AMTS07 Mold Construction 7-01AMTS 7.0 Mold Construction 7.1 All molds are to have the following items included in the design and construction of the mold. Argo Mold will list design guidelines to follow, for help in explanations. 7.2 All molds must have two (2) CRS safety straps permanently mounted to their sides to prevent the mold from opening while being handled. In molds being built for 1500 tons and up, 4 safety straps will be used. 7.2.1 The thickness of the straps will be compatible with the mold weight. 7.2.2 The width of the straps will be a minimum of three diameters of the clearance holes drilled to receive the two bolts that will hold the strap in place. 7.2.3 Standard socket head cap screws will permanently affix the straps to the stationary half of the mold. The socket head cap screws will be sized according to the mold weight. 7.2.4 A hole in the moveable half of the mold will be drilled and tapped to accept the socket head cap screw that will hold the safety strap in position. A similar hole will be drilled on the stationary half to allow the strap to rotate and be attached to the stationary half when the mold is in use. 7.3 All molds are to have the following identification clearly stamped on the mold. Stamping is to be a minimum of .005” deep and large enough to be readable. 7.3.1 The mold must be stamped “Top” on the top of the mold. 7.3.2 All mold plates will be numbered in numerical order as defined by the mold drawings. 7.3.3 A mold plaque will be constructed and mounted on the operator side of the mold. The plaques will be screwed into a pocket that recesses the plaque at least 1/16th of an inch from the outer surface. Each plaque is to include at least the following information: 7.3.3.1 Part name 7.3.3.2 Part number 7.3.3.3 Tool I.D. number 7.3.3.4 Customer name 7.3.3.5 Number of cavities 7.3.3.6 Weights of each half (lbs. or kg.) 7.3.3.7 Total mold weight (lbs. or kg.) 7.3.3.8 Length of ejector stroke (inches or millimeters) 7.3.3.9 Applicable core sequence (as defined below) 7.3.3.10 Tool manufacturer 7.3.3.11 Tool manufacturer’s I.D. number 7.3.4 Each sketch rendered will be modified to show the hookups of the utilities to each circuit corresponding to the identification scheme. The modified sketches will then be rendered as a plaque mounted into a recessed pocket on the mold. Positioned to be easily readable to help in installing the utilities during the mold set up procedure. 7.4 The following design guide lines should be followed when designing water lines into Argo Mold molds: 7.4.1 Water lines must be added to design at same time as ejection. Sometimes water lines are moved in favor of ejection, and vice-versa. 7.4.2 Is mold cooling analysis required? If so, a drawing or cad file will have to be sent to sources after waterlines are on design. 7.4.3 All drilled holes must be labeled and dimensioned in plan views, sections, and views, as per Argo Mold standards. 7.4.4 There must be enough sections and views to clearly show all waterlines. 7.4.5 Cover and ejector plan views should have shaded arrows on center lines showing the direction of the flow. 7.4.6 Do inlets and outlets clear all other details? (Including clamp holes, large diameter of shoulder on hoist rings, etc.?). 7.4.7 Cover and ejector plan views require chart showing baffle depths. 7.4.8 Are proper hoses and fittings shown as per Argo Mold specs? 7.4.9 Thermal pins are used for hard to cool areas. 7.4.10 Do not use “O” rings unless approved by Argo Mold. 7.4.11 Female water fittings on ends of buried pipes should be silver soldered to pipe. 7.4.12 Waterline schematic drawing is required for cover and ejector that can be used to make photo-etched aluminum plaque. The size of the plaque is to be determined by the available space on the operator side. “Top of mold” and “Operator Side” must be on the drawing. 7.5 Each hydraulic circuit is to be identified on the mold surface or an accompanying I.D. plaque identifying its purpose, such as “Core 1" or “Core 2". It’s forward and return positions will be identified with an “F” or “R” respectively. The identification is to include notation for the side that is pressurized and the maximum operating pressure. 7.6 Each compressed air circuit is to be identified on the mold surface identifying its purpose, such as “Poppet” or “Blow Off.” Each circuit is to be fitted with a quick disconnect and labeled “Air in.” 7.7 The mold will be painted per the following specifications: 7.7.1 The ejector box will be painted bright orange to comply with OSHA Standards. 7.7.2 The safety straps will be painted bright yellow. 7.7.3 All moving components on the outside surface of the mold will be painted bright orange to comply with OSHA Standards. 7.8 Whenever possible, all components, (bolts, heaters, thermocouples, hydraulic cylinders, etc.) are to be standard models and readily available from a number of sources. Similar components should be used whenever possible to avoid an extensive part list and provide for a minimum amount of inventory. Custom components should be avoided and must be approved prior to use. Argo Mold standard component requirements should be followed as close as possible. 7.9 Each mold will have sufficient handling holes drilled and tapped. They will be to the table noted in Section 1.H.3 to allow handling each half of the mold and each individual mold plate. The locations of these holes are to be placed with respect to the balance point of the plates or mold halves. 7.9.1 Each mold will have holes drilled and tapped to a sufficient depth to accept Safety Hoist Rings.
