理方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a decorative and protective molding used on the side surface of an automobile body, and more particularly to a method for processing the end of the molding.

されている。(Prior Art) In recent years, various types of plastic extrusion molded products have been used as moldings for vehicles, and among them, in order to reduce weight, there are products made of a non-foamed layer on the outside and a foamed layer on the inside, or products made entirely of foam. Many things are used.

ためそのドア幅等に応じて押出成形品を切断し、
端末処理を施して使用する必要がある。 Since it is preferable in terms of design to arrange this molding in a substantially straight line from the front to the rear of the vehicle body, extrusion molded products are often used because it is easy to obtain a constant cross-sectional shape as described above. However, since the car body has opening/closing parts such as doors, the extrusion molded product is cut according to the width of the door etc.
It is necessary to perform terminal processing before use.

着力が得られないきらいがある。 By the way, as one method of terminal processing,
No. 54-3156, it has been proposed to injection mold a terminal cap in a predetermined mold and integrally attach the terminal cap to a molded terminal. If the entire molding body is made of foam, during injection molding of the terminal cap, the end face of the molding terminal will be temporarily dented by the injected resin pressure, and the resin pressure will be released after molding. As a result, the dent on the end face of the molding is restored, and a bulge often occurs in the molded cap. Therefore, in order to prevent this bulge, JP-A-55-114542 proposes an integral molding method for the terminal cap in which the cut surface of the molded terminal is substantially covered with a mold member, and no resin pressure is applied to the cut surface. has been done. However, in this case, the bonding area between the molded terminal cap and the end surface of the molding is limited to a width that is approximately equal to the outer circumference of the molding terminal, so sufficient adhesion force cannot be obtained between the terminal cap and the molding terminal. I don't like it.

ある。(Problems to be Solved by the Invention) Therefore, the present invention provides a method for processing a molded terminal in which a terminal cap is integrally molded on a molded terminal by injection molding, which does not cause bulges on the outer surface of the terminal cap. The object of the present invention is to provide a novel method for processing a molded terminal that can provide sufficient adhesion strength between the molded terminal cap and the molded terminal.

末に固着するところにある。(Means for Solving the Problems) The gist of the present invention is to provide a molded terminal in a mold having a cavity for the terminal cap, and mold the terminal cap by injecting molten resin into the cavity. At the same time, in the molding terminal processing method in which the cap is integrally fixed to the molding terminal, a protrusion is erected on one cavity surface of the mold, the opposing surface facing the molding end surface substantially covering the center part of the molding end surface. As a result, a cap cavity having a lumen is formed, and a gap communicating with the cap cavity is formed between the opposing surface of the protrusion and the end surface of the molding, and is injected when molding the terminal cap. The cavity for the terminal cap and the gap are filled with molten resin to form the terminal cap, and the cap is fixed to the molded terminal by the molten resin filling the gap.

ものとなる。(Function) Since the present invention is configured as described above, the molten resin injected into the mold (cavity) forms the terminal cap, and the molten resin filled in the void forms the terminal. The cap is fixed to substantially the entire surface (end surface) of the molding terminal, and the bonding area between the molded terminal cap and the molding terminal covers substantially the entire cut end surface of the molding. Therefore, the attachment of the terminal cap to the mall terminal becomes extremely strong.

とは殆ど防止しうることとなる。 On the other hand, as mentioned above, in the mold, a protrusion that defines the inner cavity (inner shape) of the cap is erected on one molding surface with a gap between it and the end face of the molding end, so that the melt that fills the gap Even if the resin is filled so as to compress the end face of the molding, the bulge caused by the restoration of the end face of the molding after molding will cause the bulge to bulge into the inner cavity of the molded terminal cap, and this effect will hardly be reflected on the outer surface of the cap. It is possible.

もよいものである。(Effects) When the terminal cap 50 is integrally molded on the molding terminal 11 in this way, the center of the molding end face 12 is compressed by the void filling resin 52 connected to the terminal cap 50 as described above. Since the molding is done by molding, a dent is temporarily created on the surface, but the molded end surface 12 is connected to the terminal cap 5 through the resin 52 that fills the above-mentioned void.
0, the bulge caused by the restoration of the molding end surface 12 due to the compression also bulges into the terminal cap inner cavity 53 as shown by the broken line in FIG. Most of these are preventable. On the other hand, the terminal cap 50 molded onto the molding terminal 11 is fixed to substantially the entire surface of the molding end face 12 by the resin 52 filling the void 40, and its fixing force is several times that of the conventional method. It was something that could be made into something.
Further, even if the terminal cap inner cavity 53 is provided with the rib 51, the rib 51 is arranged in a thin plate shape or a bent shape, so that the deformation effect due to the restoration of the molding end surface 12 is also affected by the deformation of the rib 51. As a result, the cap 50 was absorbed and molded with almost no effect on the outer surface of the cap 50. In the above description, an example in which the protrusion was provided on the lower die was explained, but the molding terminal may be turned upside down and the protrusion or the like may be provided on the upper die.

末の処理方法。1. A method for processing a molding terminal, in which a molding terminal is installed in a mold having a cavity for the terminal cap, and a terminal cap is molded by injecting molten resin into the cavity, and at the same time, the cap is integrally fixed to the molding terminal. By erecting a protrusion on one cavity surface of the molding die, the opposing surface facing the molding end surface substantially covers the center portion of the molding end surface, thereby forming a cap cavity having an inner cavity, and also forming a cap cavity with an inner cavity. A gap communicating with the cap cavity is formed between the opposing surface and the end face of the molding, and the molten resin injected during molding of the terminal cap is filled into the terminal cap cavity and the gap.
