Description

Technical Field

[0001] The present application relates to the technical field of molds, and in particular to a universal mold structure and a composite mold. Background Art

[0002] A common injection mold typically consists of an upper mold and a lower mold, and some injection molded products also include a core mold. The upper and lower molds serve as the concave and convex molds, respectively, and together they form the mold cavity. The rubber compound is injected into this cavity and solidified to form the product. Injection molds are also equipped with ejector pins. Once injection is complete and the mold is opened, these pins eject the product from the mold cavity, allowing it to be released from the mold.

[0003] Because the mold cavity inside an injection mold is difficult to adjust, a typical mold set is typically used to produce only one product. Changing products requires replacing the entire mold set. Furthermore, since an injection mold set can contain anywhere from dozens to hundreds of parts, its design and production costs are high. In large-scale production, mold costs have a minimal impact on product costs; however, in small-batch production, the cost of replacing the mold can significantly impact production costs.

[0004] Therefore, how to improve the versatility and flexibility of molds without increasing excessive complexity and cost, thereby reducing the cost of small-batch production, has become an important issue facing the current mold manufacturing field. Utility Model Content

This design allows the ejector assembly to automatically reset and quickly respond when needed, pushing the adjustment plate and ejector pins for demolding.

[0013] Preferably, the adjustment plate is detachably connected to the push rod.

[0014] By adopting the above technical solution, the installation and disassembly of the adjustment plate are facilitated, and the flexibility and maintainability of the mold are further improved.

[0015] Preferably, an adjusting member is further provided on the base seat, the adjusting member is screwed to the base seat, and the adjusting member abuts against the end of the spring.

[0016] By adopting the above technical solution, during the use of the mold, the thrust of the ejection assembly can be adjusted by rotating the adjustment part according to the characteristics of the product to be demoulded and the difficulty of demoulding, so as to ensure smooth demoulding and avoid damage to the product.

[0017] Preferably, a guide column is provided on the side of the base seat facing the groove plate, and a guide hole that slides with the guide column is opened on the adjustment plate.

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] This embodiment discloses a universal mold structure, referring to Figure 1 and Figure 2 The mold assembly comprises a base 1, a push assembly 2, an adjustment plate 3, a replaceable groove plate 4, and ejector pins 5. The groove plate 4 is removably connected to the base 1 via bolts and other fasteners, allowing for easy replacement of the groove plate 4 according to production needs. The adjustment plate 3 is positioned between the base 1 and the groove plate 4. The ejector pins 5 are inserted through the groove plate 4 and connected to the adjustment plate 3 to eject the finished product from the mold. The push assembly 2 is mounted on the base 1 and pushes the adjustment plate 3 to drive the ejector pins 5 for demolding.

[0036] Therefore, when replacing the injection mold, the appropriate groove plate 4 can be selected based on the desired product and installed on the base 1. The push assembly 2 then pushes the adjustment plate 3, which in turn drives the ejector pins 5 for demolding. Because the groove plate 4 is removable and replaceable, the mold structure can adapt to the production needs of a variety of different products, significantly reducing production costs for small batches. Furthermore, because different groove plates 4 utilize different ejector pin distribution patterns, the ejector pins are abutted against the adjustment plate 3, allowing the adjustment plate 3 to push all ejector pins, thereby ensuring the proper functioning of the mold.

[0037] Specifically, to facilitate the placement and stable operation of the ejection assembly 2, the base 1 is provided with a cavity within which the ejection assembly 2 is disposed. The ejection assembly 2 comprises a spring 21, a push plate 22, and a push rod 23. The push plate 22 is movably disposed within the cavity. One end of the push rod 23 is connected to the push plate 22, while the other end passes through the base 1 and is connected to the adjustment plate 3. The spring 21 is positioned on the side of the push plate 22 facing away from the push rod 23 and is connected to the push plate 22, thereby providing continuous thrust to the push plate 22. This design enables the ejection assembly 2 to automatically reset and quickly respond when needed, pushing the adjustment plate 3 and ejector pin 5 for demolding.

[0038] The connection between the adjustment plate 3 and the push rod 23 is a detachable connection, such as a screw connection or a plug connection, etc. This design facilitates the installation and removal of the adjustment plate 3, further improving the flexibility and maintainability of the mold.

[0039] The base 1 is also equipped with an adjustment member 11, which is threaded onto the base 1 and abuts the end of the spring 21. Rotating the adjustment member 11 changes the amount of compression applied to the spring 21, thereby adjusting the thrust of the ejection assembly 2. This design allows the mold to adapt to varying demolding force requirements, improving its applicability and flexibility.

[0040] Reference Figure 3 and Figure 4Furthermore, a guide column 12 is provided on the side of the base seat 1 facing the groove plate 4, and a guide hole 31 is provided on the adjustment plate 3 to slide with the guide column 12 to improve the stability of the adjustment rod during movement.

[0041] In order to facilitate the disassembly and assembly of the profiled groove plate 4, a mold frame 6 is provided between the base 1 and the profiled groove plate 4. The profiled groove plate 4, the mold frame 6 and the base 1 are connected by connecting bolts 7, and the connecting bolts 7 pass through the profiled groove plate 4, the mold frame 6 and the base 1 at the same time, thereby ensuring the stability of the connection.

[0042] Furthermore, the base 1 includes a top plate 13, a bottom plate 14 and a side plate 15, and the connecting bolts pass through the top plate, the bottom plate 14 and the side plate 15 to achieve relative fixation of the three. Therefore, the main components of the universal mold structure can be connected into one through the connecting bolts 7.

[0043] The embodiment of the present application also discloses a composite mold using the above-mentioned universal mold structure. Specifically, the above-mentioned universal mold structure serves as an upper mold, and a lower mold is also provided. The upper mold and the lower mold cooperate to form a complete set of injection molds.

[0044] When changing the processed product, only the lower mold and the groove plate 4 need to be replaced. Therefore, the composite mold has high flexibility and applicability, can meet the processing requirements of a variety of different products, and helps to reduce production costs.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
