Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a double-station cover plate forming mold. Background Art

[0002] A dual-station cover forming mold is a mold used to produce cover panels that features two working stations. This means the mold can accommodate the production of two cover panels simultaneously, increasing production efficiency within the same timeframe. Typically, this mold is designed to produce one cover panel in one station while the other panel is being produced in the other station. This allows the operator to produce both cover panels in a single cycle, reducing manufacturing time and costs.

[0003] A search revealed a Chinese patent with publication number CN214239333U, which discloses a mold for forming a charging pile upper cover. The patent describes a simple, convenient, and highly practical technical solution that employs an ejection mechanism and a first drive mechanism. The method injects compressed gas into the high-pressure air intake pipe, converts it into hot gas through a vortex tube, and then enters the drive box, causing the slide to move upward, thereby driving the ejector plate upward and ejecting the formed lithium battery cover plate from the lower mold. This facilitates removal of the formed lithium battery cover plate.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] Embodiment 1: A double-station cover forming mold, including a workbench 1, a fixed plate 2 is fixedly connected to one side of the workbench 1, a motor 3 is fixedly connected to the top of the fixed plate 2, and a vertical plate 4 is fixedly connected to the top of the workbench 1, a positioning mechanism is provided between the vertical plate 4 and the workbench 1, and the positioning mechanism includes two pairs of L-shaped connecting frames 10 and two pairs of clamping plates 17, a pair of fixed plates 2 5 are fixedly connected to both sides of the vertical plate 4, and a bidirectional threaded rod 7 is rotatably connected between the fixed plates 2 5 on both sides, one end of the bidirectional threaded rod 7 on one side is fixedly connected to the output end of the motor 3, one end of the bidirectional threaded rod 7 on one side is fixedly connected to a pulley 1 6 on the outer wall, and the other end of the bidirectional threaded rod 7 on the outer wall is fixedly connected to a pulley 2 8, and the pulley 1 6 and the pulley 2 8 are connected by a belt 9, L-shaped connection The frame 10 is threadedly connected to the outer walls of the two-way threaded rods 7 on both sides. A pair of connecting blocks 13 are fixedly connected to one side of the L-shaped connecting frame 10. At the same time, sliding grooves 16 are opened inside both sides of the vertical plate 4, and the connecting blocks 13 correspond to the sliding grooves 16. At the same time, the connecting blocks 13 are slidably connected in the sliding grooves 16. At the same time, the inner wall of the L-shaped connecting frame 10 is fixedly connected to the telescopic rod 11, and the outer wall of the telescopic rod 11 is provided with a spring 12. At the same time, a splint 17 is fixedly connected to the other end of the telescopic rod 11 and the spring 12, and a soft pad 18 is fixedly connected to the inside of the splint 17. The other end of the L-shaped connecting frame 10 is fixedly connected to the positioning plate 15. At the same time, both ends of the workbench 1 are fixedly connected to the positioning rod 14, and the positioning plate 15 is slidably connected to the outer wall of the positioning rod 14. A lower mold 19 is provided between the L-shaped connecting frames 10 on both sides.

[0026] After placing the lower mold 19 between a pair of L-shaped connecting frames 10 on either side, the motor 3 on the fixed plate 1 is activated. This drives the bidirectional threaded rod 7 to rotate, which in turn drives the pulley 1 6 to rotate. This, in turn, drives the pulley 2 8 on the other side and the internal bidirectional threaded rod 7 to rotate via the belt 9. As the bidirectional threaded rod 7 rotates, the L-shaped connecting frames 10 at both ends move in opposite directions, and the clamping plates 17 move accordingly to clamp and secure the lower mold 19. The clamping plates 17 are equipped with cushions 18 to prevent slippage, and the retractability of the telescopic rod 11 and the elasticity of the spring 12 are used to minimize damage to the lower mold 19. Simultaneously, the L-shaped connecting frame 10 is restrained within the slide slot 16 and on the positioning rod 14 by the connecting block 13 and the positioning plate 15 during movement, preventing it from shifting. These coordinated operations allow for the rapid replacement and positioning of the lower mold 19, thereby improving work efficiency.

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 is that, a bracket 21 is connected to the top of the workbench 1, a pair of electric hydraulic rods 22 are fixedly connected to the top of the bracket 21, and the output end of the electric hydraulic rod 22 is fixedly connected to the base plate 23, an upper mold 24 is provided at the bottom of the base plate 23, and a connecting mechanism is provided between the upper mold 24 and the base plate 23, the connecting mechanism includes a fixed column 1 26 and a fixed column 2 27, limiting rods 25 are fixedly connected to both sides of the top of the base plate 23, and the limiting rods 25 pass through the bracket 21 and extend to the top of the base plate 23, the fixed column 1 26 is fixedly connected to the upper mold 24, and the fixed column 2 27 is fixedly connected to the base plate 23, and a groove 20 of the same size is opened on the same side of the fixed column 1 26 and the fixed column 2 27, and a pin 28 is provided between the fixed column 1 26 and the fixed column 2 27, and the pin 28 is slidably connected in the groove 20.

[0028] Insert the fixing column 1 26 of the upper mold 24 into the base plate 23, and align its groove 20 with the groove 20 of the fixing column 27 on the base plate 23. Then insert the pin 28 into the groove 20 to install the upper mold 24 on the base plate 23. By starting the electric hydraulic rod 22 on the bracket 21, the upper mold 24 on the base plate 23 moves downward. At the same time, the base plate 23 limits the moving direction through the limit rod 25 when moving downward. After the injection molded part is poured into the lower mold 19, the upper mold 24 moves down to the inside of the lower mold 19 and starts plasticization. When the upper mold 24 needs to be replaced, it only needs to pull out the pin 28 to remove the upper mold 24, which realizes quick installation and disassembly, greatly improving work efficiency.

[0029] During operation, when the staff produces the cover plate, they first place the lower mold 19 between a pair of L-shaped connecting frames 10 on both sides, and then start the motor 3 on the fixed plate 12. Under the action of the motor 3, the bidirectional threaded rod 7 is driven to rotate. At the same time, when the bidirectional threaded rod 7 rotates, it will drive the pulley 16 to rotate, and drive the pulley 2 8 on the other side and the internal bidirectional threaded rod 7 to rotate through the belt 9. When the bidirectional threaded rod 7 rotates, it drives the L-shaped connecting frames 10 at both ends to move in the opposite direction. At the same time, the L-shaped connecting frame 10 moves inward to drive the splint 17 to move and clamp the lower mold 19. While fixing, the soft pad 18 on the splint 17 is used to prevent slipping. When the splint 17 is clamped, the elasticity of the telescopic rod 11 and the elasticity of the spring 12 are used to reduce the damage caused by the splint 17 directly clamping the lower mold 19. At the same time, when the L-shaped connecting frame 10 moves, it is limited in the slide groove 16 and on the positioning rod 14 by the connecting block 13 and the positioning plate 15 to prevent When the upper mold 24 is moved downward, the upper mold 24 is moved downward to the inside of the lower mold 19 and plastic molding is started. When the upper mold 24 needs to be replaced, the latch 28 is directly pulled out, and the upper mold 24 can be directly removed and replaced, thereby achieving the effect of quick installation and disassembly, which greatly improves work efficiency.
