Abstract

PURPOSE:To prevent damage of the master model due to spotting and facilitate spotting by suspending a master model on a slide etc. keeping specified distance and allowing free movent in the direction of spotting. CONSTITUTION:A slide 4 is lowered by a pressure cylinder, and a master model 1 is brought closed to a forming die 12. When the master model 1 comes into contacts with the forming die 12, the master model floats up with a bedplate 7 and slides along a sliding guide 8 and leaves the stopper 10. Then, spotting is performing with the forming die 12 by the weight of the master model 1. The length of the sliding guide is made long enough to keep the bedplate 7 at sufficient distance from the lower face of the slide 4. At this time, a touch switch 13 operates and the pressure cylinder is stopped, and the slider 4 is stopped above the bedplate 7. At the same time, a contact detection lamp is lit up.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mold matching device for targeting molds of automobile parts and the like.

Gypsum, resin gypsum, etc. are used as master models for manufacturing molds for automobile parts, etc. due to ease of molding. The mold is assembled by coming into contact with the mold set on the bed surface. However, in order to manufacture molds for a large number of parts, the settings for the slide position control are different for each one, and due to setting errors and allowable machining errors of the molding mold, overtravel of the slide can occur. The master model, which has low strength, is often pressed and damaged, which is rare. The master model usually has a complex three-dimensional shape and is finished with a high precision surface, so it takes a lot of time and effort to reshape the master model, and there is a risk of damage to the master model. The device was desired.

The present invention has been made in view of the above-mentioned points, and is designed to prevent damage caused by pressing the master model against the molding mold with an excessive pressure due to mistakes in the positioning of the master model, etc. To provide a mold matching device for mold manufacturing that can easily match a master model to a mold for molding and is easy to operate.

The present invention will be explained below using examples.

FIG. 1 shows an example of a real door of the present invention, in which a master model 1 is installed in a press device 2, and the molds are matched by the master model 1 itself. Master Mochi/I/1
is suspended from the lower surface of a slide 4 which can be raised and lowered by a cylinder 3 of the Plen apparatus 2 via a hanging table 5 which can be freely removed from the film. Master model 1 is the original form for molding the desired parts of the JR Kurumawa) Shinasato.It is formed into the desired shape with plaster or resin gypsum, etc., and the surface is coated with the specified coating, and The guide hole 9r is fitted into the sliding guide 8, which is installed vertically at the end of the hanging table 5, so that it can slide up and down vertically. , is adapted to be suspended by being engaged with a resting portion 1o at the lower end of the sliding guide 8. The length of the sliding guide 8 is such that the base plate 7 is kept at a sufficient distance from the bottom surface of the slide 4, and the overtravel of the slide 4 is determined by the bolster 11.
Molding metal m12 that has been subjected to the specified processing and placed on the mold and molded.
Avoid pressing the master model l with excessive pressure, and the weight of master mochi'lv1 will cause 41! I am trying to match it. 13 is a touch switch that detects when the master mochi/I/1 comes into contact with hV and the mold 12 and floats, sends a stop signal to the pressurizing cylinder 3, and lights up the contact detection lamp 14. I try to do that.

Numeral 15 is a breakage prevention switch, which is activated when the master mochi/I/1 slides a predetermined amount.
After emergency stop, switch to the upper row direction and press master mochi) L/l to prevent damage.

However, when it comes to matching Master Mochi/L/1,
The hydraulic power source (not shown) is operated to move the pressure cylinder 3 downward, and the slide 4 is lowered to move the master mochi/L'l.
approaches the molding die 12.

When the master model 1 comes into contact with the molding die 12, the second
Master mochi/L/ 1 td sliding guide 8 as shown in the diagram
I fluttered as if I was floating along the line, and left the resting area.
The master mochi tv 1 is fitted into the molding die 12 by its own weight. At this time, the touch switch 13 is activated to stop the pressure cylinder 3 and stop the slide 4 at a position sufficiently far above the base plate 7 to prevent excessive pressing force from being applied to the master mochi/I/1. It's something that doesn't exist. Therefore, as in the past, J'l^' is used as a master model with low strength due to a mistake in the setting of Suride. Since it will not be damaged by applying a large pressing force, and it does not require the slide positioning settings that are available in the master model, the master model as described above can be used even when manufacturing a wide variety of molds. The molds can be easily matched by simply lifting and lowering the mold into the mold, and the desired mold can be manufactured. Note that the contact detection lamp 14 is turned on via the touch switch 1B.
Eye 1. Check the master model 1 with the mold 1.
It can also be molded into 2.

FIG. 3 shows another embodiment of the present invention, in which an elastic member 16 such as a coil spring with a predetermined elastic force that does not damage the master mochi/L/1 is attached to the sliding guide 8, and the base plate 7 is The master mochi/L/1 is pressed with a predetermined force through the mold to match the shapes.

In this example, since the master model can be pressed against the molding die with a predetermined force, the master model can be reliably brought into contact with the molding die during mold matching, and the degree of contact can be accurately confirmed. It can be used to make molds.

It should be noted that the elastic material may have a predetermined elastic force, and a mold may be provided in place of the master model to be used for applying pressure.

In the embodiments described above, elastic members such as coil springs having different strengths may be arranged in series so that they can be sequentially pressed more strongly as the mold matching progresses.

In addition, as shown by the dotted line, the master model/L/1 is supported on the slide 4 by a predetermined elastic tool 17 so as to cancel out the weight of the master model, and the master model 1 or the molding metal F1 is
2, the molds can be matched without impact. In this dormitory example, the speed at which the master model is approached for mold matching can be increased, speeding up the work.

In the above example, the master model was slid on the slide via a sliding guide, but in order to increase the accuracy of vertical movement and to ensure smooth sliding, a guide bushing of a predetermined length was fitted. This can be done as appropriate, such as by using parallel link mechanisms, linear bearings, etc. in parallel.

Although the above embodiments have been described with respect to automobile parts, the present invention can be similarly applied to parts in other fields.

In addition, although the master model was installed in a press device that can mold parts, it can also be installed in other lifting devices.

As described above, in the present invention, the positioning of the master model can be fixed even in mold manufacturing where the master model is pressed with a large pressing force such as a slide and damaged due to a setting error in the positioning of the master model. No special settings are required,
It can be easily matched and molded.
