Die Head of Blow Molding Machine
What is die head of blow molding machine?
The die head of extrusion blow molding machine, also known as the mold head, is an important part of plastic blow molding machine. As one of the main equipment of the production of plastic products,the die head is very important part to decide the plastic products’ quality. The die head is the vertical body from the extrusion exit to the top is called the die head.There are two types of mold in use, one is the continuous extrusion die head and the other accumulator type die head.
Die Head
What is the function of die head?
Die head is the main part of sodium extrusion molding, it makes the molten plastic from the extruder from spiral motion into linear motion, and further gradually, produce the necessary forming pressure, to ensure the density of plastic parts, so as to obtain the continuous shape of similar cut shape.
It can meet the processing needs of different products, adapt to the different nature of plastic raw materials, the process requirements of different materials, different flow sizes;
It can control the processing and production of multi-layer plastic products more accurately, precisely control the wall thickness of each layer type embryo and the degree of fit between each layer, and ensure the quality of multi-layer plastic products.
The design of the die head of the storage-type co-extruded hollow blow machine adopts rheological design, which can be well controlled and adapted to high or low extrusion capacity.

What is the extrusion system of blow molding machine?
Extrusion screw:The main part of extrusion screws.Generally, the traditional blow molding machine screw can be divided into three sections: feeding section: plasticizing section, separation section.
Feeding section: It is also called the feeding section. After the plastic is conveyed to the screw, with the rotation of the screw, the friction force of the barrel and the screw is used to push the plastic to the front for compaction. During this time, the plastic is solid.
Plasticizing section: The purpose of this step is to further compress the plastic and flatten it hard! Melt it into a liquid again.
The plastic comes from the feeding section to the plasticizing section, and is blocked by the screw groove, filter screen, splitter plate, and machine head to form high pressure, and the raw material is further compacted. At the same time, the temperature in the barrel is continuously raised and becomes liquid due to the rotation and mixing of the barrel and the screw. But at this time, part of the plastic body is still solid, and the plastic slowly squeezes forward to the end of the screw. Due to the action of frictional heat, the temperature at the end of the screw is the highest. When the plastic reaches the end, it has already turned into a viscous fluid state. This is the plasticizing process. It is very important in the screw action of blow molding machine.
Separation section: It is for the plastic to be further plasticized after entering the homogenization section, and then extruded from the screw by means of constant pressure, quantitative, and constant temperature.
It is very important for the separation section in the production process, because the discharge speed of the entire melting section determines the production efficiency of the separation section. In order to achieve a faster discharge speed, an expansion section is added in addition to the three sections, installed in the plastic Between the chemical section and the separation section, the extrusion volume is larger in order to increase the production speed of the separation section.
According to the requirements of plasticizing quantity, the design of different screw length-diameter ratio, the general length-diameter ratio is 24:1, also 28:1.
