Description

TECHNICAL FIELD

[0001] The utility model relates to mould processing technical field, concretely is a quick film die set structure. BACKGROUND

[0002] Mold is the various moulds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods. In short, mold is a tool for making shaped objects. Such a tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object through the change of the physical state of the formed material.

[0003] The invention patent with the publication number CN111872302B discloses a mold, which comprises: a first sub-mold, a first guide block and a second guide block are arranged on the first sub-mold; and a second sub-mold, the first sub-mold and the second sub-mold can enclose a forming cavity, and a first guide groove and a second guide groove are arranged on the second sub-mold; wherein the first guide block is used for plug-in cooperation with the first guide groove, and is only used for limiting the freedom of relative movement of the first sub-mold and the second sub-mold along the X-axis direction; the second guide block is used for plug-in cooperation with the second guide groove, and is only used for limiting the freedom of relative movement of the first sub-mold and the second sub-mold along the Y-axis direction. The processing difficulty is reduced, and the high-precision matching surface can be processed more conveniently under the low-difficulty processing condition. The two sub-molds can enclose the forming cavity when they are closed (i.e., when they are closed together), in order to ensure the stability of the formed cavity, guide members for guiding during closing are arranged on the two sub-molds. In order to improve the closing precision, the guide members need to have high matching precision, which leads to high processing difficulty of the guide members, and the high processing difficulty makes it difficult to process high-precision guide members.

[0004] When the workpiece is processed, each group of molds can only process one type of workpiece. When different workpieces are processed, the molds need to be replaced frequently. The existing molds are fixed on the stamping equipment by a plurality of bolts during use. After the bolts are disassembled, the upper mold will directly fall down, and the lower mold will collide with other structures in the stamping equipment when it is pulled out, which makes it inconvenient to quickly replace the molds during use. To solve the above problems, a quick film die set structure is proposed in the present application. UTILITY MODEL CONTENTS
