Mould temperature control device

Abstract

The invention discloses a mould temperature control device, which comprises a temperature controller, a mould, and a water tank, wherein the temperature controller is internally provided with a hot water pipeline, a cold water pipeline, a compressed air pipeline, a mould advancing pipeline, a mould leaving pipeline, a mixer, a heating container, a hot water collecting container and a water replenishing container; the hot water pipeline, the cold water pipeline, and then compressed air pipeline are all connected with the mould advancing pipeline; the mould leaving pipeline and the cold water pipeline are both connected with the inlet of the mixer; the outlet of the mixer is connected with the water tank; the heating container, the mould advancing pipeline and the mould leaving pipeline are all connected with the mould; the hot water collecting container is respectively connected with the mould and the heating container; the water replenishing container is connected with the hot water collecting container; and a solenoid valve and a check valve are arranged among each container and each pipeline.

Description

technical field [0001] The invention relates to the technical field of high-gloss traceless injection molding, in particular to a temperature control device for a high-gloss traceless injection mold. Background technique [0002] High-gloss seamless injection molding technology is a new green injection molding technology without spraying. This technology can increase or decrease the surface temperature of the mold cavity in a short time through the rapid heating and cooling cycle control system of the mold temperature, so that when the plastic is at high temperature in the mold After the mold is filled, it is then rapidly cooled and molded under low temperature. [0003] At present, the temperature control of high-gloss non-marking injection molds is mainly realized by steam and cooling water. In the process of an injection molding cycle, the first step is that steam is output from the fuel or electric boiler, supplied to the interior of the mold by the controller to heat t...

AI Technical Summary

Problems solved by technology

In this way, the steam with waste heat after heating the mold cannot be recycled, and the heat brought out by the cooling water from the mold cannot be recycled.

In this way, the heat loss is large, the energy consumption is large, and the exhaust gas emitted by the fuel boiler has certain pollution to the environment.

In addition, a bulky boiler and controller equipment are required, and special pipes need to be laid next to the injection molding machine to complete the rapid cooling and rapid heating of the mold.

Such equipment requires large investment, large floor space, low operational safety, and inflexible on-site movement.
