Description

Technical Field

[0001] This utility model relates to the field of foaming production lines, specifically to a turntable structure for foaming production of automotive interior parts. Background Technology

[0002] Foaming platforms are specialized equipment used to produce various automotive interior parts. They typically have multiple workstations, with rotary foaming platforms being particularly compact. These platforms enable cyclical production through rotation, allowing for simultaneous counting and foaming processes. The core design concept of rotary foaming platforms integrates multiple molds onto a rotating worktable. The intermittent or continuous rotation of the turntable sequentially transports the molds to stations such as injection, foaming, curing, cooling, and demolding, enabling parallel operation of multiple processes. This structure significantly shortens production cycles, improves space utilization, and supports rapid mold changes and flexible production. However, existing rotary structures still suffer from structural complexity, poor stability leading to inadequate mold support, and low rotational positioning accuracy, resulting in the risk of mold misalignment.

Multiple I-beams are present, with one end fixedly connected to the lower mounting plate. The I-beams extend radially along the lower mounting plate and are evenly distributed along its circumference. The upper mounting plate is coaxially arranged with the lower mounting plate and connected to the upper end face of each I-beam. A T-shaped bracket is provided between the outer ends of two adjacent I-beams. A mold support plate is provided on the top surface of the T-shaped bracket. A caster assembly is located on the bottom surface of the T-shaped bracket, and a track mounted on the ground is correspondingly provided below the caster assembly. A chain-fixed track is provided on the outer end of each I-beam.

[0006] Furthermore, the caster assembly includes a foot bracket connected to the bottom surface of the T-shaped bracket, the lower end of the foot bracket is connected to a caster axle, a caster bearing is sleeved on the caster axle, and a caster axle sleeve is sleeved on the caster bearing.

[0007] Furthermore, a platform is provided on the top surface of the I-beam, the platform is located inside the mold support plate, and a water vapor pipe support is provided on the platform, with multiple water vapor pipes arranged in a ring on the water vapor pipe support.

[0008] Furthermore, the lower mounting plate has an end positioning ring, and multiple I-beam positioning blocks are distributed in a ring on the outer side of the end positioning ring.

[0015] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0016] One such Figure 1-4The turntable structure shown for producing foamed automotive interior parts includes a center seat 1, a center bearing 2, a center bushing 3, a lower mounting plate 4, an upper mounting plate 5, and I-beams 6. The center bearing 2 is mounted on the central shaft of the center seat 1, the center bushing 3 is mounted on the center bearing 2, and the lower mounting plate 4 is mounted on the center bushing 3. Multiple I-beams 6 are present, with one end fixedly connected to the lower mounting plate 4. The lower mounting plate 4 has an end positioning ring 42, and multiple I-beam positioning blocks 41 are arranged in a ring around the outer side of the end positioning ring 42. The ends of the I-beams 6 abut against the outer surface of the end positioning ring 42, and the sides of the I-beams 6 are in close contact with the I-beam positioning blocks 41, ensuring even distribution of the multiple I-beams 6. The I-beams 6 extend radially along the lower mounting plate 4, and all I-beams 6 are of equal length. The upper mounting plate 5 is coaxially arranged with the lower mounting plate 4, and the upper mounting plate 5 is connected to the upper end face of the I-beams 6. A T-shaped bracket 7 is installed between the outer ends of two adjacent H-beams 6, connecting multiple H-beams 6 into a circular frame. A mold support plate 8 is installed on the top surface of the T-shaped bracket 7, on which a foaming mold is mounted. Casters are mounted on the bottom surface of the T-shaped bracket 7, with a corresponding track 13 installed on the ground below the casters, allowing the entire circular frame to rotate smoothly. Chain-fixed tracks 14 are installed at the outer ends of the H-beams 6, forming a ring. A drive device is connected to the chain fixed to the chain-fixed tracks 14, causing the entire turntable to rotate.

[0017] like Figure 4 As shown, the caster assembly includes a foot bracket 9 connected to the bottom surface of the T-shaped bracket 7. The lower end of the foot bracket 9 is connected to a caster axle 10. A caster bearing 11 is fitted on the caster axle 10, and a caster bushing 12 is fitted on the caster bearing 11. The caster bushing 12 is made of rubber and has a shock-absorbing and buffering function.

[0018] like Figure 1 As shown, a platform 15 is provided on the top surface of the I-beam 6. The platform 15 is located inside the mold support plate 8. A water vapor pipe support 16 is provided on the platform 15. Multiple water vapor pipes 17 are arranged in a ring on the water vapor pipe support 16. The water vapor pipes 17 are used to connect the foaming mold.

[0019] To ensure precise rotation and positioning of the entire turntable, an electrode mounting component 18 is connected to the upper end of the central shaft of the center seat 1. This electrode mounting component 18 is used to mount electrodes so that the circuitry on the mold is not affected by rotation. A proximity switch baffle mounting plate 19 is fitted onto the electrode mounting component 18. A probe mounting plate 20 is coaxially mounted on the upper mounting plate 5. The probe mounting plate 20 and the proximity switch baffle mounting plate 19 are arranged coaxially. The sensor mounted on the probe mounting plate 20 corresponds to the position of the mold. Thus, the proximity switch baffle on the proximity switch baffle mounting plate 19 is triggered by the sensor to achieve precise positioning. Since the proximity switch baffle mounting plate 19 is fixed, the proximity switch baffle, and different sensors triggering the proximity switch baffle, can accurately position the foaming mold on the mold support plate 8.

[0020] To facilitate operation by staff, an operating table 21 is provided on the outside of the turntable.
