Haochen VG needle valve hot nozzle is a basic type of needle valve hot nozzle, which is equivalent to the extension of injector nozzle in terms of the first mock examination single hot nozzle. By air pressure orhydraulic pressurePower, controlling the piston to drive the valve needle to open when retracting and close the rubber outlet when extending to inject plastic products.

This is a basic type of needle valve hot nozzle, which is equivalent to the extension of injector nozzle in terms of the first mock examination single hot nozzle. By using pneumatic or hydraulic power, the control piston drives the valve needle to open when retracting and close the rubber outlet when extending to inject plastic products.

Characteristics of VG type hot nozzle:

1. Large diameter gates can be used for large, thin plastic products and laminated cavities that are difficult to injectmouldIt is more applicable and can prevent the phenomenon of plastic material salivation and wire drawing.

2. After injection molding, the surface of the plastic product's injection port only leaves small marks on the front end of the valve needle, making the product smooth and flat.

3. When the injection machine injects glue, the timecontrollerAdjust the action of the valve needle to open and close the glue outlet, which can delay the retraction of the valve needle for glue injection and advance the extension of the valve needle to close the glue injection port. The glue injection sequence can be adjusted to 0.01 seconds.

4. The sequence of opening and closing gates for injection molding can adjust product shrinkage, water marks, burrs, injection difficulties, and deformation issues.

5. The large diameter of the gate makes it easy for fine non melting impurities to be injected and discharged with the rubber material.

6. This type of hot nozzle sealing adhesivebushingDifferent from the material of the body, it has the function of wear resistance and thermal insulation at the sealing point.

7. This type of hot nozzle sealing sleeve is a standard hot nozzle accessory with strong interchangeability and easier compatibility with mold sealing.

8. This type of hot nozzle core has various forms, and its material selection is related to the injection molding of crystalline and amorphous plastics.

9. This type of hot nozzle has a complex structure and high precision in mold installation dimensions,cylinderThe installation and disassembly of oil cylinders require professional personnel to operate.

Haochen VG needle valve hot nozzle is used for single hot nozzle of the first mock examination one cavity plastic products, the first mock examination one cavity plastic products and the first mock examination multi cavity plastic products, which need to be diverted to multiple hot nozzles for multiple rubber inlets through the distributor plate; Due to the appearance of plastic products, large and thin meat products that are difficult to inject, and the use of laminated molds, they can also be suitable for injection molding of most plastic products; The nozzle core style is related to injection molding of crystalline and amorphous plastics; The correct selection of gate diameter is related to the appearance of the product, product structure, and mold structure. Based on the material characteristics, product structure, and mold structure of plastic products, Haochen can provide four mold opening size specifications: VG27, VG32, VG40, and VG50 for customers to choose from. The length of the hot nozzle can be adjusted according to the moldTemplateCustomized size.
