[0001] This utility model belongs to the field of cold stamping and casting mold technology, and specifically relates to a self-made wedge that saves more space. Background Technology

[0002] In modern manufacturing, cold stamping has become a core technology for steel sheet forming and processing due to its advantages of high efficiency, high precision and low cost. It is widely used in automobile manufacturing, home appliance production and other fields. As a key component of cold stamping dies, the wedge plays an important role.

[0003] The current announcement of Chinese utility model patent CN109834183A discloses a wedge mechanism, which is provided with a wedge slider and a wedge guide block on a moving mold base and a fixed mold base, and a forming insert is fixed on the wedge slider. It also includes a sliding component that is slidably disposed on the fixed mold base and can slide relative to the fixed mold base due to bearing external force. The wedge guide block is fixed on the sliding component and can switch between working position and non-working position due to following the sliding component. Through the above configuration, the wedge mechanism can actively select whether to make the forming insert have a forming stroke, so that the stamping die using the wedge mechanism can produce parts in two different states, thereby reducing the mold development cost.

[0004] The patented trolley guide plate consists of a side guide plate and a cover plate, which increases the required installation space. For molds with limited width, too many processes, and close proximity, this wedge structure cannot complete the structural design. Utility Model Content

[0005] The purpose of this invention is to provide a more space-saving self-made wedge, which solves the problem that the existing wedge mechanism, in which the trolley guide plate is composed of a side guide plate and a cover plate, increases the required installation space. For molds with limited width dimensions, when there are too many processes and the distances are close, this wedge structure cannot complete the structural design.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a more space-saving self-made wedge, including an upper mold, a lower mold and a wedge mechanism, wherein the wedge mechanism is disposed between the upper mold and the lower mold;

[0007] The wedge mechanism includes an upper mold fixing seat, a side guide plate, a slider, a slide groove, a base, a dovetail block, a fixing block, and a dovetail groove. The upper mold fixing seat is fixedly mounted on the upper mold, the side guide plate is fixedly mounted on the upper mold, the slider is located below the upper mold fixing seat, the slide groove is opened at the upper end of the slider, and the upper mold fixing seat contacts the slider. The base is fixedly mounted on the lower mold, the dovetail block is fixedly mounted on the base, the fixing block is fixedly mounted at the lower end of the slider, the dovetail groove is opened on the fixing block, and the dovetail block is located in the dovetail groove. The side guide plate has an L-shaped cross-section, and the extended portion of the side guide plate is located in the slide groove.

[0008] By adopting the above technical solution, an upper mold, a lower mold, and a wedge mechanism are set up. During use, the wedge mechanism is fixed between the upper mold and the lower mold. The wedge mechanism includes an upper mold fixing seat, a side guide plate, a slider, a slide groove, a base, a dovetail block, a fixing block, and a dovetail groove. The upper mold fixing seat is connected to the upper mold, and the movement and force of the press are transmitted by steel components. After the side guide plate and the cover plate are changed to be integrated, it not only guides the slider and restricts the slider's movement direction to ensure that the slider slides along the length of the side guide plate, but also reduces the overall width of the wedge through its own structural constraint, saving installation space. The slider slides along the side guide plate under the force of the upper mold fixing seat, realizing the lateral stamping action. The dovetail block and the dovetail groove cooperate to provide auxiliary guidance and positioning for the slider. The guiding accuracy of the V-shaped structure is used to improve the stability of the slider's movement and reduce the deviation and shaking during the slider's sliding process.

[0009] Furthermore: a return spring is fixedly installed at the upper end of the slider, and the other end of the return spring contacts the upper mold fixing seat. A return hook is provided between the base and the slider, with one end of the return hook installed on the slider and the other end installed on the base.

[0010] By adopting the above technical solution, a return spring and a return hook are set. The return spring drives the upper die fixing seat to move upward in the press, providing elastic restoring force and pulling the slide back to the initial position to prepare for the next stamping cycle. The return hook assists the return spring and works together to ensure that the slide returns stably and reliably, enhancing the synchronization and accuracy of the slide return.

[0011] Furthermore: the upper mold fixing seat is provided with a first bolt hole, the first bolt hole is equidistantly distributed along the width direction of the upper mold fixing seat, and the upper mold fixing seat and the upper mold are fastened by internal hexagon screws.

[0012] By adopting the above technical solution, and by setting the first bolt hole, the upper mold fixing seat is installed in the upper mold by passing multiple sets of internal hexagon screws through the first bolt hole during use, thereby improving the stability of the upper mold fixing seat during installation.

[0013] Furthermore: a transmission rod is fixedly provided on the slider, and the number of transmission rods is several and evenly distributed.

[0014] By adopting the above technical solution, a transmission rod is set up so that when the upper mold fixing seat is pressed down, the upper mold fixing seat contacts the transmission rod, and the downward pressure is transmitted to the slider through the transmission rod, thus avoiding damage to the slider caused by the downward pressure of the upper mold fixing seat.

[0015] Furthermore, a shim is fixedly provided on the upper surface of the slider, and the shim is in contact with the upper mold fixing seat.

[0016] By adopting the above technical solution and setting a shim, the shim can act as a buffer between the upper mold fixing seat and the slider during use, further protecting the slider.

[0017] Furthermore: the connection end between the return hook and the slider is provided with a hook groove, and the extension of the return hook near the slider end enters the hook groove.

[0018] Using the above technical solution, by setting a hook groove, one end of the return hook can be installed. When the upper mold is pressed down, the slider moves forward, the return hook is stretched and deformed, and the extension of the return hook slides in the hook groove. The return hook stores energy. When the upper mold returns, the hook elastically recovers and pulls the slider to move in the opposite direction through the hook groove, thus completing the reset.

[0019] Furthermore: the connection between the slide groove and the side guide plate is smoothly arranged, and the connection between the dovetail block and the dovetail groove is smoothly arranged.

[0020] By adopting the above technical solution, and by setting the connection between the slide groove and the side guide plate, and the dovetail block and the dovetail groove to be smooth, the slider can be made to slide more easily.

[0021] Furthermore, the base is provided with a second bolt hole, and the number of the second bolt holes is several and symmetrically arranged.

[0022] By adopting the above technical solution, by setting a second bolt hole, the base can be easily fixed in the lower mold by passing the fixing bolt through the second bolt hole.

[0023] In summary, this utility model has the following beneficial effects:

[0024] By setting up a wedge mechanism, the upper die fixing seat is connected to the upper die, and steel parts are used to transmit the motion and force of the press. After the side guide plate and cover plate are changed to be integrated, they not only guide the slider and restrict the slider's movement direction to ensure that the slider slides along the length of the side guide plate, but also reduce the overall width of the wedge through its own structural constraint, saving installation space. The slider is subjected to the force of the upper die fixing seat and slides along the side guide plate to realize the lateral stamping action. The dovetail block and dovetail groove cooperate to play an auxiliary guiding and positioning role for the slider. The guiding accuracy of the V-shaped structure is used to improve the stability of the slider's movement and reduce the deviation and shaking during the slider's sliding process.

[0025] By setting a return spring and a return hook, the return spring drives the upper die holder to move upward in the press, providing elastic restoring force and pulling the slide back to the initial position to prepare for the next stamping cycle. The return hook assists the return spring, working together to ensure that the slide returns stably and reliably, enhancing the synchronization and accuracy of the slide's return stroke.

[0026] Based on the above improvements, the overall technical effect achieved by this device is that it can integrate the side guide plate and the cover plate into one unit, and reduce the overall width of the wedge through its own structural constraints, thus saving installation space.
