Abstract

The utility model relates to a cold hard casting hard mould for a ball body. The utility model is composed of a left mould and a right mould, which are mutually matched with each other. The left and right moulds are made into a hollow structure according to a mould cavity as a limiting surface, the inner of the left mould and the inner of the right mould form a cooled cavity, and a water inlet and a water outlet are respectively arranged on the upper part and the lower part of the cooled cavity. The hard mould of the utility model is made into a hollow cavity, cooling circulation water is arranged at the same time, the quick cooling of the casting in a short time can be realized, the long time high temperature heating of the hard mould can be avoided, the service life of the utility model can be enhanced, and the precision and the smoothness of the casting can be enhanced.

Description

Cold hard casting hard mould for ball body

The utility model relates to a kind of casting pattern, is specially a kind of cast-in chills die of spheroid.

Existing cast-in chills, because the problem of cooling fails to solve, the foundry goods cooling needs the long period, main is under hot conditions, reduced the service life of cast-in chills dies, adopted the method for above die, watering at present for quickening cooling, but therefore cause the pollution of working environment.

The purpose of this utility model is for providing a kind of cast-in chills die that foundry goods is cooled off at short notice fast.

The utility model is to adopt following measure to realize: the cast-in chills die of spheroid, form by the left and right mould that cooperatively interacts, it is hollow that left and right mould with the die cavity is that the interface is made, and makes to form cooling chamber in the left and right mould, at the upper and lower water inlet and the delivery port of being respectively equipped with of cooling chamber.

Die in the utility model has the existence of cooling circulating water simultaneously owing to made cavity, makes foundry goods cooling fast in short-term, like this owing to avoided the long high-temperature heating of die, the service life of having improved die.Cooling improves the precision fineness of foundry goods fast, and the crystalline structure of foundry goods is fine and closely woven simultaneously, and intensity, hardness, the wearability of foundry goods are improved.

Accompanying drawing 1 is the structural representation of single-piece molded;

Accompanying drawing 2 is the cutaway view of Fig. 1;

The utility model is a kind of cast-in chills die of spheroid, is made up of the left and right mould that cooperatively interacts, and it is hollow that left and right mould with the die cavity is that the interface is made, and makes to form cooling chamber in the left and right mould, at the upper and lower water inlet 1 and the delivery port 2 of being provided with of cooling chamber.

Claims

1, a kind of cast-in chills die of spheroid is made up of the left and right mould that cooperatively interacts, and it is characterized by: it is hollow that left and right mould with the die cavity is that the interface is made, and makes to form cooling chamber in the left and right mould, at the upper and lower water inlet and the delivery port of being respectively equipped with of cooling chamber.
