Abstract

(57) [Summary] [Purpose] To make it possible to easily count the number of times the mold is operated. [Structure] A mold 1 was incorporated with a counter 4 for integrating the number of times of opening and closing. [Effect] Since the number of times of opening and closing of the die itself is integrated and displayed, it is not necessary to indirectly calculate the number of times of opening and closing from the number of times of operation of the machine and the management of the repair time and the like becomes easy.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mold used for resin molding, metal pressing and the like.

[0002]

[Prior Art]

 Machines that use dies, such as resin molding machines and metal press machines, are generally equipped with a counter that counts the number of times they are operated, and the accumulated values are used as management data for periodic machine inspections. There is. However, conventionally, the mold itself is not provided with a counter for multiplying the number of times of operation, and the number of times the machine operates when the mold is used is sequentially recorded, and this is totaled to record the number of operations of the mold. Since the number of operations was calculated indirectly, it took a lot of trouble to manage the repair time of the mold, which was troublesome.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of such a point, and an object thereof is to solve the above problems by making it possible to easily count the number of operations of the mold itself.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a structure in which a mold is incorporated in a mold that operates every time opening and closing are repeated to accumulate the number of times of opening and closing. As the above-mentioned counter, for example, a counter composed of a pair of units, such as a magnet type counter, which is activated each time the mating is repeated and accumulates the mating frequency, is used. Each unit is a pair of molds. It is installed by corresponding to the facing surface of each.

[0005]

[Action]

 Each time the mold is opened and closed, the integrated value of the number of times the mold itself is opened and closed is displayed, so there is no need to indirectly calculate from the number of times the machine has been operated, and management becomes easier.

[0006]

【Example】

 Next, an embodiment of the present invention will be described. FIG. 1 is a schematic perspective view of an embodiment, in which 1 is a resin molding die consisting of a pair of an upper mold 2 and a lower mold 3, and 4 is a magnet type coun consisting of a main body 5 and a magnet portion 6. It is. This counter 4 has a display unit 5a and an operating mechanism for operating the display unit 5 on the main body 5, and each time the magnet unit 6 approaches or contacts the main unit 5, the operating mechanism senses this and the numerical value of the display unit 5a becomes 1 It has a structure that increases in increments of count, and commercially available products can be used as they are. Illustrations of parts such as cavities not directly related to the invention are omitted.

The counter 4 has mounting recesses 2 a and 3 a formed on the surfaces of the upper mold 2 and the lower mold 3 facing each other, and the main body 5 and the magnet portion 6 are fitted into the recesses 2 a and 3 a, respectively. It is fixed by an appropriate means in a state of being exposed on the surface of No. 3, and the main body 5 and the magnet portion 6 come close to or come into contact with each other when the mold 1 is clamped.

For this reason, when the mold 1 is attached to a resin molding machine and used, the main body 5 and the magnet portion 6 approach or contact each time the mold is clamped, and the numerical value of the display portion 5a of the main body 5 counts as 1. Even if the mold 1 is removed from the molding machine after finishing the work, the displayed value remains as it is unless the reset operation is performed, and the number of times of opening and closing at that time is sequentially added up each time it is used for molding, The total number of times the mold 1 is opened and closed is displayed on the display unit 5a. Therefore, unlike the conventional case, it is not necessary to indirectly calculate from the number of times the machine operates, and the mold 1 can be managed by using the displayed value as it is.

Although the magnet type counter is used in the embodiment, a counter of another type other than the magnet type can be used by appropriately incorporating it in a mold according to its structure. Further, the mold is not limited to resin molding, but may be a mold for other uses such as metal pressing, and the present invention can be applied to various molds.

[0010]

[Effect of the device]

 As is apparent from the above-described embodiment, the mold of this invention incorporates a counter that counts the number of times of opening and closing, and the counter displays the total number of times of opening and closing of the mold itself. There is no need to indirectly calculate the number of times of opening and closing based on the number of times of operation, etc., which has the advantage of facilitating management such as repair time.
