Description
本発明は、所定形状を有するキャビティを形成するために互いに密着する状態と互いに密着しない状態とに選択的に切り換わるめす型およびおす型を有する成形型ユニットに関するものである。 The present invention relates to a mold unit having a female and male mold switched selectively into a state not in close contact with each other in a state in close contact with each other to form a cavity having a predetermined shape.
そこで、本発明は、所定形状を有するキャビティを形成するために互いに密着する状態と互いに密着しない状態とに選択的に切り換わるめす型およびおす型を有する成形型ユニットを提供することを課題としてなされたものである。 In view of the above, an object of the present invention is to provide a mold unit having a female mold and a male mold that are selectively switched between a state in which they are in close contact with each other and a state in which they are not in close contact with each other in order to form a cavity having a predetermined shape. It is a thing.
その課題を解決するために、本発明の一側面によれば、所定形状を有するキャビティを形成するために互いに密着する状態と互いに密着しない状態とに選択的に切り換わるめす型およびおす型を有する成形型ユニットが提供される。
本発明の別の側面によれば、所定形状を有するキャビティを形成するために互いに密着する状態と互いに密着しない状態とに選択的に切り換わるめす型およびおす型を有する成形型ユニットを用い、液状の混合材料から、合成樹脂製の製品を成形する方法であって、前記めす型内の空間を前記材料で充填する充填工程と、前記めす型に前記おす型を、それらめす型およびおす型の回転中にそれらめす型およびおす型のうちの少なくとも一方に発生する慣性力と遠心力とのうちの少なくとも一方によってそれらめす型とおす型とが互いに相対的に接近して最終的に前記めす型に前記おす型が密着することが可能であるように、組み付ける組付け工程と、前記めす型を、そのめす型に前記おす型が組み付けられた状態で、かつ、前記めす型内の空間が前記材料で充填されている状態で、攪拌機内に配置し、その攪拌機により、前記めす型および前記おす型を、真空圧下において、公転軸まわりに公転させつつ、その公転軸に対して偏心した自転軸まわりに自転させ、それにより、前記めす型に前記おす型が密着することによってそれらめす型とおす型との間に形成された前記キャビティ内において前記材料を攪拌しつつ脱泡する攪拌脱泡工程と、前記成形型ユニット内の前記材料を硬化させる硬化工程とを含み、前記攪拌脱泡工程は、前記公転および前記自転のうちの少なくとも一方の速度を時間的に変化させ、それにより、前記めす型に前記おす型が密着しない型開き状態と、前記慣性力と遠心力とのうちの少なくとも一方によって前記めす型に前記おす型が密着する型締まり状態とをそれらの順に実現する成形方法が提供される。
In order to solve the problem, according to one aspect of the present invention, in order to form a cavity having a predetermined shape, a female mold and a male mold that selectively switch between a state in which they are in close contact with each other and a state in which they are not in close contact with each other are provided. A mold unit is provided.
According to another aspect of the present invention, a mold unit having a female mold and a male mold that are selectively switched between a state in which they are in close contact with each other and a state in which they are not in close contact with each other in order to form a cavity having a predetermined shape is used. A method of molding a product made of synthetic resin from the mixed material, a filling step of filling a space in the female mold with the material, the male mold into the female mold, the female mold and the male mold At least one of the inertial force and centrifugal force generated in at least one of the female mold and the male mold during rotation causes the female mold and the male mold to approach each other and finally become the female mold. An assembling step for assembling the female mold so that the male mold can be in close contact with the female mold in a state where the male mold is assembled to the female mold and the female mold is empty. Is placed in a stirrer in a state filled with the material, and the female mold and the male mold are revolved around the revolving axis under a vacuum pressure by the agitator, and are eccentric with respect to the revolving axis. Stirring and defoaming that rotates around the rotation axis, thereby degassing the material in the cavity formed between the female mold and the male mold when the male mold is in close contact with the female mold. And a curing step for curing the material in the mold unit, wherein the stirring and defoaming step changes the speed of at least one of the revolution and the rotation with time, thereby A mold opening state in which the male mold is not in close contact with the female mold, and a mold clamping state in which the male mold is in close contact with the female mold by at least one of the inertial force and the centrifugal force. Molding process to realize their order is provided.
Claims (4)
前記おす型と一体的に運動する第１部材と、 A first member that moves integrally with the male mold;
前記めす型と一体的に運動する第２部材と A second member that moves integrally with the female mold;
を含み、 Including
それら第１部材および第２部材は、相対移動可能に互いに係合するガイドピンとガイド長穴またはガイド溝との組合せにより、互いに相対的に回転可能かつ軸方向移動可能であるとともに、前記第１部材および前記第２部材の間の軸方向における相対接近限度位置が、前記おす型が前記めす型に密着することを阻止する位置と許可する位置とに、前記第１部材および前記第２部材の間の回転方向相対位置に応じて変化する請求項２に記載の成形型ユニット。 The first member and the second member are rotatable relative to each other and movable in the axial direction by a combination of a guide pin and a guide slot or guide groove that engage with each other so as to be relatively movable. And the relative approach limit position in the axial direction between the second member and the position where the male mold is prevented from coming into close contact with the female mold, and the position where the male mold is allowed to be allowed. The mold unit according to claim 2, which changes according to the relative position in the rotation direction.
