Description

Technical Field

[0001] This utility model relates to the field of production technology and equipment for armature sealing blocks, and in particular to a jig for loading and unloading armature sealing blocks for rubber coating molding. Background Technology

[0002] Armature sealing block, refer to Figure 9 The process involves placing the armature and the rubber coating over it in a rubber-coated mold for vulcanization molding. After molding, the armature sealing block is removed from the mold. Because multiple armature sealing blocks are placed on the mold, the process of loading and positioning the armature in the mold and removing the molded armature sealing block becomes very slow. The mold requires the vulcanizing machine to wait, leaving it idle and hindering equipment utilization. Furthermore, the high temperature of the freshly molded armature sealing block poses a risk of burns to workers during manual removal. Therefore, a suitable jig is needed to quickly load the armature onto the mold and remove the molded armature sealing block. Summary of the Invention

[0003] Therefore, it is necessary to address the problems of armature loading onto the overmolding mold and removing the molded armature sealing block from the overmolding mold during the production process of armature sealing blocks. This utility model achieves this by providing a jig for loading and unloading armature sealing blocks during overmolding, including a positioning platform and a movable seat for positioning the armature. The positioning platform includes a base and multiple bottom columns fixedly connected to the base. A row of fixing grooves is formed on each bottom column, and the fixing grooves are fixedly engaged with the bottom of the armature. The movable seat includes a lifting plate, and a pair of sliding rods are provided on both sides of the lifting plate. A fitting seat is fixed between the pair of sliding rods. The fitting seat has a sleeve hole corresponding to the fixed groove, and the sleeve hole penetrates the fitting seat. A magnetic suction seat is also movably provided between the pair of sliding rods and between the fitting seat and the lifting plate. The magnetic suction seat includes a movable plate, and a magnetic groove is provided at the bottom of the movable plate. The magnetic groove corresponds one-to-one with the sleeve hole. A magnetic block is fitted in the magnetic groove. When the magnetic suction seat is attached to the fitting seat, the armature or armature sealing block is attracted into the sleeve hole of the fitting seat by the magnetic force of the magnetic block. When the magnetic suction seat is away from the fitting seat, the armature or armature sealing block is released from the sleeve hole of the fitting seat.

[0004] Furthermore, linear bearings corresponding to the slide rod are installed on both sides of the movable plate, and the slide rod is slidably fitted into the linear bearings. Through the linear bearings, a sliding connection is formed between the slide rod and the movable plate. The up-and-down movement of the movable plate is limited by the slide rod, improving the smoothness of the up-and-down sliding of the movable plate. As the movable plate slides, the magnetic seat moves away from or closer to the fitting seat.

[0005] Furthermore, a spring is fitted onto the slide rod, with one end of the spring abutting against the linear bearing and the other end abutting against the bottom of the lifting plate. Through the spring, the movable plate is brought close to and fitted against the fitting seat.

[0006] Furthermore, the upper part of the movable plate is provided with a handle, which is used to lift the movable plate in the lifting direction, moving the movable plate away from the fitting seat, thereby releasing the armature or armature sealing block that is adsorbed in the sleeve hole.

[0007] Furthermore, the movable plate is an aluminum alloy plate.

[0008] Furthermore, the movable plate has first side holes on both sides of the magnetic groove, the first side holes extending through both sides of the movable plate, and an iron rod is fitted inside the first side hole. The magnetic block fixed in the magnetic groove is attracted by the magnetic force of the iron rod, thus better fixing the magnetic block in the magnetic groove.

[0009] Furthermore, the iron rod has an arc-shaped notch corresponding to the shape of the magnetic block. The magnetic block is further fixed in the magnetic groove by the locking fit of the arc-shaped notch with the magnet.

[0010] Furthermore, the fitting seat has connecting holes on both sides corresponding to the slide rod, and a second side hole is provided on the side wall of the connecting hole. The fitting seat is fitted and connected to the slide rod through the connecting holes on both sides, and the fitting seat is threadedly fixed by the fixing screw on the second side hole.

[0011] Furthermore, the bottom of the sleeve hole is provided with a trumpet-shaped guide notch. When the armature positioned on the positioning platform is attracted by the movable seat, the trumpet-shaped guide notch allows the armature to fit better into the sleeve hole and be magnetically attracted by the magnetic suction seat attached to the fitting seat.

[0012] Furthermore, the base has positioning copper blocks corresponding to the slide rods installed on both sides of the base column. These positioning copper blocks have through holes. When the armature positioned on the positioning platform is attracted by the movable seat, the end of the slide rod is inserted into the through hole. After insertion, the positioning effect of the through hole on the slide rod allows the fitting seat on the movable seat to better cooperate with the armature, thereby achieving the overall and rapid attraction of the armatures fixed in a row on the base column into the sleeve hole.

[0013] In this invention, when the armature is fed, it is first positioned by the positioning table. Since the positioning table and the rubber-coating mold are independent of each other, the feeding of the armature does not affect the simultaneous molding of the armature sealing block by the vulcanizing molding machine. Therefore, the utilization rate of the vulcanizing molding machine can be greatly improved.

[0014] In this invention, the armatures positioned on the positioning platform can be quickly and sequentially attracted into the sleeve holes on the moving platform using the magnetic attraction of a movable seat. The movable seat then rapidly transfers the attracted armatures into the rubber-coating mold. Similarly, the movable seat can also be used to remove the molded armature sealing blocks from the rubber-coating mold using the magnetic attraction. Because batch feeding is possible from the moving platform to the rubber-coating mold, and batch removal of the molded armature sealing blocks from the mold, the efficiency of feeding and removing is greatly improved, time is reduced, and the utilization rate of the vulcanizing molding machine is significantly increased.

[0015] This invention utilizes a positioning platform to first position the armature, and then uses a movable seat to control the attraction force of the magnet seat to load the armature from the positioning platform to the rubber-coating mold, or uses the movable seat to remove the formed armature sealing block from the rubber-coating mold.

Detailed Implementation

[0026] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0027] In this embodiment, the armature sealing block 3, as referred to Figure 9 It includes an armature 31 and a rubber coating 32 wrapped around the armature 31. During the production process, the armature 31 needs to be positioned in the rubber coating molding mold for rubber vulcanization molding. After molding, the molded armature sealing block 3 is taken out from the rubber coating molding mold.

[0028] A jig for the rubber coating molding of an armature sealing block, referring to... Figures 1-3 It includes a positioning platform 1 and a movable seat 2 for positioning the armature 31. The positioning platform 1 and the movable seat 2 can be used separately or together. The purpose of using the positioning platform 1 and the movable seat 2 separately or together is to better solve the problem of feeding or unloading the armature sealing block 3 during the production process.

[0029] Reference Figure 4 The positioning platform 1 includes a base 11 and multiple bottom columns 12 fixedly connected to the base 11. A row of fixing grooves 121 are opened on the bottom columns 12. The fixing grooves 121 are fixedly engaged with the bottom of the armature 31, so that the fixing grooves 121 of the positioning platform 1 can position the armature 31 to be coated into a row, which facilitates the moving seat 2 to adsorb and fix in rows and batches. Since the positioning platform 1 and the coating molding mold are independent of each other, the feeding of the armature 31 does not affect the simultaneous forming of the armature sealing block 3 by the vulcanizing molding machine. Therefore, the utilization rate of the vulcanizing molding machine can be greatly improved.

[0030] Reference Figure 5 , Figure 6The movable seat 2 includes a lifting plate 21. A pair of sliding rods 24 are provided on both sides of the lifting plate 21. A fitting seat 23 is fixed between the pair of sliding rods 24. The fitting seat 23 has a sleeve hole 231 corresponding to the fixing groove 121. The sleeve hole 231 passes through the fitting seat 23. In order to better realize the feeding of the armature 31 into the sleeve hole 231 or the removal of the rubber-coated armature sealing block 3 from the rubber-coated molding mold, a trumpet-shaped guide notch 234 is provided at the bottom of the sleeve hole 231. The guide notch 234 has a guiding function to ensure that the armature 31 or the armature sealing block 3 is quickly guided and fitted. The fitting seat 23 has connecting holes 232 corresponding to the sliding rods 24 on both sides. A second side hole 233 is provided on the side wall of the connecting hole 232. The fitting seat 23 is fitted and connected to the sliding rod 24 through the connecting holes 232 on both sides, and the fitting seat 23 is threadedly fixed by the fixing screw on the second side hole 233, thereby realizing the fixing of the fitting seat 23 on the sliding rod 24.

[0031] A magnetic seat 22 is also movably provided between a pair of sliding rods 24 and between the fitting seat 23 and the lifting plate 21, as shown in the reference. Figure 7 The magnetic base 22 includes a movable plate 221. A magnetic groove 221a is formed at the bottom of the movable plate 221, and the groove 221a corresponds one-to-one with the sleeve hole 231. A magnetic block 225 is fitted into the groove 221a. When the magnetic base 22 is attached to the fitting base 23, the magnetic block 225 can generate sufficient magnetic force within the sleeve hole 231 of the fitting base 23. The armature 31 or armature sealing block 3 is attracted to the sleeve hole 231 of the fitting base 23 by the magnetic force of the magnetic block 225. Within 1, the sleeve hole 231 of the fitting seat 23 is used to attract and fix the armature 31 or the armature sealing block 3. When the magnetic seat 22 is far away from the fitting seat 23, the magnetic block 225 cannot generate enough magnetic force in the sleeve hole 231 of the fitting seat 23, and the armature 31 or the armature sealing block 3 cannot be attracted to the sleeve hole 231 of the fitting seat 23 by the magnetic force of the magnetic block 225. Thus, the magnetic seat 22 can be released from the armature 31 or the armature sealing block 3.

[0032] In this embodiment, in order to better realize the sliding of the movable plate 221, linear bearings 222 corresponding to the slide rod 24 are installed on both sides of the movable plate 221. The slide rod 24 is slidably fitted in the linear bearing 222. Through the linear bearing 222, a sliding connection is formed between the slide rod 24 and the movable plate 221. The up and down movement of the movable plate 221 is limited by the slide rod 24, which improves the smoothness of the up and down sliding of the movable plate 221. As the movable plate 221 slides, the magnetic suction seat 22 moves away from or closer to the fitting seat 23, thereby realizing the control of the adsorption state or release state of the moving seat 2 on the armature 31 or the armature sealing block 3.

[0033] In this embodiment, in order to better control the adsorption or release state of the armature 31 or armature sealing block 3 by the movable seat 2, a spring 25 is sleeved on the slide rod 24. One end of the spring 25 abuts against the linear bearing 222, and the other end of the spring 25 abuts against the bottom of the lifting plate 21. Through the elastic pressing action of the spring 25 on the movable plate 221, the movable plate 221 is close to and attached to the sleeve seat 23. Thus, by using the spring 25, the adsorption state of the armature 31 or armature sealing block 3 by the movable seat 2 can be controlled. Furthermore, a handle 223 is provided on the upper part of the movable plate 221. By lifting the movable plate 221 in the direction of the lifting plate 21 through the handle 223, the movable plate 221 is moved away from the sleeve seat 23, and the armature 31 or armature sealing block 3 adsorbed in the sleeve hole 231 can be released.

[0034] In this embodiment, the movable plate 221 is made of aluminum alloy, which reduces the weight of the movable plate 221 and saves on manufacturing costs. However, since the movable plate 221 is made of aluminum alloy, and aluminum alloy is not a good conductor of magnetism, the magnetic block 225 installed in the magnetic groove 221a lacks the magnetic attraction of the movable plate 221 for the magnetic block 225. Therefore, a first side hole 221b is provided on both sides of the magnetic groove 221a, and the first side hole 221b passes through both sides of the movable plate 221. An iron rod 224 is fitted in the first side hole 221b and the magnetic block 225 is fixed in the magnetic groove 221a. The magnetic attraction of the magnetic block 225 by the iron rod 224 makes the magnetic block 225 better fixed in the magnetic groove 221a. Furthermore, an arc-shaped notch 224a corresponding to the shape of the magnet 225 can be made on the iron rod 224. The magnet 225 can be further fixed in the magnetic groove 221a by the clamping fit of the arc notch 224a with the magnet 225.

[0035] In this embodiment, in order to enable the movable seat 2 to more accurately adsorb the armatures 31 on the positioning platform 1 into the sleeve holes 231 of the fitting seat 23 in batches, the base 11 of the positioning platform 1 is equipped with positioning copper blocks 13 corresponding to the slide rods 24 on both sides of the base column 12. The positioning copper blocks 13 have through holes 131. When the armatures 31 positioned on the positioning platform 1 are adsorbed by the movable seat 2, the end of the slide rod 24 is inserted into the through hole 131. After insertion, the positioning effect of the through hole 131 on the slide rod 24 enables the fitting seat 23 on the movable seat 2 to better cooperate with the armatures 31, thereby realizing the rapid adsorption of the armatures 31 fixed in rows on the base column 12 into the sleeve holes 231.

[0036] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
