DETAILED DESCRIPTION

[0021] See also Figure 1-5 The utility model provides an upper mold locking and clamping mechanism of a large mold frame, comprising a lower mold frame 1 and an upper mold frame 2. The upper mold frame 2 is arranged on the top of the lower mold frame 1. Two fixing seats 7 are fixed on one side of the lower mold frame 1 and the other side of the upper mold frame 2. Two connecting seats 8 are fixed on the other side of the lower mold frame 1 and one side of the upper mold frame 2. A slot 10 is fixed on one side of the fixing seat 7. An insert rod 9 is provided on the surface of the fixing seat 7. One side of the slot 10 extends to the inside of the insert rod 9 at an adjacent position. The upper and lower ends of the inner cavity of the insert rod 9 are provided with inner grooves 11 which are symmetrically distributed. A movable block 12 is fixed inside the inner groove 11. One end of the movable block 12 is fixed There is a spring 13, one end of the spring 13 is fixed to one end of the inner wall of the inner groove 11 at the adjacent position, and fixed grooves 16 are provided at the upper and lower ends of the outer circumferential surface of the slot 10. One end of the movable block 12 extends to the inside of the fixed groove 16 at the adjacent position, and a limiting block 18 is fixed to one end of the inner cavity surface of the fixed groove 16. A reinforcement groove 17 is provided on the surface of one end of the movable block 12, and one end of the limiting block 18 extends to the inside of the reinforcement groove 17 at the adjacent position, and slides from the top side of the lower mold frame 1 to the top of the lower mold frame 1 through the upper mold frame 2, thereby limiting the slot 10, so that the lower mold frame 1 and the upper mold frame 2 can be installed and connected.

[0022] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that two fixing blocks 3 are fixed on both sides of the top surface of the lower mold frame 1, openings 4 are penetrated through the surfaces of both sides of the bottom of the upper mold frame 2, connecting strips 5 are fixed on both ends of the top surface of the lower mold frame 1, and strip grooves 6 are opened on both ends of the bottom surface of the upper mold frame 2, and one side of the strip groove 6 is connected with the outside of the upper mold frame 2. When the upper mold frame 2 slides to the top of the lower mold frame 1, the fixing block 3 is located inside the adjacent opening 4 and the connecting strip 5 is located inside the adjacent strip groove 6, and under the interference between one side of the inner cavity surface of the strip groove 6 and the connecting strip 5, it can be ensured that the upper mold frame 2 is directly above the lower mold frame 1.

[0023] Further as Figure 5 As shown, it is worth explaining in detail that the movable block 12 is provided with abutment holes 15 at the positions on both sides of the surface of the adjacent position spring 13, and an embedded shaft 14 is inserted into the inside of the contact hole 15, and one end of the embedded shaft 14 is fixed to one end of the inner wall of the inner groove 11. Through the interference between the embedded shaft 14 and the inner cavity surface of the contact hole 15, the movement trajectory of the movable block 12 can be limited to ensure its smooth movement in the vertical direction.

[0024] Further as Figure 2 As shown, it is worth explaining in detail that a mounting plate 19 is fixed on one side surface of the lower mold frame 1 at the middle position of the two fixed seats 7, a threaded rod 20 is threadedly connected inside the mounting plate 19, and a resistance rod 21 is rotatably connected on one side of the threaded rod 20, and a limiting rod 22 is fixed on the surface of the mounting plate 19 at the bottom of the resistance rod 21, and a limiting sleeve 23 is provided on the sliding sleeve of the outer circumference of the limiting rod 22, and the top of the limiting sleeve 23 is fixed to the bottom surface of the resistance rod 21. When it is necessary to separate the lower mold frame 1 and the upper mold frame 2, the threaded rod 20 is rotated to extend through the cooperation with the threaded structure of the mounting plate 19. Since the limiting sleeve 23 can only slide horizontally along the outer circumference of the limiting rod 22, it can limit the movement trajectory of the resistance rod 21, so that the resistance rod 21 is driven by the threaded rod 20 and the surface of the upper mold frame 2 is in resistance, so that the upper mold frame 2 is separated from the lower mold frame 1.

[0025] This solution has the following working process: in actual use, when the user needs to install and combine the lower mold frame 1 and the upper mold frame 2, the upper mold frame 2 is slid from one side of the top of the lower mold frame 1 to the top of the upper mold frame 2. When the upper mold frame 2 slides to the top of the lower mold frame 1, the fixed block 3 is inside the adjacent position opening 4 and the connecting strip 5 is inside the adjacent position slot 6, and under the interference between one side of the inner cavity surface of the slot 6 and the connecting strip 5, it can ensure that the upper mold frame 2 is directly above the lower mold frame 1. During this process, one side of the slot 10 will extend to the inside of the adjacent position plug rod 9, and its outer peripheral surface will interfere with the adjacent position movable block 12, so that the movable block 12 extends toward the inside of the adjacent position inner groove 11, so that the spring 13 is deformed, so that when the fixed groove 16 moves to one end position of the movable block 12, the movable block 12 can be embedded in the fixed groove 16 under the action of the rebound force of the spring 13. At the same time, the top of the limiting block 18 can extend to the inside of the reinforcement groove 17 to further limit the movable block 12, so that the slot 10 can be limited and reinforced so that the lower mold frame 1 is fixed adjacent to the upper mold frame 2. When the lower mold frame 1 and the upper mold frame 2 need to be disassembled and separated, the threaded rod 20 is rotated to extend it through the cooperation with the threaded structure of the mounting plate 19. Since the limiting sleeve 23 can only slide horizontally along the outer circumference of the limiting rod 22, it can limit the movement trajectory of the interference rod 21. Driven by the threaded rod 20, the interference rod 21 conflicts with the surface of the upper mold frame 2, so that the upper mold frame 2 slides to one side of the lower mold frame 1, so that the fixed groove 16 conflicts with the movable block 12 in the adjacent position, so that it extends to the inside of the inner groove 11 again, so that the slot 10 can be detached from the inside of the insertion rod 9, so that the upper mold frame 2 is separated from the lower mold frame 1.

[0026] According to the above working process, it can be known that: the upper mold frame 2 slides from one side of the top of the lower mold frame 1 to the top of the lower mold frame 1, so that the interference between the fixed block 3 and the opening 4, the interference between the connecting bar 5 and the strip groove 61, and the limiting effect of the slot 10 can be used to install and connect the lower mold frame 1 and the upper mold frame 2, thereby saving installation steps, improving the convenience of use of the device and speeding up the installation, thereby improving the practicality of the device, and by rotating the threaded rod 20, the interference rod 21 can move in the horizontal direction, so that the lower mold frame 1 and the upper mold frame 2 can be separated after installation under the interference between the interference rod 21 and the upper mold frame 2, thereby facilitating the disassembly of the lower mold frame 1 and the upper mold frame 2, thereby further improving the convenience of use of the device.

[0027] Further as Figure 5As shown, it is worth explaining in detail that the diameter of the outer circumference of the limit rod 22 close to the lower mold frame 1 is larger than the diameter of the outer circumference away from the lower mold frame 1, and the diameter of the outer circumference of the limit rod 22 close to the lower mold frame 1 is larger than the hole diameter on the surface of the limit sleeve 23. Due to the shape setting of the limit rod 22, the limit sleeve 23 can be prevented from sliding from the outer circumference of the limit rod 22 under the interference between the limit sleeve 23 and the outer circumference of the limit rod 22 close to the lower mold frame 1.

[0028] In summary: by sliding the upper mold frame 2 from one side of the top of the lower mold frame 1 to just above the lower mold frame 1, the lower mold frame 1 and the upper mold frame 2 can be installed and connected by the interference between the fixed block 3 and the opening 4, the interference between the connecting bar 5 and the strip groove 61, and the limiting effect of the slot 10, thereby saving the installation steps, improving the convenience of use of the device and the fast installation speed, thereby improving the practicality of the device, and by rotating the threaded rod 20, the interference rod 21 can be moved in the horizontal direction, so that the lower mold frame 1 and the upper mold frame 2 can be easily separated after installation under the interference between the interference rod 21 and the upper mold frame 2, so as to facilitate the disassembly of the lower mold frame 1 and the upper mold frame 2, thereby further improving the convenience of use of the device, and due to the shape setting of the limit rod 22, the limit sleeve 23 can be prevented from sliding from the outer peripheral surface of the limit rod 22 under the interference between the limit sleeve 23 and the outer peripheral surface of the limit rod 22 close to the side of the lower mold frame 1.
