Description

Fasteners for hollow molded articles for vehicles

This creation relates to a fastener for a hollow molded article for a vehicle, and particularly refers to a method for stably holding the fastener on a positioning post in a mold when the fastener is poured into the hollow molded article, so that the fastener does not have Risk of displacement or shedding.

According to the general vehicle accessories, such as car pedals, spoilers, truck bucket guardrails, etc., are mainly made of plastic hollow molding, please refer to the first to third pictures. Most of them are in the process of hollow molding. Several fasteners 1 are poured into the hollow molded object A (as shown in the first figure), and the fastener is used for the hollow molded object A to be used for fastening to the vehicle. It is used to fix the hollow molded object A on the vehicle, and the conventional fastener 1 structure, as shown in the second figure, is mainly made of metal materials, and a perforation 10 is mainly provided in the fastener 1 , The perforation 10 is provided with a buckle ring groove 11, and an outer wall surface of the fastener 1 is provided with a pouring groove 12, so that it is a fastener structure; At this time, as shown in the third figure, the fastener 1 is first set on the end B10 of the positioning post B1 in the mold B, and the end B10 of the positioning post B1 is protruded on the cavity B2 of the mold B Then, the ABS plastic material is injected into the cavity B2 for hollow molding, and the fastener 1 on the positioning post B1 is filled to form a hollow molding. A (such as the car pedal, spoiler, truck bucket guardrail, etc.). However, the conventional metal fastener 1 is set on the positioning column B1 of the metal mold B and cannot be positioned, so it is formed in a hollow shape. During filling, there may be a risk that the fastener 1 will be displaced or dropped off on the positioning post B1, and the fastener 1 cannot be accurately filled in the correct position in the hollow molded object A, which may easily cause the defective product of the hollow molded object A. Moreover, the fastener 1 is made of a metal material, and the manufacturing cost is relatively high.

The purpose of this creation is to provide a fastener for a hollow molded object for vehicles. The fastener can be firmly clamped on a positioning post in a mold, which can effectively solve the problem that the conventional fastener is filled in a hollow molded object. The absence of displacement or shedding that is present.

The fasteners of the hollow molded articles for vehicles are the fasteners used for filling the hollow molded articles for vehicles;
It is characterized in that: a perforation is provided in the fastener, a plurality of clamping claws are protruded on one end surface of the fastener, and a plurality of fastening protrusions are provided in the perforation of the fastener.

The fastener of the hollow molded article for the creative vehicle, wherein the fastener is made of PC material.

In the present invention, a fastener for a hollow molded article is used, in which each of the fastening convex systems of the fastener and each of the clamping jaws are dislocated.

The fastener for a hollow molded article for a creative vehicle, wherein a positioning flange is provided on the outer wall surface of the fastener.

The advantages of the fasteners for the hollow molded objects used in the creation of the vehicle are that the fasteners can be firmly held on the positioning posts in the mold by its clamping claws, so that when the fasteners are filled in the hollow molded objects, the fasteners There is no risk of displacement or falling off on the positioning post of the mold, which can greatly improve the yield of the product and reduce the manufacturing cost in the hollow molding manufacturing.

Regarding the technical means used in this creation to achieve the above-mentioned use purpose and effect, the preferred and feasible embodiments are listed, and the drawings are shown in detail as follows:

The embodiment of this creation, as shown in the fourth figure, is mainly provided with a fastener 2, which is made of PC material. The fastener 2 has a perforation 20 therein, and one of the fasteners 2 Four clamping jaws 21 are protruded on the end surface, and four fastening protrusions 22 are provided in the perforation 20 of the fastener 2. The fastening protrusions 22 are offset from the clamping jaws 21. A positioning flange 23 is provided on the outer wall surface, so that it is a fastener structure for a hollow molded article for a vehicle.

When manufacturing the hollow molding, please refer to the fourth to seventh figures. When the hollow molded object A is filled with the fastener 2, as shown in the fifth and sixth figures, the fastener 2 is first set in the hollow molding mold B. On the end B10 of the positioning post B1, the four clamping jaws 21 on the fastener 2 are clamped on the end B10 of the positioning post B1, and the end B10 of the positioning post B1 is convexly arranged on the mold B. Inside the cavity B2, and then inject ABS plastic material into the cavity B2 for hollow molding. The fastener 2 on the positioning column B1 is filled to form a hollow molded object A (such as a car pedal, a spoiler, a truck bucket fence, etc.) (As shown in the seventh figure), the fastener 2 of this creation is made of PC material, and the clamp 2 on the fastener 2 can be used to firmly hold the fastener 2 to the positioning post in the mold B. B1, and the positioning flange 23 on the outer wall surface of the fastener 2 can be stably positioned in the hollow molding object A, so that during the hollow molding filling, the fastener 2 will not be displaced or dropped off on the positioning column B1. The risk is that the manufacturing yield of the hollow molded article A can be improved, and the manufacturing cost can be reduced.

In summary, this creation has indeed achieved the intended purpose and effect of use, and is more ideal and practical than those who are familiar with it. However, the above embodiment is only a specific description of the preferred embodiment of this creation. This embodiment is not intended to limit the scope of patent application for this creation. For example, all other equivalent changes and modifications made without departing from the technical means disclosed in this creation shall be included in the scope of patent application covered by this creation.
