Abstract

A nozzle core assembly capable of changing color rapidly comprises a hot nozzle body, a hot nozzle heating ring, a valve needle, a temperature sensing wire, a nozzle core pressing cap, a nozzle core and a color changing cap, wherein the color changing cap is embedded in the inner wall of an inner cavity at the front end of the nozzle core. The utility model discloses to trade the look cap from the overcoat become to inlay on the inner wall of the inner chamber of mouth core front end in the mouth core, not only simple structure changes the look easily moreover.

Description

Mouth core assembly capable of quickly changing color

Technical Field

The utility model belongs to the technical field of the hot runner mold technique and specifically relates to a can trade mouth core subassembly of look fast.

Background

In the prior art, referring to fig. 1, a nozzle core assembly includes a hot nozzle body, a hot nozzle heating ring, a valve needle, a temperature sensing line, a nozzle core pressing cap, a nozzle core and a color changing cap externally sleeved at the front end of the nozzle core, as can be seen from fig. 1, the color changing cap has a large size, a complex shape, a large processing difficulty, a high material cost, and too many contact surfaces with the nozzle core and a mold, which causes difficulty in installation, the color changing cap is easy to fall off from the nozzle core during installation, and meanwhile, because too many contact surfaces exist, the front end of the color changing cap is difficult to compress, gaps are easily generated between the nozzle core and the color changing cap and between the color changing cap and the mold, so that the color changing is difficult.

Accordingly, the prior art is subject to improvements and enhancements.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims at providing a mouth core component which has simple structure and is easy to change color and can quickly change color.

In order to achieve the above object, the utility model adopts the following technical scheme:

a nozzle core assembly capable of changing color rapidly comprises a hot nozzle body, a hot nozzle heating ring, a valve needle, a temperature sensing wire, a nozzle core pressing cap, a nozzle core and a color changing cap, wherein the color changing cap is embedded in the inner wall of an inner cavity at the front end of the nozzle core.

Preferably, the color changing cap extends out of the mouth core.

Preferably, the color changing cap extends out of the plane of the step of the mold by 0.1 mm.

Compared with the prior art, the beneficial effects of the utility model are that:

due to the adoption of the structural design, the color changing cap is changed from being externally sleeved on the mouth core to being embedded on the inner wall of the inner cavity at the front end of the mouth core, so that the structure is simple, and the color is easy to change.

Drawings

FIG. 1 is a prior art spout core assembly;

FIG. 2 is a schematic sectional structure of the present invention;

fig. 3 is a schematic exploded view of the present invention.

The reference numbers in the figures are respectively: (10) the hot nozzle comprises a hot nozzle body, (20) a hot nozzle heating ring, (30) a valve needle, (40) a temperature sensing wire, (50) a nozzle core pressing cap, (60) a nozzle core, and (70) a color changing cap.

Detailed Description

The invention will be described in further detail with reference to the accompanying drawings:

the embodiments described by referring to the drawings are exemplary and intended to be used for explaining the present application and are not to be construed as limiting the present application. In the description of the present application, it is to be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present application and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular manner, and thus should not be considered limiting. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise. In this application, unless otherwise expressly stated or limited, the terms "mounted," "connected," "fixed," and the like are intended to be inclusive and mean, for example, that there may be a fixed connection, a removable connection, or an integral connection, that there may be a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediary, and that there may be communication between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate. In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature in between. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly above and obliquely above the second feature, or simply meaning that the first feature is at a lesser level than the second feature.

Referring to fig. 1 and 2, the nozzle core assembly capable of changing color rapidly of the present invention includes a hot nozzle body 10, a hot nozzle heating ring 20, a valve needle 30, a temperature sensing wire 40, a nozzle core pressing cap 50, a nozzle core 60 and a color changing cap 70, wherein the color changing cap 70 is embedded on an inner wall of an inner cavity at the front end of the nozzle core 60, and under the condition that the size of the nozzle core 60 is not changed, the color changing cap 70 is changed from being externally sleeved on the nozzle core to being embedded on the inner wall of the inner cavity at the front end of the nozzle core 60, and the color changing cap 70 is smaller in size, simple in shape, easy to process and low in material cost; in addition, the matching of the color changing cap 70 and the nozzle core 60 is simpler, the matching dimensional tolerance of the color changing cap and the nozzle core is easy to ensure, and the color changing cap 70 is not easy to fall off.

The color changing cap 70 extends out of the nozzle core and extends out of the plane of the step of the mold by 0.1mm, so that only the front end of the color changing cap 70 is in contact with the plane of the step of the mold, the color changing cap 70 is guaranteed to be tightly pressed with the nozzle core and the mold, dead corners at the pouring gate are avoided, and color changing is easier.

To sum up, the utility model discloses an aforementioned structural design solves the weak point among the prior art, has simple structure, reasonable in design, characteristics such as easy trade look.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention.
