Hot channel hot nozzle bushing heating structure

Abstract

This utility model provides a hot runner nozzle sleeve heating structure, including a nozzle seat, a hot nozzle body at the bottom of the nozzle seat, a heating sleeve fitted on the outside of the hot nozzle body, a heating wire wound around the outside of the hot nozzle body, and the heating wire located between the heating sleeve and the hot nozzle body. A filtering mechanism for filtering raw materials is provided at the top of the nozzle seat. The filtering mechanism includes an assembly sleeve, with fixed holes arrayed at both ends and fixed grooves on both sides. The filtering mechanism can filter the plastic entering the hot nozzle body, preventing particles carried in the plastic from clogging the hot nozzle body, thus avoiding poor or blocked dispensing of glue. This greatly improves the service life of the hot nozzle body and reduces its replacement efficiency. The filtering mechanism and the hot nozzle body are designed separately, and the filtering mechanism can be quickly assembled and disassembled using components such as an assembly frame.

Description

Technical Field

[0001] This utility model relates to a hot runner hot nozzle sleeve heating structure, belonging to the field of mold technology. Background Technology

[0002] Hot runners are heating component systems used in injection molds to inject molten plastic particles into the mold cavity. Hot runner nozzles have advantages such as saving raw materials, shortening the part molding cycle, reducing waste, improving product quality, eliminating subsequent processes, and facilitating automated production.

[0003] Hot runner nozzles have certain limitations in use. When plastic flows into the main channel of the nozzle body, the hot runner nozzle lacks a filtering structure. Particle impurities contained in the plastic can flow into the mold through the nozzle core, causing the nozzle to be easily blocked, which affects the operation and service life of the hot runner nozzle. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hot runner hot nozzle sleeve heating structure to solve the problem mentioned in the background technology that the hot runner hot nozzle lacks a filter structure, causing the nozzle to be easily blocked.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a hot runner hot nozzle sleeve heating structure, including a nozzle seat, a hot nozzle body provided at the bottom of the nozzle seat, a heating sleeve installed on the outside of the hot nozzle body, a heating wire wound around the outside of the hot nozzle body, and the heating wire being located between the heating sleeve and the hot nozzle body.

[0006] The top of the nozzle seat is provided with a filtering mechanism for filtering raw materials. The filtering mechanism includes an assembly sleeve. Fixing holes are arrayed at both ends of the assembly sleeve, and fixing grooves are provided on both sides of the assembly sleeve.

[0007] Furthermore, the nozzle seat has an array of assembly holes on both sides, and a fixed block is arranged in an array on the upper part of the inner side of the assembly sleeve. An assembly ring is inserted into the upper part of the inner side of the assembly sleeve, and a fixed slot is arranged in an annular array on the lower part of the outer side of the assembly ring, with the fixed blocks inserted into the fixed slots one by one.

[0008] Furthermore, the upper inner side of the assembly ring is provided with a ring-shaped array of limiting blocks, the first filter plate is inserted into the inside of the assembly ring, and the outer side of the first filter plate is provided with a ring-shaped array of limiting slots, and the limiting blocks are inserted into the limiting slots one by one.

[0009] Furthermore, a second filter plate is provided at the bottom of the assembly ring, and the second filter plate is located inside the assembly sleeve cavity. An assembly frame is placed above the assembly sleeve, and a feed port is opened at the top of the assembly frame and is connected to the assembly sleeve. Bidirectional screws are installed between the two ends on both sides of the lower part of the assembly frame cavity. Movable sliders are sleeved on both ends of the outer side of the bidirectional screws, and the movable sliders are respectively connected to the two ends of the two C-shaped clamps.

[0010] Furthermore, each of the two C-shaped clamps has an array of clamping pins on one side of its cavity, and each clamping pin is inserted into the assembly hole in a corresponding manner. Both C-shaped clamps have an arc-shaped clamping plate on their tops.

[0011] Furthermore, the inner sides of the two arc-shaped plates are provided with fixed pins arranged in an array in the middle, and the fixed pins are inserted into the fixed holes one by one. The two ends of the inner sides of the two arc-shaped plates are provided with reinforcing arc strips, and the reinforcing arc strips are inserted into the two ends of the two fixed sliding grooves respectively.

[0012] The beneficial effects of this utility model are:

[0013] 1. The filtration mechanism can filter the plastic entering the hot nozzle body, preventing particles carried in the plastic from clogging the hot nozzle body, causing poor glue dispensing or blockage, greatly improving the service life of the hot nozzle body and reducing the replacement efficiency of the hot nozzle body.

[0014] 2. The filter mechanism and the hot nozzle body are designed separately. With the help of parts such as the assembly frame, the filter mechanism can be quickly disassembled and assembled, making it convenient for users to clean the particles intercepted by the filter mechanism and to replace the damaged first filter plate.

[0015] 3. The assembly frame and other parts are well-matched, so that the hot nozzle body can be disassembled and installed at the same time for inspection or replacement when the filter mechanism is disassembled and installed. This solves the problem that the hot runner hot nozzles on the market do not have the function of easy disassembly and assembly, the hot nozzle and the liquid guide plate are fixedly connected and difficult to disassemble, the equipment maintenance and cleaning are time-consuming and labor-intensive, and the disassembly time of the staff is large, which is not conducive to equipment maintenance and cleaning.
