Definitions

  • the invention relates to a plastic molding tool with a core and a die, a cavity being formed between them which corresponds to the shape of a plastic part to be created.
  • inserts functional elements
  • B a threaded press-fit bush
  • the manual clamping of the inserts has the disadvantage that it is expensive and is often only extremely unergonomic (eg inserts deep in the die). There is also a risk of forgetting, i. H. this is an unsafe process.
  • the automatic insertion by a robot has the disadvantage of unsafe insertion, ie the insert often comes loose when the robot is moved back. This then leads to poor sealing of the insert against the liquid plastic. The insert often slips completely. This always leads to increased rejects. It is also very difficult to check whether the insert is correctly positioned. The inserts also form obstacles in the plastic flow. This results in flow seams and a weakening of the component. Therefore, according to the state of the art, only the subsequent assembly on the finished molded plastic part remains, which is, however, an additional work step and thereby makes the molded part more expensive.
  • the invention is based on the object of improving a plastic molding tool in such a way that inexpensive and process-reliable insertion of inserts into the tool is possible.
  • this object is achieved in that a feed device for inserting inserts into the cavity is arranged in the die.
  • the feed device consists of a slide which can be displaced in a slide channel, the front end of which, in the extended position of the slide, is flush with the cavity wall and the slide exposes a feed channel for feeding the inserts into the slide channel in the retracted state.
  • the slide is displaceable in the slide channel via a hydraulic cylinder.
  • a holding device for the inserts which preferably consists of a vacuum connection, is expediently arranged at the front end of the slide.
  • the vacuum connection preferably consists of a central bore arranged in the slide, which is provided with a pump connection via channels in the slide and in the die.
  • the channel in the slide is advantageously connected to the channel in the die via a groove extending in the longitudinal direction of the slide.
  • the slide channel is preferably connected to the atmosphere via a cleaning hole in the die.
  • the actual positioning in the still liquid plastic can be delayed, so that the material flow is disturbed much less and fewer weld lines are formed *.
  • the essence of the invention lies in the fact that the inserts are not introduced from below through the opening of the die, but rather are introduced transversely through the wall of the die or from below across the punch into the contour of the mold.
  • the single figure shows schematically a section of a plastic molding tool.
  • a cavity 2 is arranged between the die 1 and a core (not shown), which corresponds to the shape of a plastic part to be created.
  • the liquid plastic is filled into this cavity.
  • a slide channel 4 is arranged in the die 1, in which a slide 5 is slidably arranged via a hydraulic cylinder 9.
  • the front end 6 of the slide 5 is flush with the cavity wall 7 in the extended position of the slide 5.
  • this exposes a feed channel 8 for feeding the inserts 3 into the slide channel 4.
  • the inserts 3 thus enter the slide channel 5 via the feed channel 8 and from there they are pushed into the cavity 2 by the slide 5.
  • a central bore 10 is provided in the slide 5, which extends from the front end 6 of the slide 5 via a groove 13 and channels 11 to a pump connection 12.
  • a vacuum pump is flanged to the pump connection 12, so that the inserts 3 are fixed on the slide 5 by a negative pressure.
  • a cleaning bore 14 is arranged in the die 1, which connects the slide channel 4 to the atmosphere.

Abstract

L'invention concerne un moule plastique comprenant un noyau et une matrice (1) entre lesquels une cavité (2) est formée. La forme de cette cavité correspond à une pièce en plastique à créer. L'invention vise à obtenir une introduction économique et sûre d'inserts dans le moule. A cet effet, on place un dispositif d'alimentation dans la matrice (1) pour l'introduction d'inserts (3) dans la cavité (2).
