[0001] This utility model relates to the field of rolling mill production technology, specifically to a metal mold casting device for rolling mill production. Background Technology

[0002] The main working parts and tools on a rolling mill that cause continuous plastic deformation of metal are rolls. Rolls are mainly composed of three parts: roll body, roll neck, and shaft end. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing and transmits the rolling force to the stand through the bearing seat and the pressing device. The shaft end of the transmission end is connected to the gear seat through the connecting shaft and transmits the rotational torque of the motor to the roll. Rolls can be arranged in two-roll, three-roll, four-roll, or multi-roll configurations in the rolling mill stand. Rolls need to be cast using a metal mold casting device during the production process.

[0003] Existing metal mold casting equipment typically consists of two sets of molds that can be spliced ​​together. The molds have detachable shaping columns inside. Molten metal is poured into the molds to complete the shaping process. The upper and lower molds of the metal mold casting equipment usually need to be fixed with bolts. The bolts need to be removed or installed during demolding or use. During repeated removal and installation, the bolts may strip, affecting the production efficiency of the rolls. Utility Model Content

[0028] 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.

[0029] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0030] Please see Figure 1-5The upper mold 1, lower mold 2, and fixing part 3 are provided. The outer wall of the upper mold 1 is provided with a connecting ring, and the bottom of the connecting ring has a fixing groove. The lower mold 2 is located below the upper mold 1. The lower mold 2 has a detachable cylinder inside, which is used to shape the roll. The fixing part 3 is located below the lower mold 2 and has fixing frames 301 fixed to both sides of the bottom of the lower mold 2. The fixing frames 301 are fixed to the bottom of the lower mold 2 by welding, improving the stability of the overall structure. The fixing frames 301 have internal... The transmission plate 302 is made of stainless steel to prevent rusting during prolonged use. A connecting rod 303 is hinged to the top of the transmission plate 302. Vertical movement of the transmission plate 302 drives the connecting rod 303 to rotate. A fixing plate 304 is hinged to the top of the connecting rod 303. Rotation of the connecting rod 303 drives the fixing plate 304 to move horizontally. The fixing plate 304 is embedded in the fixing groove of the connecting ring, thus fixing the upper mold 1. A spring 306 is fixedly installed at the bottom of plate 302. The spring 306 is in a stretched deformation state, and its bottom end is connected to the inner wall of the fixed frame 301. The spring 306 can drive the transmission plate 302 to return to its initial position. Sliding rods 305 are fixedly installed on both sides inside the fixed frame 301, and the sliding rods 305 are slidably connected to the fixed plate 304. The sliding rods 305 limit the fixed plate 304 to ensure the stability of the fixed plate 304 during horizontal movement. A limiting rod is fixedly installed at the bottom of the inner side of the fixed frame 301. The positioning rod 307 is slidably connected to the transmission plate 302. The positioning rod 307 limits the transmission plate 302 to ensure the stability of the transmission plate 302 during vertical movement. The top of the fixing plate 304 is sloping, and the inner side of the fixing groove of the upper mold 1 is also sloping. A sealing gasket is provided above the lower mold 2. As the fixing plate 304 moves gradually, it will gradually drive the upper mold 1 to move downward under the influence of the sloping surface, thereby compressing the sealing gasket and ensuring the sealing between the upper mold 1 and the lower mold 2.

[0031] Please see Figure 1-5Support part 4 is located below the lower mold 2. Support part 4 has a support plate 401 fixed to the bottom of the fixed frame 301. The support plate 401 is made of stainless steel to prevent rusting during prolonged use. A rotating block 402 is fixed above the support plate 401 and is connected to the support plate 401 by bolts, facilitating replacement of damaged rotating blocks 402. A threaded rod 403 is rotatably connected to the rotating block 402. A push block 404 is rotatably connected to one end of the threaded rod 403 located below the transmission plate 302. Rotation of the threaded rod 403 can drive the push block 404 forward. The push block 404 moves horizontally and is in contact with the bottom of the transmission plate 302. The movement of the push block 404 can drive the transmission plate 302 to move. A sliding protrusion 405 is fixed on the top of the support plate 401 and is slidably connected to the push block 404. The sliding protrusion 405 limits the push block 404 and ensures the stability of the sliding protrusion 405 during movement. The top of the push block 404 has a smooth inclined surface, and the bottom of the transmission plate 302 has a smooth inclined surface. The inclined surface of the push block 404 is in contact with the inclined surface of the transmission plate 302. The movement of the push block 404 can more stably push the transmission plate 302 upward.

[0032] Working principle: First, when the mold needs to be disassembled, manually rotate the threaded rod 403. The rotation of the threaded rod 403 will gradually move away from the rotating block 402 under the influence of the thread. Since the threaded rod 403 is rotatably connected to the push block 404 and the push block 404 is slidably connected to the push block 404, the movement of the threaded rod 403 will drive the push block 404 to move. The push block 404 gradually separates from the transmission plate 302. During the process of the push block 404 separating from the transmission plate 302, the spring 306 will gradually restore its deformation and pull the transmission plate 302 downward.

[0033] Then, since the transmission plate 302 is hinged to the connecting rod 303, and the connecting rod 303 is hinged to the fixed plate 304, and the fixed plate 304 is slidably connected to the sliding rod 305, the downward movement of the transmission plate 302 will drive the fixed plate 304 to move towards the upper mold 1 side under the influence of the connecting rod 303. The fixed plate 304 gradually separates from the fixed groove of the upper mold 1, thereby releasing the fixation between the upper mold 1 and the lower mold 2. Then, the upper mold 1 can be pulled upward to complete the disassembly. Subsequently, the rollers inside the lower mold 2 can be demolded.

[0034] Finally, when it is necessary to assemble the molds, place the upper mold 1 on top of the lower mold 2, and align the bottom fixing groove of the upper mold 1 with the protrusion above the fixing plate 304. Then, rotate the threaded rod 403 in the opposite direction. The rotation of the threaded rod 403 drives the push block 404 to move and fit against the transmission plate 302. The movement of the push block 404 will push the transmission plate 302 to move upward. The upward movement of the transmission plate 302 will drive the fixing plate 304 to move under the action of the connecting rod 303. The movement of the fixing plate 304 will gradually insert into the fixing groove of the upper mold 1 to complete the fixing.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
