This utility model relates to the technical field of motorcycle lower pump piston processing molds, and particularly to a motorcycle lower pump piston processing mold that facilitates material ejection. It includes a worktable, a base, a lower mold, guide rods, a slide block, an upper mold, and a cylinder. The base is fixedly connected to the worktable, and four guide rods are also fixedly connected to the worktable. A cylinder is mounted on the worktable, and a slide block is mounted on the cylinder's telescopic rod. The slide block slides on the four guide rods, and the upper mold is mounted on the slide block. The lower mold is held within the base. The mold also includes a pusher frame, a cam, a mounting seat, and a motor. The mounting seat is installed within the worktable, and the motor is mounted on the mounting seat. A cam is mounted on the motor's output shaft, and two pusher frames are slidably arranged on the worktable. By starting the motor, the motor's output shaft drives the cam to rotate, pushing the guide seat.

This prevents the forming piston from being too tightly fitted to the lower mold, thus accelerating the material ejection process.

Description

Technical Field

[0001] This utility model relates to the field of motorcycle lower pump piston processing mold technology, and in particular to a motorcycle lower pump piston processing mold that facilitates material unloading. Background Technology

[0002] The lower cylinder piston of a motorcycle is the core actuator of a disc brake system and is an internal component of the brake caliper. It achieves braking by hydraulically pushing the brake pads to clamp the brake disc. The mold is a tool specifically used to manufacture the internal piston of the lower cylinder in a motorcycle brake system.

[0003] Patent CN208408273U discloses a mold for machining a motorcycle disc brake upper pump assembly. It includes a guide post, positioning hole, upper template, pressure plate, spring buffer pad, lower template, mold handle, and support plate. The outer wall of the bottom end of the guide post is connected to a circular hole on the surface of the support plate, and the two fit together. The positioning hole is located on the edge of the support plate surface, and the top center of the support plate is fixedly connected to the bottom end of the upper template. When using this patent, the lower template supports the equipment, and the pressure plate compresses the disc brake. However, this existing patent lacks an ejector mechanism. After compression, the workpiece is firmly attached to the mold cavity due to a vacuum effect, making it impossible to manually remove the molded part. Using tools can easily damage the workpiece.

[0004] Therefore, there is a need to provide a machining mold for the motorcycle lower pump piston that facilitates material removal. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patented ejector mechanism, which is that after compression, the workpiece will be firmly attached to the mold cavity due to the vacuum effect of the material, and the molded part cannot be manually removed from the mold, and the workpiece is easily damaged when using tools, this utility model provides a motorcycle lower pump piston processing mold that facilitates material ejection. Through components such as pusher frame, elastic element and guide seat, the molded part can be quickly ejected.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a motorcycle lower pump piston processing mold for easy material ejection, comprising a worktable, a base, a lower mold, guide rods, a slide block, an upper mold, and a cylinder. The base is fixedly connected to the worktable, and four guide rods are fixedly connected to the worktable. A cylinder is mounted on the worktable, and a slide block is mounted on the cylinder's telescopic rod. The slide block slides on the four guide rods, and an upper mold is mounted on the slide block. The lower mold is held within the base. The mold also includes a pusher frame, elastic elements, a guide seat, a cam, a mounting base, and a motor. A mounting base is mounted within the worktable, and a motor is mounted on the mounting base. A cam is mounted on the motor's output shaft. Two pusher frames are slidably arranged on the worktable, and two elastic elements are fitted onto the pusher frames. The two ends of the elastic elements are connected to the pusher frames and the worktable, respectively. A guide seat is fixedly connected between the two pusher frames.

[0007] As a further preferred option, it also includes electric guide rails, sliding frames, guide plates, limit seats, and mounting blocks. Four electric guide rails are installed on both the base and the slide. A sliding frame is installed between two electric guide rails on the same side. Four guide plates are fixedly connected to the base. Two mounting blocks are fixedly connected to both the lower mold and the upper mold. Limit seats are fixedly connected to the sliding frame.

[0008] As a further preferred option, it also includes image detectors and warning devices. Two image detectors are mounted on the base, and four warning devices are mounted on the base. The image detectors are electrically connected to two adjacent warning devices.

[0009] As a further preferred option, four feet are fixedly connected to the workbench.

[0010] As a further preferred option, a limit block is fixedly connected to the guide rod.

[0011] As a further preferred option, the base and the worktable are fixedly connected by two reinforcing ribs.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By starting the motor, the output shaft of the motor drives the cam to rotate and push the guide seat. The guide seat drives the two pusher frames to move upward synchronously, thereby pushing the forming piston out of the lower mold, thus avoiding the forming piston from fitting too tightly with the lower mold and speeding up the material output efficiency.

[0013] 2. By inserting the upper mold of the corresponding specification into the slide block and the lower mold into the base, the electric slider of the electric guide rail is driven to move inward. The electric slider drives the sliding frame and the limit seat to move inward, so that the limit seat is inserted into the mounting block on the corresponding upper or lower mold. This achieves the effect of quick assembly and disassembly of the upper and lower molds, allowing the corresponding upper and lower molds to be replaced as needed, thus improving the practicality of the equipment.

[0014] 3. Defect detection of finished parts is performed by an image detector, and the detection data is transmitted to the control module for analysis. When an abnormality is detected, the control module triggers the nearest alarm to remind the operator to intervene and ensure processing quality. Attached Figure Description

Detailed Implementation

[0021] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0022] Example 1: A machining mold for a motorcycle lower pump piston that facilitates material removal, see reference. Figures 1-5 As shown, the assembly includes a worktable 1, a base 2, a lower mold 3, guide rods 4, a slide block 5, an upper mold 6, and a cylinder 7. The base 2 is welded to the top of the worktable 1. Guide rods 4 are symmetrically welded to the left and right sides of the top of the worktable 1. The cylinder 7 is bolted to the top of the worktable 1. The slide block 5 is mounted on the telescopic rod of the cylinder 7 and slides on the four guide rods 4. The upper mold 6 is located at the bottom of the slide block 5. The lower mold 3 is held inside the base 2. The upper mold 6 is located above the lower mold 3. The assembly also includes a pusher frame 8, an elastic element 9, and a guide seat. 10. Cam 11, mounting base 12 and motor 13. Mounting base 12 is installed on the top of the worktable 1. Motor 13 is installed on mounting base 12 by bolt connection. Cam 11 is installed on the output shaft of motor 13. Pusher frame 8 is slidably installed on both the left and right sides of worktable 1. Two elastic elements 9 are sleeved on pusher frame 8. The two ends of elastic elements 9 are connected to pusher frame 8 and worktable 1 respectively. Pusher frame 8 passes through base 2 and lower mold 3. Guide seat 10 is fixedly connected between the two pusher frames 8. Cam 11 can squeeze guide seat 10 to move when rotating.

[0023] See Figures 1-5 As shown, the bottom left and right sides of the workbench 1 are symmetrically fixed with foot pads.

[0024] See Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a limit block is fixedly connected to the top of the guide rod 4.

[0025] See Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, there are two reinforcing ribs that are fixedly connected between the base 2 and the workbench 1.

[0026] When using this device, place the part to be stamped on the lower die 3, then start the cylinder 7. The extension rod of the cylinder 7 extends and drives the slide 5 to slide downward along the four guide rods 4, so that the slide 5 drives the upper die 6 to move downward for stamping. After stamping is completed, control the extension rod of the cylinder 7 to retract and drive the slide 5 and the upper die 6 to reset. Then start the motor 13. The output shaft of the motor 13 drives the cam 11 to rotate and push the guide seat 10. The guide seat 10 drives the two pusher frames 8 to move upward synchronously. The elastic element 9 deforms accordingly, thereby pushing the forming piston out of the lower die 3, thus avoiding the forming piston from fitting too tightly with the lower die 3 and speeding up the output efficiency.

[0027] Example 2: Based on Example 1, refer to Figure 1 and Figure 4 As shown, it also includes electric guide rails 14, sliding frames 15, guide plates 16, limit seats 17, and mounting blocks 18. Four electric guide rails 14 are installed on both the base 2 and the slide 5. A sliding frame 15 is installed between the two electric sliders of two electric guide rails 14 located on the same side. Guide plates 16 are symmetrically fixed to both the front and rear sides of the base 2. The sliding frame 15 slides on the adjacent guide plates 16. Two mounting blocks 18 are welded to both the left and right sides of the lower mold 3 and the upper mold 6. Limit seats 17 are fixedly connected to the inner side of the sliding frame 15. The mounting blocks 18 are inserted into the adjacent limit seats 17.

[0028] Before stamping, the electric guide rail 14 is activated, which drives the electric slider to move the sliding frame 15 and the limit seat 17 outward. Then, the upper die 6 of the corresponding specification is inserted into the slide block 5, and the lower die 3 is inserted into the base 2. Then, the electric slider of the electric guide rail 14 is driven to move inward, which drives the sliding frame 15 and the limit seat 17 to move inward. This allows the limit seat 17 to be inserted into the mounting block 18 on the corresponding upper die 6 or lower die 3, thereby achieving the effect of quick assembly and disassembly of the upper and lower dies 3. This allows the corresponding upper and lower dies 3 to be replaced as needed, improving the practicality of the equipment.

[0029] See Figure 1 and Figure 5As shown, it also includes an image detector 19 and an alarm 20. The image detector 19 is installed on both the front and rear sides of the top of the base 2. The two image detectors 19 are located on the front and rear sides of the lower mold 3. The image detector 19 contains a control module. The alarm 20 is symmetrically installed on both the front and rear sides of the top of the base 2. The image detector 19 is electrically connected to the two adjacent alarms 20.

[0030] When the finished part is ejected, the image detector 19 performs defect detection on the finished part and transmits the detection data to the control module for analysis. When an abnormality is detected, the control module triggers the nearest alarm 20 to remind the operator to intervene and ensure processing quality.
