Automatic extrusion structure

Abstract

The invention relates to an automatic extrusion structure. The structure comprises: a material carrying assembly, wherein the material carrying assembly comprises a bottom plate and a hollow shell arranged on the bottom plate, and the shell is provided with a barrel integrally formed at the bottom of the shell and a rotary table mechanism fixed to the barrel; and a plurality of extrusion assemblies arranged in the shell at intervals, wherein each extrusion assembly comprises a lifting shaft, an extrusion mechanism and a first driving device, the lifting shaft is arranged at the bottom of the bottom plate and the bottom of the shell in a sealing and penetrating mode, the extrusion mechanism is arranged at the top of the lifting shaft, and the first driving device is connected with the lifting shaft and used for driving the lifting shaft to ascend and descend. Automatic feeding test equipment is simple in structure, high in automation degree, capable of achieving accurate control over the pressure in the automobile wax package, high in test structure accuracy and high in safety coefficient.

Description

technical field [0001] The invention belongs to the technical field of testing, and in particular relates to an automatic extrusion structure. Background technique [0002] Wax-type car thermostat is a valve that controls the flow path of car engine coolant. It can automatically adjust the amount of water entering the radiator according to the principle of internal paraffin wax thermal expansion and contraction, so as to ensure that the engine works within a suitable temperature range. Play the role of saving energy consumption. [0003] In the prior art, when the wax bag of the automobile thermostat is tested, the wax inside it needs to be melted, and through the principle of thermal expansion and contraction, the interior has an initial pressure to meet the standard of normal use, and then the performance is tested. However, in the prior art, before the test, the internal air pressure cannot be controlled, and the internal air pressure may be too small, resulting in inacc...
