Abstract
The invention is suitable for the field of automobiles, and provides an automobile floor blanking cover and manufacturing and installing methods thereof. The automobile floor blanking cover comprises a blanking cover body, a plurality of buckles and a hot melt adhesive, wherein the blanking cover body is provided with a circular upper cover and a skirt part of a cylindrical shell; the buckles are distributed radially along the circumference of the skirt part; and the hot melt adhesive is positioned at the top end of the skirt part, and is tightly jointed with the upper cover. The automobile floor blanking cover provided by the invention is sealed by melting the hot melt adhesive, so that a good sealing effect, a reasonable structural design, easiness and practicability are realized.
Description
Technical field
The present invention is applicable to automotive field, relates in particular to a kind of automotive floor panel blanking cover and making thereof, installation method.
Background technology
In the production process of automobile,, can on the vehicle body panel beating, hold some necessary auxiliary holes in order to satisfy the demand of welding, application and total coating process.But the auxiliary hole on these panel beatings is useless or even deletrious in the automotive use process, therefore will use in some suitable production phases and stop up it in complete shutoff.
Simultaneously, in order to satisfy the leakage demand of electrophoresis operation, must on body platform, open several auxiliary holes.Wherein, the auxiliary hole size of being opened is bigger, and diameter so that electrophoresis liquid is spilt from the floor, will use obstruction with in its complete shutoff behind the completion electrophoresis more than 30mm.And, because the floor is very near apart from ground, with the external environment direct contact, just require the floor blanking cover to make with the harder material of quality, want good leak tightness simultaneously.And the penetration-resistant and the leak tightness of existing floor blanking cover are poor, can't well satisfy on-the-road requirement.
Summary of the invention
The embodiment of the invention provides a kind of automotive floor panel blanking cover, and it is poor to be intended to solve the penetration-resistant and the leak tightness that have the floor blanking cover now, can not well satisfy the problem of on-the-road requirement.
The embodiment of the invention is achieved in that a kind of automotive floor panel blanking cover, comprising:
The blanking cover body, it has the circular loam cake and the skirt section of cylindrical shell;
The radially-arranged a plurality of buckles of circumference along said skirt section; And
Be positioned at the top in said skirt section, and the hot melt adhesive that fits tightly with said loam cake.
The embodiment of the invention also provides a kind of method for making of above-mentioned automotive floor panel blanking cover, comprises the steps:
Form the blanking cover body through first mold injection;
Said blanking cover body is put into second mould, inject hot melt adhesive;
With said hot melt adhesive cooling, make said blanking cover body and hot melt adhesive be combined into an integral body.
The embodiment of the invention also provides a kind of installation method of above-mentioned automotive floor panel blanking cover, comprises the steps:
Before the coating baking, the blanking cover body is assembled in the circular auxiliary hole compresses, make said buckle be stuck in the edge of auxiliary hole;
After getting into the baking manufacturing line, baking makes said hot melt adhesive deliquescing, tightly is bonded at said blanking cover body on the auxiliary hole;
After accomplishing baking, be cooled to said hot melt adhesive hardening.
The floor blanking cover that the embodiment of the invention provides uses hot melt adhesive to melt sealing, good sealing effect, and reasonable in design, simple and practical.
Description of drawings

The A-A cross-sectional view of floor blanking cover in Fig. 2-embodiment of the invention;
The decomposing schematic representation of floor blanking cover in Fig. 3-embodiment of the invention.
Among the figure: 1. blanking cover, 11. loam cakes, 12. skirt sections, 2. hot melt adhesive, 3. buckle.
The specific embodiment
As shown in Figure 1, the floor blanking cover in the embodiment of the invention comprises blanking cover body 1, hot melt adhesive 2 and a plurality of buckle 3.
Wherein, blanking cover body 1 comprises loam cake 11 and skirt section 12.
A plurality of buckles 3 are 12 circumference radial distribution along the skirt section.
In embodiments of the present invention, blanking cover body 1 adopts the mode of mold injection molding to process, and the cost that mould drops into is not high, economical and practical.
In embodiments of the present invention, hot melt adhesive 2 also adopts the method for injection moulding to process.
Because blanking cover body 1 is manufactured high conformity, stable performance with hot melt adhesive 2 usefulness mold injections.
In the embodiment of the invention, buckle 3 has a plurality of, and 12 radial circumferences are uniformly distributed with along the skirt section, can guarantee that blanking cover body 1 combines reliably with circular auxiliary hole.
As a preferred embodiment of the present invention, blanking cover body 1 adopts the harder PA6 (nylon) of quality, and its penetration-resistant can be good.
In embodiments of the present invention, the method for making of floor blanking cover is following:
1. form blanking cover body 1 through first mold injection;
In embodiments of the present invention, blanking cover body 1 usefulness PA6 (nylon) mold injection forms.
2. blanking cover body 1 is put into second mould, inject hot melt adhesive, the space of being filled up by hot melt adhesive is exactly the shape of hot melt adhesive 2;
3. with hot melt adhesive 2 coolings, blanking cover body 1 is combined into an integral body with hot melt adhesive 2.
Floor blanking cover in the embodiment of the invention is accomplished in the application production phase and is installed, and installation method is following:
1. the preceding blanking cover body 1 with the embodiment of the invention of coating baking is assembled in the auxiliary hole and compresses, and makes buckle 3 be stuck in the edge of auxiliary hole.
2. after getting into the baking manufacturing line, baking makes hot melt adhesive 2 deliquescing, temperature generally be controlled at 140 ℃-170 ℃, and tightly be bonded at blanking cover body 1 on the auxiliary hole this moment, and hot melt adhesive 2 overflows everywhere, fills up all holes, thereby reaches sealing effectiveness.
3. after accomplishing baking, be cooled to hot melt adhesive 2 hardening, thereby accomplish the installation of blanking cover.
The floor blanking cover that the embodiment of the invention provides uses hot melt adhesive to melt sealing, good sealing effect, and reasonable in design, simple and practical.
Simultaneously, blanking cover adopts PA6 (nylon) injection molded, and penetration-resistant can be good.
In addition, blanking cover and hot melt adhesive are made with mold injection, high conformity, and stable performance, the input die cost is not high, economical and practical.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
