Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a gear and rack transmission manual press mold. Background Technology

[0002] Modern compression molds primarily use hydraulic cylinders to drive the upper mold, which is simple, direct, and easy to operate. However, hydraulic cylinders are bulky and expensive, making them a significant waste of resources for smaller molds. Furthermore, their large size and space requirements contradict the design principles of small compression molds.

[0003] Therefore, it is necessary to propose a gear and rack driven manual die pressing method. By using gear and rack drive, the use of hydraulic cylinders is eliminated, realizing manual die pressing and thus reducing costs and space occupation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a gear and rack drive manual mold pressing method. By using gear and rack drive, the use of a hydraulic cylinder is eliminated, realizing manual mold pressing and thus reducing costs and space occupation.

[0005] The purpose of this utility model is achieved through the following technical solution: a gear and rack driven manual press mold, including a base, an upper template and a lower template arranged parallel to each other on the base, at least one rack is arranged on the side of the upper template away from the lower template, at least one transmission rod parallel to the upper template is rotatably arranged above the upper template, a gear is rotatably arranged on the transmission rod, the gear meshes with the rack, and a manual component for driving its rotation is arranged on the transmission rod.

[0006] The lower template has two opposing base plates, the two ends of the transmission rod are rotatably connected to the base plates, and the upper template is slidably disposed with respect to the base plates.

[0007] The transmission rods are two in number, and the two transmission rods are located on both sides of the rack.

[0008] There are two racks, located at both ends of the upper template.

[0009] The lower template is provided with at least one guide post, the upper template is slidably sleeved on the guide post, and a return spring is sleeved on the guide post. The two ends of the return spring are respectively connected to the lower template and the upper template.

[0010] The manual assembly includes a hollow mother rod connected to a transmission rod. A daughter rod is slidably inserted through the end of the hollow mother rod away from the transmission rod. Multiple pressure blocks are slidably arranged in a ring around the daughter rod at the end of the hollow mother rod away from the transmission rod. The pressure blocks fit into the daughter rod. A ring sleeve is threaded and rotatably fitted on the end of the hollow mother rod away from the transmission rod. A wedge-shaped annular groove is formed on the inner wall of the ring sleeve. A compression spring is connected to the side of the pressure block away from the daughter rod. A wedge-shaped block matching the shape and size of the wedge-shaped annular groove is provided at the end of the compression spring away from the pressure block.

[0011] When the wedge block is located within the wedge-shaped ring groove, the compression spring is in its normal state.

[0012] The beneficial effects of this utility model are: by setting components such as gears, racks, and transmission rods, operators only need to operate the manual components to press down the upper template, thus making manual molding a reality, greatly reducing costs and space occupation.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and 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] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0019] A gear and rack driven manual pressing mold, reference Figures 1-3The system includes a base 1. An upper template 2 and a lower template 3, arranged parallel to each other, are mounted on the upper side of the base 1. Base plates 7 are mounted at both ends of the lower template 3, and the upper template 2 is slidably connected to the base plates 7 at both ends. Four guide posts 8 are mounted on the upper side of the lower template 3, and the upper template 2 is slidably fitted onto the four guide posts 8. Return springs 9 are mounted on the guide posts 8, and the two ends of the return springs 9 are connected to the upper template 2 and the lower template 3, respectively.

[0020] Two racks 4, positioned opposite each other, are provided on the upper side of the upper template 2. A transmission rod 5 is rotatably connected between the two base plates 7. The two transmission rods 5 are located on both sides of the racks 4. Two gears 6 are fixedly sleeved on the transmission rods 5, and the two gears 6 are respectively engaged with the two racks 4 one by one. In this embodiment, the gear 6 is half a piece, but it does not affect the transmission.

[0021] The transmission rod 5 is provided with threaded connecting posts 10. Both threaded connecting posts 10 extend upwards and face opposite directions. A manual component is detachably connected to the threaded connecting posts 10.

[0022] The operator holds the manual component, which rotates the transmission rod 5, causing the gear 6 to rotate. This, in turn, moves the rack 4 downward, pressing down the upper template 2 and compressing the return spring 9. After the pressing is complete, the operator releases the manual component, the return spring 9 returns to its original position, and the upper template 2 moves back to its original position.

[0023] The manual assembly includes a hollow female rod 11 detachably connected to a threaded connecting post 10. A male rod 12 is slidably inserted through the end of the hollow female rod 11 away from the threaded connecting post 10. Multiple pressure blocks 13 are slidably disposed on the upper wall of the end of the hollow female rod 11 away from the threaded connecting post 10. The multiple pressure blocks 13 are evenly distributed in a ring around the male rod 12. The pressure blocks 13 are in contact with the outer wall of the male rod 12. A ring sleeve 14 is threadedly fitted onto the end of the hollow female rod 11 away from the threaded connecting post 10. A wedge-shaped annular groove 15 is formed on the inner wall of the ring sleeve 14. A compression spring 16 is disposed on the side of the pressure block 13 away from the male rod 12, and a wedge-shaped block 17 matching the shape and size of the wedge-shaped annular groove 15 is disposed at the end of the compression spring 16.

[0024] When the length of the manual component needs to be adjusted, rotate the ring sleeve 14 so that the wedge block 17 is located in the wedge ring groove 15. At this time, the compression spring 16 is in the normal state, and the pressure block 13 does not apply pressure to the sub-rod 12. The sub-rod 12 can slide freely along the hollow mother rod 11. When the length of the manual component does not need to be adjusted, rotate the ring sleeve 14 so that the wedge block 17 is not located in the wedge ring groove 15. At this time, the compression spring 16 is in the compressed state, and the pressure block 13 applies pressure to the sub-rod 12. Under the pressure, the sub-rod 12 cannot slide freely along the hollow mother rod 11.

[0025] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the form disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above description or the technology or knowledge in related fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
