A copper die casting system with high yield

Abstract

The invention provides a copper mold die-casting system with high yield applied to the field of copper die-casting. By setting a combined movable mold, the movable plate of the cavity is automatically separated and ejected when the movable mold is withdrawn from the limiting and shaping mechanism. , so that the copper mold automatically falls out of the mold, and there is no need to set the ejector device to eject the copper mold. At the same time, dispersing the moving mold is more conducive to speeding up the cooling and heat dissipation of the moving mold and improving the efficiency of shaping; by setting the dual-channel mode The cooling module is used for heat dissipation, and the cooling liquid is used to absorb the heat of the fixed mold and then volatilize. At the same time, the energy is converted into the upper kinetic energy of the linkage mechanism to drive the cold air in the cold channel to circulate in the inner channel faster, and the cooling effect can be improved without external power. Better The energy saving and environmental protection characteristics of the die casting device are greatly improved, and the production efficiency is also improved.

Description

technical field [0001] The invention relates to the field of copper die casting, in particular to a copper die die casting system with high yield. Background technique [0002] The production of copper molds mainly adopts the die-casting process. The quality of the die-casting process determines the quality, production efficiency and service life of the copper molds. Existing copper mold production equipment includes fully open and semi-open production methods. Although these two production methods can improve production efficiency, they both have shortcomings: the copper mold produced by the fully open production method has poor organization density, many internal defects, and semi-open production methods. The copper mold made by the open production method also has poor organization density and short service life. [0003] After extensive search by the team, we learned that the existing copper die-casting systems mainly include JP2006336079A, KR101264830B1 and KR101246598B...

Existing copper mold production equipment includes fully open and semi-open production methods. Although these two production methods can improve production efficiency, they both have shortcomings: copper molds manufactured by fully open production methods have poor tissue density, many internal defects, and semi-open production methods. Copper molds manufactured by open production methods have poor microstructure and short service life

[0003] After a massive search by our team, we learned that the existing copper die-casting systems mainly include JP2006336079A, KR101264830B1 and KR101246598B1, among which the die-casting system disclosed by the publication number CN104325107B is particularly representative, and the system is delivered by an automatic soup feeding device. soup stock; add soup stock through the quantitative soup device and the heat preservation device; complete the quantitative feeding and vacuum die-casting procedures through the injection device, vacuum device and mold clamping device, but the degree of automation of this system is still It is not perfect. At the same time, the existing movable mold or fixed mold is generally equipped with an ejector mechanism to facilitate the return of materials, but the effect of this mechanism is average. Often, after the ejector is ejected, it is necessary to manually remove the copper mold from the mold or ejector. , and because of the high melting point of copper alloy, a special filling spoon is generally used to add the molten material, but this kind of filling spoon will still wear out because it is often exposed to high temperature environments, so certain copper melts will also appear. Slag inclusions, these slag inclusions also seriously affect the characteristics and signs of the copper mold, and because the cooling rate of the fixed mold and the moving mold in the cold chamber die-casting device is also one of the factors that determine the production efficiency, so how to solve the above problems to improve the copper The production efficiency of die-casting and the service life of the lifting device are the main research directions of the current die-casting device
