Signing of the mold injection molding equipment.

摘要

The present invention relates to a mold clamping device for quickly mounting or detaching each mold mounted on a fixed die and a movable die constituting an injection molding machine, and more particularly, a permanent magnet on a mold fixed surface of the fixed die and a movable die. And a magnet panel having a core in which the permanent magnet is wound and arranged, and a mold clamping device of an injection molding machine, which is equipped with a magnet panel which amplifies a magnetic field by a power source applied to the core and fixes the mold. Regarding, A mold die 1 composed of a movable die 2 installed to slide by a tie-bar and a hydraulic cylinder, and a fixed die 3 provided at a point corresponding to the movable die 2; And a clamping device provided with a magnet plate 10 as a fixing means for fixing the mold 4 including the movable mold 4a and the fixed mold 4b to the mold die 1; In the injection molding machine consisting of; a melter having a nozzle 40 for melting and supplying the injection raw material to the fixed mold (4b), The front portion of the mold die (1) is provided with a receiving portion (5) in which the magnetic plate 10 is accommodated, The magnetic plate 10 includes a magnetic conductor 11 vertically and horizontally mounted on the front surface of the main body 10 ', a permanent magnet 12 in close contact with the rear surface of the magnetic conductor 11, and the permanent magnet ( A core 13 wound around 12 and another permanent magnet 14 mounted diagonally in the side portion of the magnetic conductor 11, and each of the magnetic conductors 11 is made of synthetic resin, foam, silicone, etc. The nonconductive object 15 is filled. The non-conductive material 15, which is filled and fixed between the magnetic conductors 11 on the front surface of the magnetic plate 10, has a shape of the recessed groove 16 to a depth of 0.3 to 0.5 mm from the surface of the magnetic conductor 11. It provides a mold clamping device of the injection molding machine formed by forming the discharge line 17 to reduce the work time for the removal / attachment of the mold, and reduce the installation error that can occur between the two molds generated during mounting To ensure that
