Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a side mold structure for producing two molds in one piece. Background Technology

[0002] In the casting industry, molds that produce two products in a single mold are widely used to improve production efficiency. This requires the side molds to have a larger span and dimensions. Currently, such molds use the traditional one-piece side mold structure. As the size of the side mold increases, the uneven cooling rates of different parts during operation lead to more significant temperature differences, resulting in a sharp increase in internal thermal stress and making it highly susceptible to overall warping deformation. This deformation affects the accuracy of both cavities simultaneously, causing a pair of products to have out-of-tolerance dimensions or even be scrapped, making it difficult to guarantee a high yield rate. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a side mold structure with one mold for producing two molds.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses a side mold structure for a single-outlet mold, comprising two modules. Each module includes a forming surface, a connecting surface, a mating surface, a connecting surface, and an outer end surface. The connecting surface and the mating surface are located at opposite ends of the forming surface. One end of the connecting surface is connected to the connecting surface, and the other end of the connecting surface is connected to the outer end surface. The end of the outer end surface furthest from the connecting surface is connected to the mating surface. The mating surfaces of the two modules fit together. A connecting plate is provided between the two modules, and the connecting plate is fixedly connected to the two modules by fixing bolts.

[0006] Furthermore, there are two connecting plates, and two connecting slots are provided between the two modules. The two connecting plates are respectively installed in the two connecting slots.

[0007] Furthermore, the two connecting slots are arranged correspondingly, with one connecting slot located on one side of the outer end face and the other connecting slot located on one side of the connecting surface.

[0008] Furthermore, a mounting groove 1 is provided at the connection between the outer end face and the mating surface, and a mounting groove 2 is provided at the connection between the mating surface and the connecting surface. The two mounting grooves 1 and 2 on the two modules are spliced ​​together to form a connecting groove.

[0009] Furthermore, a heat dissipation cavity is provided inside the module, and an opening is provided on the mating surface.

[0010] Furthermore, several heat dissipation holes are provided on the outer end face, and the heat dissipation holes are connected to the heat dissipation cavity.

[0011] The beneficial effects of this utility model are: the one-piece large side mold is divided into two small modules and spliced ​​together by connecting plates, the temperature gradient inside each module will be reduced; the two modules are no longer a rigid whole, which significantly reduces the overall warping deformation caused by uneven temperature.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-4 As shown, a side mold structure with one mold for two molds includes two modules 1. Module 1 includes a forming surface 2, a connecting surface 10, a mating surface 12, a docking surface 5, and an outer end surface 3. The connecting surface 10 and the mating surface 12 are located at opposite ends of the forming surface 2. One end of the docking surface 5 is connected to the connecting surface 10, and the other end of the docking surface 5 is connected to the outer end surface 3. The end of the outer end surface 3 away from the docking surface 5 is connected to the mating surface 12. The docking surfaces 5 of the two modules 1 fit together. A connecting plate 8 is provided between the two modules 1, and the connecting plate 8 is fixedly connected to the two modules 1 by fixing bolts 9. By dividing a large side mold into two smaller modules 1, the temperature gradient inside each module 1 will decrease, resulting in less deformation. At the same time, the two modules 1 are no longer a rigid whole; they have a certain degree of relative freedom of movement and can partially expand and contract independently, thereby greatly reducing the internal thermal stress caused by the overall mutual restraint.

[0019] There are two connecting plates 8, and two connecting slots are provided between the two modules 1. The two connecting slots are arranged in a front-to-back manner, with one connecting slot located on one side of the outer end face 3 and the other connecting slot located on one side of the connecting surface 10. The two connecting plates 8 are respectively installed in the two connecting slots.

[0020] A mounting groove 7 is provided at the connection between the outer end face 3 and the mating surface 5, and a mounting groove 13 is provided at the connection between the mating surface 5 and the connecting surface 10. After the mating surfaces 5 of the two modules 1 are fitted together, the two mounting grooves 7 and the two mounting grooves 13 are spliced ​​together to form a connecting groove. Threaded holes are provided on the bottom walls of both mounting groove 7 and mounting groove 13. Blind holes corresponding to the positions of the threaded holes are provided on the connecting plate 8. Fixing bolts 9 pass through the blind holes on the connecting plate 8 and are screwed into the corresponding threaded holes, thereby fixing the connecting plate 8 to the module 1, and thus fixing the two modules 1 together. At the same time, the side wall of the connecting plate 8 fits against the side wall of the connecting groove.

[0021] A heat dissipation cavity 11 is provided inside the module 1, and an opening 6 is provided on the mating surface 5, so that the heat dissipation cavities 11 in the two modules 1 are connected and can dissipate heat together, so that the temperature of the two modules 1 is relatively consistent.

[0022] Several heat dissipation holes 4 are provided on the outer end face 3. The heat dissipation holes 4 are connected to the heat dissipation cavity 11. The heat dissipation holes 4 connect the heat dissipation cavity 11 to the outside, which can dissipate heat more effectively.

[0023] The connecting plate 8, which is installed in the connecting groove formed by splicing two mounting slots 13, is closer to the forming surface 2 and receives more heat transfer, making it easier for the temperature to rise. By setting it as a metal heat sink with good thermal conductivity, it can effectively prevent heat from pushing and causing deformation at this point.

[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
