    • The invention relates to a mould (1) for back-injection of a plastic film (4) with molten plastic, and a corresponding process for producing a plastic moulded article in the cavity (11) formed by a first and second mould part (2, 3). The first mould part (2) has a decorating surface zone (21), a clamping surface zone (22) arranged outside of the latter, and a recessed zone (23) arranged at least outside of the decorating surface zone (21). The second mould part (3) has an inlet (31) for the molten plastic and a projecting zone (33). The projecting zone (33) is arranged so that, when the tool is closed, it engages with the recessed zone (23), in order to hold the plastic film (4) arranged between the first mould part (2) and the second mould part (3), lying on the clamping surface zone (22) of the first mould part, in the recessed zone (23) under tension.
    • 本发明涉及一种用熔融塑料反向注塑塑料薄膜(4)的模具(1),以及在由第一和第二模具部件(2)形成的空腔(11)中制造塑料模塑制品的相应工艺 ,3)。 第一模具部件(2)具有装饰表面区域(21),布置在其后面的夹紧表面区域(22)和至少布置在装饰表面区域(21)的外部的凹陷区域(23)。 第二模具部分(3)具有用于熔融塑料的入口(31)和突出区域(33)。 突出区域(33)被布置成使得当工具关闭时,其与凹陷区域(23)接合,以便将设置在第一模具部件(2)和第二模具(2)之间的塑料膜(4) 位于第一模具部件的夹紧表面区域(22)上的部分(3)在张力下位于凹进区域(23)中。

    • An apparatus for manufacturing product with decorative patterns includes a fixed and a movable mold base, and a decorative film. A fixed mold insert is fitted in the fixed mold base and is provided with a sprue and at least one molding cavity.The movable mold base is movable toward or away from the fixed mold base and includes an ejector pin unit and a movable mold insert, which is provided with at least one material receiving cavity. The decorative film is placed in between the fixed and the movable mold insert to cover the molding cavity and material receiving cavity, and is provided with a material passing opening corresponding to the sprue. A method for manufacturing product with decorative patterns is also disclosed to ensure increased yield rate of injection molded products with varied and precise surface patterns through effective cost control in the manufacturing process.
    • 用于制造具有装饰图案的产品的装置包括固定和可动模底座以及装饰薄膜。 固定模具插入件安装在固定模具基座中并且设置有浇口和至少一个模制腔。 可移动模具底座可以朝向或远离固定模具基座移动,并且包括顶针单元和可移动模具插入件,其设置有至少一个材料容纳腔。 将装饰膜放置在固定和可移动的模具插入件之间以覆盖模制腔和材料容纳腔,并且设置有对应于浇道的材料通过开口。 还公开了一种用于制造具有装饰图案的产品的方法,以通过在制造过程中的有效成本控制来确保具有各种和精确表面图案的注塑产品的提高的产率。
