Abstract
The utility model provides a hot-runner tiny nozzle. A nozzle body comprises a core body, a runner arranged in the core body and a nozzle arranged on the head of the nozzle body. The hot-runner tiny nozzle is characterized in that the upper portion of the nozzle body is provided with a nozzle body cap (2). One end of the core body (1), which is close to the upper portion of the nozzle body, is provided with threads. The threads are screwed with the nozzle body cap, and a protective sleeve (5) is arranged on the surface of the core body (1). A heater (4) is positioned between the surface of the core body (1) and the protective sleeve (5), and the heater is provided with a temperature control system. One end of a thermocouple (41) which is arranged inside the heater is connected with the temperature control system, and the other end of the thermocouple (41) is arranged between the core body and the protective sleeve. A nozzle head (3) is arranged at the downmost end of the nozzle body. The hot-runner tiny nozzle has the advantages that the nozzle body is suitable for entering a hot-runner mould with a mold-core open hole limited, and the separating structure of the nozzle head and the core body is in favorable for the installation and the maintenance.
Description
Technical field
The utility model relates to mould manufacturing field, is specifically related to the small nozzle of hot flow path.
Background technology
The injection mold that generally adopts in the injection moulding industry at present is the HOT RUNNER INJECTION MOULD tool, and a typical TOP-TIP is by hot runner manifold, nozzle, temperature controller, and auxiliary component constitutes.Because hot runner mould has the product of shortening molding cycle, saves plastic raw materials, reduces advantages such as percent defective, automated production, is therefore applied to plastics molding process widely.But its shortcoming also is tangible: the accuracy of manufacture of whole system requires high, and particularly nozzle in use breaks down easily and influences production.And when the die perforate of hot runner mould is restricted, nozzle is difficult to enter, the utility model improves nozzle, be fit to enter in the limited mould of die perforate and use, the cap of spraying nozzle head is closed core body split structural design, nozzle is installed be more prone to, keep in repair conveniently, it is more convenient to change.
The utility model content
In order to solve the problems of the technologies described above, adopt following technical scheme:
The small nozzle of hot flow path; comprise core body (1); cap of spraying nozzle (2); nozzle head (3); heater (4); thermocouple (41); protective sleeve (5); the cap of spraying nozzle of nozzle body (2) is connected with core body (1) by screw thread; core body (1) embeds having heaters (4); establish temperature control system in the described heater; shown in heater (4) be provided with thermocouple (41); described thermocouple (41) is located between core body (1) and the protective sleeve (5); temperature to plastics in the runner (11) is responded to; when temperature is lower than setting value; allow heater (41) heat automatically; on core body (1), also be provided with protective sleeve (5), nozzle head (3) be housed in runner (11) the plastics exit of described core body (1).
The utlity model has following advantage: closely spaced hot nozzle is fit to the limited hot runner mould of die perforate, and cap of spraying nozzle head and core body be design separately, and it is more convenient to make to the installation and the maintenance of nozzle.
Description of drawings
Fig. 1 is the small nozzle arrangements schematic diagram of the utility model embodiment hot flow path.
The specific embodiment
As shown in Figure 1; the small nozzle of hot flow path; comprise core body (1); cap of spraying nozzle (2); nozzle head (3); heater (4); thermocouple (41); protective sleeve (5); the cap of spraying nozzle of nozzle body (2) is connected with core body (1) by screw thread; core body (1) embeds having heaters (4); establish temperature control system in the described heater; shown in heater (4) be provided with thermocouple (41); described thermocouple (41) is located between core body (1) and the protective sleeve (5); temperature to plastics in the runner (11) is responded to; when temperature is lower than setting value; allow heater (41) heat automatically; on core body (1), also be provided with protective sleeve (5), nozzle head (3) be housed in runner (11) the plastics exit of described core body (1).
The utility model has the advantages that: nozzle head and core body split structure, it is more convenient that easier installation, maintenance is changed; And the utility model is applicable to the hot runner mould that the die perforate is limited.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvements and modifications of under the prerequisite that does not break away from principle of the present utility model, carrying out, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (1)
1. the small nozzle of hot flow path; nozzle body comprises core body; be located at the runner of core body inside; be located at the nozzle of nozzle head; it is characterized in that: nozzle body top is provided with cap of spraying nozzle (2); core body (1) is provided with screw thread near an end on nozzle body top; described screw thread and cap of spraying nozzle screw; described core body (1) surface is provided with protective sleeve (5); be provided with heater (4) between described core body (1) surface and the protective sleeve (5), described heater is provided with temperature control system, and thermocouple (41) one ends of establishing in the described heater are connected with temperature control system; described thermocouple (41) other end is located between core body and the protective sleeve, and described nozzle head (3) is located at nozzle body bottom.
