[0048] figure 1 It is explanatory drawing of 1st Embodiment of this invention. It is cut along the longitudinal direction and shows the injection part and the mold part of the injection molding machine 10 from the horizontal direction. A metal mold 16 for forming is mounted on the fixed plate 14 . In addition, an actuator 44 for adjusting the position of the injection nozzle 18 in the vertical direction and an actuator (not shown) for adjusting the position of the injection nozzle in the left-right direction are provided on the injection unit 12 .

[0049] In addition, as the distance measuring mechanism 22, the optical displacement sensor 26 mounted on the turntable 24 and the reflecting plate 28 overlap with the inner peripheral surface of the positioning ring 34 serving as the reference surface 32 of the sprue hole of the mold so that the measuring axis 30 overlaps. way set on the metal mold face. The distance measuring mechanism 22 is installed so that the rotation axis...

[0071] Figure 8 It is a second embodiment of the present invention, and is a schematic diagram of an example of centering the mold sprue hole 38 and the injection nozzle hole 19 using one distance measuring mechanism 22 and a mechanism for measuring the rotation angle of the distance measuring mechanism 22 . The basic structure is substantially the same as that of the first embodiment, but the rotating table 24 outputs the rotation angle data (distance, angle data 72) of the distance measuring mechanism 22, and controls the display device 42 (refer to figure 1 ) simultaneously monitors the rotation angle data and the measured distance data measured by the distance measuring mechanism 22 .

[0072] First, the measuring axis 30 of the distance measuring mechanism 22 is made to overlap the reference surface 32 of the sprue hole of the mold, and the distance measuring mechanism 22 is rotated. The control display device 42 simultaneously monitors the intersection point of the mea...

[0077] Figure 9 This is the third embodiment of the present invention, and is a method of centering the positioning hole 106 of the fixed disk 14 and the hole of the injection nozzle 18 . Figure 9 It is a figure which cuts the injection part and the mold part of the injection molding machine 10 along the longitudinal direction, and shows it from the horizontal direction. In addition, the injection unit 12 is provided with an adjustment bolt 122 for adjusting the position of the injection nozzle 18 in the vertical direction, and an adjustment bolt (not shown) for adjusting the position of the injection nozzle 18 in the left-right direction.

[0078] In this embodiment, displacement sensors 1 and 2 are used as distance measuring means (see Figure 10 ) is rotatably installed on the mold mounting surface 110 of the fixed disk 14 via the rotating tables 120 and 120 . The displacement sensors 1 and 2 may be contact displacement sensors or non-contact displacement sensors such a...

Abstract

The invention provides an injection molding machine and a centering method of the same. An optical displacement sensor and a reflection plate, which are mounted on a rotatable table, are arranged on a mold to orient the measurement axis thereof to an inner peripheral surface of a centering ring as a reference surface of a gate of a mold. A distance measuring device is located where the rotational axis of the rotatable portion is not coincident with the central axis of the sprue opening of the mold. The rotational axis of the distance measuring instrument is adjusted so that the measurement axis of the distance measuring instrument does not intersect with the central axis of the sprue opening of the mold. Then, the center opening of the injectors is found with reference to the center of the sprue opening of the mold in which it is the intersection of the two axes. Furthermore, the position of the injection nozzle is adjusted so that the two center points are congruent.

Description

technical field [0001] The present invention relates to an injection molding machine, and more particularly to an injection molding machine equipped with a centering adjustment mechanism for an injection nozzle and a centering method for an injection nozzle. Background technique [0002] In the injection molding machine, the injection nozzle of the injection unit is crimped on the sprue sleeve of the metal mold installed on the fixed plate, and the injection nozzle is injected into the metal mold through the sprue hole of the metal mold provided on the sprue sleeve. Hole injected molten resin. Therefore, it is necessary to align the axial centers of the sprue hole of the mold and the hole of the injection nozzle, and perform centering and alignment adjustment work of the nozzle hole of the injection nozzle and the sprue hole of the mold. [0003] Generally, the centering of the injection nozzle is adjusted by bringing the nozzle hole of the injection nozzle close to the spr...
