Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold device with a material discharge buffer function. Background Technology

[0002] Injection molding is a method of shaping industrial workpieces. Workpieces are usually made of rubber or plastic. Injection molding machines (also known as injection molding machines or injection molding machines) are the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting materials. In traditional injection molds, after injection molding is completed, the workpiece falls directly into the inside of the collection device after being removed from the mold. Due to the lack of cushioning, the workpiece falling from a height is easily damaged by impact. In order to reduce workpiece damage, an injection mold device with a material dropping cushioning function has been proposed.

[0003] For example, the injection mold device with material feeding buffer function disclosed in the authorization announcement number CN222844675U includes a support base, a first connecting base fixedly connected to the top of the support base, a first module installed on the first connecting base, a movable structure provided at the top of the support base, a second module installed on the movable structure, a material ejection structure provided on the second module, a buffer structure provided on the support base, the buffer structure including a connecting frame and a connecting shaft, a connecting frame fixedly connected to the support base, a connecting shaft fixedly connected to the connecting frame, a connecting rod rotatably connected to the connecting shaft, a connecting sleeve slidably connected to the connecting rod, a spring provided inside the connecting sleeve, the connecting sleeve rotatably connected to a guide plate, the guide plate rotatably connected to the connecting frame, and a collecting structure provided at the bottom of the support base;

[0004] While it facilitates the cushioning of falling rubber workpieces, thereby preventing damage and effectively improving safety, it does not solve the problem that existing injection mold devices are not conducive to the linkage elasticity to offset the impact force when the workpiece falls, nor to multi-stage material drop cushioning, which affects the yield rate of the workpiece. Utility Model Content

[0005] The purpose of this invention is to provide an injection mold device with a material dropping buffer function, so as to solve the problem mentioned in the background art that the injection mold device is not convenient for linkage elasticity to offset the impact force when the workpiece falls, which is not conducive to multi-stage material dropping buffering and affects the yield of the workpiece.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an injection mold device with a material feeding buffer function, comprising a support frame and a limiting frame. The top of the support frame is provided with a limiting frame, and a support arm is provided on the side wall of the support frame. A hydraulic cylinder is provided inside the limiting frame, and a right mold is provided at the output end of the hydraulic cylinder. The right mold is slidably connected to the limiting frame. A left mold is provided on the surface of the limiting frame on one side of the right mold, and the left mold is fixedly connected to the limiting frame. A material box is slidably provided inside the support frame, and a top plate is provided inside the material box. The top plate is slidably connected to the material box. Multiple sets of damping slide rods with equal spacing are provided at the bottom end of the top plate. A left movable sleeve and a right movable sleeve are respectively provided at both ends of the support arm.

[0007] Preferably, a left movable rod is movably disposed inside the left movable sleeve, and a left torsion spring is disposed on the surface of the left movable rod, with the two ends of the left torsion spring connected to the left movable rod and the left movable sleeve respectively.

[0008] Preferably, one end of the left movable rod is provided with a left linkage arm, and the other end of the left movable rod is provided with a left receiving plate.

[0009] Preferably, a connecting rod is provided at the end of the left linkage arm away from the left movable rod, and a left hinge shaft is provided at the end of the connecting rod near the left linkage arm, and the connecting rod is movably connected to the left linkage arm through the left hinge shaft.

[0010] Preferably, a right linkage arm is provided at the end of the connecting rod away from the left linkage arm, and a right hinge shaft is provided at the end of the right linkage arm near the connecting rod, and the right linkage arm is movably connected to the connecting rod through the right hinge shaft.

[0011] Preferably, the right movable sleeve has a right movable rod inside, and the right movable rod is connected to the right linkage arm.

[0012] Preferably, a right torsion spring is fitted on the surface of the right movable rod, and the two ends of the right torsion spring are respectively connected to the right movable sleeve and the right movable rod, and a right receiving plate is provided at the end of the right movable rod away from the right movable sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the injection mold device not only realizes the linkage elasticity to offset the impact force when the workpiece falls, which facilitates multi-stage material dropping buffering, but also improves the yield of the workpiece.

[0014] (1) The hydraulic cylinder drives the right mold to slide on the surface of the limit frame, so that the left mold contacts the right mold and closes with the right mold. The raw material is injected into the mold after the mold is closed through the injection hole inside the left mold. After the injection is completed, the mold is opened and the workpiece falls out of the mold. During the falling process, the workpiece will touch the left receiving plate. The weight of the workpiece will drive the left receiving plate to rotate. The left receiving plate will drive the left movable rod to rotate inside the left movable sleeve. The left movable rod will drive the left torsion spring to deform and contract. The left movable rod will drive the left linkage arm to rotate. The left linkage arm will drive the connecting rod to rotate through the left hinge shaft. The connecting rod will drive the right linkage arm to rotate through the right hinge shaft. The right linkage arm will drive the right movable rod to rotate inside the right movable sleeve. The right movable rod will drive the right torsion spring to deform and contract. When the spring contracts, the right movable rod drives the right receiving plate to rotate. The left and right receiving plates rotate in opposite directions. This rotation has the advantage of preventing the right receiving plate from remaining stationary while the left receiving plate rotates, thus preventing material from getting stuck between the left and right receiving plates. At the same time, with the elastic cooperation of the left and right torsion springs, the impact force on the left and right receiving plates is buffered and offset, thereby preventing the workpiece from falling directly and being damaged by collision. After the workpiece falls, the left and right torsion springs respectively drive the left and right receiving plates to reset, preparing for the subsequent workpiece unloading. This linkage elasticity offsets the impact force when the workpiece falls, facilitating the initial unloading buffer of the workpiece, preventing the workpiece from being bumped, and improving the workpiece yield.

[0015] (2) The workpiece falls from between the left receiving plate and the left hinge shaft into the interior of the top plate. The workpiece drives the top plate to move downward, and the top plate drives the damping slide rod to retract. With the cooperation of multiple sets of damping slide rods, the impact force of the workpiece is offset twice, so that the workpiece falls smoothly onto the surface of the top plate. When there are many workpieces on the surface of the top plate, the material box is pulled out from the inside of the support frame and the workpiece is transferred to another position. Then the material box is placed back into the inside of the support frame to continue receiving workpieces. This facilitates the secondary buffering and offsetting of the workpiece and facilitates the batch transfer of workpieces. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 An embodiment of this utility model provides: an injection mold device with a material dropping buffer function, including a support frame 1 and a limiting frame 6. The top of the support frame 1 is provided with a limiting frame 6, and a support arm 7 is provided on the side wall of the support frame 1. A hydraulic cylinder 5 is provided inside the limiting frame 6. A right mold 4 is provided at the output end of the hydraulic cylinder 5, and the right mold 4 is slidably connected to the limiting frame 6. A left mold 3 is provided on the surface of the limiting frame 6 on one side of the right mold 4, and the left mold 3 is fixedly connected to the limiting frame 6. A material box 2 is slidably provided inside the support frame 1. A top plate 8 is provided inside the material box 2, and the top plate 8 is slidably connected to the material box 2. Multiple sets of damping slide rods 9 with equal spacing are provided at the bottom end of the top plate 8. A left movable sleeve 12 and a right movable sleeve 18 are respectively provided at both ends of the support arm 7.

[0024] When injection molding is required, hydraulic cylinder 5 is opened, causing the right mold 4 to slide on the surface of the limit frame 6, so that the left mold 3 contacts the right mold 4 and closes with it. The raw material is injected into the closed mold through the injection hole inside the left mold 3. After injection molding is completed, the mold is opened, and the workpiece falls out of the mold. During the fall, the workpiece touches the left receiving plate 11. The weight of the workpiece causes the left receiving plate 11 to rotate, which in turn causes the left movable rod 14 to rotate inside the left movable sleeve 12. The left movable rod 14 causes the left torsion spring 13 to deform and contract, which in turn causes the left movable rod 14 to rotate the left linkage arm 15. The left linkage arm 15 drives the connecting rod 10 to rotate through the left hinge shaft 20. The connecting rod 10 drives the right linkage arm 16 to rotate through the right hinge shaft 21. The right linkage arm 16 drives the right movable rod 19 to rotate inside the right movable sleeve 18. The right movable rod 19 drives the right linkage arm 19 to rotate inside the right movable sleeve 18. The deformation of the right torsion spring 17 causes it to contract, which in turn drives the right receiving plate 22 to rotate via the right movable rod 19. The left receiving plate 11 and the right receiving plate 22 rotate in opposite directions. This rotation is beneficial because it prevents the right receiving plate 22 from remaining stationary while the left receiving plate 11 rotates, thus preventing material from getting stuck between them. At the same time, the elastic cooperation of the left torsion spring 13 and the right torsion spring 17 buffers and offsets the impact force on the left receiving plate 11 and the right receiving plate 22, thereby preventing the workpiece from falling directly and getting damaged. After the workpiece falls, the left torsion spring 13 and the right torsion spring 17 respectively drive the left receiving plate 11 and the right receiving plate 22 to reset, preparing for subsequent workpiece unloading. This achieves linkage and elastic offsetting of the impact force when the workpiece falls, facilitating the initial unloading buffering of the workpiece, preventing workpiece from being bumped, and improving the workpiece yield.

[0025] The left movable sleeve 12 is internally provided with a left movable rod 14, and the surface of the left movable rod 14 is provided with a left torsion spring 13, and the two ends of the left torsion spring 13 are respectively connected to the left movable rod 14 and the left movable sleeve 12.

[0026] A left linkage arm 15 is provided at one end of the left movable rod 14, and a left receiving plate 11 is provided at the other end of the left movable rod 14. A connecting rod 10 is provided at the end of the left linkage arm 15 away from the left movable rod 14. A left hinge shaft 20 is provided at the end of the connecting rod 10 near the left linkage arm 15, and the connecting rod 10 is movably connected to the left linkage arm 15 through the left hinge shaft 20. A right linkage arm 16 is provided at the end of the connecting rod 10 away from the left linkage arm 15. A right hinge shaft 21 is provided at the end of the right linkage arm 16 near the connecting rod 10, and the right linkage arm 16 is movably connected to the connecting rod 10 through the right hinge shaft 21.

[0027] The right movable sleeve 18 is internally provided with a right movable rod 19, and the right movable rod 19 is connected to the right linkage arm 16. The surface of the right movable rod 19 is fitted with a right torsion spring 17, and the two ends of the right torsion spring 17 are respectively connected to the right movable sleeve 18 and the right movable rod 19. The end of the right movable rod 19 away from the right movable sleeve 18 is provided with a right receiving plate 22.

[0028] The workpiece falls from between the left receiving plate 11 and the left hinge shaft 20 into the interior of the top plate 8. The workpiece drives the top plate 8 to move downwards, and the top plate 8 drives the damping slide rod 9 to retract. With the cooperation of multiple sets of damping slide rods 9, the impact force of the workpiece is offset a second time, so that the workpiece falls smoothly onto the surface of the top plate 8. When there are many workpieces accumulating on the surface of the top plate 8, the material box 2 is pulled out from the inside of the support frame 1, and the workpieces are transferred to other positions. Then the material box 2 is placed back into the inside of the support frame 1 to continue receiving workpieces. This facilitates the secondary buffering and offsetting of the workpieces and the batch transfer of workpieces.

[0029] Working principle: When injection molding is required, the hydraulic cylinder 5 drives the right mold 4 to slide on the surface of the limit frame 6, so that the left mold 3 contacts the right mold 4 and closes with the right mold 4. The raw material is injected into the closed mold through the injection hole inside the left mold 3. After injection molding is completed, the mold is opened and the workpiece falls out of the mold. During the falling process, the workpiece will touch the left receiving plate 11. The weight of the workpiece will drive the left receiving plate 11 to rotate. The left receiving plate 11 drives the left movable rod 14 to rotate inside the left movable sleeve 12. The left movable rod 14 drives the left torsion spring 13 to deform. The left torsion spring 13 contracts, causing the left movable rod 14 to drive the left linkage arm 15 to rotate. The left linkage arm 15, through the left hinge shaft 20, drives the connecting rod 10 to rotate. The connecting rod 10, through the right hinge shaft 21, drives the right linkage arm 16 to rotate. The right linkage arm 16 drives the right movable rod 19 to rotate inside the right movable sleeve 18. The right movable rod 19 causes the right torsion spring 17 to deform and contract. The right movable rod 19 then drives the right receiving plate 22 to rotate. The left receiving plate 11 and the right receiving plate 22 rotate in opposite directions. The advantage of this rotation is to avoid... When the left receiving plate 11 rotates, the right receiving plate 22 remains stationary to prevent material from getting stuck between the left and right receiving plates 11 and 22. Simultaneously, the elastic cooperation of the left and right torsion springs 13 and 17 buffers and offsets the impact force on the left and right receiving plates 11 and 22, thus preventing the workpiece from falling directly and causing damage. After the workpiece falls, the left and right torsion springs 13 and 17 respectively drive the left and right receiving plates 11 and 22 to reset, preparing for subsequent workpiece unloading. The workpiece falls between plates 22 into the interior of the top plate 8. The top plate 8 moves downward, and the top plate 8 causes the damping slide rods 9 to retract. With the cooperation of multiple sets of damping slide rods 9, the impact force of the workpiece is offset a second time, so that the workpiece falls smoothly onto the surface of the top plate 8. When there are many workpieces on the surface of the top plate 8, the material box 2 is pulled out from the inside of the support frame 1, and the workpieces are transferred to other positions. Then the material box 2 is placed back into the inside of the support frame 1 to continue receiving workpieces. The above is the complete usage of the injection mold device with material dropping buffer function.
