Device and method of insert molding of injection mould

Abstract

A device and a method of insert molding of injection mould are applied in the injection mould. The device comprises a male template, a male mould core and an embedded insert arranged on the male mould core; a suction hole which is arranged at a position corresponding to the embedded insert on the male mould core and in a horizontal direction; a blow hole which is arranged in a vertical direction of the male template and vertically intersected with the suction hole; and an air inlet pipe arranged in the vertical direction of the male template, wherein one end of the air inlet pipe is connected with an automatic air supplying device and the other end extends into the blow hole. The device of the insert molding of the injection mould provided by the invention is simple in structure, can fix the embedded insert without adding a limit cylinder on the embedded insert and thus achieve the effect of insert molding, and is simple and convenient to operate.

Description

【Technical field】 [0001] The invention relates to an injection mold structure and a method for using the same, in particular to an injection mold insert forming device and a method thereof. 【Background technique】 [0002] In order to use different materials or different colors on injection molding products to meet the performance or appearance requirements of the product, the current conventional method is to use insert molding, that is, to inject a product as a pre-embedded insert. , and then install this pre-embedded insert at the corresponding position of another mold for injection molding to obtain composite structural products of different colors or materials. [0003] see figure 1 As shown, it shows a schematic structural view of an existing injection mold insert molding device. The existing injection mold insert molding device includes a male template 10, a male mold core 20 and an embedded insert 30 arranged on the male mold core 20 . [0004] In order to place th...

AI Technical Summary

Problems solved by technology

[0004] In order to place the pre-injected embedded insert 30 in the mold male core 20, and ensure that the embedded insert 30 will not fall off due to the vibration of the injection molding machine during subsequent injection molding production, the embedded insert 30 It is necessary to make a cylinder limit so that it can be loaded into the mold, and the cylinder needs to be cut off after the subsequent injection molding of the product to prevent the auxiliary cylinder from interfering with the product assembly, which will waste production time, and the product is easy to increase when it is ejected Ejection marks and cosmetic defects
