[0002] A resistance ring is a ring-shaped device used to control resistance in fluid, material, or mechanical systems. Resistance ring molding equipment heats and melts rubber raw materials through an injection molding machine, then injects them into a specific mold cavity, where they cool and solidify to form a resistance ring of the desired shape and size.

[0003] However, the following problems were found in the implementation of the relevant technologies:

[0004] Existing resistance ring forming equipment relies heavily on manual feeding, which is inefficient and slow. The mold is difficult to switch stations flexibly or connect to other equipment, and the material flow is time-consuming. Furthermore, the lack of precise limiting structure makes the parts prone to deviation, resulting in frequent forming defects. The mold and feeding parts have poor dimensional adaptability, uneven material filling, and easy damage to the material during feeding, leading to a high scrap rate. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a feeding device for a resistance ring forming equipment, including a base plate 1, a base plate 4 fixedly mounted on the lower surface of the base plate 1, a lower mold frame 2 mounted on the upper side of the base plate 1, a groove 11 opened on one side of the upper surface of the base plate 1, and a top plate 47 mounted in the groove 11, electric push rods 31 symmetrically fixedly mounted on the upper surface of the base plate 1, and a pressure plate 3 fixedly mounted on the output end of the electric push rods 31, an upper mold 32 fixedly mounted on the lower surface of the pressure plate 3, and a feed pipe 33 fixedly mounted on the upper surface of the pressure plate 3. After the electric push rods 31 are started, their output end pushes the pressure plate 3 downward, and the upper mold 32 fixed on the lower surface of the pressure plate 3 moves downward to cooperate with the lower mold frame 2 to complete the pressing and forming of the resistance ring. The feed pipe 33 is located on the upper surface of the pressure plate 3 and can convey raw materials into the mold before pressing.

[0023] Specifically, a side block 41 is fixedly provided on one side of the chassis 4, and a motor 42 is fixedly provided on the outer side of the side block 41. The output end of the motor 42 passes through the side block 41 and is fixedly provided with a drive gear 43. The outer surface of the drive gear 43 meshes with the crown gear 44, and the lower surface of the crown gear 44 is rotatably connected to the chassis 4. After the motor 42 is started, its output end drives the drive gear 43 to rotate. Since the drive gear 43 meshes with the crown gear 44, the crown gear 44 rotates.

[0024] Furthermore, a lead screw 45 is fixedly provided on the upper surface of the crown gear 44, and the upper end of the lead screw 45 is rotatably connected to the base plate 1. A lifting bracket 46 is threaded on the outer surface of the lead screw 45, and the upper end of the lifting bracket 46 is fixedly connected to the top plate 47. When the crown gear 44 rotates, it drives the lead screw 45 fixed on its upper surface to rotate synchronously. The lifting bracket 46 threaded on the outer surface of the lead screw 45 will move up and down along its axial direction due to the rotation of the lead screw 45. The upper end of the lifting bracket 46 is fixedly connected to the top plate 47. When the lifting bracket 46 moves up and down, the top plate 47 moves up and down in the groove 11 accordingly.

[0025] Furthermore, a limiting frame 48 is fixedly provided on one side of the lifting bracket 46, and positioning columns 49 are symmetrically fixed on the lower surface of the base plate 1. The positioning columns 49 penetrate the limiting frame 48. The cooperation between the positioning columns 49 and the limiting frame 48 limits the lifting of the top plate 47, ensuring the accuracy of the movement of each component and avoiding molding defects caused by positional deviation.

[0026] It is worth noting that the outer surface dimensions of the top plate 47 are the same as those of the groove 11, and the dimensions of the groove 11 are the same as those of the inner wall of the lower mold frame 2. After the resistance ring is formed in the mold, the top plate 47 rises from the groove 11. Since its outer surface dimensions are the same as those of the groove 11 and the inner wall of the lower mold frame 2, it can push the formed material in the lower mold frame 2 upward to achieve material discharge.

[0027] It is worth noting that guide rails 21 are symmetrically fixed on the upper surface of the base plate 1, and electric sliders 22 are slidably mounted on the upper surface of the guide rails 21. A connecting frame 23 is bolted to the upper surface of the electric slider 22, and the inner side of the connecting frame 23 is fixedly connected to the lower mold frame 2. The guide rails 21 on the upper surface of the base plate 1 cooperate with the electric sliders 22. The electric sliders 22 drive the lower mold frame 2 to slide on the guide rails 21 through the connecting frame 23, which can realize the position adjustment of the lower mold frame 2.

[0028] It is worth mentioning that guide strips 24 are symmetrically fixed on the upper surface of the base plate 1, and sliding blocks 25 are fixed on the outer side of the connecting frame 23. The sliding blocks 25 are locked on the corresponding guide strips 24. The cooperation between the guide strips 24 and the sliding blocks 25 provides guidance for the movement of the connecting frame 23 and the lower mold frame 2, ensuring the smoothness and accurate positioning of the movement process.

[0029] Among them, the electric slider 22, motor 42, and electric push rod 31 are all existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle: After the motor 42 starts, its output end drives the drive gear 43 to rotate. Since the drive gear 43 meshes with the crown gear 44, the crown gear 44 will rotate.

[0031] When the crown gear 44 rotates, it drives the lead screw 45 fixed on its upper surface to rotate synchronously. The lifting bracket 46 threaded on the outer surface of the lead screw 45 will move up and down along its axis due to the rotation of the lead screw 45. The upper end of the lifting bracket 46 is fixedly connected to the top plate 47. When the lifting bracket 46 moves up and down, the top plate 47 moves up and down in the groove 11.

[0032] After the resistance ring is formed in the mold, the top plate 47 rises from the groove 11. Since its outer surface size is the same as the groove 11 and the inner wall size of the lower mold frame 2, it can push the formed material in the lower mold frame 2 upward to realize the unloading.

[0033] The guide rail 21 on the upper surface of the base plate 1 cooperates with the electric slider 22. The electric slider 22 drives the lower mold frame 2 to slide on the guide rail 21 through the connecting frame 23, which can realize the position adjustment of the lower mold frame 2.

[0034] The cooperation between the guide bar 24 and the sliding block 25 provides guidance for the movement of the connecting frame 23 and the lower mold frame 2, ensuring smooth movement and precise positioning.

[0035] After the electric push rod 31 is started, its output end pushes the pressure plate 3 to move downward. The upper mold 32, which is fixed on the lower surface of the pressure plate 3, moves downward and cooperates with the lower mold frame 2 to complete the pressing and forming of the resistance ring.

[0036] The feed pipe 33 is located on the upper surface of the pressure plate 3 and can convey raw materials into the mold before pressing.

[0037] The transmission chain between the motor 42 and the lead screw 45 is responsible for controlling the lifting and lowering timing of the top plate 47. Usually, after the molding is completed, the top plate 47 is lifted and unloaded by rotating the motor 42 in the forward direction. After unloading is completed, the motor 42 is reversed to make the top plate 47 fall back into the groove 11.

[0038] The movements of the electric slider 22 and the electric push rod 31 can coordinate to control the position of the mold and the pressing process. For example, the lower mold frame 2 can be moved to a designated position by the electric slider 22, and then the molding can be completed by the electric push rod 31.
