Machining process for injection molding machine frame

Abstract

The invention discloses a machining process for an injection molding machine frame. The machining process comprises the steps that milling machining is conducted on a main bearing face and side faces through a five-face gantry, a bottom face is positioned through the first procedure, and the bottom face is machined through the second procedure. The machining process comprises the following specific steps that firstly, the machine frame is fixed to a fixture, and the design size of the main bearing face and the design sizes of the four side faces of the machine frame are subjected to milling machining through the five-face gantry; secondly, the height of the machine frame on the fixture is adjusted so that the machine frame can be positioned, and the fixture is provided with a plurality of spiral clamping positioning mechanisms and a plurality of supporting height adjusting mechanisms; and thirdly, the size of the bottom face of the machine frame is machined, and after the second step is completed, the five-face gantry is adjusted to conduct milling machining on the bottom face of the machine frame. According to the machining process for the machine frame, the machining precision requirements of the machine frame components subjected to the machining process are met, the service life is prolonged, and positioning is precision; when the machining process is designed, one-engineering rough and finish machining is conducted on the whole machine frame through a floor gantry machine tool, and supporting points of the fixture are increased, so that all precision requirements of the component are met.

Description

technical field [0001] The invention relates to the technical field of machining technology for injection molding machine frames, in particular to the machining technology for injection molding machine frames. Background technique [0002] During the welding process of the large frame, even if the operator welds the large frame according to the prepared process card, there will still be welding misoperations, or some instructions are not clear or specific, resulting in operational errors. In addition, large-scale racks undergo other heat treatment, surface treatment, or painting treatment directly after welding, which will cause large deformations, which will cause large errors in the installation of large racks, making it difficult to locate and cause installation problems. Various accessories on the rack need to be readjusted or scrapped, which wastes cost and lengthens the manufacturing process of large equipment. [0003] In addition, the large-scale frame needs to be f...

Problems solved by technology

However, this kind of fixture and process method, on the one hand, takes a long time to hoist and turn over a large frame, and on the other hand, bumps and bumps are inevitable during operation, causing damage to the appearance, and the processing cycle is also long and the efficiency is low.
