	Wordwizard Clubhouse - cope & drag
		COPE dates back to the 13th century when it meant cloak or cape and by the 15th century it meant a coffin, a covering of a vaulted form, or a vault.
		The word ‘cope’ was borrowed from medieval Latin ‘capa,’ cloak, from a variant of Late Latin ‘cappa,’ hood, mantle, which produced the English ‘cap.’ So the foundry ‘cope’ can be thought of as the cap or cover of the two piece apparatus.
		DRAG is the bottom half of the ‘flask’ and was so-named in the 19th century.

	Semiconductor device, lead frame and method for manufacturing semiconductor devices - Patent 5493151
		Since the plastic molding is effected with the inner leads disposed between the cope and drag of the mold, a space corresponding to the thickness of the leads is provided between the cope and drag and the resin may flow out from the space in some cases.
		The cavity portions of the cope and drag constructing the mold forming mold and portions near the cavity portions are made in a flat plate form and no concave portions are formed in the facing surfaces of the mold forming mold.
		When the mold forming mold is used and the drag 11 is set in close contact with the cope 12, a portion of the lead frame to be held is fixed between the drag and the cope with a constant force.

		The sand is then struck level with the top edge of the cope, using a wooden or metal strake.
		A board is then placed on top of the drag and the drag is flipped over.

	The Ductile Iron News
		During molding, the cope frame is filled with green sand and the squeeze cycle compresses the green sand, forming the pouring cup, sprue and reverse-taper direct pour unit cavity.
		Attached to the cope pattern was the riser bob required to form the cavity for closing over the direct pouring unit.
		The drag pattern was modified to create a riser basin and a print into which the reverse-taper direct pour unit could be set at the same time the cores were being set.

		Once the drag was completely filled with sand and rammed, we leveled the excess sand off the drag using a strike-off bar.
		Finally, we separated the cope and drag then cut in runners and ingates to connect the spruce and riser holes to the actual pattern.
		The cope was then again placed on the drag and ready to contain the molten metal.

	EMI Top Clamp Series (Site not responding. Last check: 2007-10-24)
		The TC process helps eliminate parting line flashing that is common to cope and drag separation during the machine cycle.
		This is achieved by combining a pair of cope cylinders acting against the drag table cylinder to assure a positive clamping force throughout the described cycles.
		The clamp system is external to the tooling, which allows the cope to move independently of the drag, yielding the opportunity for an effective tamping or cope eject feature.

		The table is lowered and the drag is pushed onto the holding conveyor located on the carousel.
		When the first cope and drag set are stripped, they are pulled out together and sent to the mold prep and closing area, this frees the hold zone for the next drag of this pattern.

	Sand Casting: Introduction
		The drag is first filled partially with sand, and the core print, the cores, and the gating system are placed near the parting line.
		The cope is then assembled to the drag, and the sand is poured on the cope half, covering the pattern, core and the gating system.
		Next, the cope is removed from the drag, and the pattern is carefully removed.

		Plywood tapered tongues on either side provide positive capture and placement of the cope on the drag, retaining the alignment of sand cores between top and bottom.
		By offsetting these tapered tongues, I can ensure that the cope and drag will not inadvertently be rotated with respect to each other.
		I'm also a believer in using drawer pulls on both the cope and drag, so that you have something good and solid to hang onto, when you're trying to lift the cope off prior to rapping the pattern loose.

		The upper or topmost section of the flask of the mold (flask) is called the cope, while the bottom of the mold (flask) is called the drag.
		The operator can adjust to different cope, drag heights and total squeeze pressure to accommodate different mold densities and mold hardness to meet the molding application.

		In 1985, Plant 2, which is the gray iron casting facility, saw the addition of a green sand cope and drag air impulse molding line to serve as the workhorse of its construction casting product line.
		In 1985 when the cope and drag line was installed in the gray iron plant, the molding line was outfitted with the latest PLC technology available at that time.
		In late ’99, the foundry upgraded to the newest PLC controls and networked the molding line to an internal network that had been previously established with the three vertically parted molding lines, the pressure pour furnaces and the sand systems during the re-engineering of Plants 2 and 3 in the late ’80s.

		Not a great pic, but you can see a couple of molding flasks (cope and drag) as well as molding boards, and some ingots.
		Heres how it would go: you set down a bottom board, lightly dust with parting powder, set the drag on top, riddle insome sand, ram it up, riddle in some more greensand, ram, repeat until drag is full.
		When you make your flasks, the cope and drags, be sure to apply a couple of coats of polyurathane finish.
