Problems solved by technology

In the production process, when the mold is opened and the parts are taken out, if the friction force of the fixed mold relative to the part is greater than the friction force of the movable mold to the part, the part will stay in the fixed mold, because the fixed mold does not have an ejector pin, and the ejector pin is often set on the movable mold. On one side, it is difficult to remove the part from the fixed cavity of the mold, thus affecting the production efficiency
In the current mold design, the deep cavity part of the product is designed on the movable mold side, and the shallow cavity part is designed on the fixed mold side, but it still cannot guarantee the occurrence of the above phenomenon

Embodiment Construction

[0012] Such as figure 1 , figure 2 A kind of easy-off pattern die-casting mold shown, comprises fixed mold assembly, and its difference is: the processing surface of the fixed mold assembly that the present invention adopts is provided with movable mold assembly, and fixed mold assembly and A cavity is formed between the movable mold components. At the same time, considering the need of demoulding, a through hole is arranged on the movable mold assembly, and a thimble assembly is arranged in the through hole. Moreover, in order to facilitate rapid demoulding, a demoulding connecting end is distributed on the working end of the thimble assembly located in the cavity.

[0013] As far as a preferred embodiment of the present invention is concerned, considering the demoulding requirements in actual work and operation, and avoiding the breakage of the thimble assembly due to uneven force, the thimble assembly used is composed of at least three elongated thimbles.

Abstract

The invention relates to an easy-to-remove type die-casting die. The easy-to-remove type die-casting die comprises a fixed die component and is characterized in that a moving die component is arranged on a machining face of the fixed die component. A cavity is formed between the fixed die component and the moving die component. A through hole is formed in the moving die component. An ejector pin component is arranged in the through hole. A die removing joint end is distributed on a working end head, located in the cavity, of the ejector pin component. Therefore, die removing operation of parts of a die-casting die is simple, machining is convenient, cost is not added basically in the process of die manufacture, the phenomenon that the die-casting parts are remained in a fixed die and can not be taken out is thoroughly changed and therefore production efficiency is improved.

Description

technical field [0001] The invention relates to a mold, in particular to an easy-off mode die-casting mold. Background technique [0002] At present, the die-casting process has been widely used in the industry and has become an important production method for many parts in the fields of automobiles, electrical equipment, and communications. It has the advantages of fast forming speed, high work efficiency, clean environment, smooth product surface, and complex and diverse forming parts. Features. In the production process, when the mold is opened and the parts are taken out, if the friction force of the fixed mold relative to the part is greater than the friction force of the movable mold to the part, the part will stay in the fixed mold, because the fixed mold does not have an ejector pin, and the ejector pin is often set on the movable mold. On the one hand, it is difficult to remove the parts from the fixed cavity of the mold, thus affecting the production efficiency. ...
