A main box of an injection molding machine and a manufacturing method thereof

Abstract

The invention relates to an injection molding machine main box. The injection molding machine main box comprises a front plate, side plates, two side supports and a bottom support, wherein the side plates are L-shaped, a hole corresponding to the front plate is formed in each side plate; the L short sides of the side plates are arranged at the lower end; the side plates are symmetrically mounted on two sides of the short side of the bottom support and are connected with the short side of the bottom support; the two side supports are mounted on two sides of the long side of the bottom support respectively and are connected with the side plates; the two side supports are rectangular iron plates to be folded to be n-shaped; a circuit board hole corresponding to the I / O area and size of a circuit board and the circuit board for placing are arranged on the front plate; and two sides of the circuit board hole are folded to form hole plates for fixing screws of the fixed circuit board, and the hole plates are used for vertically fixing the circuit board onto the front plate. According to the injection molding machine main box, the specifications and marks of host machine function signals are clear, the circuit board is easily changed, the vibration prevention performance is high, and the main box is easy to maintain.

Description

technical field [0001] The invention belongs to the technical field of injection molding machines or other industrial PLC mainframes, and in particular relates to a main casing of an injection molding machine and a manufacturing method thereof. Background technique [0002] Some existing plug-in main chassis structures are usually relatively simple in terms of shockproof and fixed design. If a single circuit board is to be replaced separately, the entire fixed plate (for shockproof) needs to be disassembled first, and then the required single circuit board can be replaced. One-chip circuit boards, so it takes a lot of man-hours to maintain, and the product's functional specifications and appearance are also not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a main box body of an injection molding machine and its structural design method, which solves the problem that the entire fixing plate (for anti-vibra...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a main box body of an injection molding machine and its structural design method, which solves the problem that the entire fixing plate (for anti-vibration) needs to be disassembled before replacing a single circuit board. The need for single-chip circuit boards leads to time-consuming repairs and problems in the product's functional specifications and appearance.
