Problems solved by technology

[0002] For the mold structure that requires lateral slider demoulding and has front mold pins, the existing molds are arranged separately, and the slider demoulding and front mold pin demoulding are completed at the same time, but for the slider, front mold This kind of mold structure is not applicable when the positions of the insert pins overlap, which makes it necessary to design a complex mold structure to complete the demoulding, which makes the cost of the mold high

Abstract

The invention provides a structure of a slide capable of firstly vibrating a pin and then sliding out, so that a demould structure of a mould is simple when the positions of a slide block and a front mould insert pin are overlapped, and the cost of the mould is lowered. The structure comprises the front mould, a rear mould, an A plate, a B plate, an inclined guide column and a slide block, wherein the front mould and the rear mould are combined to form a cavity, the inner side of the slide block is tightly adhered to one side of the cavity, a concave hole is arranged on the position of the cavity on the slide block, the structure is characterized in that the lower end of an ejector pin of the front mould insert penetrates through an installation hole of the slide block and then goes deep into the concave hole, a raised block is arranged on the middle part of the ejector pin of the front mould insert, a compressing block installation slot is formed above the installation hole and is located on the upper end face of the slide block, a compressing block is located in the compressing block installation slot, and a guide cavity is formed between the lower end face of the compressing block and the middle part of the installation hole.

Description

technical field [0001] The invention relates to the structural technical field of product molds, in particular to a structure in which a needle is ejected first and then ejected. Background technique [0002] For the mold structure that requires lateral slider demoulding and has front mold pins, the existing molds are arranged separately, and the slider demoulding and front mold pin demoulding are completed at the same time, but for the slider, front mold When the positions of the insert pins overlap, this kind of mold structure is not suitable, so that it is necessary to design a complex mold structure to complete the demoulding, which makes the cost of the mold high. Contents of the invention [0003] The invention provides a structure where the needle is ejected first and then moves out, which makes the demoulding structure of the mold simple when the positions of the slide block and the front mold inserting needl...
