Technical Field

[0001] This utility model relates to precision manufacturing technology, and in particular to injection molding. Specifically, it relates to a quick mold change mechanism for multi-cavity injection molds. Background Technology

[0002] In the field of injection molding technology, some products are designed with a series of designs to suit different applications. For example, the base slots have various shapes, such as round, triangular, and square, and the side slots have different numbers of positioning slots.

[0003] The current design method generally adopts a single base slot shape and a single mold for the side slots, which seriously wastes production resources. In addition, setting up multiple molds requires a long time, which affects production efficiency to some extent.

[0004] Therefore, it is necessary to provide a quick mold change mechanism for multi-cavity injection molds. Utility Model Content

[0005] The purpose of this invention is to provide a quick mold change mechanism for multi-cavity injection molds.

[0006] The technical solution is as follows:

[0007] A quick mold change mechanism for a multi-cavity injection mold includes a base slot corresponding to a core set on the lower mold, a lower mold cavity set on the lower mold, the base slot corresponding to the core set in the middle of the lower mold cavity, a side latch portion corresponding to the core set on the base slot, and the side latch portion corresponding to the core set on a side latch portion setting groove.

[0008] The base slot corresponding to the insert is detachably set on the lower mold. The base slot corresponding to the insert has a slot seat corresponding part, which is round, has a triangular prism shape, or a square groove.

[0009] The side bayonet portion has several corresponding posts on the insert core, and the number of corresponding posts is 1, 3, or 5.

[0010] By switching between round, triangular, or square groove shapes to correspond to the required products, and by setting one, three, or five corresponding side posts, a highly versatile injection molding mold suitable for the production of a series of products can be formed.

[0011] Furthermore, the lower mold is provided with a base slot corresponding to the insert slot.

[0012] Furthermore, the base slot corresponds to the inlay slot, and the base slot is designed to correspond to the shape of the lower end of the inlay.

[0013] Furthermore, the base slot corresponding to the insert core is provided with no less than 3 embedding positioning slots, and the corresponding base slot corresponding to the insert core is provided with embedding positioning posts.

[0014] Furthermore, the corresponding post of the side bayonet is fixedly set on the corresponding block of the side groove.

[0015] Furthermore, the side slot corresponding block is provided with a side bayonet corresponding post setting hole slot, and the side bayonet corresponding post is directly inserted into the side bayonet corresponding post setting hole slot through the bottom insertion part.

[0016] Compared with existing technologies, this utility model ensures rapid and orderly production by using a highly versatile injection molding mold adapted to the production of a series of products. Attached Figure Description

[0017] Figure 1 This is one of the structural schematic diagrams of this utility model.

[0018] Figure 2 This is the second structural schematic diagram of this utility model. Detailed Implementation
