Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、複数の型で成形される成形物を脱型するた
めの脱型装置に関する。TECHNICAL FIELD The present invention relates to a demolding device for demolding a molded product molded by a plurality of molds.
従来におけるこの種の成形装置にあっては、型に透孔を
穿つとともにこの透孔に抜型ピンを嵌挿し、この抜型ピ

にしていた。そして、成形後、この抜型ピンによって成
形物を押し出すことにより脱型していた。In a conventional molding apparatus of this type, a through hole is formed in a mold, a die pin is fitted into the through hole, and the tip surface of the die pin is flush with the cavity surface of the inner die (center of the die). I was doing. Then, after molding, the molded product was extruded by extruding the molded product with this punch pin.
しかしながら、かかる従来の装置にあっては、前記透孔

まい、摺動不能となってしまうという不都合も有してい
た。However, in such a conventional apparatus, the through holes are likely to be clogged with hot water, so that it is difficult to improve the efficiency of the demolding work. In addition, since the pressing member is in the inner mold (center part of the mold), the mold temperature becomes high, and as a result, the pressed part (of the cast product) is insufficiently solidified. Not only will it leave marks on the cast product, but it will also cause deformation of the cast product itself, and since the temperature is high, when the press member is installed in the inner mold (center of the mold), the press member itself will be baked. There was also the inconvenience that it caused sliding and could not slide.
この発明は前記不都合を解消するためになされたもので
あり、 その要旨は、 成形物を押圧部材によって押し出すことにより当該型か
ら脱型する脱型装置において、 前記押圧部材を、成形物を成形すべきキャビティの内壁
面とは別体に設置したものである。This invention has been made to solve the above-mentioned inconvenience, and its gist is a demolding device for demolding a molded product from a mold by pushing the molded product with a pressing member. It is installed separately from the inner wall surface of the power cavity.
なお、前記成形物の被押圧部を、脱型すべき型における
成形面の周方向に突設させることもできる。The pressed portion of the molded product may be provided so as to project in the circumferential direction of the molding surface of the mold to be demolded.
この発明に係る脱型装置は上記のように構成されている
ため、脱型すべき型に透孔を設ける必要がないものであ
る。Since the demolding device according to the present invention is configured as described above, it is not necessary to provide a through hole in the mold to be demolded.
なお、前記成形物の被押圧部を、脱型すべき型における
成形面の周方向に突設させれば、押圧部材は脱型すべき
型における成形面の外周に配置することができるもので
ある。If the pressed portion of the molded product is provided so as to project in the circumferential direction of the molding surface of the mold to be demolded, the pressing member can be arranged on the outer periphery of the molding surface of the mold to be demolded. is there.
以下、この発明の実施例として車両用ホイールの鋳造に
おける脱型を採りあげ、第１図に基づいて説明する。Hereinafter, as an embodiment of the present invention, the demolding in the casting of a vehicle wheel will be taken up and explained with reference to FIG.

し、前記横型６によって形成される。In the figure, 1 is a support member, 11 and 11 are support rods projecting downward from the support member 1, and 3 is an upper die fixed to the lower ends of the support rods 11 and 11. The upper mold 3 forms the back surface of a vehicle wheel (corresponding to the "molded product" of the present invention) H. Reference numeral 4 is a base for the lower mold, and 5 is a lower mold fixed to the base 4. The lower mold 5 molds the back surface of the disk portion D of the vehicle wheel H. Reference numeral 51 is a spout formed in the lower mold, and 52 is a stalk connected to the spout 51. Next, 6 is a horizontal type which is a split type, and is slidably fixed to the base 4. The horizontal mold 6 forms the surface of the rim portion R of the vehicle wheel H. Reference numeral 7 denotes a rim flange, which is formed integrally with the end edge of the rim portion R of the vehicle wheel H. The rim flange 7 corresponds to the pressed portion of the present invention and is formed by the horizontal mold 6.

手段である。Reference numeral 8 is a guide plate having through holes 81, 81. The guide plate 8 is fitted onto the support rods 11 and 11 via the through holes 81 and 81 so as to be vertically movable. Reference numerals 82 and 82 denote interlocking rods, which project from the lower surface of the guide plate 8. Further, 9 is an annular pressing member, which is fixed to the lower ends of the interlocking rods 82, 82. Therefore, when the guide plate 8 moves up and down, the annular pressing member 9 also moves up and down. Reference numerals 83 and 83 are passive parts of the guide plate, and 84 and 84 are operating means for moving the guide plate 8 up and down via the passive parts 83 and 83.
このように構成される脱型装置において車両用ホイール

ともできるものである。First, the lateral dies 6, 6 on both sides are moved to the outside to release them from the vehicle wheel (molded product). At this time, the rim flange 7 of the vehicle wheel H projects from the molding surface of the upper mold 3 in the outer peripheral direction (lateral direction). Then, while the vehicle wheel (molded product) H is attached to the upper mold 3, the vehicle wheel
The vehicle wheel (molded product) H is moved by 1.2 meters to be released from the lower mold 5 (because the gate 51 is not solidified, the vehicle wheel (molded product) is torn off). At this time, the actuating means 84 is driven with a slight delay,
The guide plate 8 and thus the annular pushing member 9 are pushed down. Then, as is clear from FIG. 1, the annular push-out member 9 presses the rim flange 7 of the vehicle wheel (molded product) H downward, so that the vehicle wheel (molded product) H is moved upward. Falls off and falls. As a result, the vehicle wheel (molded product) H is released from all the molds 3, 6, 6, 5. The annular pushing member 9 may be fixed and the upper die 3 may be raised to press the rim flange 7 of the vehicle wheel (molded product) H downward.
