本考案はシエル鋳型を造型するためのダンプボ
ツクス式造型装置に関するものである。[Detailed Description of the Invention] The present invention relates to a dump box type molding device for molding a shell mold.

に回動自在に取付けられている。 In general, dump box type molding equipment was developed in 1973.
As shown in Publication No. 86413, this is a device for making a shell mold by dropping sand mixed with resin onto a preheated pattern and hardening the sand with resin, thereby making a shell mold. , and will be explained as shown in FIGS. 1a to 1c. In the figure,
Reference numeral 1 denotes a dump box, which has a rectangular parallelepiped shape, and has a pattern-side opening 1b formed at the lower end of the side wall 1a as shown in the figure, and a partition plate at the upper part of the side wall 1a to divide it into upper and lower parts. 1c is attached so as to be rotatable left and right in the figure.

ある。 Further, the pattern-side opening 1b of the dump box 1 includes a workpiece forming portion 2b and a sprue forming portion 2c formed on the base plate 2a of the pattern 2.
is inserted, the workpiece molding section 2b has the same shape as the outer shape of the workpiece to be cast divided in half, and the sprue molding section 2c is placed on the base plate 2a following the workpiece molding section 2b. The sprue molding part 2c
A flange 2d is integrally formed on the outer end of the shell mold 4.
This is for forming the sprue end face 4b of a to be flat.

開口部1bに着脱自在に取付けられている。 A restriction plate 3 is interposed between the pattern side opening 1b of the dump box 1 and the upper surface of the base plate 2a, and this is connected to the inner surface of the side wall 1a of the dump box 1 and the workpiece forming portion 2b. Alternatively, the restriction plate 3 is used to cover the upper surface of the base plate 2a between the side surface 2e of the flange 2d and make the outer shape of the shell mold 4 into a desired shape. It is detachably attached to 1b.
そしてこの従来装置において、シエル鋳型4を

てシエル鋳型4が形成される。 In this conventional apparatus, when molding the shell mold 4, the partition plate 1c is closed and resin-containing sand 5 is supplied from the supply port (not shown) on the top surface of the dump box 1, and in this state, the dump box is 1 onto the preheated pattern 2, and open the partition plate 1b. Then, the sand 5 falls onto the pattern 2, and is hardened by the resin along the surface shapes of the workpiece molding part 2b and sprue molding part 2c, thereby forming the shell mold 4.
しかしながらこのような従来装置においては、

なつて製造工数が増え、また砂が無駄に消費され
てシエル鋳型の製造コストが高くなるという問題
があつた。 However, in such conventional devices,
Sand also adheres to and hardens on the circumferential surface of the flange 2d of the sprue molding 2c, and sand enters the gap between the side surface 2e of the flange 2d and the side wall 1a of the dump box 1, solidifies, and forms the burr 4c. As shown in Figure 3, the above-mentioned flange 2 is installed to cover the cap to prevent the back-up shot from entering the sprue in the subsequent process.
d It is necessary to remove the sand and burrs 4c on the circumferential surface, which increases the number of manufacturing steps, and the sand is wasted, resulting in an increase in the manufacturing cost of the shell mold.
本考案は、かかる従来の問題点に鑑みてなされ

ものである。 The present invention has been made in view of such conventional problems, and when the dump box and the pattern are combined, the flange has an inner circumferential surface that comes into close contact with the entire circumferential surface of the flange of the pattern. By installing a cover on the restricting plate that covers the entire circumference of the dump box, it is possible to reduce the manufacturing cost and sand consumption without sacrificing the versatility of the dump box, thereby reducing the cost of the shell mold. The aim is to provide the equipment.
以下本考案の実施例を図について説明する。 Embodiments of the present invention will be described below with reference to the drawings.

dの周面を覆うようになつている。 Figures 2a, b and 3 show an embodiment of the present invention. In the figure, the same reference numerals as in FIG. 1 indicate the same or equivalent parts, and a cover 6 is fixed to the vicinity of the end face of the sprue molding part 2c of the restriction plate 3, and the cover 6 is attached to the front semicircular side wall part. 6a and a peripheral wall part 6b integrally formed on the peripheral edge of the cover 6. When the dump box 1 and pattern 2 are combined, the peripheral wall part 6b matches the flange part 2 of pattern 2.
It is designed to cover the circumferential surface of d.

て固まるということはない。 When molding the shell mold 4 using the apparatus of this embodiment, when the partition plate 1c is closed and the sand 5 is supplied, and this is fitted onto the preheated pattern 2, the peripheral wall 6b of the cover 6 forms the pattern 2. This will cover the circumferential surface of the flange 2d, and in this state the partition plate 1c
It is better to open it and let the sand 5 fall. Then, the sand 5 hardens along the surface shapes of the workpiece molding part 2b and sprue molding part 2c of the pattern 2. In this case, since there is a cover 6, the sand 5 is placed on the circumferential surface of the flange 2d or on the side surface 2e of the flange 2d.
There is no possibility that it will get stuck between the dump box 1 and the side wall 1a of the dump box 1.

なうことはない。 In this way, in the device of this embodiment, since the cover 6 is provided to cover the circumferential surface of the flange 2d, burrs are not formed on the sprue end face 4b, and therefore it is naturally unnecessary to remove the burrs, as shown in FIG. Thus, the cap 7 can be inserted as is, and the amount of sand consumed can be reduced. In addition, in this embodiment, the cover 6 is provided on the control board 3, so if a pattern with a different shape is used, the restriction plate and cover can be replaced accordingly, without impairing the versatility of the dump box 1. do not have.
なお、上記実施例では、いわゆる垂直落下式に

を図れる効果がある。 As described above, according to the dump box type molding apparatus according to the present invention, the inner circumference that is in close contact with the entire circumferential surface of the flange at the end of the sprue molding part of the pattern is attached to the restriction plate attached to the pattern side opening of the dump box. Since a cover is provided that has a flat surface and covers the entire circumference of the flange, it is possible to reduce the number of man-hours for manufacturing the shell mold and the amount of sand consumed, thereby reducing costs, without sacrificing the versatility of the dump box. be.
