Machining method of universal die holder

Abstract

The invention relates to a machining method of a universal die holder. The machining method comprises the following steps: step 1, performing rough machining operation on upper and lower end surfacesand four circumferential surfaces of a movable template and a fixed template; step 2, centering and boring the movable template and the fixed template and respectively finding out centers of the movable template and the fixed template; step 3, fixing the movable template and the fixed template to a CNC machining center above and below, enabling the centers of the movable template and the fixed template to be superpose vertically meanwhile guide column holes of the movable template and the fixed template are machined with the center of the movable template as a central point; step 4, continuingto ream the guide column holes with the center of a guide column hole of the movable template as the center and machining guide sleeve holes; step 5, machining guide sleeves; step 6, machining guidecolumns; step 7, assembling the movable template, the fixed template, the guide columns and the guide sleeves to be a die holder. Firstly, the movable template and the fixed template are drilled withthe guide column holes. Secondly, reaming operation is carried out on the guide column hole in the movable template. Therefore, relative precision between the guide column holes and the guide sleeve holes is ensured.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to a processing method for a general mold base. Background technique [0002] The mold base is the support of the mold. For example, on the die-casting machine, the parts of the mold are combined and fixed according to certain rules and positions, and the part that enables the mold to be installed on the die-casting machine is called the mold base. It consists of a push-out mechanism, a guide mechanism, and a pre-reset mechanism. Composed of mold foot pads and seat plates.

[0003] TV is a daily necessities and occupies an important position in people's life. In the production and processing of TV, a variety of components are needed. Among them, the TV frame is an important part of the TV. The TV frame needs to be used in the production Universal formwork, general formwork is generally composed of movable template, fixed template, guide sleeve and guide column, but during production and processing, since the holes on the movable template and the fixed template are processed separately, the distance between the two holes The accuracy cannot be mutually guaranteed, and the accuracy of the guide post and guide sleeve is also poor, resulting in the later assembly accuracy not meeting the requirements
