the further advantage that slip residues in the die casting mold, which lead to disruptions in the production process, are avoided.

Of the Schlickereingusskanal can in the associated Eingußnase total aslant be provided oriented. Likewise, it is possible for the slurry feed channel is formed angled in the Eingußnase, wherein the Nasenausgussloch on a tapering down Inclined surface of the Eingußnase is provided. By such a design results itself the advantage that when opening the die casting mold, d. H. when removing the foot part forming Form top of the still merging side panels, the in the Henkelkanalabschnitt the mold side parts located slip easy and reliable is separated from the slurry located in the nose portion. When opening the die casting mold, d. H. when removing the foot part forming Formoberteil is thus the slip compound on Schlickerausgussloch the nose part separated. The dishware blank is sitting here still firmly in the die, d. H. forming on the one core part Molded bottom and is of the still merging side panels held. In the subsequent Moving apart of the side parts can then be the solid, on the harness blank adhering residual slip of the two form side parts are cleanly detached. additionally can on these places drainage holes be provided, the dissolving assist the solidified slip in an advantageous manner.

One Another advantage of the pressure die according to the invention is that the foot area of the Crockery blank without visible sprues remains clean. Such sprues tend to grow out and are therefore often as defects scored.

Advantageous it is when the adjoining the Nasenausgussloch nostril channel section of Schlickereingusskanales tapered to Nasenausgussloch out is to the Schlickereingusskanal with a relatively large clear Cross section and the nose hole with a correspondingly small dimensioning clear cross-section, wherein the Nasenausgussloch then when opening the die casting mold, d. H. when removing the top mold the Abscherstelle for the solidified slip forms.

Of the Henkelkanalabschnitt in the mutually facing end faces of Side parts has expediently a cross-section of the cross-section of the Nasenausgussloches the pouring nose of the upper mold is adapted. The same is true it is useful if the nose-gutter-channel portion of the slurry-pouring channel and the Henkelkanalabschnitt the side parts with each other axially aligned.

Further Details, features and advantages will be apparent from the following Description of an embodiment shown in the drawing the die casting mold according to the invention.

For this purpose, the upper mold is 18 with from its bottom 28 protruding gates 30 trained and are the form side parts 20 on their mutually facing end faces 32 each with a to the associated Eingussnase 30 adapted recess 34 (please refer 2 ) educated.

The respective slip pouring channel 26 extends through the upper mold 18 and through the associated pouring nose 30 up to a nose hole 36 , The respective slip pouring channel 26 flows at the foot ring bulge 14 of the respective dishes 16 facing handle attachment point 38 in the corresponding mold cavity 24 one, with the two side panels 20 on their faces 32 with gutters 40 are formed, in the contracted state of the moldings 18 . 20 and 22 a Henkelkanalabschnitt 42 form, extending from the nose-hole 36 to the handle attachment point 38 extends. ( 1 and 3 )

The respective slip pouring channel 26 is in the corresponding pouring nose 30 of the mold shell 18 formed angled, with the Nasenausgussloch 36 on a downwardly tapered inclined surface 44 the respective pouring nose 30 is provided. The at the Nasenausgussloch 36 subsequent nostril canal section 46 the respective Schlickereingusskanales 26 is to the nose hole 36 formed tapered. ( 1 )

The handle channel section 42 the molded side parts 20 the handle shape of the respective ceramic article is oriented accordingly and expediently has a cross-section which corresponds to the cross section of the associated Nasenausgussloches 30 the respective pouring nose 30 is adjusted. The nostril canal section 46 the respective Schlickereingusskanales 46 and the handle channel section 42 the molded side parts 20 aligned with each other axially.

After Schlickergießen, ie the complete filling of the respective mold cavity 24 with the slip, after the end of the cullet forming time, the top mold becomes 18 from the form side parts 20 away. In this case, the junction of the formed cullet at Nasenausgussloch 36 disconnected. After the subsequent moving apart of the mold side parts 20 may be the cullet portion of Henkelkanalabschnittes 42 be removed from the respective harness blank. Subsequently, the harness blank from the mold base 22 decreased. This can be done manually or automatically.

Advantageously, it is in the die casting mold according to the invention 10 possible that the mold side parts 20 and the mold bottom 22 in the contracted state of the die 10 are not positively connected with each other, but that between the form side parts 20 and the mold bottom 22 a mechanical clearance in the form of a gap is present.
