Abstract
A blow mold machine, comprising two lockable mold halves. A locking element is fixed onto one mold half and a shaft with at least one recess is mounted in the other mold half. The shaft can be pivoted between a locking position, in which it lies against the locking element and a release position, in which the locking element can be displaced past the recess. A locking mechanism with a particularly simple construction can thus be achieved.
Claims12
A blow mold (1) with mold parts (3,4) for a stretch blow molding machine or the like, comprising at least one locking element (9, 28) attached to a first mold part (3), and at least one counter-element (10-a, b, c) attached to a second mold part (4), the counter-element (10-a, b, c) being a shaft (10-a, b, c) positioned in parallel to a connecting axis (2), around which the mold parts (3, 4) can be swiveled, which shaft is locked by means of rotation around a longitudinal axis (16-a, b, c) proceeding through the shaft, the shaft being rotatable between a locking position, in which the blow mold (1) is locked, and an unlocking position, in which the blow mold (1) can be opened, and the shaft (10-a, b, c) having such an external contour that the shaft (10-a, b, c) is, in the locking position, at least partially applied against the locking element (9, 28) and, in the unlocking position, releases the locking element (9, 21).
A blow molding machine comprising:
- a blow mold having at least one locking element attached to a first mold part, and at least one counter-element attached to a second mold part,
- the counter-element being a shaft positioned in parallel to a connecting axis, around which the mold parts can be swiveled which shaft is locked by means of rotation around a longitudinal axis proceeding through the shaft,
- the shaft being rotatable between a locking position, in which the blow mold is locked, and an unlocking position, in which the blow mold can be opened, and the shaft having such an external contour that the shaft is, in the locking position, at least partially applied against the locking element and, in the unlocking position, releases the locking element;
- and
- wherein the blow molding machine is adapted to stretch blow pre-molded blanks.
A blow mold (1) with mold parts (3, 4) for a stretch blow molding machine or the like, comprising at least one locking element (9, 28) attached to a first mold part (3), and at least one counter-element (10-a, b, c) attached to a second mold part (4), the counter-element (10-a, b, c) being a shaft (10-a, b, c), which is locked by means of rotation around a longitudinal axis (16-a, b, c) proceeding through the shaft, the shaft being rotatable between a locking position, in which the blow mold (1) is locked, and an unlocking position, in which the blow mold (1) can be opened, and the shaft (10-a, b, c) having such an external contour that the shaft (10-a, b, c) is, in the locking position, at least partially applied against the locking element (9,28) and, in the unlocking position, releases the locking element (9, 21);
- wherein two shafts (10-a, b) are attached on the second mold part (4), each of which shafts can each be rotated around a respective longitudinal axis (16-a, b) proceeding through it, between the locking position and the unlocking position;
- and
- wherein both of the shafts (10-a, b) are attached at a distance from one another in such a manner that, in the unlocking position, the locking element (9) is at least partially guided between both of the shafts (10-a, b) and, in the locking position, the contours of the two shafts (10-a, b) are at least partially applied to the locking element (9) in such a manner that the blow mold is solidly locked.
