Slide block demolding mechanism

Abstract

The invention discloses a slide block demolding mechanism, and belongs to the field of demolding apparatuses in mold processing. The slide block demolding mechanism comprises an upper template, a lower template, a slide block, a slide block seat, a shovel base, a positioning seat, a hexagonal socket head cap screw, springs, two horizontal guiding briquettes, pins and two inclined guiding briquettes, the slide block, the slide block seat and the positioning seat are arranged between the cavity of the upper template and the cavity of the lower template, the slide block seat is provided with an inclined T-shaped chute, the slide block is correspondingly provided with an inclined slide projection, the slide block seat is movably connected with the slide block through the cooperation of the inclined T-shaped chute and the inclined slide projection, the two horizontal guiding briquettes and the two inclined guiding briquettes are symmetrically arranged at two sides of the slide block and the slide block seat and are fixed on the lower template through the pins, and the shovel base is arranged in the slot of the slide block seat. The shovel base releases locking force on the slide block under the action of a mold opening machine of an injection machine in order to make the slide block and the slide block seat rapidly slide away from a product under the driving of the reset force of the springs in order to make the product nondestructively demolded.

Description

technical field [0001] The invention relates to the field of mold ejection devices in mold processing, in particular to a slider ejection mechanism. Background technique [0002] During the processing of injection molds, many products have undercuts in the fixed mold direction, which cannot be demolded and ejected normally. It is necessary to make additional oblique sliders to demould. When the ribs of the product are deep, the product is easy to slide. If the pieces stick together, the product cannot be opened, or even the product is damaged, and the demoulding effect is not ideal. In the prior art, there are also demoulding devices using inclined sliders, such as the "automobile turn signal mold buckle inclined top mechanism" with the patent No. The inclined sliding rod and the inclined sliding block make the inclined sliding block disengage from the buckle to complete the demoulding, the structure is more complicated, and the processing cost is higher.

Problems solved by technology

[0002] During the processing of injection molds, many products have undercuts in the fixed mold direction, which cannot be demolded and ejected normally. It is necessary to make additional oblique sliders to demould. When the ribs of the product are deep, the product is easy to slide. The block sticks, causing the product to fail to open the mold, or even strain the product, and the demoulding effect is not ideal

In the prior art, there is also a demoulding device using inclined sliders, such as the "automobile turn signal mold buckle inclined top mechanism" with the patent No. The inclined slider and the inclined slider are used to disengage the inclined slider from the buckle to complete the demoulding. The structure is more complicated and the processing cost is higher.
