Description

The demolding structure of injection mold

Technical field

It the utility model is related to injection mold field, more particularly to a kind of demolding structure of injection mold.

Background technology

In injection mold field, when button bit groove be present inside the plastic cement products for needing to be molded, mainly pass through pitched roof mechanism To match somebody with somebody synthesis type and core pulling.Specifically, carrying out ejection in vertical direction generally by injection machine or oil cylinder makes pitched roof mechanism Horizontal motion is carried out to realize the demoulding of button bit groove, but matches somebody with somebody synthesis type and the demoulding using pitched roof mechanism, structure is more multiple It is miscellaneous, add the manufacture difficulty of injection mold.Injecting products for internal button bit groove can not be deviate from by common pitched roof mechanism, It is general to be realized using the structure for changing product.But had the disadvantage that using the structure of change product：(1) cost is high, will One product splits into two parts, it is necessary to develop two molds, adds the development cost of mould, while produces two notes of needs Molding machine, finally also need to two assembling products together, add production cost.(2) outward appearance is influenceed, a production goes out Can have more beautiful outward appearance, split into two products, will necessarily the corresponding splicing line of product, lack the effect of overall appearance Fruit.
