Problems solved by technology

[0002] The coupler outer box is a protective device used to protect the coupler. However, with the development of technology, people have higher and higher requirements for the coupler outer box. As a result, the traditional coupler outer box production method has been unable to meet people's needs;
[0003] The traditional coupler outer box production method has certain disadvantages in use, because the existing coupler outer box production method directly puts the raw materials into the injection molding machine, melts them through the heating of the injection molding machine, and then injects them In the second process, due to the gaps between the raw materials, air bubbles appear inside the workpiece after injection molding, resulting in insufficient hardness and density of the workpiece. Secondly, due to the low temperature of the workpiece mold, when the raw material touches the mold On the surface, the raw material will partially solidify, resulting in a decrease in the surface density of the workpiece, thereby reducing the hardness of the workpiece to a certain extent. Therefore, we propose a production method for the outer box of the coupler

Abstract

The invention discloses a coupler outer box production method which comprises the following steps: raw material treatment: putting part of injection moulding raw material in a cleaning pool for cleaning, pouring the cleaned injection moulding raw material in a stirring machine, and putting the stirred injection moulding raw material in a drying oven to be dried; raw material mixing: after drying,adopting a pulverizer for pulverizing the raw material, putting the pulverized raw material in the stirring machine, and stirring the raw material in a pressurizing and temperature control manner; injection moulding: after stirring, preheating the raw material, putting the preheated raw material in an injection moulding machine for plastifying, and injecting the raw material in a die, and carryingout cooling forming to obtain a model; and surface treatment: uniformly smearing the pulverized raw material on the surface of the model, adopting an air heater to heat the surface of the model to melt the surface so as to obtain a formed model. According to the coupler outer box production method, through mutual cooperation of various raw materials, the hardness and the tenacity of the coupler outer box can be improved; and in addition, the coupler outer box can better resist collision to improve the using safety of the coupler.
