Description

Structure for ensuring appearance of sprue

Technical Field

The utility model relates to the technical field of automobile injection molding parts, in particular to a structure for ensuring the appearance of a sprue.

Background

At present, with the rapid development of the automobile part industry, the application of an appearance decorative ring mold is quite wide, the problem that the appearance is adversely affected by trimming of a decorative ring gate also happens occasionally, and a reliable solution is urgently needed to be found. The defects and shortcomings of the prior art are as follows: the common gate is easy to cause that the scissors are difficult to completely trim due to the structural position space limitation, and the residual break difference exceeds the allowable range to cause poor appearance. For example: at present, a plurality of products can be made into appearance and optical dermatoglyph, and some product gates are required to be arranged at the edges of dermatoglyph surfaces, so that appearance defects can be generated due to improper space position limitation treatment.

SUMMERY OF THE UTILITY MODEL

The utility model solves the problems that common gates are difficult to completely trim due to structural position space limitation in the related art, and the residual fault difference exceeds the allowable range to cause poor appearance, and provides a structure for ensuring the appearance of the gates.

In order to solve the technical problems, the utility model is realized by the following technical scheme: a structure for ensuring the appearance of a sprue comprises a product and the sprue which are connected with each other, wherein the sprue is positioned in a straight top, the ejection direction of the straight top is consistent with the mold stripping direction of the product, and the straight top ejects the sprue out of a mold and is forcedly separated from the product.

Preferably, the wall thickness of the product is the same as the wall thickness of the gate.

Compared with the prior art, the utility model has the beneficial effects that: according to the utility model, the sprue is arranged in the straight top, the ejection direction of the straight top is consistent with the mold stripping direction of the product, the straight top ejects the sprue out of the mold and is forcedly separated from the product, namely the straight top ejects the sprue and the sprue is broken without secondary trimming, the production difficulty operation that the sprue is difficult to trim is thoroughly solved, the product percent of pass is increased to 95%, the normal production requirement of a factory is met, the waste of resources is reduced, and the production benefit is greatly improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the utility model, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

The relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be discussed further in subsequent figures.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … … surface," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of the present invention should not be construed as being limited.

As shown in fig. 1 to 7, a structure for ensuring the appearance of a gate comprises a product 1 and a gate 2 which are connected with each other, wherein the gate 2 is positioned inside a straight top 3, the ejection direction of the straight top 3 is consistent with the mold ejection direction of the product 1, and the straight top 3 ejects the gate 2 from a mold and is forcibly ejected out of the product 1.

In one embodiment, the wall thickness of the product 1 is the same as that of the gate 2, so that no cold material exists in the product 1 and the gate 2 can be smoothly removed.

The above embodiments are preferred embodiments of the present invention, and those skilled in the art can make variations and modifications to the above embodiments, therefore, the present invention is not limited to the above embodiments, and any obvious improvements, substitutions or modifications made by those skilled in the art based on the present invention are within the protection scope of the present invention.
