SU1736722A1 - Casting form with mechanical separation of spot runners - Google Patents

Abstract

Use: relates to the processing of polymeric materials and can be used in injection molds to form plastic products using a point inlet sprue. SUMMARY OF THE INVENTION: The casting mold comprises a punch 1, a die 2 with four sprue bushings 3, an intermediate plate 4, screwed with a die 2 and in which a slot for a floating lock-divider 6 is made, a runner plate 7 screwed with a fixing fixed plate 8 in which a slot 9 is made under the floating rod 10 of square section with a fork at the end for acting on a gate having hanger-pullers 11 for interacting with the die 2; on the other end of the rod 10 there are fixed stops made in the form of nuts 12 for limiting moving the rod 10, the central sprue bushing 13, the removal plate 14 for ejecting the finished product 15 formed in the die 2 and the punch 1 of the sprue 16. 2 Il.

Claims (1)

Claim An injection mold with a mechanical separation of point sprues containing a sprue plate, a matrix, an intermediate plate with sprue ejector overlapping the base of the sprue channels, characterized in that, in order to increase the reliability of the form, the sprue ejector is made in the form of a floating rod square cross-section with a fork at the end for acting on the gate, which has shoulders-pullers for interacting with the matrix, and stops at the second end of the rod are installed to limit the movement of the rod.
