How to connect cooling water to injection molding machine

 injection molding machine

The method of connecting cooling water:

1. The injection molding machine has two water cooling channels, one is mold cooling and the other is oil cooling.

2. The water inlet pipe is divided into two ways with a tee, and a valve is added to the oil cooler to adjust the water inlet.

3.

Backwater

It can be separated or brought together, and the pipe should be as large as possible to facilitate drainage.

The main molding equipment that uses plastic molding molds to make plastic products of various shapes.

Divided into vertical, horizontal, and all-electric types, the injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it inject and fill the mold cavity.

Working principle of injection molding machine:

The working principle of the injection molding machine is similar to the syringe used for injection. It uses the thrust of the screw (or plunger) to inject the plastic that has been plasticized into the molten state (that is, the viscous flow state) into the closed cavity. The process of obtaining products after curing and setting.

Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding—melt plasticization—pressure injection—mold filling and cooling—mold opening and pick-up. After taking out the plastic parts, the mold is closed again, and the next cycle is carried out.

Injection molding machine operation items: Injection molding machine operation items include three aspects: control keyboard operation, electrical control system operation and hydraulic system operation.

Carry out the injection process action, feeding action, injection pressure, injection speed, selection of ejection type, temperature monitoring of each section of the barrel, adjustment of injection pressure and back pressure, etc.

The adjustment of the process in the production process is a necessary way to improve the quality and output of the product. Since the injection molding cycle itself is very short, if the process conditions are not well grasped, there will be an endless stream of waste products.

When adjusting the process, it is best to change only one condition at a time, and observe several times. If the pressure, temperature, and time are all adjusted together, it will easily cause confusion and misunderstanding. If something goes wrong, you don’t know the reason.

There are many measures and means to adjust the process. For example, there are more than ten possible solutions to solve the problem of product dissatisfaction. Only one or two main solutions to solve the crux of the problem can be selected to truly solve the problem.

Molding Conditions of Injection Molding Machine (Part 2)

 1. Filling pressure In injection molding conditions, filling pressure refers to the pressure to fill the resin into the mold, also known as primary pressure. The unit is MPa or kgf/cm2. That is the unit of pressure. There are also some injection molding machines that set the maximum injection pressure to 100%, and then adjust the injection molding conditions by changing the percentage. (Example: 35%) If the filling pressure is too low, poor filling (underfill) will occur. If the filling pressure is too high, the parting surface may be momentarily opened by the pressure, and burrs may appear around the molded product. Sometimes poor release occurs. 2. Injection speed Injection speed refers to the speed at which molten plastic fills the mold. The unit is mm/s. When considering injection volume per unit of time, it may be stated as "injection rate", in which case the unit is cm3/s. If the injection speed is too slow, filling defects may occur; if the injection speed is too fast...

How to choose the original positioning parts of injection mold custom processing workpiece?

 1. Injection mold custom processing workpiece to plane positioning According to the number of degrees of freedom restricted by the plane, it can be divided into three types: The main support surface restricts the positioning plane of the three degrees of freedom of the workpiece, and is often used for the positioning surface of the workpiece with relatively high precision. The guide support surface is a positioning plane that limits the two degrees of freedom of the workpiece, and is often made into a narrow and long surface. The thrust support surface is a plane that limits one degree of freedom. In order to ensure accurate positioning, the area of the plane is often made as small as possible. 2. Injection mold custom processing workpiece is positioned with a round hole Long pins limit 4 degrees of freedom; short pins limit 2 degrees of freedom. 3. Injection mold custom processing workpiece outside cylindrical surface positioning The positioning datum is the centerline of the out...

2K tooling on Injection molding

 Injection molding is a process that was developed based on microfabrication techniques such as LIGA, but there are of course many other methods. The LIGA process is to first produce a model required for injection molding, which is commonly known as "mold", and then pour liquid plastic into the mold, and finally separate it to form the final required product. For example, some Automotive parts have too many products. Injection mold processing is to add plastic to the mold first, and then the mold is continuously rotated along two vertical axes and heated. The plastic in the mold is gradually and evenly coated and melted and adhered to the entire cavity of the mold cavity under the action of gravity and heat energy. On the surface, it is formed into the desired shape, and it is made by cooling and setting.
