Automatic demolding and trimming PP plastic part forming equipment and process

Abstract

The invention relates to automatic demolding and trimming PP plastic part forming equipment and a process. The equipment comprises a forming device which comprises a convex mold mechanism, a concave mold mechanism and a material injection mechanism arranged above the position between the convex mold mechanism and the concave mold mechanism. The equipment also comprises a discharging device arranged on one side of the material injection mechanism and a trimming device arranged on the same side of the convex mold mechanism and the concave mold mechanism. The discharging device comprises a fixingmechanism which adsorbs and fixes leftover materials of a desk plate, an overturning mechanism which drives the fixing mechanism to overturn to be in a flatwise state together with the desk plate anda moving-out mechanism which drives the fixing mechanism to be moved out to reach the trimming device together with the desk plate; the trimming device comprises a push-down mechanism which pushes the desk plate to move downwards vertically and settles the material flash wastes of the desk plate and a cropping mechanism which crops the leftover materials in the reset process of the push-down mechanism. The equipment provided by the invention solves the problems that a plastic desk plate is low in forming and demolding efficiency, the equipment is low in efficiency and wastes labor as a resultof manual operation needed by discharge, the surface of the desk plate is easily damaged and the leftover materials of the desk plate are inconveniently cropped in the discharging process, and the cropping effect is poor and the efficiency is low.

Description

technical field [0001] The invention relates to the technical field of plastic part forming equipment, in particular to a PP plastic part forming equipment and process for automatic demoulding and trimming. Background technique [0002] Many products used in life are plastic products. Some existing table tops are also formed by plastic blow molding. During the molding process of the table tops, there are often waste edges at the corners. To clean up the waste edge, in the prior art, the waste edge is generally cut off manually using a cutter, which not only consumes manpower but also has poor cutting effect, easily hurts the table board, and is inefficient. [0003] Aiming at the low degree of automation, poor cutting effect and low efficiency of plastic table waste edge removal, it is urgent to design a device to realize the rapid and automatic removal of table waste edge, improve its efficiency, and improve the waste edge removal while liberating manpower. The effect guar...

Problems solved by technology

[0004] One of the purposes of the present invention is to provide a PP plastic parts molding equipment for automatic demoulding and edge trimming in view of the deficiencies of the prior art, which can be achieved by setting a discharge device and using negative pressure to absorb the edge waste of the table. The formed table board is quickly demoulded and taken out from the forming device to one side, and the removed table board is quickly and automatically cut off edge waste by setting the trimming device, and the entire demoulding and retrieving process is realized. Automation, and at the same time, it will not cause damage to the formed table during the process of retrieving the material, thereby solving the problem of low demoulding efficiency during the molding process of the plastic table, and the need for manual operation when the material is discharged, which is inefficient and labor-intensive , the surface of the table board is easily damaged during the discharging process, and it is inconvenient to cut the edge waste of the table board, the cutting effect is poor and the efficiency is low
