- Patent Document 1 discloses that a rectangular mold recess and a mold extend so as to spread adjacent to the cavity surface of a mold. Convex portions are formed continuously, and portions having a large molten metal flow resistance and small portions are alternately configured, and the direction of one side of the rectangular mold concave portion and the mold convex portion is set with respect to the molten metal injection direction. There is disclosed a die casting method in which the molten metal injected is uniformly filled in each part of the cavity by inclining.
- the concavo-convex portion is formed by embossing or electric discharge machining that forms the concavo-convex portion by corroding the cavity surface with a nitric acid-based corrosion liquid or the like.
- these machining methods have a problem that the range in which the cavity surface can be machined is limited, and a mold having a complicated cavity shape cannot obtain sufficient molten metal flow.

- the shape of the concavo-convex portion to be formed is square, galling or the like is likely to occur when the cast product is released from the mold, and the ease of release from the mold (releasability) is reduced. There was a problem.
- the concavo-convex part has directionality in one direction, the release agent for improving the releasability when applied to the cavity surface becomes difficult to stay uniformly on the cavity surface, so the releasability is reduced. There was a problem to do.

- the shape of the injection material can be indefinite, spherical, or other shapes, but if an indeterminate type of injection material is used, its grinding action will work, and the cavity surface 11 will be ground to obtain the dimensional accuracy of the mold 10. Therefore, it is preferable to use a spherical injection material mainly having a plastic deformation action for forming the dimples. Moreover, when a spherical injection material is used, the peening effect by provision of a residual stress can also be show
- injection material that satisfies the above-described characteristics include, for example, iron-based amorphous spherical particles described in JP-A-2002-4015 and JP-A-2005-76083, which were previously developed by the applicant of the present invention. It can be used suitably.

Abstract
Description
また、形成される凹凸部の形状が、角張っているため、鋳造品の金型からの離型時にかじりなどが生じやすく、金型からの離型のしやすさ(離型性)が低下するという問題があった。凹凸部が一方向に方向性を有するような場合には、キャビティ面に塗布し、離型性をよくするための離型剤が、キャビティ面に均一に留まりにくくなるため、離型性が低下するという問題があった。
実施例は加工方法(a)により実施したもので、金型材料として用いた試験片の加工前と各噴射加工工程後の表面(キャビティ面11)の表面性状の形態を図4〔1〕~〔3〕に示す。本実施例を以下に、前記の図を用いて詳細を説明する。なお、本発明は以下の実施形態に限定されるものではない。
本実施例では、ダイカスト金型により薄板材を鋳造し、従来のシボ加工によるキャビティ面との湯流れ性の比較を行った。鋳造条件のばらつきの影響を排除するため、キャビティ形状が左右対称の金型を用意し、左半分のキャビティ面に従来のシボ加工、右半分のキャビティ面に本発明の噴射加工を施して、湯流れ性を比較した。湯流れ性の評価は、鋳造品の左半分の部分の密度と、右半分の部分の密度とを比較することにより行った。湯流れ性が悪い場合には、充填不良や気泡の巻き込みなどが生じるため、密度が低下する。
本発明のキャビティ面の加工方法によれば、噴射加工工程Bにより、キャビティ面11の加工痕等をなくして方向性のない表面性状にするとともに、湯流れ性を向上させるための微小な第2のディンプル13を形成することができる。そして、噴射加工工程Aにより第2のディンプル13よりも大きく、半球面状に形成された第1のディンプル12を形成して、第2のディンプル13と第1のディンプル12とが混在するキャビティ面11を形成することができる。これにより、第2のディンプル13と第1のディンプル12とがキャビティ面11で方向性なく均一に分散し、溶湯がキャビティ面11と接触する面積を低減させることができるので、湯流れ性を向上させることができる。また、第1のディンプル12は、半球面状のディンプルに形成されるため、鋳造時にキャビティ面11に塗布する離型剤を留まりやすくすることができる。また、シボ加工などで形成されたディンプルと異なり、角のない半球面状に形成することにより、鋳造品の離型時にかじりなどが生じることがなく、鋳造品の離型を容易にし、鋳造品に傷をつけないようにすることができる。また、第2のディンプル13と第1のディンプル12とは、噴射加工により形成されるため、複雑なキャビティ形状を有する金型のキャビティ面にも形成することができる。
上述した実施形態では、主にダイカスト鋳造に用いる金型について説明したが、本発明はこれに限定されるものではなく、低圧鋳造、吸引差圧鋳造など各種鋳造法に用いられる金型に対して適用することができる。
また、本発明は本明細書の詳細な説明により更に完全に理解できるであろう。しかしながら、詳細な説明および特定の実施例は、本発明の望ましい実施の形態であり、説明の目的のためにのみ記載されているものである。この詳細な説明から、種々の変更、改変が、当業者にとって明らかだからである。
出願人は、記載された実施の形態のいずれをも公衆に献上する意図はなく、開示された改変、代替案のうち、特許請求の範囲内に文言上含まれないかもしれないものも、均等論下での発明の一部とする。
本明細書あるいは請求の範囲の記載において、名詞及び同様な指示語の使用は、特に指示されない限り、または文脈によって明瞭に否定されない限り、単数および複数の両方を含むものと解釈すべきである。本明細書中で提供されたいずれの例示または例示的な用語(例えば、「等」)の使用も、単に本発明を説明し易くするという意図であるに過ぎず、特に請求の範囲に記載しない限り本発明の範囲に制限を加えるものではない。
