Abstract

The invention discloses a mold rapid cooling and rapid heating device. The device comprises a heater, a pumping, an auxiliary water tank and a valve set; the valve set is provided with a mold input opening, a mold return opening, a cold water inlet, a cold water outlet, a hot water inlet and a hot water outlet, wherein the mold input opening and the mold return opening are connected with a mold correspondingly; the valve set is operable to be in a first gear position or a second gear position, when the valve set is in the first gear position, the cold water inlet communicates with the mold input opening, and the cold water outlet communicates with the mold return opening; when the valve set is in the second gear position, the hot water inlet communicates with the mold input opening, and the hot water outlet communicates with the mold return opening; and the hot water outlet is connected with the auxiliary water tank, the auxiliary water tank is connected with the pumping, the pumping is connected with the heater, and the heater is connected with the hot water inlet. According to the mold rapid cooling and rapid heating device, the rapid switching of cold water and hot water in the mold can be realized, weld marks can be effectively eliminated, the injection molding process is reduced, the personnel expenditure is reduced, the cost is effectively reduced, and the delivery time is shortened.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a quick-cooling and quick-heating device for molds. Background technique [0002] In the injection molding process, the mold needs to be heated to a certain temperature and then cooled. The existing technology usually realizes the heating and cooling of the mold through the supply of hot water and cold water. However, the existing technology is difficult to quickly switch between heating and cooling , easy to form weld lines. Contents of the invention [0003] In view of this, the object of the present invention is to provide a mold rapid cooling and rapid heating device. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] A quick-cooling and quick-heating device for a mold, including: [0006] A heater, a pump, an auxiliary water tank and a valve group, the valve group has a mold input port, a mold return port, a c...
