Plastic injection molding machine It is a common plastic processing equipment, which can cool and solidify the molten plastic by injecting it into the mold to form the required plastic products. Is the operation of plastic injection molding machine difficult? Can beginners learn easily? This article will introduce the working principle, operation process and safety precautions of plastic injection molding machine, so as to help readers better understand the operation difficulty of plastic injection molding machine and the situation of novices.

First, let's understand the working principle of plastic injection molding machine. The working principle of plastic injection molding machine is to inject molten plastic into the mold through injection barrel, injection valve, nozzle and other parts. After a certain period of cooling and curing, open the mold to take out the products. In this process, it is necessary to control injection speed, injection pressure, mold temperature and other parameters to ensure product quality and molding effect.

Next, let's take a look at the operation process of the plastic injection molding machine. Generally speaking, the operation process of plastic injection molding machine includes the following steps:

1. Preparations before starting up: check whether all parts of the injection molding machine are in good condition, whether the lubricating oil is sufficient, and whether the circuit is normal, so as to ensure that the machine is in a safe state.

2. Install the mold: install the mold on the injection molding machine, and adjust the position and clearance of the mold to ensure that the mold fits well with the injection molding machine.

3. Heating the mold: heat the mold to an appropriate temperature to ensure the quality of products and molding effect.

4. Injection process: inject molten plastic into the mold, control injection speed, injection pressure and other parameters, and ensure the quality and molding effect of products.

5. Cooling and solidification: during the injection process, the plastic in the mold is cooled and solidified to form the required plastic products.

6. Take out the products: after the injection is completed, open the mold to take out the products and carry out subsequent processing.

When operating the plastic injection molding machine, pay attention to the following safety precautions:

1. Before operation, ensure that all parts of the injection molding machine are in a safe state, the circuit is intact, and the lubricating oil is sufficient.

2. During operation, personal protective equipment such as protective gloves and masks shall be worn to prevent injuries caused by molten plastic splashing.

3. During the injection process, the injection speed, injection pressure and other parameters should be controlled to prevent the machine from overloading and causing safety accidents.

4. When taking out products, tools should be used to prevent hand injuries.

In a word, plastic injection molding machines are difficult to operate and require certain skills and experience. For novices, it takes a period of learning and practice to master the operating skills of plastic injection molding machines. During operation, safety precautions shall be taken to prevent accidents.
