Definitions
- the mold setting temperature is often 100 ° C. or more.
- the thermal expansion coefficient of the cemented carbide is approximately 5-6 ⁇ 10 ⁇ Since the thermal expansion coefficient of carbon steel is approximately 11 to 12 ⁇ 10 ⁇ 6 / ° C., the thermal expansion coefficient of cemented carbide is smaller.
- the diameter of the movable through hole 7a and the fixed through hole 5a at room temperature is R1 mm, and the outer diameter of the press-fit portion 10c of the guide pin 10 and the outer diameter of the guide bush 9 at room temperature are tightened. Considering R1 + 0.01 mm.
- the guide pin 10 and the guide bush 9 are made of cemented carbide and the movable side mold plate 7 and the fixed side mold plate 5 are made of carbon steel. What is necessary is just to manufacture with the material whose coefficient of thermal expansion is smaller than the side mold plate 7 and the fixed side mold plate 5. Of course, it is preferable to use a guide pin 10 and a guide bush 9 having the smallest possible tolerance because the positioning accuracy can be further improved. Further, although the movable side mold plate 7 and the fixed side mold plate 5 are heated to the mold set temperature or higher by the heating means, the guide pin 10 and the guide bush 9 are also heated by the heating means and thermally expanded. It may be inserted into the movable side through hole 7a and the fixed side through hole 5a.
- the injection mold 1 has been described.
- the present invention is not limited thereto, and it is necessary to accurately move a press mold using a punch and a die and other movable side members with respect to the fixed side member.
- the mold manufacturing method of the present invention can be applied to all molds.
- the present embodiment is characterized in that two or more sets of guide members 20 including guide pins 10 and guide bushes 9 are used.
- the position where two or more sets of one set of guide members 20 are attached is not particularly limited, but as shown in FIG.5 (a), the injection space 11 is formed while leaving the guide pins 30 and the guide bushes 31 already provided on the mold base. Attach it at an angle, or remove the existing guide pin 30 and guide bush 31 as shown in Fig.

Abstract
La présente invention concerne un procédé de fabrication de moule capable de maintenir une précision de positionnement entre un élément côté mobile et un élément côté fixe pendant longtemps. Le procédé de fabrication de moule selon la présente invention comprend : une étape de formation d'un trou de pénétration côté mobile (7a) et d'un trou de pénétration côté fixe (5a) par usinage simultané avec un élément côté mobile (7) ou similaire et un élément côté fixe (5) ou similaire surimposés l'un sur l'autre pour fabriquer le trou de pénétration côté mobile et le trou de pénétration côté fixe ayant le même diamètre ; et une étape d'insertion d'une broche de guidage (10) et d'une brosse de guidage (9) dans le trou de pénétration côté mobile et le trou de pénétration côté fixe, respectivement, après le chauffage d'au moins l'élément côté mobile et l'élément côté fixe à une température supérieure à une température de réglage du moule pour fixer la broche de guidage et la brosse de guidage par ajustement par rétrécissement. Dans la mesure où la broche de guidage et la brosse de guidage sont ajustées par rétrécissement ensemble après être chauffées à la température supérieure à la température de réglage du moule et sensiblement thermiquement expansées, un espace n'est pas généré entre le trou de pénétration côté mobile et le trou de pénétration côté fixe, moyennant quoi la précision de positionnement entre l'élément côté mobile et l'élément côté fixe peut être maintenue pendant longtemps.
