Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and particularly relates to a secondary ejection safety control structure. Background Art

[0002] In mold manufacturing and injection molding processes, the ejection mechanism is a key part to ensure the smooth ejection of products from the mold. However, with the increasing complexity and diversification of product designs, traditional single-ejection mechanisms can no longer meet all production requirements. Especially when dealing with products with complex shapes and fine structures, single ejection often fails to completely separate the product from the mold, resulting in product damage, mold wear, or reduced production efficiency. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a secondary ejection safety control structure to solve the problem that traditional single-ejection mechanisms can no longer meet all production requirements. Especially when dealing with products with complex shapes and fine structures, single ejection often fails to completely separate the product from the mold, resulting in product damage, mold wear, or reduced production efficiency.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A secondary ejection safety control structure includes an upper die base, an upper backing plate, a stripping back plate, a lower template, and a lower die base. An installation groove is provided between the lower template and the lower die base. An ejection plate is arranged in the installation groove. A compression spring, a guiding post, and an ejection rod are arranged on the ejection plate. The guiding post extends to the lower die base. A limit buckle mechanism is arranged between the ejection plate and the lower template.

[0005] As a further description of the above technical scheme:

[0006] The ejection rod extends into the punch in the lower template.

[0007] As a further description of the above technical scheme:

[0008] The limit buckle mechanism includes a fixed block, a first buckle block, and a second buckle block. The fixed block is connected to the ejection plate. The first buckle block is detachably connected to the lower die base and extends to be connected to the fixed block. The second buckle block is detachably connected to the ejection plate and extends to be connected to the fixed block.

[0009] As a further description of the above technical scheme:

[0010] The fixed block is provided with a first jack and a second jack. The first buckle block is inserted into the first jack, and the second buckle block is inserted into the second jack.

[0011] As a further description of the above technical scheme:

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, an ejector plate is arranged in the installation groove between the lower die base and the lower template, a compression spring is arranged between the ejector plate and the lower template, the ejector plate is limited on the lower die base by a limit buckle machine, and the compression spring is in a stretched state. When the first buckle and the second buckle on the limit buckle machine are disassembled, the ejector plate moves upward as a whole driven by the spring, thereby driving the ejector rod to perform a secondary ejection on the product. This structure performs a secondary ejection operation after the ejector pins in the inner mold of the product complete the primary ejection to ensure that the product is completely separated from the mold, avoid mold damage, and improve production efficiency.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0026] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] Please refer to Figures 1 - 3, the utility model provides a technical solution: a secondary ejection safety control structure, including an upper die base 1, an upper backing plate 2, a stripping back plate 3, a lower template 4 and a lower die base 5. An installation groove 6 is arranged between the lower template 4 and the lower die base 5. An ejection plate 7 is arranged in the installation groove 6. A compression spring 8, a guiding post 9 and an ejection rod 10 are arranged on the ejection plate 7. The guiding post 9 extends to the lower die base 5. A limit buckle mechanism 11 is arranged between the ejection plate 7 and the lower template 4.

[0028] The ejection rod 10 extends into a punch 15 in the lower template 4.

[0029] The limit buckle mechanism 11 includes a fixed block 111, a first buckle block 112 and a second buckle block 113. The fixed block 111 is connected to the ejection plate 7. The first buckle block 112 is detachably connected to the lower die base 5 and extends to be connected to the fixed block 111. The second buckle block 113 is detachably connected to the ejection plate 7 and extends to be connected to the fixed block 111.

[0030] A first jack 12 and a second jack 13 are arranged on the fixed block 111. The first buckle block 112 is inserted into the first jack 12, and the second buckle block 113 is inserted into the second jack 13.

[0031] When secondary ejection is required, only the first buckle block needs to be disassembled and taken out from the first jack, and the second buckle block is disassembled.

[0032] And taken out from the second jack, then the ejection plate will be unconstrained, and the product can be normally ejected for the second time.

[0033] The compression spring 8 is sleeved on a guiding column 14, and the compression spring 8 is connected between the ejection plate 7 and the lower template 4. This can prevent the compression spring from shifting without guidance during reset, which affects the accurate ejection of the product by the ejection rod.

[0034] Working principle: By arranging an ejection plate in the installation groove between the lower die base and the lower template, a compression spring is arranged between the ejection plate and the lower template. The ejection plate is limited on the lower die base by the limit buckle mechanism, and the compression spring is in a stretched state. When the first buckle block and the second buckle block on the limit buckle mechanism are disassembled, the ejection plate moves upward as a whole driven by the spring, thereby driving the ejection rod to perform secondary ejection on the product. This structure performs a secondary ejection operation after the ejector pin in the inner mold of the product completes the primary ejection, so as to ensure that the product is completely separated from the mold, avoid mold damage, and improve production efficiency.

[0035] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
