Definitions
- the invention relates to a device for removing an injection-molded substrate from an injection molding tool according to the preambles of the independent claims 1 and 8.
- the invention further relates to an injection molding machine equipped with such a removal device according to the preamble of claim 16.
- optical data carriers such as CD, CD-R, DVD, DVD-R, single CD, OBC, or the like.
- the grippers with rubber suction cups used up to now are not able to remove and remove the substrate from the injection mold within a very short time. This is because the achievable swivel speeds depend on the holding force of the rubber suction cups. The inertial forces that occur during a rapid swiveling movement can become so great that the substrates completely slide off the rubber suction cups and drop or at least slip, so that the transfer to subsequent processing stations can no longer be carried out with the required positioning accuracy. As a result, the cycle time relevant for economical production can no longer be increased in the production of the optical data carriers.
- connection area between the substrate and the sprue part can be chosen so small that the cross section is just sufficient for the plastic melt to pass through.
- the sprue part protrudes slightly beyond the substrate in the connection area in the axial direction.
- the axial offset and the diameter of the part of the sprue projecting beyond the substrate so that when the sprue is separated from the substrate, a separating edge inclined at an angle of 45 ° to the plane of the opening of the substrate is produced and the injection molded part is 70% and the part to be separated is 30% of the axial length of the opening.
- the sprue part is held by an undercut in an axially movable sleeve in the tool, within which an ejector can be moved axially. By pulling back the sleeve, the sprue part is separated from the substrate along the narrow separating edge.
- the sleeve is moved further back until the sprue part is in the area of an opening in the injection mold.
- the sprue part is ejected from the sleeve and can fall out of the injection mold via the opening.
- a gripper is pivoted into the open injection mold, which is equipped with rubber suction cups, which are placed outside the information area of the optical data carrier, in particular within the so-called clamping area, in a manner known per se.
- the substrate can also be pushed into a drainage channel after removal from the mold become.
- the invention is therefore based on the object of initially specifying a device for removing an injection-molded substrate from an injection molding tool, in particular for substrates from optical data carriers, with which a rapid swiveling movement can be carried out without running the risk that the substrate will slip or even slip during the swiveling movement drops.
- the invention is furthermore based on the object of specifying an injection molding machine, in particular for producing a substrate for optical data carriers, with which short cycle times can be achieved on the one hand and with which it is possible at the same time to completely avoid dust formation within the injection molding tool.
- the first task is solved by a removal device with the features of the independent claims 1 and 8.
- the second task is accomplished by an injection molding machine with the features of the independent claim 16.
- the main advantage of the removal devices specified in the independent claims 1 and 8 is that the substrate sits positively on a pin (after removal of the sprue in the tool) or in a recess or opening in a substrate holding part (without removal of the sprue in the tool) and the pivoting speed of the lever is practically arbitrary can be increased without running the risk of the substrate slipping or even being lost during the pivoting movement.
- balls held under spring tension can be provided in the pin or the substrate is held by means of a vacuum on a shoulder on the pin (subclaims 5 and 6).
- a particularly short cycle time can be achieved if the lever only has to perform a pure pivoting movement, i.e. if the pin does not have to plunge into the opening of the substrate by means of an axial movement of the lever parallel to the pivoting axis in order to remove it from the mold half, but if , as indicated in subclaim 7, a sleeve which can be moved in the tool closing direction is provided in the tool half carrying the substrate and by means of which the substrate can be pushed onto the pin.
- the design according to claims 8 to 15 has the additional advantage that the sprue part can be separated outside the injection mold, so that in principle no dust formation can occur within the injection mold.
- the lever is equipped at one end with a substrate holding part which is suitable for receiving the sprue part. Either a recess (depression) is provided in the substrate holding part, into which the sprue part fits, at least with its area adjoining the substrate.
- the substrate holding part has an opening suitable for receiving the sprue part, so that the sprue part can protrude beyond the substrate holding part on the side facing away from the substrate; in this case too, the opening should be designed so that at least the region of the sprue part adjoining the substrate fits into the opening.
- the sprue part in such a way that it has a part protruding from the substrate and that the recess or the opening of the substrate holding part is adapted to the diameter of the protruding part of the sprue part. So that the sprue part does not jam in the substrate holding part, the diameter of the recess or the opening in the substrate holding part should be less than 0.05 mm, preferably 0.01 mm to 0.03 mm, larger than the diameter of the protruding part of the sprue part ).
- vacuum channels are provided in the support surface which generally do not exceed the clamping range (subclaim 14). Since there are no rubber suction cups on the substrate, no marks are left on the substrate, not even in the clamping area. This is advantageous in that squeegee marks lead to problems in the subsequent metallization of the
- a particularly short cycle time can also be achieved here if the lever only has to perform a pure swiveling movement, if the substrate holding part does not have to be moved towards the substrate parallel to the swiveling axis by an axial movement of the lever in order to demould it from the tool half, but if, as stated in subclaim 15, a sleeve which can be moved in the tool closing direction is provided in the tool half carrying the substrate and with which the substrate together with the sprue part can be pressed into the recess or the opening of the substrate holding part.
- the injection molding machine specified in patent claims 16 to 20, in particular for producing a substrate for optical data carriers, combines the advantages of fast removal handling in the embodiment of claims 8 to 15 with a sprue removal coordinated with this removal handling. In this way, both the cycle time is reduced and the problem of dust formation in the injection mold that arises when the sprue part is removed is completely eliminated due to the system. A clean separation process is possible due to the precise fit of the substrate together with the sprue part in the substrate holding part.
- the embodiment according to subclaim 17 has the additional advantage that stresses in the substrate are largely avoided during the separation process.
- any dust that is produced is sucked off when the sprue part is broken off and is thus kept away from the area of the injection mold.
- the invention is to be explained in more detail below on the basis of exemplary embodiments and with reference to FIGS. 1 to 10.
- the exemplary embodiments relate to the production of optical data carriers such as CD, DVD, OBC or the like. Nevertheless, the idea of the present invention is not limited to this.

- a mold release sleeve 14 and an ejector needle 16, which passes through the central part 15 of the movable mold half 3, are arranged so that they can be pressurized with pressure medium.
- a piston 17 in a hydraulic cylinder 18 can be pressurized by means of pressure media, not shown here, so that the piston rod 19 moves the ejector needle 16 forward.
- a return spring 20 when the pressure is released, the ejector needle 16 is pulled back into its starting position.

- the part 29 of the sprue part 11 has a bevel 31 in its front area, with which a secure centering of the substrate together with the sprue part 11 in the substrate holding part 23 is ensured.
- the part 29 of the sprue part 11 has in its cylindrical region 32 adjoining the bevel 31 a diameter which is smaller by a few hundredths of a millimeter (generally between 0.02 mm and 0.05 mm) than the inside diameter of the substrate holding part 23 in this area.
- the substrate holding part 23 has a section 33 which forms a flat contact surface 34 with the substrate 10 and in which runs a vacuum channel 35 which is connected to a vacuum pump (not shown here). With the sprue 11, the substrate 10 is fixed in the direction of movement of the lever 24 and by the negative pressure in the vacuum channel 35 in the direction perpendicular thereto.
