[0003] Most of the conventional thermal insulation foam packaging boxes are molded after injection molding and foaming. After the molded thermal insulation foam packaging boxes are cooled, they are demoulded. In this way, manual demoulding is mostly used for demoulding. High, in the process of manual demoulding, it is easy to cause damage to the formed foam packaging box, which reduces the yield of thermal insulation foam packaging boxes, and at the same time, the efficiency of manual manual demoulding is slow, which cannot adapt to the mass production of foam packaging boxes , which brings inconvenience to the production of thermal insulation foam packaging boxes

Embodiment Construction
[0031] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0032] like Figure 1 to Figure 9 As shown, a method for making and forming an insulating foam packaging box uses a foam packaging box manufacturing device. The specific method of making thermal insulation foam packing box with the device is as follows:
[0033] S1. Device inspection: before using the foam packaging box manufacturing device to make thermal insulation foam packaging boxes, check the device;
[0034] S2. Injection molding: Operate the mobile plate 2 and the fixed frame 1 in the inspected foam packaging box production device in S1 above to cooperate with each other to...

The invention relates to the field of package manufacturing, in particular to a manufacturing and forming method for heat preservation foam packaging boxes. A foam packaging box manufacturing device is used and comprises a fixed frame, a moving plate and a demolding frame, the fixed frame is of a square structure, a plurality of mold grooves are formed in the fixed frame, and the mold grooves are all arranged in the reverse direction. First sliding grooves are formed in the two sides of the fixed frame correspondingly, first sliding blocks are slidably installed in the first sliding grooves correspondingly, first inserting grooves are formed in the first sliding blocks correspondingly, the moving plate is arranged in the fixing frame and located between the first sliding blocks, rotating rods are arranged on the two sides of the moving plate correspondingly, the ends, away from the moving plate, of the rotating rods are inserted into the first inserting grooves correspondingly, and a plurality of male molds are arranged at the top and the bottom of the moving plate correspondingly and correspond to the mold grooves respectively. According to the manufacturing and forming method for the heat preservation foam packaging boxes, a plurality of formed heat preservation foam packaging boxes can be automatically demolded, and the method is suitable for popularization.
Description
technical field [0001] The invention relates to the field of packaging manufacturing, in particular to a method for making and forming a thermal insulation foam packaging box. Background technique [0002] Insulation foam packaging box is a kind of outer packaging made of plastic foam for heat preservation and preservation. It has the advantages of light specific gravity, impact resistance, easy molding, beautiful shape, bright color, high efficiency and energy saving, low price, and wide range of uses. It is commonly used For the packaging and transportation of frozen products, vegetables and fruits or dairy products. [0003] Most of the conventional thermal insulation foam packaging boxes are molded after injection molding and foaming. After the molded thermal insulation foam packaging boxes are cooled, they are demoulded. In this way, manual demoulding is mostly used for demoulding. High, in the process of manual demoulding, it is easy to cause damage to the formed foam...
