Description

Technical Field

[0001] This utility model relates to the field of injection molding molds, specifically to an injection molding mold structure with precision guiding components. Background Technology

[0002] Injection molding dies are tools used for the mass production of plastic parts. Molten plastic is injected into the mold cavity, and after cooling, a product with a fixed shape is obtained. Molds are usually made of steel or aluminum alloy, and are characterized by high precision, durability, and wide application in industries such as home appliances, automobiles, and daily necessities. They are characterized by high efficiency, low cost, and good consistency.

Injection molding is performed in a relatively vacuum environment, improving the bonding strength between metal and plastic.

[0004] The aforementioned device does not include components for precise positioning. When the upper and lower molds are joined, without the assistance of precise positioning components, the position of the joined upper and lower molds is easily offset, which will lead to deviations in the later molded parts. Therefore, to address the above problem, an injection molding mold structure with precise guiding components is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technology, the existing devices do not have components for precise positioning. When the upper and lower molds are combined, if there are no components for precise positioning, the position of the upper and lower molds will easily shift, which will lead to deviations in the parts formed later. This utility model proposes an injection molding mold structure with a precision guiding component.

[0006] The technical solution adopted by this utility model to solve its technical problem is: the injection molding mold structure with precision guiding components described in this utility model includes a lower body; the top of the lower body is fixedly connected to an upper body, the bottom of the upper body at the middle position is fixedly connected to the top of the upper mold, the top of the lower body is provided with a lower mold, and the top of the lower body is provided with a precision positioning and guiding mechanism.

The positioning rods are inserted into the fixed plate, and the fixed plate is slidably connected to the positioning rods. The front end of the fixed plate is fixedly connected to the rear end of the lower mold.

[0008] Preferably, a reset spring is sleeved on the outer side of the positioning rod near the upper position, the top end of the reset spring is fixedly connected to the bottom end of the pull plate, and the bottom end of the reset spring is fixedly connected to the top end of the fixing plate.

[0009] Preferably, the left and right sides of the top of the lower body are also provided with fixed sleeve rods, and the top of the lower body is fixedly connected to the bottom of the fixed sleeve rod. The bottom of the positioning rod is inserted into the fixed sleeve rod, and the positioning rod is slidably connected to the fixed sleeve rod.

[0010] Preferably, the top end of the fixing plate is fixedly connected to the bottom end of the second guide rod, a pull plate is sleeved on the outer side of the second guide rod, and the pull plate is slidably connected to the second guide rod. The top end of the second guide rod is fixedly connected to the bottom end of the positioning block.

[0011] Preferably, guide rails are also provided on the left and right sides of the top of the lower body, and the top of the lower body is fixedly connected to the bottom of the guide rail. A first guide moving block is sleeved on the outside of the guide rail, and the guide rail is slidably connected to the first guide moving block.

[0013] The advantages of this utility model are:

[0014] 1. This utility model achieves precise positioning through the structural design of the precise positioning guide mechanism, solving the problem that existing devices do not have components for precise positioning. When the upper and lower molds are merged, if no precise positioning components are provided to assist, the position of the upper and lower molds will easily shift, which will lead to deviations in the later formed parts. This invention reduces the deviation of parts.

[0015] 2. This utility model, through the structural design of a precise positioning and guiding mechanism, achieves the function of facilitating subsequent demolding. It solves the problem that existing devices do not have components for easy demolding. Because the lower mold is below the upper mold after shaping, the upper mold is prone to obstructing the demolding process, thus improving convenience. Attached Figure Description

[0025] The precise positioning guide mechanism includes a pull plate 15, which is located at the rear end of the lower mold 4. Positioning rods 16 are also provided on the left and right sides of the bottom end of the pull plate 15. The bottom end of the pull plate 15 is fixedly connected to the top end of the positioning rods 16. The positioning rods 16 are inserted into the fixed plate 17 and are slidably connected to the fixed plate 17. The front end of the fixed plate 17 is fixedly connected to the rear end of the lower mold 4. The inner wall of the fixed plate 17 is circular.

[0026] During operation, pull plate 15 upwards, causing positioning rod 16 to move synchronously. When positioning rod 16 moves, it will move along the inside of fixed plate 17.

[0027] Furthermore, a return spring 18 is sleeved on the outer side of the positioning rod 16 near the upper position. The top end of the return spring 18 is fixedly connected to the bottom end of the pull plate 15, and the bottom end of the return spring 18 is fixedly connected to the top end of the fixing plate 17. The positioning rod 16 is a round rod design.

[0028] When in operation, the upward movement of the pull plate 15 will cause the return spring 18 to be stretched and extended.

[0029] Furthermore, fixed sleeve rods 19 are also provided on the left and right sides of the top of the lower body 1, and the top of the lower body 1 is fixedly connected to the bottom of the fixed sleeve rod 19. The bottom of the positioning rod 16 is inserted into the fixed sleeve rod 19, and the positioning rod 16 is slidably connected to the fixed sleeve rod 19. The inner wall of the fixed sleeve rod 19 is circular.

[0030] During operation, when the pull plate 15 is released, the return force of the return spring 18 causes the positioning rod 16 to be inserted into the fixed sleeve rod 19 for precise positioning and fixation.

[0031] Furthermore, the top end of the fixing plate 17 is fixedly connected to the bottom end of the second guide rod 20, a pull plate 15 is sleeved on the outside of the second guide rod 20, and the pull plate 15 is slidably connected to the second guide rod 20. The top end of the second guide rod 20 is fixedly connected to the bottom end of the positioning block 21. The second guide rod 20 is a circular rod design.

[0032] When in operation, the pull plate 15 is pulled upward, and the pull plate 15 will move along the outside of the second guide rod 20. The positioning block 21 at the top of the second guide rod 20 is used to limit and block the position of the pull plate 15 to prevent the pull plate 15 from falling off the outside of the positioning block 21.

[0033] Furthermore, guide rails 10 are also provided on the left and right sides of the top of the lower body 1, and the top of the lower body 1 is fixedly connected to the bottom of the guide rail 10. A first guide moving block 11 is sleeved on the outside of the guide rail 10, and the guide rail 10 is slidably connected to the first guide moving block 11. The top of the first guide moving block 11 is fixedly connected to the bottom of the fixing rod 12, and the top of the fixing rod 12 is fixedly connected to the bottom of the lower mold 4. The guide rail 10 has a T-shaped design.

[0034] During operation, the lower mold 4 is pushed to the bottom of the upper mold 3. When the lower mold 4 is pushed to the bottom of the upper mold 3, the first guide moving block 11 at the bottom of the fixed rod 12 moves along the outside of the guide rail 10. The accuracy of the position during movement is ensured by the cooperation of the guide rail 10 and the first guide moving block 11.

[0035] Furthermore, the upper mold 3 is also provided with second guide moving blocks 13 on the left and right sides, and the upper mold 3 is fixedly connected to the second guide moving blocks 13.

The first guide rod 14 is a circular rod design.

[0036] When in operation, the upper body 2 starts, which drives the upper mold 3 to move to the top of the lower mold 4. When the upper mold 3 moves downward, it drives the second guide moving block 13 to move precisely downward along the outside of the first guide rod 14 until the upper mold 3 and the lower mold 4 are merged.

[0037] Working principle: When positioning and movement are required, first pull the pull plate 15 upward, causing the positioning rod 16 to move synchronously. When the positioning rod 16 moves, it will move along the inside of the fixed plate 17. At the same time, the upward movement of the pull plate 15 will cause the return spring 18 to be stretched and extended. Similarly, when the pull plate 15 is pulled upward, it will move along the outside of the second guide rod 20. The positioning block 21 at the top of the second guide rod 20 is used to limit and block the position of the pull plate 15, preventing the pull plate 15 from disengaging from the outside of the positioning block 21. Then, push the lower mold 4 to the bottom of the upper mold 3. When the lower mold 4 is pushed to the bottom of the upper mold 3, it will cause... The first guide moving block 11 at the bottom of the fixed rod 12 moves along the outside of the guide rail 10. The cooperation between the guide rail 10 and the first guide moving block 11 ensures the accuracy of the position during movement. When the positioning insert 16 moves to the top of the fixed plate 17, the pull plate 15 is released. Under the return force of the return spring 18, the positioning insert 16 is driven to insert into the fixed sleeve rod 19 for precise positioning and fixation. Then the upper body 2 is started, which drives the upper mold 3 to move to the top of the lower mold 4. When the upper mold 3 moves downward, it drives the second guide moving block 13 to move precisely downward along the outside of the first guide rod 14 until the upper mold 3 and the lower mold 4 are merged.
