Abstract
Description
Technical Field
[0001] This utility model belongs to the field of injection molding machine nozzle technology, and more specifically, it relates to a novel injection molding machine nozzle for injection molding product production. Background Technology
[0002] Injection molding machine nozzles are plastic spray nozzles that allow plastic to enter the injection machine for fusion processing. They are mainly used for plastic material conveying, nozzle opening and closing, and plastic injection during the injection molding process. Injection molding machine nozzles play a crucial role in plastic processing, and their design and use directly affect the plasticizing quality, injection speed, and the quality of the final product.
[0003] Most existing injection molding machine nozzles adopt a one-piece structure. This design limits the ease of disassembly and poses a challenge to cleaning the inside of the nozzle. During long-term use, various impurities easily accumulate and adhere inside the nozzle. If they are not cleaned in a timely and effective manner, they can easily cause nozzle blockage, affecting production efficiency and product quality. In addition, current injection molding machine nozzles lack an automatic sealing mechanism when not in operation, which may lead to accidental leakage of raw materials from the nozzle opening. Once the raw materials solidify on the outside of the nozzle, it will not only waste materials but may also adversely affect subsequent injection molding operations. Utility Model Content

[0039] The specific usage and function of this embodiment are as follows:
[0040] In this invention, during use, the two sets of nozzle tubes 105 are symmetrically placed outside the fixed cylinder 102 via the limiting groove 106, limiting hole 107, limiting ring 103, and limiting post 104. Then, the locking frame 201 is slidably positioned between the outer sides of the two sets of nozzle tubes 105, and pushed upwards, causing the top of the locking frame 201 to slide between the two sets of fixed seats 108.

When the outer side of the locking frame 201 is in contact with the outer side of the fixed seat 108, the locking block 202 slides inside the locking hole 109 using a spring, allowing the two sets of nozzle tubes 105 to contact the locking frame.

The nozzle tube 105 is fixedly installed in the designated position by the nut 101 and the threaded cylinder 1. When the plastic liquid is sprayed into the nozzle tube 105, the plastic liquid uses hydraulic pressure to push open the sealing block 404, so that the plastic liquid is sprayed out. When the operation stops and the plastic liquid is no longer sprayed out, the spring member uses the vertical column 403 and the baffle 405 to drive the sealing block 404 to reset, so that the nozzle tube 105 port is re-closed. The nozzle tube 105 and its interior can be heated by the electric heating cylinder 302.
