Nowadays, many children like to play with kinds of plastic toys. But do you know how plastic toys are made? I believe many people are curious. Yes, most plastic toys are made by high quality Injection molding machine for plastic toys. Today this article will mainly introduce the high quality Injection molding machine for plastic toys.

What is the High Quality Injection Molding Machine for Plastic Toys  

Injection molding machine is also known as injection machine. It is the main molding equipment for making thermoplastic or thermosetting plastics into various shapes of plastic products using plastic molding dies. It is divided into vertical, horizontal, and all-electric injection molding machines. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it shoot out and fill the mold cavity.

The Structures of the High Quality Injection Molding Machine for Plastic Toys

An injection molding machine for plastic toys is usually composed of an injection system, a clamping system, a hydraulic drive system, an electrical control system, a lubrication system, a heating and cooling system, and a safety monitoring system. Next I will introduce four main structures separately.

1️⃣ Injection System

The function of the injection system: The injection system is one of the most important components of the injection molding machine. Generally, there are three main forms: plunger type, screw type, and screw preplasticized plunger injection type. The screw type is the most widely used. Its function is that in a cycle of the plastic injection machine, it can heat and plasticize a certain amount of plastic within a specified time, and then inject the molten plastic into the mold cavity through the screw under a certain pressure and speed. After the injection, the molten material injected into the mold cavity is kept in shape.

2️⃣ Clamping System

The role of the mold clamping system: the effect of the mold clamping system is to ensure that the mold is closed, opened and ejected products. At the same time, after the mold is closed, it provides sufficient clamping force to the mold to resist the cavity pressure generated by the molten plastic entering the mold cavity and prevent the mold from opening seams, resulting in unfavorable status of the product.

The composition of the mold clamping system: the mold clamping system is mainly composed of a mold clamping device, a mold adjustment mechanism, an ejection mechanism, a front and rear fixed template, a movable template, a mold clamping cylinder and a safety protection mechanism.

3️⃣ Hydraulic System

The function of the hydraulic transmission system is to realize the injection molding machine to provide power according to the various actions required by the process, and to meet the requirements of pressure, speed, temperature, etc. required by each part of the injection molding machine.

It is mainly composed of various hydraulic components and auxiliary components, among which oil pumps and motors are the power source of the injection molding machine. Various valves control the oil pressure and flow rate to meet the requirements of the injection molding process.

4️⃣ Electrical Control

The electrical control system and the hydraulic system are reasonably coordinated to realize the process requirements (pressure, temperature, speed, time) and various program actions of the injection machine. It is mainly composed of electrical appliances, electronic components, meters, heaters, sensors, etc.

In summary, the injection molding machine is a very efficient machine. If you want to make plastic toys, choosing a high quality Injection molding machine for plastic toys is very important.
