The purpose of this utility model is achieved through the following technical solutions:

A single-mould multi-bottle blow molding mold that is easy to replace the bottle-shaped structure, including a mold cavity and a bottle-shaped structure insert, and the mold cavity is sequentially connected by an upper mold body for forming the upper part of the bottle body, The middle mold body is composed of the lower mold body for positioning and supporting the bottom mold; the bottle-shaped structural insert is movably connected with the middle mold body, and its outer diameter matches the inner diameter of the middle mold body. The shape or decoration of the inner cavity of the bottle-shaped structural insert The stripes match the molded body of the bottle.

The bottle-shaped structural insert is movably connected with the middle mold body through screws.

The flexible connection between the bottle-shaped structure insert and the middle mold body is realized by setting a positioning groove on the middle mold body, and setting a protrusion matching the positioning groove on the bottle-shaped structure insert.

The flexible connection between the bottle-shaped structure insert and the middle mold body is realized by setting pins on the middle mold body and setting positioning holes matched with the pins on the bottle-shaped structure insert.

The flexible connection between the bottle-shaped structure insert and the middle mold body is realized by setting a positioning groove on the bottle-shaped structure insert, and setting a protrusion matching the positioning groove on the middle mold body.

The movable connection between the bottle-shaped structure insert and the middle mold body is realized by setting pins on the bottle-shaped structure insert and positioning holes matched with the pins on the middle mold body.

Compared with the prior art, the utility model has the following advantages:

The whole set of molds can produce plastic bottles with different shapes and decorative patterns by changing the inner cavity shape or decorative stripes on the bottle-shaped structural insert without changing the cavity body, and changing the bottle-shaped structural insert can be achieved by disassembling several One screw or aligning the positioning groove with the protrusion or the positioning pin with the positioning hole is easy to implement and the processing cost is low, especially when the whole set of molds has been installed on the blow molding machine, it has great cost advantages and convenience.

Description of drawings

Fig. 1 is the utility model easy to change bottle-shaped structure single model body multi-bottle type blow molding mold structural representation;

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is a schematic structural view of a single mold body multi-bottle type new blow molding mold that is easy to replace the bottle-shaped structure. As shown in Figure 1, a single mold body multi-bottle type new blow molding mold which is easy to replace the bottle structure is mainly composed of a cavity body 1 and a bottle structure insert 2. The mold cavity body 1 is composed of an upper mold body 11, a middle mold body 12 and a lower mold body 13 for positioning and supporting the bottom mould, which are connected in sequence. The cavity body 1 is composed of two symmetrical structures. The bottle-shaped structural insert 2 is located in the middle mold body 12, and its outer diameter matches the inner diameter of the middle mold body 12. Specifically, the bottle-shaped structural insert 2 and the middle mold body 12 are movably connected by connecting screws 3 and positioned with positioning pins 4 , Bottle-shaped structural insert 2. The shape of the inner cavity or the decorative stripes match the formed bottle body. The bottle-shaped structure insert 2 and the middle mold body 12 can also be flexibly connected by setting a positioning groove on the inner surface of the middle mold body 12, and setting a protrusion cooperating with the positioning groove on the bottle-shaped structure insert 2. Or a positioning groove is set on the outer surface of the bottle-shaped structure insert 2, and a protrusion cooperating with the positioning groove is set on the inner surface of the middle mold body 12 to be flexibly connected. It can also be that pins are set on the inner surface of the middle mold body 12, and positioning holes that cooperate with the pins are set on the bottle-shaped structure insert 2 to perform flexible connection; or the outer surface of the bottle-shaped structure insert 2 is provided with pins, The inner surface of the body 12 is provided with positioning holes matched with the pins for flexible connection.

The whole set of molds of the utility model can produce plastic bottles with different shapes and decorative patterns by changing the inner cavity shape or decorative stripes on the bottle structure insert 2 without changing the mold cavity 1, and when the insert is replaced Just install a few screws. Therefore, the method shown in this utility model is easy to adjust and replace, and the processing cost is low, especially when the whole set of molds has been installed on the blow molding machine, the replacement is more distinctive and practical.

The above is only a preferred feasible embodiment of the utility model, and does not limit the scope of protection of the utility model, so all equivalent structural changes made by using the utility model specification or accompanying drawings are included in the utility model within the scope of protection.
