Abstract
A tool for multi-component injection molding of plastic toothbrush bodies 4 for toothbrushes has two tool halves 1, 1′ which can be opened and closed. In one tool half 1 a linearly movable transfer device 6 is arranged. The hollow mold spaces 2 for injection molding the first component are formed exclusively by the two tool halves 1, 1′. For transferring the injection-molded blanks (3) in the second station, the transfer device 6 moves into the area of the injection-molded blanks 3, picks them up by vacuum suction cups 11, and transfers the injection-molded blanks 3 by linear movement into the second station.
Claims13
A tool for multi-component injection molding of plastic toothbrush bodies (4) for toothbrushes, the tool comprising:
- two tool halves (1, 1′) forming hollow mold spaces (2) and configured to move apart into an open position and to move together into a closed position;
- wherein the hollow mold spaces (2) comprise first cavities for injection molding first components of the toothbrush body (4) and second cavities for forming second components of the toothbrush body (4), wherein the first cavities are delimited exclusively by the two tool halves (1, 1′);
- a transfer device (6) integrated into a first one of the two tool halves (1) and immersible into the first tool half (1);
- wherein the transfer device (6) is configured to transfer injection-molded blanks (3) formed in the first cavities into the second cavities for injection molding the second components;
- wherein the transfer device (6) in the closed position of the two tool halves (1, 1′) is located outside of the first cavities;
- wherein the transfer device (6) is configured to move, after injection molding of the first components, into the first cavities of the injection-molded blanks (3), to pick up the injection-molded blanks (3), and subsequently transport the injection-molded blanks into the second cavities for injection-molding the second components.
