Automatic temperature control apparatus of mould

Abstract

The invention relates to a mold temperature control system, in particular to a mold temperature automatic control device. It includes a heating circulation system, a cooling circulation system and an operating working water tank circulating system. The output end of the water tank temperature adjustment control device in the operating working water tank circulating system is respectively connected with the water tank cold compensation adjustment system and the heating pipe control end, and the input end is connected with the control end of the heating pipe. The output end of the temperature sensor in the water tank is connected, and the control end is connected with the output end of the temperature sensor arranged on the mould. Its purpose is to design an automatic mold temperature control device that can effectively control the mold temperature and avoid overshooting of the mold temperature when the mold is heated or cooled. Compared with the existing technology, it has the advantages of automatic mold temperature control, accurate control range, labor saving, time saving, material saving and power saving.

Description

technical field [0001] The invention relates to a mold temperature control system, in particular to a mold temperature automatic control device. Background technique [0002] When molding plastic products, in order to ensure the injection molding accuracy of the product and prevent defective products, it is usually necessary to control the working temperature of the mold within a certain range. The Intellectual Property Literature Publishing House disclosed a mold temperature control system with an application number of 02124412.X on the China Intellectual Property Network on August 13, 2003. Warm water or cold water is used to adjust and control the technical solution of mold working temperature, and this patented technological innovation only solves the technical problem of back pressure in the system pipeline, but there are still many deficiencies: (1) The mold temperature cannot be controlled automatically, only The mold is heated when the mold is cold, and the mold is ...

Intellectual Property Literature Publishing House disclosed a mold temperature control system with an application number of 02124412.X on China Intellectual Property Network on August 13, 2003. Warm water or cold water is the technical solution to control the working temperature of the mold, and the innovation of this patented technology only solves the technical problem of back pressure in the system pipeline, but there are still many deficiencies: (1) It cannot automatically control the mold temperature, only When the mold is cold, the mold is heated, and when the mold is hot, it is cooled, which can only be operated repeatedly, wasting electric energy, and the equipment becomes old and damaged quickly; (2) The cushioning problem cannot be solved when the mold is overheated or overcooled, and the mold temperature cannot be controlled at the set value Within the scope of the product, the precision of the product produced within 24 hours is inconsistent, and the product quality is unstable. Therefore, it is necessary to arrange special personnel to supervise and inspect, which is a waste of manpower; (3) when the mold is inspected, cleaned and repaired midway, the mold temperature changes. It is necessary to reheat the mold to the working temperature of the mold, wasting production time
