[0001] The utility model relates to the technical field of energy-saving and heat-insulating injection molding machines, in particular to a spliced ​​vacuum heat-insulating sleeve. Background technology:

[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 large amount 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 on the barrel of an injection molding machine, most of the existing practices are to cover the barrel of the injection molding machine with an insulation sleeve, 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 barrel, although it can achieve the effects of energy-saving, heat-insulating and heat-insulating, the existing insulation sleeves are mostly one-piece structures with a single length, which cannot well meet the use of injection molding machine barrels of different lengths.

The machine can be shut down when not in use to reduce energy consumption. The peripheral temperature of the barrel of the injection molding machine can be reduced to prevent the operator's working environment temperature from being too high, making the operator more comfortable, and can well meet the use of injection molding machine barrels of different lengths and models, with greater flexibility.

Specific implementation method:

[0022] The utility model will be further described below in conjunction with the accompanying drawings. Figure 1-4 As shown, the utility model includes a plurality of insulation sleeve units 1, and the insulation sleeve unit 1 is a cylindrical structure with a small opening at one end and a large opening at the other end. The end of the insulation sleeve unit 1 with a small opening is a splicing male end 11, and the end of the insulation sleeve unit 1 with a large opening is a splicing female end 12 matched with the splicing male end 11. The insulation sleeve unit 1 includes an insulation sleeve inner shell 13, an insulation sleeve outer shell 14, and an insulation sleeve vacuum layer 15 arranged between the insulation sleeve inner shell 13 and the insulation sleeve outer shell 14. The insulation sleeve units 1 are arranged side by side in sequence along the length direction of the barrel, and the splicing male ends 11 of each insulation sleeve unit 1 are respectively inserted forward into the splicing female ends 12 of the insulation sleeve units 1 adjacent thereto; compared with an insulation sleeve with an integrated structure and a single length, which can only be applied to injection molding machine barrels of certain length models, and when applied to injection molding machine barrels of other different length models, it is necessary to re-open the mold and design the insulation sleeve. The utility model is composed of a plurality of insulation sleeve units 1, which are not It can not only well insulate and heat-insulate the barrel of the injection molding machine, but also reduce heat loss and improve heating efficiency. It can be shut down when not in use temporarily to reduce energy consumption, reduce the ambient temperature of the barrel of the injection molding machine, prevent the working environment temperature of the operator from being too high, and make the operator more comfortable. In addition, a corresponding number of insulation sleeve units 1 can be selected according to specific usage requirements to form vacuum insulation sleeves of different lengths, which can well meet the use of injection molding machine barrels of different lengths and models, and has greater flexibility.

[0023] An insulation sleeve heat reflecting insulation layer 16 is provided on the outer side of the insulation sleeve inner shell 13.
