Large-scale sliding block structure for preventing product from burring

Abstract

The invention discloses a large-scale sliding block structure for preventing a product from burring. The large-scale sliding block structure is used for forming a larger entire surface. The large-scale sliding block structure comprises a cavity insert, a core cavity and a large-scaling sliding block, wherein the core insert is combined with the cavity insert to form the product; the large-scale sliding block is arranged between the core insert and the cavity insert to form the larger entire surface of the product, and an inserting breaking parting plane is arranged between the large-scale sliding block and the core insert. Compared with the prior art, the large-scale sliding block structure for preventing the product from burring, disclosed by the invention, has the advantages that because the inserting breaking parting plane is adopted between the large-scale sliding block and the core insert, even if the large-scale sliding block bears a larger forming pressure when injection molding is performed, the large-scale sliding block retreats when being impacted, a gap generated by the inserting breaking parting plane between the large-scale sliding block and the core insert is relatively small, plastic can not enter the gap, so that the product can not form burrs.

Description

【Technical field】 [0001] The invention relates to a large-scale slider structure, in particular to a large-scale slider structure for preventing products from burrs. 【Background technique】 [0002] When plastic products are injection molded, a slider structure is used. see figure 1 , figure 2 , figure 1 is shown as a structural schematic diagram of a plastic product, figure 2 shown as figure 1 A schematic diagram of the local structure of the existing technology of the molding die for plastic products in China. [0003] Such as figure 1 As shown, the product 10 includes a large entire surface that needs to be formed by a slider, and the size of the product 10 is relatively large (for example, 590mm*370mm*60mm as shown in the figure). Such as figure 2 As shown, the product 10 is formed by a female mold core 11, a male mold core 12 and a large slider 13, wherein the large slider 13 forms a larger entire surface of the product 10. The large sliding block 13 and the ...
