Description

Technical Field

[0001] This utility model belongs to the technical field of seat cushion foaming equipment, and in particular relates to a foaming equipment for producing high-strength tear-resistant polyurethane seat cushions. Background Technology

[0002] The automotive seat cushion foaming equipment is a key piece of equipment used to produce polyurethane foam seat cushions. The working principle of the automotive seat cushion foaming equipment is to instantly mix component A and component B under high pressure of 15-18MPa and then inject them into the mold for foaming and molding.

[0003] Existing foaming equipment for producing high-strength, tear-resistant polyurethane seat cushions requires manual spraying of polyurethane material into the mold, which often results in uneven spraying and makes the cushions prone to tearing. Therefore, we propose a foaming equipment for producing high-strength, tear-resistant polyurethane seat cushions. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a foaming device for producing high-strength, tear-resistant polyurethane seat cushions, thereby avoiding the problem of uneven spraying of polyurethane materials.

[0005] In view of this, the present invention provides a foaming device for producing high-strength tear-resistant polyurethane seat cushions, comprising a base, a fixed mold fixedly connected to the top of the base, a flipping mold hinged to the top edge of the fixed mold, a flipping push rod fixedly connected to the outer wall of the fixed mold, a lifting frame fixedly connected to the output end of the flipping push rod, a limit rod welded to the bottom end of the lifting frame, a limit groove formed at the connection between the base and the limit rod, flipping plates welded to the outer wall of the flipping mold being movably connected to both ends of the lifting frame, a flipping guide groove formed at the connection between the flipping plates and the lifting frame, and a bracket fixedly connected to the top edge of the base. A lifting cylinder is fixedly connected to the top, and a connecting seat is fixedly connected to the output end of the lifting cylinder. A spraying frame is welded to the bottom end of the connecting seat. A sliding motor is fixedly connected to the outer wall of the spraying frame. A sliding screw is fixedly connected to the output end of the sliding motor. A sliding seat is threadedly connected to the outer wall of the sliding screw. A slide rail fixedly connected to the outer wall of the spraying frame slides at the bottom end of the sliding seat. A reciprocating motor is fixedly connected to the outer wall of the sliding seat. A reciprocating screw is fixedly connected to the output end of the reciprocating motor. A spraying seat is threadedly connected to the outer wall of the reciprocating screw. A nozzle is fixedly connected to the bottom end of the spraying seat. One end of the nozzle is connected to a polyurethane cylinder through a pipe.

[0006] Based on the above structure, the sliding motor drives the sliding seat to slide along the outer wall of the slide rail via the sliding screw, so that the sliding seat slides and drives the nozzle to slide synchronously. At the same time, the reciprocating motor drives the spraying seat to slide back and forth along the bottom end of the sliding seat via the reciprocating screw. Then, the worker sprays the material in the polyurethane cylinder evenly onto the fixed mold through the nozzle, avoiding uneven spraying of polyurethane by manual spraying, which can easily cause the seat cushion to tear.

[0007] Preferably, two sets of limiting rods are provided, and the two sets of limiting rods are perpendicular to the lifting frame. In this embodiment, by providing two sets of limiting rods, it is convenient for the flip push rod to work and drive the limiting rod at the bottom of the lifting frame to slide along the groove of the limiting groove, which helps to improve the stability of the lifting frame movement.

[0008] Preferably, the flipping plate forms a flipping structure with the fixed mold through the lifting frame and the limiting groove. The flipping center of the flipping plate coincides with the hinge part of the fixed mold and the flipping mold. In this embodiment, the lifting frame slides through the flipping guide groove to drive the flipping plate to rotate. The rotation of the flipping plate drives the flipping mold and the fixed mold to perform a mold closing operation.

[0009] Preferably, the spraying frame is parallel to the fixed mold. In this embodiment, this facilitates the operation of the lifting cylinder to drive the spraying frame at the bottom of the connecting seat to slide vertically along the inner wall of the bracket.

[0010] Preferably, the central axis of the spraying frame coincides with the central axis of the fixed mold. In this embodiment, the material in the polyurethane cylinder is uniformly sprayed onto the fixed mold through a nozzle.

[0011] Preferably, the sliding screw is perpendicular to the reciprocating screw, which in this embodiment facilitates the uniform spraying of polyurethane.

[0012] Preferably, the sliding seat forms a sliding structure with the slide rail via a sliding screw, and the spraying seat forms a reciprocating structure with the spraying frame via a reciprocating screw. In this embodiment, the sliding motor drives the sliding seat to slide along the outer wall of the slide rail via the sliding screw, so that the sliding seat drives the nozzle to slide synchronously. At the same time, the reciprocating motor drives the spraying seat to slide back and forth along the bottom end of the sliding seat via the reciprocating screw, thereby realizing precise control of the nozzle's movement trajectory.

[0013] The beneficial effects of this utility model are:

[0014] 1. This foaming equipment for producing high-strength tear-resistant polyurethane seat cushions uses a sliding screw and a reciprocating screw. The sliding motor drives the sliding seat to slide along the outer wall of the slide rail via the sliding screw, causing the nozzle to slide synchronously. At the same time, the reciprocating motor drives the spraying seat to slide back and forth along the bottom end of the sliding seat via the reciprocating screw. Then, the operator sprays the polyurethane material from the barrel evenly onto the fixed mold through the nozzle, avoiding uneven spraying of polyurethane by manual spraying, which can easily cause the seat cushion to tear.

[0015] 2. This foaming equipment for producing high-strength tear-resistant polyurethane seat cushions, by setting a flip plate, after the lifting cylinder is reset, the flip push rod works to drive the limit rod at the bottom of the lifting frame to slide along the groove of the limit groove, so that the lifting frame slides through the flip guide groove to drive the flip plate to rotate, and the rotation of the flip plate drives the flip mold and the fixed mold to perform mold closing operation.

One end of the nozzle 20 is connected to a polyurethane cylinder through a pipe.

[0025] Based on the above structure, the sliding motor 13 drives the sliding seat 15 to slide along the outer wall of the slide rail 16 via the sliding screw 14, so that the sliding seat 15 drives the nozzle 20 to slide synchronously. At the same time, the reciprocating motor 17 drives the spraying seat 19 to slide back and forth along the bottom end of the sliding seat 15 via the reciprocating screw 18. Then, the operator sprays the material in the polyurethane cylinder evenly onto the fixed mold 101 through the nozzle 20, avoiding uneven manual spraying of polyurethane, which could easily cause the seat cushion to tear.

[0026] In one embodiment, two sets of limiting rods 5 are provided, and the two sets of limiting rods 5 are perpendicular to the lifting frame 4.

[0027] In this embodiment, by setting two sets of limiting rods 5, it is convenient for the flipping push rod 3 to work and drive the limiting rod 5 at the bottom of the lifting frame 4 to slide along the groove of the limiting groove 6, which helps to improve the stability of the movement of the lifting frame 4.

[0028] In one embodiment, the flipping plate 7 forms a flipping structure with the fixed mold 101 through the lifting frame 4 and the limiting groove 6, and the flipping center of the flipping plate 7 coincides with the hinge part of the fixed mold 101 and the flipping mold 2.

[0029] In this embodiment, the lifting frame 4 slides through the flipping guide groove 8 to drive the flipping plate 7 to rotate, and the rotation of the flipping plate 7 drives the flipping mold 2 and the fixed mold 101 to perform a mold closing operation.

[0030] In one embodiment, the spraying frame 12 is parallel to the fixed mold 101.

[0031] In this embodiment, it is beneficial for the lifting cylinder 10 to work and drive the spraying frame 12 at the bottom of the connecting seat 11 to slide vertically along the inner wall of the bracket 9.

[0032] In one embodiment, the central axis of the spraying frame 12 coincides with the central axis of the fixed mold 101.

[0033] In this embodiment, the material in the polyurethane cylinder is uniformly sprayed onto the fixed mold 101 through the nozzle 20.

[0038] In this embodiment, the foaming equipment for producing high-strength tear-resistant polyurethane seat cushions operates as follows: First, the lifting cylinder 10 drives the spraying frame 12 at the bottom of the connecting seat 11 to slide vertically along the inner wall of the support 9. The sliding of the spraying frame 12 causes the nozzle 20 to move above the fixed mold 101. Then, the sliding motor 13 drives the sliding seat 15 to slide along the outer wall of the slide rail 16 via the sliding screw 14, causing the sliding seat 15 to slide synchronously with the nozzle 20. At the same time, the reciprocating motor 17 drives the spraying seat 19 to slide back and forth along the bottom of the sliding seat 15 via the reciprocating screw 18. Then, the operator sprays the material in the polyurethane cylinder evenly onto the fixed mold 101 through the nozzle 20, avoiding uneven manual spraying of polyurethane, which could cause the seat cushion to tear easily.

[0039] Next, after the lifting cylinder 10 is reset, the flipping push rod 3 drives the limiting rod 5 at the bottom of the lifting frame 4 to slide along the groove of the limiting groove 6, so that the lifting frame 4 slides through the flipping guide groove 8 to drive the flipping plate 7 to rotate. The rotation of the flipping plate 7 drives the flipping mold 2 and the fixed mold 101 to perform the mold closing operation.

[0040] Finally, the polyurethane material is foamed and shaped in the cavities inside the flipping mold 2 and the fixed mold 101.
