Problems solved by technology

Due to the harsh working conditions of the injection mechanism, at present, squeeze casting equipment developed and produced at home and abroad is rarely equipped with a temperature detection device for the injection mechanism. Therefore, it is very necessary to develop a temperature detection device suitable for the characteristics of the extrusion casting injection mechanism.

Embodiment Construction

[0014] The injection mechanism of the squeeze casting machine is mainly composed of punch 1, pressure chamber 2 and push rod, among which punch 1 and pressure chamber 2 are the core parts of the injection mechanism and are also the objects of temperature detection. After the molten metal is poured in the pressure chamber 2, it enters the mold cavity from the pressure chamber 2 under the action of the punch 1 to complete the filling and solidification. The matching gap between the punch 1 and the pressure chamber 2 is very small, leaving very limited space for arranging thermocouples. Therefore, the design of the mechanical structure is very critical in the development of the temperature detector of the injection mechanism of the squeeze casting machine. In order not to affect the matching relationship between the punch 1 and the pressure chamber 2, the thermocouple is installed by punching a hole at the detection position.

[0015] At present, there are mainly three types of ...

Abstract

Provided is a temperature detector for an injection mechanism of an extrusion casing machine. Two or more punch thermocouple installation holes are formed in the punch and extend along the length direction, the punch thermocouple installation holes are of two different structures, the amount of the punch thermocouple installation holes of each structure is the same, and the punch thermocouple installation holes of the two different structures are distributed alternatively and uniformly in the punch; four rows of press-chamber thermocouple installation holes are arranged in the outer wall of a press chamber of the injection mechanism along the axial direction, each row includes four press-chamber thermocouple installation holes, and the press chamber is wrapped in a thermocouple fixing net for fixing thermocouples; and each installation hole is internally provided with the thermocouple and a lead thereof. According to the temperature detector, the fixation structure of the thermocouples is simplified, the temperature change condition of the injection mechanism can be detected in real time, the detector can be used in cooperation with a temperature controller of the injection mechanism to control the temperature of the injection mechanism, and the detector can be also used to conduct experimental research on the temperature distribution rule of the injection mechanism.

Description

technical field [0001] The invention relates to temperature detection equipment, in particular to a temperature detector used in the severe working condition of the injection mechanism of a squeeze casting machine. Background technique [0002] The injection mechanism is one of the key components of the squeeze casting machine, and the realization of the temperature detection of the injection mechanism is the premise of controlling the temperature of the injection mechanism. Due to the harsh working conditions of the injection mechanism, at present, squeeze casting equipment developed and produced at home and abroad is rarely equipped with a temperature detection device for the injection mechanism. Therefore, it is very necessary to develop a temperature detection device suitable for the characteristics of the extrusion casting injection mechanism. Contents of the invention [0003] The present invention aims to design a temperature detector used in the severe working cond...
