Abstract

PURPOSE:To stop a die clamping operation before die clamping is ended, by sliding a die plate opposed to a die plate having an insert metallic fixture holding part, by giving the necessary minimum pre-pressure in the clamping direction and a necessary stroke to the back. CONSTITUTION:A necessary stroke 10 is given to a die plate 1 by a hanger 8, the hanger 8 and a driving unit 9 are attached to a fitting plate 7 so that the necessary smallest force can be given the die clamping by the driving unit 9, and when the die clamping has been completed, a stroke 10 becomes zero. Also, as for the other die plate 2, an insert metallic fixture 5 is held by an insert metallic fixture holding part 6, and a sensor 3 is integrated into a parting line 4. In case of a die clamping operation, if a foreign matter is mixed into the parting line 4 due to an omission, etc., of the insert metallic fixture 5 and the die plates 1, 2 do not contact closely to each other, a die clamping stop signal is outputted by the sensor 3, and a forming machine stops completely its operation within the stroke 10. In this way, a metallic die can be prevented from being damaged.

Description of the Related Art Conventionally, this type of insert molding mold uses a sensor 3 incorporated in the mold parting line 4 to detect minute differences between the mold plates 1 and 2 when the mold clamping operation of the molding machine is completed, as shown in FIG. It was configured to detect distance.

た。Problems to be Solved by the Invention However, with this configuration, if the insert fitting 5 falls off from the holding part 6 at the mold parting line 4, the sensor 3 detects this and immediately stops the mold clamping operation of the molding machine. However, the response is not fast enough, and the mold clamping unit of the molding machine applies clamping force to the mold due to inertia, resulting in damage to the mold part/grine.

作を停止できる。Means for Solving the Problems The technical means of the present invention for solving the above problems is to set a sufficient clearance behind the mold plate that is slidably mounted in the mold clamping direction, and to attach the insert metal fittings. By incorporating a drive unit that can variably set the force necessary and sufficient to bring the parting line into close contact when the parting line does not fall off,
This allows the parting line to come into close contact with the molding machine before the mold clamping operation is completed, and if the insert fitting falls out of the holding position and enters the parting line, it will be detected by a sensor and the molding will be stopped immediately. The mold clamping operation of the machine can be stopped.

ラインにはセンサー３が組込まれている。In FIG. 1, the mold plate 1 is given a stroke 10 by the hanger 8 and is subjected to the minimum force necessary for mold clamping by the drive unit 9. The hanger 8 and the drive unit 9 are attached to the mounting plate 7. When the mold clamping is completed, the stroke 1o becomes zero. An insert metal fitting 5 is held in an insert metal fitting holding part 6 on the template 2, and a sensor 3 is incorporated in the party/grain.

The mold plate 2 does not come into close contact with the mold plate 2, a mold clamping stop signal is generated from the sensor 3, and the molding machine then completely stops within 1° of operation.

を有する。Effects of the Invention The present invention provides mold clamping in a slidable state by applying the minimum necessary preload in the mold clamping direction and the required stroke behind the mold plate facing the mold plate having the insert metal holding part. Even if a foreign object such as a fallen insert fitting gets into the parting line, it can be detected by a sensor built into the parting line and the mold clamping operation can be stopped before mold clamping is completed, so there is no chance of damage to the mold. This has the effect of greatly reducing mold repair costs and minimizing production downtime.
