Mold assembly process
Before the mold assembly process:
1, Should check all the parts of the water, gas, oil hole, and deburring according to the picture size. Blow clean (especially the oil hole), install the plug, plug, check the thimble with a thimble. The gap to hand gently push as well.
2. Trial installation of the main inserts. Check with the mold box with, do not fit into. According to the parts of the benchmarks, one-sided or two-sided repair of the main inserts. The slider limit surface in the main inserts, the Lord Insert dimensions can not exceed 0.02 mm.
3. The inclined mandrel with the main insert. The top of the inclined mandrel top shape with the main insert-shaped surface. With a good demolition of the inclined mandrel oiling.
4. According to the figure size check all the small inserts, inserts the needle, with the size of the slider, chamfer deburring was fitted into the main inserts. The size of the gap as a single small 0.01 to 0.015 mm is better. In case of failure to meet the requirements of the processing of the principle of shape. Where the small insert from the front wall with screws.
Mold check
1. Check whether the entire mold frame during handling during the collision caused by the deformation (raised) as the case with the file or stone flattening, blowing, rubbing, blowing the water, gas, oil holes, screw holes thoroughly engaged. Install the seal, the assembly of the move, set the master insert, and then blow again into the template with screws (screw must be slowly tightened diagonally) installed cold water connector, connecting the pressure test, remove the water pipe after confirmation, Connector.
2. Slider wear plate surface should be about 0.05 millimeters remaining to be fitted, fitted with slider, bead, registration slider in place. When the slider head and the main insert sealing material mouth when there is a margin. To see Clear the parts of the process card or communicate with the process to understand. Which parts should be processed, installed slider ramp on the wear-resistant films.
3. Before clamping the slider removed, mounted straight lock. Fine positioning to see whether there are special requirements for the process card. A slender, thin core need to be inserted, the small mold artificial mold. The mold must Erect gently with a small copper hammer mold. A slight feeling immediately separated. Repeat this action until there are other parts in contact with the normal clamping.
4. Small inserts have the margin need to repair the mold when the principle of repair punch. Sub-surface repair the need to repair the die when the principle of repair, all the surface can not be repaired sag, met avoidance when the collision. The margin of less grinding can be polished. The mold is completed after the re-processing of the machine. In short, all parts should still be horizontal and the vertical corner is rounded.
Install the slider again clamping
1, The slider wear angle error should be checked first. To continue after the closure of mold. It can not be wrong to make a wear-resistant sheet that is not parallel, screw stigma above the wear-resistant films can not be a car, grinding Stigma. If the time is tight. The first car, grinding head but afterward must be corrected.
2. Pad larger than the height of the top of the wooden block. But the thimble plate, insert the return lever began to install the thimble. When loaded into the thumb gently push as well. Including the positioning of the thimble. When the touch is very tight should check Thimble fixed plate and move. The template position deviation or moving template to avoid the hole caused by the non-straight. The error within 0.2 mm can be enlarged through the hole to solve. More than should communicate with the design or process can not be forced to knock.
3. The use of pushing the inner needle into the tube from the depth of the hole leads to positioning on the floor. Start grinding thimble, transparent thimble end surface finish should be the same as the dynamic model core finish. The non-transparent finish can be at a lower level.
4. Move the mold on the turning machine and then turn it over. Remove the bottom plate and the thimble plate. Remove the thimble fixing plate together with the thimble. And drill the inner needle mounting hole on the bottom plate of the movable mold (to lead out the positioning).
5. Pull nails, sprue sets, respectively, to compress the screws to confirm the fixed mold floor and gate plate fit. Fitted with water pipe fittings installed lock module, marked with paint day. Use the turning machine to turn upside down, hanging to the prescribed location.
6. Hot runner molds by type respectively. Hot mouth mounting holes. positioning pinhole. Electric shunt mounting hole depth of the size check.
