Description

Technical Field

[0001] The utility model belongs to the technical field of plastic pallets, in particular to an injection molding machine for a plastic pallet. Background Art

[0002] Plastic pallets refer to a logistics unit that is used in conjunction with logistics equipment such as forklifts, shelves, etc. It is mainly used for storing, loading and turnover of goods. Moreover, plastic pallets are an indispensable logistics unit in modern logistics warehousing. Plastic pallets have the characteristics of anti-corrosion, anti-moisture, anti-rust, anti-insect and no mold.

[0003] At present, the staff operates the injection molding machine to produce plastic pallets. The injection molding machine refers to the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastic plastics or thermosetting plastics. The injection molding machine is composed of a machine body, a control panel, a display screen, an indicator light, a material barrel, a stirring component, a hot melt component, an injection molding component, and a mold component.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the use of the existing injection molding machine, the driving assembly is controlled to adjust the position of the movable mold, thereby adjusting the distance between the movable mold and the fixed mold, and then opening and closing the mold assembly. However, it is inconvenient to adjust the position of the two molds at the same time, thereby increasing the displacement of the movable mold during adjustment, thereby increasing the time for opening and closing the mold assembly, thereby affecting the efficiency of the injection molding machine in making plastic pallets;

[0006] 2. In the existing injection molding machine, during use, the plastic pallet related materials are introduced into the barrel, the heating component is controlled to heat and melt the materials in the barrel, the drive motor is started to drive the stirring component to stir the materials, and the auger is driven to introduce the molten material into the mold for cooling and molding, thereby realizing the injection molding of the plastic pallet. However, the position of the barrel is fixed, which is not convenient to move with the movement of the mold, thereby hindering the simultaneous position adjustment of the two molds.

[0007] To this end, we provide a plastic pallet injection molding machine to solve the above problems. Utility Model Content

[0008] The utility model aims to provide a plastic pallet injection molding machine, which solves the problems of long opening and closing time of the mold assembly in the existing injection molding machine and hindering the simultaneous position adjustment of two molds due to the fixed position of the material barrel by arranging the mold assembly and the material arrangement assembly.

[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
