Description

Technical Field

[0001] This utility model relates to the field of sandblasting protective tooling technology, specifically to a sandblasting protective tooling for metal molds. Background Technology

[0002] Metal mold sandblasting protective fixtures are specialized equipment or devices used to protect metal molds from damage or contamination during sandblasting. Sandblasting is a common surface treatment process that cleans, polishes, or grinds metal surfaces by high-speed jetting of abrasive particles. Protective fixtures extend mold life, improve production efficiency, and protect the environment and employee safety. Patent number CN202421860462.6 discloses a metal mold sandblasting protective fixture that, through the inclusion of fixing components, allows for the fixing and sandblasting of molds of various shapes, optimizing the frequent changes of fixing clamps required in traditional technologies. The rotatable fixing components also allow for more efficient sandblasting of multiple surfaces of the mold, thus improving the device's practicality. However, in the process of using the metal mold sandblasting protective fixture, operators need to manually rotate multiple handles to rotate the threaded rod before the two sets of housings can be joined together for protection, which is inconvenient. Therefore, we propose a metal mold sandblasting protective fixture. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a protective tooling for sandblasting metal molds.

[0004] The technical solution adopted by this utility model to solve its technical problem is a metal mold sandblasting protective tooling, including a housing A. The bottom surface of the housing A is equipped with an adjustable rail seat, and an adjustable slider is slidably installed on the inner side of the rail seat. The top surface of the slider is equipped with a housing B that fits with the housing A by bolts, and a lead screw that is screwed and connected to the slider is rotatably installed on the inner side of the rail seat. The outer wall surface of the housing A is equipped with a worm gear reducer that is driven by the lead screw, and a servo motor is installed at the power input end of the worm gear reducer.

[0005] The outer peripheral surface of housing A is fitted with a lug for support, and there are multiple sets of lugs. The outer peripheral surface of housing B is fitted with lugs corresponding to the lugs, and there are multiple sets of lugs. The inner side of the lug is fitted with a T-shaped shaft that is inserted and connected to the lugs by bolts.

[0006] By adopting the above technical solution, during the use of the protective tooling for sandblasting metal molds, the servo motor on the outside of housing A can operate and drive the lead screw inside the rail seat to rotate under the operation of the worm gear reducer. This allows the lead screw to be screwed together with the sliding slider inside the rail seat, causing the slider to slide and move inside the rail seat. The slider's movement facilitates the movement of housing B closer to housing A, allowing housing A and housing B to merge together and cover the metal mold, making subsequent sandblasting easier. Moreover, the electric operation method of merging is more convenient.

[0007] As housing B moves closer to housing A with the slider, multiple sets of lugs on the outer periphery of housing A provide convenient support for the T-shaped shaft. At the same time, the T-shaped shaft can easily interlock and slide with the lugs on the outer periphery of housing B, which facilitates guiding and limiting housing B as it approaches housing A. This allows housing B to dock and merge more stably with housing A, reducing the possibility of misalignment between housing B and housing A.

[0008] Specifically, the T-shaped shaft has an arc-shaped groove on its outer periphery for limiting the position, and the ear block has a locking pin that fits into the arc-shaped groove screwed onto its outer periphery.

[0009] By adopting the above technical solution, when the T-shaped shaft slides in the lug, the locking pin screwed on the outer periphery of the lug can easily engage with and slide with the arc groove, and can limit the movement between the T-shaped shaft and the lug, thereby reducing the possibility of separation between the two, so that the lug can stably engage with and slide with the T-shaped shaft.

[0010] Specifically, the end of the ear seat near the ear block is equipped with a spring for cushioning, and the end of the spring away from the ear seat is equipped with a washer located on the outer periphery of the T-shaped shaft.

[0011] By adopting the above technical solution, when shell B and shell A are combined, the spring on the outer peripheral lug of shell A can provide elastic thrust to the washer, so that when shell B and shell A are combined, the lug will first drive the washer to abut against each other, which can provide a certain buffer force when shell B and shell A are combined, so that the two can be combined more stably.

[0012] Specifically, a protective rubber ring is adhered to the side of the washer near the lug.

[0013] By adopting the above technical solution, the rubber ring has good elasticity, which helps to reduce the damage caused by the friction between the washer and the lug.

[0014] Specifically, the outer peripheral surface of the housing B is fitted with a sleeve plate that fits with the T-shaped shaft, and there are multiple sets of sleeve plates. A cylindrical seat located on the outer periphery of the T-shaped shaft is fitted between the sleeve plate and the lug.

[0015] By adopting the above technical solution, the outer circumference of the housing B and the sleeve and the cylinder can cooperate with each other to facilitate the assistance of the lugs, so that the T-shaped shaft can more stably guide the movement of the housing B.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of a rail base, slider, lead screw, housing B, worm gear reducer and servo motor, enables the servo motor on the outside of housing A to operate and drive the lead screw inside the rail base to rotate under the operation of the worm gear reducer during the use of the protective tooling for sandblasting metal molds. This allows the lead screw to screw into the slider inside the rail base, causing the slider to slide and move within the rail base. The slider's movement facilitates the movement of housing B towards housing A, allowing housing A and housing B to merge and cover the metal mold, facilitating subsequent sandblasting. Furthermore, the electrically operated merging method is more convenient.

[0018] 2. The technical solution of this application, through the design of ear seats, T-shaped shafts and ear blocks, allows multiple sets of ear seats on the outer periphery of housing A to support the T-shaped shaft as housing B moves closer to housing A with the movement of the slider. At the same time, the T-shaped shaft can easily be inserted and slidably connected with the ear blocks on the outer periphery of housing B, which facilitates guiding and limiting housing B as it moves closer to housing A. This allows housing B to dock and merge more stably with housing A, reducing the possibility of misalignment between housing B and housing A. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a metal mold sandblasting protective fixture, including a housing A1, an adjustable rail seat 2 mounted on the bottom surface of the housing A1, and an adjustable slider 3 slidably mounted on the inner side of the rail seat 2. A housing B7, which fits with the housing A1, is bolted to the top surface of the slider 3. A lead screw 4, which is screwed to the slider 3, is rotatably mounted on the inner side of the rail seat 2. A worm gear reducer 5, which is driven by the lead screw 4, is bolted to the outer wall surface of the housing A1. A servo motor 6 is mounted at the power input end of the worm gear reducer 5. Ear seats 8, which are multiple sets, are mounted on the outer peripheral surface of the housing A1. Ear blocks 10, which are corresponding to the ear seats 8, are multiple sets, and a T-shaped shaft 9, which is inserted and connected to the ear blocks 10, is bolted to the inner side of the ear seats 8.

[0026] When in use, during the sandblasting protective tooling for metal molds, the servo motor 6 on the outside of housing A1 operates and drives the lead screw 4 inside the rail seat 2 to rotate under the operation of the worm gear reducer 5. This allows the lead screw 4 to be screwed together with the slider 3 inside the rail seat 2, causing the slider 3 to slide and move inside the rail seat 2. The movement of the slider 3 facilitates the movement of housing B7 closer to housing A1, allowing housing A1 and housing B7 to merge together and cover the metal mold, making subsequent sandblasting easier. The electric operation of merging is also more convenient.

[0027] As the slider 3 moves closer to the housing A1, the multiple sets of lugs 8 on the outer periphery of the housing A1 facilitate the support of the T-shaped shaft 9. At the same time, the T-shaped shaft 9 can easily be inserted and slidably connected with the lugs 10 on the outer periphery of the housing B7, which facilitates the guidance and limiting of the housing B7 as it approaches the housing A1. This allows the housing B7 to more stably dock and merge with the housing A1, reducing the possibility of misalignment between the housing B7 and the housing A1.

[0028] like Figure 1 and Figure 3 As shown, the outer periphery of the T-shaped shaft 9 is provided with an arc-shaped groove 13 for limiting the position, and the outer periphery of the ear block 10 is screwed with a locking pin 14 that matches the arc-shaped groove 13.

[0029] When in use, when the T-shaped shaft 9 slides in the lug 10, the locking pin 14 screwed on the outer periphery of the lug 10 can easily engage and slide with the arc groove 13, and can limit the movement between the T-shaped shaft 9 and the lug 10, thereby reducing the possibility of separation between the two, so that the lug 10 can stably engage and slide with the T-shaped shaft 9.

[0030] like Figure 1 and Figure 3 As shown, a spring 15 for cushioning is fitted at one end of the ear seat 8 near the ear block 10, and a washer 16 located on the outer periphery of the T-shaped shaft 9 is fitted at the other end of the spring 15 away from the ear seat 8.

[0031] When in use, when housing B7 and housing A1 are combined, the spring 15 on the outer peripheral lug 8 of housing A1 can provide elastic thrust to the washer 16, so that when housing B7 and housing A1 are combined, the lug 10 will first drive the washer 16 to abut against each other, which can provide a certain buffer force when housing B7 and housing A1 are combined, so that the two can be combined more stably.

[0032] like Figure 1 and Figure 3 As shown, a protective rubber ring 17 is bonded to the side of the washer 16 near the lug 10.

[0033] When in use, the rubber ring 17 has good elasticity, which helps to reduce the damage caused by the friction between the washer 16 and the ear block 10.

[0034] like Figure 1 As shown, the outer peripheral surface of the housing B7 is fitted with a sleeve plate 12 that fits with the T-shaped shaft 9, and there are multiple sets of sleeve plates 12. A cylindrical seat 11 located on the outer periphery of the T-shaped shaft 9 is fitted between the sleeve plate 12 and the lug 10.

[0035] In use, the sleeve plate 12 and the cylinder seat 11 on the outer periphery of the housing B7 can cooperate with the lug 10 to facilitate the lug 10 and enable the T-shaped shaft 9 to guide the movement of the housing B7 more stably.

[0036] The working principle and usage process of this utility model are as follows: In use, the corresponding structural components are first installed in suitable positions. During the sandblasting protective fixture application to the metal mold, the servo motor 6 on the outside of housing A1 operates and, under the operation of the worm gear reducer 5, drives the lead screw 4 inside the rail seat 2 to rotate. This allows the lead screw 4 to screw into the sliding slider 3 inside the rail seat 2, causing the slider 3 to slide within the rail seat 2. The displacement of the slider 3 facilitates the movement of housing B7 closer to housing A1, allowing housing A1 and housing B7 to merge and cover the metal mold, facilitating subsequent sandblasting. The electrically operated merging method is also more convenient. Simultaneously, as housing B7 moves closer to housing A1 with the slider 3, the multiple sets of lugs 8 on the outer periphery of housing A1 provide support for the T-shaped shaft 9. The T-shaped shaft 9 also easily engages and slides with the lugs 10 on the outer periphery of housing B7, facilitating the movement of housing B7 closer to housing A1. The guide limiter allows housing B7 to more stably dock with housing A1, reducing the possibility of misalignment between them. When the T-shaped shaft 9 slides within the lug 10, the locking pin 14 screwed into the outer circumference of the lug 10 easily engages and slides with the arc-shaped groove 13, limiting the movement between the T-shaped shaft 9 and the lug 10 and reducing the possibility of separation. This ensures stable engagement and sliding between the lug 10 and the T-shaped shaft 9. Furthermore, when housing B7 and housing A1 merge, the spring 15 on the outer lug seat 8 of housing A1 provides elastic thrust to the washer 16, causing the lug 10 and washer 16 to abut against each other. This provides a buffering force, ensuring a more stable docking and allowing the sandblasting protective fixture to be used more stably during metal mold sandblasting.
