Description

Technical Field

[0001] This utility model relates to the field of foam production, and in particular to a support plate for a foam plastic molding machine. Background Technology

[0002] Foam plastic molding machines are key equipment in the plastics processing industry, widely used in the production of various types of foam plastic products, such as EPS, EPP, and EPE. As industrial production demands for efficiency and precision continue to increase, the design and manufacturing technology of foam plastic molding machines are also constantly improving. Among them, the support plate, as one of the core components of the molding machine, directly affects the stability, molding accuracy, and production efficiency of the equipment.

[0003] However, the existing support plates of foam plastic molding machines still have some shortcomings and areas for improvement in actual use. Most of the existing support plates are in a fixed state, which causes many inconveniences during mold installation and replacement. In addition, the strength of the existing support plates also needs to be improved. Therefore, those skilled in the art provide a support plate for foam plastic molding machines to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a support plate for a foam plastic molding machine. In use, the plate structure can move back and forth inside the frame by rolling between pulleys and slide rails, which is convenient for use during the molding process, saving time and effort. The sliding connection between the two sliders and the first slide groove ensures the stability of the whole during the sliding process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a support plate for a foam plastic molding machine, comprising a frame, a top plate at the upper end of the frame, the two ends of the top plate being fixedly connected to the two inner side walls of the frame, a movable structure being provided at the center of the lower inner wall of the frame below the top plate, a plate structure being provided at the upper end of the movable structure, and a limiting structure being provided at the center of the front and rear side walls of the front and rear side frames of the movable structure.

[0006] The movable structure includes a slide rail, the lower end of which is fixedly connected to the center of the lower inner wall of the frame, and a pulley slidably connected to the upper end of the slide rail. A through groove is provided at the center of one side wall of the plate structure near the lower edge, and the upper end of the pulley is fixedly connected to the lower inner wall of the through groove. Slider blocks are fixedly connected at the center of the lower end face of the plate structure near the front and rear edges, respectively. First sliding grooves are provided on the lower inner walls of the frame below the two sliders, and the side walls of the two sliders are slidably connected to the interiors of the two first sliding grooves. Second sliding grooves are provided at the centers of the front and rear side walls of the frame, and the two limiting structures pass through the two second sliding grooves and lead to the interiors of the two first sliding grooves.

[0007] With the above technical solution, the plate structure can move back and forth inside the frame by rolling between the pulley and the slide rail, which is convenient for use in the molding process, saving time and effort. The sliding connection between the two sliders and the first slide groove can ensure the stability of the whole during the sliding process.

[0008] Furthermore, the plate structure includes a rigid layer, an impact-resistant layer, a high-temperature resistant layer, and a wear-resistant layer. The wear-resistant layer is disposed on one side of the high-temperature resistant layer, the high-temperature resistant layer is disposed on one side of the impact-resistant layer, and the impact-resistant layer is disposed on one side of the rigid layer.

[0009] By using the above technical solutions and setting the plate structure to a multi-layered composite material, the overall performance and service life can be effectively improved.

[0010] Furthermore, the limiting structure includes a first limiting plate, a wing nut is provided at the center of the front sidewall of the first limiting plate, a screw is fixedly connected to the rear end of the wing nut, the rear end of the screw passes through the front sidewall of the first limiting plate and extends to the rear end, and a second limiting plate is threaded to the end of the screw.

[0011] With the above technical solution, during use, the screw is rotated by rotating the wing nut. The other end of the screw passes through the second slide groove and is threadedly connected to the second limiting plate. The side wall of the second limiting plate is fixedly connected to the side wall of the slider. During use, the slider drives the second limiting plate to slide and connect to the inside of the first and second slide grooves respectively. The threaded connection between the screw and the second limiting plate, plus the limitation between the first limiting plate and the side wall of the second slide groove, can fix the adjusted position.

[0012] Furthermore, the lower end face of the frame is fixedly connected to four opposite corners with legs;

[0013] The above technical solutions facilitate overall support.

[0014] Furthermore, the rigid layer, impact-resistant layer, high-temperature resistant layer, and wear-resistant layer are made of aluminum alloy, polyethylene, nanocomposite material, and polyimide, respectively.

[0015] Through the above technical solutions, aluminum alloy has high strength and will not deform during use; polyethylene has good impact resistance and can prevent it from being squeezed during use; nanocomposite materials can ensure that the effects of high temperature are reduced during use; and polyimide can improve the overall wear resistance and extend the overall service life.

[0016] Furthermore, the second limiting plate is fixedly connected to the movable structure;

[0017] The above technical solution allows the second limiting plate to move synchronously by moving the moving structure.

[0018] Furthermore, the first limiting plate and the screw are rotatably connected;

[0019] With the above technical solution, the first limiting plate will not be affected by the rotation of the screw when the screw is rotated.

[0020] This utility model has the following beneficial effects:
