Description
Ji Intraoperative field
The utility model relates to a kind of mould structure, particularly relates to a kind of treatment product band overhead kick mould structure.
Bei Jing Ji Intraoperative
In the prior art, mould is to the demoulding of product, usually use liftout attachments such as taper pin, thimble, after the mould die sinking, directly product is ejected down die, for example: a kind of mould structure, comprise a lower bolster, the one following die that holds formed product is set in the lower bolster, and a face of lower bolster is provided with a supporting with it cope match-plate pattern, and corresponding die down is provided with a upper cores in this cope match-plate pattern; Connect successively on the another side of above-mentioned lower bolster ejector retainner plate and ejector retainner plate once are set on one, on the following ejector retainner plate some thimbles are set, these thimbles pass ejector retainner plate, lower bolster successively, enter into down in the die, play the function that ejects product in the die sinking process.
When overhead kick appears in product, the mould of this kind structure, limited by overhead kick, can not finish and eject action, need to increase the device of slide block or other assistance moulding, but to the processing of some special overhead kicks, then need to design special mould structure, more can finish the entire product forming process easily and efficiently.
Summary of the invention
For addressing the above problem, the utility model proposes the special overhead kick mould structure of a kind of treatment product band.
The technical solution of the utility model is: a kind of mould structure, and it comprises a lower bolster, and a following die that holds formed product is set in the lower bolster, and a face of lower bolster is provided with a supporting with it cope match-plate pattern, and corresponding die down is provided with a upper cores in this cope match-plate pattern; Connect successively on the another side of above-mentioned lower bolster ejector retainner plate and ejector retainner plate once are set on one, on the following ejector retainner plate some thimbles are set, these thimbles pass ejector retainner plate, lower bolster successively, enter into down in the die, play the function that ejects product in the die sinking process; Wherein, at the corresponding surface of above-mentioned ejector retainner plate down with last ejector retainner plate joint face, connection one the 3rd ejector retainner plate is set, this 3rd ejector retainner plate is provided with a liftout attachment, in the die, play the product effect that ejects under this liftout attachment passes down ejector retainner plate successively, upward ejector retainner plate, lower bolster arrive.
The end that above-mentioned liftout attachment enters down die is provided with an angled slide block, and it is used to assist product overhead kick moulding and increases the area that liftout attachment contacts with product, leaves a trace when avoiding ejecting.
On above-mentioned ejector retainner plate, between ejector retainner plate and the 3rd ejector retainner plate shutter is set down, the three is united one, when needing, the three can be separated, perhaps separately some separately.
The utility model mould structure, when die sinking, shutter will be gone up ejector retainner plate, following ejector retainner plate and the 3rd ejector retainner plate locking one, at first, last ejector retainner plate, following ejector retainner plate and the 3rd ejector retainner plate move together, with the whole die that ejects down of product, after product and following die break away from, shutter is decontroled the 3rd ejector retainner plate, the 3rd ejector retainner plate stop motion, last ejector retainner plate and following ejector retainner plate drive thimble, and the product overhead kick is ejected from the angled slide block of assisting moulding, make product break away from constraint fully, finish die sinking.
Description of drawings
Fig. 1 mould structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
As shown in Figure 1, a kind of mould structure, it comprises a lower bolster 10, and a following die 100 that holds formed product is set in the lower bolster 10, a face of lower bolster 10 is provided with a supporting with it cope match-plate pattern 11, and corresponding die 100 down is provided with a upper cores 110 in this cope match-plate pattern 11; Connect successively on the another side of above-mentioned lower bolster 10 ejector retainner plate 12 and ejector retainner plate 13 once are set on one, ten thimbles 130 (can only see one among the figure) are set on the following ejector retainner plate 13, these thimbles 130 pass ejector retainner plate 12, lower bolster 10 successively, enter into down in the die 100, in the die sinking process, play the function that ejects product; Wherein, at the corresponding surface of above-mentioned ejector retainner plate 13 down with last ejector retainner plate 12 joint faces, be provided with and connect one the 3rd ejector retainner plate 14, this the 3rd ejector retainner plate 14 is provided with a push rod 140, in the die 100, play the product effect that ejects under this push rod 140 passes down ejector retainner plate 13 successively, upward ejector retainner plate 12, lower bolster 10 arrive; The end that above-mentioned push rod 140 enters down die 100 is provided with an angled slide block 141, and this angled slide block 141 when formed product, can participate in formed product together with following die 100, assists the moulding overhead kick; On above-mentioned ejector retainner plate 12, be provided with a shutter 15 between ejector retainner plate 13 and the 3rd ejector retainner plate 14 down.
The utility model mould structure, die sinking after formed product, because product overhead kick position is special, if will will assist the angled slide block 141 of overhead kick moulding to eject at the beginning, will be stopped by product, and, if directly eject product, because the dual restriction of angled slide block 141 and following die 100, can damage the product overhead kick, therefore, at first need shutter 15 will go up ejector retainner plate 12, following ejector retainner plate 13 and the 3rd ejector retainner plate 14 locking one, do and eject for the first time, last ejector retainner plate 12, following ejector retainner plate 13 and the 3rd ejector retainner plate 14 move together, by thimble 130 and push rod 140, entire product and angled slide block 141 are together ejected down die 100, after product and following die 100 break away from, controlled opening/closing device 15, the 3rd ejector retainner plate 14 is decontroled, carried out again ejecting the second time, the 3rd ejector retainner plate 14 stop motions this moment, last ejector retainner plate 12 and following ejector retainner plate 13 drive thimble, the product overhead kick is ejected from the angled slide block 141 of assisting moulding by force,, leave cushion space for product overhead kick place owing to do not descend the resistance of die 100, overhead kick can be ejected by force, and be not damaged, make product break away from constraint fully, finish die sinking.
Simultaneously, above-mentioned angled slide block 141 also plays thimble 130 effects when ejecting for the first time, jointly product is ejected down die 100 with thimble 130, and this angled slide block 141 is big with the product contact area, can not leave a trace at product.
