より詳細には、例えば、上下位置に樹脂成形用の上型と下型とを対向配置すると共に、樹脂成形時に該上下両型の外方周囲を外気遮断部材にてシールし、且つ、該シール範囲を減圧した状態で樹脂成形を行う、所謂、減圧成形(真空成形)手段を採用した樹脂成形装置において、その上型と下型とを簡易に交換することができる型交換方法と型交換機構、及び、この型交換機構を備えた樹脂成形装置の改良に関するものである。
The present invention relates to a method for replacing a resin molding die mounted on a resin molding apparatus such as a resin sealing molding apparatus for an electronic component used for resin sealing molding of a semiconductor lead frame or a semiconductor chip on a semiconductor substrate. The present invention relates to an exchange mechanism for carrying out the method and a resin molding apparatus provided with the mold exchange mechanism.
More specifically, for example, an upper mold and a lower mold for resin molding are arranged opposite to each other at the upper and lower positions, and the outer periphery of both upper and lower molds is sealed with an outside air blocking member during resin molding, and the seal Mold changing method and mold exchanging mechanism for easily exchanging the upper mold and the lower mold in a resin molding apparatus adopting so-called reduced pressure molding (vacuum molding) means for performing resin molding in a state where the range is decompressed Further, the present invention relates to an improvement of a resin molding apparatus provided with this mold exchanging mechanism.

電子部品の樹脂封止成形装置に減圧成形手段を採用することは知られており、また、その減圧成形手段の一機構として、上下両型の外方周囲を外気遮断部材にてシールするように構成することが知られている(例えば、特許文献1参照)。   It is known to employ a reduced pressure molding means in a resin sealing molding apparatus for electronic parts, and as one mechanism of the reduced pressure molding means, the outer periphery of both upper and lower molds is sealed with an outside air blocking member. It is known to configure (see, for example, Patent Document 1).

特許文献1には次のような構成が開示されている。
即ち、上型の外方周囲をシールする外気遮断部材については、その一端側を上型取付板に枢着し、且つ、その他端側を上下方向へ回動可能となるように構成することにより、上型の交換時には該上型用外気遮断部材を上型交換作業に障害(邪魔)にならない位置にまで回動退避させることができる。
また、下型の外方周囲をシールする下型用外気遮断部材については、該外気遮断部材を固着ボルトを介して従って、型取付板に固着するように構成している。
そして、下型の交換手段としては、まず、固着ボルトを取り外して上下の両型面間に第一の型交換治具を介在させる。
次に、この状態で該下型用外気遮断部材と固定レールとの間に第二の型交換治具を嵌装させて該下型用外気遮断部材を固定する。
次に、固着ボルトによる下型用外気遮断部材との固着状態が解かれた下型取付板を下方の所定位置にまで下動させると共に、これと同時に下型を下動させる。
従って、このとき、下型用外気遮断部材を下型の外方周囲から取り外す(退避させる)ことができるので、この状態において下型の取り付けや取り外しと云った下型の交換作業を行うことが可能となる。
Patent Document 1 discloses the following configuration.
That is, the outside air blocking member that seals the outer periphery of the upper die is configured such that one end side thereof is pivotally attached to the upper die mounting plate and the other end side thereof is rotatable in the vertical direction. When the upper mold is replaced, the upper mold outside air blocking member can be rotated and retracted to a position where it does not interfere (obstruct) the upper mold replacement operation.
Further, the lower mold outside air blocking member that seals the outer periphery of the lower mold is configured so that the outside air blocking member is fixed to the mold mounting plate via the fixing bolt.
As the lower mold exchanging means, first, the fixing bolt is removed, and the first mold exchanging jig is interposed between the upper and lower mold surfaces.
Next, in this state, a second mold exchanging jig is fitted between the lower mold outside air blocking member and the fixed rail to fix the lower mold outside air blocking member.
Next, while lowering the lower mold attachment plate, which has been unfixed with the lower mold outside air blocking member by the fixing bolt, to a predetermined position below, the lower mold is moved downward simultaneously.
Therefore, at this time, the lower mold outside air blocking member can be removed (retracted) from the outer periphery of the lower mold, and therefore, in this state, the lower mold can be exchanged by attaching and removing the lower mold. It becomes possible.

しかしながら、このような構成による下型の交換手段においては、固着ボルトの取り外し作業と、第一の型交換治具を上下の両型面間へ介在させる作業と、下型用外気遮断部材と固定レールとの間に第二の型交換治具を嵌装させて該下型用外気遮断部材を固定する作業と、下型を下動する作業とを終えた後に下型交換作業とを行う必要がある。
従って、このような型交換方法では、全体的な作業が複雑且つ面倒であるのみならず、型交換作業に作業上の熟練性と作業時間が長くなる等の問題がある。
However, in the lower mold exchanging means having such a configuration, the fixing bolt is removed, the first mold exchanging jig is interposed between the upper and lower mold surfaces, and the lower mold outside air blocking member is fixed. It is necessary to perform the lower mold replacement work after the work of fixing the lower mold outside air blocking member by fitting the second mold replacement jig between the rail and the lower mold is completed. There is.
Therefore, in such a mold changing method, not only the overall work is complicated and troublesome, but also there are problems such as the work skill and work time of the mold changing work become long.

また、近年、コストダウンを目的として、半導体基板等や成形用型を大形化することにより高能率生産を図る傾向にある。
更に、減圧成形手段を採用する樹脂成形装置においては、型の大形化に伴ってその外気遮断部材も大形化されることになる。
このような型やその外気遮断部材の大形化は、例えば、樹脂成形品の品種切替時や型のメンテナンス時等において樹脂成形装置に対する型交換作業を行う際に、該型とその外気遮断部材の取り扱いが困難となり、従って、型交換作業の操作性や作業効率が悪くなると云った問題がある。
In recent years, there is a tendency to achieve high-efficiency production by increasing the size of a semiconductor substrate or the like and a mold for the purpose of cost reduction.
Furthermore, in the resin molding apparatus that employs the reduced pressure molding means, the outside air blocking member is also increased in size as the mold is increased in size.
Such a mold and its outside air blocking member are increased in size when, for example, the mold and its outside air blocking member are replaced when the mold is exchanged for the resin molding apparatus at the time of changing the type of the resin molded product or maintaining the mold. Therefore, there is a problem that the operability and work efficiency of the mold exchanging work are deteriorated.
