Description

Technical Field

[0001] This utility model relates to the field of mold fixing technology, and more specifically, to a mold pressing structure. Background Technology

[0002] The installation of stamping dies is a crucial step in stamping parts production and die debugging, and its importance is particularly evident in the compact multi-station progressive dies. Traditional press-fitting structures are described in the attached diagram. Figure 5 As shown, it includes a mold, a bottom fixing plate, and side fixing plates; the mold is circular in shape and its bottom surface is integrally formed with a mounting base of a large diameter; during use, the mold mounting base is first bolted to the bottom fixing plate, and then the two side fixing plates are pressed down and fixed to the surface of the mold mounting base respectively, and finally the two side fixing plates are bolted to the bottom fixing plate.

[0003] This type of press-fitting structure, which uses symmetrical press-fitting at the front and back of the mold, can cause a series of problems due to the narrow working space. Hands and tools such as wrenches cannot reach or touch some bolts, resulting in a significant decrease in debugging efficiency and a high risk of accidents such as hand injuries. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art above, and then to propose a mold pressing structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A mold pressing structure includes a mold, a bottom fixing plate and a side fixing plate; an annular groove is formed on the outer side of the mold and is bolted to the bottom fixing plate, and a side fixing plate is bolted to the bottom fixing plate. There is only one side fixing plate and it is provided with a slot that matches the shape of the annular groove and is used to enter the annular groove.

[0006] Furthermore, in the above scheme, after the mold is installed, the distance between its outer side and the vertical extension surface of the outer side of the bottom fixing plate does not exceed 2cm.

[0007] Furthermore, the mold height is consistent with that of a traditional mold, and the inner diameter of the annular groove is consistent with that of a traditional mold outer diameter.

[0008] Furthermore, in the above solution, the side fixing plate is flat, and its thickness is consistent with the height of the annular groove.

[0009] Furthermore, in the above solution, after the slot mates with the annular groove, the side fixing plate and the bottom fixing plate remain horizontal, and there is a gap between them.

[0010] Furthermore, the above solution includes a protrusion at the bottom of the side fixing plate that contacts the bottom fixing plate, thereby improving the stability of the installation.

[0011] Furthermore, the above solution includes a spring between the bottom fixing plate and the side fixing plate, with the spring sleeved outside the connecting bolts between the bottom fixing plate and the side fixing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model innovatively adopts a matching structure of a single side fixing plate and an outer annular groove of the mold to replace the traditional symmetrical pressing. It eliminates the large-diameter mounting seat integrally formed at the bottom of the mold and directly bolts the mold to the bottom fixing plate. This not only greatly expands the working space by reducing the pressing components on one side, solving the problem that hands and tools cannot reach the bolts, improving debugging efficiency and avoiding safety accidents such as hand pinching, but also reduces the overall space occupation with a compact design to adapt to compact working conditions such as multi-station continuous molds. At the same time, the matching docking of the annular groove and slot and the double bolt connection form a stable fixing system, achieving circumferential full limiting and rigid fixing, ensuring the structural stability and accuracy of mold pressing, and effectively solving the contradiction between space and stability that is difficult to achieve in traditional solutions.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: A pressing structure for a mold, see attached. Figure 1 - Appendix Figure 3As shown, it includes a mold 1, a bottom fixing plate 2, and a side fixing plate 3; wherein, an annular groove 11 is formed on the outer side of the mold 1 and is bolted to the bottom fixing plate 2, and after installation, the distance between the outer side of the mold 1 and the vertical extension surface of the outer side of the bottom fixing plate 2 does not exceed 2cm; in addition, the bottom fixing plate 2 is bolted to the side fixing plate 3, and there is only one side fixing plate 3, which is provided with a slot 31 that matches the shape of the annular groove 11 and is used to enter the annular groove 11.

[0015] In its implementation, this solution replaces the traditional symmetrical press-fitting with a single side fixing plate 3 and an annular groove 11. Structurally, it eliminates the large-diameter mounting base integrally formed at the bottom of the mold 1, replacing it with an annular groove 11 on the outside of the mold 1, which is directly bolted to the bottom fixing plate 2. At the same time, the distance between the outer side of the mounting base of the mold 1 and the outer side of the bottom fixing plate 2 is controlled to be ≤2cm to reduce space occupation. The side fixing plate 3 is then fixed by connecting the slot 31 of the side fixing plate 3 to the annular groove 11 and bolting the side fixing plate 3 to the bottom fixing plate 2. Compared with the traditional solution, the single side fixing plate 3 reduces the press-fitting components on one side, greatly expands the working space, and solves the problem that hands and tools cannot reach the bolts. This improves debugging efficiency and avoids safety accidents such as hand pinching. Moreover, the compact spacing design and the positioning method of the annular groove 11 can also ensure the stability of the mold 1, making it particularly suitable for multi-station continuous mold scenarios with tight space.

[0016] For the above scheme, please refer to the appendix for details. Figure 2 As shown, the height of mold 1 is consistent with that of traditional mold, and the inner diameter of annular groove 11 is consistent with that of traditional mold. This eliminates the need to adjust the adaptation dimensions of existing production equipment during implementation, reducing modification costs. At the same time, the compact spacing design and positioning of annular groove 11 ensure the stability of mold 1, perfectly adapting to multi-station continuous mold scenarios with limited space.

[0017] For the above scheme, please refer to the appendix for details. Figure 3 As shown, the side fixing plate 3 is flat and its thickness is consistent with the height of the annular groove 11, which can ensure the stable clamping of the mold 1 and prevent loosening. When the slot 31 is connected to the annular groove 11, the side fixing plate 3 and the bottom fixing plate 2 remain horizontal and there is a gap between them, which further optimizes the working space and facilitates the insertion of tools.

[0018] For the above scheme, please refer to the appendix for details. Figure 3 As shown, the bottom of the side fixing plate 3 is provided with a protrusion 32 that contacts the bottom fixing plate 2, so as to improve the stability of the installation.

[0019] For the above scheme, please refer to the appendix. Figure 4As shown, a spring 4 is provided between the bottom fixing plate 2 and the side fixing plate 3. The spring 4 is sleeved on the outside of the connecting bolts of the bottom fixing plate 2 and the side fixing plate 3. During implementation, the spring 4 can provide a continuous elastic preload to counteract the vibration during the stamping operation, prevent the bolts from loosening and causing the mold 1 to shift, and improve the fixing reliability.
