Abstract

The invention relates to a large complex mold element separating and combining method and a large complex mold element separating and combining device. The large complex mold element separating and combining method comprises the following steps: separating a large complex or heavy mold device into a plurality of arrays; determining according to shapes and sizes of products required to be processed in selecting an element separating and combining method, and separating a large and heavy solid mold into mold elements at the X direction, or the Y direction or the Z direction; separating elements at two directions or three directions according to partial shapes of products; labeling each mold unit according to coordinates; then processing and manufacturing the mold micro elements; and assembling the mold micro elements according to labels so as to form a complete set of mold. The device adopting the method mainly comprises a mold frame, a No.1 mold unit group, a No.2 mold unit group, a No.3 mold unit group, a No.1 bolt component, a No.2 bolt component and a No.3 bolt component. Large and heavy screw plastic molds can be broken into parts through the element separating structure and combining method, thereby reducing the integral processing difficulty of large complex molds, and facilitating maintenance.

Description

technical field [0001] The invention relates to a structure and a molding method of a mold, in particular to a method and a device for combining large and complex hollow plastic product rotation molding molds. technical background [0002] At present, rotational molding products have gradually changed from single containers to high-precision vehicles, ships and other products to meet the needs of advanced manufacturing industries. Therefore, rotational molding has higher requirements on the machining accuracy of the rotational mold, the speed of opening and closing the mold, and the disassembly efficiency of the product. The production methods of rotational plastic mold mainly adopt three types: aluminum alloy casting mold, aluminum alloy welding mold and steel plate welding mold. The assembly method of the mold is basically connected and fixed by a large number of bolts. When processing rotationally molded products of different sizes and shapes, especially those with compl...
