Abstract
The utility model provides a detachable hot sprue special for ultrathin-wall plastic parts. The detachable hot sprue is characterized by comprising a core disposed in a sleeve. A heating coil is arranged outside the core, a beryllium copper tip is arranged at the bottom of the sleeve, the core and the sleeve are in press fit in an axial direction and are in small clearance fit in a radial direction, and the core and the heating coil are in interference fit. The detachable hot sprue has the advantages that the number of parts for assembling the sprue is reduced to four from six; processing technology, procedure and requirement are simplified, processing of a red copper sleeve is omitted, processing period is shortened, and production cost is lowered.
Description
Technical field
The utility model relates to a kind of hot mouth.
Background technology
As shown in Figure 1, hot mouth commonly used is made up of six parts, comprises core body 1, compressing tablet 2, sleeve 3, back-up ring 4, heating collar 5 and overcoat 6.Core body 1 axially adopts the compression type fit system with compressing tablet 2, radially adopts little matched in clearance.Core body 1 adopts interference fit to be connected with sleeve 3, and purpose makes sleeve 3 that core body 1 is tightly wrapped up equably exactly.Sleeve 3 cooperates with back-up ring 4 axial compression formulas, radially adopts little matched in clearance.The mode of sleeve 3 and heating collar 5 employing interference fit, overcoat 6 is little matched in clearance with back-up ring 4.The hot mouth structure of this kind is miscellaneous, and difficulty of processing is high.
Summary of the invention
Thereby the purpose of the utility model provides the hot mouth that a kind of designs simplification reduces difficulty of processing.
In order to achieve the above object, the technical scheme of the utility model has provided the special-purpose hot mouth of a kind of detachable ultra-thin-wall plastic, it is characterized in that: comprise core body; Core body is located in the sleeve; Outside core body, be provided with heating collar, it is sharp-tongued to be provided with beryllium copper at the cover tube bottom, the axial employing compression type fit system of core body and sleeve; It radially adopts little matched in clearance, is interference fit between core body and the heating collar.
Preferably, said core body and said beryllium copper adopt the screw thread fit system of screwing between sharp-tongued.
The utlity model has following advantage:
The first, reduced the number of parts that enough becomes nozzle, changed 4 into by 6 original parts.
The second, oversimplified processing technology, procedure and processing request, saved the processing of red copper sleeve pipe, so the process-cycle shortens, production cost reduces.
Description of drawings
Fig. 1 is existing hot mouth structure sketch map;
The structural representation of the special-purpose hot mouth of a kind of detachable ultra-thin-wall plastic that Fig. 2 provides for the utility model.
The specific embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 2, the special-purpose hot mouth of a kind of detachable ultra-thin-wall plastic that the utility model provides is made up of 4 parts altogether, comprises core body 1, sleeve 3, heating collar 5 and beryllium copper sharp-tongued 7.Wherein, core body 1 is located in the sleeve 3, outside core body 1, is provided with heating collar 5, and be provided with beryllium copper in sleeve 3 bottoms sharp-tongued 7, the axial employing compression type fit system of core body 1 and sleeve 3, and it radially adopts little matched in clearance.Be interference fit between core body 1 and the heating collar 5, purpose is exactly that the heat of heating collar 5 is delivered on the core body 1 to greatest extent.Adopt the screw thread fit system of screwing between core body 1 and the beryllium copper sharp-tongued 7.
The utility model has been simplified the loaded down with trivial details structure of hot mouth, has simple structure, first-class effect.Advantages such as the beryllium copper in the utility model sharp-tongued 7 has the hardness height, and wearability is good, and is anti-corrosion.Heating collar 4 is not fragile, and the heating collar 5 of the hot mouth of this kind is protected in the sleeve 3 fully, certain distance is arranged at interval with sleeve 3, can not produce the situation that heating collar 5 is scrapped because leak glue.
