Description

Workpiece casting die

Technical Field

The utility model relates to the technical field of dies, in particular to a workpiece casting die.

Background

Workpiece casting is a method of manufacturing parts or articles of metal or other materials by a casting process, which is based on a mold to manufacture shaped parts. During casting, a mold is used to manufacture workpieces of a particular shape and size, which are typically cast from a liquid or semi-solid material at one time. When the traditional casting die is processed and cooled, the natural cooling mode is low in cost, long in time consumption, and short in time consumption if the casting die is directly put into cold water for rapid cooling, the surface of the die is easy to corrode when the casting die is used for a long time, the service life of the die is influenced, and in order to ensure the molding quality of a workpiece casting, the sealing performance between an upper die and a lower die of the die is required to be further improved.

In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides a work piece casting mould, includes mould and lower mould, go up the mould with the both sides of lower mould all are equipped with the fixed plate, it is fixed through bolt and nut between the fixed plate, the top of going up the mould and the bottom of lower mould all alternate and are equipped with not less than a cooling duct, the bottom both sides of going up the mould and the top both sides of lower mould all are equipped with the sealed pad that mutually support and use.

As an improvement, the bolt passes through the fixed plate on one side in sequence, the bottom of the bolt is fixed through two nuts, looseness is prevented, the connection strength is increased, and the tight connection of the upper die and the lower die is ensured to be integrated.

As an improvement, the top end of the upper die is provided with a handle which is connected in a rotating way, so that the upper die is convenient to take off.

As improvement, the inner walls of the upper die and the lower die are respectively provided with a wear-resistant coating, so that the inner surface is prevented from being worn, and the normal use of the die is prevented from being influenced.

As improvement, the upper die is provided with a pouring gate, so that the molten metal can be conveniently poured.

As an improvement, adjacent cooling pipelines are connected integrally through connecting pipes, so that cooling water is conveniently introduced into the cooling pipelines.

Compared with the prior art, the utility model has the advantages that: the cooling pipeline is inserted and arranged on the upper die and the lower die, cooling water is introduced into the cooling pipeline, so that the whole cooling pipeline is convenient to uniformly dissipate heat, the heat dissipation efficiency is high, the upper die and the lower die cannot be corroded, and the service life of the die is prolonged. Through the connection and fixation of the bolt and the double nuts, and the sealing gasket between the upper die and the lower die, the overall tightness is good, the dimensional accuracy and the surface quality of the cast workpiece are ensured, and the rejection rate is reduced.
