Description

Die-casting die with insert

Technical Field

The utility model relates to a mould field of making, concretely relates to take die casting die of inserts.

Background

The die casting die is a tool for casting metal parts, a tool for completing a die casting process on a special die casting die forging machine, die castings are various in shapes, ejector pins are adopted to eject the die castings out of a die casting cavity after die casting is completed, the traditional die is matched with the die from top to bottom, the castings can be ejected out from one direction only after die casting is completed, if the castings are molded to be provided with side holes, although the die can be designed for die casting, the die in the side holes of the die castings after die casting is completed is connected with a lower die, an ejection mechanism in the lower die cannot eject the die castings out by upward ejection, and a new die casting die is urgently needed in order to solve the problem of demolding of the special molding of the castings with the side holes.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can die-casting out foundry goods take side pore structure's die casting die.

In order to achieve the technical purpose, the technical scheme of the utility model is that: the utility model provides a take die casting die of inserts, includes mould benevolence and lower mould benevolence, be equipped with the die on the mould benevolence, be equipped with the terrace die on the lower mould benevolence, be equipped with the recess that is used for placing the inserts on the terrace die, the recess includes first recess and second recess, the bottom of second recess is equipped with the locating hole, the holding ring has in the locating hole, the inserts includes orientation module, orientation module is corresponding with the second recess, orientation module's bottom surface is equipped with annular positioning groove, annular positioning groove corresponds with the holding ring, be equipped with a lug on orientation module's the side at least, when the recess was arranged in to the inserts, orientation module closely laminated with the second recess, the lug is located first recess, lug and first recess form the die casting chamber.

For more accurate positioning of the insert, there are two positioning holes.

The number of the grooves is two, and the grooves are symmetrically arranged on the male die.

And in order to discharge residual gas in the cavity during die casting, a plurality of slag ladles are arranged on the lower die core at the periphery of the male die.

Before die casting, the insert is arranged in the groove, the upper die core and the lower die core are assembled, a die casting cavity is formed between the female die and the male die, die casting is carried out through a die casting port on the female die, die casting liquid flows into the die casting cavity formed by the convex block and the first groove, a characteristic part is die-cast, after die casting is finished, the product and the insert are ejected out together through the ejection mechanism, and finally the insert and the product are separated from each other from the side direction to obtain a final product, so that characteristic die casting of the product is realized.

Compared with the prior art, the utility model provides a traditional mould die-casting area side pore structure's the difficult problem of foundry goods drawing of patterns.
