Technical Field

[0001] This invention relates to molds and mold plates. Background Technology

[0002] The stamping machine includes a die plate. The die plate contains a die. An example of a conventional parting die is shown in Patent Document 1.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2011-136348 Summary of the Invention

[0004] The problem the invention aims to solve

[0005] In parting molds, assembly errors can occur when the elements constituting the mold are joined together.

[0006] Solution for solving the problem

[0007] The mold involved in this invention includes a diamond sintered body, an integral structure, and a side surface, wherein the side surface includes an inclined surface.

[0008] Because it incorporates a one-piece structure, it helps to improve the accuracy of stamping processes. The movement of the die plate relative to the main body is restricted in two orthogonal directions.

[0009] In one example of the mold, an adhesive preparation section for preparing the adhesive is also included.

[0010] The mold and the main body of the board are firmly joined by the adhesive applied to the adhesive application section.

[0011] The mold plate involved in this invention includes a plate body and a mold pressed into the plate body, the mold including a diamond sintered body and an integral structure.

[0012] The die has a one-piece structure, which helps to improve the accuracy of the stamping process. The die is pressed into the sheet metal body, thus securing it firmly to the sheet metal body.

[0447] (Third Implementation)

[0448] In the third embodiment, an example of a method for manufacturing the mold plate 10 of the first or second embodiment is shown.

[0449] The manufacturing method of the mold plate 10 includes, for example, main body related processes, mold related processes, and mold fixing processes.

[0450] The main body-related processes include the processes for manufacturing the main body 100.

[0451] The mold-related processes include the manufacturing processes for mold 300.

[0452] The mold fixing process includes the process of fixing the mold 300 relative to the plate body 100.

[0453] The main related processes include, for example, processes S11 to S14.

[0454] In process S11, the initial state of the plate body 100 is manufactured.

[0455] The initial state of the plate body 100 does not include the recess 210 and the through portion 120.

[0456] Process S12 is performed after process S11.

[0457] In process S12, a recess 210 is formed in the main body 100 of the plate.

[0458] The recess 210 is formed, for example, by wire electrical discharge machining.

[0459] An inclined surface P is formed on the side 232 of the recess 210.

[0460] Process S13 is performed after process S12.

[0461] In process S13, a lower hole of the through hole 122 is formed in the portion of the plate body 100 corresponding to the through portion 120.

[0462] The lower hole of the through hole 122 is formed, for example, by fine-hole electrical discharge machining.

[0463] Process S14 is performed after process S13.

[0464] In process S14, a through hole 122 is formed in the portion of the plate body 100 corresponding to the through portion 120.

[0465] The through hole 122 is formed, for example, by enlarging the lower hole of the through hole 122 using wire electrical discharge machining.

[0466] The diameter of the through hole 122 is set such that when the through hole 342 of the mold 300 is formed by wire EDM, the wire does not interfere with the board body 100.

[0467] Through hole 122 and through hole 342 have, for example, the relationship shown below.

[0468] The through hole 122 projected onto the first reference plane is called the "first projection view". The through hole 342 projected onto the first reference plane is called the "second projection view". The second projection view overlaps with the first projection view. The outline of the second projection view does not overlap with the outline of the first projection view.

[0469] Mold-related processes include, for example, processes S21 and S22.

[0470] In process S21, a substrate comprising a diamond sintered body is formed.

[0471] Process S22 is performed after process S21.

[0472] In process S22, a mold 300 is formed from a substrate including a diamond sintered body.

[0473] Mold 300 is formed, for example, by wire electrical discharge machining.

[0474] A parallel surface Q1 and an inclined surface Q2 are formed on the side 313 of the mold 300.

[0475] The mold fixing process includes, for example, processes S31 to S34.

[0476] In process S31, the mold 300 is pressed into the recess 210 through the side opening 242 of the plate body 100. A pressing fixing part 410 is formed on the mold plate 10. The mold 300 is fixed to the plate body 100.

[0477] Process S32 is performed after process S31.

[0478] In process S32, the bonding and fixing part 420 is formed. The mold 300 is fixed to the plate body 100 through the bonding and fixing part 420.

[0479] Process S32 includes, for example, processes S32A to S32C. Processes S32A to S32C are performed on each of the adhesive fixing parts 420A and 420B.

[0480] In process S32A, adhesive 440 is applied at specified positions on the longitudinal side of the plate body 100 and the longitudinal side of the mold 300.

[0481] Figure 25 An example is shown where adhesive 440 is positioned in a designated location. Adhesive 440 is indicated by a double-dotted line.

[0482] The specified position is, for example, defined as covering the boundary between the longitudinal side of the plate body 100 and the longitudinal side of the mold 300, as well as the groove 350.

[0483] Operation S32B is performed after operation S32A.

[0484] In process S32B, the adhesive 440 present outside the arrangement space 431 of the bonding and fixing part 420 is removed.

[0485] Figure 26 This shows the state after the external adhesive 440 has been removed.

[0486] The external adhesive 440 is removed, for example, by wiping.

[0487] Process S33 is performed after process S32.

[0488] In process S33, a lower hole of the through hole 342 is formed in the part of the mold 300 corresponding to the through portion 340.

[0489] The lower hole of the through hole 342 is formed, for example, by fine-hole electrical discharge machining.

[0490] Process S34 is performed after process S33.

[0491] In process S34, a through hole 342 is formed in the part of the mold 300 corresponding to the through portion 340.

[0492] Through hole 342 is formed, for example, by enlarging the lower hole using wire electrical discharge machining.

[0493] In the wire electrical discharge machining process S34, the wire is configured to pass through the lower hole of the through hole 342 and the through hole 122 of the plate body 100.

[0494] (Effect)

[0495] According to various implementation methods, the following effects can be obtained, for example.

[0496] In one example of mold plate 10, mold 300 includes a diamond sintered body and an integral structure.

[0497] Because it includes a diamond sintered body, the die 300 is not easily worn. Its one-piece structure also helps to improve the precision of the stamping process.

[0498] In one example of mold plate 10, the side surface 313 of mold 300 includes inclined surface Q2.

[0499] The movement of the mold 300 relative to the plate body 100 is restricted in both the lateral and vertical directions.

[0500] In one example of mold plate 10, the recess 210 of the plate body 100 forms a dovetail groove.

[0513] The range of electrical discharge machining techniques that can be used to form the through hole 342 has been broadened. For example, the lower hole of the through hole 342 can be formed by fine-hole electrical discharge machining, and the through hole 342 can be formed by wire electrical discharge machining.

[0514] In one example of mold plate 10, the inclination angle TP of the recess of plate body 100 is included in the range above the first inclination angle of the recess.
