[0001] The utility model relates to the technical field of injection molding machines, in particular to a heat-insulating protective cover for an injection molding machine which is easy to disassemble and assemble. Background Art

[0002] The injection molding machine heats the plastic particles into a melt and then injects them into the mold and cools them down to obtain plastic products in the desired shape. However, the heating tube will cause the heat to be dissipated into the air during the heating and transportation process, which is very wasteful. The heat loss can be reduced by a heat insulation protective cover.

[0003] For example, Chinese utility model patent CN219838111U discloses a heat-insulating protective cover for an injection molding machine. The heat of the heating cylinder inside the device can circulate internally through the provided heat-insulating interlayer, thereby increasing the heat dissipation time and better protecting the internal temperature of the heating cylinder. An insulating layer is provided on one side of the heat-insulating interlayer, and the provided insulating layer can effectively prevent employees from accidentally touching and getting burned.

[0004] However, it still has the following disadvantages: the heat insulation protective cover cannot adjust the size of the opening so that it cannot fit tightly with the injection pipe of the injection molding machine, thereby causing partial heat loss.

[0005] Based on this, the utility model designs an easily disassembled heat-insulating protective cover for an injection molding machine to solve the above problems. Utility Model Content
