Fig. 1 shows a product to be produced by a mold apparatus according to the present invention. As shown in the drawing, the parts to be produced in the mold apparatus include a process of cutting a flat base material into a desired shape as shown in (a), a process of bending the outer portion of the flat- And a step of bending the center portion in a Z shape as in (c).

As shown in FIG. 2, the mold apparatus according to the present invention includes a first mold section 10 for performing primary press working, a second mold section 10 for performing secondary and tertiary framing 100). The second mold part 100 is composed of two layers. The second mold part 100 includes a lower mold part 210 for performing secondary processing, and an upper mold part 210, which is provided on the upper part of the lower mold part, (110). It is obvious that the order of processing can not be limited to the above-described order. Since the processing is continuously performed in the upper mold part 110 and the lower mold part 210 of the first mold part 10 and the second mold part 100 by a single stroke in the present invention, It can be said that the parts produced during the third machining can be completed by one stroke.

First, the process (a) in FIG. 1 is performed in the first mold section 10 shown in the left side of FIG. 2. The first mold part 10 includes an upper holder 12a connected to a common plate P connected to the press apparatus and a lower holder 12b held at a constant height on the base B. Punches 14a and 14b are fixed directly below the upper holder 12a through a punch fixing plate 13. [ A die 16 is fixed to the backup die 16a at an upper portion of the lower holder 12b and the backup die 16a is fixed to the lower holder 12b by bolts.

A stopper 11a is fixed to the lower portion of the upper holder 12a by a bolt to provide a stopping function at a bottom dead center and a stop protrusion 11b is fixed to the upper portion of the lower holder 12b by bolts . Therefore, when the common plate P is lowered, the upper holder 12a and the punches 14a and 14b are also lowered. When the common plate P reaches the bottom dead center, the stopper 11a comes into contact with the stop projection 11b.

A guide post 16a for guiding up and down movement is fixed to the upper holder 12a so as to face downward and a guide bush 16a for receiving the guide post 16a and supporting the reciprocating motion is mounted on the lower holder 12b. (17b) are fixed. Further, a built-in guide pin 19 may be further provided to guide the up and down movement of the upper holder 12a.

When the common plate P connected to a press device (not shown) is driven, the upper holder 12a connected to the lower portion moves downward together. It is a matter of course that the punches 14a and 14b fixed to the lower portion of the upper holder 12a may have various shapes depending on the processing form of the material. As the punches 14a and 14b come into contact with the die 16 fixed on the lower holder 12b, the material therebetween is cut as shown in Fig. 1 (a).

The cut material is moved to the second mold part 100 by the operator and processed. Hereinafter, the structure of the second mold part 100 will be described. The second mold part 100 includes the upper mold part 110 and the lower mold part 210 so that the upper mold part 110 and the lower mold part 210 are subjected to two treatments The process almost happens together.

Referring to the upper mold part 110 in the upper part, the common plate P is used together, and an upper holder 112 is supported on the lower part. A punch 114 is fixed to the lower portion of the upper holder 112. An intermediate holder 300 is installed in the middle of the upper mold part 110. The intermediate holder 300 includes an intermediate holder upper part 120 and an intermediate holder lower part 220, which are integrated by bolts Ba.

The upper portion 120 of the intermediate holder 120 may function substantially as a lower holder of the upper mold portion 110 and a die 122 may be fixed on the upper portion of the intermediate holder 120. The die 122 and the punch 114 The material M is processed. The lower part 220 of the intermediate holder is substantially operated as an upper holder of the lower mold part 210. A punch 212 is fixed to the lower part by a bolt Bb. A stripper 214 for supporting the punch 212 is disposed on the lower surface of the middle holder 220. The stripper 214 is fixed to the bottom of the middle holder 220 by a bolt Bc passing through the punch fixing plate 216 And is fixed to the holder lower portion 220.

The base B of the first mold part 10 is commonly used and the lower holder 230 is supported on the base B at a predetermined height. A die 240 is fixed to the upper portion of the lower holder 230 by means of bolts, so that the material is processed between the die 240 and the punch 214 described above.

A cylindrical guide bushing 118 is installed on the upper holder 112 to accurately guide the descent of the upper holder 112 and the lowering of the intermediate holder 300, A guide post 128 is installed to accurately guide the relative up and down movement through the inside of the guide bushing 118. [ A guide post 222 is installed on the lower portion 220 of the intermediate holder 300 and a guide bush 232 is installed on the upper portion of the lower holder 230 to vertically move the guide post 222 upward and downward. Is installed.

The lower holder 230 is kept fixed at a fixed height with respect to the base B, but the intermediate holder 300 is constantly moved in the vertical direction. And the intermediate holder 300 should be returned to the original intermediate position after moving downward. In order to return the intermediate holder 300 to its original position, a gas spring 280 is provided. The lower end of the gas spring 280 is supported by the base B and the upper end of the gas spring 280 is connected to the intermediate holder 300. Therefore, when the intermediate holder 300 moves downward and the downward force of the intermediate holder 300 is released, the intermediate holder 300 is moved to the intermediate position determined by the elastic restoring force of the gas spring 280.

A stopper 126 which is in contact with the stopper 116 is fixed to the upper portion of the upper portion of the intermediate holder 120 by bolts And is fixed to the intermediate holder upper portion 120. Hereinafter, the operation of the mold apparatus according to the present invention having the above-described structure will be described.

When a downward force is applied to the common plate 10 by a pressing device (not shown), the first mold portion 10 cuts the original flat plate material as described above to form a state as shown in Fig. 1 (a) . The processed material is secondarily processed in the lower mold part 210 of the second mold part 100, and then processed in the upper mold part 110 to complete the finished product.

This processing can be said that the first mold portion 10 and the second mold portion 100 are substantially performed by the common plate P which moves up and down substantially by the press device. Hereinafter, the processing performed in the second mold section 100 will be described from the upper mold section 110.

When the common plate P is lowered by the press apparatus, the upper holder 112 and the punch 114 are also lowered. The stopper 116 and the detent projection 126 come into contact with each other. At this time, the punch 114 and the die 122 substantially come into contact with each other, and the processing of the material M therebetween proceeds. The material M between the punch 114 and the die 122 will be completed instantaneously, at which time the gas spring 280 has not yet been compressed. It can be said that the gas spring 280 is lowered after the punch 114 and the die 122 have been processed, and the gas spring 280 substantially supports the intermediate holder 300 until that time.

Subsequently, when the common plate P is lowered, the intermediate holder 300 is lowered, and at this time, the gas spring 280 will also be compressed and contracted. The processing of the material M between the punch 212 fixed on the bottom surface of the lower portion 220 of the intermediate holder 300 and the die 240 supported on the lower holder 230 It happens. When the processing of the material M between the punch 212 and the die 240 is completed, the common plate P is raised by the press apparatus. When the common plate P is raised, the upper holder 112 will be raised accordingly. At this time, the intermediate holder 300 is raised to a predetermined position by the restoring force of the gas spring 280.

The first mold section 10 and the second mold section 100 can be continuously subjected to a single process in a single operation (the operation in which the press apparatus is lowered by pressing the common plate and then raised to the original position) . That is, the first mold section 10, the upper mold section 110 of the second mold section, and the lower mold section 210 of the second mold section operate together by a single press operation to perform predetermined press processing .

Although it is not simultaneous in terms of time, it can be said that press working is continuously performed by three dies by one operation. The upper holder 12a of the first mold part 10 and the upper holder 112 of the second mold part 100 will be interlocked with the lifting and lowering of the press device, 1120 and descends due to the elastic restoring force of the gas spring 280.

The order in which the raw materials are injected and the pressing process is performed is processed into the state shown in Fig. 1 (a) by the processing in the first mold section 10, and then the worker moves the semi-finished product to the second mold section The worker moves the semi-finished product and is finally processed in the upper mold part 110 of the second mold part 100 (c) The product as shown in Fig.

As described above, according to the present invention, since the second mold part 100 having a two-layer structure has a two-layer structure, the third-step machining process can be accomplished by a single stroke in cooperation with the first mold part It is understood that it is a basic technical idea to construct such a structure. It will be understood by those skilled in the art that various other changes and modifications may be made without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. .
