摘要:
The mold comprises a matrix (30) and a punch (20) adapted to penetrate into the cavity of the matrix to determine the molding chamber of the mold, the object being formed through the pressure insertion of the punch (20) within the cavity of the matrix (30) where a metered body (8) of polymeric material has been previously placed whose mass is metered according to a reference value. According to the invention, the matrix (30) comprises at least one deformable wall (31) whose inner surface defines at least part of the surface of the matrix (30), said deformable wall (31) having, at least in part, a relatively thin thickness which permits it to be elastically deformed under the pressure of the polymeric material in the final molding step of the object, thereby absorbing the error of the mass of the metered body (8) with respect to the reference value.
摘要(中):
模具包括矩阵(30)和冲头(20),冲头(20)适于穿透基体的空腔以确定模具的模腔,该目标是通过将冲头(20)压入 已经预先安置了聚合物材料的计量体(8)的矩阵(30),其质量根据参考值计量。 根据本发明,基体(30)包括至少一个可变形壁(31),其内表面限定了基体(30)的表面的至少一部分,所述可变形壁(31)至少部分地具有 相对较薄的厚度,其允许其在物体的最终模制步骤中在聚合材料的压力下弹性变形,从而相对于参考值吸收计量体(8)的质量误差。
