Description

Jig device for mold inserts

The present invention relates to a jig for inserting a mold, and more particularly, to a jig for inserting a mold, in particular, a mold is fixed using a magnet switch, a connecting member made of a stretchable material is connected to a wire having no elasticity, So that the gap can be easily inserted into the engagement hole of the fine dice.

Generally, the bolt manufacturing process is performed in the order of forging, wire rolling, heat treatment, plating, and shipment of the wire-shaped raw materials. In the first process, the forging machine is replaced.

The forging machine is provided with dies and punches as shown in FIGS. 6 (a) and 6 (b). In the forging process, the dies coupled to the dies are composed of up to four stages (four) Cutting is performed in the first stage, preforming is performed in the second stage (nose side chamfering), and bolt molding is performed in the third and fourth stages.

Depending on the case, it is sometimes necessary to change the mold twice or three times a day, and the mold replacement time is about 2 hours to 2 hours and 30 minutes, and thus the production amount is decreasing.

The mold demolding process and the mold clamping process will be briefly described below.

First, the mold disassembling process is performed by performing a step of loosening the bolt, extracting the cutting knife and the clamp of the die and the punch of the die, manually removing the mold of the die and the punch and then removing the oil, Is performed.

In the mold clamping step, a step of inserting the prepared mold into the die is performed, a step of tightening the primary bolt of the die is performed, a step of tightening the bolt after the cutting knife and the clamp are fastened to the punch, A step of adjusting the length of the die and the center of the punch die and then a step of tightening the second bolt is performed and a step of visually confirming through the production of a test sample is performed, And then performing the producing step.

The standard of the mold is slightly different, but the basic weight corresponds to about 6 ~ 10kg each. In order to replace the mold, the mold is manually removed and inserted. Although the weight of the mold is not so heavy, it is difficult to carry out the work by the operator, and since the mold is grease, it is slippery and there is always a risk of safety accident due to the fall of the mold have.

In addition, since the gap between the die hole and the mold is very small (about 0.04 mm), it is difficult to insert the straight line in the die insertion operation, so that the operator moves little by little do. That is, if the mold can not be moved up and down without being stretched, it is not suitable for such a work.

1 is a view for explaining a jig for inserting a mold according to the present invention. FIG. 2 is a view for explaining a connection relation between a magnet switch and a safety band according to the diameter of a mold. FIGS. 3 and 4 are views for explaining a main support and a sub support to which the mold inserting jig apparatus according to the present invention is coupled.

1 and 2, a jig for inserting a mold to which the present invention is applied includes a plurality of molds 300 coupled to a plurality of mold coupling grooves, and a plurality of molds 300 are coupled to the mold coupling grooves while moving the molds 300 up and down. .

A main supporting body 110 in which both side lower portions of the mold inserting jig apparatus 100 are bent inward and spaced apart from each other at a predetermined interval and the center of the lower end surface is opened, A plurality of engaging parts 130 attached and fixed to both ends of the lower end of the sub support 120 and a plurality of engaging parts 130 which are slidably coupled to the main support 120, ) Into the mold engaging grooves, respectively.

A first connecting member 142 whose one end is connected and fixed to the center of the protrusion 141a and a second connecting member 142 whose one end is connected and fixed to the center of the protrusion 141a; A support member 144 connected to the center of the second connection member 143 and partially opened at the lower end thereof and a lower end opening And a safety belt 146 which is connected at both ends to the lower end curved surface of the support table 144 and fixes the metal mold 300 to the magnet switch.

The magnet switches 146 are tapered inwardly so that the inner side facing each other has a certain inclination angle. As a result, as shown in FIG. 2, the magnet 300 is easily coupled to the magnet switch 145 irrespective of whether the diameter of the mold 300 is large or small.

Since the first connecting member 142 is made of a non-stretchable material and the second connecting member 143 is made of a stretchable material, when the mold 300 is inserted into the mold engaging groove, the mold is easily moved up and down .

A plurality of engagement holes 111 are formed at both sides of the main support 110 of the mold inserting jig 100 according to the present invention at regular intervals, 111 so that the fixing portion 141 is fixed at the current position.

A pulley 148 is provided at a position opposite to the curved surfaces on both sides of the projection 141a of the fixing portion 141 so that the fixing portion 141 can be moved forward or backward. (148) is movably coupled to the pulley rail (112) of the main support (110).

The operation of the above-described jig for inserting the mold will be described below.

As shown in FIGS. 1 to 4, first, a fixing magnet switch 121 provided at both ends of sub-supports 120 positioned in parallel with each other at opposite ends of a main support 110 is inserted into a mold 300 (Or punch) to attach and fix the die-inserting jig device 100 to the die.

The pulley 148 provided on the fixed portion 141 is slidably installed on the pulley rail 112 of the main support 110 and then the fixed portion 141 is moved along the pulley rail 112 to a desired position The spring plunger 147 provided on the fixing part 141 is inserted into the corresponding coupling hole 111 of the main support 110 and is engaged. That is, the "A" portion of FIG. 1 is slidingly coupled to the "B" portion of FIG.

When the mold insert part 140 is coupled to the main support 110, the mold 300 is placed in the mold insertion type magnet switch 145 as shown in FIG. At this time, the mold 300 is positioned to be positioned inside the safety belt 146, and the mold 300 is attached and fixed to the mold-insertion-type magnetic switch 145 by electromagnetic force, but is prevented from falling downward by the safety belt 146 . The safety belts 146 are provided on both sides of the support base 144 to support the mold 300 in a balanced manner.

At this time, the support 144 is connected and fixed to the center of the projection 141a of the fixing portion 141 by the first connection member 142 and the second connection member 143, The mold 300 can be finely moved up and down when the mold 300 is inserted into the mold coupling hole. Even if the gap between the mold coupling hole and the mold is extremely small (about 0.04 mm) So that the mold 300 can be inserted.

Since the mold switch magnet 145 for lifting the mold 300 has a tapered shape, that is, a "V" shape inward, the mold 300, which is in line contact with the magnet switch for inserting the mold 300, Quot; B "point as shown in Fig. 2 and the small "A" point when the mold 300 is small. At this time, the portion where the magnet switch for inserting the mold 145 and the mold 300 are in contact can have a certain shape. 5, protrusions having a sharp or rounded shape may be arranged at regular intervals in a portion of the magnet switch for inserting the mold 145 that is in contact with the mold 300. These protrusions may be in contact with the mold 300 So that the frictional force of the joint surface can be improved and the mold 300 can be prevented from sliding from the mold insert magnet switch 145.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or essential characteristics thereof. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
