Multifeed mould temperature control system of high light weld mark free shooting technique

Abstract

The invention provides a temperature control system of a multi-point die for a high light injection process without melt traces, which essentially comprises a heating boiler, a cooling pool, a pump, an air compressor, a mixer and a control unit. The heating boiler is connected with a steam pipeline; the cooling pool is connected with an cooling pipeline through the pump; the air compressor is connected with an air compressing pipeline; an outlet of the mixer is connected with the cooling pool; at least two branch pipelines are respectively connected with a set of die are arranged on the steam pipeline; the cooling pipeline has at least three branch pipelines and one of the branch pipeline is connected with an inlet of the mixer and the other branch pipelines are provided with the control valves and respectively connected with one set of die; at least two branch pipelines respectively connected with one set of die are arranged on the air compressing pipeline. By adopting the invention, one set of temperature control system can realize temperature control of a plurality of dies simultaneously; besides, the invention simplifies the structure, reduces the cost and occupied area of the system as well as enlarges operation space of technicians.

Description

technical field [0001] The invention relates to a temperature control system suitable for injection molds requiring high smoothness, no melting marks and high surface strength. It belongs to the technical field of injection molding in the subject of material processing. Background technique [0002] With the increasingly widespread application of plastic products, people have higher and higher requirements for the precision, surface quality and strength of plastic products. However, for some defects in the injection molding process, such as: welding marks, flow marks, and poor appearance quality of plastic products etc., ordinary injection molding process can not be solved. The high-gloss non-melt mark injection molding process can obtain high-precision and high-gloss products. In the injection molding process, the cavity or core of the injection mold is quickly heated to a temperature close to or higher than the heat distortion temperature of the polymer, and then the The...
