Aluminum alloy mould capable of automatically controlling temperature

Abstract

The invention discloses an aluminum alloy mould capable of automatically controlling temperature. The aluminum alloy mould capable of automatically controlling the temperature comprises an aluminum alloy lower mould body, an aluminum alloy upper mould body, a mould cavity, temperature-controlling pipes, an electronic valve, a controller, a transmission pipe, and temperature sensors. The temperature-controlling pipes are correspondingly arranged inside the aluminum alloy upper mould body and the aluminum alloy lower mould body; one end of the transmission pipe is connected with the temperature-controlling pipes, and the other end of the transmission pipe is connected with the electronic valve; the temperature sensors are arranged on the inner parts of the aluminum alloy upper mould body andthe aluminum alloy lower mould body; and the electronic valve and the temperature sensors are electronically connected with the controller. According to the aluminum alloy mould capable of automatically controlling the temperature, in the injection molding process of products, the controller controls the electronic valve according to written injection mould temperature parameters to control the flow speed and the flow amount the water or oil inside the temperature-controlling pipes so as to control the temperature of the aluminum alloy mould, and heat dissipation, heating and temperature controlling of the aluminum alloy mould are realized; and automatic control is achieved, and aluminum alloy mould is simple in structure, low in cost, high in practicability, and suitable for large-scaleinputting use.

Description

technical field [0001] The invention belongs to the technical field of molds, in particular to an aluminum alloy mold with automatic temperature control. Background technique [0002] Aluminum alloy molds are mainly used for proofing and mold opening of small batches of products, and their service life is generally not long, but at the same time, because of their simple manufacture and low cost, they are also deeply loved by mold companies. One of the shortcomings of the aluminum alloy mold is that it is easy to crack and bend after a period of use. The temperature of the mold during the injection molding process of the mold also affects the injection-molded products. Too low a surface temperature of the mold usually leads to poor appearance of the molded parts, and also causes the size of the product to become smaller when the product is used at a high temperature; uneven heat distribution in the mold will cause It will lead to different shrinkage, lead to excessive size o...

One of the shortcomings of the aluminum alloy mold is that it is easy to crack and bend after a period of use. The temperature of the mold during the injection molding process of the mold also affects the injection-molded products. Too low a surface temperature of the mold usually leads to poor appearance of the molded parts, and also causes the size of the product to become smaller when the product is used at a high temperature; uneven heat distribution in the mold will cause It will lead to different shrinkage, lead to excessive size of parts, and in severe cases, it will prolong the production cycle and reduce production efficiency; when making large products, it is necessary to keep the mold at a certain temperature, so as to ensure that the products produced will not be underfilled or strained occur
