Fully-electric injection molding machine

Abstract

The invention provides a fully-electric injection molding machine, and belongs to the technical field of machinery. The fully-electric injection molding machine solves the problems that an existing injection molding machine is inconvenient to use, is not reliable in mounting, has friction and collision among parts and is low in equipment precision. The fully-electric injection molding machine comprises a base, a regulating mechanism, a movable molding board, a seat inlet mechanism and a material barrel regulating mechanism, wherein a drawbar is fixedly connected on a fixed molding board; the movable molding board which moves relative to the fixed molding board is movably arranged on the base; the drawbar penetrates through the movable molding board, and is not in contact with the movable molding board; a linear guide rail is arranged between the movable molding board and the base; the bottom of the movable molding board is mounted on the linear guide rail, and moves along the track of the linear guide rail, so that the movable molding board is prevented from moving in a mode of clinging to the drawbar, and therefore, surface precision of the drawbar is protected.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an all-electric injection molding machine. Background technique [0002] Injection molding machine is the main molding equipment for making thermoplastics or thermosetting materials into various shapes of plastic products using plastic molding molds. In the existing injection molding machine, it includes injection system and mold clamping system: [0003] 1. The mold clamping system can ensure that the mold is closed, opened and the product is ejected; at the same time, when the mold is closed, it can provide enough clamping force to the mold to resist the cavity pressure generated by the molten plastic entering the cavity and prevent the mold from cracking.

Problems solved by technology

[0004] (1) The moving platen is one of the important components of the mold clamping system. In the prior art, there is a copper gasket between the moving platen and the tie rod, which is used to protect the tie rod and avoid damage to the tie rod, but the copper The setting of the gasket causes friction between the tie rod and the copper gasket, thereby reducing the surface accuracy of the tie rod and resulting in a decrease in the quality of the processed product. Therefore, technicians are required to regularly apply lubricating oil on the copper gasket, which increases the It is inconvenient for technicians to control the accuracy of the equipment due to the operation steps of the equipment

[0005] (2) The fixed formwork is one of the other important components of the mold clamping system. In the prior art, the fixed formwork and the tie rods often cause a slight deviation of the fixed formwork due to the long service time of the equipment, which makes the tie rods It will not be vertical to the fixed template, causing friction between the parts of the equipment during the working process of the injection molding machine, thus causing the equipment to be damaged

[0007] (1) The barrel is an important part of the injection system, but when installing the barrel, the central axis of the barrel and the central axis of the injection plate often do not overlap, and the screw is installed in the barrel, but the central axis of the screw and the center axis of the injection plate do not overlap. The central axis of the injection plate overlaps, which will cause friction between the screw and the barrel when the injection system is working, resulting in damage to the screw or barrel

[0008] (2) The seat-in mechanism is used to transport the injection device. Therefore, the seat-in is another important part of the injection system. In the prior art, when the seat-in mechanism moves close to the fixed template, hard collisions often occur, making The seat-in device is damaged, resulting in material leakage, which wastes resources. In addition, in most seat-in devices, the screw locking force with the screw rod is not enough, which will also cause material leakage when the injection device injects materials, resulting in waste of resources
