[Technical Field]

[0001] This invention relates to the field of mold mechanism technology, and in particular to an internal slider mechanism for molds. [Background Technology]

[0002] like Figure 1 The product 50 shown has a first structure 20 and a second structure 30 on both sides that are straight. If the male and female molds are used to directly open the mold during production, the product 50 will be damaged due to the draft angle when the mold is opened.

[0003] Currently, this product (50) is formed by adding a slider to the mold. Figure 2 The diagram shows the mold core structure for forming this product 50. It requires a set of slider mechanisms on both sides of each product 50, namely, slider inserts 40 for forming the structure of product 50, and slider bodies for driving the slider inserts 40 out of the structure of product 50. Therefore, eight slider inserts 40 and corresponding slider bodies need to be set in a typical four-cavity mold. However, this results in a large mold volume and a high production cost for product 50.

[0004] In view of this, it is necessary to provide an in-mold slider mechanism to solve the above problems. [Summary of the Invention]
