Problems solved by technology

The disadvantage of the first method - high temperature oil heating is that it cannot be used in clean room injection molding, because the high temperature oil mold temperature machine cannot avoid oil mist, which will pollute the clean room environment; the disadvantage of the second method - electric heating rod heating is The heating is uneven, and the molding quality and stability are difficult to be guaranteed; at the same time, the common disadvantages of the above two methods are that the mold as a whole runs at high temperature, the expansion of the steel is large, and the accuracy of each part of the mold is difficult to guarantee. Stable with high wear and low die life

Embodiment 1

[0090] An injection mold such as figure 1 As shown, it is mainly composed of mold base, mold core, heat insulation layer, heating equipment and cooling equipment. Among them, the mold base covers the mold core, and the mold base and mold core are separated by heat insulation layer. The heat insulation layer is titanium alloy heat insulation board , the structure of the titanium alloy heat shield is shown in image 3 shown. The injection mold can be opened and closed up and down, the upper part and the lower part of the mold base are respectively connected with the cooling device, and the upper part and the lower part of the mold core are respectively connected with the heating device.

Embodiment 2

[0092] An injection mold such as figure 2 As shown, including mold base, mold core, heat insulation layer, heating equipment, cooling equipment, flow channel for cooling, flow channel for heating and thermometer, wherein, the mold base covers the mold core, and the mold base and The mold core is separated from the heat insulation layer, and the heat insulation layer is a titanium alloy heat insulation board. The structure diagram of the titanium alloy heat insulation board is as follows image 3 shown. The injection mold can be opened and closed up and down, and the upper and lower parts of the mold base are respectively provided with flow channels for cooling. The lower parts are respectively provided with flow channels for heating. The heating equipment is high-temperature water heating equipment, which heats the mold core through the flow channels inside the mold core. The temperature wire monitors the temperature of the mold base and mold core.

Abstract

The invention provides an injection mold and application of the injection mold, and relates to the technical field of molds. The injection mold comprises a mold frame, a mold core, a heat insulation layer, heating devices and cooling devices. The mold frame wraps the mold core, the mold frame and the mold core are separated by the heat insulation layer, the heating devices are connected with the mold core and used for heating the mold core, and the cooling devices are connected with the mold frame and used for cooling the mold frame. The situation that the mold frame stably accomplishes opening, closing, ejection, core pulling and other mold actions at the low temperature is guaranteed, the situation that the mold core forms a high-quality molded product at the high temperature is also guaranteed, and the mutual interference between the mold frame and the mold core is relatively small. The problem that a traditional integrated heating mold cannot give consideration to the temperature contradiction between mold frame operation and mold core forming is solved, the service life of the mold is prolonged, and the forming quality of the mold is improved. The injection mold can be used for resin injection molding.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an injection mold and its application. Background technique [0002] With the development of polymer materials, high-temperature resins have been used more and more widely in various fields, and most application scenarios require injection molding technology to realize product molding. Usually, this type of resin requires the temperature of the mold to be as high as 170°C. At present, the mainstream technologies for mold heating in the industry include: 1. High temperature oil to heat the mold as a whole; 2. Electric heating rod to heat the mold as a whole. The disadvantage of the first method - high temperature oil heating is that it cannot be used in clean room injection molding, because the high temperature oil mold temperature machine cannot avoid oil mist, which will pollute the clean room environment; the disadvantage of the second method - electric heating rod heating is Th...
