Description
Technical field
The utility model relates to a kind of die production technical field, specifically is a kind of external combination induction coil.
Background technology
At present, for solve injection moulding produce in product best bright finish, short penetrating and quality problems such as weld mark, use the die cavity heating technique usually and solve.Injection moulding die cavity heating technique can roughly be divided into high-temperature steam heating and electrical heating two big classes.The Steam Heating technology; Need in mould, to lay heating pipe line in advance, the flow of steam at high temperature through mould inside flows through heats with heat exchange pattern mould; Heating process is for from inside to outside; Be characterized in: 1) need design arrangement heating pipe line in advance, 2) the heating and cooling time lengthening, because of also being similarly from inside to outside, its cooling carries out.Induction heating technique then is " kelvin effect " of utilizing high-frequency induction heating; Adopt the induction coil of mating die cavity shape; High frequency electric through flowing through coil heats the injection moulding cavity surface; Be characterized in: 1) heating is short cool time, is heated 2 because of it only has cavity surface) a special-purpose coil of cavity surface shape preparation.
Therefore, induction heating technique is compared the Steam Heating technology, has certain superiority; But every pair of mould all need rise and fall according to the cavity surface shape; The preparation special induction coil, or the coil poor effect of preparation also can only be prepared a new coil when needing local adjustment again; For production application has brought inconvenience, limited its scope of application.
The utility model content
The utility model provides a kind of external combination induction coil to the above-mentioned deficiency that prior art exists, and makes its coil do corresponding the adjusting according to the surface undulation of die cavity, and can be adjustable to local temperature in the coil scope.
The utility model realizes that through following technical scheme the utility model comprises: framework be connected it on and equally distributed some sensing units.
Described sensing unit comprises: base, governor motion and coil block, wherein: coil block is fixed on the top of base, and base is connected on the framework through governor motion.
Described governor motion comprises: knob, bolt and bayonet lock, wherein: bolt connects base and framework and one of which end and is stuck in the bottom of base by bayonet lock, and the other end is provided with knob.

Embodiment
As shown in Figure 1, on present embodiment comprises framework 1 and is connected it and equally distributed some sensing units.
As shown in Figure 2, described sensing unit comprises: base 2, governor motion and coil block, and wherein: coil block is fixed on the top of base 2, and base 2 is connected on the framework through governor motion.
Described governor motion comprises: knob 3, bolt 4 and bayonet lock 5, wherein: bolt 4 connects bases 2 and framework 1 and one of which end and is stuck in the bottom of base 2 by bayonet lock 5, and the other end is provided with knob 3.
Described coil block comprises: the induction coil 6, electrode 7 and the power line 8 that connect successively.
Described electrode 7 comprises: first electrode and second electrode, wherein: the length of first electrode is greater than the length of second electrode.During use, when required heat was big, power supply was connected on first electrode; When required heat was little, power supply was connected on second electrode.
Described power line 8 is arranged on the inside of base 2, and an end links to each other with electrode 7, and the other end stretches out below base 2.
Described base 2 is a rectangular configuration.
Like Fig. 3 and shown in Figure 4, during operation, rotation knob 3 is regulated the length that bolt 4 stretches out, thereby it is far and near with the distance of die face 9 to be heated to regulate each induction coil 6, makes this distance identical, thereby makes die face 9 be heated evenly.
