Description

Technical Field

[0001] The utility model discloses a fixture, belonging to the technical field of die fixtures, and particularly relates to a special C-shaped fixture for a rotational molding steel plate die. Background Technique

[0002] The rotational molding steel plate die is a tool for manufacturing rotational molding steel plates. The rotational molding steel plate is a metal plate formed by hot rolling or cold rolling and then processed through a rotational molding (also known as roll pressing) process. This processing process can enhance the surface quality and specific shape of the steel plate.

[0003] The design and manufacture of the rotational molding steel plate die are very crucial because it directly affects the quality and shape of the final product. These dies usually require precise machining and high wear resistance to cope with the high-intensity production environment and long-term use requirements.

[0004] The rotational molding steel plate die is composed of an upper die and a lower die. The upper die and the lower die are usually fixed by bolts or hinges and then combined for molding work. However, using this fixing method is very inconvenient for disassembly and assembly. It requires manual use of a wrench to tighten and fix one by one, and the efficiency is very slow.

[0006] Technical solution: A special C-shaped fixture for a rotational molding steel plate die, the C-shaped fixture includes: a C-shaped fixed seat, an upper die clamping seat, a lower die clamping seat, and a driving arm;

[0007] The upper die clamping seat is fixedly installed at the upper end point of the C-shaped fixed seat; the lower die clamping seat is movably installed at one end of the driving arm; the driving arm is movably installed at the lower end point of the C-shaped fixed seat, and the rotation of the driving arm drives the rotation of the lower die clamping seat.

[0008] In a further embodiment, the driving arm is divided into a force arm and a clamping arm;

[0009] The clamping arm is provided with a first pin hole and a second pin hole from top to bottom, and the lower die clamping seat is installed on the clamping arm of the driving arm through a pin shaft in cooperation with the first pin hole;

[0010] The driving arm is installed at the lower end point of the C-shaped fixed seat through a pin shaft in cooperation with the first pin hole.

[0011] In a further embodiment, a screw hole is provided at the upper end point of the C-shaped fixed seat, and the upper die clamping seat is screwed into the screw hole at the upper end point of the C-shaped fixed seat.

[0012] In a further embodiment, the upper die clamping seat and the lower die clamping seat are provided with symmetrical horizontal clamping surfaces.

[0013] In a further embodiment, the force arm of the driving arm is bent to one side and forms an obtuse angle with the clamping arm.

[0014] In a further embodiment, the top surface of the lower die clamping seat is a horizontal clamping surface, and one side surface is a limiting plane, and the width of the limiting plane is greater than or equal to the width of the clamping arm of the driving arm.

[0015] Beneficial effects: In the present utility model, the upper die clamping seat and the lower die clamping seat are arranged at both ends of the C-shaped fixing seat. The two clamping seats are fixed to the upper die and the lower die of the mold, and are driven by the driving arm. By controlling the force arm of the driving arm, the lower die clamping seat is driven to move, so as to realize the combination and separation of the upper die and the lower die. Therefore, the present utility model can quickly realize the working states of the upper die and the lower die of the mold, thus greatly improving the working efficiency. Description of the Drawings
