Battery cover closed injection mold

Pulling on both sides to achieve. Requirements cover the outer surface smooth, can not have a gate and ejector marks. Comprehensive consideration of product requirements of Taiwan decided to adopt after the feed point gate, gate located at the outer surface of the central strip products, the groove, the battery assembly, the required cover sheet sealing tight here, it may cover the gate vestige . From the inner surface of dense ribs, boss, clamp, and a smaller ejection gradient consideration, the mold core part of the design to be carefully analyzed. Due to limited processing equipment, the overall core processing very difficult, so consider designing mosaic-type core addition, the product material is polypropylene, the shrinkage rate is high, with dense ribs, clips. Allowing for the ejection resistance is considerable. Die before the occurrence of such serious white top part of the appearance of a defect, has been unable to eliminate. So stripping agency in the design, the use of push linkage, the force distributed ejector to overcome the top-out the beginning of the deformation, pressure plate side of force, size adjustable, when the die contacts the workpiece. tensile stress began to impose on board, into the die, the combined side wall of the extrusion pressure, increases the radial tensile stress, plastic deformation of the metal produced more fully. makes the cap area of the inner and outer beams are in a stretched metal metal fibers have sufficient elongation, therefore rebound less.

Side Luo at Cardiff, etc. Principles of metal pressure processing Machine Press, 1980. block. Otherwise angle pin will not be able to pull pumping action. locking wedge angle calculation method:. c, a + (2. ~ 3. 13.2 synchronized stripping plunger and push the board due to the inner surface of the plastic bar Article dense parts of complex shape and slope requirements of the ejection is small, it is difficult to cause ejection parts. the original mold used for single-top peak of the staff out of parts too large ejection resistance caused serious impact on the top surface of the part of white This design uses top quality,mulberry københavn, push sync stripping. increase over the border of the push plate, spread the push rod of the ejection resistance. to remove the top of the white marks. 3.3 angle pin and slide with the class before the scheduled mode angle pin mold used in the fixed mode, the slider assembly fitter reflected in the dynamic model with repair problems, resulting in core parts of the slider and the cavity mold plastic parts large gap Pulling significant parts of the dislocation traces are used affect the appearance angle pin, the slider with the given model. easy to slide with core and cavity repair and assembly,mulberry outlet, to ensure that the gap is small and easy-to-face with the control. more than 3.4 cavity insert block to the complex shape plastic parts Die molding process caused great difficulties in order to simplify the number of inserts used to solve the problem of abnormal processing of the die, Figure 5 shows an insert which inserts into the 8mm hole through a set of core fixed to the inserts in rectangle on the insert into the ring boss 5I. insert 2. insert 3. cylindrical pin 4. die sets i0 × 5ram the tank. In order to avoid the molding process of plastic squeeze into the groove inserts used, the clearance hole must be properly set aside, and with the inserts with repair. As Figure 5 in the rectangular slot for the 10 × 5ram, its depth is 13 a -0 .with poor repair process difficult,mulberry sverige, but the icon structure with a diameter of 12mm with a cylindrical pin into the interference is resolved to make this process difficult. 3.5 modular core As mentioned earlier, mold core part of vertical and horizontal ribs staggered, complex structure, making the mold core forming process is difficult under the condition of existing equipment, designed to mold core mold core is composed of six monomers and small patches of fixed combination of a fixed plate. machining process,mac cosmetics discount, using some of the dimensions critical dimensions forming monomer mix processing. as shown in Figure 6 and the patch edge to patch and 1 ~ 6 punch combination to form the workpiece 28 on the clamp. This combination punch machine, not only in general processing can be completed and size of various parts of the ship is also guaranteed. lap 61. 2,356,7,8 patch edge. 4 core mold used patches effect of 4 sealed battery cover of the injection mold for manufacturing a smooth, completed in full accordance with the implementation of design intent. tooling for the first time on the machine commissioning, will be successful, output high quality products. put upon proof small batch production, the mold structure reasonably safe and reliable operation and low cost mold manufacturing,ed hardy nederland, product quality and size of appearance precision products have reached the top of the white marks drawings completely eliminated. Pulling No part of the integrated use of defects such as flash situation. The mold design is reasonable and reliable, the use of good results.
