Anti-collision device for slide block

Abstract

The invention discloses an anti-collision device for a slide block, which comprises a moving mold retaining plate and a fixed mold, wherein a moving mold is arranged between the moving mold retaining plate and the fixed mold; a slide block is arranged in the moving mold; the lower part of a non-glue position of the slide block is provided with a thimble; the moving mold retaining plate is provided with an upper thimble plate and a lower thimble plate; an anti-collision needle is arranged on the upper thimble plate; the lower part of a glue position of the slide block is provided with a hole matched with the anti-collision needle. The anti-collision device can avoid the collision between the thimble and the glue position of the slide block to damage the slide block, so that the maintenance cost of the mold is indirectly reduced, and the mold can be used for injection molding to produce a product meeting the quality requirements.

Description

technical field [0001] The invention relates to a sliding block anti-collision device, which belongs to the field of plastic mold manufacturing. Background technique [0002] Sliders are usually used in mold design. For the positioning of the sliding direction of the slider, springs, wave screws, limit screws, etc. are often used in existing designs, but the use of these devices cannot fully guarantee the sliding The positioning problem of the sliding direction of the block, especially in some products, there will be a glue position at the bottom of the slider, and the thimble must be placed. At this time, it is necessary to consider ensuring the accuracy of the slider’s withdrawal and ensuring that the slider is withdrawn in place. In the existing production It is often encountered that the slider is not withdrawn in place, causing the thimble to collide with the slider when ejecting the product, and there are many cases of crashing the slider.
