An injection molding machine with an easy-to-change nozzle

Abstract

This utility model provides an injection molding machine with an easy-to-replace nozzle, belonging to the field of injection molding machine technology. It includes a connecting assembly, which comprises a damage-resistant column located at the bottom of a drive power supply. The bottom of the damage-resistant column has a first outward expansion plate, and a rotating shaft is rotatably mounted on the outer side of the first outward expansion plate. An arc-shaped plate is located at the other end of the rotating shaft. A material conveying pipe is located at the bottom of the drive power supply. A quick-release assembly is located at the bottom of the connecting assembly. The damage-resistant column serves as the main support structure. The first outward expansion plate at the bottom is connected to the arc-shaped plate via the rotating shaft, allowing the arc-shaped plate to rotate flexibly around the rotating shaft. When the nozzle is installed, the damage-resistant column aligns with the nozzle, and the arc-shaped plate is compressed and rotates outward, compressing a spring. After the snap-fit ​​position is aligned, the spring pushes the arc-shaped plate back to its original position and embeds it into the corresponding slot of the nozzle, achieving a quick and secure connection between the nozzle and the drive power supply. The material conveying pipe at the bottom of the drive power supply passes through the damage-resistant column.

Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to an injection molding machine with an easy-to-replace nozzle. Background Technology

[0002] Injection molding machines are key equipment in plastic processing. They can heat and melt granular plastic, then extrude it into a mold cavity through a screw. After cooling and solidification, they are made into various plastic parts or products. They are widely used in industries such as automobiles, electronics, and daily necessities. They can efficiently realize the mass production of plastic products and are of great significance for improving production efficiency and product precision.

[0003] Existing injection molding machines present numerous inconveniences when replacing nozzles. The connection structure between the nozzle and the machine body is complex, requiring multiple tools for disassembly, which is time-consuming and labor-intensive. Installation requires high precision, and manual operation is prone to misalignment, leading to material leakage or unstable injection quality. The replacement process also requires machine shutdown for debugging, affecting production efficiency. Furthermore, some models have limited space for nozzle disassembly, making operation difficult and increasing the labor intensity of workers. Frequent disassembly can also cause wear on the interface, shortening the service life of the equipment.

[0004] Therefore, this application provides an injection molding machine with an easy-to-replace nozzle to meet the requirements. Utility Model Content
