Description

A hot forging die that facilitates demolding Technical Field

[0001] This utility model relates to the field of molding die technology, specifically a hot forging molding die that is easy to demold. Background Technology

[0002] Hot forging dies are tools used to process metal parts in high-temperature environments. They are made by heating and softening metal materials and placing them into the mold cavity, then pressing them into a specific shape with the help of external force. These dies are usually made of special materials that are resistant to high temperatures and have high strength. They can withstand repeated impacts and drastic temperature changes and are often used in the production of metal parts with complex structures and high strength requirements, such as automotive engine parts and tool accessories in the mechanical manufacturing field.

[0003] Existing small hot forging forming dies mostly use built-in demolding bars to assist in demolding. The demolding bar fuses with the material through the demolding plate and pulls the workpiece out directly after cooling. Although this method has the advantages of simple structure and convenient operation, in actual applications, the positioning accuracy of the demolding bar directly affects the demolding effect. Slight deviations can easily cause local deformation or residual stress due to uneven force. In addition, the concentrated stress generated by mechanical demolding can easily lead to workpiece breakage, which seriously affects the yield of finished products. In view of this, we provide a hot forging forming die that facilitates demolding. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a hot forging mold that is easy to demold.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot forging forming mold that facilitates demolding, comprising a hot forging mold, wherein the top surface of the hot forging mold has multiple forming grooves, and a lifting plate is slidably connected to the center of the inner cavity of the hot forging mold, and the top surface of the lifting plate is provided with multiple lifting components; multiple vertical guide rails are fixedly connected to both sides of the inner wall of the hot forging mold; a drive motor is fixedly connected to one side of the inner cavity of the hot forging mold, and a bidirectional screw is fixedly connected to the outer wall of the output end of the drive motor; the bidirectional screw is rotatably connected to the lower end of the inner cavity of the hot forging mold; multiple horizontal guide grooves are provided on both sides of the inner wall of the hot forging mold, and a set of corresponding symmetrical components are slidably connected to both ends of the horizontal guide grooves; and multiple tension springs are sleeved on both sides of the inner cavity of the hot forging mold.

[0006] As described above, the top of the outer wall of the lifting component is located at the lower end of the forming groove, and the top surface contour of the lifting component matches the inner wall of the forming groove. The top of the outer wall of the lifting component is slidably connected to the inner wall of the forming groove.

[0007] As described above, the outer wall of the vertical guide rail penetrates one side of the inside of the lifting plate, and the inside of the lifting plate is slidably connected to the outer wall of the vertical guide rail.

[0008] As described above, one end of the outer wall of the bidirectional screw passes through the inner center of the symmetrical component, and the bidirectional screw is connected to the inner center thread of the symmetrical component through the outer wall thread.

[0009] As described above, the top surface of the symmetrical component has an inclined surface on one side, and the multiple symmetrical components are arranged symmetrically.

[0010] As mentioned above, multiple rounded corners are provided on both sides of the bottom surface of the lifting plate, and the rounded corners of the bottom surface of the lifting plate are in close contact with the inclined surface provided on one side of the top surface of the symmetrical component.

[0011] As described above, the outer wall of the bottom end of the tension spring is fixedly connected to the lower end of the inner wall of the hot forging die, and the outer wall of the top end of the tension spring is fixedly connected to one side of the bottom surface of the lifting plate.

[0012] Compared with existing technologies, this easy-to-demold hot forging die has the following advantages:

[0013] 1. After the material is cooled, the bidirectional screw driven by the drive motor can move the two symmetrical components on both sides synchronously towards the center. The inclined surface of the symmetrical component contacts the rounded corner structure at the bottom of the lifting plate, converting the horizontal thrust into a vertical lifting force, which pushes the lifting component to rise steadily. During the lifting process, the lifting component evenly lifts the workpiece, eliminating the phenomenon of local stress concentration and avoiding deformation or breakage of the workpiece due to uneven force.

[0014] Second, after the demolding operation of the workpiece is completed, the elastic characteristics of the tension spring can be used to pull the lifting plate down to reset it, providing a reliable base positioning for the next demolding operation.

[0023] 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.

[0024] As shown in Figures 1-6, this utility model provides a technical solution: a hot forging forming mold that is easy to demold, including a hot forging mold 1. The top surface of the hot forging mold 1 has multiple forming grooves 101, and a lifting plate 2 is slidably connected to the center of the inner cavity of the hot forging mold 1. The top surface of the lifting plate 2 is provided with multiple lifting components 201. Multiple vertical guide rails 202 are fixedly connected to both sides of the inner wall of the hot forging mold 1. A drive motor 3 is fixedly connected to one side of the inner cavity of the hot forging mold 1, and a bidirectional screw 301 is fixedly connected to the outer wall of the output end of the drive motor 3. The bidirectional screw 301 is rotatably connected to the lower end of the inner cavity of the hot forging mold 1. Multiple horizontal guide grooves 302 are opened on both sides of the inner wall of the hot forging mold 1, and a set of corresponding symmetrical components 303 are slidably connected to both ends of the horizontal guide grooves 302. Multiple tension springs 304 are sleeved on both sides of the inner cavity of the hot forging mold 1.

[0025] The drive motor 3 drives the bidirectional screw 301 to move the two symmetrical components 303 synchronously toward the center. The inclined surface 305 of the symmetrical component 303 contacts the rounded corner structure at the bottom of the lifting plate 2, converting the horizontal thrust into a vertical lifting force, which pushes the lifting component 201 to rise steadily. During the lifting process, the lifting component 201 evenly lifts the workpiece.

[0026] As shown in Figure 4, the top of the outer wall of the lifting component 201 is located at the lower end of the inside of the forming groove 101, and the top surface contour of the lifting component 201 fits into the inner wall of the forming groove 101. The top of the outer wall of the lifting component 201 is slidably connected to the inner wall of the forming groove 101.

[0027] The top of the outer wall of the lifting component 201 extends to the bottom of the forming groove 101. Its top surface contour is precisely fitted with the shape of the inner wall of the groove. Vertical displacement is achieved through the sliding fit between the top of its outer wall and the inner wall of the forming groove 101, ensuring complete coverage of the contact surface with the workpiece during the lifting process.

[0028] As shown in Figure 6, the outer wall of the vertical guide rail 202 penetrates one side of the inside of the lifting plate 2, and the inside of the lifting plate 2 is slidably connected to the outer wall of the vertical guide rail 202.

[0029] The vertical guide rail 202 can use its outer wall to restrict the lifting trajectory of the lifting plate 2, ensuring that it does not deviate from the expected trajectory.

[0030] As shown in Figure 6, one end of the outer wall of the bidirectional screw 301 passes through the inner center of the symmetrical component 303, and the bidirectional screw 301 is connected to the inner center thread of the symmetrical component 303 through the outer wall thread.

[0031] The bidirectional screw 301, through its bidirectional symmetrical thread on its outer wall, can synchronously drive two sets of symmetrical components 303 to move in opposite directions along the horizontal guide groove 302 when it rotates, ensuring that the lifting plate 2 is subjected to balanced force.

[0032] As shown in Figures 4-6, a sloping surface 305 is provided on one side of the top surface of the symmetrical component 303, and multiple symmetrical components 303 are arranged symmetrically.

[0033] By arranging the symmetrical components 303 in a mirror-symmetrical manner, the inclined surface 305 and the rounded corner structure at the bottom of the lifting plate 2 form a sliding fit, ensuring that the forces on both sides are balanced when the bidirectional screw 301 is driven, avoiding unilateral offset, and ensuring synchronous and stable lifting action.

[0034] As shown in Figures 4 and 5, multiple rounded corners are provided on both sides of the bottom surface of the lifting plate 2, and the rounded corners of the bottom surface of the lifting plate 2 are in close contact with the inclined surface 305 provided on one side of the top surface of the symmetrical component 303.

[0035] When the symmetrical component 303 moves horizontally, the inclined surface 305 and the rounded corner form a continuous sliding contact, smoothly converting the horizontal thrust into a vertical lifting force, ensuring that the lifting action is continuous and the force transmission is stable.

[0036] As shown in Figure 4, the outer wall of the bottom end of the tension spring 304 is fixedly connected to the lower end of the inner wall of the hot forging die 1, and the outer wall of the top end of the tension spring 304 is fixedly connected to one side of the bottom surface of the lifting plate 2.

[0037] The tension spring 304 provides a reset effect for the lifting plate 2 through its own elastic characteristics.

[0038] Working principle: The top of the outer wall of the lifting component 201 extends to the bottom of the forming groove 101. Its top surface contour precisely matches the shape of the inner wall of the groove. Vertical displacement is achieved through the sliding fit between the top of its outer wall and the inner wall of the forming groove 101, ensuring complete coverage of the contact surface with the workpiece during the lifting process. The vertical guide rail 202 can use its own outer wall to limit the lifting trajectory of the lifting plate 2, ensuring that it will not deviate from the expected trajectory. The bidirectional screw 301, through the bidirectional symmetrical threads provided on its outer wall, can synchronously drive the two sets of symmetrical components 303 along the horizontal guide groove 3 when the bidirectional screw 301 rotates. 02. Reverse movement ensures balanced force on the lifting plate 2. By arranging the symmetrical components 303 in a mirror-symmetrical manner, the inclined surface 305 and the rounded corner structure at the bottom of the lifting plate 2 form a sliding fit, ensuring that the forces on both sides are balanced when the bidirectional screw 301 is driven, avoiding unilateral offset, and ensuring synchronous and stable lifting action. When the symmetrical components 303 move horizontally, the inclined surface 305 and the rounded corner form a continuous sliding contact, smoothly converting the horizontal thrust into the vertical lifting force, ensuring that the lifting action is continuous and the force transmission is stable. The tension spring 304 provides a reset effect for the lifting plate 2 through its own elastic characteristics.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
