Description
Technical field
The utility model relates to technical field of mold, in particular to a kind of injection molding male model and the injection molding containing the injection molding male model
Mold.
Background technique
Injection mold is a kind of tool for producing plasthetics, is also to confer to plasthetics complete structure and accurate dimension
Tool.Injection mold is generally arranged on injection molding machine, and specific forming process is that injection molding machine injects the plastic high voltage of heated thawing
In the die cavity of injection mold, after cooling and solidifying, formed product is obtained on handware.
Injection mold generally includes male model and master mold, male model and master mold being arranged separately on injection molding machine one on the other,
When injection molding, injection molding machine drives male model and master mold close, so that male model and master mold mutually fasten, forms die cavity, to injection molding it
Afterwards, injection molding machine drives male model and master mold to separate, and ejects male model by handware and product, after make injection molding machine that handware be driven to move
It is dynamic, product is delivered to subsequent processing.
However, male model used at present mostly uses primary ejection in the prior art, cause ejection height limited, even
Product is also adhered on male die core, so that product may be broken when product moves together with handware, rather than
It is moved together away with handware.
Utility model content
Based on this, the injection mold the purpose of the utility model is to provide a kind of injection molding male model and containing the injection molding male model,
To ensure that product can move together away with handware.
A kind of injection molding male model, comprising:
