Sliding block ejection structure

Abstract

The invention provides a sliding block ejection structure which is applied to a formed product in a die. The die comprises an upper fixing plate, a female die plate, a female die core, a male die core, a male die plate, a first ejection plate, a second ejection plate, a third ejection plate and a lower fixing plate. The sliding block ejection structure comprises a sliding block bundle block, a sliding block seat, a sliding block insert, a sliding block shifting rod, an ejector pin and an ejector rod, wherein the sliding block bundle block is fixedly arranged in the male die plate; one side ofthe sliding block seat is fixedly connected with the sliding block bundle block, and the sliding block seat is provided with a through hole; one side of the sliding block insert is connected with theother side of the sliding block seat, and the other side of the sliding block insert is used for being matched with a clamping hook on the formed product; the bottom of the sliding block shifting rodis fixedly arranged on the third ejection plate, and the top of the sliding block shifting rod is of an inclined structure; the bottom of the ejector pin is arranged on the second ejection plate, andthe top of the ejector pin is used for ejecting the product; and the ejector rod is arranged in the lower fixing plate in a penetrating mode, and the top of the ejector rod is fixedly connected to thebottom of the third ejection plate. By means of the sliding block ejection structure, the problem that the product reject ratio is high due to the fact that a clamping hook structure is difficult todisengage is solved.

Description

【Technical field】 [0001] The invention relates to an ejection structure of a mold, in particular to an ejection structure of a slider. 【Background technique】 [0002] At present, due to installation and assembly requirements, many hook structures are designed on plastic products. In order to form these hook structures, an ejection device must be installed on the plastic mold to withdraw the hook structures of the product. On some plastic products, the hook structure faces the inner side of the product, and this inward hook structure is generally withdrawn by an oblique pin mechanism. The current oblique pin mechanism is simple in structure, and has disadvantages in the actual use process: on the one hand, the current oblique pin mechanism has a small withdrawal stroke, and is only suitable for withdrawing the hook structure with a small size. On the other hand, when the mold is opened and the product is ejected, in order to ensure that the hook structure is easy to disengag...
