The utility model discloses, fill the rounded structure that route structure innovation changed into R angle and fill the route and form by ordinary right angle, reduce the filling obstacle among the filling process, reduce the shear heat that forms, improve the product and advance the corresponding regional sun mark defect of point.

Description

Avoid mould runner structure of antenna house product surface solar spot

Technical Field

The utility model relates to the technical field of mold, specifically a avoid mould runner structure of antenna house product surface solar spot.

Background

As communication technology gradually moves from the 1G era to the 5G era, the radome is widely used as a product for protecting the radio frequency unit of the antenna system from the external environment.

Due to the structural characteristics of the antenna housing product, the design of a reverse flow hot runner mold is adopted for most products, the design arranges the filling nozzle from the inner cavity of the product to enter glue, a plastic flow path directly corresponds to the appearance surface of the product in the filling process, and the figure 5 is a schematic structural diagram of the antenna housing product produced by the prior art. Fig. 6 is a partially enlarged structural diagram of B in fig. 5. Fig. 7 is a schematic sectional structure view of C-C in fig. 6. As can be seen from the graph in FIG. 7, an included angle of 95 degrees is formed between the convex point of the antenna housing and the antenna housing product, and the continuous ejection forms shearing heat to cause the temperature of the entering point area to be too high, so that the sun ring mark can appear on the corresponding surface of the entering point, and the quality of a product is influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an avoid mould runner structure of antenna house product surface solar spot to solve the problem that proposes among the above-mentioned background art.

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

the utility model provides an avoid mould runner structure of antenna house product surface solar spot, includes the mould body, is equipped with a plurality of hot runners on the mould body, the hot runner includes the die cavity and the feedstock channel who is linked together with the die cavity, its characterized in that, feedstock channel with the position that the die cavity is bordered is the fillet structure.

More preferably, the fillet structure R is 3.5 mm.

Compared with the prior art, the utility model discloses fill the fillet structure that route structure innovation changed into R angle and fill the route formation by ordinary right angle, reduce the filling obstacle among the filling process, reduce the shear heat of formation, improve the product and advance a little and correspond regional sun mark defect.

Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. 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," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1, a avoid mould runner structure of antenna house product surface solar spot, including the mould body, be equipped with a plurality of hot runners on the mould body, the hot runner includes die cavity 6 and feed channel 4 who is linked together with die cavity 6, feed channel 4 with the position that die cavity 6 borders is the fillet structure. Fig. 2 is a radome product 1 produced by the product of this patent, and the radome product 1 is formed with a convex point 2 at a position corresponding to the glue injection port, i.e. a corresponding position of the gate structure of the mold, in the molding process. The bodies of the radome products 1 with the convex points 2 are in arc transition structures 3. The radius of the circular arc filter structure 3 is preferably 3.5 mm. Preferably, R of the fillet structure is 3.5 mm. The height of the feed channel 4 is preferably 3.5 mm.

This patent has improved the entering point runner, increases the R angle and fills excessively, reduces the shearing heat of filling process, optimizes the regional solar mark defect of runner, effectual improvement product appearance quality, the better quality demand who satisfies the market, this scheme easily promotes and uses on the products of trade field series such as communication, household electrical appliances, car.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
