Technical Field

[0001] The utility model relates to the field of rubber molds, in particular to a rubber mold convenient for demolding. Background Technique

[0002] A stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly known as a cold punching die). Stamping is a pressure processing method that applies pressure to the material by using a die installed on a press at room temperature to cause separation or plastic deformation, so as to obtain the required parts.

[0003] When processing rubber products, a knife die is generally used. Due to the need for accessories such as stoppers, the productivity of the knife die is low. Therefore, in the prior art, a stamping die is generally used for processing. When the stamping die is used for stamping, the rubber raw material placed on the lower die is cooperated with the stamping hole by the stamping part for stamping. However, the product stamped out during the stamping process is likely to remain in the stamping hole, so further improvement and optimization are needed. Content of the Utility Model

[0009] Preferably, the lower slapping part is set as a plate-shaped part, the size of the lower slapping part is larger than that of the lower die, two groups of force concentrating parts are symmetrically arranged at the bottom of the lower slapping part, the force concentrating parts are integrally formed with the lower slapping part, and the force concentrating parts are all set as transverse strip-shaped parts with a triangular cross-section.

[0010] Preferably, push members are provided at the four upper corners of the lower pressing member. The push members are all arranged as vertical columnar members. Push grooves are correspondingly provided in the stamping holes for the push members. The push grooves are arranged as vertical grooves, and the upper ends of the push members all penetrate into the push grooves.

[0011] Preferably, lower push members are movably arranged at the inner bottoms of the push grooves. The sizes of the lower push members are all adapted to the push grooves. The bottoms of the lower push members are fixedly connected to the push members. The elastic force of the elastic member is greater than the frictional resistance between the lower push member and the damping member.

[0012] Preferably, installation grooves are provided at the upper ends of the push grooves, and plug members are arranged in the installation grooves. The plug members are arranged as disc-shaped members.

[0030] Embodiment 1

[0031] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a rubber mold facilitating demolding, including an upper mold 1 and a lower mold 2. A stamping part 4 is installed at the bottom of the upper mold 1, and a stamping hole 3 is arranged at the upper end of the lower mold 2:

[0032] A downward striking part 5 is located at the bottom of the upper mold 1. A force concentrating part 6 is arranged at the bottom of the downward striking part 5. The downward striking part 5 is used for striking the lower mold 2;

[0033] A pushing part 7 is located at the upper end of the downward striking part 5. A downward pushing part 9 is arranged at the upper end of the pushing part 7. The upper end of the downward pushing part 9 is fixedly connected with an elastic part 10. The elastic part 10 is used for pushing the downward striking part 5 to move downward;

[0034] An inserting part 11 is located inside the stamping hole 3. A vertical inserting plate 12 is arranged at the bottom of the inserting part 11. A damping part 13 is arranged inside the vertical inserting plate 12. The damping part 13 is used for damping the downward pushing part 9 when the upper mold 1 is lifted so that the distance between the downward striking part 5 and the lower mold 2 reaches the required height.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, the downward striking part 5 is set as a plate-shaped part. The size of the downward striking part 5 is larger than that of the lower mold 2. Two groups of force concentrating parts 6 are symmetrically arranged at the bottom of the downward striking part 5. The force concentrating parts 6 are integrally formed with the downward striking part 5. The force concentrating parts 6 are all set as transverse strip-shaped parts with a triangular cross-section. Four corners at the upper end of the downward striking part 5 are all provided with pushing parts 7. The pushing parts 7 are all set as vertical columnar parts. Push grooves 8 are correspondingly arranged inside the stamping hole 3 for the pushing parts 7. The push grooves 8 are set as vertical grooves. The upper ends of the pushing parts 7 all penetrate into the push grooves 8. The lower pushing parts 9 are movably arranged at the inner bottom of the push grooves 8. The sizes of the lower pushing parts 9 are all adapted to the push grooves 8. The bottoms of the lower pushing parts 9 are all fixedly connected with the pushing parts 7. The elastic force of the elastic part 10 is greater than the frictional resistance between the lower pushing part 9 and the damping part 13;

[0037] By means of the force - concentrating member 6 integrally formed with the downward - striking member 5, it is possible to prevent the force - concentrating member 6 from easily falling off during knocking. By means of the elastic member 10 cooperating with the downward - pushing member 9, when the upper die 1 is reset, the pushing member 7 can be pushed to move downward along the pushing groove 8, so that the downward - striking member 5 knocks the lower die 2.

[0038] Embodiment Three

[0039] On the basis of Embodiment Two, mounting grooves are arranged at the upper ends of the pushing grooves 8, and plug members 11 are arranged in the mounting grooves. The plug members 11 are arranged as disc - shaped members. At both ends of the bottom of the plug member 11, multiple groups of vertical inserting plates 12 are fixedly arranged at equal intervals in a circular shape. The vertical inserting plates 12 are all arranged as arc - shaped plate - like members. The bottoms of the vertical inserting plates 12 all penetrate into the pushing grooves 8. The inner sizes of the vertical inserting plates 12 are all adapted to the pushing grooves 8. At the inner sides of the bottoms of the vertical inserting plates 12, damping members 13 are fixedly connected. The damping members 13 are all arranged as arc - shaped members made of rubber material.

[0040] By means of the arranged damping members 13, the downward - pushing member 9 can be blocked during reset, so that the downward - pushing member 9 will not be immediately pushed downward by the elastic member 10. When the elastic member 10 slowly pushes the downward - pushing member 9 to leave the area of the damping member 13 and is no longer blocked by the damping member 13, the height between the downward - striking member 5 and the lower die 2 reaches the optimal striking height, making the striking effect of the downward - striking member 5 the best.

[0041] Embodiment Four

[0042] On the basis of Embodiment Three, rotary blocks 14 are movably arranged at the upper ends of the plug members 11. The rotary blocks 14 are all arranged as disc - shaped members. External threads are arranged on the outer sides of the rotary blocks 14. Internal threads corresponding to the rotary blocks 14 are arranged on the inner walls of the mounting grooves. The rotary blocks 14 are all screwed to the mounting grooves. At the upper ends of the rotary blocks 14, rotating columns 15 are fixedly connected. The rotating columns 15 are all arranged as column - shaped members. Vertical grooves are arranged at equal intervals in a circular shape on the outer sides of the rotating columns 15.

[0043] By means of the screwed rotary blocks 14, it is convenient to disassemble and assemble the plug members 11, and it is convenient to replace the damping members 13 when they are damaged, ensuring the striking effect.

[0044] When the present utility model is in use, when the upper die 1 pushes the stamping part 4 to stamp the rubber product on the lower die 2, the downward - striking member 5 pushes the downward - pushing member 9 to move upward through the pushing member 7, so that the damping member 13 is in contact with the downward - pushing member 9 to limit the downward - pushing member 9. When the upper die 1 is reset, the elastic member 10 pushes the downward - pushing member 9 to move downward through its own elastic force. The downward - pushing member 9 moves downward slowly. When the downward - pushing member 9 is no longer in contact with the damping member 13, the distance between the downward - striking member 5 and the lower die 2 reaches the optimal striking height. The elastic member 10 pushes the downward - striking member 5 to move downward through the downward - pushing member 9 to knock the lower die 2, causing the lower die 2 to vibrate and preventing the product after stamping from remaining in the stamping hole 3.
