Description

Technical Field

[0001] This utility model relates to the field of mold opening tooling technology, and in particular to an auxiliary mold opening tooling fixture for vulcanizing molds. Background Technology

[0002] Mold making fixtures refer to a series of special tools and equipment used in the production process of mold making or injection molding to ensure accurate mold positioning, convenient operation, and improved production efficiency and quality. These fixtures and equipment usually include mold clamps, positioning devices, guiding devices, cooling systems, etc. They work together to achieve precise mold manufacturing and stable product production.

[0003] For the production of large-scale precision skeleton rubber composite parts, due to the inclusion of metal skeletons in the rubber parts, the vulcanizing machine alone cannot automatically open the mold. Currently, most of the mold opening is still done manually using pry bars. Since the molds for these rubber composite parts are generally large and heavy, manual mold opening using pry bars requires considerable strength. Furthermore, the presence of metal skeletons in the product can easily cause the mold to jam, making demolding difficult. The mold opening process is time-consuming, labor-intensive, and can easily damage the mold surface.

[0004] To address this, an auxiliary mold-opening fixture for vulcanizing molds is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary mold opening tooling fixture for vulcanizing molds, so as to solve the problems mentioned in the background art that rubber composite molds are generally large and heavy, and mold opening is done manually using pry bars. This requires a lot of strength from the workers, and because the products contain metal skeleton parts, the mold is easy to get stuck, making demolding difficult. The mold opening takes a long time, which is time-consuming and labor-intensive, and it is also easy to cause wear on the mold surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary mold opening fixture for vulcanizing molds, comprising a fixture platform, a support rod fixedly connected to the top of the fixture platform, a pallet platform fixedly connected to the top of the support rod, a lower mold and an upper mold placed on the top of the pallet platform, and a groove provided on the lower mold; an auxiliary mold opening assembly for separating the lower mold and the upper mold is provided on the fixture platform, the auxiliary mold opening assembly includes a push plate slidably connected to the support rod, a push rod for pushing the upper mold is provided on the push plate, a movable clamping block for clamping the lower mold is provided on the pallet platform, and a bending plate is fixedly connected to the movable clamping block.

[0007] Preferably, the top of the pallet platform is provided with several long grooves, and a roller for mold sliding is rotatably connected in the long grooves.

[0008] Preferably, a limiting groove is provided on the pallet platform, and the movable clamping block is slidably connected in the limiting groove. A motor is fixedly installed on the pallet platform, and a bidirectional threaded rod is fixedly connected to the output shaft of the motor. The bidirectional threaded rod is threadedly connected to the movable clamping block.

[0009] Preferably, the bending plate is provided with an arc-shaped opening, and the push rod is slidably connected in the arc-shaped opening. Both the push plate and the support plate are provided with sliding grooves that are adapted to the push rod, and the push rod moves through the sliding grooves.

[0010] Preferably, a limiting frame is fixedly installed at the top of the push rod, and a top rod is slidably connected to the limiting frame. A threaded rod is threadedly connected to the top rod, and the threaded rod is rotatably connected to the limiting frame.

[0011] Preferably, the bending plate has an arc-shaped opening, and the push rod is slidably connected in the arc-shaped opening. A stop block is fixedly installed on the support plate, and the top ends of the push rod and the top rod are provided with anti-slip pads.

[0012] Preferably, a cylinder is fixedly installed on the fixture platform, and the output end of the cylinder is fixedly connected to the push plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses an auxiliary mold opening component to move the mold to the mold opening position with the help of a roller. After the lower mold is limited by the moving clamping block, the cylinder is activated to push the push plate to move, so that the push rod and the ejector rod move upward to contact the upper mold and apply a pushing force, thereby separating the upper mold and the lower mold to achieve the purpose of mold opening. The entire device does not require manual prying of the mold, which saves time and effort, has high mold opening efficiency, and is not prone to mold jamming.

[0015] 2. This utility model allows for free adjustment of the distance between the movable clamping blocks to adapt to the mold width, and adjustment of the position of the ejector rod in the limiting frame to adapt to the mold length, thereby adjusting the length and width to adapt to different mold models, making the device more adaptable.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1 to 4As shown in the figure, a specific embodiment of this utility model provides an auxiliary mold opening fixture for vulcanizing molds, including a fixture platform 1. A support rod 2 is fixedly connected to the top of the fixture platform 1, and a pallet platform 3 is fixedly connected to the top of the support rod 2. A lower mold 4 and an upper mold 5 are placed on the top of the pallet platform 3, and the lower mold 4 is provided with a groove 6. The fixture platform 1 is provided with an auxiliary mold opening component for separating the lower mold 4 and the upper mold 5. By setting the auxiliary mold opening component, the mold opening can be replaced by manual operation, improving the mold opening efficiency, avoiding the mold jamming phenomenon that is easily caused by manual use of pry bars, and reducing damage to the mold surface. The auxiliary mold opening component includes a push plate 7 slidably connected to the support rod 2. The push plate 7 is provided with a push rod 8 for pushing the upper mold 5. The pallet platform 3 is provided with a movable clamping block 9 for clamping the lower mold 4. A bending plate 10 is fixedly connected to the movable clamping block 9.

[0025] like Figures 1 to 4 As shown, specifically, during the mold opening operation, the mold must first be placed on the top of the pallet platform 3. The top of the pallet platform 3 has several long slots 11, and rollers 12 for mold sliding are rotatably connected in these slots. A stop block 20 is fixedly installed on the pallet platform 3. The rollers 12 in the long slots 11 at the top of the pallet platform 3 facilitate the movement of the mold placed on top of the pallet platform 3. The mold slides on the rollers 12. During the mold sliding process, a moving clamping block 9 enters the groove 6 on the lower mold 4. The cooperation between the moving clamping block 9 and the groove 6 limits the movement of the lower mold 4. A limiting groove is provided on the pallet platform 3. 13, and the movable clamping block 9 is slidably connected in the limiting groove 13. The motor 14 is fixedly installed on the support plate 3, and the output shaft of the motor 14 is fixedly connected to the bidirectional threaded rod 15. The bidirectional threaded rod 15 is threadedly connected to the movable clamping block 9, and the distance between the movable clamping blocks 9 can be adjusted according to the size of the mold. The motor 14 is started to drive the bidirectional threaded rod 15 to rotate, so that the movable clamping block 9 moves in the limiting groove 13. The distance between the movable clamping blocks 9 can be determined according to the width of the mold, so as to realize the matching and limiting of the lower mold 4. The mold slides to the stop block 20 and stops moving under the obstruction of the stop block 20.

[0026] like Figures 1 to 4As shown, specifically, a limiting frame 17 is fixedly installed at the top of the push rod 8, and a push rod 18 is slidably connected in the limiting frame 17. A threaded rod 19 is threadedly connected to the push rod 18, and the threaded rod 19 is rotatably connected to the limiting frame 17. After adjusting the width of the mold by moving the clamping blocks 9, rotating the threaded rod 19 allows the push rod 18 to move within the limiting frame 17. Thus, by adjusting the position of the push rod 18 in the limiting frame 17, the distance between the push rod 18 and the other push rod 8 is adjusted. That is, by adjusting the distance between the push rod 18 and the other push rod 8, the length of the mold is adapted. And all of this is achieved by adjusting the length to... The device is designed to accommodate molds of different sizes, with varying widths to enhance its adaptability. The bending plate 10 has an arc-shaped opening, in which the push rod 8 is slidably connected. Both the push plate 7 and the support plate 3 have grooves 16 that mate with the push rod 8, with the push rod 8 moving through the grooves 16. The grooves 16 allow the moving clamp 9 to move via the bending plate 10 when its position is adjusted, ensuring a constant relative position between the push plate 7 and the moving clamp 9. This keeps the push rod 8 always positioned below the upper mold 5. This facilitates the subsequent pushing of the upper mold 5 by the push rod 8, and the change in the position of the push rod 8 will also cause the position of the limiting frame 17 to change, thereby changing the position of the ejector rod 18. This makes it easier for the ejector rod 18 to push the upper mold 5 with the other push rod 8. The top of both the push rod 8 and the ejector rod 18 are provided with anti-slip pads. The anti-slip pads increase the friction when the push rod 8 and the ejector rod 18 move and come into contact with the upper mold 5 at the top. A cylinder 21 is fixedly installed on the fixture table 1, and the output end of the cylinder 21 is fixedly connected to the push plate 7. In the above process, after the mold position is set and the lower mold 4 is limited, the cylinder 21 is activated to push the push plate 7 at the top upward. The push plate 7 moves upward, pushing the push rod 8 at the top to move upward. At the same time, the push rod 18 in the limiting frame 17 at the top of the push rod 8 on one side moves upward. At this time, the push rod 8 and the push rod 18 move upward and contact the upper mold 5 and apply a pushing force to it. Since the lower mold 4 is limited by the moving clamping block 9, the upper mold 5 separates from the lower mold 4 under the action of the push rod 8 and the push rod 18, thus completing the mold opening. After the product in the mold is taken out, the cylinder 21 drives the push plate 7 to move downward and reset. Thus, the push rod 8 and the push rod 18 move downward and reset, driving the upper mold 5 to move downward and re-engage with the lower mold 4. Then the mold can be moved to remove it.
