Description
Technical field
The utility model relates to injection mold field, and in particular, the utility model relates to a kind of casting of metals molding heater.
Background technology
At present, as an advanced injection molding technology-Hot runner Technology, the mid-term of eighties of last century can be traced back to even more early in the universal use of American-European countries.Because hot flow path has many advantages, therefore, development ratio is very fast abroad, the mould more than 70% that many plastic mould factories produce have employed Hot runner Technology, part mould factory even reaches more than 90%, and in China, and this technology to be just really promoted in recent years and to apply.Along with the development of China's die industry and China's mould fast-developing to the export volume of American-European company; the ratio that hot flow path uses in China's plastic mould is also more and more higher; the heating of hot-runner nozzle generally all adopts heating collar to heat; this heating collar is uneven due to manufacture craft and wound form; often have heating uneven, the problems such as instability occur.Especially to the hot flow path of multi-cavity mold, the uniformity of heating and stability seem particularly important.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of casting of metals molding heater.
For realizing above object, the technical solution of the utility model is a kind of casting of metals molding heater, comprises heating collar, it is characterized in that, described heating collar outer cover is provided with heating casing, and described heating casing is fixedly connected with heating collar.Outside heating collar, cast one deck heating casing, as the intermediary of heating collar and nozzle, make heater have good thermal conductivity, uniformity and the stability of its heating also improve greatly.And it is not heating collar has the protection of heating casing to too increase its service life, fragile.
As preferably, described heating collar comprises heating collar portion and connecting portion, and described heating collar portion comprises foundation ring and collar, is provided with connecting rod between described foundation ring and collar, and described connecting rod is fixedly connected with collar respectively at foundation ring.Form a cylindric heater coil portion by foundation ring, collar, mesosphere, connecting rod, heater coil portion all has heating function in axis, radial direction, makes the heating of heater more even.
As preferably, described foundation ring and collar are equipped with towards consistent opening.
As preferably, be provided with at least one mesosphere between described foundation ring and collar, described mesosphere is provided with foundation ring and collar opening towards consistent opening.
As preferably, described heating collar comprises heating collar portion and connecting portion, described heating collar portion comprises multiple U-shaped circle, the bottom of connecting portion upwards extends to form the first U-shaped circle, and the second U-shaped circle that U-shaped circle is oppositely arranged with first is extended to form downwards at top, between described first U-shaped circle and the second U-shaped circle, form at least one shape is U-shaped mesosphere.
As preferably, described heating casing is provided with and passes through mouth, and described with foundation ring and collar opening pass through mouth towards with described passing through described in the passing towards the consistent or described first U-shaped axis enclosing bottom circular arc of mouth, facilitate processing and manufacturing.
As preferably, described heating casing is provided with hold-down screw, and described hold-down screw is fixedly connected with heating casing.Hold-down screw rotates for limiting heating collar.
The utility model has following beneficial effect: outside heating collar, cast one deck heating casing, as the intermediary of heating collar and nozzle, makes heater have good thermal conductivity, and uniformity and the stability of its heating also improve greatly.And it is not heating collar has the protection of heating casing to too increase its service life, fragile.
For above-mentioned and other objects, features and advantages of the present utility model can be become apparent, preferred embodiment cited below particularly, and coordinate accompanying drawing, be described in detail below.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation that the utility model embodiment one provides;

Fig. 3 is a kind of structural representation of the heating casing that the present embodiment one provides.
1, heating collar, 2, heating casing, 21, pass through mouth, 3, hold-down screw, 4, connecting portion, 5, heating collar portion; 51, collar, 52, foundation ring, 53, mesosphere, 54, connecting rod, 55, opening.
Detailed description of the invention
Below in conjunction with specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described:
Embodiment one
Casting of metals molding heater is (see accompanying drawing 1, 2, 3), comprise heating collar 1, described heating collar 1 outer cover is provided with heating casing 2, described heating casing 2 is fixedly connected with heating collar, described heating collar 1 comprises heating collar portion 5 and connecting portion 4, described heating collar portion 5 comprises foundation ring 52 and collar 51, connecting rod 54 is provided with between described foundation ring 52 and collar 51, described connecting rod 54 is fixedly connected with collar 51 respectively at foundation ring 52, described foundation ring 52 and collar 51 are equipped with towards consistent opening 55, a mesosphere 53 is provided with between described foundation ring 52 and collar 51, described mesosphere 53 is provided with foundation ring 52 and collar 51 opening towards consistent opening 55, described heating casing 2 is provided with and passes through mouth 21, described pass through mouth 21 towards with foundation ring 52 and collar 51 opening towards consistent opening 55, described heating casing 2 is provided with hold-down screw 3, described hold-down screw 3 is fixedly connected with heating casing 2.
Outside heating collar, cast one deck heating casing, as the intermediary of heating collar and nozzle, make heater have good thermal conductivity, uniformity and the stability of its heating also improve greatly.And it is not heating collar has the protection of heating casing to too increase its service life, fragile, heating casing has and passes through mouth, make this heater to install on nozzle more easily, do not worry that heater cartridge does not get on.And heater wire and temp.-sensing wire also can be arranged in this groove, giant putting hole need not be added again to wear heater wire and temp.-sensing wire on mould.When especially a nozzle having multiple heater, the line of institute's having heaters can wear out from this groove.Which reduces the space that nozzle takies, make mould can do compacter.
Embodiment two
Embodiment is with embodiment one and change substantially identical, and difference is: heating collar comprises heating collar portion and connecting portion.Heating collar portion comprises multiple U-shaped circle, the bottom of connecting portion upwards extends to form the first U-shaped circle, and the second U-shaped circle that U-shaped circle is oppositely arranged with first is extended to form downwards at top, between the first U-shaped circle and the second U-shaped circle, form at least one shape is U-shaped mesosphere.And heating casing is provided with and passes through mouth, the axis of the first U-shaped circle bottom circular arc pass described in pass through mouth.In the present embodiment, heater coil portion comprises three U-shaped coils.But the utility model is not limited in any way this.
Although the utility model discloses as above by preferred embodiment; but and be not used to limit the utility model; anyly know this those skilled in the art; not departing from spirit and scope of the present utility model; can do a little change and retouching, therefore protection domain of the present utility model is when being as the criterion depending on claims scope required for protection.
