[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides Figure 1-6 The rubber vulcanization molding machine shown includes a base 1 and further includes:

[0026] The hydraulic assembly further includes a hydraulic platform 2 and a hydraulic rod 201. The hydraulic rod 201 is slidably connected to the middle of the top of the hydraulic platform 2. A plurality of sliding rods 104 are provided on the top edge of the hydraulic platform 2. A sliding platform 204 is provided on the top of the hydraulic rod 201.

[0027] The vulcanization assembly further includes a heating platform 205, a lower pressing plate 202 and an upper pressing plate 203, wherein the lower pressing plate 202 is arranged on the top of the sliding platform 204;

[0028] A replaceable pressing platform 3 is provided at the top of the lower pressing plate 202. A slide rail 302 is provided on the inner wall of the lower pressing plate 202. A threaded rack 402 is provided on the top of the sliding platform 204. A plurality of threaded rods 4 are threadedly connected to the inner wall of the threaded rack 402.

[0029] It should be noted that the hydraulic table 2 and the hydraulic rod 201 refer to the hydraulic part of the flat vulcanizing press with model number 250T. Under the action of the hydraulic table 2, the hydraulic rod 201 can push the sliding table 204 upward to slide upward along the sliding rod 104. The lower pressure plate 202 and the upper pressure plate 203 refer to the clamping part of the model 250T. The sliding table 204 pushes the lower pressure plate 202 to clamp the rubber raw material between the lower pressure plate 202 and the upper pressure plate 203. By heating, the rubber raw material is vulcanized and formed. The replaceable pressure table 3 can be replaced with a more vulcanized shape. The replaceable pressure table 3 can be released by rotating the threaded rod 4 to cooperate with the threaded frame 402 to replace the new replaceable pressure table 3.

[0030] Specifically, a top cover 105 is provided at the top of the heating platform 205, a sliding rod 104 passes through the sliding platform 204 and is fixedly connected to the bottom end of the top cover 105, an upper pressure plate 203 is provided at the bottom end of the heating platform 205, a first base 101 is provided at the top of the base 1, a hydraulic platform 2 is provided at the top of the first base 101, and a second base 102 is provided at the top of the first base 101 and at the end away from the first base 101.

[0031] It should be noted that the heating platform 205 is based on the heating structure of a 250T flat plate vulcanizer, and its operating principle is the same as that of the device of this model. The upper pressing plate 203 is set at the bottom end of the heating platform 205. When the rubber raw material is clamped between the lower pressing plate 202 and the upper pressing plate 203, the heating of the heating platform 205 can make the rubber raw material reach the temperature required for vulcanization.

[0032] Specifically, a connecting plate 403 is provided at one end of the threaded rod 4 close to the slide rail 302, and a plurality of slide bars 303 are symmetrically provided at one end of the connecting plate 403 away from the threaded rod 4. The outer walls of the plurality of slide bars 303 are slidably connected to the inner wall of the slide rail 302, and a handle 401 is provided at one end of the threaded rod 4 away from the slide bar 303. A plurality of fixing grooves 304 are symmetrically provided at the top of the lower pressure plate 202 and at one end close to the slide rail 302. A plurality of fixing protrusions 301 are symmetrically provided on both sides of the replaceable pressing platform 3, and the bottom ends of the plurality of fixing protrusions 301 are inserted through the slide rail 302 and the inner wall of the fixing groove 304.

[0033] It should be noted that the fixing groove 304 is set at the top of the lower pressure plate 202, and the groove of the fixing groove 304 cuts off the middle end of the slide rail 302. The shape of the fixing protrusion 301 is a "concave" block. When the "concave" block is set on the inner wall of the fixing groove 304, its "concave" shape does not affect the normal sliding path of the slide rail 302 and the slide bar 303. One end of the connecting plate 403 is connected to the threaded rod 4, and the other end is fixed with multiple slide bars 303. Then, the threaded rod 4 is rotated to make the threaded rod 4 cooperates with the threaded frame 402, so that the threaded rod 4 pushes the connecting plate 403 to move horizontally toward the slide rail 302. At the same time, the connecting plate 403 pushes the slide bar 303 to slide in the slide rail 302. The slide bar 303 slides through the cut-off position, so that a closed space is formed between the slide bar 303 and the fixing groove 304 to block and fix the fixed protrusion 301. The fixed protrusion 301 can be blocked and unlocked by rotating the threaded rod 4 to slide the slide bar 303, thereby achieving the purpose of replacing the replaceable press table 3.

[0034] Specifically, an operating box 103 is provided on one side of the top cover 105 close to the second base 102, a start button 107 is provided at the front end of the operating box 103, a motor 106 is provided at the top of the second base 102, and a pull rod 305 is provided at the top of the second base 102 and at one end close to the motor 106.

[0035] It should be noted that the operating box 103 and the start button 107 refer to the operating components of a flat-plate vulcanizer with a model of 250T. The front end of the operating box 103 is also provided with an interface for displaying parameters and a button for starting the operating heating platform 205. The pull rod 305 refers to the movable rod of a flat-plate vulcanizer with a model of 250T. The pull rod 305 connects the motor 106, the operating box 103 and the hydraulic platform 2. By pulling the pull rod 305, the pressure of the hydraulic rod 201 can be released to stop the motor 106 from working.

[0036] Working principle of this utility model:

[0037] The specific operation is that the operator needs to put the rubber semi-finished product on the top of the replaceable press table 3, and then press the start button 107 to make the motor 106 run, and then the hydraulic rod 201 of the hydraulic table 2 will push the sliding table 204, and at the same time the sliding table 204 will climb upward along the sliding rod 104, and the sliding rod 104 will drive the replaceable press table 3 together with the rubber semi-finished product to be squeezed toward the heating table 205, and finally squeeze the rubber semi-finished product between the heating table 205 and the replaceable press table 3. The rubber semi-finished product is vulcanized and shaped under extrusion and heating, and the pull rod 305 is pulled down to release the pressure of the hydraulic table 2 to make the sliding table 2 04 drops down and takes out the finished product. The shape of the finished product can be changed by replacing the replaceable pressing platform 3. The threaded rod 4 needs to be rotated. The threaded rod 4 is threadedly matched with the threaded frame 402 to enable the threaded rod 4 to push the connecting plate 403. Then the connecting plate 403 pushes the slide 303 to slide in the slide rail 302. During the sliding process, the slide 303 will pass through the fixed groove 304 and lock the movement direction of the fixed protrusion 301, so that the fixed protrusion 301 is fixed in the fixed groove 304. If the threaded rod 4 is rotated to drive the slide 303 to slide out of the fixed groove 304, the lock on the replaceable pressing platform 3 can be released, and the replaceable pressing platform 3 can be replaced.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
