Description

Technical Field

[0001] This utility model relates to the field of hot pressing molding of rubber seals, and in particular to a high-precision hot pressing molding device for rubber seals. Background Technology

This invention, by setting up a protective box, reduces the risk of burns caused by workers accidentally touching the mold or hot press head during the processing of rubber seals. Furthermore, after the rubber seal is processed, the mold can be removed from the protective box, and an electric ejector rod can drive an ejector rod to eject the molded rubber seal from the mold cavity, thus facilitating material demolding and improving processing efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a high-precision hot-press molding device for rubber seals, including a workbench 1, a hot press 2 fixedly connected to the top of the workbench 1, a hot press mold 5 set on the top of the workbench 1, a feeding mechanism 3 and a conveying mechanism 4 set on the workbench 1, the feeding mechanism 3 including a support frame 311, the bottom of the support frame 311 fixedly connected to the top of the workbench 1, a screw 312 rotatably connected to the inner wall of the support frame 311, the screw 312 rotates under the drive of a motor 324 to realize the translation of a crossbeam 314, a limit rod 313 fixedly connected to the inner wall of the support frame 311, the limit rod 313 is used to limit the movement direction of the crossbeam 314, so that it can only translate along the axial direction of the screw 312, one end of the crossbeam 314 is threadedly connected to the outer wall of the screw 312, the crossbeam 314 realizes translation under the rotation of the screw 312, and the crossbeam 314... 14 The other end is slidably connected to the outer wall of the limiting rod 313 to ensure the stability of the translation of the crossbeam 314. The bottom of the crossbeam 314 is rotatably connected to the storage cylinder 315, which is used to store granular rubber raw materials. The top of the crossbeam 314 is fixedly connected to the motor 316. The bottom end of the output shaft of the motor 316 is fixedly connected to the top of the storage cylinder 315. The motor 316 can drive the storage cylinder 315 to rotate, so that the bottom outlet of the discharge cylinder 319 can draw a circle with the center of the hot press mold 5 as the axis to uniformly distribute the material. The outer wall of the storage cylinder 315 is fixedly connected to the diaphragm pump 317, which is used to extract the granular rubber raw materials inside the storage cylinder 315. One end of the conveying pipe 318 is fixedly connected to the outer wall of the diaphragm pump 317, and the other end of the conveying pipe 318 is fixedly connected to the discharge cylinder 319. The conveying pipe 318 is used to transport the extracted raw materials into the discharge cylinder 319.

[0032] Reference Figures 1-3The feeding mechanism 3 also includes a support plate 320, which is fixedly connected to the bottom of the storage cylinder 315. A limiting groove 321 is formed on the inner wall of the support plate 320, providing a sliding track for the slider 322. The feeding mechanism 3 also includes a slider 322, whose outer wall is slidably connected to the inner wall of the limiting groove 321. Driven by the electric actuator 323, it moves the discharge cylinder 319. The inner wall of the slider 322 is fixedly connected to the outer wall of the discharge cylinder 319, thus adjusting the position of the discharge cylinder 319. The feeding mechanism 3 also includes an electric actuator. The push rod 323 is fixedly connected to the outer wall of the slider 322. By extending and retracting the inner rod, the slider 322 is pushed, thereby changing the position of the bottom outlet of the discharge cylinder 319 to adapt to the hot press mold 5 with different diameter mold cavities. The feeding mechanism 3 also includes a second motor 324. The outer wall of the second motor 324 is fixedly connected to the left side of the support frame 311. The output end of the second motor 324 is fixedly connected to the left end of the screw 312 to provide power for the rotation of the screw 312, so that the crossbeam 314 drives the storage cylinder 315 to move to the center position of the hot press mold 5.

[0033] Reference Figure 4 The conveying mechanism 4 includes a motor 411, the bottom of which is fixedly connected to the top of the discharge cylinder 319 to provide power for the rotation of the rotating rod 412. The output end of the motor 411 is fixedly connected to the rotating rod 412, which drives the stirring rod 413 and the conveying blade 414 to rotate. The conveying mechanism 4 also includes a stirring rod 413, the outer wall of which is fixedly connected to the outer wall of the top of the rotating rod 412 to stir the raw material inside the discharge cylinder 319, preventing the granular rubber raw material from accumulating and clumping, and keeping the raw material in good flowability and uniformity. The conveying mechanism 4 also includes a conveying blade 414, the outer wall of which is fixedly connected to the outer wall of the bottom end of the rotating rod 412 to uniformly discharge the granular raw material to the inner wall of the mold groove of the hot pressing mold 5.

[0034] Working principle: During the hot pressing of the rubber seal, motor 324 drives the fixedly connected screw 312 to rotate. Under the limiting action of limit rod 313, the crossbeam 314 threaded to the outer wall of screw 312 moves horizontally, causing the storage cylinder 315 to move to the center position of the hot pressing mold 5. Then, by starting diaphragm pump 317, the diaphragm pump 317 draws out the granular rubber raw material inside the storage cylinder 315, and then transports it to the discharge cylinder 319 through conveying pipe 318. By starting the motor 411, the output end of the motor 411 drives the fixedly connected rotating rod 412 to rotate, which in turn drives the stirring rod 413 and the conveying blade 414 fixedly connected to the outer wall of the rotating rod 412 to rotate. The stirring rod 413 can stir the raw material inside the discharge cylinder 319 to prevent the granular rubber raw material from accumulating and clumping in the discharge cylinder 319, so that the raw material maintains good fluidity and uniformity. The conveying blade 414 can discharge the granular raw material evenly, so that the granular raw material falls on the inner wall of the mold groove opened on the hot press mold 5.

[0035] When the granular raw material is discharged, the motor 316 is started, and the output shaft of the motor 316 drives the fixedly connected storage cylinder 315 and support plate 320 to rotate. This causes the discharge port at the bottom of the discharge cylinder 319 to draw a circle with the center of the hot press mold 5 as the axis, so that the raw material can be evenly added into the mold cavity of the hot press mold 5 without manual addition. This avoids the tedious operation of manual addition of raw materials, and enables continuous and stable feeding, which greatly shortens the feeding time and improves the overall production efficiency of rubber seals. Then, the hot press mold 5 can be pushed into the hot press machine 2 for hot pressing molding of rubber seals.

[0036] When hot pressing a hot press mold 5 with mold cavities of different diameters, by activating the electric push rod 323, the inner rod of the electric push rod 323 pushes the slider 322 to slide on the inner wall of the limiting groove 321, thereby changing the position of the bottom discharge port of the discharge cylinder 319 to adapt to hot press molds 5 with mold cavities of different diameters. There is no need to equip molds of different specifications with special feeding equipment, which improves the versatility and flexibility of the equipment.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
