Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for producing plastic products with good sealing performance. Background Technology

[0002] Molds used in the production of plastic products, or simply plastic molds, are key tools in the production of plastic products. Their main function is to give plastic products a complete shape and precise dimensions.

[0003] Existing molds for producing plastic products with good sealing properties often have complex molding cavity shapes and relatively narrow internal spaces, making it difficult to remove the workpiece smoothly from the mold after the plastic has cooled and solidified. Traditional solutions often involve manual methods, such as using tools or manually tapping the mold to assist in demolding. However, this method is not only inefficient but also prone to damaging the mold and the workpiece, thereby affecting product quality and production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing sealed plastic molds used in production have complex molding cavities and narrow spaces, making it difficult to remove the plastic after it cools. The traditional method is manual demolding, but it is inefficient and easily damages the mold and workpiece, affecting quality and efficiency. Therefore, we propose a mold for producing plastic products with good sealing performance.

[0005] To achieve the above objectives, this application adopts the following technical solution: a mold for producing plastic products with good sealing performance, comprising a base, a plurality of telescopic rods installed on the top of the base, an upper mold base fixedly connected to the top of the telescopic rods, a lower mold base fixedly connected to the top of the base, a slot opened on the top of the lower mold base, a movable groove opened at one end of the base, a through hole opened at the top of the movable groove and the bottom of the slot cavity, a baffle fixedly connected inside the movable groove, an adjusting rod slidably connected inside the baffle, an arc-shaped pushing block fixedly connected to one end of the adjusting rod, an arc-shaped force-bearing block abutting at one end of the arc-shaped pushing block, a connecting rod fixedly connected to the top of the arc-shaped force-bearing block, and a top plate fixedly connected to the top of the connecting rod.

[0006] Preferably, guide grooves are provided on both sides of the inner cavity of the movable groove, and guide blocks are fixedly connected to both sides of the arc-shaped push block.

[0007] Preferably, a thrust spring is fixedly connected to the top of the arc-shaped force-bearing block, and the top of the thrust spring is fixedly connected to the top of the inner cavity of the movable groove.

[0008] Preferably, the top plate is made of high-quality alloy steel.

[0009] Preferably, one end of the baffle is fixedly connected to an extension block, the inside of the extension block is slidably connected to a plug rod, the top of the plug rod is fixedly connected to a pull block, and the top of the adjusting rod has two plug holes.

[0010] Preferably, a return spring is fixedly connected to the bottom of the pull block, and the bottom of the return spring is fixedly connected to the top of the extension block.

[0011] Preferably, the surface of the plug rod is slidably connected to the inside of the plug hole, and the outer diameter of the plug rod is adapted to the inner diameter of the plug hole.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator moves the adjusting rod, which drives the arc-shaped pushing block to move into the movable groove. The arc-shaped pushing block then pushes the arc-shaped force block to move, causing the arc-shaped force block to move the connecting rod and the top plate upward. At this point, the top plate disengages from the upper mold base, thus enabling convenient removal of the plastic product from inside the upper mold base. This not only simplifies the mold removal process but also greatly improves operational efficiency and reduces the problem of difficulty in removing the mold due to its good sealing.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 3 As shown, this utility model provides a technical solution: a mold for producing plastic products with good sealing performance, including a base 1, a plurality of telescopic rods 2 installed on the top of the base 1, an upper mold base 3 fixedly connected to the top of the telescopic rods 2, a lower mold base 4 fixedly connected to the top of the base 1, a slot 5 opened on the top of the lower mold base 4, a movable groove 6 opened at one end of the base 1, a through hole 7 opened at the top of the movable groove 6 and the bottom of the slot 5, a baffle 8 fixedly connected inside the movable groove 6, an adjusting rod 9 slidably connected inside the baffle 8, an arc-shaped pushing block 10 fixedly connected to one end of the adjusting rod 9, and one end of the arc-shaped pushing block 10... An arc-shaped force-bearing block 11 is abutted against the upper mold base 3. A connecting rod 12 is fixedly connected to the top of the arc-shaped force-bearing block 11, and a top plate 13 is fixedly connected to the top of the connecting rod 12. The operator moves the adjusting rod 9, which drives the arc-shaped pushing block 10 to move into the movable groove 6. The arc-shaped pushing block 10 pushes the arc-shaped force-bearing block 11 to move, which in turn drives the connecting rod 12 and the top plate 13 to move upward. At this time, the top plate 13 disengages from the upper mold base 3, thereby realizing the convenient removal of the plastic product inside the upper mold base 3. This not only simplifies the mold removal process but also greatly improves the operating efficiency and reduces the problem of difficulty in removing the mold due to its good sealing.

[0021] Reference Figure 3 As shown in this embodiment: guide grooves 14 are provided on both sides of the inner cavity of the movable groove 6, and guide blocks 15 are fixedly connected to both sides of the arc-shaped push block 10. By setting the guide grooves 14 and guide blocks 15, the movement of the arc-shaped push block 10 is guided and limited, which improves the stability of the arc-shaped push block 10 when it moves and avoids the phenomenon of the arc-shaped push block 10 deviating when it moves.

[0022] Reference Figure 3 As shown in this embodiment: A thrust spring 16 is fixedly connected to the top of the arc-shaped force block 11. The top of the thrust spring 16 is fixedly connected to the top of the inner cavity of the movable groove 6. By setting the thrust spring 16, when the arc-shaped force block 11 moves upward under the thrust of the arc-shaped push block 10, the thrust spring 16 is compressed. When the operator releases the adjusting rod 9, the thrust spring 16 uses its own elasticity to push the arc-shaped force block 11 back to its original position. The arc-shaped force block 11 drives the connecting rod 12 and the top plate 13 to move downward, so that the top plate 13 abuts against the upper mold base 3 again, without the need for the operator to manually reset the top plate 13.

[0023] Reference Figure 3 As shown in this embodiment, the top plate 13 is made of high-quality alloy steel. The top plate 13 is made of high-quality alloy steel, which is not only hard and wear-resistant, but also corrosion-resistant, and can maintain good stability and durability during long-term use.

[0024] Reference Figure 4 As shown in this embodiment: one end of the baffle 8 is fixedly connected to an extension block 17, the inside of the extension block 17 is slidably connected to a plug rod 18, the top of the plug rod 18 is fixedly connected to a pull block 19, and the top of the adjusting rod 9 is provided with two plug holes 20. By inserting the plug rod 18 into the plug holes 20 provided at the top of the adjusting rod 9, the position of the adjusting rod 9 is locked, preventing the adjusting rod 9 from sliding inside the baffle 8, and ensuring the stability of the adjusting rod 9 when in use or not in use.

[0025] Reference Figure 4 As shown in this embodiment: a return spring 21 is fixedly connected to the bottom of the pull block 19. The bottom of the return spring 21 is fixedly connected to the top of the extension block 17. By setting the return spring 21, when the pull block 19 moves the plug rod 18, the elastic force of the return spring 21 can be used to make the plug rod 18 automatically return to the initial position without being subjected to external force, so as to facilitate the quick locking of the position of the adjusting rod 9.

[0026] Reference Figure 4 As shown in this embodiment: the surface of the plug rod 18 is slidably connected to the inside of the plug hole 20, and the outer diameter of the plug rod 18 is adapted to the inner diameter of the plug hole 20. By setting the plug rod 18 to be slidably connected to the plug hole 20, and the outer diameter of the plug rod 18 being adapted to the inner diameter of the plug hole 20, the plug rod 18 can be stably inserted into the inside of the plug hole 20 without shaking or falling off.

[0027] Working principle: By moving the adjusting rod 9, the operator moves the arc-shaped pushing block 10 into the movable groove 6. This causes the arc-shaped pushing block 10 to push the arc-shaped force-bearing block 11, which in turn moves the connecting rod 12 and the top plate 13 upwards. At this point, the top plate 13 disengages from the upper mold base 3, allowing for easy removal of the plastic product from inside the upper mold base 3. This simplifies the mold removal process, significantly improves operational efficiency, and reduces the difficulty of mold removal due to good mold sealing. The guide groove 14 and guide block 15 guide and limit the movement of the arc-shaped pushing block 10, improving its stability and preventing deviation. The thrust spring 16 compresses when the arc-shaped force-bearing block 11 moves upwards under the thrust of the arc-shaped pushing block 10. When the operator releases the adjusting rod 9, the thrust spring 16 uses its own elasticity to push the arc-shaped force-bearing block 11 upwards. The movable arc-shaped force block 11 resets, and the arc-shaped force block 11 drives the connecting rod 12 and the top plate 13 to move downward, so that the top plate 13 abuts against the upper mold base 3 again. There is no need for the operator to manually reset the top plate 13. By inserting the plug rod 18 into the plug hole 20 opened at the top of the adjusting rod 9, the position of the adjusting rod 9 is locked, preventing the adjusting rod 9 from sliding inside the baffle 8, and ensuring the stability of the adjusting rod 9 when in use or not in use. By setting a reset spring 21, when the pull block 19 drives the plug rod 18 to move, the elastic force of the reset spring 21 can make the plug rod 18 automatically reset to the initial position when not subjected to external force, which facilitates quick locking of the position of the adjusting rod 9. By setting the plug rod 18 to slide in the plug hole 20, and the outer diameter of the plug rod 18 is adapted to the inner diameter of the plug hole 20, the plug rod 18 can be stably inserted into the plug hole 20 without shaking or falling off.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
