Description

Technical Field

[0001] This utility model relates to the field of mold equipment technology, and in particular to a die-casting mold. Background Technology

[0002] In the die-casting production process, mold opening is a critical step. Currently, traditional mold opening methods have certain limitations. For example, relying solely on the opening force of the die-casting machine can easily lead to problems such as difficulty in opening complex, large, or sticky molds, accelerated mold wear, and product damage, affecting production efficiency and product quality. Therefore, it is necessary to design an auxiliary device for opening die-casting molds to solve the problem of existing die-casting molds being unable to open. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a die-casting mold to solve the problems of difficult mold opening and easy damage to products in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides a die-casting mold, including a fixed mold and a movable mold that cooperates with the fixed mold. The fixed mold has multiple mounting holes, and each mounting hole has an auxiliary mold opening device. The auxiliary mold opening device includes a base, which is embedded in the mounting hole. The base includes a guide post extending vertically upward, and the guide post does not protrude from the mounting hole. A spring is sleeved on the guide post, and the top of the spring protrudes from the mounting hole by a set height.

[0005] Furthermore, the top of the guide post is provided with a pressure block, the bottom surface of the pressure block abuts against the top of the spring, the pressure block protrudes from the mounting hole by a set height, and the bottom of the pressure block is provided with a guide groove extending in the vertical direction, and the guide post is slidably embedded in the guide groove.

[0006] Furthermore, the top of the pressure block is provided with a mounting groove, and the bottom wall of the mounting groove is provided with a connecting through hole. The first end of the connecting screw passes through the connecting through hole and extends into the guide groove and is threadedly connected to the guide post. The second end of the connecting screw is provided with a limiting flange, which is embedded in the mounting groove. The diameter of the limiting flange is larger than the diameter of the connecting through hole, and the diameter of the connecting through hole is larger than the diameter of the connecting screw.

[0007] Furthermore, the spring is a disc spring.

[0008] Furthermore, the positioning mold is provided with four mounting holes, and the auxiliary mold opening device is provided in each of the four mounting holes.

[0009] As described above, the die-casting mold of this utility model has the following beneficial effects: During operation, when the fixed mold and the moving mold are in the closed state, the top of the spring provided on the fixed mold protrudes beyond the set height of the mounting hole, that is, protrudes beyond the set height of the surface of the fixed mold. Therefore, after the moving mold and the fixed mold are closed, the spring is compressed and stores energy. When the mold opens, as the moving mold separates from the fixed mold, the spring releases the stored energy and applies a pushing force to the moving mold, thereby assisting the die-casting machine in opening the mold smoothly. Therefore, compared with the prior art, the die-casting mold of this utility model can effectively assist the opening action of the die-casting mold by setting the aforementioned auxiliary mold-opening device on the fixed mold, thereby effectively solving the problem of the mold not being able to open in existing die-casting machines, thus improving production efficiency and solving the product quality defects caused by the mold not being able to open.

[0026] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Please see Figures 1 to 4 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0030] This utility model provides a die-casting mold, such as Figures 1 to 4As shown, the die-casting mold includes a fixed mold 10 and a movable mold 20 that cooperates with the fixed mold 10. The fixed mold 10 is provided with multiple mounting holes, and each mounting hole is provided with an auxiliary mold opening device 11. Specifically, the auxiliary mold opening device 11 includes a base 110, which is embedded in the mounting hole. The base 110 includes a guide post 1101 extending vertically upward, and the guide post 1101 does not protrude from the mounting hole. A spring 111 is sleeved on the guide post 1101, and the top of the spring 111 protrudes from the mounting hole by a set height.

[0031] The beneficial effects of this die-casting mold are as follows: During operation, when the fixed mold 10 and the moving mold 20 are in the closed state, the top of the spring 111 provided on the fixed mold 10 protrudes beyond the set height of the mounting hole, that is, protrudes beyond the set height of the surface of the fixed mold 10. Therefore, after the moving mold 20 and the fixed mold 10 are closed, the spring 111 is compressed and stores energy. When the mold opens, as the moving mold 20 separates from the fixed mold 10, the spring 111 releases the stored energy and applies a pushing force to the moving mold 20, thereby assisting the die-casting machine in opening the mold smoothly. Therefore, compared with the prior art, the die-casting mold of this invention can effectively assist the opening action of the die-casting mold by setting the aforementioned auxiliary mold-opening device on the fixed mold, thereby effectively solving the problem of the mold not being able to open in existing die-casting machines, thus improving production efficiency and solving the product quality defects caused by the mold not being able to open.

[0032] Preferably, in order to improve the mold opening effect of the auxiliary mold opening device 11, such as Figure 2 As shown, in this embodiment, the positioning mold 10 is provided with four mounting holes, and the auxiliary mold opening device 11 is provided in each of the four mounting holes.

[0033] Preferably, in this embodiment, the spring 111 is a disc spring, which has a compact structure and strong load-bearing capacity.

[0034] Furthermore, such as Figure 4As shown, in this embodiment, the top of the guide post 1101 is provided with a pressure block 112. The bottom surface of the pressure block 112 abuts against the top of the spring 111. Specifically, the pressure block 112 protrudes from the mounting hole by a set height, and the bottom of the pressure block 112 is provided with a guide groove 1121 extending in the vertical direction. The guide post 1101 is slidably embedded in the guide groove 1121. With this configuration, when the moving mold 20 and the fixed mold 10 of the mold are closed, the moving mold 20 will press down on the pressure block 112 and move together, thereby causing the pressure block 112 to compress the spring 111. When the pressure block 112 compresses the spring 111 and moves, since the guide post 1101 is slidably embedded in the guide groove 1121, the pressure block 112 will be guided by the guide post 1101 to ensure that its movement does not deviate, thereby ensuring the smoothness of the compression of the spring 111.

[0035] Furthermore, to ensure the stability of the connection between the pressure block 112, the guide post 1101, and the spring 111, such as Figure 4 As shown, in this embodiment, the top of the pressure block 112 is provided with a mounting groove 1122, and the bottom wall of the mounting groove 1122 is provided with a connecting through hole. The first end of the connecting screw 12 passes through the connecting through hole and extends into the guide groove 1121 and is threadedly connected to the guide post 1101. The second end of the connecting screw 12 is provided with a limiting flange 120, which is embedded in the mounting groove 1122. Specifically, the diameter of the limiting flange 120 is larger than the diameter of the connecting through hole, and the diameter of the connecting through hole is larger than the diameter of the connecting screw 12. With this configuration, the moving mold 20 will press down on the pressure block 112 and move together. When the pressure block 112 compresses the spring 111, since the diameter of the connecting through hole on the pressure block 112 is larger than the diameter of the connecting screw 12, the pressure block 12 will move relative to the connecting screw 12. The pressure block 12 is fixed relative to the guide post 1101 by the threaded connection of the first end of the connecting screw 12 to the guide post 1101 and the limiting flange 120 at the second end. This ensures that the pressure block 12 will not detach from the guide post 1101, thereby ensuring the stability of the pressure block 112 relative to the spring 111. This, in turn, ensures that the opening, closing and locking actions of the die-casting mold are smoother, and enhances the stability and reliability of production.

[0036] In summary, the die-casting mold of this invention effectively solves the problem of existing die-casting machines where the mold cannot be opened, thus reducing production cycle time and improving production efficiency. It also solves the product quality defects caused by the inability to open the mold, preventing product tearing and scrapping. Furthermore, it enables automated production without requiring a dedicated mold-adjusting mechanism or action, resulting in a simple structure and low manufacturing cost. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
