模内注塑成型模具装置及其树脂成型品的制造方法
Abstract:
模内注塑成型模具装置(1)的阴模(20)具有第一抽吸孔(31)、第二抽吸孔(32)和凹状的抽吸槽(33)。第一抽吸孔(31)在阴模(20)的空腔(21)的底面(22)开口。第二抽吸孔(32)在阴模(20)的夹持面(25)中比夹持器(40)靠内侧的部分开口，阳模(10)与所述阴模(20)的所述夹持面(25)之间夹着装饰薄膜(100)而抵接。抽吸槽(33)以将空腔(21)与第二抽吸孔(32)连通的方式形成在阴模(20)的表面。第一抽吸孔(31)、第二抽吸孔(32)和抽吸槽(33)在将划定空腔(21)的空腔面(22、23、24)与装饰薄膜(100)之间的空间部(SA)中的空气排出时作为排气通路而发挥作用。
Abstract(English):

A female mold (20) of an in-mold injection molding mold device (1) has a first suction hole (31), a second suction hole (32), and a concave suction groove (33). The first suction hole (31) opens in a bottom surface (22) of a cavity (21) of the female mold (20). The second suction hole (32) opens in a part, to the inside of a clamper (40), of a clamping surface (25) of the female mold (20) on which a male mold (10) abuts, with a decoration film (100) held therebetween. The suction groove (33) is formed on a front surface of the female mold (20) so as to make the cavity (21) and the second suction hole (32) communicate with each other. The first suction hole (31), the second suction hole (32), and the suction groove (33) function as exhaust paths when air in a space (SA) between cavity surfaces (22, 23, and 24) defining the cavity (21) and the decoration film (100) is being discharged.
