Problems solved by technology

Therefore, in the cooling device 10, it is difficult to determine the casting order of the discharged castings, and there is a problem that it is difficult to determine the manufacturing conditions of each casting.
[0016] In addition, in Figure 8 In the cooling device 10 shown, there is a problem that the temperature of the sand rises as a whole due to the long contact time between the casting and the sand in the rotating drum 12
In addition, in Figure 8 In the cooling device 10 shown, there is a problem that there is a lot of human work in the post-processing process.
[0017] According to the technology disclosed in the above-mentioned Patent Document 2, it is possible to prevent the impact marks and cracks of the casting, but there is a problem that the casting cannot be hooked by the hook part due to the position of the lug, and the demoulding cannot be reliably performed.

Embodiment approach 1

[0071] Figure 1A It is a figure which shows an example of the height of the casting mold put into the demolding apparatus of this embodiment, and the casting formed in the casting mold. Figure 1A The mold 102a shown includes an upper mold 103a and a lower mold 104a between which a casting 101a is formed. The casting 101a has a casting 105a and lugs 106a as products. In addition, in Figure 1A In , the case where the maximum height of the upper mold 103a and the lower mold 104a are both 130mm and the height of the mold 102a is 260mm is exemplified. In addition, the upper mold 103a and the lower mold 104a abut against each other at their respective portions having the greatest height, thereby sealing the casting 101a. The protruding portion 107a and the casting portion 108a will be described later.

[0072] Figure 1B It is a figure which shows another example of the height of the casting mold put into the demolding apparatus of this embodiment, and the casting formed in ...

Embodiment approach 2

[0093] In the first embodiment, the angle of the table including the mounting surface of the casting mold is adjusted to adjust the relative position of the lug hook portion and the lug portion of the casting, but the present invention is not limited to Therefore, as described in the description of this embodiment, the table can also be moved up and down.

[0094] Compared with Embodiment 1, this embodiment differs only in the adjustment of the relative position of the lug hook portion and the lug portion of the casting, and the other structures are the same as Embodiment 1. Therefore, reference is made to FIGS. 1 to 4 . instruction of.

[0095] Image 6 yes means Figure 4A A detailed side view of this embodiment of the process shown. Image 6 The shown casting mold 102 is placed on a table 32 , and the height of the movable table 32 can be adjusted by extending and contracting an air cylinder 38 a provided on the back side of the table 32 . The cylinder 38a expands and c...

Embodiment approach 3

[0102] In the first embodiment, the angle of the workbench is adjusted to adjust the relative position of the lug hook part and the lug part of the casting. In the second embodiment, the workbench is moved up and down to Although the relative position of the lug hook part and the lug part of a casting is adjusted, the present invention is not limited thereto, and the lug hook part may be moved as described in the description of this embodiment.

[0103] Compared with Embodiments 1 and 2, this embodiment differs only in the adjustment of the relative position of the lug hook portion and the lug portion of the casting. Other than that, the structure is the same as Embodiment 1. Therefore, reference is made to FIGS. Description of Figure 4.

[0104] Figure 7 yes means Figure 4A A detailed side view of this embodiment of the process shown. Figure 7 The illustrated mold 102 is placed on the table 32 . The position of the ear hook part 31a can be adjusted by extending and con...

Abstract

A method for separating a mold and a device for separating a mold are capable of separating a mold reliably. A casting mold in which a casting having a casting part and a hanger part is formed is separated from the casting. First, based on the position of the hanger part of the casting with reference to the mounting surface of the casting mold, the relative position between the hanger part of thecasting and a hanger hook is adjusted so that the hanger hook can hook the hanger part, and the mounting surface is further rotated by decreasing an angle formed by the mounting surface of the castingmold and the gravity direction, such that while the hanger part of the casting hooks the hanger hook, the casting mode is dropped from the mounting surface.

Description

technical field [0001] The invention relates to a demoulding method and a demoulding device applied to a casting production line. Background technique [0002] In a casting line, after the molten metal poured into the mold solidifies and cools, it is demolded. In the demolding, the casting in which the molten metal has solidified is separated from the already dispersed casting mold, that is, the molding sand. The above-mentioned castings are products, and the above-mentioned molding sand is recovered and reused. As a mold release apparatus which performs mold release, a rotating drum type, a vibrating tank type, and a vibrating drum type can be illustrated. [0003] Patent Document 1, which is an example of prior art, discloses a technique related to mold release using a rotary drum type cooling device. [0004] Figure 8 It is a figure which shows the rotating-drum type cooling apparatus 10 of an example of conventional art. Figure 8 The cooling device 10 shown includes...
