Description

Technical Field

[0001] This utility model relates to the technical field of mold support mechanisms, specifically an internal support mechanism for a rubber drainage pipe mold. Background Technology

[0002] Because of its good physiological inertness, UV resistance, ozone resistance, high and low temperature resistance, high transparency, and strong resilience, rubber hoses are often produced using molds to assist in the production process.

[0003] In traditional molds, heated rubber is often introduced into the mold cavity, causing the rubber to form a rubber tube under the action of the mold. The inner cavity of the rubber tube is often hollow, so the inner cavity of the mold is also hollow. Traditional molds lack support for the inner wall of the mold, causing the inner wall of the mold to deform under pressure when the rubber is injected into the mold. This leads to abnormalities in the production of the rubber tube, changes in the mold, and thus affects the quality of the finished rubber tube. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an internal support mechanism for a rubber drainage pipe mold, which has the advantages of supporting the internal cavity and being easy to use, thus solving the problems mentioned in the background art.

[0006] As a preferred technical solution of this utility model: the output shaft of the electric push rod is connected to the outer wall of the moving block and the slider respectively, and the inner wall shape of the moving block and the slider matches the outer wall shape of the support shaft.

[0007] As a preferred technical solution of this utility model: the outer wall of the movable block is rotatably connected to a support plate, the limiting seat passes through the inner cavity of the auxiliary frame, and the outer wall of the limiting seat is slidably connected to the inner cavity of the auxiliary frame.

[0008] As a preferred technical solution of this utility model: there are two auxiliary frames, and the two auxiliary frames are respectively installed at both ends of the outer wall of the support shaft.

[0009] As a preferred technical solution of this utility model: the outer wall diameter of the outer cylinder is equal to the inner wall diameter of the connecting seat, and the outer wall of the end of the threaded cylinder away from the first screw is threadedly connected to the inner wall of the fixed screw.

Under the action of the electric push rod 11, the slider 9 and movable block 7 are driven, so that the movable block 7 and slider 9 move along the outer wall of the support shaft 6. When the movable block 7 and slider 9 move, they can drive the support plate 8 and the arc plate 10, so that the arc plate 10 moves outward, thereby supporting the inner cylinder 4 under the action of the arc plate 10, and playing a supporting role on the inner wall of the inner cylinder 4.

[0023] In a preferred embodiment, the output shaft of the electric push rod 11 is connected to the outer wall of the moving block 7 and the slider 9, respectively, and the inner wall shape of the moving block 7 and the slider 9 matches the outer wall shape of the support shaft 6.

[0024] In the above structure, the support shaft 6 provided in the inner cavity of the connecting seat 3, and the moving block 7 and slider 9 provided on the outer wall of the support shaft 6, can drive the support plate 8 when the moving block 7 and slider 9 move, and under the action of the support plate 8, the arc plate 10 is pushed upward, thereby supporting the inner wall of the inner cylinder 4 under the action of the arc plate 10, so that the inner cylinder 4 has better stability when in use.

[0025] In a preferred embodiment: the outer wall of the movable block 7 is rotatably connected to the support plate 8, the limiting seat 13 passes through the inner cavity of the auxiliary frame 12, and the outer wall of the limiting seat 13 is slidably connected to the inner cavity of the auxiliary frame 12.

[0026] In the above structure, the limiting seat 13 provided on the outer wall of the arc plate 10 can support the arc plate 10 when the moving block 7 and the slider 9 move. During the movement of the arc plate 10, the limiting seat 13 moves along the inner wall of the auxiliary frame 12, which can restrict the arc plate 10 and enable the arc plate 10 to better support the inner wall of the inner cylinder 4.

[0027] In a preferred embodiment, there are two auxiliary frames 12, and the two auxiliary frames 12 are respectively installed at both ends of the outer wall of the support shaft 6.

[0028] In the above structure, the auxiliary frames 12 provided at both ends of the outer wall of the support shaft 6 can restrict the arc plate 10 under the action of the auxiliary frames 12. The limiting seats 13 at both ends of the arc plate 10 will move along the inner wall of the auxiliary frames 12, so that the outer wall of the arc plate 10 contacts the inner wall of the inner cylinder 4, thereby supporting the inner wall of the inner cylinder 4.

[0029] In a preferred embodiment: the outer wall diameter of the outer cylinder 2 is equal to the inner wall diameter of the connecting seat 3, and the outer wall of the threaded cylinder 15 at the end away from the first screw 16 is threadedly connected to the inner wall of the fixing screw 17.

[0030] In the above structure, by setting a first screw 16 and a fixed screw 17 on the outer wall of the connecting seat 3 and the movable seat 5, the first screw 16 and the fixed screw 17 can be pulled by rotating the threaded cylinder 15, so that the outer wall of the connecting seat 3 and the movable seat 5 is attached to the outer wall of the outer cylinder 2, thereby sealing the space between the outer cylinder 2 and the inner cylinder 4.

[0031] In a preferred embodiment: the support shaft 6 is rotatably connected to the inner cavity of the movable seat 5, and limit seats 13 are installed at both ends of the outer wall of the arc plate 10.

[0032] In the above structure, the support shaft 6 provided in the inner cavity of the connecting seat 3, when the moving block 7 and slider 9 on the outer wall of the support shaft 6 move, can support the arc plate 10, so that the outer wall of the arc plate 10 can support the inner wall of the inner cylinder 4, so that when rubber is poured into the inner cavity of the outer cylinder 2 and the inner cylinder 4, the inner cylinder 4 can maintain a relatively stable state, thereby better producing rubber tubes.

[0033] Working principle: During use, the connecting seat 3 passes through the inner cavity of the outer cylinder 2, and the two ends of the threaded cylinder 15 are respectively connected to the outer walls of the first screw 16 and the fixed screw 17. Then, by rotating the threaded cylinder 15, the connecting seat 3 and the movable seat 5 can move closer to each other under the traction of the threaded cylinder 15, thereby sealing the inner cavity of the outer cylinder 2. At this time, a closed space can be formed under the action of the inner cylinder 4 and the outer cylinder 2. By activating the electric push rod 11, the connecting seat 3 and the movable seat 5 are respectively connected to the outer wall of the fixed screw 17. The moving block 7 and the slider 9 are driven to move along the outer wall of the support shaft 6, bringing them closer together. When the moving block 7 and the slider 9 are close together, they can continue to drive the support plate 8, thereby pushing the outer wall of the arc plate 10 upward and supporting the inner wall of the inner cylinder 4. Then, rubber is injected into the space between the outer walls of the inner cylinder 4 and the outer cylinder 2 through the injection port 18 on the outer wall of the connecting seat 3 and the moving seat 5. At this time, rubber can be poured into the space between the inner cylinder 4 and the outer cylinder 2 to form a rubber tube.
