Plastic casing quick cooling device that moulds plastics

Technical Field

The utility model relates to an injection mold technical field specifically is a quick cooling device of plastic casing moulding plastics.

Background

An injection mold is a tool for producing plastic products; and is also a tool for giving the plastic product complete structure and accurate dimension. Injection molding is a process used to mass produce parts of some complex shapes. Specifically, the plastic melted by heating is injected into a mold cavity from an injection molding machine at high pressure, and a formed product is obtained after cooling and solidification. At present, various types of injection mold rapid cooling devices exist in the market, but the rapid cooling devices of the injection molds generally only pursue rapid cooling and ignore the phenomenon that the temperature difference between the inside and the outside of the mold is large in the cooling process of the mold, so that the mold is easy to deform and even damage in the past, and the surface temperature of a finished product in the mold is lower than the central temperature to cause heat accumulation in the middle of the finished product, so that the quality of the finished product is poor and even the finished product is damaged.

the utility model provides a quick cooling device of plastics shell moulding plastics, includes upper die base, die holder and mould body, the mould body includes the merciful and peaceful lower mould benevolence of mould, go up mould benevolence and inlay in the upper die base bottom, the lower mould benevolence inlays in the die holder top, be equipped with the pipe of moulding plastics with mould body intercommunication between upper die base and the die holder, be equipped with the cooling chamber between upper die base and the last mould benevolence, be equipped with the lower cooling chamber with last cooling chamber intercommunication between die holder and the lower mould benevolence, the upper die base top is equipped with the temperature controller, the temperature controller be equipped with the cooling water pipe of last cooling chamber intercommunication.

Preferably, the water temperature controller is provided with a cold water port, a hot water port and an integrated port communicated with the cooling water pipe, and the cold water port, the hot water port and the integrated port are communicated with each other.

Preferably, the upper die core is provided with a plurality of first connecting rods connected with the upper die base, and the lower die core is provided with a plurality of second connecting rods connected with the lower die base.

Preferably, the lower cooling cavity is communicated with a water outlet pipe.

Preferably, the water outlet pipe penetrates through the lower die base to extend outwards.

Compared with the prior art, the beneficial effects of the utility model are that:

can prevent when the cooling because the inside and outside inhomogeneous mould body that leads to of temperature of cooling water when the cooling effect of cooling water from damaging, and can prevent that the finished product from taking place to warp when the cooling and breaking, accomplish the operation back of moulding plastics at the mould body, the cooling water passes through the cold water mouth of temperature controller, the hot water mouth, through to cold water, the hot water mixes to flow into through integrated mouthful cooling pipe after reaching the uniform temperature and go into the cooling chamber and through space between the first connecting rod and the space between the second connecting rod flows into down in the cooling chamber, the cooling water after the use flows through the outlet pipe, can realize avoiding cooling water temperature and this internal temperature difference of mould too big through setting up hot water mouth and cold water mouth, the cooling process is gentler, play the guard action to the mould body when realizing the cooling.
