Vertical and Horizontal Injection Molding Machines: A Flexible Solution for Industrial Manufacturing
Date：2024-11-15
In modern industrial production, injection molding machines are crucial equipment used for large-scale production of various plastic products. Among them, vertical and horizontal injection molding machines play a key role in many industrial applications due to their unique design and functions. This article will provide an in-depth introduction to the characteristics, structural functions, and application scenarios of vertical and horizontal injection molding machines, demonstrating their importance in modern manufacturing.
1、 Basic Overview of Vertical and Horizontal Injection Molding Machines
The vertical and horizontal injection molding machine combines the advantages of both vertical and horizontal injection molding machines. Its injection device and locking device are located on the same vertical centerline, and it has the characteristics of both vertical and horizontal injection molding machines. This design enables the vertical and horizontal injection molding machine to achieve precise mold closure while also being easy to install and operate. It occupies a smaller area, only about half of a horizontal machine, but its production efficiency has been nearly doubled.
2、 Structure and Function of Vertical and Horizontal Injection Molding Machines
1. Injection system
The injection system is the core part of the injection molding machine, responsible for heating and melting plastic raw materials and injecting them into the mold. Common injection systems include plunger, screw, and screw pre molded plunger injection, with screw being the most widely used. The screw injection molding machine transports plastic particles in the hopper forward through a rotating screw, and melts them under the action of heating and compression. Then, the molten plastic is injected into the mold cavity at a set pressure and speed.
2. Mold closing system
The function of the mold closing system is to ensure the closure, opening, and ejection of the product from the mold. It consists of a mold clamping device, a mold adjustment mechanism, an ejection mechanism, front and rear fixed templates, a moving template, a mold clamping oil cylinder, and a safety protection mechanism. During the mold clamping process, the clamping system needs to provide sufficient locking force to resist the pressure generated when molten plastic enters the mold cavity and prevent mold cracking from causing product defects.
3. Hydraulic system
The hydraulic system provides power for various actions of the injection molding machine, including mold closing, injection, ejection, and other steps. It mainly consists of oil pump, hydraulic motor, valve control components, and oil tank. The hydraulic system achieves precise control and adjustment of various parts of the machine by controlling the flow and pressure of oil.
4. Electrical control system
The electrical control system and hydraulic system work together to achieve process control of the injection molding machine. It includes various electrical appliances, electronic components, instruments, heaters, and sensors. Electrical control systems typically have four control modes: manual, semi-automatic, fully automatic, and adjustable, to meet different automation production needs.
5. Heating/cooling system
The heating system is used to heat the plastic raw materials in the barrel and nozzle to a viscous state, usually using an electric heating coil for heating. The cooling system is used to control the oil temperature and avoid faults caused by excessive temperature. The other part of the cooling system is used at the discharge port of the material pipe to prevent the raw materials from melting and blocking at the discharge port.
6. Lubrication system
The lubrication system provides lubrication for the moving template, mold adjustment device, connecting rod machine hinge and other parts of the injection molding machine, reducing energy consumption and improving component life. Lubrication can be done manually on a regular basis or set to automatic electric lubrication.
7. Security Protection System
The safety protection system includes mechanical, hydraulic, and electrical safety protection devices to ensure the safety of operators and equipment. The main components include safety doors, safety barriers, hydraulic valves, limit switches, and photoelectric detection elements, which achieve interlocking protection for the dangerous state of the machine through these devices.
3、 Maintenance and upkeep of vertical and horizontal injection molding machines
Hydraulic oil management: Regularly check the storage condition of hydraulic oil, keep the oil quality clean, and filter it when refueling. If the oil quality deteriorates or impurities increase, it should be replaced or replenished with new oil in a timely manner.
Lubrication management: lubricate the relative moving parts on time, such as the conveyor belt and mechanical arm. The lubrication method can be regular manual lubrication or setting up an automatic lubrication system.
Tighten parts: Regularly inspect and tighten various parts on the machine to ensure that they are not loose or damaged, especially the connection between the tension belt conveyor and the robotic arm.
Circuit inspection: Regularly check whether there is water or oil entering the electrical control box to ensure the safety of wire connections and avoid circuit failures caused by moisture or other reasons.
Mechanical component maintenance: Check the working status of mechanical components such as bearings, hydraulic components, etc., replace severely worn parts in a timely manner, and ensure the normal operation of the equipment.
4、 Application fields of vertical and horizontal injection molding machines
Vertical and horizontal injection molding machines are widely used in the following fields due to their high efficiency, energy saving, and strong adaptability:
Automotive manufacturing: used for the production of automotive components such as bumpers, dashboards, door handles, etc.
Electronic appliances: suitable for the production of high-precision plastic products such as phone cases, computer cases, and home appliance accessories.
Medical equipment: used for manufacturing high-precision medical devices and instrument casings, such as syringes, medical tubing, etc.
Daily consumer goods: such as disposable plastic tableware, drinking cups, children's toys, etc.
Packaging industry: producing various types of plastic containers, packaging boxes, beverage bottles, etc.
