EJECTOR PINS MUST BE THE 2” SHOULDER TYPE. 2) Use the largest size ejector pin possible. 3) Ejector pins should be cleared to within ¾” of molding surface. 4) Ejector pins should be designed to “PUSH” the part, NOT “PULL” the part. 5) Ejector pin “bosses” can be used only with Customer approval of size and locations. Normally these “bosses” will cause part sink or distortion, therefore use with caution. 6) Ejector pins and Pin Plate must be like- numbered for ease of assembly. 7) All contoured ejector pins must be keyed to prevent rotation by a pocket in the pin plate (refer to drawing S6-1). NO DOWELS WILL BE USED FOR KEYS. 8) All ejector pins must be DME “EX” type or equivalent. 9) There can be no ejection under a slide or lifter detail without written [...]

The vent clearance can be .12” - .50” wide x .02” deep (refer to drawing S5-1) and are always routed to atmosphere. Vents are normally ground. Milled vents must be polished. 2) Perimeter vent land should be .125” minimum to .250” maximum. 3) Always vent directly opposite the gate and at all runner ends/cold well slugs. 4) Ejector pin vents are sometimes necessary. Refer to drawing S5-2 for ejector pin vent design guidelines. 5) Common vent depths (INCHES): ABS-------------------------------------- .001 - .0015 ACETAL-------------------------------- .0005 - .001 ACRYLIC-------------------------------.0015 - .002 CELLULOSE ACET, CAB-----------.001 - .0015 ETHYLENE VINYL ACET.---------.001 - .0015 IONOMER------------------------------.0005 - .001 LCP---------------------------------------.0005 - .0007 NYLON----------------------------------.0003 - .0005 PPO/PPS (NORYL)--------------------.001 - .002 POLYCARBONATE------------------.0015 - .0025 PET, PBT, POLYESTERS------------.0005 - .0007 POLYSULFONE-----------------------.001 - .002 POLYETHYLENE---------------------.0005 - .0012 POLYPROPYLENE-------------------.0005 - .0012 POLYSTYRENE-----------------------.0007 - .0012 HIGH IMPACT POLYSTYRENE---.0008 - .0012 PVC (RIGID)----------------------------.0006 - .001 PVC (FLEXIBLE)----------------------.0005-.0007 POLYURETHANE---------------------.0004 - .0008 SAN---------------------------------------.001 - .0015 T/P ELASTOMER----------------------.0005 - .0007
Injection Mold Cooling System Design
Plastic Injection Mold Cooling System Design Tutorial Section 4:injection mold Cooling Standards and Design Defines methods to provide optimum mold temperature control 1) All molds must be recessed for DME 300 Series Jiffy Quick Disconnects or equivalent Counter bores will be 1.125” diameter to allow for socket. (Refer to drawing S4-1) 2) All mold actions requiring cooling must have ½” I.D. reinforced flexible hoses routed to outside without interference. Jiffy-Tite extension plugs are preferred when possible. 3) In cases where water manifolds are required, CITO type manifolds are preferred. 4) Use DME standard 300 Series male Jiffy-Tite plugs and 300 Series Jiffy-Tite Extension Plugs or equivalent. 5) All baffles are to be DME standard brass plug baffles or equivalent. NO PRESS-FIT BLADES ARE TO BE USED. 6) All pipe plugs are to be brass. Do not use expandable plugs with “o”-rings. 7) All water lines are to be clear of all obstructions. All circuits are to be air checked with 100 lbs. air pressure per square inch. 8) No waterlines are to be less than ¼” from ejector pins or tapped holes. Avoid designing water directly under tapped holes. Water should be spaced no less than 5/8” from molding surfaces where possible. 9) The amount of water and spacing of water [...]
Injection Mold Runner Design
Injection Mold Runner Design Guideline Section 3: Runner System Standards and Design Contents: A) Surface Runner and gate Design Standards B) Hot Runner Design Guidelines C) Three plate runner and Pin-Point gate design Standards A) Surface Runner and gate Design Standards 1) Upmold will NOT specify runner or gate size/configuration without a MOLD FLOW ANALYSIS performed by a reputable source and close documented communication with the Customer. Unless clearly documented on the mold quotation and agreed to by UPmold, the Customer will specify the runner and gate size/configuration and be responsible for part production cycle times. 2) Trapezoidal runners are preferred due to ease of machining and design. Full round runners are acceptable and common, and are necessary with some material types. All runner intersections will have radii added in the direction of flow and have cold slugs at each intersection. Refer to drawing S3-1 for cold runner design guidelines. 3) Edge gate designs are to be the “double chisel” type that can easily be detached from the part. Refer to drawing S3-2 for edge gate design guidelines. 4) Fan gates are commonly used to assist in reducing part warp or to maintain flatness. Refer to drawing S3-3 for fan gate design guidelines. 5) Sub-gate designs vary, and should be addressed on [...]

Any shut-off angle less than three degrees must have written customer approval. 2) Two angle pins will be required on any slide design that exceeds seven inches in length. Consider a center Slide Guide for all long slides. 3) There must be a minimum of three degrees difference between the angle pin and back wedge. 4) The back wedge surface of the slide must have a lamina bronze (preferred) or 0-1 steel wear plate to allow for adjustment and for maintenance of wear surfaces. 5) The back wedge must be designed to resist injection pressure by backing up the entire molding surface. A double-wedge design must be considered for all large molding surfaces. 6) There must be a minimum of 0.20” ( 0.37” preferred ) clearance between slide detail and the molded part when slide is in the back position. 7) There can be no ejection [...]
