[0027] Although compression foaming is a relatively mature process, there are still some problems. For example, most foaming equipment has a complex structure, which is not only complicated and cumbersome to operate, but also can only produce one product at a time, which is inefficient.

[0028] Therefore, the design concept of the present application is to redesign the foaming structure so that it is not only simple in structure and easy to operate, but also can produce multiple products at the same time, thereby improving the foaming efficiency.

[0029] like Figure 1-2As shown, the present application provides a compression molding foaming device, including a machine base 1, on which an upper mold 2, a middle mold 3, a lower mold 4 and an oil cylinder 5 connected to the lower mold 4 are arranged in sequence from top to bottom; an upper mold upper mold cavity 201 is arranged at the bottom of the upper mold 2, and the upper mold upper mold cavity 201 is connected to an upper air inlet and pressurization port 6; a middle mold lower mold cavity 301 is arranged on the upper surface of the middle mold 3, and a middle mold upper mold cavity 302 is arranged at the bottom of the middle mold 3; a lower mold lower mold cavity 404 is arranged on the upper surface of the lower mold 4, and the lower mold lower mold cavity 401 is connected to a lower air inlet and pressurization port 7.

[0030] Among them, the machine base 1 is connected to the column 8, the column 8 is connected to the upper beam 9, the bottom of the upper beam 9 is connected to the top of the upper mold 2; the machine base 1 is threadedly connected to the column 8, the column 8 is threadedly connected to the upper beam 9, and the upper beam 9 is threadedly connected to the upper mold 2.

[0031] The middle mold 3 and the lower mold 4 are slidably connected to the pillars 8 respectively; the pillars 8 serve as a guide for the middle mold 3 and the lower mold 4, and the middle mold 3 and the lower mold 4 can slide freely up and down on the pillars.

[0032] The base 1 is provided with a guide groove 10, which is slidably connected to the middle mold 3. The design of the guide groove 10 restricts the middle mold 3 from sliding downward, which is more conducive to making room for feeding.

[0033] Among them, at least one middle mold 3 is set; if one middle mold 3 is set, the device can produce two products at the same time, and if two are set, the device can produce three products at the same time, and so on. When multiple middle molds 3 are set, corresponding guide grooves 10 should also be set, that is, one middle mold 3 corresponds to one vertical guide groove 10, and the height of each guide groove 10 is different (the top height of each guide groove 10 is the same, and the bottom height is different), that is, each middle mold 3 is limited to a different height, so that the feeding space can be made; note that the corresponding air inlet pressure port should also be set.

[0034] A mold base 11 is provided at the bottom of the lower mold 4 , and the mold base 11 is connected to the oil cylinder 5 ; when the oil cylinder 5 is extended and retracted, the mold base 11 brings the lower mold 4 up and down.

[0035] The upper mold cavity 201 of the upper mold and the lower mold cavity 301 of the middle mold are combined to form an upper mold body, and the upper mold cavity 302 of the middle mold and the lower mold cavity 401 of the lower mold are combined to form a lower mold body; the lower mold cavity 301 of the middle mold and the lower mold cavity 401 are respectively placed with materials.

[0036] The usage steps of the present application are as follows: the material 12 is placed in the middle mold lower mold cavity 301 and the lower mold lower mold cavity 401 respectively, the oil cylinder 5 is started, the oil cylinder 5 extends upward, and the lower mold 4 moves upward accordingly until it is molded with the middle mold 3. After the mold is molded, the oil cylinder continues to move upward. At this time, the lower mold 4 and the middle mold 3 move upward accordingly until the middle mold 3 is molded with the upper mold 2. After the upper, middle and lower molds are molded, the upper air inlet pressure port 6 and the lower air inlet pressure port 7 are pressurized. The thrust generated by the oil cylinder 5 is sufficient to balance and is greater than the force generated by the internal pressure of the mold cavity. After the process time is up, the air is exhausted instantly, and then the oil cylinder 5 is depressurized and returns, and finally the foamed material is taken out.

[0037] The advantages of this application are simple operation, high efficiency, short foaming time, multiple products can be produced by one mold closing, high utilization rate of pressure cavity space, saving nitrogen, low cost, and high molding quality due to cavity foaming.

[0038] Although the present invention has been described in detail with reference to the accompanying drawings and in combination with preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, ordinary technicians in the field can make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions should all be within the scope of the present invention. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present invention, which should all be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
