Description

[Detailed Description of the Invention] The present invention relates to various plastic molded products that are convenient for installation.

Conventionally, this type of plastic molded product has often been attached to a mounting plate using mounting screws or by preparing a separate mounting tool and fitting it together.

In addition, the functionally devised products had complicated mold structures, which was disadvantageous from an economic point of view.

Furthermore, there are completely fixed types that cannot be removed, and there are also types that are difficult to remove from the mounting surface, but when they are mounted on the surface of a large device, they are extremely complicated to handle.

The purpose of this invention is to fit the mounting plate onto the surface of the mounting plate with a predetermined force and to easily remove it from the surface side again if necessary.
To provide a plastic molded product with mounting notches that does not complicate a molding die.

The plastic molded product with mounting notches according to the present invention has a set of two notches with insertable tips protruding from the inner position of the mounting bottom surface, and when the notches are fitted into the fitting holes of the mounting plate, the fittings are fixed. It is characterized in that the entire bocchi is tilted from the fixed end to the tip so as to press the side part of the joint hole.

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 8 show cross sections of a plastic molded product mounted on a mounting plate in a conventional manner for mounting a plastic molded product of this type.

In FIG. 1, the bottom surface 2 of the plastic molded product 1 has a spherical surface that fits into a predetermined hole 4 provided in the mounting plate 3 at a shoulder 5 so that it can be attached to the mounting plate 8 without any gaps, and furthermore, A mounting notch 7 which has a penetrating angle and a diameter 6 larger than the diameter of the hole 4 of the mounting plate 3 is becoming popular.

A hollow part 8 is provided in the mounting notch 7 so that it can be bent inward when being inserted into the hole 4.

However, in order to mold the hollow portion 8, a slide core is required, and the plastic molding die becomes complicated, which is economically disadvantageous.

In the case of plastic molding using a general mold, after resin filling, the upper and lower two split molds are opened and the cured molded product is taken out. In addition to the upper and lower molds, such as a split mold or a multi-piece mold, the hollow portion 8 cannot be formed unless a side slide core that opens simultaneously with these molds is used.

In Figure 2, the bottom surface 10 of the plastic molded product 9 is attached to the mounting plate 11.
The bottom face 10 has a claw part 18 that engages with a predetermined hole 12 provided in the mounting plate 11 so that the two faces can be attached to each other without any gaps. This is what we are doing.

In order to mold such a plastic molded product 9 without causing damage to the claw part 13 of the botch 14 when the mold is opened, a plastic mold having a side sliding core is used like the molded product shown in FIG. 1. This is necessary and an increase in manufacturing equipment costs cannot be avoided.

Further, the molded product 9 cannot be removed from the front side of the mounting plate 11, and especially in the case of a large device, it is difficult to remove it from the back side.

Figure 3 shows a plastic molded product 16 and a mounting plate 17 that are joined together using a botch 18, and the ends are thickened 1 by heat caulking or the like.
9.

In this case, the plastic molding mold only needs to have two upper and lower molds, which is economical, but there is a major drawback in that once the molded product 16 is attached to the mounting plate 17, it cannot be removed.

FIG. 4 shows an embodiment of the plastic molded product with mounting notches according to the present invention, and shows a perspective view of the previous plastic molded product and the mounting plate.

A set of two U-shaped notches 22 of a predetermined length are provided on the mounting bottom surface 21 of the plastic molded product 20, and the mating mounting plate 2
3 is provided with a hole 24 having a slightly larger diameter than the diameter of the botch 22.

FIGS. 5A and 5B are cross-sectional views of a plastic molded product according to an embodiment of the present invention attached to a mounting plate.

In FIG. 5A, the plastic molded product 20 is a set of two, each having a predetermined length in a U-shape, and has an entry hole 26 at the tip.
The mounting plate 23 is provided with a predetermined hole 24.
Although there is a gap on the inner side, a relief part 25 is provided on the outer side for the purpose of contacting the notch 22 and applying force to push the notch 22 inward, and providing a more effective spring action.

FIG. 5B is the same as FIG. 5A, but the mounting notch 22 is shaped like an inverted letter.

Therefore, contrary to FIG. 5A, the outer surface of the hole 24 of the mounting plate 23 has a gap, and the inner surface provides a force to push the notches 22 outward.

As shown in FIGS. 5A and 5B, plastic molded products with simple column-shaped mounting notches that are highly elastic allow upper and lower mold openings due to the spring action even if the mounting notches are inclined, and slide cores, etc. It is economical because it does not require a complicated mold structure.

As explained above, according to the present invention, the entire set of two botches is provided so as to project from the inside of the mounting bottom surface in an inclined manner from the fixed end to the tip. This action presses the side of the fitting hole on the mounting plate, making it easy to attach and detach to and from the mounting plate just by linear operation from the surface side of the plate. It can be held securely by the joint spring action of the two sets of inclined botches.

Furthermore, simply arranging the bar-shaped bocchi can simplify the mold structure required for molding.
