DE1950826C - Injection mold or vulcanization mold for the production of footwear with a closing flap attachment on the upper - Google Patents

Description

30th

The invention relates to an injection molding or VuI-Kanisierform with a last, a two-part side mold and a headstamp for making of footwear, especially ski boots, the shaft of which has an elongated approach on the closing flap having, wherein a relative to this movable insert is arranged on the strip, which in The closed position of the mold is held in the correct position at a distance from the ledge and the inside of the Closing flap approach limited, while the outside of the closing flap approach by the Side shape is limited. Such a shape is known, for example, from the French patent specification 1459 556.

The invention is based on the object of further developing and improving the known form, such that in a particularly simple manner the production of an elongated closing flap approach on which one free edge of the shaft is made possible, which is the free edge of the other shaft closing flap overlaps. The closing flap approach can be an elongated closed piece or divided, in the manner of parallel belts.

The invention consists in that the insert piece is in the working position for producing one for closing of the footwear serving, elongated closing flap approach on the one free edge of the upper part of the shaft, which overlaps the other free edge of the shaft, only partially at a distance is held by the last, while it is moreover, lying against the groin neck, on the head part of the last is pivotally attached.

Instead of the preferably two-part side shape, different designs can of course also be used Side shapes are used.

In the drawing, an embodiment is shown, namely shows

In the working position, the injection molding or vulcanizing mold 10 receives a strip 11 which, in a known manner, can be divided, for example, along the dividing line 12. The vulcanizing mold 10 consists of a divided side mold with the mold halves 10a, 10b and a head stamp 10c. The mold 10 with lasts 11 is preferably intended for the production of ski boots, consisting of an upper 13 with sole 14 and a closing flap attachment 15. The closing flap attachment 15 is part of the upper 13 and is used to close the footwear at the foot of the shoe wearer by means of known locking means.

For better visibility, the closing flap attachment 15 is cross-hatched in FIG. 2, while the shaft 13 is simply hatched. On the last 11 there is an insert which is movable relative to the latter 16 arranged, which in the closed position of the mold 10 is held in the correct position at a distance from the strips 11 is, and the inside of the closing flap extension 15 is limited, while the outside of the The flap attachment 15 is limited by the side shape 10 ft.

In order to produce an elongated shaft piece serving as a closing flap attachment 15 on the one free edge 13a of the shaft 13, which overlaps the other free edge 13 & the same, it is provided according to the invention that the insert 16 in the working position is only partially, namely in the area of the a free edge 13 b and the shaft parts adjacent to this is held at a distance from the strips 11, while it rests directly on the strips 11 and with this one in the working position

represents connected part. The releasable contact surfaces of the insert 16 sai strips 11 are in FIG. 2 along line 17 and in FIG. 3 along line 18.

The insert 16 is on the upper part 11 α of the strip 11 on a shaft 19 by means of pivoting a fork 20, which has a handle 21, stored. The insert 16 can, for example, with a screw connection 22 to be screwed to an extension arm 20a dir fork 20.

As can be seen from Fig. 2, represents the insert
