Description

Technical Field

[0001] The utility model belongs to the technical field of the structure of a molding machine, and particularly relates to a polytetrafluoroethylene glass fiber substrate molding machine. Background Art

[0002] A glass fiber substrate molding machine is a device specifically used for producing glass fiber reinforced plastic products. Through the action of heating and pressure, glass fibers and resins are fully fused to form a strong and durable composite material. Therefore, it can be seen that the existing molding machines basically meet people's usage requirements, but there are still the following problems.

[0003] When an operator uses a glass fiber substrate molding machine, the operator installs a molding die in the glass fiber substrate molding machine. When installing the molding die, the operator first installs the lower die at the lower end inside the glass fiber substrate molding machine, and then the operator installs the upper die at the upper end of the glass fiber substrate molding machine. When the operator installs the upper die, the operator may need to first hold up the upper die and make the upper die fit with the mounting plate, and then the operator installs bolts one by one into the upper die to install the upper die and the mounting together. However, since the upper die is generally heavy, it is rather laborious for the operator to hold up the upper die for a long time. For this reason, we propose a polytetrafluoroethylene glass fiber substrate molding machine. Summary of the Utility Model

[0004] The utility model provides a polytetrafluoroethylene glass fiber substrate molding machine. By placing the upper die between two push plates, the push plates support the die. When the operator installs the upper die on the mounting plate, it is no longer necessary for the operator to always hold up the upper die, improving the convenience of the operator in installing the upper die.

[0005] To achieve the above object, the utility model provides the following technical solution: A polytetrafluoroethylene glass fiber substrate molding machine, including a molding machine main body and a mounting plate. The mounting plate is installed in the middle of the molding machine main body. A collar is sleeved on the surface of the molding machine main body on the side where the molding machine main body is connected to the mounting plate, and connecting rods are rotatably connected to both sides of the collar. The ends of the connecting rods are rotatably connected to rotating rods, and upper baffles are fixed to the ends of the rotating rods. Sliding grooves are sleeved on the surfaces of the upper baffles, and sliders fixed to the upper baffles penetrate through the middle of the sliding grooves. Lower baffles are fixed to the ends of the sliders. Fixed blocks are fixed to the ends of the lower baffles, and spring grooves are slidably connected to the ends of the fixed blocks. Push plates are elastically connected to the surfaces of the spring grooves.

[0006] Further, rotating blocks are fixed to the sides of the spring grooves that are in contact with the fixed blocks, and third rotating grooves opened on the fixed blocks are sleeved on the surfaces of the rotating blocks.

[0007] Further, traction plates are symmetrically and fixedly arranged on both sides of the spring groove, and traction blocks are fixedly arranged on the sides of the traction plates that are in mutual contact with the fixed blocks. Traction grooves are formed in the fixed blocks and sleeved on the surfaces of the traction blocks.

[0008] Further, a resisting block and a first spring are respectively arranged inside the spring groove. The two end parts of the first spring are respectively abutted between the surface of the resisting block and the inner wall of the spring groove, and push plates are fixedly arranged on the surfaces of the resisting blocks.

[0009] Further, second rotating grooves and first rotating grooves fixed on a rotating sleeve and a collar are respectively sleeved on the two end parts of the connecting rod. Second rotating shafts and first rotating shafts fixed on the inner walls of the second rotating groove and the collar respectively penetrate through one side of the middle parts of the two end parts of the connecting rod inserted into the second rotating groove and the first rotating groove.

[0010] Further, avoidance grooves formed in the mounting plate are communicated with one side of the inner wall of the sliding groove. Slide bars penetrating through the sliding blocks are fixedly arranged on the inner walls of the avoidance grooves and the sliding groove, and second springs respectively abutted between the inner wall of the avoidance groove and the surface of the sliding block are wound on the surfaces of the slide bars.

[0011] Further, a connecting plate is fixedly arranged in the middle of the collar, a handle is fixedly arranged in the middle of the connecting plate, and a plurality of groups of wavy grooves are formed on the surface of the handle.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. The PTFE glass fiber substrate forming machine is provided with an upper baffle, a sliding block, a lower baffle, a spring groove and a push plate. By an operator pulling the spring groove, the spring groove drives the sliding block to slide in the sliding groove through the lower baffle, so that the spring groove drives the push plate to move, and the gap between the two push plates is adjusted. Then, the operator places the glass fiber substrate forming die between the two push plates, and the push plates support the glass fiber substrate forming die. When the operator is installing the upper die of the glass fiber substrate forming die, it is no longer necessary for the operator to continuously push the upper die of the glass fiber substrate forming die, improving the convenience of the operator installing the upper die.

Detailed implementation mode

[0026] In order to further understand the content, features and effects of the present utility model, the following embodiments are cited and described in detail in conjunction with the accompanying drawings. Embodiment

[0027] Please refer to Figure 1 - Figure 9, a polytetrafluoroethylene fiberglass substrate molding machine, including a molding machine main body 1 and a mounting plate 2. The mounting plate 2 is installed in the middle of the molding machine main body 1. A collar 9 is sleeved on the surface of the molding machine main body 1 on the side where the molding machine main body 1 and the mounting plate 2 are connected to each other. Connecting rods 4 are rotatably connected to both sides of the collar 9. The ends of the connecting rods 4 are rotatably connected to rotating rods 21. Second rotating grooves 29 and first rotating grooves 8 welded to the rotating sleeves 20 and the collar 9 are respectively sleeved on both side ends of the connecting rods 4. Second rotating shafts 10 and first rotating shafts 7 welded to the inner walls of the second rotating grooves 29 and the collar 9 respectively penetrate through one side of the middle parts of the second rotating grooves 29 and the first rotating grooves 8 where the two side ends of the connecting rods 4 are inserted. Upper baffles 19 are welded to the ends of the rotating rods 21. Chute grooves 5 are sleeved on the surfaces of the upper baffles 19. Sliders 11 welded to the upper baffles 19 penetrate through the middle parts of the chute grooves 5. Lower baffles 12 are welded to the ends of the sliders 11. Fixing blocks 24 are welded to the ends of the lower baffles 12. Spring grooves 15 are slidably connected to the ends of the fixing blocks 24. Push plates 13 are elastically connected to the surfaces of the spring grooves 15. A resisting block 16 and a first spring 14 are respectively arranged inside the spring grooves 15. The two side ends of the first spring 14 are respectively abutted between the surface of the resisting block 16 and the inner wall of the spring groove 15. Push plates 13 are welded to the surfaces of the resisting blocks 16. When the operator needs to adjust the gap between the two push plates 13, the operator first rotates the collar 9. When the collar 9 rotates, the collar 9 drives the first rotating shaft 7 to move through the first rotating groove 8. When the first rotating shaft 7 moves, the first rotating shaft 7 pulls the connecting rod 4. And when the first rotating shaft 7 pulls the connecting rod 4 to move, the circular through hole opened on one side of the connecting rod 4 penetrated by the first rotating shaft 7 rotates on the surface of the first rotating shaft 7, so that the connecting rod 4 slides in the first rotating groove 8. When the collar 9 drives the connecting rod 4 to rotate, the angles of the collar 9 and the connecting rod 4 change. And when the connecting rod 4 moves, the circular through hole opened on one side of the end of the connecting rod 4 penetrated by the second rotating shaft 10 pulls the second rotating shaft 10 to move. The second rotating shaft 10 drives the rotating sleeve 20 to move through the second rotating groove 29. When the rotating sleeve 20 moves, the rotating sleeve 20 drives the rotating rod 21 to move. The rotating rod 21 pulls the upper baffle 19 to move. The upper baffle 19 drives the lower baffle 12 to move through the slider 11, so that the upper baffle 19, the slider 11 and the lower baffle 12 slide in the chute groove 5. And when the lower baffle 12 moves, the lower baffle 12 drives the spring groove 15 to move through the fixing block 24. The spring groove 15 drives the push plate 13 to move, which is convenient for the operator to adjust the gap between the two push plates 13 simultaneously;

[0028] After the operator finishes adjusting the position of the push plate 13, the operator holds the upper mold and places the upper mold on the connecting plate 3, so that the connecting plate 3 supports the upper mold, and it is no longer necessary for the operator to keep pushing the upper mold of the fiberglass substrate molding die, improving the convenience for the operator to install the upper mold;

[0029] And when the operator pulls the push plate 13, the push plate 13 drives the resistance block 16 to slide in the spring groove 15, and the resistance block 16 squeezes the first spring 14, causing the first spring 14 to undergo elastic deformation. The first spring 14 avoids the resistance block 16, allowing the push plate 13 to slide on the surface of the spring groove 15, making it convenient for the operator to adjust the position of the push plate 13, and to place upper molds of different thicknesses on the push plate 13, thereby increasing the operator's range of use.

[0030] In other embodiments, a rotating block 22 is welded on one side of the spring slot 15 and the fixed block 24 that are fitted together, and a third rotating slot 23 is sleeved on the surface of the rotating block 22 and is provided on the fixed block 24. When the operator needs to adjust the position of the spring slot 15 and the push plate 13, the operator first pulls the spring slot 15, and the spring slot 15 drives the rotating block 22 to slide in the third rotating slot 23, so that the spring slot 15 moves at the end of the fixed block 24, and the spring slot 15 drives the push plate 13 to move at the end of the fixed block 24, so that it is convenient to support upper molds of different sizes, thereby improving the operator's range of use.

[0031] In other embodiments, traction plates 25 are symmetrically welded on both sides of the spring slot 15, and traction blocks 26 are welded on the side where the traction plate 25 and the fixed block 24 are in contact with each other. The surface of the traction block 26 is sleeved with a traction groove 27 opened on the fixed block 24. When the spring slot 15 moves, the spring slot 15 drives the traction plate 25 to move, and when the traction plate 25 moves, the traction plate 25 drives the traction block 26 to slide in the traction groove 27, so that the traction plate 25, the traction block 26 and the traction groove 27 are convenient for traction of the spring slot 15 at the end of the fixed block 24.

[0032] In other embodiments, one side of the inner wall of the sliding groove 5 is communicated with an avoidance groove 18 opened on the mounting plate 2. Slide rods 6 penetrating through the slider 11 are welded to both the inner wall of the avoidance groove 18 and the inner wall of the sliding groove 5. Second springs 17 respectively abutting between the inner wall of the avoidance groove 18 and the surface of the slider 11 are wound around the surfaces of the slide rods 6. When the slider 11 slides in the sliding groove 5, a circular through hole opened in the middle of the slider 11 slides on the surface of the slide rod 6 provided as a cylinder. By sliding the slider 11 on the surface of the slide rod 6, the slide rod 6 pulls the moving direction of the slider 11, improving the stability of the slider 11 moving in the sliding groove 5. Moreover, when the slider 11 moves, the slider 11 presses the second spring 17, and the second spring 17 yields to the slider 11. After being pressed, the second spring 17 moves into the avoidance groove 18, and the avoidance groove 18 accommodates the contracted second spring 17. And when the slider 11 is no longer pushed by the operator, after the slider 11 no longer presses the second spring 17, the elastic deformation of the second spring 17 is restored, and the second spring 17 pushes the slider 11 to move, enabling the slider 11 to drive the spring groove 15 to move through the lower baffle 12, and the spring groove 15 drives the push plate 13 to move, facilitating the automatic mutual approach of the push plates 13.

[0033] In other embodiments, a connecting plate 3 is welded to the middle of the collar 9, and a handle 28 is welded to the middle of the connecting plate 3. A plurality of groups of wavy grooves are opened on the surface of the handle 28. When the operator pushes and rotates the collar 9, the operator holds the hand on the surface of the handle 28. After the operator holds the hand on the surface of the handle 28, the hand of the operator fits with a plurality of groups of wavy grooves opened on the surface of the handle 28, so that the plurality of groups of wavy grooves opened on the surface of the handle 28 increase the friction force between the hand of the operator and the surface of the handle 28, increasing the stability of the operator pulling the handle 28. Subsequently, the operator pulls the handle 28, and the handle 28 drives the collar 9 to rotate through the connecting plate 3, improving the convenience of the operator rotating the collar 9.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made therein without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
