Highlight die and temperature control system thereof

Abstract

The invention discloses a highlight die and a temperature control system thereof, wherein the highlight die comprises a movable die, a fixed die or a cavity plate; an electric heating rod, a thermoelectric couple and a cooling channel are arranged on the fixed die or the cavity plate; the temperature control system comprises an electric heating control sub-system, a circulation water cooling sub-system and a compression air sub-system; the electric heating control sub-system is connected with the electric heating rod and the thermoelectric couple on the highlight die and is used for heating and controlling the temperature of the die; the circulation water cooling sub-system and the compression air sub-system are connected with the cooling channel on the highlight die to form a cooling loop for cooling the die; a 1# electromagnetic valve is arranged on a water supply pipeline of the circulation water cooling sub-system; a 2# electromagnetic valve is arranged on an air supply pipeline of the compression air sub-system; and various electromagnetic valves are connected with the electric heating control sub-system and are used for switching cooling water and compression air leaded to the die cooling channel. The highlight die and the temperature control system thereof disclosed by the invention have the characteristics of being convenient for use, short in forming period, high in production efficiency, energy-saving and the like.

Description

technical field [0001] The invention relates to a high-gloss mold and a temperature control system for the high-gloss mold. Background technique [0002] In the prior art, in order to obtain plastic parts with higher surface quality, high-gloss molds are often used. A heating / cooling channel is set on the fixed mold or cavity plate of the high-gloss mold, and its temperature control system includes a steam heating subsystem and a circulating water cooling subsystem, both of which are connected to the heating / cooling channel . When the mold is opened, the steam heating subsystem is controlled so that the hot steam enters the mold heating / cooling channel to heat the cavity, so that the temperature of the cavity rises to prepare for injection molding, and then starts the mold clamping injection molding, and completes the injection molding / holding pressure After switching to cooling, control the circulating water cooling subsystem to inject cooling water into the mold heating / ...

AI Technical Summary

Problems solved by technology

The temperature control system of the above-mentioned high-gloss mold needs to be equipped with boilers and steam pipes. First, the investment cost is high. Second, a certain air pressure must be maintained in the control cabinet during the production process, which consumes a lot of energy.

In addition, there are still defects such as long product molding cycle and low production efficiency.
