Description

Technical Field

[0001] This utility model relates to the field of rubber molding technology, and more specifically, to an automatic lubrication mechanism for rubber pressing equipment. Background Technology

[0002] Rubber compression molding equipment is mainly used to process compounded rubber or recycled rubber into products of specific shapes through pressure, heating and other methods. It is suitable for producing rubber products such as seals and tire parts.

[0003] A search revealed CN220826223U, which discloses a rubber molding mechanism, including a feeding device. The feeding device has an extrusion device fixedly connected to its top. The feeding device includes a base with a groove in the middle. A sliding block is slidably connected within the groove. Fixed blocks are fixedly connected to both sides of the base. The extrusion device includes a support column. The bottom of the support column is fixedly connected to the base, and a second fixed plate is fixedly connected to its top. This invention, through the feeding device and extrusion device, ensures that the molded rubber material can be quickly removed, and also allows for rapid replacement of molds of different shapes to meet the production needs of different types of rubber products.

[0004] However, the aforementioned rubber molding equipment still has certain limitations in practical applications. Specifically, during the demolding stage, rubber products, after being heated and pressurized, tend to stick to the inner wall of the mold due to their still high surface tackiness. This adhesion makes it difficult to demold the product smoothly; if forcibly removed, it may deform before it has fully set. These problems not only increase operational difficulty but may also affect the dimensional accuracy of the product, ultimately negatively impacting overall production efficiency.

[0008] The lower mold mechanism is provided in two sets, and the inner surface of the bottom of the two sets of lower mold mechanisms is threadedly connected with threaded rods. A displacement motor is provided at the side end of the threaded rod, and the output end of the displacement motor is fixedly sleeved with the middle part of the threaded rod, and the outer surface is fixedly installed with the inner surface of the base plate.

[0009] Both sets of lower mold mechanisms include a lower mold. The surfaces of the lower mold near the base plate along its length are fixedly fitted with mating plates. A threaded column is fixedly fitted on the lower surface of the middle part of the lower mold. A connecting block is threadedly connected to the outer surface of the threaded column. The middle part of the connecting block is threadedly connected to the outer surface of the threaded rod. The outer surface of the connecting block is slidably installed with the inner surface of the middle part of the base plate.

[0010] The two sets of fixing mechanisms are symmetrically arranged about the centerline of the base plate and each includes a fixing plate. The lower surface of the fixing plate is fixedly installed on the upper surface of the middle part of the side of the base plate. An electric telescopic rod is fixedly installed on the side of the fixing plate away from the lower mold. A limit plate is fixedly installed at the end of the electric telescopic rod near the lower mold. Multiple T-shaped blocks are fixedly installed on the lower surface of the limit plate. The outer surfaces of the multiple T-shaped blocks are slidably installed with the inner wall of the middle part of the base plate. The middle part of the limit plate is engaged with the outer surface of the docking plate.

[0011] Both sets of lubrication mechanisms include a U-shaped frame. The lower surface of the U-shaped frame is fixedly installed on the upper surface of the base plate. A liquid tank is fixedly installed on the upper surface of the middle part of the U-shaped frame. A liquid pump is sleeved on the side of the liquid tank. A connecting pipe is sleeved on the bottom end of the liquid pump. Several nozzles are sleeved on the bottom of the connecting pipe. A cover box is fixedly installed on the lower surface of the top of the U-shaped frame. The outer surface of the bottom end of the nozzle is sleeved with the inner surface of the middle part of the cover box. A motor is fixedly installed on the side of the U-shaped frame. A circular plate is fixedly sleeved on the output end of the motor. A sponge roller is rotatably installed on the inner surface of the circular plate.

[0012] The upper surface at each of the four corners of the base plate is equipped with an air-cooled curing mechanism.

[0013] Each of the four sets of air-cooled curing mechanisms includes an electric telescopic rod II. The bottom of the electric telescopic rod II is bolted to the upper surface of the base plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above scheme, by setting up structures such as a displacement motor, a threaded rod, and a lubrication mechanism, after the pressing process is completed, the displacement motor is started, causing the threaded rod connected to the output end to rotate in the middle of the base plate. This pulls the connecting block connected to the threaded outer surface to move synchronously, driving the lower mold at the top to move. The lower mold containing the finished product is moved to the end of the base plate. At this time, the other lower mold without raw material can continue to carry out the pressing process, providing sufficient curing time for the lower mold containing the finished product and improving the product quality. In addition, during the process of the lower mold moving directly under the upper mold, the lubrication mechanism can be used to lubricate the surface of the moving lower mold, thereby reducing the wall adhesion between the finished product and the inner wall of the lower mold and improving the smoothness of subsequent demolding.

[0016] In the above scheme, by setting up an air-cooled curing mechanism, the lower mold containing the finished product can be controlled to assist in air cooling. Specifically, the electric telescopic rod II is controlled to reciprocate and extend. While the rack fixedly installed on its side slides against the inner surface of the limiting block, it drives the meshing gear to rotate back and forth. This causes the shaft connected in the middle of the gear and the bracket fixed on the top of the shaft to rotate back and forth alternately. At the same time, the motor II set on the top of the bracket drives the fan connected to the output end to rotate, thereby blowing laterally on the lower mold, assisting the finished product inside the lower mold to cool and solidify faster, which facilitates the release effect.

A fan 127 is fixedly sleeved at the output end of the motor 126.

[0032] The working process of this utility model is as follows:

[0033] When pressing rubber, the raw material is fed into the lower mold 70 by the feeding mechanism 5, and the lower mold 70 is adjusted to be directly below the upper mold 6. The lower mold mechanism 7 is limited and fixed by the fixing mechanism 10. Then, the rubber raw material is heated by the heating equipment, and the hydraulic cylinder 3 is controlled to push the pressing plate 4 to slide down along the outer surface of the main support 2, which drives the upper mold 6 connected to the bottom to press into the middle of the lower mold 70 to press the heated raw material.

[0034] After completing the above-mentioned pressing process, the upper mold 6, fixing mechanism 10 and other structures are reset, and then the displacement motor 8 is started, so that the threaded rod 9 connected to the output end rotates in the middle of the base plate 1, pulling the connecting block 73 connected to the outer surface threaded to move synchronously, driving the lower mold 70 at the top to move, and moving the lower mold 70 containing the finished product to the end of the base plate 1. At this time, the other lower mold 70 without raw material can continue to carry out the pressing process, providing sufficient curing time for the lower mold 70 containing the finished product, avoiding deformation of the finished product, and improving the quality of the product. In addition, during the process of the lower mold 70 moving to the lower mold 6, the lubrication mechanism 11 can be used to lubricate the surface of the moving lower mold 70, thereby reducing the wall adhesion between the finished product and the inner wall of the lower mold 70, and improving the smoothness of subsequent demolding.

[0035] The specific operation is as follows: when the lower mold 70 reaches below the U-shaped frame 110, the liquid pump 112 is first controlled to pump the lubricating oil inside the liquid tank 111 into the connecting pipe 113. The lubricating oil then flows through the connecting pipe 113 to several nozzles 114 and is sprayed onto the surface of the sponge roller 118 inside the cover box 115, where it is fully absorbed by the sponge roller 118. When the lower mold 70 reaches below the U-shaped frame 110, the motor 116 is controlled to rotate. The circular plate 117 connected to the output end of the motor 116 will rotate, causing the sponge roller 118, which is mounted on the circular plate 117 off-center, to rotate so that its outer surface is in contact with the surface of the lower mold 70. Then, as the lower mold 70 moves, the sponge roller 118 will rotate in contact with the surface of the lower mold 70 and apply the absorbed lubricating oil to the surface of the lower mold 70.

[0036] After the lower mold mechanism 7 moves directly below the upper mold 6, the position of the lower mold mechanism 7 can be limited by the fixing mechanism 10. Specifically, the electric telescopic rod 101 is extended, and the limiting plate 102 connected to its end is pushed towards the lower mold 70. The T-shaped block 103 connected to the bottom of the limiting plate 102 slides along the inner surface of the base plate 1 until the limiting plate 102 is aligned with the docking plate 71 and completely fits the docking plate 71. At this time, the limiting plate 102 completes the limiting treatment of the docking plate 71.

[0037] For the lower mold 70 containing the finished product, after it moves to the end of the bottom plate 1, the rubber finished product inside is in a natural cooling state. At this time, the air-cooling curing mechanism 12 can be controlled to assist the lower mold 70 containing the finished product in air cooling. Specifically, the electric telescopic rod 120 is controlled to reciprocate and extend. While the rack 121 fixedly installed on its side slides against the inner surface of the limiting block 123, it will drive the meshing gear 122 to reciprocate and rotate. This causes the shaft 124 connected to the middle of the gear 122 and the bracket 125 fixed on the top of the shaft 124 to rotate alternately. At the same time, the motor 126 set on the top of the bracket 125 will drive the fan 127 connected to the output end to rotate, thereby blowing the lower mold 70 laterally, assisting the finished product inside the lower mold 70 to cool and cure faster, which will improve the release effect.
