Description

Technical Field

[0001] The utility model relates to the technical field of molds, and specifically relates to a mold for producing a molded rubber elbow. Background Technique

[0002] When processing a tetrafluoroethylene pipe elbow, it is usually necessary to insert a rubber elbow lining inside it, and then use a mold to press the port of the rubber elbow flat on the flange of the tetrafluoroethylene pipe elbow. When pressing the port of the rubber elbow flat, two kinds of molds are needed. One is a frustum-shaped mold, through which the edge of the port of the rubber elbow is extruded to turn outwards. The other is a flat mold, through which the turned-out port of the rubber elbow is pressed flat on the flange of the tetrafluoroethylene pipe elbow. When workers use the existing molds, they need to continuously pick up and switch different molds, and then align the molds to the port position of the rubber elbow. The operation is cumbersome. Moreover, when using the existing molds, workers need to hold the long handle of the mold and lift the mold to the position of the rubber elbow port. Most of the existing molds are made of iron, and the weight of the mold is relatively heavy. Lifting the mold frequently greatly increases the working intensity of the workers.

[0003] Therefore, we design a mold for producing a molded rubber elbow here. Content of the Utility Model

[0004] The purpose of the utility model is to provide a mold for producing a molded rubber elbow for the deficiencies of the existing technology, so as to solve the problems raised in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A mold for producing a molded rubber elbow, including a long column and a short column. The long column and the short column are arranged opposite to each other and are both vertically installed on the base. On one side of the long column facing the short column, a rotating mounting seat is installed. A sector plate is rotatably mounted on the rotating mounting seat. On the front surface of the sector plate, a first mold is arranged. On the back surface of the first mold, a first sliding rod is installed. The first sliding rod penetrates through the sector plate and can slide in the through hole. The end of the first sliding rod is installed with a first bottom plate.

A second spring is sleeved on the second sliding rod, and the second spring abuts between the sector plate and the second bottom plate;

[0007] The distance from the short column to the rotating mounting seat is greater than the distance from the rotating mounting seat to the arc edge of the sector plate. On one side of the short column facing the long column, two symmetrically arranged limiting blocks are installed. The distance between the two limiting blocks is equal to the thickness of the sector plate, and the sector plate is clamped between the two limiting blocks.

[0008] Preferably, a pull rod is installed on the arc-shaped edge of the sector plate, and a groove for the pull rod to pass through is formed at the top of the short column.

Detailed implementation mode

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 - 3 , in this implementation scheme: A mold for producing a molded rubber elbow includes a long vertical column 1 and a short vertical column 2. Please refer to Figure 1 , the long vertical column 1 and the short vertical column 2 are arranged oppositely and are both vertically installed on the base 19. On one side of the long vertical column 1 facing the short vertical column 2, a rotating mounting seat 3 is installed. A sector plate 4 is rotatably mounted on the rotating mounting seat 3. On the front surface of the sector plate 4, a first mold 5 is provided. On the back surface of the first mold 5, a first sliding rod 6 is installed. The first sliding rod 6 penetrates the sector plate 4 and can slide in the through hole. The end of the first sliding rod 6 is installed with a first bottom plate 7. A first spring 8 is sleeved on the first sliding rod 6. The first spring 8 abuts between the sector plate 4 and the first bottom plate 7. When an external force pushes the first bottom plate 7 forward, the first bottom plate 7 can push the first mold 5 forward through the first sliding rod 6, and the first spring 8 will be compressed by force. When the external force disappears, under the elastic force of the first spring 8, the first mold 5 and the first bottom plate 7 will return to their original positions.

[0020] On the front surface of the sector plate 4, a second mold 9 is also provided. On the back surface of the second mold 9, a second sliding rod 10 is installed. The second sliding rod 10 penetrates the sector plate 4 and can slide in the through hole. The end of the second sliding rod 10 is installed with a second bottom plate 11. A second spring 12 is sleeved on the second sliding rod 10. The second spring 12 abuts between the sector plate 4 and the second bottom plate 11. When an external force pushes the second bottom plate 11 forward, the second bottom plate 11 can push the second mold 9 forward through the second sliding rod 10, and the second spring 12 will be compressed by force. When the external force disappears, under the elastic force of the second spring 12, the second mold 9 and the second bottom plate 11 will return to their original positions.

[0021] The distance from the short vertical column 2 to the rotating mounting seat 3 is greater than the distance from the rotating mounting seat 3 to the arc edge of the sector plate 4. On one side of the short vertical column 2 facing the long vertical column 1, two symmetrically arranged limit blocks 13 are installed. The distance between the two limit blocks 13 is equal to the thickness of the sector plate 4. The sector plate 4 is sandwiched between the two limit blocks 13. The limit blocks 13 can play a role in protecting the sector plate 4. When an external force pushes the sector plate 4, the limit blocks 13 can abut in front of the unfixed side of the sector plate 4, thereby preventing the sector plate 4 from being bent or broken.

[0022] On one side of the long vertical column 1 facing the short vertical column 2, the first iron block 15 and the second iron block 16 are installed in an up-and-down distribution. The rotating mounting seat 3 is located between these two iron blocks. The upper and lower straight edges of the sector plate 4 are respectively installed with the first magnet 17 and the second magnet 18. The first magnet 17 can be attracted to the first iron block 15, and the second magnet 18 can be attracted to the second iron block 16. The function of the cooperation between the magnet and the iron block is to fix the rotation position of the sector plate 4. Initially, the first magnet 17 is attracted to the first iron block 15. After the sector plate 4 is rotated 90 degrees, the first magnet 17 will be separated from the first iron block 15, and at the same time, the second magnet 18 will be attracted to the second iron block 16. The front of the first mold 5 is a frustum of a cone, and the front of the second mold 9 is a circular plane. The distance from the axis of the first mold 5 to the rotation axis of the sector plate 4 is equal to the distance from the axis of the second mold 9 to the rotation axis of the sector plate 4. When the second mold 9 rotates 90 degrees around the rotation axis of the sector plate 4, its axis will coincide with the axis of the first mold 5. A pull rod 14 is installed on the arc edge of the sector plate 4, and a groove for the pull rod 14 to pass through is opened at the top of the short vertical column 2. The function of the pull rod 14 is to facilitate the worker to rotate the sector plate 4.

[0023] Please refer to Figure 2 and Figure 3 , a first workbench 20 and a second workbench 22 are further installed on the base 19. The first workbench 20 is located behind the sector plate 4, and a hydraulic cylinder 21 is installed on the first workbench 20. Initially, the output rod of the hydraulic cylinder 21 is directly opposite to the first bottom plate 7. The second workbench 22 is located in front of the sector plate 4, and a cushion block 23 and a clamping plate 24 are installed on the second workbench 22. The function of the cushion block 23 and the clamping plate 24 is to place the elbow body 25 and limit the position of the elbow body 25.

[0024] Working principle and usage process of the present utility model: When using the mold for producing molded rubber elbows, place the elbow body 25 with the rubber elbow lining inserted on the cushion block 23, and use the clamping plate 24 to clamp the flange of the elbow body 25. Heat the front port of the rubber elbow with a blowtorch to soften it. Rotate the sector plate 4 so that the first magnet 17 attracts to the first iron block 15. Then start the hydraulic cylinder 21. The output rod of the hydraulic cylinder 21 pushes the first bottom plate 7 forward. The first bottom plate 7 pushes the first mold 5 forward horizontally through the first sliding rod 6. Through the extrusion of the first mold 5, the edge of the front port of the rubber elbow turns outwards. After controlling the output rod of the hydraulic cylinder 21 to reset, under the elastic force of the first spring 8, the first mold 5 and the first bottom plate 7 will return to their original positions. Then rotate the sector plate 4 so that the second magnet 18 attracts to the second iron block 16. Start the hydraulic cylinder 21 again. The output rod of the hydraulic cylinder 21 pushes the second bottom plate 11 forward. The second bottom plate 11 pushes the second mold 9 forward horizontally through the second sliding rod 10. Through the extrusion of the second mold 9, the front port of the rubber elbow is flattened on the flange of the elbow body 25. After controlling the output rod of the hydraulic cylinder 21 to reset, under the elastic force of the second spring 12, the second mold 9 and the second bottom plate 11 will return to their original positions, and the molding of the rubber elbow is completed.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
