Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an adjustable mold sealing tension locking tool and a mold. Background Art

[0002] Since the materials and parts in the manufacturing process of semiconductors, chips, equipment, etc. are mostly ring-shaped or circular, this tool is widely used in mold sealing. It is a two-way torque pull between two threads. The locking force formed is greater than the unidirectional torque of a thread, and the mold has better sealing. It is more reliable in production applications. The operation is very convenient, stable and reliable. In the manufacturing of semiconductor product equipment, the density, corrosion resistance, material consistency, wear resistance and other requirements of ceramic and precious metal parts are very high. In the molding of ceramic and precious metal billets, if the mold has poor sealing under high pressure above 100Mpa by wet water pressure, hydraulic pressure, gas pressure and other static pressing, the product will be scrapped due to water pollution and the product will have poor performance in later applications. Therefore, most of the early manufacturing and processing processes of ceramic and precious metal parts need to be protected and sealed to improve the stability of molding processing. For example, the plasma etching chamber of semiconductor etching equipment is in a high-density, high-corrosion, and high-activity plasma environment. The chamber and its components are extremely susceptible to plasma corrosion. In order to extend the service life of these components, it is often necessary to form good density and stability during the processing of aluminum-based materials (aluminum and aluminum alloys). Then, the surface is anodized, ceramic sprayed, and other means are used to effectively reduce the corrosion of the chamber and other aluminum-based materials by plasma.

[0003] The existing Chinese patent with publication number CN106089878A discloses a locking device and its application. The locking device includes a locking seat, an outer brake and an inner brake. The outer brake is assembled in the locking seat, and the inner brake is assembled on the inner side of the outer brake; the inner brake includes a left inner brake and a right inner brake which are semi-circular respectively, and also includes an internal adjustment mechanism for adjusting the left inner brake and the right inner brake to cooperate for locking adjustment.

[0004] As the requirements of semiconductor manufacturing processes continue to increase, the requirements for processing before and after part forming are getting higher. The integrity and consistency of product materials are crucial for special cavity parts. During the mold sealing process, if the seal is not good, water will enter the mold cavity, and the product will be scrapped. Therefore, it is necessary to provide an adjustable mold seal tension locking tool that is easy to use, has good sealing, high production efficiency, and can easily obtain better product quality.

It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0031] Example 1

[0032] like Figure 1 As shown, an adjustable mold sealing tension locking tool provided by the utility model includes: a rod-shaped iron wire 1, a right-side tightening ring 3, a spiral screw 4 and a left-side tightening ring 7. The rod-shaped iron wire 1 is ring-shaped, and the two ends of the rod-shaped iron wire 1 are respectively installed with a right-side fixed end 2 and a left-side fixed end 5, the right-side tightening ring 3 is installed on the right-side fixed end 2, and the left-side tightening ring 7 is installed on the left-side fixed end 5. The right-side tightening ring 3 and the left-side tightening ring 7 are respectively matched with the two end threads of the spiral screw 4, and the right-side tightening ring 3 and the left-side tightening ring 7 can approach or move away from each other.

[0033] like Figure 2 As shown, the rod-shaped iron wire 1 can be two parallel iron wires, and the upper and lower sides of the right fixed end 2 are respectively fixedly connected to the two iron wires by welding. The two iron wires of the rod-shaped iron wire 1 pass through the upper and lower sides of the left fixed end 5, respectively, and the upper and lower sides of the left fixed end 5 are fastened to the iron wires by locking nuts 6. The locking nut 6 is set on the left fixed end 5, and the length of the left side of the rod-shaped iron wire 1 can be quickly adjusted to adapt to the size required by different annular molds by loosening the locking nut 6.

[0034] like Figure 3 As shown, the right tension ring 3 and the left tension ring 7 have the same structure. The left tension ring 7 includes: a pull ring and a connecting part. The connecting part is provided with a threaded hole inside. The threaded hole matches the threaded rod of the spiral screw 4. The left tension ring 7 can be close to or away from the spiral screw 4. A through hole is provided in the middle of the left fixed end 5. The connecting part of the left tension ring 7 is inserted into the through hole. A convex part is formed on the side of the connecting part away from the pull ring. The convex part is tightly matched with the left fixed end 5. The distance between the right tension ring 3 and the left tension ring 7 does not exceed 60mm. When pre-adjusting the left tension ring 7, the distance from the right side can be controlled within 30mm. The outer cover of the mold structure is a soft (rubber) material with a certain buffering and telescopic performance. Under normal circumstances, it is also safer to stagger and lock the two tools at the same time.

[0035] The rod-shaped iron wire 1 is fixed to the right fixed end 2 by welding to form a right-side tensioning tool. The other end of the rod-shaped iron wire 1 is fixed to the left fixed end 5 to form a left-side tensioning tool. The left-side tensioning tool and the right-side tensioning tool are connected together by a spiral screw 4. The left side of the spiral screw 4 is connected to the left-side tensioning ring 7 on the left fixed end 5, and the right side is connected to the right-side tensioning ring 3 on the right fixed end 2. The tensioning ring and the spiral screw 4 form a left-right tensioning force by twisting the thread, and the left side is tightened to the left, and the right side is tightened to the right.

[0036] like Figure 4 As shown, the method of use of the present application is as follows: put the rod-shaped iron wire 1 on the outside of the mold, loosen the locking nut 6 on the left fixed end 5 to roughly adjust the length of the rod-shaped iron wire 1 that needs to match the outer dimensions of the mold, and tighten the upper and lower screws of the locking nut 6 to tightly fix the left fixed end 5 and the left end of the rod-shaped iron wire 1 together. By tightening the left tightening ring 7 outwards and driving the left fixed end 5 to form a leftward tightening force, by tightening the right tightening ring 3 outwards and driving the right fixed end 2 to form a rightward tightening force, repeatedly tighten the left tightening ring 7 and the right tightening ring 3 to achieve a fast and effective locking and sealing effect, lock the upper end of the mold to form a seal, and lock the lower end of the mold to form a seal.

[0037] The left fixed end 5 of the present application can quickly adapt the size of annular molds of different sizes and lock them to form a seal, with high operating efficiency. The left and right sides form a pulling force, which is more evenly and more stable than other unidirectional tension locks, so the sealing is better and the operating production efficiency is high. One tool can be applied to molds of different sizes, and the adaptability is very high. The present application is easy to use, because the two threads in both directions are pulled and locked, the sealing is good and stable, the operating efficiency is high, it is easy to obtain better product quality, reduce the clamping time and other advantages, and save the company's costs.

[0038] Variations

[0039] Based on Example 1, the rod-shaped iron wire 1 can also be a folded iron wire, and the upper and lower sides of the right fixed end 2 are fixedly connected to the folded round bend of the iron wire by welding. The two ends of the iron wire pass through the upper and lower sides of the left fixed end 5 respectively, and the upper and lower sides of the left fixed end 5 are fastened to the iron wire by locking nuts 6.

[0040] Example 2

[0041] like Figure 5 and 6As shown, according to a mold provided by the utility model, the adjustable mold sealing tension locking tool of embodiment 1 is used, and also includes an inner mold 8 and an outer mold 9, the outer mold 9 is sleeved on the outer side of the inner mold 8, and the adjustable mold sealing tension locking tool is sleeved on the outer side of the outer mold 9. The outer mold 9 includes a mold outer rubber sleeve, and the mold outer rubber sleeve cooperates with the inner mold 8 to form a mold cavity, and the parts are arranged in the mold cavity. One or more adjustable mold sealing tension locking tools are arranged on the outer side of the sealing port 10 of the mold cavity, which locks the upper end of the mold to form a seal, and locks the lower end of the mold to form a seal.

[0042] The adjustable mold seal tension locking tool of the present application is widely used, mainly for circular isostatic pressing molds, sealing of circular charging equipment, and other circular precious metals that require rapid locking of equipment. Ceramic isostatic pressing molds are currently the most widely used, and the length of the wire depends on the size of the mold. The length can be unlimited according to the size of the mold. It is more convenient to use when the diameter is greater than 150mm. At present, the maximum diameter is 300mm-2000mm.

[0043] In the mold filled with powder, loosen the locking nut 6 on the left fixed end 5 to roughly adjust the length of the rod-shaped iron wire 1 that needs to match the outer dimensions of the mold, and tighten the upper and lower screws of the locking nut 6 to tightly fix the left fixed end 5 and the left end of the rod-shaped iron wire 1 together. By tightening the left tightening ring 7 outward and driving the left fixed end 5 to form a leftward tightening force, and by tightening the right tightening ring 3 outward and driving the right fixed end 2 to form a rightward tightening force, repeatedly tighten the left tightening ring 7 and the right tightening ring 3 to achieve a fast and effective locking and sealing effect. After the product is processed, the tool can be quickly loosened by unscrewing the left tightening ring 7 and the right tightening ring 3 inward.

[0044] Furthermore, the upper and lower ports of the mold, and even the connection and fixing points of the inner and outer molds, can be sealed with an adjustable mold seal and a tension locking tool to form a reliable seal. After the mold processes the product, the tool can be quickly released, and the operation and production efficiency are high.

[0045] The present application has a large locking force in high-strength water pressure mold molding, so the sealing is good and the operating efficiency is high, which solves the problem of water entering the mold cavity due to poor sealing and the product being scrapped.
