[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. Injection molding is an important plastic processing method. In the process of injection molding, plastic particles are usually put into the barrel from the hopper, and the barrel is used to inject the solution into the inside of the fixed mold.

[0003] If the barrel of an injection molding machine is directly exposed without any energy-saving and heat-insulating measures, the following problems are generally encountered when the barrel of an injection molding machine is used: 1. The heat loss is large and the overall heating efficiency is low; 2. Even if it is not used temporarily, it cannot be stopped and needs to be heated continuously to maintain the temperature, which consumes a lot of energy overall; 3. The surrounding temperature is high and the operator is prone to feel uncomfortable. An energy-saving and heat-insulating device for the barrel of an injection molding machine is urgently needed. In order to solve the above problems and to be able to perform energy-saving, heat-insulating and heat-insulating measures on the barrel of an injection molding machine, most of the existing practices are to cover the outside of the barrel of the barrel of the injection molding machine with a cover such as Figure 1 Although the vacuum insulation sleeve shown can achieve certain energy-saving, heat-insulating and heat-insulating effects, the two ends of the vacuum insulation sleeve are not closed, and some heat will still leak out from the two ends of the vacuum insulation sleeve, thereby affecting the overall energy-saving, heat-insulating and heat-insulating effects; in addition, such as the Chinese utility model patent with application number 201720743586.X, which discloses a screw extruder insulation device, such as the Chinese utility model patent with application number 202321513486.X, which discloses an insulation structure of an injection molding machine heating cylinder, although these insulation devices can achieve certain energy-saving, heat-insulating and heat-insulating effects, the two ends are not closed and the energy-saving and heat-insulating effects are relatively general.
