Description

Technical Field

[0001] The utility model relates to the technical field of nozzle hot runner systems, in particular to a nozzle assembly device capable of automatic assembly and correction. Background Art

[0002] Hot runner systems are widely used in small-batch plastic products with fast product cycles and a wide variety of plastic materials. They can also serve as test molds for large-scale plastic production. These unique market demands require single-nozzle hot runner systems with simple structure, high stability, wide plastic material compatibility, and easy installation and maintenance. These requirements present significant challenges for hot runners. The nozzle plays a key role in the nozzle system, providing a channel for plastic flow under high pressure and also providing the pressure to open and close the gate. From a market perspective, with my country's rapid economic development, consumers are increasingly demanding plastic products, with increasing demands for surface quality, and products are becoming smaller and smaller. Existing nozzle systems are relatively large, which has certain limitations when used in micro-sized products and can no longer meet the market demand for plastic products. These challenges pose new challenges to current hot runner products, and the market urgently needs hot runner manufacturers to provide high-quality, low-energy, and small-sized products to meet these market demands.

[0003] Therefore, it is necessary to design a nozzle assembly device that can automatically assemble and calibrate to solve the above problems. Utility Model Content

[0007] Preferably, the adjustment assembly includes a transverse screw module for controlling the horizontal lateral movement of the adjustment platform and a longitudinal screw module for adjusting the horizontal longitudinal movement of the adjustment platform.

[0008] Preferably, an air cooling pipe assembly is provided in the side panel.

[0009] The beneficial effects of the utility model are as follows: the technical solution enables the nozzle to be assembled quickly and accurately, is simple to install, reduces complicated assembly processes, and directly installs the groove and the jig used in conjunction, thereby effectively ensuring concentricity.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0015] Reference Figures 1 to 2A nozzle assembly device capable of automatic assembly and correction includes a base 1, side panels 2 arranged around the base, an adjustment platform 3 placed on the base, an adjustment component 4 for controlling the adjustment platform, a pressure sensor 5 installed on the adjustment platform 3, a bottom heat insulation plate 6 arranged on the pressure sensor 5, and an assembly mechanism 7 arranged on the heat insulation plate;

[0016] The adjustment assembly 5 includes a transverse screw module for controlling the horizontal lateral movement of the adjustment platform and a longitudinal screw module for adjusting the horizontal longitudinal movement of the adjustment platform;

[0017] The assembly mechanism 7 includes a heat insulation plate 71 arranged around the periphery, a mounting plate 72 arranged inside the heat insulation plate, an outer adjustment block 74 mounted inside the mounting plate via a fixing member 73, an inner adjustment block 76 mounted inside the outer adjustment block 74 via a second fixing member, and a heating block 77 mounted below the inner adjustment block 76 via screws.

[0018] The inner adjustment block 76 is provided with a groove for assembly, and an auxiliary fixture 9 is installed in the groove;

[0019] In order to quickly cool down and ensure the coordination of internal temperature, an air cooling pipe assembly 8 is provided in the side panel 2;

[0020] The heat insulation board 71 wraps the entire assembly mechanism 7, thereby ensuring that the internal temperature is lost and preventing heat from escaping and preventing scalding of the assembly personnel;

[0021] In this embodiment, the assembled product is installed into the auxiliary jig 9. The top is pressed into the jig 9 by a downward pressure assembly or manually. To prevent excessive pressure and determine the assembly's compliance, a pressure sensor at the bottom senses the extrusion force applied during assembly, thereby determining the assembly's compliance or strength. To accommodate products of varying sizes and improve assembly precision, the adjustment platform's adjustment assembly 4 adjusts the X- and Y-axis positions to ensure proper assembly position and adapt to varying apertures. After ejecting the plastic from the injection molding machine nozzle, it flows through the plastic flow channel in the heating body and into the nozzle. The injection frequency is set according to customer requirements, and then flows into the customer's mold cavity for molding. During this process, the air flow in and out of the air path drives the valve pin up and down. The valve pin is mounted on the piston, and when the piston moves, the valve pin also moves relative to the piston, closing and opening the nozzle. A double fluororubber O-ring helps seal, preventing gas leakage and effectively maintaining the required air pressure for piston movement. The valve needle and nozzle are precisely matched, ensuring smooth movement and preventing the needle from getting stuck. They also prevent plastic from escaping and leaking. The high-precision nozzle ensures high-quality sealing. As the valve needle moves up and down, it effectively controls the movement of the needle seal and the frequency of the valve needle's opening and closing, resulting in superior plastic product quality.

[0022] The benefits of the present invention are that the technical solution enables the nozzle to be assembled quickly and accurately, is simple to install, reduces the tedious assembly process, and is directly installed with a groove and a matching fixture, thereby effectively ensuring concentricity.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
