Definitions
- the invention relates to a device for molding objects in a cavity, which is at least partially formed by an insert in a mold plate.
- objects are filled by filling a cavity in a mold z. B. made with thermoplastic materials.
- this molding process must be monitored.
- the filling operation is controlled so that an initially speed-controlled phase is followed by a pressure-controlled phase which lasts until the end of the filling process.
- the filling situation achieved in which the mold cavity is completely wetted with plasticizable mass, the internal pressure of the interior of the mold cavity is still relatively low.
- Process monitoring and process control uses pressure and temperature sensors installed in the injection mold so that the front of the sensor touches the plastic part to be produced. Such an arrangement is described, for example, in DE 101 14 228 A1. For the measurement of piezoelectric signals usually highly insulating lines are used.
- the present invention is based on the object, a device of o. G.
- sensors in particular for pressure and temperature, can also be used in tools in which the cavities are formed by inserts.
- the clutch itself is designed as a quick coupling without locking.
- the easiest way is likely to be a plug-in coupling, in which a plug is inserted into a box. If the sensor is located very close to its coupling part, an extra line is unnecessary. As a rule, however, the sensor should be connected to its first coupling part via a line, while the second coupling part is followed by a line, for example, to a connection to a signal evaluation unit.
- the senor is a cavity internal pressure sensor.
- care must be taken to ensure that the cables are highly insulating, since even there a touch of a finger due to finger swelling is sufficient to remove the insulation.
- these lines have a resistance of at least 10 12 ohms.
- WO 02/082023 A1 proposes, for example, a method for automatically detecting the sensitivity of sensors, in which the sensor is assigned a resistance of a specific size, by means of which the sensor is assigned to a specific sensor group having a predetermined sensitivity range. That is, the sensitivity of the cavity pressure sensor is encoded by means of a resistor. For this information, an additional line must be provided in the present invention and also decoupled.
- a temperature sensor is disposed in the insert.
- the clutch must be for this
- thermocouple made of the same material as the thermocouple itself.
- thermocouple There are various material compositions for a thermocouple. Only, for example, the composition of nickel / chromium / nickel is mentioned. If such a thermocouple is selected, then the line should be made of the same material. Incidentally, with the present invention, not only highly insulating piezoelectronic lines but also lines not highly insulating can be separated.
- Figure 1 is a partially cross-sectional side view of a mold
- Figure 2 is a plan view of a sensor arrangement according to the invention.
- an injection mold P has a fixed mold plate 1 and a movable mold plate 2. Both plates 1 and 2 are each associated with a stationary platen 3 and 4, wherein between the platen 4 and the movable mold plate 2 is still a means 5 for moving the movable mold plate 2 is provided.
- a trough 9 is formed, which forms a mold cavity or a cavity 12 with a core 10, which protrudes from an insert 11 in the movable mold plate 2.
- the insert 11 is also removably seated in a recess 13 in the movable mold plate 2 and is held there by fastening bolts 14.1 and 14.2.
- a stepped bore 15 is formed, in the front region of a sensor 16 is seated.
- a sensor front 17 is seated in the plane of a cavity inner wall 18. This forms the surface of the core 10.
- the sensor 16 is connected via a line 19 with a first coupling part 20, which forms a quick coupling 23 with a second coupling part 21, which sits in a bore 22 in the movable mold plate 2.
- the second coupling part 21 is connected via a line 24 to a fixed terminal 25, to which then a signal evaluation unit not shown in detail is connected.
- the quick coupling 23 is a plug-in coupling.
- the first coupling part 20 forms a socket into which a plug 26 of the second coupling part 21 can engage.
- a ringwall 27 secures a connection in the box.
- the senor 16 is inserted into the stepped bore 15 of the insert 11, so that the sensor front 17 is in the plane of the cavity inner wall 18.
- the sensor 16 is connected via the line 19 with the first coupling part 20, the can opening is located approximately in the plane of the insert base 28.
