Description

Technical Field

[0001] This utility model relates to the field of ball end plate processing technology, and more specifically to a precision pressing mold for forged ball end plates. Background Technology

[0002] Steering tie rod ball joints belong to a type of ball joint plate and are used in automotive parts. The working principle of a steering tie rod ball joint is that the tie rod with a ball joint housing has the ball joint of the steering spindle placed inside the ball joint housing. The ball joint is hinged to the edge of the shaft hole of the ball joint housing through the ball joint seat at its front end. The needle roller between the ball joint seat and the steering spindle is embedded in the groove of the inner hole surface of the ball joint seat. This utility model has the characteristics of reducing ball joint wear and improving the tensile strength of the spindle. Usually, when manufacturing tie rod ball joints, a precision die is required to form the heated object.

[0003] However, existing precision pressing dies for forging ball heads extract the object directly from the forming die head using external equipment after forming, causing the object to fall directly. During this process, the object has a short cooling time in the die head and lacks a mechanism to continuously maintain the cooling effect of the object. As a result, when several formed objects are placed, they pile up together, and the objects still retain high temperatures, posing a safety hazard. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a precision pressing mold for forging ball head plates, which solves the problem that the prior art lacks a mechanism to continuously maintain the cooling effect of the object, resulting in several formed objects piling up together when placed, and the objects still having high temperature, which poses a safety hazard.

[0005] This utility model provides the following technical solution: a precision pressing mold for forging ball head plates, including a mold body, a pre-treatment mold head installed on one side of the mold body, a forming mold head installed on the outside of the pre-treatment mold head on one side of the mold body, and a heat dissipation track mechanism and an intermittent blocking mechanism. The heat dissipation track mechanism is disposed on one side of the forming mold head, a placement component is disposed inside the forming mold head, and one side of the heat dissipation track mechanism is located inside the placement component. The heat dissipation track mechanism extends to the lower right of the forming mold head, and a cold liquid inlet / outlet restriction component is disposed at the right end of the heat dissipation track mechanism. The cold liquid inlet / outlet restriction component communicates with the interior of the heat dissipation track. The intermittent blocking mechanism is disposed on the inner wall of the cold liquid inlet / outlet restriction component, and one end of the intermittent blocking mechanism slidably penetrates the top of the cold liquid inlet / outlet restriction component. An actuating component is installed on one side of the mold body near the forming mold head, and one end of the actuating component is fixedly connected to the top of the intermittent blocking mechanism.

[0006] Furthermore, the placement component includes a heat-conducting cavity, which is disposed inside the molding die head and close to the outer side of the molding die head inlet.

[0007] Furthermore, the heat dissipation track mechanism includes a spiral tube, a first heat dissipation guide rail, a second heat dissipation guide rail, and a flow channel. The spiral tube is disposed inside the placement component. The inlet of the spiral tube is fixedly connected to the first heat dissipation guide rail, and the outlet of the spiral tube is fixedly connected to the second heat dissipation guide rail. The first and second heat dissipation guide rails are symmetrically arranged. Both the first and second heat dissipation guide rails are provided with flow channels inside. The inlet and outlet of the spiral tube are respectively connected to the two flow channels.

[0008] Furthermore, the coolant inlet / outlet device includes a limiting ring, a guide hole, a connecting cavity, an inlet pipe, and an outlet pipe. One end of the limiting ring is fixedly connected to one end of the first and second heat dissipation guide rails. Guide holes are provided at the bottom of the limiting ring, the bottom of the first and second heat dissipation guide rails, and connecting cavities are provided on both sides inside the limiting ring. An inlet pipe is fixedly connected to the bottom of the limiting ring near the first heat dissipation guide rail, and an outlet pipe is fixedly connected to the bottom of the limiting ring near the second heat dissipation guide rail. A receiving groove is provided at the top of the inner wall of the limiting ring.

[0009] Furthermore, the starting component includes a cylinder and a connecting rod. The cylinder is installed on one side of the mold body, and the connecting rod is fixedly connected to the output end of the cylinder.

[0010] Furthermore, the intermittent blocking mechanism includes a movable rod and a stop block. The outer wall of the movable rod is slidably connected to the inside of the cold liquid inlet / outlet placement component, and the outer wall of the movable rod penetrates the top of the cold liquid inlet / outlet placement component. A stop block is fixedly connected to one end of the movable rod.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. In the initial state of this utility model, the stop block is separated from the receiving groove and located inside the limiting ring. Through the cooperation of the liquid inlet pipe, a flow channel, a spiral tube, another flow channel, and the liquid outlet pipe, a coolant circulation channel can be formed. Due to the effect of the spiral tube, the mold is accelerated to cool the mold when the object is being formed in the mold. When the formed object is pulled out of the mold head by the external device, the ball head at the top of the object is located inside the first and second heat dissipation guide rails and continues to slide. The two flow channels continuously cool the sliding ball head. Then the ball head is located inside the limiting ring and contacts one side of the stop block, thereby maintaining the cooling effect at the ball head. After the next object is formed, the stop block is moved into the receiving groove by the cylinder, so that the currently cooled object falls out of the limiting ring, thereby fully cooling the ball head.

[0018] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0019] Appendix Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0020] See attached document Figures 1-4A precision pressing die for forging ball-end plates includes a die body 1, a pretreatment die head 2 mounted on one side of the die body 1, and a forming die head 3 mounted on the outer side of the die body 1 near the pretreatment die head 2. It also includes a heat dissipation track mechanism and an intermittent blocking mechanism. The heat dissipation track mechanism is located on one side of the forming die head 3, and a placement component is provided inside the forming die head 3. One side of the heat dissipation track mechanism is located inside the placement component and extends to the lower right of the forming die head 3. A cold liquid inlet / outlet restriction component is provided at the right end of the heat dissipation track mechanism, communicating with the interior of the heat dissipation track. The intermittent blocking mechanism is located on the inner wall of the cold liquid inlet / outlet restriction component, and one end of the intermittent blocking mechanism slidably penetrates the top of the cold liquid inlet / outlet restriction component. An actuating component is mounted on one side of the die body 1 near the forming die head 3, and one end of the actuating component is fixedly connected to the top of the intermittent blocking mechanism. In the initial state, the actuating component drives the intermittent blocking mechanism to move downwards, causing the intermittent blocking mechanism to be positioned in the cold liquid... Inside the inlet / outlet restrictor, a coolant circulation channel can be formed through the heat dissipation track mechanism and the coolant inlet / outlet restrictor. Therefore, after the object is shaped inside the forming mold head 3, one end of the heat dissipation track mechanism is located inside the placement part, which facilitates the cooling of the shaped object. Subsequently, when the object is pulled out of the forming mold head 3 by external equipment and the restriction on the object is released, the ball head of the object is located in the heat dissipation track mechanism. When the ball head slides in the heat dissipation guide mechanism, it is cooled by the flowing coolant. When the ball head moves into the coolant inlet / outlet restrictor, the ball head is restricted by the intermittent blocking mechanism to maintain the cooling effect at the ball head. After the next object is shaped, the starting part drives the intermittent blocking mechanism to move upward to be flush with the inner wall of the coolant inlet / outlet restrictor, releasing the restriction on the current ball head and causing the ball head to fall out of the coolant inlet / outlet restrictor. Then, the starting part resets the intermittent blocking mechanism to facilitate blocking the next ball head.

[0021] Specifically, the placement component includes a heat-conducting cavity 4, which is located inside the forming mold head 3 and close to the outside of the inlet of the forming mold head 3; when one end of the heat dissipation track mechanism is located inside the heat-conducting cavity 4, it can cool the formed object.

[0022] Specifically, the heat dissipation track mechanism includes a spiral tube 5, a first heat dissipation guide rail 6, a second heat dissipation guide rail 7, and a flow channel 10. The spiral tube 5 is located inside the placement component. The inlet of the spiral tube 5 is fixedly connected to the first heat dissipation guide rail 6, and the outlet of the spiral tube 5 is fixedly connected to the second heat dissipation guide rail 7. The first heat dissipation guide rail 6 and the second heat dissipation guide rail 7 are symmetrically arranged. Both the first heat dissipation guide rail 6 and the second heat dissipation guide rail 7 are provided with flow channels 10 inside. The inlet and outlet of the spiral tube 5 are respectively connected to the two flow channels 10. One end of the object first enters the pre-treatment mold head 2 for preliminary shaping. Then, the object is extracted from the pre-treatment mold head 2 by an external mobile device and introduced into the forming mold head 3 for complete shaping. At this time, when the coolant passes through the spiral tube 5, it facilitates the accelerated cooling of the forming mold.

[0023] Specifically, the coolant inlet / outlet device includes a limiting ring 8, a guide hole 9, a connecting cavity 11, an inlet pipe 12, and an outlet pipe 13. One end of the limiting ring 8 is fixedly connected to one end of the first heat dissipation rail 6 and the second heat dissipation rail 7. Guide holes 9 are provided at the bottom of the limiting ring 8, the bottom of the first heat dissipation rail 6, and the bottom of the second heat dissipation rail 7. Connecting cavities 11 are provided on both sides inside the limiting ring 8. Through the cooperation of the inlet pipe 12, one flow channel 10, the spiral tube 5, another flow channel 10, and the outlet pipe 13, a coolant circulation channel can be formed. A liquid inlet pipe 12 is fixedly connected to the bottom of the limiting ring 8 near the first heat dissipation guide rail 6, and a liquid outlet pipe 13 is fixedly connected to the bottom of the limiting ring 8 near the second heat dissipation guide rail 7. A storage groove 17 is opened on the top of the inner wall of the limiting ring 8. When the molded object is pulled out from the molding mold head 3 by the external setting and comes into contact with the limiting of the object, the ball head at the top of the object is located inside the first heat dissipation guide rail 6 and the second heat dissipation guide rail 7 and continues to slide, while the bottom of the object passes through the guide hole 9 and cooperates with the two flow channels 10 to continuously cool the sliding ball head.

[0024] Specifically, the starting components include a cylinder 14 and a connecting rod 15. The cylinder 14 is installed on one side of the mold body 1, and the connecting rod 15 is fixedly connected to the output end of the cylinder 14. Starting the cylinder 14 causes the output end of the cylinder 14 to drive the connecting rod 15 to move up and down, thereby facilitating the connecting rod 15 to drive the intermittent blocking mechanism to move up and down.

[0025] Specifically, the intermittent blocking mechanism includes a movable rod 16 and a stop 18. The outer wall of the movable rod 16 is slidably connected to the inside of the cold liquid inlet / outlet placement component, and the outer wall of the movable rod 16 penetrates the top of the cold liquid inlet / outlet placement component. One end of the movable rod 16 is fixedly connected to the stop 18, and the top of the movable rod 16 is fixedly connected to the bottom of the connecting rod 15. In the initial state, the stop 18 is located below the storage groove 17, which facilitates the restriction of the ball head of the object inside the limiting ring 8.

[0026] The working principle and usage process of this utility model are as follows: In the initial state, the stop 18 is separated from the receiving groove 17 and located inside the limiting ring 8. Through the cooperation of the liquid inlet pipe 12, one flow channel 10, the spiral tube 5, another flow channel 10, and the liquid outlet pipe 13, a coolant circulation channel can be formed. One end of the object first enters the pre-treatment mold head 2 for preliminary shaping. Then, the object is pulled out from the pre-treatment mold head 2 by an external mobile device and introduced into the forming mold head 3 for complete shaping. At this time, when the coolant passes through the spiral tube 5, it facilitates accelerated cooling of the forming mold. When the formed object is pulled out of the forming mold head 3 by the external device and the restriction on the object is released, the ball head at the top of the object is located on the first heat dissipation guide rail 6. The ball head slides continuously inside the second heat dissipation guide rail 7, while the bottom of the object passes through the guide hole 9. The ball head is continuously cooled by the two flow channels 10. Finally, the ball head slides into the limiting ring 8 and the outer wall contacts the side of the stop block 18. The flowing coolant maintains the cooling effect at the ball head. After the next object is formed, the cylinder 14 is activated, which drives the connecting rod 15 to move upward. The connecting rod 15 drives the moving rod 16 to move upward. The moving rod 16 then moves the stop block 18 into the receiving groove 17, so that the cooled object falls out of the limiting ring 8. After the object falls out, the stop block 18 is reset to block the next ball head, thus fully cooling the ball head.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
