By providing the second limiting gear 2120 and the clamping plate 2115, the second limiting gear 2120 can drive the rotating shaft 2121 to rotate, thereby determining the extension length of the connecting rope 2118, and the clamping plate 2115 can limit the second limiting gear 2120 by utilizing the meshing relationship between the clamping plate 2115 and the second limiting gear 2120 to prevent it from rotating; See also Figure 4 The inner wall of one of the first annular frames 1 is rotatably connected with two groups of short shafts 2117, each group of short shafts 2117 has two short shafts, and the top of each short shaft 2117 is fixedly connected with a limiting plate 2116. By providing the short shafts 2117 and the limiting plates 2116, the limiting plates 2116 can be used to limit the card plate 2115 to prevent the card plate 2115 from moving upward.

[0024] The specific implementation of this embodiment is as follows: when the device is needed to be used, it is necessary to understand that when installing the lower mold core, the two first annular frames 1 and the two second annular frames 2106 need to be completely disassembled, and then the clamping plate 2131 can be pulled out from the inside of the two clamping frames 2130. At this time, the clamping plate 2131 will not contact the limit block 2128, so the limit block 2128 and the second T-shaped slider 2132 can be pushed to slide along the second T-shaped slide groove 2133 until the limit block 2128 is no longer in contact with the first limit gear 2112. At this time, the first limit gear 2112 can be manually rotated, and the first limit gear 2112 will transmit the rotational power received to the first gear through the transmission shaft 2127 when rotating. On the wheel 2126 and the second gear 2136, when the first gear 2126 rotates, it will cooperate with the meshing relationship with the first extrusion block 2125 to push the two first extrusion blocks 2125 to move, and the moving directions of the two first extrusion blocks 2125 are opposite, until the first extrusion blocks 2125 completely enter the interior of the sliding frame 2110, ensuring that the first extrusion blocks 2125 will not contact the first annular frame 1 and the second annular frame 2106. At this time, the sliding frame 2110 can be free and automatic. Here, the two sliding frames 2110 can be pushed to move together with a sliding frame 2102, so that the sliding frame 2102 is just below the lower mold core connecting hole. At this time, although the sliding frame 2102 is below the lower mold core connecting hole, However, the first sliding block 2109 is not yet directly below the connecting hole, so the positions of the first sliding block 2109 and the second sliding block 2101 need to be adjusted. Since the second gear 2136 will rotate following the rotation of the transmission shaft 2127, the second gear 2136 can also utilize the meshing relationship between the second extrusion block 2135 and the second extrusion block 2135 to push the two second extrusion blocks 2135 to move upward and downward respectively. In the process of the second extrusion block 2135 moving, the second extrusion block 2135 will push the two transmission blocks 2137 to gradually move away under the action of the first roller 2142, and when the transmission block 2137 moves away, it will also drive the two moving plates 2139 and the two moving pads 2140 to gradually move away until the moving pads 2140 are no longer aligned with the first sliding block 2109. 9, at this time, the first sliding block 2109 can move freely. When the first sliding block 2109 moves to the position just below the connecting hole of the lower mold core, the first limiting gear 2112 can be rotated in the reverse direction to reset, so that the moving pad 2140 can contact the first sliding block 2109 again. In the process of the reverse rotation of the first limiting gear 2112, the first extrusion block 2125 will also move to the top and bottom of the sliding frame 2110 until one of the first extrusion blocks 2125 inside the sliding frame 2110 contacts the first annular frame 1, and the contact surfaces of the first extrusion block 2125 and the first annular frame 1 are both made of rubber. In addition, the moving pad 2140 is also made of rubber. The large friction coefficient of rubber itself can be used to increase the stability of the sliding frame 2110 and the first sliding block 2109.When the holes are connected, the second annular frame 2106 can be installed on the surface of the first annular frame 1 by means of bolts 2107. At this time, the upper surface of another first extrusion block 2125 inside each sliding frame 2110 will contact the bottom surface of the second annular frame 2106. Then, the connection hole below the lower mold core is aligned with the self-locking shaft 2201 fixed on the inner wall of the first sliding block 2109 and moved downward. In the process of moving downward, the lower mold core will squeeze the lifting shaft 2141 to move downward, and finally the extrusion pad 2124 will contact the surface of the sliding frame 2102, further increasing the stability of the first sliding block 2109.

Each threaded shaft 2209 The outer surface of each second sliding block 2101 is threadedly connected to the inner wall of the filling block 2212, the outer surface of each threaded shaft 2209 is fixedly connected to the third gear 2208, the end of each threaded shaft 2209 away from the self-locking shaft 2201 is fixedly connected to the rotating plate 2203, the inner wall of each second sliding block 2101 is rotatably connected to the rotating cylinder 2206, the outer surface of each rotating cylinder 2206 is slidably connected to the fourth gear 2207, the outer surface of each fourth gear 2207 is meshed with the outer surface of the third gear 2208, and the inner wall of each fourth gear 2207 is rotatably connected to the third gear 2208. A fixed ring 2202, the outer surface of each fixed ring 2202 is fixedly connected with a rectangular plate 2204, and a rectangular groove 2205 is provided on a side surface close to each other of each group of second sliding blocks 2101, and the outer surface of each rectangular plate 2204 is slidably connected to the inside of the rectangular groove 2205. By setting a self-locking unit 22, the mold core and the first annular frame 1 can be connected by utilizing the self-locking unit 22, and the self-locking unit 22 cooperates with the hole position adjustment unit 21 to ensure that the connection hole positions on the first annular frame 1 can correspond to different mold core connection hole positions, and the manual locking step is eliminated.

[0027] The specific implementation of this embodiment is as follows: when the lower mold core moves downward, it pushes the lifting shaft 2141 to move downward, and a plurality of spiral strips are fixed on the surface of the lower half of the lifting shaft 2141, and a plurality of spiral grooves are also provided on the inner wall of the rotating cylinder 2206 on which the inner wall of the second sliding block 2101 rotates. As the lifting shaft 2141 continues to descend, the lifting shaft 2141 will enter the interior of the rotating cylinder 2206, and the lifting shaft 2141 cannot rotate. Therefore, as the lifting shaft 2141 continues to descend, the spiral grooves provided on the inner wall of the rotating cylinder 2206 will The filling shaft 2210 is rotated along the spiral strip, thereby transmitting power to the third gear 2208 through the fourth gear 2207 until it is transmitted to the threaded shaft 2209, so that the threaded shaft 2209 rotates, and the outer surface of the threaded shaft 2209 and the filling shaft 2210 are in a threaded connection relationship, so that the filling shaft 2210 can be pushed to move upward. In addition, the two limiting shafts 2211 fixed on the outer surface of the filling shaft 2210 slide inside the self-locking shaft 2201, so that under the limit of the limiting shaft 2211, it can be ensured that the filling shaft 2210 can only move forward. The fourth gear 2207 can be moved upward by pushing the rectangular plate 2204 to move upward, so that the fourth gear 2207 is disengaged from the third gear 2208. It should be understood that the fourth gear 2207 is not fixed to the outer surface of the rotating cylinder 2206, but is used to lock the lower mold core. The four raised cylindrical bars fixed on the surface limit the fourth gear 2207, so the fourth gear 2207 can slide on the rotating cylinder 2206. At this time, the third gear 2208 and the threaded shaft 2209 are not restricted. Therefore, the rotating plate 2203 can drive the threaded shaft 2209 to rotate, thereby driving the threaded shaft 2209 to rotate in the opposite direction, so that the four filling blocks 2212 are no longer squeezed by the filling shaft 2210, thereby achieving the purpose of disassembly, and the surface of each filling block 2212 in contact with the lower mold core is also made of rubber.

[0028] Example 3: Please refer to Figure 6 and Figure 7 The present invention provides a technical solution: a mold frame for an adjustable mold. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The limiting mechanism 3 cooperates with the adjusting mechanism 2, and the limiting mechanism 3 can provide support force to the mold core from all sides of the mold core.

[0029] As a further limitation of the limiting mechanism 3 of the present invention, the limiting mechanism 3 includes two water inlet pipes 310, the outer surface of each water inlet pipe 310 is fixedly connected to the inner wall of the second annular frame 2106, the inner wall of each second annular frame 2106 is fixedly connected with two groups of limiting frames 302, the outer surfaces of the two water inlet pipes 310 are fixedly connected to the inner walls of two of the limiting frames 302, the inner wall of each limiting frame 302 is provided with two rectangular slide grooves 306, the interior of each rectangular slide groove 306 is slidably connected with a rectangular slider 309, the side of each group of rectangular sliders 309 close to each other is fixedly connected with a transmission plate 307, and the side of each transmission plate 307 close to the second annular frame 2106 is A sealing pad 308 is fixedly connected, and a rubber pad 304 is fixedly connected to a side of each transmission plate 307 away from the sealing pad 308. The outer surfaces of each two groups of limit frames 302 are commonly fixedly connected with two groups of water pipes 305. The number of each group of water pipes 305 and each group of limit frames 302 is two. The outer surface of each water inlet pipe 310 is threadedly connected with a threaded cap 301. By setting a limiting mechanism 3, the position of the four surfaces of the mold core can be limited by the limiting mechanism 3. By setting the mutual cooperation between the hole adjustment unit 21, the self-locking unit 22 and the limiting mechanism 3, the problem of low applicability caused by the inability to adjust the installation hole position during the use of the mold frame is effectively avoided. See also Figure 6 A heat dissipation pipe 303 is provided inside each second annular frame 2106, and the outer surface of each heat dissipation pipe 303 is fixedly connected to the inner wall of the second annular frame 2106. By providing the heat dissipation pipe 303, the heat dissipation pipe 303 can be used to guide cold water into the interior of the second annular frame 2106 to dissipate the heat of the mold core when it is working.

[0030] The specific implementation of this embodiment is as follows: after the lower mold core is locked, the threaded cap 301 can be unscrewed, and then liquid is transported to the interior of the limit frame 302 through the water inlet pipe 310. The water entering the limit frame 302 will be evenly distributed in the other three limit frames 302 through the water guide pipe 305. As the liquid continues to enter, the liquid will squeeze the transmission plate 307 inside the limit frame 302 to move to the position of the lower mold core until the rubber pad 304 fixed on one side of the transmission plate 307 contacts one side of the lower mold core. Since the lower mold core has been limited in position by the self-locking unit 22, this limit frame There will be no more space inside 302 to accommodate the liquid, and the liquid will flow to the other three limit frames 302 that have not yet limited the lower mold core, until the transmission plates 307 and rubber pads 304 in the four limit frames 302 have completed the position limitation of the lower mold core, and then the liquid delivery can be stopped. In this way, the position of the lower mold core can be limited in four directions to make it more stable. Then repeat the above operation to install and fix the upper mold core, and then lift the two first annular frames 1 and the second annular frames 2106 connected to the upper mold core to the top of the lower mold core, and cooperate with the positioning shaft 2113 and the positioning cylinder 2104 to align the two mold cores.
