Device for locking and unlocking skin forms

The invention relates to a device in order to, in particular continuous production of beard foam parts - ζ · Β · on Polystyrene base - to lock and unlock the forms «

A device has hitherto become known - expandable by means of steam Expand styrofoam grains so that they are firm or light Shaped bodies result, as they are in particular for insulation purposes and packaging purposes are needed

The previous devices for making such parts existed in filling stationary molds in order to then carry out the expansion by means of steam. Further development went to pressing set up with one or two tables. At these facilities or Machines, all work processes should be carried out in one station

Just the fact that it is especially with the packaging parts When it comes to very large numbers of items, the previous devices appear to be so inadequate that the applicant feels compelled to because of the many years of experience available to him To look for ways, and he came across continuous production, which he has further developed in various ways »

2 /.

As part of this development has shown to be particularly important a mechanized and, if possible, automated locking and unlocking of the foam molds, i.e. locking before ejection and an unlocking after ejection of the finished part. After various considerations and experiments, he has a device found, in which the locking and unlocking is carried out by a linearly moved bayonet lock. He makes this device an object his registration. The description follows below:

The locking of a removable upper mold is taken as an example with a fixed lower mold.

The device consists of the fixed lower _{mold (i) 5 of} the loose upper mold (2), the tabs (3), the guides (4) and elongated holes (5), locking tabs (6) and screws (7)

The guides (4) have the shape of a U-Sisens and are with the lower shape (1) rigidly connected. The elongated holes (5) and the cutouts (8) are incorporated in its upper web.

The locking tabs (6) also have the cutouts (8) and are fastened by means of screws (7) from the inside to the upper web of the guides (4) so that the screws are in the elongated holes (5) let move. The tabs (3) sit firmly on the upper and lower mold.

Using the attached drawing shows

Fig * II a non-locked upper mold, Fig. III a locked upper mold,

FIG. I shows a section C '/, D according to FIG. II.

Pig II Soil the upper mold is placed on the lower mold, are the cutouts (8) of the guides (4) and the locking tabs (6) one above the other, so that the upper mold (2) with the tabs (3) can be placed in the cutouts (8) from above. This position is achieved in that the The locking tab (6) is pushed in direction "A" as far as the - ^ anglöcher (5) allow »

Fig. III If the locking tabs are now pushed in direction ¹¹ B ", the hatched areas (9) of the locking tabs emerge from the cutouts (8) of the guides (4) and slide over the tabs (3) of the upper mold ( 2), whereby the upper mold is clamped to the lower mold »

If the shapes are to be separated again, the return * slide the locking tab (6) in direction "A" so that the cutouts (8) of the guide (4) and the locks tab (6) are again on top of each other so that the top mold can be removed upwards.

The device can be varied in many ways within the meaning of the invention will"
