Description

Casting die utensil

Technical Field

The utility model belongs to the technical field of the mould processing technique and specifically relates to a casting die utensil is related to.

Background

The casting mold is a mold used for molding a casting in a casting molding process. In the cast molding process, a prepared casting material is generally injected into a casting mold and solidified, so that a product similar to the shape of a cavity of the casting mold is obtained.

General casting die possesses a die cavity, at the casting in-process, when casting die possesses a die cavity height higher, because the whereabouts stroke of casting raw materials when pouring into casting die is longer, the gravitational potential energy of casting raw materials is great, the casting raw materials can exert great power to the die cavity bottom when falling to the die cavity bottom down, because the hardness of swage is great, and the casting raw materials is generally for melting the metal that is in the liquid state after, under the interact of power, the die cavity bottom also exerts great power to the casting raw materials, make the casting raw materials take place to splash, thereby produce more waste residue, make the quality of casting fashioned goods relatively poor.

SUMMERY OF THE UTILITY MODEL

In order to improve the problem of poor quality of a cast product, the application provides a casting mould.

The application provides a casting die utensil adopts following technical scheme:

the utility model provides a casting die utensil, includes mould and lower mould, it is equipped with the die cavity to go up the mould, the top of going up the mould is equipped with the feed inlet, the feed inlet intercommunication go up the die cavity, the lower mould is equipped with down the die cavity, the bottom of die cavity is equipped with mends and connects the groove down, mend and be connected with on the inslot wall and mend and connect the psammitolite, mend the shape size that connects the psammitolite with mend the shape size in groove the same, go up the mould and connect the lower mould, go up the die cavity with the die cavity cooperation forms the die cavity that is used for the casting shaping down.

By adopting the technical scheme, the casting raw material is injected into the casting mould from the feeding hole, the casting raw material enters the cavity from the feeding hole, and after sequentially passing through the upper cavity and the lower cavity in the cavity, the casting raw material falls to the bottom of the lower cavity, and a larger force is applied to the bottom of the cavity when the casting raw material falls to the bottom of the cavity; on the other hand, the patching sand core has deformability, so that the product can be smoothly contracted during molding, the generation of cracks is reduced, and the quality of the cast and molded product is improved.
