Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical moulds, in particular to a powder metallurgical mould support. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metallic powder) as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. Powder metallurgy is similar to the production of ceramics, both of which belong to powder sintering technology. The powder metallurgy pressing mold is the main tool for powder pressing. The mold forms the shape of the manufactured part by pressing the powder in the cavity, which is related to the quality and safety of the production of powder metallurgy products.

[0003] The following problems often occur during the use of powder metallurgy mold supports:

[0004] 1. Common powder metallurgy mold supports cannot be demolded after powder metallurgy pressing is completed. Usually, they are demolded by manual knocking, which not only increases the labor of workers, but also greatly prolongs the demolding time;

[0005] 2. Common powder metallurgy mold supports are prone to displacement during the powder pressing process if the mold is not fixed, affecting the quality of powder metallurgy product production. Utility Model Content

The support 2 is provided with a support plate 1 at the upper end, and the bracket 3 is provided at the lower end of the support 2. The upper end of the support plate 1 is provided with a first cylinder 4, and the output end of the first cylinder 4 is provided with an upper pressure plate 5. The upper pressure plate 5 is provided with sliding plates 6 at both ends. The upper end surface of the support 2 is provided with a second cylinder 8, a mold block 10 and a clamping plate 7. The output end of the second cylinder 8 is provided with a push plate 9, and the lower end of the push plate 9 is provided with a connecting oblique block 18. The clamping plate 7 is located at the front and rear ends of the mold block 10, and the second cylinder 8 is located at the right end of the mold block 10. When in use, the product The product material is poured into the mold block 10, and the turning handle 12 is turned to rotate the bidirectional threaded rod 14, so that the clamping plate 7 moves toward the mold block 10, and the mold block 10 is clamped and fixed. The first cylinder 4 is driven to press the upper pressure plate 5 downward to press the material into shape. After the production is completed, the second cylinder 8 is driven to move the push plate 9 and the connecting inclined block 18. Since the connecting inclined block 18 is longer than the push plate 9, the connecting inclined block 18 touches the top column 17 first, and the top block 13 is lifted upward, so that the product inside the mold block 10 is separated from the mold block 10, which is convenient for taking out. When resetting, the reset spring 16 is used to move the top block 13 downward and automatically restore it to its original state.

[0021] Furthermore, a first sliding groove 61 is provided on the inner wall of the support plate 1 , and the sliding plate 6 is slidably connected to the support plate 1 via the first sliding groove 61 . By providing the first sliding groove 61 and the sliding plate 6 , the upper pressing plate 5 can move more stably.

[0022] Furthermore, a bidirectional threaded rod 14 and a sliding rod 15 are provided at the lower end of the clamping plate 7, the clamping plate 7 is threadedly connected to the bidirectional threaded rod 14, the clamping plate 7 is slidably connected to the sliding rod 15, a second slide groove 11 is opened inside the support 2, and the number of the second slide grooves 11 is set to two, and a turning handle 12 is provided at the front end of the bidirectional threaded rod 14. When clamping, the turning handle 12 is rotated to drive the bidirectional threaded rod 14 to rotate. Since the threads of the bidirectional threaded rod 14 are in opposite directions, the clamping plates 7 move towards each other to clamp and fix the mold block 10.

[0023] Furthermore, a push plate 9 is provided at the output end of the second cylinder 8, and a connecting inclined block 18 is provided at the lower end of the push plate 9. The connecting inclined block 18 is fixedly connected to the push plate 9.

The first cylinder 4 is driven to press the upper pressure plate 5 downward. By setting the sliding plate 6 and the first slide groove 61, the upper pressure plate 5 is made to move more stably. The second cylinder 8 is driven to move the push plate 9 and the connecting inclined block 18. The length of the connecting inclined block 18 is longer than that of the push plate 9. The top block 13 is lifted to demold the product and the mold block 10. Then the push plate 9 pushes the mold block 10 to move and push it to the left. Since the support plate 1 easily blocks the staff from loading materials and it is inconvenient to take the mold block 10, the mold block 10 is pushed after the production is completed to facilitate material removal.
