Description

Technical Field

[0001] The utility model relates to the technical field of polystyrene molds, in particular to a production mold for polystyrene plates. Background Art

[0002] The polystyrene double-layer co-extruded foamed profile is a foamed profile produced by a double-layer co-extrusion process with a recycled polystyrene (PS) core layer and a high-impact polystyrene (HIPS) surface layer.

[0003] However, in the prior art, the production mold for polystyrene plates is generally a fixed structure in the shape of a groove. After the polystyrene plate is formed, it is not convenient to apply force to take it out, and the natural cooling and shaping of the polystyrene plate are slow, consuming a long time. Therefore, we propose a production mold for polystyrene plates. Summary of the Utility Model

[0004] The utility model provides a production mold for polystyrene plates, which solves the above-mentioned technical problems.

[0005] The solution of the utility model to the above technical problems is as follows: A production mold for polystyrene plates includes a tabletop. A mold bottom plate is fixedly installed in the middle of the tabletop. The outer side wall corners of the mold bottom plate are slidably fitted with an L-shaped frame mold. A fence is arranged at the edge of the upper end surface of the frame mold. The frame mold is connected to the tabletop through a sliding mechanism. An inverted U-shaped connecting frame is fixedly installed on the lower end surface of the tabletop. The connecting frame is connected with a steel wire through a control mechanism. The steel wire movably penetrates through the tabletop and is fixedly connected to the outer side wall of the frame mold. The steel wire is arranged in a horizontal U shape. A fixing piece is fixedly installed on the upper end surface of the tabletop and movably sleeved on the outer side wall of the steel wire. The fixing piece is fixedly connected to the frame mold through a spring movably sleeved on the outer side wall of the steel wire.

[0006] Preferably, the sliding mechanism includes a chute horizontally opened on the upper end surface of the tabletop, and the frame mold is slidably connected to the inner side wall of the chute.

[0007] Preferably, the control mechanism includes a motor fixedly installed vertically on the lower end surface of the connecting frame. The output shaft of the motor rotates through the connecting frame. A winding wheel is fixedly installed on the output shaft of the motor. The end of the steel wire is fixedly connected to the winding wheel.

[0008] Preferably, guide wheels are respectively rotatably installed on the upper end surface and the lower end surface of the tabletop, and the steel wire is slidably fitted with the surface of the guide wheels.

[0009] Preferably, a cooling pipe is fixedly penetrated through the tabletop. The cooling pipe is continuously bent. Threaded interfaces are respectively arranged at both ends of the cooling pipe.

[0010] The beneficial effects of the utility model are:

[0011] 1. By setting up the mold bottom plate and the frame mold to be combined into a mold groove, after the polystyrene board is shaped, the motor can be used to drive the winding wheel to rotate. The winding wheel indirectly pulls the frame mold to move by winding the steel wire, so that the frame mold is separated from the mold bottom plate, exposing the edge of the polystyrene board for easy removal.

[0012] 2. By setting up the cooling pipes, the cooling pipes are distributed in a continuously bent shape in the tabletop. Cold water is introduced into the cooling pipes, and the flowing cold water exchanges heat with the tabletop, the mold bottom plate and the frame mold to accelerate cooling and shaping, improve production efficiency. At the same time, threaded interfaces are provided at both ends of the cooling pipes for convenient docking.

The frame mold 3 is connected to the tabletop 1 through a sliding mechanism. The sliding mechanism includes a chute transversely opened on the upper end surface of the tabletop 1. The frame mold 3 is slidably connected to the inner side wall of the chute. The chute is provided to connect the frame mold 3 and the tabletop 1, so that the frame mold 3 can move stably along the tabletop 1. A concave-shaped connecting frame 4 is fixedly installed on the lower end surface of the tabletop 1. The connecting frame 4 is connected to a steel wire 5 through a control mechanism. The steel wire 5 movably penetrates the tabletop 1 and is fixedly connected to the outer side wall of the frame mold 3. The steel wire 5 is arranged in a horizontal U shape. A fixing piece 6 is fixedly installed on the upper end surface of the tabletop 1 and is movably sleeved on the outer side wall of the steel wire 5. The fixing piece 6 is fixedly connected to the frame mold 3 through a spring 7 movably sleeved on the outer side wall of the steel wire 5. A cooling pipe 11 is fixedly penetrated through the tabletop 1. The cooling pipe 11 is continuously bent. Threaded interfaces 12 are respectively arranged at both ends of the cooling pipe 11.

The motor 8 drives the winding wheel 9 to rotate, and the steel wire 5 is wound around the winding wheel 9. The steel wire 9 pulls the frame mold 3 to move outward, separating the frame mold 3 from the mold bottom plate 2, exposing the edge of the formed polystyrene board, facilitating the removal of the polystyrene board. After the motor 8 is turned off, the frame mold 3 is reset under the push of the spring 7, and the frame mold 3 can be re-joined with the mold bottom plate 2.
