Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mold suspension for foam molding that is used when lifting a mold used for in-mold foam molding.

[Conventional technology]

Usually, the mold used for in-mold foam molding consists of two parts: a cavity mold and a core mold, and foamed synthetic resin particles are filled into the cavity created when both molds are closed and then heated and molded.

In such a mold, a hanging ring is provided at the top of the cavity mold and core mold, respectively, and when installing it on the molding machine body or moving it for other purposes,
With the molding surfaces of both molds aligned, a wire rope is hung around the hanging ring of both molds, and the wire rope is hung on a hook such as a hoist and lifted.

Usually, the cavity mold is attached to a fixed formwork of the molding machine body, and the core mold is attached to a movable formwork, and raw materials are filled from a feeder provided on the back side of the cavity mold.

In addition to this, the cavity mold is attached with a mold release pin for taking out the molded product, so it is heavier than the original cavity mold.

For this reason, when the device is hoisted using a wire rope, there is a risk that the center of gravity may shift and tilt due to the weight of these components.

Attaching a mold that has been moved in a tilted state to the molding machine body not only makes the work difficult;
This includes the possibility of causing damage to the feeder, release pin, etc.

[Problem that the invention attempts to solve]

In view of the above problems, the present invention is designed to integrally lift a foam molding mold consisting of a cavity mold and a core mold, and to make the lifting center of gravity variable depending on the weight or shape of both molds. The object of the present invention is to provide a mold lifting tool for foam molding that enables vertical lifting of foam molds.

[Means for solving problems]

In order to achieve the above object, the present invention is a foam molding device in which a length adjustment tool is provided on at least one of two mold hanging strips, one end of which is attached to a hanging ring and the other end of which is provided with a hook member. This constitutes a mold hanger.

Here, a turnbuckle can be used as the length adjuster, and a shackle can be used as the hanging ring.

[Effect]

The foam molding mold suspension device according to the present invention has the above-mentioned configuration, and has two hanging rings each provided on the cavity mold and the core mold of the foam molding mold.
Hook members of two mold hanging strips, adjust the length of at least one of the strips using a length adjuster, hook the hanging ring to a hook such as a hoist,
This is to lift the mold vertically.

〔Example〕

The details of the present invention will be explained based on illustrated embodiments.

FIG. 1 is an illustrative front view of an embodiment of a mold hanger for foam molding according to the present invention.

In the figure, reference numeral 1 denotes a hanging ring that is hung on a hook provided on a hoist or the like, and for example, a so-called shackle as shown in the figure can be used.

Reference numerals 2 and 3 designate strips for hanging molds, one end of which is attached to the hanging ring 1, and the other end of which is provided with a hook member 4.

The mold suspension strip 2 has a certain length for lifting the foam molding mold, and the one shown uses a chain 5 having a predetermined length. It is also possible to use a wire rope or the like, and there is no particular limitation.

The mold hanging strip 3 has a length adjustment tool 6 at an appropriate midpoint.
In the illustrated example, a turnbuckle is used as the length adjustment tool 6.

This turnbuckle is made up of two joints 7 and 8, each having a right-hand thread and a left-hand thread, connected by a nut 9, and the length can be adjusted by rotating the nut 9.

Reference numeral 10 denotes a chain that connects the length adjuster 6 and the hook member 4, and a wire rope or the like may also be used.

The hook member 4 is not limited to the one shown, and various types of hooks can be used, but at least one that can hang a hanging ring provided at the top of the foam molding mold. will be used.

In addition, in this embodiment, the mold hanging strips 2, 3
Although only one of the strips 3 is provided with the length adjuster 6, it is also possible to provide a similar length adjuster on the strip 2 as well, and there is no particular limitation.

FIG. 2 is an explanatory diagram showing a state in which the foam molding mold hanger according to the present invention is attached to a mold.

The foam molding mold 11 consists of a core mold 12 and a cavity mold 13, each of which has a hanging ring 1 at the top.
4.15.

A feeder 16 for filling raw materials and a mold release pin 17 for taking out the molded product are attached to the back side of the cavity mold 13.

Further, drain pipes 18 and 19 for discharging heated waste steam, heated condensed water, cooling water, etc. are provided on the lower surfaces of the core mold 12 and the cavity mold 13, respectively.

When lifting the mold 11, in order to prevent the core mold 12 and cavity mold 13 from opening during movement or shifting the molding surface,
2 and the drain pipes 18 and 19 of the cavity mold 13 are fastened with a belt 20.

As the belt 20, a wire, chain, rope, etc. can be used, but it is preferable to use a belt made of cloth with a stopper that can be easily tightened and loosened.

Also, although not necessarily required, core type 1
2. The hanging rings 14 and 15 of the cavity mold 13 may be fastened with a similar belt.

Next, the hook members 4 of the mold hanging strips 2 and 3 are
Hanging rings 14 and 1 of the foam molding mold 11, respectively.
5, and the mold is lifted by hanging the hanging ring 1 on a hook (not shown) such as a hoist.

When the hook member 4 of the strip 3 provided with the length adjuster 6 is attached to the cavity mold, if it is tilted toward the core mold 12, rotate the nut 9 of the length adjuster 6 to lengthen the strip 3. Also, cavity type 13
When leaning to the side, tighten the nut 9 of the length adjuster 6.
is rotated to shorten the strip 3 and adjust the foam mold 11 to be lifted vertically.

In the case of a heavy mold, lower the foam molding mold 11 and adjust the length adjuster 6, lift the mold 11 and check the inclination. The process of lowering and adjusting the foam mold 11 is repeated to adjust the foam mold 11 so that it can be lifted vertically.

Even when the suspension ring 14 of the core mold 12 is attached with a strip provided with a length adjuster,
Similarly, by adjusting the length adjusting tool, the foam mold 11 can be lifted vertically.

In addition, when using a turnbuckle as the length adjustment tool 6, the length position corresponding to the frequently used foam molding mold should be written on the nut 9 with a mark, marker ink, or other writing method. If so, adjustments can be made easily.

The mold suspender for foam molding according to the present invention is constructed as described above, and the length adjuster 6 is adjusted to change the length of the strip 3 according to the weight or shape of the mold 11 to be lifted. This makes it possible to vertically lift the foam mold 11.

This makes it possible to easily attach the mold 11 to the molding machine and to prevent damage to the feeder 16, mold release pin 17, etc.

Since a turnbuckle is used as the length adjuster 6, it is possible to continuously change the length of the mold hanging strip 3, and it can be applied to molds of various shapes and weights. is possible.

[Effect of idea]

The foam molding mold lifting device according to the present invention is constructed as described above, and the length of the strip for lifting the foam molding mold is adjusted by the length adjusting device, thereby changing the position of the center of gravity for lifting. , which allows the foam mold to be lifted vertically.

This makes it easy to attach the foam molding mold to the molding machine body, and also prevents damage to the feeder, mold release pin, etc.
