DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0026] The present application provides a technical solution:

[0027] Please refer to Figures 1 to 4A rubber shock-absorbing pad extrusion molding equipment with auxiliary cooling includes an extrusion device body 1, a lifting plate 5 installed inside the extrusion device body 1, an upper mold 6 provided at the bottom of the lifting plate 5, a lower mold assembly 3 provided below the upper mold 6, and a cooling assembly 4 provided on one side of the lower mold assembly 3. The cooling assembly 4 includes a cooling water tank 405 fixed inside the extrusion device body 1, and the telescopic end of an extrusion hydraulic cylinder 7 fixed above the lifting plate 5.

[0028] The lower die assembly 3 includes a lower die chamber 301. A rotating plate 304 is provided on one side of the lower die chamber 301, and the lower die chamber 301 is rotatably installed inside the extrusion device body 1 via the rotating plate 304. A support plate 305 is provided on the other side of the lower die chamber 301, and the telescopic end of the pusher cylinder 307 is fixedly provided below the support plate 305. A guide rod 2 fixed on the extrusion device body 1 is passed through the interior of the lifting plate 5.

[0029] By adopting the above technical solution, the rubber raw material is placed in the lower mold chamber 301. The extrusion hydraulic cylinder 7 pushes the lifting plate 5 to move downward. The lifting plate 5 slides on the guide support rod 2 and gradually approaches the lower mold chamber 301, so that the upper mold 6 and the lower mold chamber 301 are pressurized. Both the upper mold 6 and the lower mold chamber 301 are equipped with heating wires, which heat the rubber at the same time to achieve hot pressing. When demolding is required, the pusher cylinder 307 pushes the support plate 305 to move upward. At this time, the lower mold chamber 301 rotates inside the extrusion device body 1 through the rotating plate 304. The lower mold chamber 301 is in an inclined state. At this time, the rubber shock-absorbing pad on the lower mold chamber 301 can slide down into the cooling water tank 405 under the action of gravity. While cooling the rubber shock-absorbing pad, the temperature of the upper mold 6 and the lower mold chamber 301 will not be excessively reduced.

[0030] Specifically, such as Figure 2 As shown, a fixed seat 306 is provided on one side of the pusher cylinder 307, and the fixed seat 306 is fixed inside the body 1 of the extrusion device. The support plate 305 is movably connected to the fixed seat 306. The top of the lower die chamber 301 is provided with several equidistantly distributed storage grooves 308, and a top material column 309 is slidably arranged inside the storage groove 308. A top material plate 310 is fixedly arranged at the bottom of the top material column 309, and several equidistantly distributed extrusion springs 311 are provided at the bottom of the top material plate 310. An extrusion telescopic rod 312 passes through the inside of the extrusion spring 311. Guide sliders 303 are provided on both the front and rear sides of the top material plate 310, and guide grooves 302 are provided at the connection between the guide sliders 303 and the lower die chamber 301.

[0031] By adopting the above technical solution, the rubber raw material is placed inside the storage groove 308 of the lower mold chamber 301. When the upper mold 6 moves downward, the rubber raw material enters the lower mold cavity formed by the storage groove 308 and the ejector pin 309 under the squeezing action of the upper mold 6, and pushes the extrusion spring 311 and the extrusion telescopic rod 312 downward to squeeze inward. After the hot pressing time is reached, the upper mold 6 moves upward, the extrusion spring 311 loses external force, and under the elastic force of the extrusion spring 311, it pushes the ejector plate 310 upward, thereby causing the ejector pin 309 to move upward, pushing the rubber shock-absorbing pad upward, and realizing the demolding of the rubber shock-absorbing pad.

[0032] Specifically, such as Figure 4 As shown, a liftable filter basket 402 is installed inside the cooling water tank 405, and a support spring 404 is provided between the filter basket 402 and the cooling water tank 405. A guide telescopic rod 407 is passed through the inside of the support spring 404. Iron blocks 403 are fixedly installed at the four bottom corners of the filter basket 402, and electromagnets 406 are fixedly installed at the four bottom corners of the cooling water tank 405. A fan 401 is installed above the cooling water tank 405.

[0033] By adopting the above technical solution, after the rubber shock-absorbing pad that fell into the cooling water tank 405 cools down, the electromagnet 406 is de-energized. At this time, the attraction between the electromagnet 406 and the iron block 403 disappears, and the support spring 404 pushes the filter basket 402 to move upward. This causes the filter basket 402 to move the rubber shock-absorbing pad located inside the filter basket 402 upward. The water level in the cooling water tank 405 is less than the length of the support spring 404. When the support spring 404 pushes the filter basket 402 upward, the rubber shock-absorbing pad can leave the water surface. This allows the rotating fan 401 to dry the rubber shock-absorbing pads inside the filter basket 402. At the same time, a drain outlet can be opened on one side of one of the iron blocks 403. A water-blocking rubber rod adapted to the drain outlet is set at the corresponding position of the filter basket 402. When the electromagnet 406 is attracted to the iron block 403, the water-blocking rubber rod is inserted into the drain outlet; otherwise, the water-blocking rubber rod is removed from the drain outlet, which facilitates the drainage of water in the cooling water tank 405. A matching water inlet pipe can also be set inside the cooling water tank 405 to introduce external water source into the cooling water tank 405.

[0034] Working principle: the rubber raw material is placed in the storage tank 308 of the lower mold bin 301, when the upper mold 6 moves downward, the rubber raw material enters the lower mold cavity formed by the storage tank 308 and the material pushing column 309 under the extrusion of the upper mold 6, and pushes the extrusion spring 311 and the extrusion telescopic rod 312 inwardly, after the hot pressing time, the upper mold 6 moves upward, the extrusion spring 311 loses external force, and pushes the material pushing plate 310 upward under the elastic force of the extrusion spring 311, so that the material pushing column 309 moves upward, pushes the rubber shock pad upward, realizes the demolding work of the rubber shock pad, at this time the rubber shock pad is located at the top of the lower mold bin 301, the extrusion hydraulic cylinder 7 is started to push the lifting plate 5 to move downward, the lifting plate 5 slides on the guide support 2, gradually approaches the lower mold bin 301, so that the upper mold 6 and the lower mold bin 301 are pressurized, the upper mold 6 and the lower mold bin 301 are provided with electric heating wires, and are heated at the same time, realizing the hot pressing work of the rubber, when demolding is needed, the material pushing cylinder 307 pushes the supporting plate 305 to move upward, at this time the lower mold bin 301 rotates in the inside of the extrusion device main body 1 through the rotating plate 304, the lower mold bin 301 is in an inclined state, at this time the rubber shock pad on the lower mold bin 301 can slide to the cooling water tank 405 under the action of gravity, cooling the rubber shock pad, and at the same time, the temperature of the upper mold 6 and the lower mold bin 301 is not excessively reduced.

[0035] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
