Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method of attaching a sliding body to a metal plate.

Overview> The present invention provides a hole for molding a sliding body made of synthetic resin, and a sliding groove that is provided continuously with the hole and is wider than the hole and has thinner edges on both sides of the sliding direction. At the hole part of the metal plate, a sliding body consisting of a shaft part inserted into the hole and a bulging part wider than the hole and formed at the upper and lower ends of the shaft part is integrated with the metal plate. Provided is a method for attaching a sliding body to a metal plate in which, after molding, the sliding body formed in this integral mold is moved from the hole to the sliding groove so that it can reciprocate within the sliding groove. Moreover, the sliding body can be slidably attached to a metal plate by integral molding very easily.

<Prior art> Fig. 5 shows an example of a synthetic resin body 3 attached to a metal plate work. A synthetic resin body 3 consisting of a swollen part 5 at the upper and lower ends of the part 4 is integrally molded and attached.

FIG. 6 is a diagram for explaining the integral molding method, in which the metal plate 1 having the hole 2 is inserted between the upper and lower molds 6 and 7, and the hole 2 is wider than the hole 2. and recesses 8 formed in the upper and lower molds 6 and 7 so as to communicate with the crest holes.
, 9 shows the so-called outsert molding method, which is performed by pouring a molten synthetic resin material into parts 9 and 9.

<Problems to be Solved by the Invention> However, when the synthetic resin body 3 attached to the metal plate by the above-mentioned integral molding method solidifies from the molten state, it shrinks and adheres tightly to the metal plate. do.

Therefore, the hole 2 is made longer than the synthetic resin body 3 as shown by the two-dot chain line in FIG. Even if you try, the drawback is that you cannot expect smooth sliding movement.

Means to Solve the Problems> By the way, recently there has been a demand for the development of a technology in which a synthetic resin body is slidably attached to a metal plate as a sliding body to operate a switch actuator, etc., for the purpose of making equipment silent. However, as mentioned above, the disadvantage that the synthetic resin body adheres to the metal plate cannot be avoided.

The present invention was invented in view of the drawbacks of such a method of integrally molding a synthetic resin body onto a metal plate, and includes a hole that is used for molding a sliding body and into which the shaft portion of the sliding body is inserted; Continuing with the crest hole, there is a sliding groove for sliding the sliding body, the sliding groove is wider than the hole, and both edges in the sliding direction are made thinner to form a sliding surface. A metal plate is formed, and upper and lower molds each having a recess that is wider than the hole and communicates with the hole are provided, and the hole communicates with both of the recesses between the upper and lower molds. Holding the metal plate as shown in FIG. The sliding body is moved from the hole and positioned in the sliding groove, and the sliding body is slid on the metal plate within the sliding groove along the sliding surface. By providing a method, a sliding body is slidably attached to a metal plate.

<Operation> Therefore, according to the present invention, by moving the sliding body formed in the hole of the metal plate from the hole and positioning it in the sliding groove, the sliding body can be moved in the sliding groove. It can be slid freely with almost no noise and can be used in many machines and devices.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a state in which the sliding body is attached to a metal plate by the attachment method according to the present invention, and the metal plate 11 has holes 12 that are continuous so as to form a straight line with the crest holes 12. There is a sliding groove 13 provided as a closing groove.
3 is slightly wider than the hole 12, and both edges in the sliding direction are formed thin to form sliding surfaces 14 and 14.

portion 16 and the sliding groove 13 at the upper end of this shaft portion 16.
The upper bulging part 17 is formed wider and is slidably placed on the sliding surface 14.14, and the lower part is formed wider than the sliding groove 13 at the lower end of the shaft part 16. Swollen part 1
A slide 11f'15 made of a synthetic resin material and having a cross section of 8 is positioned so as to be able to slide within the sliding groove 13 along the sliding surfaces 14, 14.

In order to attach the sliding body 15 made of synthetic resin material to the metal plate 1 in the above-mentioned state, a molding method called outsert molding method is used as in the past.
Based on the molding method shown in Figures to Figure 4, the lower mold 16
The figure h shows the metal plate 11 inserted between the upper mold 20 and the sliding body 15 integrally molded. In these figures, the lower mold has a fitting hole 17 on its upper surface CC which has a depth equal to the thickness of said metal plate 11 and tightly bottoms said metal plate 11;
A protrusion 18 that is located in the fitting hole 17 and tightly passes through the sliding groove 13;
It has a recess 19 at one end which is deeper than the hole 17, has a length L equal to the length l of the hole 12, and has a width wider than the hole 12; On the lower surface, there is a relief part 21 that closely abuts the protrusion 18 of the lower mold 16, and a protrusion 22 that closely fits into the thinly formed portions of both edges of the sliding groove 13 in the metal plate 11. 23 and the lower mold 16 above
A recess 24 that communicates with the recess 19 and has the same shape and size as the recess 19.
It has

When molding, first insert the metal plate 11 between the two molds 16 and 20 formed as described above, and then insert the metal plate 11 between the two recesses 19 and 24 and the holes in the metal plate 11. By pouring a molten synthetic resin material into the hole 12 through a sprue and a runner (not shown) and solidifying it, the metal plate 11 is formed in the hole 12 as shown in FIGS. 2 to 4 above.
The sliding body 15 made of the synthetic resin material described above can be integrally molded.

Then, after taking out the metal plate 11 integrally molded with this sliding body 15 from both the molds 16 and 20, the sliding body 15 is moved from the hole 12 and as shown in FIG.
3, the installation of the sliding body 15 to the metal plate 11 according to the present invention is completed.

As described above, in the present invention, the sliding body 15 made of a synthetic resin material is attached to the metal plate 11. After the sliding body 15 is positioned in the sliding groove 13 as shown in FIG.
By appropriately filling the spacer 2 with a spacer, the sliding body 15 will not engage with the hole 12 while sliding in the sliding groove 13 and the sliding will be obstructed. Although the grooves 13 are arranged on the same straight line, the arrangement is not limited to this, for example, they may be arranged at right angles, etc., depending on the area of the metal plate, the length of the hole, the sliding groove, and other mounting parts. They may be arranged at any angle in relation to the above.

Effect> Once a sliding body made of a synthetic resin material is attached to a metal plate using the attachment method according to the present invention, the sliding body can be slid freely and silently on the metal plate, so that various effects can be achieved. It can be used for many purposes, and its effects are remarkable.
