Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, and in particular to a vertical plastic product injection molding equipment. Background Technology

[0002] In the field of plastic product processing, vertical injection molding equipment is widely used in the production of small parts and precision products due to its small footprint and convenient operation. Existing vertical injection molding equipment typically adopts a vertical layout, arranging the injection unit and mold clamping unit in a vertical direction. Molten plastic is injected into the mold cavity through the injection system, and the product is formed after cooling and solidification. It is suitable for processing and molding various thermoplastic plastics. From a structural perspective, existing vertical plastic injection molding equipment mainly consists of an injection mechanism, a mold clamping mechanism, a drive system, and a control system. The injection mechanism includes a barrel, screw, and nozzle, responsible for melting and injecting the plastic. The mold clamping mechanism typically uses vertically arranged mold plates to install and fix the mold and realize the opening and closing actions. The drive system is usually powered by a hydraulic device or servo motor to control the operation of each mechanism. The control system uses a programmable logic controller to adjust parameters such as injection speed, pressure, and temperature to ensure the stability of the production process. However, existing equipment has significant shortcomings in actual operation. First, mold installation relies on manual placement, and the lack of precise positioning assistance easily leads to misalignment between the nozzle and the mold inlet, resulting in molten material leakage and insufficient material in the finished product, seriously affecting product quality stability. Second, after production, operators must directly remove the mold from below the outlet. At this time, the mold may still be at a high temperature, and the residual molten plastic at the outlet poses a risk of dripping, easily causing burns and other safety accidents, posing a significant operational safety hazard. Therefore, a vertical plastic product injection molding equipment is proposed to solve the above problems. Utility Model Content

[0018] Working principle: The material enters the material barrel (33) through the feed port (3). The heating wire (13) inside the material barrel (33) works to heat the material and melt it into a state suitable for injection molding. At the same time, the motor (12) in the second protective shell (11) starts and its output end drives the stirring blade (14) to rotate, stirring the melted material to ensure uniform mixing. When the worker is ready to perform injection molding, the mold to be fixed is placed on the platform (25), and the electric push rod (26) starts and its output end pushes the push plate ( 22) Move the push plate (22) to move the platform (25) and related components to the appropriate position. The cross plate (24) moves under force, which drives the fixed shaft one (17) to move. The fixed shaft one (17) drives the fixed shaft two (18) to move through the rotating plate (23). The fixed shaft two (18) then drives the moving plate (19) to slide on the track (20). The clamping plate (21) on the inner side of the moving plate (19) moves accordingly, clamping and fixing the mold from both sides to ensure the mold position is stable during the injection molding process. After clamping the mold, the equipment needs to send the mold to the designated location. The device is positioned and started by motor 2 (27) inside the outer casing (1). Its output drives the rotating disk (28) to rotate. The rotating disk (28) drives the push rod (30) to move through the connecting rod (29). The square plate (32) on the outside of the push rod (30) slides in the sliding rail (31) to guide and restrict the movement direction of the push rod (30). The left side of the push rod (30) drives the slide plate (16) to slide between the slide rails (8) on the top of the outer casing (9), thereby driving the platform (25) and the mold to move, which is convenient for different processes. The position switching improves the working efficiency of the equipment. When the mold is delivered to the designated position, the injection process begins. The electric push rod (10) in the bottom protective shell (6) of the top plate (4) is activated. Its output end pushes the sliding plate (7) to slide down on the sliding rod (5). The sliding plate (7) drives the material barrel (33) to move down synchronously, so that the nozzle (15) at the top of the material barrel (33) is close to the feed port of the mold. The heated and stirred material in the material barrel (33) is injected into the clamped and fixed mold through the nozzle (15) to complete the injection operation.
