AI Technical Summary

Technical Problem

The existing mold design has several problems: the panel does not have guide pillars to guide the hot nozzle, which makes the hot nozzle easy to damage; the design of the scraper on the slide is time-consuming; the number of pin holes on the slide pressure plate and template is large, which makes the processing complicated; the parting line of the product is not neat; and the lack of delayed ejector pin design on the slide causes the product to deform.

Method used

The guide pillar body is set in the mold to protect the hot nozzle, the A plate scraper design is improved to a unidirectional step, the pin hole is eliminated and screws are used for fixing, the step design is added and the delay ejector pin design is added to the slide.

Benefits of technology

It effectively protects the hot nozzle, reduces maintenance costs, saves processing time, improves production efficiency, ensures neat product parting lines, and reduces the defect rate.

Abstract

The utility model relates to the technical field of mould manufacturing, specifically relates to a mould of button front hand support lower body, the design has installed the guide pillar of hot nozzle guidance on the panel, and the guide pillar length is greater than hot nozzle body, can play effective protection effect in the assembly process, prevents hot nozzle damage, the shovel machine design improvement of A plate upper line position is only one direction has a step in a step, has saved processing working hours, the line position pressing plate is through the mode that cancels the dowel, opens the recess on B plate and adds screw fixed mode, has simplified the processing procedure, the product has added the section difference design, makes each processing error be within the controllable range, the line position has added the delayed ejector pin design, when the mould is opened, the line position retreats first, the inside ejector pin will first resist the product because the shovel machine has a straight surface and retreats again after the rear mould core removes the big rubber position, guarantees that the product does not deform, the size satisfies the requirement, has reduced the product's defective rate, has reduced the production cost.
