Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring production technology, specifically a shaping device for rubber sealing ring production. Background Technology

[0002] A rubber seal is an annular cover composed of one or more parts. It is usually fixed on one of the bearing rings or washers and contacts or forms a narrow labyrinth gap with another ring or washer to prevent lubricating oil leakage and foreign matter intrusion. In the production process of rubber seals, molds are needed to shape the rubber seals, and shaping devices for rubber seal production are required.

[0003] The existing technology has the following problems:

[0004] Traditional rubber seals are produced with complex mold assembly and disassembly. The mold is difficult to position, disassemble, and replace. In addition, the mold is usually cooled naturally after injection molding, which is slow and does not improve the cooling effect. It is also inconvenient to use water to absorb and utilize the heat during cooling. Utility Model Content

[0005] The purpose of this invention is to provide a shaping device for producing rubber sealing rings, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shaping device for producing rubber sealing rings, comprising a support plate and four fixed frames fixedly installed on the top of the support plate. The support plate is provided with a shaping component and a disassembly component. The shaping component includes a movable plate slidably installed inside the four fixed frames. A lower mold is provided at the top of the support plate, and an upper mold is provided at the bottom of the movable plate. The upper mold corresponds to the lower mold. A heat dissipation groove is provided inside the lower mold, and multiple guide plates are fixedly connected inside the heat dissipation groove. The disassembly component includes four positioning frames fixedly installed inside the support plate and the movable plate. A positioning frame is provided on both sides of the lower mold and the upper mold. Two sliding rods slide through the inner side of each positioning frame. Two fixed slots are provided on both sides of the lower mold and the upper mold. One end of each sliding rod extends into a fixed slot. A movable slot is provided on the inner side of each positioning frame.

[0007] By moving the upper mold downwards to engage with the lower mold, the rubber sealing ring can be easily injection molded and shaped. Water is introduced into the heat dissipation groove from the front of the lower mold and guided upwards by the guide plate, allowing the water to absorb the heat from the lower mold. The heated water is then discharged from the rear of the lower mold, which can be used to dissipate heat and cool the injection-molded rubber sealing ring. At the same time, the heat can be absorbed and utilized. By pulling the slide rod outwards, the lower mold and the upper mold can be quickly disassembled. By placing the upper or lower mold inside the positioning frame, the upper and lower molds can be easily positioned. The inclined surface at one end of the slide rod allows the upper or lower mold to push the slide rod outwards and then push the slide rod inwards automatically, which can quickly install the lower mold and the upper mold and facilitate the disassembly and assembly of the lower mold and the upper mold.

[0008] Preferably, a fixed plate is fixedly installed on the top of each of the four fixed frames, and a telescopic rod is fixedly connected to the bottom of the fixed plate. The output end of the telescopic rod is fixedly installed to the movable plate. The fixed plate can support and fix the telescopic rod, allowing the telescopic rod to drive the movable plate to move up and down.

[0009] Preferably, two sliders are fixedly installed on each side of the movable plate, and each slider is located inside a fixed frame and slidably installed with the fixed frame. Moving the movable plate up and down allows the sliders to slide along the fixed frame, preventing the movable plate from tilting during vertical movement.

[0010] Preferably, the upper and lower molds have injection holes on their inner sides, and the top of the movable plate is fixedly equipped with an injection port, which communicates with the injection holes. Melted rubber can be introduced into the injection tank through the injection port, and the injection tank is used to transport the rubber between the upper and lower molds for shaping.

[0011] Preferably, a movable rod is fixedly installed between every two sliding rods, each movable rod is located inside a movable groove and slidably installed with the groove, and two thrust springs are fixedly connected between each movable rod and the movable groove. The movable plate allows the thrust springs to easily push the sliding rods inward.

[0012] Preferably, each positioning frame has a guide groove on its inner side, and the multiple guide grooves correspond to the lower mold and the upper mold respectively. The front and rear ends of the lower mold are fixedly installed with connecting pipes, and both connecting pipes are connected to the heat dissipation groove. The guide grooves can guide the upper mold and the lower mold, so that the lower mold on one side of the upper mold can be inserted into the positioning frame for positioning and fixation. The connecting pipes can introduce water into the heat dissipation groove and simultaneously drain water from the heat dissipation groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By employing a combination of a lower mold, an upper mold, a positioning frame, a sliding rod, and a guide plate, the upper mold moves downwards to engage with the lower mold, facilitating the shaping and production of the rubber sealing ring. Water is introduced from the front of the lower mold into the heat dissipation groove, and the guide plate directs the water upwards, allowing the water to absorb heat from the lower mold. The heated water is then discharged from the rear of the lower mold, facilitating the cooling and heat dissipation of the injection-molded rubber sealing ring. Simultaneously, heat absorption and utilization are achieved. By pulling the sliding rod outwards, it separates from the fixing groove, allowing for quick disassembly of the lower and upper molds. Placing either the upper or lower mold inside the positioning frame facilitates quick installation and disassembly of the molds, as well as convenient positioning. Attached Figure Description

The lower mold 10 has a heat dissipation groove 15 inside, and multiple guide plates 16 are fixedly connected inside the heat dissipation groove 15. The disassembly component includes four positioning frames 8 fixedly installed inside the support plate 1 and the movable plate 4. A positioning frame 8 is provided on both sides of the lower mold 10 and the upper mold 11. Two sliding rods 9 slide through the inner side of each positioning frame 8. Two fixing grooves 17 are opened on both sides of the lower mold 10 and the upper mold 11. One end of each sliding rod 9 extends into a fixing groove 17. A movable groove 13 is opened on the inner side of each positioning frame 8.

[0023] A fixed plate 3 is fixedly installed on the top of the four fixed frames 2, and a telescopic rod 5 is fixedly connected to the bottom of the fixed plate 3. The output end of the telescopic rod 5 is fixedly installed with the movable plate 4.

[0024] Two sliders 6 are fixedly installed on both sides of the movable plate 4. Each slider 6 is located inside a fixed frame 2 and is slidably installed with the fixed frame 2.

[0025] Injection holes 12 are provided on the inner sides of the upper mold 11 and the lower mold 10. An injection port 7 is fixedly installed on the top of the movable plate 4, and the injection port 7 is connected to the injection hole 12.

[0026] A movable rod 14 is fixedly installed between every two sliding rods 9. Each movable rod 14 is located inside a movable groove 13 and is slidably installed with the movable groove 13. Two thrust springs 19 are fixedly connected to each movable rod 14 and the movable groove 13.
