Description

Technical Field

[0001] The utility model belongs to the technical field of product cutting devices, in particular to a plastic molding die product cutting device. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts. Different molds are composed of different parts. The mold has a specific contour or inner cavity shape. The use of a contour shape with a cutting edge can make the blank separate (punch out) according to the contour shape. The use of an inner cavity shape can make the blank obtain a corresponding three-dimensional shape. The mold generally includes a movable mold and a fixed mold (or a male mold and a female mold). The two parts can be separated or combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming. However, the width of the molding mold of some plate plastic products or sheet plastic products is generally greater than the width of the sheet product. After the plastic mold performs the molding step on the plate plastic product, it is necessary to cut and remove the excess edge material of the plate plastic product. The existing technology mainly cuts the edge material of the mold by a cutting blade.

[0003] A Chinese patent with publication number "CN207789053U" discloses a cutting device for a plastic product molding machine, which includes a workbench, a bearing, a slider, a support plate, a servo motor, a cam, a roller, a fixed box, a baffle, a connecting block, a blade, a roller, a rectangular groove, a rotating shaft, a compression spring and a mounting frame. The workbench is provided with a mounting frame, and two rotating shafts are arranged side by side at the lower position between the two side walls of the mounting frame. The rotating shafts are provided with rollers, and bearings are respectively sleeved at both ends of the rotating shaft. The bearings are respectively arranged on the two side walls of the mounting frame, and a support plate is provided above the roller. A blade is provided at the bottom of the support plate, and the blade is located directly above the gap between the two rollers. Slide blocks are respectively provided at both ends of the support plate, and slide grooves are respectively provided in the vertical direction inside the two side walls of the mounting frame. The sliders are arranged in the slide grooves inside the two side walls of the mounting frame, and the top of the support plate is connected to one end of the connecting block.

[0004] During use, the above device can perform cutting quickly. However, during the cutting process, the roller lacks a driving structure, and the cut plastic product needs to be taken out manually after the plastic product is cut, which results in low cutting efficiency. At the same time, during the cutting process, there is a lack of a stable positioning structure, and the roller has a rolling characteristic. During the cutting process, the pressure of the cutter can easily cause the roller to rotate, which can easily lead to deviations during the cutting process, affecting the flatness of the cut surface of the plastic product.
