Abstract

The present invention relates to a digital counter mounted on a mold, which comprises: a housing; a pin disposed on the housing to be movable in a forward direction and a backward direction; an elastic member disposed between the pin and the housing to have a restoring force when contracted; a switch unit which is in contact with the pin and is turned on and off in response to the movement of the pin in the forward direction and the backward direction; and a magnet disposed at the front end of the pin; and a controlling unit connected to the switch unit. The pin moves forward with the mold by the magnetic force of the magnet in a state in which the pin does not protrude beyond the housing, and the controlling unit counts the number of times the switch unit is turned on or off by moving the pin in the forward direction and the backward direction. In an embodiment, a sealing member is disposed between the head of the pin and an outer surface of the housing to prevent mold-cooling water or hot oil from flowing into the housing.

Description

Digital mold counter and management system having the same

The present invention relates to a digital counter, and more particularly, to a digital counter and a digital mold management system for counting the number of times a mold is used by detecting the movement of a pin including a magnet attached to a mold.

Since mold loses precision after long-term use, it is important to keep track of the number of times it is used. A digital counter is a device that detects and informs the number of times the mold is used electrically. The digital counter is mounted on the mold and senses the movement of the mold, so that the number of times the mold is used can be counted.

Republic of Korea Patent No. 10-1183283 (published on September 14, 2012) describes a configuration in which the pin is pushed into the case by the mold, and the movement of the pin is counted by accumulating the number of times the mold is used through the photodetector.

However, such a counter has a structure in which the pin in contact with the mold always protrudes out of the housing. Therefore, there is a high risk that the pin is damaged or malfunctioned by an obstacle or an external force.

In addition, since the pin has a structure that directly receives a load by being pressed against the mold, there is a high risk of damage to the pin and the elastic member supporting the pin so that the number of times of use of the mold can be accumulated.

In addition, in the case of a digital counter, it is important to check the battery duration and the state of the battery because the power must be maintained. If not, it is difficult to accurately count the number of times the mold is used.

10 is a view showing the state of the pin 200 and the switch unit 400 before the mold is operated.

10, before the mold 1 operates, the pin 200 rotates the lever 420 of the switch unit 400 while the head 220 is pushed backward due to the elastic member 300, The lever 420 presses the contact switch 410 . In this case, the control unit 600 recognizes the switch unit 400 as an ON state. Since the pin 200 is pushed backward by the elastic member 300 , the magnet 500 does not protrude out of the housing 100 and is located inside the boss 121 . Therefore, there is no risk of the pin 200 being damaged by an obstacle or an external force or malfunctioning.

11 is a view illustrating the state of the pin 200 and the switch unit 400 when the mold 1 operates and faces the digital counter 10 .

Referring to FIG. 11 , the mold 1 operates to move the mold 1 backward toward the pin 200 , and the mold 1 comes into contact with the magnet 500 . Even if the mold 1 comes into contact with the boss 121 first, the magnet 500 can overcome the restoring force of the elastic member 300 by magnetic force and contact the mold 1 . At this time, the pin 200 is in a state in which the head 220 is pushed backward due to the elastic member 300 . Since the lever 420 is pressed by the pin 200 , the switch unit 400 is in an ON state.

12 is a view showing the state of the pin 200 and the switch unit 400 when the mold 1 operates and moves away from the digital counter 10 .

Referring to FIG. 12 , when the mold 1 moves forward so as to be away from the digital counter 10 while in contact with the magnet 500 , the magnet 500 is magnetically fixed to the mold 1 . Therefore, the pin 200 also overcomes the restoring force of the elastic member 300 together with the mold 1 and moves forward. When the pin 200 moves forward, the lever 420 that pressed the contact switch 410 rotates with a restoring force, and the contact switch 410 is converted to an OFF state, and the control unit 600 recognizes this. and count the number of times. In this case, the number of times is defined as the number of times of use of the mold 1 once.

In a state in which the mold 1 continues to move forward, when the elastic member 300 reaches the contracting limit, the forward movement of the pin 200 is limited, so the magnet 500 overcomes the magnetic force and the mold 1 ) is separated from

When the magnet 500 is separated from the mold 1, the pin 200 is pushed backward by the restoring force of the elastic member 300, and as shown in FIG. The lever 420 is rotated again, the lever 420 presses the contact switch, and the switch unit 400 is switched to an ON state.

When the mold 1 moves backward again, this process is repeated, and the number of times is accumulated and counted. Since the pin 200 is moved by being attracted to the mold 1 by magnetic force, the pin 200 does not directly receive the load pressed by the mold 1, and the pin 200, the elastic member 300, and the switch unit 400 ) has the advantage of preventing damage and extending the lifespan.

13 is a view showing the display unit (D).
