Definitions

  • This invention relates to a horizontally parted molding machine according to the preamble of claim 1.
  • the invention is applicable to various kinds of molding processes such as warm box, hot box, cold box (isocure, S0 2 , C0 2 , methyl formate, etc.) and shell mold process.
  • Horizontally parted molding machines as referred to above are grouped largely into two systems of conventional drag core box lifting system and core box carriage traverse system of carrying out a molding operation by placing a cope core box onto a drag core box.
  • US-A-4 700 767 discloses a moulding machine for molding sand cores employing openable dies and an injection head, comprising a compressed air tank, shutters for feeding air, moveable supports for the head for both horizontal and vertical movement of the latter, a raising piston, a gassing plate, a dowelled plate, and an openable collet.
  • This moulding machine does not permit to solve the problem of the present invention as set out below.
  • the drag core box of a horizontally parted molding machine is usually most heavy among the elements of the machine mechanism, and it requires a great amount of energy to move such a heavy drag core box mechanism. That is, the running cost increases, and these days it is necessary to relieve the impact when a heavy thing is stopped for increasing the machine cycle. Further, these days the size of core boxes is apt to become larger and a working stage is needed for inspecting and cleaning the interior of drag core boxes thereby presenting various problems.
  • the inventor of this invention has made extensively his research and experiment in an attempt to remove the various drawbacks of the known horin- zontally parted molding machines as referred to above, and as a result, he has been successful in developing the horizontally parted molding machine of the present invention.
  • the technical constitution of the invention relates to a horizontally parted, mold molding machine in which a core box consisting of a pair of a cope core box and a drag core box is provided, and blowing, mold ejection and gassing mechanisms are traversably arranged in the above position of said cope core box, characterised in that the drag core box is stationary.
  • the drag core box mechanism is provided with a mechanism of tilting the drag core box by 90 °, and it is also equipped with a mechanism where the gassing mechanism and the blowing mechanism are disengageably connected by a coupling machanism.
  • reference numeral (1) designates a cope core box and numeral (2) a drag core box.
  • the cope core box (1) is disengageably mounted by a known clamping mechanism to the lower end of a guide rod which is driven by a lifting cylinder (3) disposed on an upper frame (18) of the machine frame.
  • Reference (4) designates a blow head carriage and reference (5) a gassing carriage respectively.
  • the carriages (4) and (5) are of the mechanism such that they traverse, by the operation of a traverse cylinder (11), on a rail (7) shown in Fig. 2 and suspended from the lower surface of the upper frame (18).
  • the blow head carriage (4) and the gassing carriage (5) are disengageably connected at their facing side by a coupling mechanism such as a connecting pin (6) as shown in Fig. 1, and when the cope core box (1) rises (together with the gassing carriage) said connecting pin (6) is released from the blow head carriage (4) and only the gassing carriage (5) lifts up.
  • a coupling mechanism such as a connecting pin (6) as shown in Fig. 1, and when the cope core box (1) rises (together with the gassing carriage) said connecting pin (6) is released from the blow head carriage (4) and only the gassing carriage (5) lifts up.
  • Reference (8) is a sand feeding assembly provided between a hopper (19) and the blow head carriage (4).
  • Reference (9) is a blow head, reference (10) a gassing head, reference (12) a known press cylinder provided on a connecting frame (33) of the lifting guide rod, reference (13) a press head of the press cylinder (12), reference (14) a blow tank, reference (15) an ejector cylinder for the cope core box, reference (16) a cylinder for tilting the drag core box by 900, reference (17) a cleaning device of the drag core box, reference (20) a blow plate, reference (21) a blow plate chucking cylinder, reference (22) a cylinder for mounting the cope core box, reference (23) a cleaning device of the blow plate, reference (24) a drag core box chucking cylinder, reference (25) a cylinder used for adjusting a core box removing rail (29) when a core box is replaced, reference (26) a duster tank, reference (27) a frame of the molding machine, and reference (28)
  • Figs. 5 to 14 are schematic views illustrating schematically and partly sectionally the relative positional relationships of the operational sequence at a molding operation by the cope core box, the drag core box, the blow head, the gassing head, etc.
  • Figs. 3 and 5 are front views of the molding machine when the molding operation has been started.
  • the cope core box (1) descends in the state shown in Figs. 3 and 5 as it moves downwardly by means of the lifting cylinder (3) thereby to be clamped onto the drag core box (2).
  • the gassing carriage (5) also descends along with the cope core box (1), when the respective wheels of said gassing carriage are pressed against the rail (7), as shown in Figs. 2 and 6, and simultaneously it is connected to the blow head carriage (4) by means of the connecting pin (6) provided at the gassing carriage (5).
  • the blow head carriage (4) supplied with sand from hopper (19) by the sand feeding assembly (8) is transferred onto the cope core box by the operation of the traverse cylinder (11). At this time, the gassing carriage (5) in a connected state is pushed out to a waiting position.
  • the press head (13) presses the blow head (9) thereby to press the blow plate (20) of said blow head against the upper surface of the cope core box (1).
  • a blow valve (not shown) provided on the upper frame (18) is operated, the compressed air within the blow tank (14) is blown under pressure into the blow head (9) through the press head (13), and the molding sand within the blow head (9) is blown into the molding cavities in the core boxes. Then the air in the blow head is exhausted thereafter releasing the pressing of said blow head (9).
  • the press head (13) presses the gassing head (10) to press the head (10) against the upper surface of said cope core box (1), and a curing gas is injected under pressure by an ordinary method into the molding sand filled in the clamped core box to allow the molding sand to be hardened.
  • a curing gas is injected under pressure by an ordinary method into the molding sand filled in the clamped core box to allow the molding sand to be hardened.
  • a core receiving unloader (31) is inserted beneath the cope core box (1), the moulding (30) carried by the cope core box is released by operating the ejector cylinder (15) provided in the gassing carriage (5), and the moulding (30) is received by the unloader (31) so as to be removed. These are the steps of removal the mouldings in Fig. 12.
  • the drag core box (2) is tilted by 90 ° (Fig. 13), and the cleaning device (17) of said drag core box is operated thereby cleaning said drag core box and spraying a mold release agent or the like thereto.
  • the cope core box (1) is cleaned, when the unloader is retracted, by the cleaning device provided in the unloader.
  • the drag core box (2) is returned by operating the cylinder (16) and transferred to the following molding cycle. This is the return step of the drag core box.
