Injection mold of junction box

Abstract

The invention belongs to the technical field of molds, and particularly relates to an injection mold of a junction box. The injection mold comprises a mold shell, a casting cavity, a rotating rod, a first conic gear, a second conic gear, a screw, a threaded hole, a groove, a rotating plate, a square rod, an L-shaped plate, a moving rod, a connecting rod, a guide rod, a sliding groove, a spring, apress plate and a fastening screw. According to the injection mold, the rotating rod rotates to drive the first conic gear to rotate, the first conic gear rotates to drive the second conic gear to rotate, the second conic gear rotates to drive the screw to rotate, the screw rotates to move along the threaded hole, the screw moves to drive the moving plate to move, the moving plate moves to push out a junction box casting, and the junction box casting can be taken out conveniently; the connecting rod is moved and moves to drive the L-shaped plate through the moving rod to move, the L-shaped plate moves to be separated from the square rod, and the rotating rod can rotate conveniently; and the connecting rod compresses the spring while moving, the spring is compressed to generate elastic force, automatic rest of the L-shaped plate is facilitated by the design of the spring, and the rotating rod can be fixed conveniently.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to an injection mold for a junction box. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] The injection mold of the junction box currently used has certain defects. It lacks a supporting mechanism. After the injection molding is completed, the junction box is located inside the casting cavity, which is inconvenient to take out the junction box, thereby reducing work efficiency. At the same time, it lacks a limit mec...

Problems solved by technology

[0006] The purpose of the present invention is to provide an injection mold for a junction box in order to solve the above problems. The present invention rotates and rotates Rod, the rotation of the rotating rod drives the first rotation of the bevel gear, the first rotation of the bevel gear drives the second rotation of the bevel gear, the second rotation of the bevel gear drives the screw to rotate, the screw rotates to move along the threaded hole, the screw moves to drive the moving plate to move, and the moving plate Move the junction box casting out to facilitate the removal of the junction box casting, which solves the problem that the injection mold of the junction box currently used has certain defects and lacks a supporting mechanism. After the injection molding is completed, the junction box is located inside the casting cavity, which is inconvenient for the junction box. Take it out, and then reduce the problem of work efficiency. The present invention moves the connecting rod by adding square rods, L-shaped plates, moving rods, connecting rods, guide rods, chutes and springs, and the connecting rods move to drive the L-shaped plates to move through the moving rods. The movement of the L-shaped plate is separated from the square rod, which facilitates the rotation of the rotating rod. When the connecting rod moves, the spring is compressed, and the spring is compressed to generate elastic force. The design of the guide rod improves the stability of the connecting rod. The design of the spring is convenient for L-shaped The automatic reset of the plate is convenient for fixing the rotating rod, which solves the problem that the injection mold of the junction box currently used lacks a limit mechanism. Due to the influence of the external environment, the rotating rod is prone to rotate, causing the moving plate to not be flush with the bottom of the casting cavity , the disadvantages of reducing the quality of junction box castings
