[0002] EPS (Expanded Polystyrene), polystyrene foam, is a light polymer. It is made of polystyrene resin with a foaming agent, heated to soften, and produce gas to form a rigid closed-cell foam plastic; EPP (Expanded polypropy l ene), polypropylene plastic foam material is a high-performance high-crystalline polymer / gas composite material. With its unique and superior performance, it has become the fastest growing environmentally friendly new pressure-resistant buffer insulation material. In the process of changing from raw materials to molded products through molds, the gas needs to be introduced into the liquid or molten plastic particles to produce micropores, which are then expanded by the gas and grow to a certain volume. Finally, the micropore structure is fixed and formed.
[0003] However, since the mold needs to be heated during the process of EPS and EPP foaming into molded products, and the existing molds are large in size, the heat is dissipated to the surroundings during the heating process. Not all the heat is used to heat and mold the product, resulting in high energy consumption. Utility Model Content

[0014] The beneficial effects of the utility model are:
[0015] (1) When the EPS and EPP raw materials are formed into products, steam is input into the steam chamber cavity through the steam inlet, and the steam moves along the contour of the inner wall in the steam chamber cavity. Since the contour of the inner wall is the same as the contour of the product, the heat in the steam can act on the EPS and EPP raw materials to a greater extent along the contour of the inner wall, which is beneficial to reduce heat loss. At the same time, the contour of the outer wall is the same as the contour of the inner wall. The steam chamber cavity space formed by the inner wall and the outer wall is smaller, and it is difficult for steam to dissipate to the surroundings through the outer wall, further reducing heat loss. In addition, the contour of the outer wall is the same as the contour of the inner wall, which can reduce the overall thickness of the die steam chamber and the overall volume of the EPS and EPP foam plastic molding machine mold structure.

[0017] (3) By providing a plurality of compressed air inlets on the first outer vertical plate and / or the third outer vertical plate, more compressed air can be input through the plurality of compressed air inlets at the same time, thereby accelerating the speed of generating micropores in the EPS and EPP foam plastic products, which is beneficial to accelerating the preparation of EPS and EPP foam plastic products. At the same time, the first outer vertical plate and the third outer vertical plate on which the plurality of compressed air inlets are evenly distributed can evenly input compressed air to each part of the EPS and EPP foam plastic products, thereby ensuring the uniformity of the distribution of micropores in the EPS and EPP foam plastic products, thereby ensuring the product quality of the EPS and EPP foam plastic products.

[0022] The utility model establishes an XY axis coordinate system, wherein the positive direction of the X axis is the front, the negative direction of the X axis is the back, the positive direction of the Y axis is the top, and the negative direction of the Y axis is the bottom.
[0023] like Figure 1 and Figure 2As shown, the embodiment of the utility model is a high-efficiency and energy-saving EPS and EPP foam plastic molding machine mold structure. It includes:
[0024] Punch steam chamber 1;
[0025] The die steam chamber 2 includes an inner wall 21 and an outer wall 22. The inner wall 21 is located on the side close to the punch steam chamber 1. A product 5 is arranged between the inner wall 21 and the punch steam chamber 1. The contour of the inner wall 21 is the same as the contour of the product 5. The outer wall 22 is located on the side away from the punch steam chamber 1. The inner wall 21 and the outer wall 22 together form a steam chamber cavity 3. The contour of the outer wall 22 is the same as the contour of the inner wall 21. A steam inlet 41 connected to the steam chamber cavity 3 is opened on the outer wall 22.
[0026] Specifically, product 5 is EPS or EPP foam plastic product.
[0027] In this embodiment, during the EPS and EPP foam plastic molding process, the die steam chamber 2 and the punch steam chamber 1 are closed together to squeeze the EPS and EPP raw materials between the die steam chamber 2 and the punch steam chamber 1 to form a product 5, and steam is input into the steam chamber cavity 3 through the steam inlet 41 to heat the EPS and EPP raw materials.
[0028] In summary, when the EPS and EPP raw materials are formed into the product 5, steam is input into the steam chamber cavity 3 through the steam inlet 41, and the steam moves along the contour of the inner wall 21 in the steam chamber cavity 3. Since the contour of the inner wall 21 is the same as the contour of the product 5, the heat in the steam can act on the EPS and EPP raw materials to a greater extent along the contour of the inner wall 21, which is conducive to reducing heat loss. At the same time, the contour of the outer wall 22 is the same as the contour of the inner wall 21. The steam chamber cavity 3 formed by the inner wall 21 and the outer wall 22 is small, and it is difficult for steam to dissipate to the surroundings through the outer wall 22, further reducing heat loss. In addition, the contour of the outer wall 22 is the same as the contour of the inner wall 21, which can reduce the overall thickness of the die steam chamber 2 and the overall volume of the EPS and EPP foam plastic molding machine mold structure. The die steam chamber 2 is composed of the inner wall 21 and the outer wall 22, which can simplify the structure of the die steam chamber 2 and reduce the weight of the EPS and EPP foam plastic molding machine mold structure, which is conducive to reducing the energy consumption of driving the die steam chamber 2.
