DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] like Figure 1 and Figure 2 As shown, the mold mechanism for foam plastic molding processing equipment of the embodiment of the utility model comprises:

[0024] The die 1 comprises a first die wall 11, a second die wall 12 and a first mounting plate 13. The second die wall 12 is located inside the first die wall 11. The first die wall 11, the second die wall 12 and the first mounting plate 13 together form a first steam chamber 31.

[0025] The punch 2 includes a third mold wall 21, a fourth mold wall 22 and a second mounting plate 23. The fourth mold wall 22 is located on the inner side of the third mold wall 21. The third mold wall 21, the fourth mold wall 22 and the second mounting plate 23 together form a second steam chamber 32. The second mold wall 12 and the fourth mold wall 22 together form a mold cavity 33. The first mounting plate 13 is used to connect with the second mounting plate 23.

[0026] Specifically, the first mounting plate 13 is fitted with the opposite side of the second mounting plate 23, and the first mounting plate 13 and the second mounting plate 23 are connected by bolts. At the same time, the thickness of the first mold wall 11, the second mold wall 12, the third mold wall 21 and the fourth mold wall 22 is less than 4 mm, which is conducive to reducing the weight of the mold structure of the foam plastic molding machine.

[0027] In this embodiment, the mold structure is set to include a die 1 and a punch 2, the die 1 is set to include a first mold wall 11, a second mold wall 12 and a first mounting plate 13, and the punch 2 is set to include a third mold wall 21, a fourth mold wall 22 and a second mounting plate 23. Compared with the traditional foam plastic molding machine mold structure including a mold frame, a mold core, a sealing plate and other structures, only two structures, the die 1 and the punch 2, need to be prepared, which is conducive to simplifying the manufacturing process; at the same time, compared with the traditional foam plastic molding machine mold structure, which needs to assemble the mold core, the mold frame and the sealing plate in sequence, the die 1 and the punch 2 can be connected by connecting the first mounting plate 13 and the second mounting plate 23, which is conducive to simplifying the assembly process of the foam plastic molding machine mold structure.

[0028] In addition, filling the first steam chamber 31 and the second steam chamber 32 with steam is beneficial for applying the heat in the steam to the foam plastic material filled in the mold cavity 33, which is beneficial for ensuring the effect of the mold structure of the foam plastic molding machine.

[0029] Alternatively, if Figure 1 and Figure 2 As shown, the first mold wall 11 and the second mold wall 12 are both configured as hemispherical structures, and the third mold wall 21 and the fourth mold wall 22 are both configured as hemispherical structures.

[0030] Specifically, the first mold wall 11 , the second mold wall 12 , the third mold wall 21 , and the fourth mold wall 22 are concentrically arranged.

[0031] In this embodiment, the first mold wall 11, the second mold wall 12, the third mold wall 21 and the fourth mold wall 22 are all set to a hemispherical structure. Since the second mold wall 12 is set inside the first mold wall 11, the first steam chamber 31 is a hemispherical structure. Similarly, the fourth mold wall 22 is set inside the third mold wall 21, and the second steam chamber 32 is a hemispherical structure. Therefore, when the first steam chamber 31 and the second steam chamber 32 are hemispherical structures, it can be ensured that the steam in the first steam chamber 31 and the second steam chamber 32 can act on the foam plastic material filled in the mold cavity 33, and the space between the first steam chamber 31 and the second steam chamber 32 can be reduced, which is conducive to ensuring that the steam acts on the foam plastic material filled in the mold cavity 33 to a greater extent, avoiding steam waste and reducing energy loss.

[0032] Alternatively, if Figure 2 As shown, a first steam port 41 is opened at the upper end of the first mold wall 11 , and the first steam port 41 is connected to the first steam chamber 31 . A second steam port 42 is opened at the upper end of the second mold wall 12 , and the second steam port 42 is connected to the second steam chamber 32 .

[0033] In this embodiment, a first steam port 41 is opened at the upper end of the first mold wall 11, and steam is filled into the first steam chamber 31 through the first steam port 41. A second steam port 42 is opened at the upper end of the second mold wall 12, and steam is filled into the second steam chamber 32 through the second steam port 42. That is, the first steam chamber 31 and the second steam chamber 32 can be inflated through the first steam port 41 and the second steam port 42 at the same time, which is beneficial to quickly heating the foam plastic material filled in the mold cavity 33.

[0034] Alternatively, if Figure 2 As shown, a first exhaust port 43 is formed at the upper end of the first mold wall 11 , and the first exhaust port 43 is connected to the first steam chamber 31 . A second exhaust port 44 is formed at the upper end of the second mold wall 12 , and the second exhaust port 44 is connected to the second steam chamber 32 .

[0035] In this embodiment, a first exhaust port 43 is provided on the first mold wall 11 , and a second exhaust port 44 is provided on the second mold wall 12 , which is beneficial for depressurizing the first steam chamber 31 and the second steam chamber 32 .

[0036] Alternatively, if Figure 2 As shown, a feed inlet 5 is opened in the middle of the first mold wall 11 , and the feed inlet 5 is connected to the mold cavity 33 .

[0037] In this embodiment, a feed inlet 5 is provided in the middle of the first mold wall 11 , and EPS or EPP foam plastic materials can be filled into the mold cavity 33 through the feed inlet 5 .

[0038] Alternatively, if Figure 2 As shown, a first cooling water inlet 61 is opened at the lower end of the first mold wall 11 , and the first cooling water inlet 61 is connected to the first steam chamber 31 . A second cooling water inlet 62 is opened at the lower end of the second mold wall 12 , and the second cooling water inlet 62 is connected to the second steam chamber 32 .

[0039] In this embodiment, a first cooling water inlet 61 is provided on the first mold wall 11, and cooling water is injected into the first steam chamber 31 through the first cooling water inlet 61, so that the product in the mold cavity 33 can be cooled. Similarly, a second cooling water inlet 62 is provided on the second mold wall 12, and cooling water is injected into the second steam chamber 32 through the second cooling water inlet 62, so that the product in the mold cavity 33 can also be cooled. Therefore, by providing the first cooling water inlet 61 at the lower end of the first mold wall 11 and the second cooling water inlet 62 at the lower end of the second mold wall 12, cooling water can be injected into the first steam chamber 31 and the second steam chamber 32 at the same time to cool the product in the mold cavity 33, which is conducive to improving the cooling efficiency.

[0040] Alternatively, if Figure 2As shown, a first drain port 63 is formed at the lower end of the first mold wall 11 , and a second drain port 64 is formed at the lower end of the second mold wall 12 .

[0041] In this embodiment, a first drain port 63 is opened at the lower end of the first mold wall 11, and a second drain port 64 is opened at the lower end of the second mold wall 12. On the one hand, it is beneficial for water to flow in the first steam chamber 31 and the second steam chamber 32 to quickly cool down the product in the mold cavity 33.

[0042] Alternatively, if Figure 2 As shown, a top outlet 7 is provided at the lower end of the first mold wall 11 .

[0043] In this embodiment, an ejection outlet 7 is provided at the lower end of the first mold wall 11. After the foam plastic product is formed, the product can be ejected through the ejection outlet 7, which is conducive to removing the product from the mold structure.

[0044] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
