Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a product take-out device for taking out a product (cast product) cast using a die-casting machine from its mold.

<Prior art> Conventionally, there have been various types of seed extraction devices of this type, but in all of them, the extraction member for directly taking out the product is fixed to the arm supporting it. Because it is attached, if the ejection member or the product being ejected gets caught in the die-casting machine or mold, it may damage the die-casting machine or the mold or damage the ejection device itself. , which could cause serious accidents.

<Problems to be solved by the invention> The present invention has been made in view of the above-mentioned drawbacks of the conventional technology. To provide a product take-out device for die-casting, which is attached so as to be detached from an arm if it hangs, and which is free from the risk of damaging a die-casting machine or a mold or damaging the take-out device itself.

<Means for solving the problem> The product take-out device for die-casting according to the present invention that achieves the above object has a device at the tip of an arm that reciprocates between the mold of the die-casting machine and the outside of the mold. A support member is fixed at intervals of the thickness of the attachment part of the extraction member, and a locking piece is slidably provided on the support member so that the tip of the locking piece can freely appear between the support parts and can be retracted. The locking piece is characterized in that a pressing medium is provided to urge the locking piece toward its tip side, and the tip of the locking piece is press-locked to the mounting part of the extraction member, and the mounting part is supported in a detachable manner. do.

<Function> According to the above-mentioned technical means of the present invention, the product being taken out gets caught in the die-casting machine, the mold, etc., and a load larger than the pressing locking force of the locking piece is applied to the taking-out member. When this happens, the attachment part of the take-out member comes off the tip of the locking piece, and the take-out member comes off the support member at the end of the arm and falls off together with the product.

<Example> Hereinafter, an example of implementing the present invention will be described based on the drawings.

The arm 1 is for reciprocating the take-out member 2 that directly takes out the product a between the mold B of the die-casting machine A and the outside of the mold B (the captain's side of the die-casting machine A or the side opposite to the captain's side). However, the mechanical structure thereof may be of a conventionally known type. The illustrated embodiment is composed of a main arm 1a and a sub-arm 1b which is made up of a plurality of plate materials attached to the tip of the main arm 1a and extends and contracts in the mold opening direction of the mold B.
By rotating and reciprocating the base end of the arm 1, the ejecting member 2 is reciprocated between the mold B and the outside of the mold B. A support member 1d is attached to the lower end of one support plate 1c of the sub arm 1b that moves in the mold opening direction of mold B.
is fixed to the distal end 1'd of the support member 1d, and the removal member 2 is press-locked by the locking piece 3 and detachably attached (see FIG. 4).

The support member 1d is fixed horizontally to the lower end of the support plate 1c of the sub-arm 1b at a thickness interval of the attachment portion 2a of the extraction member 2, and is attached in a substantially U-shape in plan view.

The extraction member 2 directly transfers the cast product a to the mold B.
It may be a conventionally known chuck type for gripping the biscuit part of product a, or it may be a hook part b formed integrally with product a, as shown in the illustrated embodiment, for suspending and supporting the product. A hook-type one with a handle may also be used.

In the case of a hook type, a hook 9 is provided on the hook 2' of the take-out member 2 so as to be movable up and down with a spring 10, as shown in the example shown in the figure, so that the suspended product a is inadvertently removed from the hook 2'. Make sure it doesn't fall off.

The locking piece 3 is a support member 1d of an arm tip 1'd formed into a substantially U-shaped plane by attaching a support member 1d.
The distal end 3a of the support tube 4 is slidably installed in a support tube 4 fixed to the support member 1d, and its tip 3a is allowed to freely appear in the direction of the mounting portion 2a of the extraction member 2 through a hole 5 drilled in the support member 1d. The portion 3b is biased by a pressing medium installed in the support cylinder 4, and in the illustrated embodiment, a spring 6, and the pressing force of the spring 6 presses and locks the tip portion 3a to the mounting portion 2a of the removal member 2. The mounting portion 2a is removably mounted and supported between the supporting members 1d (see FIG. 3).

In addition, the pressing locking force of the locking piece 3 tip 3a against the mounting portion 2a by the spring 6 will be applied in any case because the weight of the product a varies depending on the size of the product a and the material (aluminum, etc.) from which the product a is made. It is arbitrarily set according to the product a to be taken out so that the product a can be suspended, and in the figure, 7 is an adjustment screw for adjusting the pressing locking force, and 8 is a mounting portion 2a of the removal member 2. This is an engagement recess provided in the mounting portion 2a to ensure a stable and reliable press-locked state of the tip end 3a of the locking piece 3.

Furthermore, only one locking piece 3 may be installed on the support member 1d on both the left and right sides of the arm tip 1'd, or on one of the support members 1d using the support tube 4, but as shown in the example shown in FIG. A total of four locking pieces are installed, two of which are placed in parallel on each side of the locking piece 1d, and the pressing locking force of the front locking piece 3 against the mounting portion 2a of the extraction member 2 is set to be a little weaker than that of the rear locking piece 3. Therefore, when a load exceeding the set pressure locking force of the front locking piece 3 is applied to the ejection member 2, the mounting portion 2a comes off from the front locking piece 3, and the ejection member 2 is locked from the rear. Stop piece 3
The product a tilts as shown in FIG. 1 while being supported only by the hook portion 2' and falls off.
When a further load is applied, the attachment portion 2a also comes off from the rear locking piece 3, and the extraction member 2 completely falls off from the arm tip 1'd.

Therefore, the extraction members 2 should be installed on the arm tip 1'd like this in parallel in the front and back, and the pressing locking force of the front locking piece 3 should be set to be weak for mounting and support. Therefore, if only the product a gets caught in the die-casting machine, mold, etc. during taking out, only the product a will come off the hook part 2' of the taking out member 2 and fall off, and the taking out member 2 will fall off the arm tip 1. 'd remains;
If the product a does not come off the hook part 2' even if the take-out member 2 is tilted, or if the take-out member 2 gets caught in a die-casting machine, a mold, etc., the take-out member 2 is also attached to the product a. take off.

It should be easily understood that the take-out device of the present invention can be applied not only to die-cast products, but also to take-out of products molded using an injection molding machine, such as molded products in mold casting and resin molding. be.

<Effects of the Invention> Since the product take-out device of the present invention is constructed as described above, it exhibits the following effects.

During extraction, if the extraction member or product gets caught in the die-casting machine, mold, etc. and a load greater than the set value is applied to the extrusion member, which is greater than the pressing locking force of the locking piece, the mounting part will come off from the locking piece. The extrusion member falls off from the tip of the arm together with the product.

Therefore, it is possible to reliably prevent damage to the die-casting machine, mold, etc. or damage to the take-out device itself due to the take-out member or the product being caught.

Thus, the intended purpose can be achieved.
