3 is a state diagram of a spring pad made of a molding die according to the present invention.

As shown in FIG. 3, the spring pad manufactured by using the mold of the present invention includes a pad body, a hollow part, a spring seating part, a spring release preventing device, and a mounting groove.

The pad body 10 is formed to fit the top and bottom of the spring plane. Spring pad of the present invention is formed in a circular shape to match the coil spring of the circular plane. A hollow portion 11 is formed in the center of the pad body to match the circular coil spring.

On one side (lower side in the drawing) of the pad body, a spring seating portion 12 is formed with a recess and a spring is seated. At least one spring escape prevention part 13 is formed at a boundary between the spring seating part and the pad body. A part of the spring release prevention part is connected to the pad body and the other part is located outside the spring seat to prevent the spring from being separated from the spring seat.

On the other side of the pad body (upper side in the drawing), a plurality of grooves are formed in the mounting grooves 14 so that the pad body is mounted on the other member of the shock absorber.

The spring pad formed as described above is fitted to the upper and lower parts of the spring in the shock absorber of the vehicle and is mounted on the other peripheral member of the shock absorber so that the spring pad fixes the spring to the shock absorber.

The molding die of the spring pad according to the present invention includes an upper mold, a lower mold, and a cylinder as shown in FIG. 4. An upper mold is movable on the upper side of the lower mold, and a cylinder part is installed on the lower side of the lower mold to move the piston.

The upper mold 100 is located on the upper side of the mold of the present invention to mold the top of the spring pad. The mold for molding the spring pad is divided into upper and lower molds to form upper and lower shapes of the spring pad, respectively. The upper part of the spring pad is molded by the upper mold.

The upper mold 110 and the hollow molding part 120 is formed in the upper mold to mold the upper side and the hollow part of the spring pad. As shown in Figure 3, the mounting groove is formed in the upper side of the spring pad a plurality of grooves, the hollow portion is formed in the center on the plane of the spring pad.

The inner side of the upper mold is formed on the upper side of the pad to form the upper end portion of the mounting groove and the rounded shape of the spring pad. The hollow molded part protrudes downward from the center of the pad upper molded part. The protruding hollow molding portion is in close contact with the center portion of the pad lower molding portion described later to form the hollow portion of the spring pad.

In the mold of the present invention, a plurality of upper and lower molds are formed in one mold, and at the same time, spring pads are formed by the number of upper and lower molds. An injection hole penetrating from the upper side of the upper mold to the upper portion of the pad is formed to inject a melt into each upper and lower mold.

The lower mold 200 is located below the upper mold to form the lower portion of the spring pad. The lower mold of the mold divided into upper and lower parts for forming the spring pad forms the lower shape of the spring pad.

In the lower mold, the pad lower molding part 210 and the seating part molding part 220 are formed to mold the lower side of the spring pad and the spring seating part. As shown in FIG. 3, a spring seating recess is formed at a lower side of the spring pad, and a spring release preventing device is formed toward the spring seating portion at the boundary of the pad body and the spring seating portion.

The inner side of the lower mold is formed with a lower side of the pad to form a spring release prevention and the lower end of the spring pad. The pad lower side molding part is formed in the shape which does not consider the hollow part of a spring pad. In order to mold the hollow part, the hollow molding part is in close contact with the central part of the pad lower molding part during the molding of the spring pad to form the hollow part of the spring pad.

At the edge of the pad lower mold portion, a seat portion molding portion is formed to mold the spring seat portion. On one side of the pad lower molding portion, the piston moving hole 230 is formed to penetrate downward, and the piston is moved up and down. In the present invention, the piston moving hole is formed through the inside of the seat forming portion.

The cylinder part 300 is located at the lower side of the lower mold to pull out the molded spring pad to the upper side. The cylinder portion includes a cylinder body 310 and a piston 320.

One end of the piston is movably located inside the piston moving hole in the lower portion of the pad lower portion, and the other end of the piston is connected to the cylinder body. The piston is formed in the cylinder body so that hydraulic pressure or pneumatic pressure is applied from the outside.

When the spring pad is formed, the piston contracts to the cylinder body and is located inside the lower side of the pad lower molding part. When the spring pad is taken out, the piston is extended from the cylinder body to protrude outward from the inside of the pad lower molding part to remove the molded spring pad. Let's do it.

Looking at the operation of the molding die for the spring pad according to the present invention made as described above are as follows.

5 is a spring pad manufacturing process of the spring pad molding mold according to the present invention.

First, the upper and lower molds are coupled to each other while the piston is positioned inside the piston moving hole (FIG. 5 (a)), and the melt is injected into the upper and lower molds (FIG. 5 (b)), and the upper mold is spaced upwardly from the lower mold (FIG. 5). (c)) and then the piston is moved upward to pull out the molded spring pad (Fig. 5 (d)).

As shown in FIG. 5 (a), the piston of the cylinder portion is moved downward from the cylinder body so that the piston is located inside the piston moving hole without protruding into the pad lower molding portion. The upper and lower molds are combined to prepare the spring pads by aligning the upper and lower pad parts. At this time, the hollow molding part is brought into close contact with the pad lower molding part so that the hollow part is molded properly.

Then, as shown in FIG. 5 (b), the melt is injected into the upper mold portion of the upper mold through the injection hole. The melt is tightly injected into the space between the pad upper mold part and the pad lower mold part.

Then, as shown in Figure 5 (c) the melt is injected into each of the molding portion after a predetermined time elapses the upper and lower molds. The upper and lower molds are dismantled by moving the upper mold upward from the lower mold.

Then, the piston of the cylinder portion is moved upward from the cylinder body as shown in FIG. The piston, which is moved upward along the piston moving hole, protrudes from the lower side molding part and draws out the molded spring pad. The piston of the cylinder part is installed in the lower mold and protrudes outward from the pad lower molding part, so that the product can be taken out more quickly and easily in the molding of the spring pad.

As described above and described with reference to a preferred embodiment for illustrating the principle of the present invention, the present invention is not limited to the configuration and operation as shown and described as such. Rather, those skilled in the art will appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
