Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an automobile brake base plate mold that facilitates material discharge. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube and profile materials to cause plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size. The production of automobile brake base plates is completed using stamping dies.

[0003] A search revealed that the Chinese patent "A Stamping Die for Easy Material Unloading" (authorization announcement number CN221109532U) uses a pusher plate and a blanking plate. When the workpiece protrudes inside the pressure groove, the pusher plate, driven by a hydraulic cylinder, can push the workpiece to the blanking plate, allowing it to slide down according to the angle of inclination of the blanking plate. This achieves automatic material unloading and reduces the danger of manual material handling. However, in actual use, this method has the following drawbacks: although automatic unloading is achieved, the workpiece is prone to collisions with the lower die base and blanking plate during the unloading process, affecting the quality of the workpiece. Utility Model Content

[0004] Therefore, it is necessary to provide an automotive brake base plate mold that facilitates material discharge, addressing the problem of workpieces easily colliding with the lower mold base and the blanking plate.

[0005] A convenient automotive brake base plate mold includes a base and a lower mold mounted on its outer side, wherein the lower mold has an ejector mechanism inside; it also includes an ejector mechanism, which is located on the outer side of the lower mold and is used to reduce collisions while completing the ejection of the brake base plate; wherein the ejector mechanism includes two support bars and two guide bars, each of which has a limit groove, the support bars can move horizontally along the direction of the guide bars, and the guide bars are bent.

[0006] In one embodiment, a vertical plate is slidably connected to the base, one end of the support bar is installed to the outside of the vertical plate, and a horizontally movable abutment is provided on the outside of the vertical plate.

[0007] In one embodiment, one end of the guide bar is installed to the outside of the lower mold, and a limit frame is provided between the two guide bars, the inner top wall of the limit frame being provided with an arc surface.

[0008] In one embodiment, a set of equally spaced balls are embedded in the guide strip, and the balls are located in a limiting groove.

[0009] In one embodiment, a first electric push rod is provided between the lower mold and the vertical plate, and a second electric push rod that docks with the abutment seat is installed on the vertical plate.

[0010] In one embodiment, a third electric push rod is installed on the side of the lower mold away from the vertical plate, and a rubber strip is provided at the end of the third electric push rod.

[0011] In one embodiment, a transfer plate is mounted at the other end of one of the guide bars, and the transfer plate is bent.

[0012] In one embodiment, the ejector mechanism includes two fourth electric push rods, a receiving ring, and a set of ejector rods. The fourth electric push rods are installed inside the lower mold, the receiving ring is disposed between the fourth electric push rods and the ejector rods, and one end of the ejector rods extends into the interior of the lower mold.

[0013] Beneficial effects 1. By setting support bars and guide bars, the support bars are used to receive and transfer the brake base plate after stamping, and the guide bars are used to guide and transport the brake base plate on the support bars to complete the discharge of the brake base plate. During the discharge process, the phenomenon of workpiece collision under force is avoided, thus ensuring the quality of the workpiece. 2. By setting ball bearings, the workpiece can move using its own weight. Combined with the transfer plate, the workpiece is tilted and supported, so that the side of the workpiece after tilting comes into contact with the conveyor belt. Then, it is pulled by the conveyor belt to complete the conveying, which reduces excessive wear and collision during the workpiece discharge process and ensures the quality of the workpiece.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] The following is combined Figures 1-5 This invention describes an automotive brake base plate mold that facilitates material discharge.

[0019] In one embodiment, a car brake base plate mold for easy material discharge includes a base 100 and a lower mold 200 mounted on its outer side. The lower mold 200 has an ejector mechanism 300 inside. It also includes a discharge mechanism 400, which is located on the outer side of the lower mold 200 and is used to reduce the occurrence of collisions while completing the discharge operation of the brake base plate. The discharge mechanism 400 includes two support bars 410 and two guide bars 420. Limiting grooves are provided on both the support bars 410 and the guide bars 420. The support bars 410 can move horizontally along the direction of the guide bars 420, and the guide bars 420 are bent.

[0020] like Figure 1 and Figure 3 As shown, a vertical plate 110 is slidably connected to the base 100, one end of the support bar 410 is installed to the outside of the vertical plate 110, and a horizontally movable abutment seat 111 is provided on the outside of the vertical plate 110.

[0021] In this embodiment, after the stamping operation is completed, the workpiece is ejected by the ejector mechanism 300, and then the support bar 410 is driven to move to below the workpiece. Then the ejector mechanism 300 is reset, and the workpiece is on the support bar 410. Next, the vertical plate 110 moves to drive the support bar 410 to move closer to the guide bar 420. After the movement is in place, the abutment seat 111 is driven to move the workpiece from the support bar 410 to the guide bar 420, completing the workpiece discharge from the stamping area. Then, affected by the bending of the guide bar 420, the material slides under its own weight and falls onto the conveyor belt, completing the discharge operation. It should be noted that there is a gap between the support bar 410 and the lower mold 200, which facilitates the insertion of materials; The distance between the two support bars 410 and the two guide bars 420 can be adjusted according to the specifications of the brake base plate.

[0022] like Figure 1 and Figure 2 As shown, one end of the guide bar 420 is installed on the outside of the lower mold 200, and a limit frame 421 is provided between the two guide bars 420. The inner top wall of the limit frame 421 is provided with an arc surface.

[0023] The use of the limiting bracket 421 can cover and limit the top of the workpiece when it moves from the support bar 410 to the guide bar 420, ensuring the docking effect. Combined with the arc surface, it can guide the workpiece to resist contact.

[0024] like Figure 2 As shown, a set of equally spaced balls 422 are embedded on the guide bar 420, and the balls 422 are in the limiting groove.

[0025] The use of a limiting groove facilitates the support and transfer of the workpiece, reducing the possibility of accidental workpiece displacement. Combined with the 422 ball bearings, it helps to reduce wear during workpiece movement and ensure workpiece quality.

[0026] like Figure 1 and Figure 3 As shown, a first electric push rod 210 is provided between the lower mold 200 and the vertical plate 110, and a second electric push rod 112 that is connected to the abutment seat 111 is installed on the vertical plate 110.

[0027] After the workpiece is ejected from the lower mold 200, the first electric push rod 210 is activated, causing the vertical plate 110 to move the support bar 410 to support the workpiece. Then, the second electric push rod 112 is used to move the contact seat 111, so that the workpiece is abutted from the support bar 410 to the guide bar 420, completing the transfer.

[0028] like Figure 1As shown, a third electric push rod 220 is installed on the side of the lower mold 200 away from the vertical plate 110, and a rubber strip 221 is provided at the end of the third electric push rod 220.

[0029] During the unloading process, when the workpiece is about to move to the end of the guide bar 420, the third electric push rod 220 can be activated to move the rubber strip 221 to assist in pushing the workpiece and ensure the arrival rate.

[0030] like Figure 1 As shown, a transfer plate 423 is installed at the other end of one of the guide bars 420, and the transfer plate 423 is bent.

[0031] When it is necessary to transfer the workpiece to the conveyor belt, the transfer plate 423 can be used to tilt and receive the workpiece. After the workpiece is tilted, its side will contact the conveyor belt, and then it will be pulled by the conveyor belt to complete the discharge.

[0032] like Figure 1 and Figure 5 As shown, the ejector mechanism 300 includes two fourth electric push rods 310, a receiving ring 320 and a set of ejector rods 330. The fourth electric push rods 310 are installed inside the lower mold 200, the receiving ring 320 is disposed between the fourth electric push rods 310 and the ejector rods 330, and one end of the ejector rods 330 extends into the interior of the lower mold 200.

[0033] When the workpiece is demolded, the fourth electric push rod 310 is activated, which then causes the receiving ring 320 to drive the ejector rod 330 to move, pushing the workpiece upward and separating it from the lower mold 200.

[0034] Working principle: When the material moves to the lower die 200, the press is then started to drive the upper die to move and complete the stamping process of the workpiece. After stamping, the ejector rod 330 drives the workpiece to move upward. Then the support bar 410 moves horizontally to the bottom of the workpiece for support. Next, the support bar 410 moves horizontally again to the guide bar 420. Then the contact seat 111 abuts against the workpiece and moves to the guide bar 420. Then, affected by the inclination of the guide bar 420, it cooperates with the ball bearing 422 to make the workpiece slide on the guide bar 420. After sliding into place, the third electric push rod 220 drives the rubber strip 221 to move the workpiece to the transfer plate 423, so that the workpiece is in an inclined state and in contact with the conveyor belt. Then, during the movement of the conveyor belt, the workpiece is pulled down onto the conveyor belt, completing the overall unloading operation.

[0035] It should be noted that the first electric actuator 210, the second electric actuator 112, the third electric actuator 220, and the fourth electric actuator 310 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the first electric actuator 210, the second electric actuator 112, the third electric actuator 220, and the fourth electric actuator 310 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
