Description

Technical Field

[0001] This utility model relates to the field of automotive punching die technology, and in particular to an automotive body punching die. Background Technology

[0002] A punching die for an automotive body is a die used to punch holes in automotive body parts (such as doors, roofs, and bodies). Through the punching die, holes can be processed quickly and accurately on the automotive body to meet the needs of automotive design.

[0003] For example, CN215032767U discloses a punching die for a car body for multi-hole processing, including: a housing, a base plate disposed on the housing, a longitudinal moving device disposed on the base plate, a horizontal moving device disposed on the longitudinal moving device and cooperating with the longitudinal moving device, a mounting plate disposed on the horizontal moving device, a flipping device disposed on the mounting plate, a workpiece to be processed disposed on the flipping device by a locking component, and a processing device disposed on the housing for punching the workpiece to be processed.

[0004] However, in the existing technology, the punching device applies a large pressure to the outer shell during the punching process. Excessive pressure will press the outer shell deeply into the mold. When multiple punching is required, the outer shell will be pressed multiple times, which will result in the outer shell getting stuck in the mold, making demolding difficult. At this time, forced demolding will cause a lot of friction between the outer shell and the mold, resulting in varying degrees of wear on the surface of the outer shell. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art that when multiple punching is required, the outer shell will be pressed multiple times, which will cause the outer shell to get stuck in the mold. Therefore, a punching mold for automobile outer shell is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a punching mold for an automobile body, comprising a punching device body, wherein a mold assembly is fixedly installed on the top of the punching device body;

[0007] The mold assembly includes a fixed mold, a movable mold, a fixed base, and a support rod. The movable mold is movably connected to the inside of the fixed mold. Connecting blocks are fixedly installed on both sides of the movable mold. One end of the support rod is rotatably connected to the inside of the connecting block. One end of the support rod is rotatably connected to a single-headed rotating rod. One end of the single-headed rotating rod is rotatably connected to one end of the fixed base.

[0008] Preferably, a support rod is fixedly connected between the fixed mold and the fixed base.

[0009] Preferably, a connecting rod is fixedly installed at the bottom of the movable mold.

[0010] Preferably, the connecting rod is inserted into the inside of the support rod.

[0011] Preferably, an opening is provided at the junction of the fixed mold and the connecting block.

[0012] Preferably, a receiving platform is fixedly installed on the upper surface of the fixed base.

[0013] Preferably, both the fixed mold and the movable mold have through holes at their bottoms.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, a complete mold is formed by a fixed mold and a movable mold. The movable mold is located at the bottom of the fixed mold. During the punching process, most of the outer shell is in contact with the fixed mold. During punching, the pressure generated by punching will press the outer shell onto the fixed mold. During the punching process, the single-head rotating rod can be rotated to drive the support rod, and the support rod can be used to lift the movable mold, thereby completing a simple demolding. This can effectively alleviate the problem of the outer shell getting stuck in the mold and can also assist in demolding, reducing the difficulty of subsequent demolding.

[0016] 2. In this utility model, by adding a connecting rod to the lower surface of the movable mold, the connecting rod is inserted inside the support rod, thus maintaining the stability of the movable mold in its normal state. When the support rod pushes the movable mold, the connecting rod can determine the direction of movement of the movable mold, so as to avoid the problem of misalignment between the movable mold and the fixed mold.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a punching die for an automobile body, including a punching device body 1. A die assembly 2 is fixedly installed on the top of the punching device body 1. The die assembly 2 includes a fixed die 21, a movable die 22, a fixed base 23, and a support rod 25. The movable die 22 is movably connected to the inside of the fixed die 21. Connecting blocks 29 are fixedly installed on both sides of the movable die 22. One end of the support rod 25 is rotatably connected to the inside of the connecting block 29. One end of the support rod 25 is rotatably connected to a single-headed rotating rod 24. One end of the single-headed rotating rod 24 is rotatably connected to one end of the fixed base 23. A support rod 26 is fixedly connected between the fixed die 21 and the fixed base 23.

[0027] The specific settings and functions of this embodiment are described below. The mold assembly 2 mainly consists of a fixed mold 21, a movable mold 22 and a fixed base 23. The fixed base 23 is installed on the punching device body 1 to determine the position of the entire mold assembly 2. The fixed mold 21 and the fixed base 23 are connected by a support rod 26, which ensures the overall structural strength and also leaves enough space to receive the waste generated during punching.

[0028] If the outer shell gets stuck between the outer shell and the mold, or if there is a risk of jamming, the single-head rotating rod 24 can be rotated. One end of the support rod 25 is rotatably connected to the single-head rotating rod 24, and the other end is rotatably connected to the connecting block 29 on the side of the movable mold 22. When the single-head rotating rod 24 rotates, it will push the movable mold 22 upward through the support rod 25. The movement of the movable mold 22 is used to complete the quick demolding, which can effectively alleviate the problem of the outer shell getting stuck in the mold, and can also assist in demolding and reduce the difficulty of subsequent demolding.

[0029] Example 2

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, a connecting rod 28 is fixedly installed at the bottom of the movable mold 22. The connecting rod 28 is inserted into the inside of the support rod 26. An opening 210 is provided at the junction of the fixed mold 21 and the connecting block 29. A receiving platform 27 is fixedly installed on the upper surface of the fixed base 23. A through hole 211 is provided at the bottom of both the fixed mold 21 and the movable mold 22.

[0031] The overall effect of this embodiment is that the docking rod 28 at the bottom of the movable mold 22 is inserted into the support rod 26, which can ensure that the movable mold 22 and the fixed mold 21 are stably docked together without affecting the normal punching of the outer shell. The existence of the opening 210 provides sufficient space for the rotation of the support rod 25.

[0032] During the process of the support rod 25 pushing the movable mold 22 to move, the connecting rod 28 will be pulled out from the support rod 26 to determine the moving path of the movable mold 22, so as to avoid misalignment between the movable mold 22 and the fixed mold 21. The presence of the through hole 211 facilitates the punching process, and the punched waste material falls into the receiving table 27.

[0033] The usage method and working principle of this device: When punching the car body, first place the car body on the fixed mold 21, then start the punching device body 1 to punch the car body. The waste generated by punching falls into the receiving table 27 through the through hole 211.

[0034] If there is a problem of jamming between the outer shell and the mold or if there is a potential for jamming, the single-head rotating rod 24 can be rotated. The single-head rotating rod 24 rotates around the connection point with the fixed base 23 and drives the support rod 25 in a synchronous manner. Since one end of the support rod 25 is rotatably connected to the single-head rotating rod 24 and the other end is rotatably connected to the connecting block 29 on the side of the movable mold 22, the support rod 25 will push the movable mold 22 when the single-head rotating rod 24 rotates.

[0035] Since the connecting rod 28 at the bottom of the movable mold 22 is inserted into the support rod 26, the movable mold 22 can only move upward. The movement of the movable mold 22 is used to complete the quick demolding, which can effectively alleviate the problem of the outer shell being stuck in the mold. It can also assist in demolding and reduce the difficulty of subsequent demolding. After handling, the single-head rotating rod 24 can be released.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present 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 for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
