[0029] The following is combined with Figure 1-9 , the embodiments of the utility model are further described in detail.

[0030] A plastic mold 1 for a solid wood bed joint rubber sleeve, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it includes an upper mold 2, a mold core 3, a lower mold 4 and a demoulding device 5. A plurality of mold cavities for molding products 6 are arranged between the upper mold 2 and the lower mold 4, and the mold core 3 is used for injection molding to form products 6. A plurality of core seats 31 are arranged at intervals on one side of the mold core 3, and each core seat 31 is used to form a product 6. The core seat 31 includes a base 311 connected to the side of the mold core 3, a sleeve seat 312 arranged on the base 311 away from the mold core 3, and two fastener seats 313 arranged on the side of the sleeve seat 312 away from the base 311. The lower mold 4 includes a molding plate 41, and the molding plate 41 is arranged on the side of the mold core 3 facing the upper mold 2. A through molding groove 411 is arranged on the molding plate 41 corresponding to the position of the core seat 31, a partition seat 412 is arranged between two adjacent molding grooves 411, and a partition groove for forming products 6 is arranged between the partition seat 412 and the side of the core seat 31. The demoulding device 5 is used to demould multiple products 6 from the core seat 31 at the same time.

[0031] The mold core 3, the molding plate 41 and the upper mold 2 enclose multiple mold cavities, and multiple products 6 are injection molded at the same time. The core seat 31 and the side of the mold core 3 are arranged vertically, and with the cooperation of the molding plate 41 and the upper mold 2, the products 6 are arranged in a vertical arrangement, which increases the number of products 6 produced and improves the production efficiency.

[0032] In this embodiment, please refer to Figure 5 , Fig. 9 The side of the separator 412 facing the core seat 31 is provided with a pattern core 414 for matching the pattern on the side of the product 6, so that it can better help the product 6 to separate from the mold core 3 during demolding, improve the demolding efficiency, and save costs. The pattern core 414 on the separator 412 is not limited here, and the style of the pattern core 414 can be adapted according to the actual needs of the product.

[0033] For easy demoulding, please refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 The demoulding device 5 includes a push plate 51 and a plurality of ejector pins 52. The push plate 51 is arranged on the side of the mold core 3 away from the molding plate 41. At least one through pinhole 314 is arranged on the core seat 31. A plurality of ejector pins 52 are arranged on the molding plate 41 at intervals corresponding to the pinholes 314, and each ejector pin 52 corresponds to a pinhole 314. One end of the ejector pin 52 is fixed on the molding plate 41, and the other end of the ejector pin 52 is arranged in the corresponding ejector pin 52. When the product 6 is separated from the core seat 31, the push plate 51 is closest to the molding plate 41, and the ejector pin 52 passes through the core seat 31. The product 6 can be better separated from the mold and fall off during the production process, and the demoulding effect is better.

[0034] A plurality of rows of core seats 31 are arranged side by side on the molding plate 41 , and a plurality of guide holes 413 are arranged between two adjacent rows of core seats 31 . The other ends of some ejector pins 52 pass through the corresponding guide holes 413 , thereby improving the stability and efficiency of demoulding.

[0035] The lower mold 4 further includes a fixing plate 42, which is disposed on the side of the mold core 3 facing away from the molding plate 41, and is used to cooperate with the molding plate 41 to fix the mold core 3. The upper end of the ejector pin 52 can also be placed in the fixing plate 42 to prevent the ejector pin 52 from being misplaced and affecting the efficiency of demoulding.

[0036] The demoulding device 5 also includes a plurality of guide rods 53, one end of which is fixed on the push plate 51, and the other end of the guide rod 53 sequentially passes through the mold core 3 and the molding plate 41 and is fixedly connected to the upper mold 2, and is slidably connected to the mold core 3 and the molding plate 41, thereby improving the stability of the movement of the push plate 51 and the ejector pin 52.

[0037] Before demoulding, the pins of the product 6 are separated from the pin holder 313 by vacuum forced separation, so that when the pin position is separated from the mold core 3, other accessories such as a slanted ejector or a slider are no longer needed to assist in separating the undercut position of the mold core 3, making the mold more convenient to use during production. Then, a secondary demoulding method of a push plate 51 plus an ejector pin 52 is adopted, so that the mold can better separate the product 6 from the mold during production, and the demoulding effect is better. Pushing the push plate 51 drives the ejector pin 52 to move toward the upper mold 2, and under the pushing action of the guide rod 53, the upper mold 2 is automatically separated from the mold core 3 and the molding plate 41. When the push plate 51 moves to the set position, the ejector pin 52 ejects the product 6, so that the product 6 is separated from the core holder 31 and falls off the mold core 3, so as to achieve simultaneous demoulding of multiple products 6, which significantly improves the demoulding efficiency.

[0038] Please refer to Figure 8 When the upper mold 2 and the lower mold 4 are manually separated, the upper mold 2 and the lower mold 4 can be fixedly connected by a plurality of fixing strips 54 .

[0039] In order to realize automatic demoulding and improve demoulding efficiency. Figure 1 , Figure 2 , Figure 3 In another embodiment, the demoulding device 5 further includes a mounting plate 55, a plurality of guide rails 56 and a limit slider 57 matched with the guide rails 56. The mounting plate 55 is arranged on the side of the push plate 51 away from the mold core 3, and at least one guide rail 56 is arranged on both sides of the mounting plate 55. One end of the guide rail 56 is fixedly connected to the side of the upper mold 2, and the other end of the guide rail 56 is located on the side of the mounting plate 55. The limit slider 57 is arranged on the side of the molding plate 41, and the limit slider 57 is slidably connected to the guide rail 56. The mounting plate 55 is threadedly connected to the mold core 3 and the molding plate 41 by screws to drive the molding plate 41 and the mold core 3 to move together. When demoulding, the limit slider 57 is located at the end of the guide rail 56 away from the upper mold 2. Automatic demoulding is achieved and the efficiency of demoulding is improved. The mounting plate 55 and the upper mold 2 are respectively connected to an external driving mechanism.

[0040] The guide rail 56 is provided with a slide groove 561 along its length direction, and the limiting slider 57 is provided as a columnar structure. The limiting slider 57 is slidably provided in the slide groove 561 on the side away from the molding plate 41, thereby improving the stability of the sliding structure connection and saving costs.

[0041] Wherein, two guide rails 56 are arranged on both sides of the mounting plate 55, which can improve the stability of operation and ensure the balance. In order to ensure that all the products 6 are demoulded, the push plate 51 performs two forward push actions.

[0042] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
