Description

Technical Field

[0001] This utility model relates to the field of molds, and more specifically, to a casting mold for a circulating pump body. Background Technology

[0002] A mold is a tool used to create shaped products. Different shapes of molds are used to create products of different shapes, such as... Figure 1 The circulating pump body shown is made of metal and has an irregular shape. The internal channels are also irregular. Obviously, it is not feasible to use a transmission machine tool for processing. It needs to be formed by sand core and casting mold, and then the main body after casting is processed to obtain the circulating pump body. However, there is currently no casting mold for the main body of the circulating pump body on the market. Therefore, there is an urgent need for a casting mold that can meet the requirements of the circulating pump body. Utility Model Content

[0003] This invention provides a casting mold for a circulating pump body, aiming to solve the technical problem of casting and forming the circulating pump body.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a casting mold for a circulating pump body, comprising an upper mold plate, a lower mold plate, and a side mold plate. The upper mold plate has an upper forming groove, the lower mold plate has a lower forming groove, and the side mold plate has a side forming groove. The side forming groove extends out of the side mold plate. The upper forming groove, the lower forming groove, and the side forming groove constitute a forming cavity. A forming sand core is provided in the cavity. The forming sand core is assembled from several irregularly shaped sand cores.

[0005] Furthermore, the upper template is provided with an insert, which is used to position the irregular sand core.

[0006] Furthermore, the side template is further provided with a feeding hopper, which is aligned with the side forming groove.

[0007] Furthermore, the lower template is further provided with a base plate, and cooling pipes are provided inside the base plate.

[0008] Furthermore, the upper template and the lower template are further provided with ejector plates, and the ejector plates are provided with a plurality of ejector pins, which can slide through the upper template and the lower template.

[0009] Furthermore, a hydraulic cylinder is further provided on the base plate, and the piston rod of the hydraulic cylinder is connected to the side template.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model relates to a simple and ingeniously designed casting mold for a circulating pump body. It includes an upper mold plate, a lower mold plate, and side mold plates. The upper mold plate has an upper forming groove, the lower mold plate has a lower forming groove, and the side mold plates have side forming grooves. These grooves form a molding cavity, within which a molding sand core is placed. The molding sand core is assembled from several irregularly shaped sand cores. During injection molding, the irregularly shaped sand cores are first assembled and placed in the lower forming groove. The upper and side mold plates are then placed close to the lower mold plate. Molten aluminum is introduced from the side forming grooves, and the mold is rotated to fill the cavity. After cooling and molding, the circulating pump body is formed. The sand cores are then removed from the circulating pump body for further processing to obtain the circulating pump body. This invention fills a technological gap in the domestic market for casting circulating pump bodies. Attached Figure Description

[0030] Example

[0031] Reference Figure 1-6 As shown, this utility model discloses a casting mold for a circulating pump body 70, including an upper mold plate 10, a lower mold plate 20, and a side mold plate 40. The upper mold plate 10 has an upper forming groove 101, the lower mold plate 20 has a lower forming groove 201, and the side mold plate 40 has a side forming groove 402. The side forming groove 402 extends out of the side mold plate 40. The upper forming groove 101, the lower forming groove 201, and the side forming groove 402 constitute a forming cavity. During mold closing and injection molding, the upper mold plate 10, the lower mold plate 20, and the side mold plate 40 are closed, and molten aluminum is injected from the side forming groove 402 into the forming cavity for casting the circulating pump body 70. The lower mold plate 20 is further provided with a base plate 60, and a cooling pipe 601 is provided in the base plate 60. In this embodiment, the cooling pipe 601 is not a traditional large-area cooling forming. The cooling pipe 601 concentrates the cooling of one position of the circulating pump body 70, ensuring that the thinner part of the circulating pump body 70 cools and solidifies first, avoiding deformation when the mold is opened.

[0032] Reference Figure 1-6 As shown, during mold opening, the upper mold plate 10 and the lower mold plate 20 separate, and the side mold plate 40 leaves the lower mold plate 20. The upper mold plate 10 and the lower mold plate 20 are further provided with an ejector plate 30, on which several ejector pins 301 are provided. The ejector pins 301 can slide through the upper mold plate 10 and the lower mold plate 20. After demolding, the main body of the circulating pump body 70 stays on the upper mold plate 10 or the lower mold plate 20. The ejector plate 30 pushes the ejector pins 301 to push the molded circulating pump body 70 out of the lower mold plate 20 or the upper mold plate 10, thereby realizing the demolding of the product.

[0033] Reference Figure 4-6 As shown, a molding sand core 50 is provided inside the mold cavity, and the molding sand core 50 is assembled from several irregularly shaped sand cores 50. Specifically, since the internal pipes of the circulating pump body 70 are irregularly shaped, multiple irregularly shaped sand cores 50 are combined to form the internal pipes of the circulating pump body 70. An insert is provided on the upper template 10, which is used to position the irregularly shaped sand core 50. Before mold closing, the sand core 50 is placed in the lower molding groove 201. After mold closing, the sand core 50 is pressed and fixed by the insert of the upper template 10 to prevent the sand core 50 from moving during the pouring of molten aluminum, which would cause burrs or other defects inside the molded circulating pump body 70 and affect its use.

[0034] Reference Figure 3 As shown, the side template 40 is further provided with a feeding hopper 403, which is aligned with the side forming groove 402. The feeding hopper 403 is used to hold the aluminum liquid, and the aluminum liquid is poured into the cavity from the feeding hopper 403 by swinging the mold, so as to avoid splashing when pouring the aluminum liquid.

[0035] In addition, a hydraulic cylinder 401 is installed on the base plate 60. The piston rod of the hydraulic cylinder 401 is connected to the side template 40. The movement of the side template 40 is controlled by the hydraulic cylinder 401 to realize the closing and opening of the side template 40.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
