    • PURPOSE: An injection mold for a diaphragm for a washing machine is provided to reduce the stripes on the diaphragm by dispersing materials forming TPE(Thermoplastic Elastomer) by using a plurality of pin holes. CONSTITUTION: An injection mold(20) for a diaphragm for a washing machine comprises first and second cores(203, 204), first and second intermediate cores(205, 206), and first and second slide cores(207, 208). The gap between the first and the second cores is adjustable. The first intermediate core is installed between the first and the second cores and formed into fit to the inner surface of a body. The second intermediate core is installed in the outer surface of the first intermediate core and formed to be fit to the shape corresponding to the exterior of a body. The first and the second slide cores form first and second undercuts with the first and the second cores respectively. Cavities fit to the diaphragm are formed between the first and second cores, the first and the second intermediate cores, and the first and the second slide cores.
    • 目的:提供一种用于洗衣机隔膜的注射模具,通过使用多个针孔分散形成TPE(热塑性弹性体)的材料来减小隔膜上的条纹。 构成:用于洗衣机的隔膜的注射模具(20)包括第一和第二芯(203,204),第一和第二中间芯(205,206)以及第一和第二滑动芯(207,208)。 第一和第二芯之间的间隙是可调节的。 第一中间芯安装在第一和第二芯之间并且形成为适合于身体的内表面。 第二中间铁心安装在第一中间铁芯的外表面上,并形成为适合于与车体外部相对应的形状。 第一和第二滑动芯分别与第一和第二芯分别形成第一和第二底切。 在第一和第二芯,第一和第二中间芯以及第一和第二滑动芯之间形成适合于隔膜的腔。
