Description

Technical Field

[0001] This invention relates to the field of rubber parts manufacturing technology, specifically to a mold and cutting mechanism for rubber preforming. Background Technology

[0002] Currently, in the rubber product manufacturing industry, especially in large-scale rubber product companies, most rubber parts are produced by compression molding. During rubber compression molding, specific requirements must be placed on the weight, shape, and size of the raw materials, as these all affect the quality of the rubber products. The traditional method involves manually shaping the rubber raw material from the open mill into rectangular strips of 1000*200*10mm, then cutting them into smaller pieces of the required weight before adding the raw materials, and finally stacking them in the mold for vulcanization. However, this method results in high labor intensity for the operators.

[0003] Therefore, we proposed an integrated mold and cutting mechanism for rubber preforming, which can solve the problem of manual shearing and high labor intensity. However, when the rubber is extruded from the mold, the friction between the rubber and the inner wall of the mold generates high temperature, which can easily lead to the rubber becoming molten. Summary of the Invention

[0004] The purpose of this invention is to provide a rubber preforming mold and a cutting mechanism that are integrated to solve the problem mentioned in the background art, where the rubber is scalded due to the high temperature generated by the friction between the rubber and the inner wall of the mold during rubber extrusion.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rubber preforming mold and cutting integrated mechanism, including a mold, a cooling mechanism and a cutting mechanism;

[0006] The mold includes a shell and a core. The shell has a groove at its feed inlet for slidingly mounting the core. A disc-shaped pipe is provided inside the shell. The feed inlet of the shell is connected to the extruder head of an extruder. The shell is detachably mounted on the extruder head of the extruder. The disc-shaped pipe is connected to a first water pump. The inlet of the first water pump is connected to a water tank through a conduit. The water tank is located inside the cooling mechanism.

[0007] The cutting mechanism includes a cylinder, a cutter, and a support. The cylinder and the cutter are both mounted on the support. The telescopic end of the cylinder is fixedly connected to the cutter, and the support is fixedly connected to the side of the housing.

[0008] In one embodiment of the present invention, the cooling mechanism includes a cooling pool, a circulation pool, and a second water pump. The inlet of the second water pump is connected to the circulation pool, and the outlet of the second water pump is connected to the cooling pool. The cooling pool is located above the circulation pool and is connected to the circulation pool. The water tank is fixedly installed on the inner wall of the cooling pool.

[0009] In one embodiment of the present invention, a rotating shaft is rotatably installed inside the water tank, and one end of the rotating shaft passes through the side of the water tank. An impeller is keyed to the end of the rotating shaft that passes through the water tank. The blades of the impeller are directly opposite the outlet of the second water pump. A deflector is fixedly connected to the side wall of the rotating shaft, and the deflector is located inside the water tank.

[0010] The second water pump outputs water, which impacts the impeller, providing power for the impeller to rotate. The impeller drives the shaft to rotate, causing the baffle plate to rotate and stir the coolant.

[0011] In one embodiment of the present invention, a heat dissipation plate is fixedly connected to the side wall of the water tank, and the heat dissipation plate is located inside the cooling pool.

[0012] In one embodiment of the present invention, the dial plate has several through holes on its surface, there are at least three dial plates, and the dial plates are fixedly connected to the side wall of the rotating shaft in a ring array. The dial plates are made of aluminum plates.

[0013] In one embodiment of the present invention, the support member includes a support frame, a support plate, a pad, and a base plate. The support frame has a guide groove. A guide block for sliding within the guide groove is fixedly connected to the side of the cutter. The support plate is detachably mounted on the upper end of the support frame. The cylinder is detachably mounted on the support plate. The pad is fixedly connected to the support frame. A guide member is mounted on the base plate. The support frame is slidably mounted on the guide member. The base plate is fixedly connected to the housing. The support frame is located on one side of the discharge port of the housing. The pad is located below the cutter.

[0014] In one embodiment of the present invention, the guide member includes a baffle, a spring and a guide rod. The two ends of the spring are fixedly connected to the side of the baffle and the support frame, respectively. One end of the guide rod passes through the support frame and is slidably inserted into the housing. The baffle is fixedly connected to the bottom plate.

[0015] In one embodiment of the present invention, a strip groove is formed on the pad, a water wheel is installed in the strip groove, and a water trough is formed on the bottom plate, with the water wheel located in the water trough.

[0016] In one embodiment of the present invention, the inlet end of the water tank is connected to the outlet end of the disc-shaped pipe through an outlet pipe, and the outlet end of the water tank is connected to the water tank through a connecting pipe.

[0017] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this invention are:

[0018] 1. In this invention, by using a disc-shaped pipeline, a first water pump and a water tank, when the mold is working, the first water pump draws water from the water tank and sends it into the disc-shaped pipeline. The water comes into contact with the shell through the disc-shaped pipeline, which can exchange heat with the shell and reduce the temperature of the shell. This can cool down the high temperature generated by friction between the rubber and the inside of the shell during rubber extrusion, so that the rubber can remain fluid while preventing the rubber from becoming stale.

[0019] 2. In this invention, by using a cooling mechanism, the second water pump works to pump cooling water from the circulation pool into the cooling pool to cool the water tank. The water in the cooling pool flows into the circulation pool for cooling, and then circulates repeatedly, which can effectively cool the water tank and allow the cooling water to effectively cool the rubber inside the shell.

[0020] 3. In this invention, the water flowing out of the disc-shaped pipe comes into contact with the outside air through the cooperation of the water wheel and the water tank, so as to dissipate heat from the water. This allows the water flow to drive the water wheel to rotate, thereby removing the rubber that has been cut and placed on the pad.

[0021] 4. In this invention, the use of through holes can reduce the resistance of the agitator when stirring water, effectively preventing the impeller from failing to rotate due to excessive resistance; it can ensure that the agitator can stir the water normally; by setting the agitator as an aluminum plate, the part of the agitator that protrudes above the water surface is in contact with the air, which can play a role in heat dissipation.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific context of the specification.

[0032] Example 1

[0033] Please see Figures 1-6The present invention provides a rubber preforming mold 1 and a cutting mechanism, including mold 1, cooling mechanism and cutting mechanism 3;

[0034] Mold 1 includes a housing 4 and a mold core 5. The housing 4 has a groove 2 at its feed inlet for slidingly mounting the mold core 5. A disc-shaped pipe 6 is provided inside the housing 4. The feed inlet of the housing 4 is connected to the extruder head of the extruder. The housing 4 is detachably mounted on the extruder head of the extruder. The disc-shaped pipe 6 is connected to a first water pump 7. The liquid inlet of the first water pump 7 is connected to a water tank 8 through a conduit. The water tank 8 is located inside the cooling mechanism.

[0035] The cutting mechanism 3 includes a cylinder 9, a cutter 10, and a support member 11. The cylinder 9 and the cutter 10 are both mounted on the support member 11. The telescopic end of the cylinder 9 is fixedly connected to the cutter 10. The support member 11 is fixedly connected to the side of the housing 4.

[0036] It should be noted that the inlet end of the conduit is threaded with a frame containing a filter screen, which can filter the water entering the disc-shaped pipe 6 and effectively prevent foreign objects from entering the disc-shaped pipe 6 and causing blockage.

[0037] Using the above scheme, when the rubber material enters the housing 4 during extrusion, it is blocked by the die core 5, which can reduce the center pressure of the extruded material and balance the speed inside and outside the material block, thereby avoiding the expansion of the material block. With the use of the slide 2, the die core 5 can be installed and replaced quickly, and it is convenient for users to replace the die core when it is damaged. With the cooperation of the cylinder 9 and the cutter 10, the rubber extruded from the housing 4 can be cut.

[0038] By using the disc-shaped pipe 6, the first water pump 7, and the water tank 8, when the mold is working, the first water pump 7 draws water from the water tank 8 and sends it into the disc-shaped pipe 6. The water comes into contact with the shell 4 through the disc-shaped pipe 6, which can exchange heat with the shell 4 and reduce the temperature of the shell 4. This can cool down the high temperature generated by friction between the rubber and the inside of the shell 4 during rubber extrusion, so that the rubber can remain fluid while preventing the rubber from becoming stale.

[0039] Specifically, the cooling mechanism includes a cooling pool 14, a circulation pool 12, and a second water pump 13. The inlet of the second water pump 13 is connected to the circulation pool 12, and the outlet of the second water pump 13 is connected to the cooling pool 14. The cooling pool 14 is located above the circulation pool 12 and is connected to the circulation pool 12. The water tank 8 is fixedly installed on the inner wall of the cooling pool 14.

[0040] Using the above scheme, by using the cooling mechanism and the second water pump 13, the cooling water in the circulation pool 12 is pumped into the cooling pool 14 to cool the water tank 8. The water in the cooling pool 14 flows into the circulation pool 12 for cooling, and then circulates repeatedly, which can effectively cool the water tank 8 and allow the cooling water to effectively cool the rubber inside the shell 4.

[0041] Specifically, a rotating shaft 15 is rotatably installed inside the water tank 8, and one end of the rotating shaft 15 passes through the side of the water tank 8. An impeller 16 is keyed to the end of the rotating shaft 15 that passes through the water tank 8. The blades of the impeller 16 are directly opposite the outlet of the second water pump 13. A deflector 17 is fixedly connected to the side wall of the rotating shaft 15, and the deflector 17 is located inside the water tank 8.

[0042] By adopting the above scheme, when the second water pump 13 is working, the water pumped by the second water pump 13 impacts the impeller 16, causing the impeller 16 to rotate, thereby driving the rotating shaft 15 to rotate, which in turn causes the deflector plate 17 to rotate, so that the deflector plate 17 can stir the water in the water tank 8, making the water in the water tank 8 mixed and the water temperature in the water tank 8 uniform. This avoids the uneven temperature of the water pumped into the disc pipe 6 by the first water pump 7, which is not conducive to cooling the shell 4.

[0043] Specifically, a heat dissipation plate 18 is fixedly connected to the side wall of the water tank 8, and the heat dissipation plate 18 is located inside the cooling pool 14.

[0044] By adopting the above solution, the high temperature of the water tank 8 can be discharged through the use of the heat dissipation plate 18. Since the heat dissipation plate 18 is located in the cooling pool 14, it can better contact the cooling water and dissipate the heat more quickly. This allows the water in the water tank 8 to dissipate heat more quickly, thereby better cooling the rubber extruded from the shell 4.

[0045] Specifically, the dial plate 17 has several through holes 19 on its surface, and there are at least three dial plates 17. The dial plates 17 are fixedly connected to the side wall of the rotating shaft 15 in a ring array, and the dial plates 17 are made of aluminum plates.

[0046] By adopting the above solution and using through hole 19,

[0047] This can reduce the resistance of the agitator 17 when stirring the water, and effectively prevent the impeller 16 from failing to rotate due to excessive resistance.

[0048] This ensures that the agitator 17 can properly stir the water;

[0049] By setting the deflector plate 17 as an aluminum plate, the part of the deflector plate 17 that protrudes above the water surface and comes into contact with the air, which can play a role in heat dissipation.

[0050] Specifically, the support member 11 includes a support frame 20, a support plate 21, a pad 22, and a base plate 23. The support frame 20 has a guide groove 24. A guide block 25 for sliding within the guide groove 24 is fixedly connected to the side of the cutter 10. The support plate 21 is detachably mounted on the upper end of the support frame 20. The cylinder 9 is detachably mounted on the support plate 21. The pad 22 is fixedly connected to the support frame 20. A guide member 26 is mounted on the base plate 23. The support frame 20 is slidably mounted on... On the guide member 26, the bottom plate 23 is fixedly connected to the housing 4, the support frame 20 is located on one side of the discharge port of the housing 4, the pad plate 22 is located below the cutter 10, the guide member 26 includes a baffle 27, a spring 28 and a guide rod 29, the two ends of the spring 28 are fixedly connected to the baffle 27 and the side of the support frame 20 respectively, one end of the guide rod 29 passes through the support frame 20, and the guide rod 29 is slidably inserted into the housing 4, and the baffle 27 is fixedly connected to the bottom plate 23.

[0051] Using the above scheme, through the use of support member 11 and guide member 26, the rubber extruded from the shell 4 is cut by the cutter 10 driven by cylinder 9. When the cutter 10 contacts the rubber, the shell 4 is still discharging material. The extruded rubber squeezes the cutter 10. Under the squeezing action of the rubber, the spring 28 contracts, and the support frame 20 moves along the guide rod 29. After the cutting is completed, the cutter 10 returns to its original position, and the thrust disappears. Under the elastic recovery action of spring 28, the support frame 20 is pushed to return to its original position. This can prevent the cutter 10 from being damaged by the subsequently extruded rubber during the cutting process.

[0052] Specifically, a strip groove 30 is provided on the pad 22, and a water wheel 31 is installed in the strip groove 30. A water trough 32 is provided on the bottom plate 23, and the water wheel 31 is located in the water trough 32. The water inlet end of the water trough 32 is connected to the water outlet end of the disc-shaped pipe 6 through a water outlet pipe, and the water outlet end of the water trough 32 is connected to the water tank 8 through a connecting pipe.

[0053] Using the above scheme, the water flowing out of the disc-shaped pipe 6 comes into contact with the outside air through the cooperation of the water wheel 31 and the water tank 32, so as to dissipate heat from the water. The water flow can drive the water wheel 31 to rotate, remove the rubber that has been cut off and placed on the pad 22, and then the water enters the water tank 8 for heat dissipation.

[0054] It should be noted that the model and specifications of the first water pump 7, cylinder 9 and the second water pump 13 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0055] The power supply and operating principle of the first water pump 7, cylinder 9, and the second water pump 13 are clear to those skilled in the art and will not be described in detail here.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
