Abstract
Description
Technical Field
[0001] This utility model relates to the field of sleeve processing technology, and in particular to a sleeve forming mold with a protective structure. Background Technology
[0002] Sleeve processing refers to a series of processing steps performed on a sleeve to meet design requirements and usage standards. A sleeve is a part with a hollow tubular structure, usually made of metal or plastic materials, and is widely used in the electronics, electrical appliances, machining and automotive industries.
[0003] In the production process of sleeves, the forming mold is a key piece of equipment. In the existing technology, traditional forming molds lack components to protect operators during use. When the forming mold is in use, some material will be squeezed out from the gaps in the mold. When the pressure of the material being squeezed out is high, it may cause the already formed or partially formed workpiece to splash out. Without effective blocking measures, the material and workpiece are more likely to overflow and splash from the edge of the mold, thereby causing injury to the operator. The safety is insufficient. Therefore, it is necessary to redesign a sleeve forming mold with a protective structure to address the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sleeve forming mold with a protective structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A sleeve forming mold with a protective structure includes a base. A lower mold is fixedly mounted on the upper surface of the base via a mounting seat. An upper top plate and a connecting plate are slidably mounted on the outer wall of the lower mold. The upper surface of the connecting plate is connected to the bottom wall of the upper top plate via a buffer mechanism. Two movable grooves are formed on the upper surface of the base. Connecting blocks are fixedly connected to the inner walls of both movable grooves via telescopic mechanisms. First connecting frames are fixedly mounted on the upper surfaces of both connecting blocks. Second connecting frames are rotatably connected to the interiors of both first connecting frames via connecting mechanisms. The outer walls of both second connecting frames are fixedly connected to the bottom wall of the connecting plate. A support frame is fixedly mounted on the upper surface of the base via a support cover. A hydraulic cylinder is fixedly installed inside the support frame. A pressing plate is fixedly connected to the telescopic end of the hydraulic cylinder. A connecting shaft is fixedly installed on the upper surface of the base through a connecting opening. A baffle is slidably installed on the outer wall of the connecting shaft. A movable opening that mates with the connecting shaft is opened on the outer wall of the baffle. A first connecting frame is fixedly installed on the bottom wall of the baffle. A screw is rotatably installed on the inner bottom wall of the base through a movable frame. A motor that mates with the screw is fixedly installed on the outer wall of the movable frame. A movable block is threadedly installed on the outer wall of the screw through a limiting mechanism. A second connecting frame is fixedly installed on the upper surface of the movable block. A connecting plate is rotatably installed inside the second connecting frame. The end of the connecting plate is rotatably connected to the inside of the first connecting frame.
[0007] Preferably, the buffer mechanism includes two spring telescopic rods fixedly installed on the upper surface of the connecting plate, and the telescopic ends of the two spring telescopic rods are fixedly connected to the bottom wall of the upper top plate.
[0008] Preferably, the telescopic mechanism includes an electric actuator fixedly installed inside the movable slot, and the telescopic end of the electric actuator is fixedly connected to the outer wall of the connecting block.
[0009] Preferably, the connecting mechanism includes a connecting rod rotatably mounted inside the first connecting frame, and the end of the connecting rod is rotatably connected to the inside of the second connecting frame.
[0010] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the movable frame, the limiting rod sliding through the movable block.
[0011] Preferably, both the outer and inner walls of the baffle are provided with observation openings, and each of the two observation openings is fixedly equipped with an observation window.
[0012] The beneficial effects of this utility model are:
[0013] 1. By setting up components such as connecting plates, connecting shafts, and baffles, as the screw continues to rotate, the second connecting frame can push the first connecting frame through the connecting plate. This allows the first connecting frame to drive the baffle to slide on the outer wall of the connecting shaft through the moving opening, thereby causing the baffle to extend from inside the base and be in a vertical position. At this time, the baffle can cooperate with the support cover to shield the processing area and prevent the workpiece from being thrown outward under force, thus achieving safety protection for the operator.
[0014] 2. By setting up components such as electric push rods, connecting rods and upper top plates, the electric push rods on both sides can drive the connecting blocks on the same side to move respectively. This allows the two first connecting frames to push the second connecting frames on the same side through the cooperation of the connecting rods. In turn, the two second connecting frames can jointly drive the upper top plate to move upward through the cooperation of the connecting plate and the spring telescopic rod, so that the upper top plate can push the formed sleeve out from the outer wall of the lower mold, achieving convenient demolding.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5 A sleeve forming mold with a protective structure includes a base 1. A lower mold 3 is fixedly installed on the upper end face of the base 1 via a mounting seat 2. An upper top plate 4 and a connecting plate 5 are slidably installed on the outer wall of the lower mold 3. The upper end face of the connecting plate 5 is connected to the bottom wall of the upper top plate 4 via a buffer mechanism. The buffer mechanism includes two spring telescopic rods 6 fixedly installed on the upper end face of the connecting plate 5. The telescopic ends of the two spring telescopic rods 6 are fixedly connected to the bottom wall of the upper top plate 4. Two moving grooves are opened on the upper end face of the base 1. The inner walls of the two moving grooves are fixedly connected to connecting blocks 8 via telescopic mechanisms. The telescopic mechanism includes an electric push rod 7 fixedly installed inside the moving groove. The telescopic end of the electric push rod 7 is fixedly connected to the outer wall of the connecting block 8.
[0023] Two connecting blocks 8 are each fixedly mounted with a first connecting frame 9. The two first connecting frames 9 are each rotatably connected to a second connecting frame 11 through a connecting mechanism. The connecting mechanism includes a connecting rod 10 rotatably mounted inside the first connecting frame 9. The end of the connecting rod 10 is rotatably connected to the inside of the second connecting frame 11. The outer walls of the two second connecting frames 11 are fixedly connected to the bottom wall of the connecting plate 5. The upper surface of the base 1 is fixedly mounted with a support frame 13 through a support cover 12. The support frame 13 is fixedly mounted with a hydraulic cylinder 14 inside. The telescopic end of the hydraulic cylinder 14 is fixedly connected with a pressing plate 15. The upper surface of the base 1 is fixedly mounted with a connecting shaft 16 through a connecting opening. A baffle 17 is slidably mounted on the outer wall of the connecting shaft 16. Both the outer and inner walls of the baffle 17 have observation openings. Both observation openings have observation windows fixedly mounted inside.
[0024] The outer wall of the baffle 17 has a movable opening that mates with the connecting shaft 16. The bottom wall of the baffle 17 is fixedly mounted with a first connecting frame 18. The inner bottom wall of the base 1 is rotatably mounted with a screw 20 via a movable frame 19. The outer wall of the movable frame 19 is fixedly mounted with a motor 21 that mates with the screw 20. The outer wall of the screw 20 is threadedly mounted with a moving block 23 via a limiting mechanism. The limiting mechanism includes a limiting rod 22 fixedly mounted inside the movable frame 19. The limiting rod 22 slides through the moving block 23. The upper end face of the moving block 23 is fixedly mounted with a second connecting frame 24. The second connecting frame 24 is rotatably mounted with a connecting plate 25. The end of the connecting plate 25 is rotatably connected to the inside of the first connecting frame 18.
[0025] In use, the pipe fitting can be first fitted onto the outer wall of the lower mold 3. Before forming the sleeve, the motor 21 can drive the screw 20 to rotate. When the screw 20 rotates, it can move the moving block 23 through the cooperation of the limiting rod 22. At this time, the moving block 23 can move the second connecting frame 24. Thus, the second connecting frame 24 can push the first connecting frame 18 through the connecting plate 25, thereby allowing the first connecting frame 18 to drive the baffle 17 to slide on the outer wall of the connecting shaft 16 through the moving opening. As the screw 20 continues to rotate, the baffle 17 can extend from the inside of the base 1 and be in a vertical state (e.g., Figure 1As shown), at this time, the baffle 17 can cooperate with the support cover 12 to shield the processing area and prevent the workpiece from being thrown outward under force, thereby achieving safety protection for the operator.
[0026] Next, the operator can observe the inside of the baffle 17 through the observation window. During the forming of the sleeve, the telescopic end of the hydraulic cylinder 14 can drive the extrusion plate 15 to move downward, thereby allowing the extrusion plate 15 to extrude the upper end face of the tube, causing the tube to slide downward on the outer wall of the lower mold 3 and be formed. During the forming of the tube, it can extrude the upper end face of the upper top plate 4. The force on the upper top plate 4 can extrude the two spring telescopic rods 6, thereby buffering the force on the upper top plate 4 and preventing it from being damaged by extrusion. At the same time, it can also avoid affecting the forming of the sleeve. When it is necessary to demold the sleeve, the motor 21 can drive the screw 20 to rotate. The baffle 17 can slide on the outer wall of the connecting shaft 16 and move into the base 1 to release the obstruction. Then, the hydraulic cylinder 14 can drive the extrusion plate 15 to move upward and reset. Immediately afterwards, the electric push rods 7 on both sides can drive the connecting blocks 8 on the same side to move respectively. At this time, the two connecting blocks 8 can drive the first connecting frame 9 on the same side to move respectively. Thus, the two first connecting frames 9 can push the second connecting frame 11 on the same side through the cooperation of the connecting rod 10. Thus, the two second connecting frames 11 can drive the upper top plate 4 to move upward through the cooperation of the connecting plate 5 and the spring telescopic rod 6, so that the upper top plate 4 can push the formed sleeve out from the outer wall of the lower mold 3, realizing its convenient demolding.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
