Description

[Detailed description of the invention] [Industrial field of application] The field of industrial application of the present invention is molding machines such as die casting machines and injection molding equipment.
This invention relates to a mount device for a molding machine that prevents burrs, cleaning agents, mold release agents, etc. from adhering to products that fall due to failure in product ejection.

[Conventional technology]

The second operation of the conventional molding machine before and after taking out the product
As shown in FIG.

In both figures, the symbol 1 is the machine base, and a fixed platen 2 is fixed on the upper side of the machine base.
Opposed to this, a movable platen 3 is movably mounted on the machine base.

Also, although not shown, a mold clamping and opening mechanism and an end platen are fixed behind the movable platen 3, and four columns (not shown) are provided between the end platen and the fixed platen 2. are connected together.

A fixed mold 4 is fixed on the fixed platen 2 side,
A movable mold 5 is fixed on the movable platen 3 side opposite to the movable platen 3.

The state shown in FIGS. 2 and 3 is the mold open state, and FIG. 2 shows the state immediately after the mold is opened.

Immediately after the mold is opened, the product 6 is attached to the movable mold 5 side.

A product ejecting device 7 is guided between the fixed mold 4 and the movable mold 5, and the product 6 is chucked by a chuck hand 8 attached to its tip, removed from the movable mold 5, and removed from the product receiving side. taken out.

If a mischuck is caused by the chuck hand 8 when taking out the product, the product 6 will fall into the opening 1a of the machine base 1.

On the other hand, once the product 6 has been taken out, the spray device 9 is guided as shown in FIG. conduct.

At this time, the mold release agent and other spray liquid 10 and burrs 11 fall into the opening 1a of the machine base 1 and are taken out from the passage 1b leading to the opening 1a.

[Problem that the invention attempts to solve]

However, due to a mistake, Machine Base 1
The products 6 that have fallen into the opening 1a are usually not taken out until a plurality of products have accumulated, and after being taken out, they are redissolved and used.

However, after the product is taken out, as shown in Fig. 3, spraying work is performed, so the spray liquid 10 gets hard on the fallen product 6, and it is difficult to re-dissolve the fallen and damaged product 6. However, the spray liquid was mixed in, and the spray liquid could not be reused unless the spray liquid was removed.

In order to avoid this, when a mischuck occurs and the products 6 fall, even if you try to take out the products 6 that have fallen one by one, the bottom of the opening 1a of the machine base 1 will already have spray liquid etc. Product 6 is still contaminated with the spray solution and is unusable even if it is redissolved. In addition, the opening 1a of the machine base 1 is quite deep, making it extremely troublesome to take out fallen products, and moreover, it is extremely dangerous since the work must be done between molds.

Further, the mold release agent in the spray liquid is recovered and reused, but if it contains burrs 11 at this time, it causes clogging of the recovery line, making recovery work extremely troublesome.

[Means for solving problems]

In the present invention, in order to solve the above-mentioned problems, a pedestal that can move back and forth between the side of the molding machine and the bottom of the mold is provided, and the pedestal is guided below the mold when the mold is opened. It is arranged at an angle and has a structure that allows spray liquid, burrs, etc. to be guided out of the molding machine.

In the present invention, more specifically, in a mount device for a molding machine having a fixed platen to which a fixed mold is attached and a movable platen to which a movable die is attached, the lower surface of both molds and the upper surface of the machine base are A stand is installed between the molding machine so that it can be taken in and out from the side of the molding machine, and a protrusion is provided on the bottom surface of the stand, consisting of a thin part at the tip side and a thick part including the slope at the base. A guide roller is installed on the fixed base to guide the pedestal, and when the thick part of the ridge is on the guide roller, the pedestal tilts above the machine base and the side of the molding machine On the other hand, the pedestal was installed in a horizontal position.

[Effect]

When the above-mentioned structure is adopted, the pedestal is located on the side of the molding machine except during the spraying operation, serves as a scaffold, does not interfere with the operation, and is guided between the molds during the spraying operation, allowing the spray liquid to flow The product can be guided out of the molding machine by catching any burrs or burrs, and the spray liquid will not be splashed onto the product that falls due to mischuck.

Furthermore, during molding operations, it is moved back and positioned to the side of the molding machine, so it does not interfere with the molding operations and can also be used as a workbench.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 illustrates one embodiment of the present invention.
In the figures, the same or corresponding parts as in FIGS. 2 and 3 are denoted by the same reference numerals, and the explanation thereof will be omitted.

In this embodiment, a pedestal 12 is provided between the lower surface of the molds 4 and 5 and the upper surface of the machine base 1, so that it can be taken in and out from the side of the molding machine. The pedestal 12 is provided so as to be in a somewhat inclined state below the mold, and to be in a horizontal state on the side of the molding machine.

The width and length of the frame 12 are such that it can fit under the fixed mold 4 and the movable mold 5 between the fixed plate 2 and the movable plate 3 and receive the spray liquid 10 and burrs 11 when the mold is opened. It is about the same size.

The rear end of this frame 12 is connected to the rod 1 of the cylinder 13.
It is rotatably connected to the tip of 3a via a pin 14.

In addition, a protrusion 15 for a guide is provided on the lower surface of the pedestal 12.
is formed along the entire length in the longitudinal direction.

The tip side of this protrusion 15 is thin, and the pedestal 12
The base is a thick portion 15a including a sloped portion.

This protrusion 15 is always in contact with a guide roller 16 mounted on the machine base 1 at a position where it does not interfere with the molding operation. This guide roller 16 guides the pedestal 12 with the protrusion 15 placed thereon.

A discharge port 12a for spray liquid, burrs, etc. is provided at the base of the pedestal 12, and a recovery port 17 for a recovery device for spray liquid, burrs, etc. is provided on the side surface of the machine base 1 on the cylinder 13 side.

When the mold is opened, the pedestal 12 is connected to the fixed platen 2.
When the paper is guided between the movable platen 3 and the movable platen 3, the discharge port 12a at the base of the pedestal 12 is positioned above the collection port 17.

On the other hand, a scraper 18 is provided so as to be movable up and down, and when the pedestal 12 is retreated, it descends and comes into contact with the top surface of the pedestal 12 to scrape the spray liquid, burrs, etc. remaining on the pedestal 12 to the collection port 17 side. It plays the role of evacuation.

Note that when the pedestal 12 is retracted to the side of the molding machine, the pedestal 12 serves as a workbench, so
At this time, the pedestal 12 is placed on a sturdy stand.

Next, the operation of this embodiment configured as above will be explained.

During the molding operation, the cylinder 13 is activated, the rod 13a is moved backward, and the pedestal 12 is pulled out to the side of the molding machine and placed horizontally, serving as a platform for the worker.

At this time, the lower surface of the tip of the pedestal 12 is in contact with the guide roller 16.

On the other hand, the mold is opened and the product is taken out with the pedestal 12 on the side of the molding machine. At this time, if a mischuck occurs, the product 6 will fall to the clean bottom of the machine base 1. When the product removal is completed and the spraying operation is about to start, the cylinder 13
is activated, and the rod 13a moves forward.

As a result, the pedestal 12 is pushed out between the fixed platen 2 and the movable platen 3.

At this time, the protrusion 15 on the lower surface of the pedestal 12 moves in contact with the guide roller 16, so that the thick portion 15a including the slope portion eventually rides on the guide roller 16, and the tip of the pedestal 12 is pushed up, as shown in FIG. As shown in , it tilts and stops with the base side lowered.

In this state, the spray device 9 descends, and the molds 4, 5
is sprayed.

Spray liquid 10 spouted out by this spraying operation
The spray liquid 10 falls on the pedestal 12 together with the burrs 11, and the spray liquid 10 flows on the inclined pedestal 12 together with the burrs 11, and is led from the discharge port 12a to the collection port 17 and collected.

When the spraying work is finished, the cylinder 13 is activated,
Since the rod 13a retreats, the pedestal 12 is pulled back and returns to its original horizontal state.

In this way, the spray liquid and burrs will not fall into the opening 1a side of the machine base 1.
The product 6 that falls due to the mischuck is not splashed with spray liquid.

Therefore, there is no need for post-processing of the products 6, and they can be reused as they are, and the products 6 that have fallen due to the mischuck can be pulled out from the passage 1b every time a predetermined number of products have accumulated.

In addition, in the above-mentioned embodiment, a structure was adopted in which the pedestal 12 is pushed out before the spraying operation is performed, but if the pedestal 12 is pushed out before the product removal device is guided, the product will not fall. The frame 12 can also be used for prevention purposes. At this time, the pedestal 12 is moved backward during spraying.

Furthermore, the above-described device is particularly effective in protecting the casting device when applied to a horizontal clamping vertical casting mold forming device with the casting spout at the bottom.

〔effect〕

As is clear from the above explanation, according to the present invention, when the mold is opened, the platen is arranged in an inclined state between the fixed platen and the movable platen, and when molding is arranged, it is placed in a horizontal state on the side of the molding machine. Since the structure is equipped with a built-in stand, it is possible to prevent spray liquid and burrs from falling onto the product due to mischuck, and it can also be used to prevent products from falling and as a means of protecting the casting equipment. can be used.

In the present invention, a pedestal is provided between the bottom surface of both the fixed mold and the movable mold and the top surface of the machine base, so that it can be taken in and out from the side of the molding machine, and the tip is attached to the bottom surface of the pedestal. A protrusion consisting of a thin part on the side and a thick part including a slope at the base is provided, and a guide roller is provided on the fixed base to guide the pedestal by placing the protrusion on it, and the protrusion and the guide roller are as follows:
When the thick part of the protrusion is on the guide roller, the pedestal is tilted above the machine base, and on the side of the molding machine, the pedestal is in a horizontal state. Therefore, when spraying, the pedestal is placed above the machine base. This not only prevents spray liquid and burrs from falling to the bottom of the machine base, but also prevents them from collecting on the bottom edge of the mount, making it easier to collect them. When removing products from the mold, the stand is moved back to the side of the machine, so that even if the product ejector fails to grasp a product, it will fall to a place below the machine base that is not contaminated with spray liquid. In this case, of course, the product can be prevented from becoming contaminated with spray liquid, and when repairing or inspecting molds, etc., the stand can be removed from the machine. It is extremely convenient because it can be pulled out horizontally to the side and used as a scaffold for workers to stand on.

In addition, in this invention, if a discharge port for spray liquid and burrs, etc. is provided at the base of the pedestal, and a collection port for a recovery device for spray liquid, burrs, etc. is provided on the side of the machine base, spray liquid, burrs, etc. can be removed. can be collected and accumulated reliably and easily.
