Abstract
A molding machine (1) may include first and second dies (13, 23) arranged and constructed to be closed and opened, and first and second trimming members (17, 27) arranged and constructed to engage with each other after the first and second dies are closed. When the first and second dies (13, 23) are closed, a resin based sheet material (S′) is pressed so as to form a molded material (S). When the first and second trimming members (17, 27) engage with each other, the molded material (S) is circumferentially trimmed so as to produce a molded article (Sa) and a waste strip (Sb).
Claims12
A molding machine, comprising:
- first and second dies arranged and constructed to be closed and opened;
- and
- first and second trimming members arranged and constructed to engage with each other after the first and second dies are closed,
- wherein the first die is arranged and constructed to move relative to the first trimming member after the first and second dies are closed, wherein when the first and second dies are closed, a resin based sheet material is pressed so as to form a molded material, wherein when the first die is moved relative to the first trimming member together with the second die, the first and second trimming members engage with each other and circumferentially trim the molded material so as to produce a molded article and a waste strip, and wherein the first trimming member and the first die are arranged and constructed such that the produced molded article can be retained on the first die by means of the first trimming member when the first and second dies are opened.
1 more element
A molding machine, comprising:
- a first base member;
- a second base member arranged and constructed to move toward and away from the first base member;
- a first die moveably connected to the first base member;
- a second die connected to the second base member;
- a first trimming member attached to the first base member;
- and
- a second trimming member attached to the second die;
- wherein when the second base member is moved toward the first base member, the first and second dies close so that a sheet material is pressed so as to form a molded material, wherein the first die is arranged and constructed to move relative to the first trimming member after the first and second dies are closed, wherein when the second base member is further moved toward the first base member, the first die moves relative to the first trimming member together with the second die such that the first and second trimming members engage with each other, thereby circumferentially trimming the molded material so as to produce a molded article and a waste strip, and wherein the first trimming member is associated with the first die and is arranged and constructed such that the produced molded article can be retained on the first die by means of the first trimming member when the first and second dies are opened.

A molding machine, comprising:
- a first base member;
- a second base member arranged and constructed to move toward and away from the first base member;
- a first die moveably connected to the first base member;
- a second die connected to the second base member;
- a first trimming member attached to the first base member;
- a second trimming member attached to the second die;
- and
- actuable means for moving the first die relative to the first base member;
- wherein when the second base member is moved toward the first base member, the first and second dies close so that a sheet material is pressed so as to form a molded material,
- wherein when the second base member is further moved toward the first base member and the actuable means are deactivated, the first die moves relative to the first trimming member together with the second die such that the first and second trimming members engage with each other, thereby circumferentially trimming the molded material so as to produce a molded article and a waste strip;
- and
- wherein the first die retains its position relative to the first trimming member when the first and second dies are opened;
- and
- wherein the actuable means moves the first die relative to the first trimming member so as to release the waste strip after the first and second dies are opened.
