Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roto-molded parts shaping, in particular to a box roto-molded parts shaping tool. Background Art
[0002] Rotomolding, also known as rotational molding, rotational molding, and rotational molding, is a method for hollow molding thermoplastics. The method involves first adding the plastic raw material into a mold, which is then continuously rotated along two perpendicular axes and heated. Under the action of gravity and heat, the plastic raw material in the mold gradually and evenly spreads, melts, and adheres to the entire surface of the mold cavity, forming it into the desired shape. The product is then cooled and shaped. Because rotomolded boxes are formed in one step using the rotomolding process, their surface is more durable, so the box body is shaped during processing.
[0003] In the prior art, after rotomolding, box-type rotomolded products need to be removed from the rotomolding machine. An air compressor is used to first infuse air into the box to prevent the inner wall from caving during the cooling process. This air-blowing process is controlled by workers based on experience, so excessive air-blowing often causes the box to bulge, while insufficient air-blowing causes the box to sag during cooling. This, in turn, causes the product to fail to meet dimensional requirements, significantly affecting the product qualification rate. In light of this, we have introduced a rotomolded box shaping tool. Utility Model Content
[0004] The purpose of the present invention is to provide a box body rotational molding tool to solve the problems raised in the above background technology.

[0008] The positioning ring is arranged at the output end of the cylinder, and a positioning mechanism is arranged on one side of the positioning ring. The positioning seat of the positioning mechanism drives the extrusion plate and the shaping plate to move, so that the shaping plate clamps and shapes the rotational molding box inside the outer frame.
[0009] Preferably, the positioning mechanism includes bolts connecting the positioning ring and the positioning seat, the positioning seat is connected to the side of the extrusion plate, the positioning seat and the extrusion plate are fixedly arranged, the shaping plate is fixedly connected to one side of the extrusion plate, the number of the shaping plates is two groups, and they are located on the inner side of the outer frame, and the shaping plates are used to shape the processed and formed rotational molded box.
[0010] Preferably, a fixed plate is connected to the outer side of the outer frame, and a limiting rod is connected to the side of the extrusion plate, and the limiting rod passes through the fixed plate. When the extrusion plate moves, the limiting rod on its side slides along the fixed plate to ensure the accuracy of the moving direction of the extrusion plate.
[0011] Preferably, the bottom of the shaping plate is connected to a limiting wheel, which is connected to the bottom of the shaping plate by screws, and the limiting wheel is slidably connected to the inner bottom wall of the outer frame.
[0012] Preferably, bases are connected to the bottom of the outer frame at equal intervals, and the arrangement of the bases allows the outer frame to remain stable when placed.
[0013] Compared with the existing technology, the beneficial effects of the present invention are as follows: the present invention can accurately control the movement and clamping force of the shaping plate through the coordinated action of the cylinder drive and the positioning mechanism, thereby avoiding the problem of box bulging or sinking caused by workers relying on experience to control the blowing in the traditional process, effectively ensuring the product size qualification rate, and effectively avoiding the defects of the rotomolded box body such as sinking and deformation during the cooling and shaping process of the rotomolded box body, thereby ensuring the product size qualification rate;
[0014] The outer frame and its bottom base provide a stable support structure for the entire tooling. The positioning frame, side plates, fixed plates and other components cooperate with each other, and the limiting rods and limiting wheels guide and limit the movement of the extrusion plate and the shaping plate, making the tooling structure stable during operation and ensuring the accuracy and reliability of the shaping operation.
