As the product of the material is PVC, look-up table obtained: the injection molding pressure required to get 80 ~ 100MPa; XSZ60 the largest injection molding machine turn force 122MPa; Therefore, the maximum injection pressure injection machine can meet the design requirements . 4-3.3 clamping force clamping force of the check, also known as clamping force injection molding machine is the mold clamping device can exert maximum clamping force. Cavity pressure to open the top trends in the mold for injection molding process to ensure that mold will not have excess material to be the top open, clamping force must be greater than the cavity pressure and melt type casting system and the projected area of ​​the surface of the product , that satisfy the formula (5): Fo ≥ F = PA points × 100% (5) where F_ injection machine clamping force for said (N); P - mold mean pressure (average melt cavity Pressure MPa), take 24.5MPa; A - plastic parts, flow, gate type plane in the projection area of ​​the * ll (cvn3), F - injection pressure in the force produced by the cavity ( N). Known = 500MPa (XSZ60 clamping force injection molding machine), based on experience to take P # = 24.5MPa, using Pro / E analysis of the A} 23.3cm. Then F = 57085N, meet the design requirements. 4.3.4 check opening stroke of the opening stroke of plastic injection molding machine is limited, opening stroke should be separated from the mold out to meet the needs of plastic parts. Therefore, the injection molding machine's opening stroke must be greater than required to remove the plastic parts from the mold. The design of the selected injection machine XSZ ~ 60 and the maximum opening stroke size of the structure by a connecting rod (or move the cylinder) the maximum stroke the decision has nothing to do with the mold thickness. For a single sub-surface mold, the mold {left foot range by the formula (6) Check: S ≥ H + H, + (5 ~ 10) (6) where S - the largest opening stroke injection molding machine (moving template travel ) (ram); H - Core height (ram); H, - including plastic parts, including pouring system height (ram). Using Pro / E analysis are: H + H, + (5 ~ 10) - 40} 126 +5 = 17lmm76 die 1 = process MOULD & DIEPROJECT2009 ~ V 9 (Total 101 Thus, by the above calculation and verification , NCfll80mm (XS-Z an open mold injection molding machine 60 trips) from the open mode to meet the design requirements. 5 tee mold assembly diagram BU Ding mold base plate; 2 a guide sleeve; 3,gorras ed hardy, a locking screw; 4 - angle pin ; 5 for a plastic parts; 6 - core; 7, a positioning ring; 8, a gate set; 9, a cooling water; lo-4 ~ 4 core; 11_ locking block; 12, certain template; 13 - fixed template; 14 - plate; 15 - putting the fixed plate; 16, a push plate; 17, a fixed screw: A limit of 18 nails; a fixed mold base plate 19; 20 locking screw; 21 - Pad; 22, a push tube: a push rod 23: 24 ~ 12 pillar ring mold assembly Figure 6 summarizes this point, the three-way pipe mold design work is completed. Now the process of design problems interrupted, the corresponding solutions, and tips, etc. are summarized as follows: (1) during the design of the side core pulling, side core encountered the phenomenon can not be successfully extracted, and finally rewrite the part of the structure, complete the stripping process of plastic parts. (2) institutions during the launch of the design of plastic parts,ed hardy günstig, taking into account the three structural factors through a special tube, select a combination of push tube and push the program, which makes the introduction of uniform and stable power to avoid the plastic parts to generate additional stress. (3) In carrying out the cooling system design, full use of MPI software cool channel optimization,ed hardy mexico, and ultimately get a reasonable solution to shorten the plastic molding cycle,mulberry laukku, reduce production costs. tooling design is a fairly comprehensive ability of technology, the design will meet some of the many technical problems of theoretical knowledge alone is completely inadequate ,ed hardy suomessa, which requires designers from various access to information, learn from previous experience in the practice and theory as a guide.
