Injection mold inside have what, do you know?

Injection mold is a kind of in the production of plastic products; Is to increase the complete structure of plastic products and precise size of the tool. The structure of injection mold and plastic mold processing quality directly affects the product quality and production efficiency. Injection mold assembly is important in the process of plastic injection mould manufacturing process, closely linked to the quality of die and mould assembly, mold parts by milling, drilling, grinding, CNC, EDM, car, such as machining, after inspection, on assembly process; Assembly quality directly affect the quality of mould, is one of the most important determinants of the quality of the mould; Without high quality mould parts, there is no high quality mould; Only high quality molded parts and the high quality mold assembly process technology, have a high quality of injection mold.



1, assembling mold components

1. , component assembly benchmark are selected according to the small bowl injection mold assembly drawing, select fixed template as a fixed mould component assembly benchmark.


2. Assembly guide bush, will guide suit concentration template guide sleeve hole, when installation, must guarantee the guide bush with fixed template vertical parting surface.


3.
small core assembly, the small core into fixed template small core hole, and guarantee the accuracy of the profile to cooperate. After completion of assembly, placing fixed template on surface grinding machine, with fixed template as a benchmark, parting surface grinding template on the surface, guide sleeve, the upper surface, small core top surface level.


4. Mold base plate assembly, classify on the surface of the plate assembly in the template, and pay attention to check needs to fit between the two plate surface without shaking.


5. Assembly sprue bushing, adjust the fixed mould plate and sprue bushing hole in the center of the fixed template matching position, will match into the sprue bushing, and ensure the sprue bushing bottom fixed template parting surface and the surface level.


6. Assembly set mold base plate fastening screw, adjust fixed mold base plate with fixed template screw hole position, and screwing in the screw, tighten the screw in the form of symmetry.


7. Assembly gate washer, make gate gasket inner hole and sprue bushing outer ring to cooperate with each other, at the same time make the gate washer outer ring and the fixed mould plate gate mat with hole to cooperate with each other.


8. Assembly gate washer tighten screw, adjust the gate washer with fixed mold base plate screw hole position, and screwing screws, tighten the screw in the form of symmetry.


9. Assembly pipe, the pipe joint respectively installed on the fixed template on both sides of the coolant passages, and pay attention to the installation of the seal.



2, assembly dynamic model component

1. , component assembly benchmark are selected according to the small bowl injection mold assembly drawing, wide choices core fixed board as a fixed mould component assembly benchmark.


2. Assembly guide pin, the use of contour block core fixed board pad, use the press to press the guide pillar into guide pin hole, pressure into the guide pillar, the need to ensure that guide pillar center and the core fixed board surface vertically.


3.
large core assembly, the big core into core fixed board core hole, and guarantee the accuracy of the profile to cooperate. After completion of assembly, need to check whether the core fixed board matching surface is flush, if not level, requires the use of surface grinding machine for grinding processing.


4. Assembly core plate, make the core plate relative to the core fixed board qi, assembly, should check whether the joint between the two plate tightly, presence of sloshing phenomenon.


5. Reset lever assembly components


( 1) To push reset pole loading plate, the reset stem bottom shall not be higher than that of push board bottom


( 2) Will pull rod into the ejector plate, pull rod material underside shall not be higher than that of push board bottom


( 3) Stripper plate assembly


( 4) Assembly screws


( 5) The reset lever components into core plate


6. Plate assembly, and pay attention to the installation position and direction of


7. Dynamic model plate assembly, and pay attention to the installation position and direction of


8. Assembly screws, assembling mold base plate fastening screws, tighten the screw in the form of symmetric


9. Garbage pin assembly, according to the requirements of assembly location and assembly rubbish nail


3, clamping


1. Trimming reset lever, check reset lever on the upper surface and the core fixed board surface is flush, if reset lever on the upper surface is higher than core fixed board surface, the king kong file or grinding wheel can be used for finishing.


2. Assembly dynamic template


( 1) Sliding suit into the dynamic template set of holes and guarantee requirements.


( 2) At the center of the sliding sleeve as a benchmark, will move the template component assembly to guide post


3.
clamping, before clamping, should confirm that all the screws are tightened again. Clamping, guide pillar and guide bush should be aligned, the fixed mould components parallel slide, with feeler check the die components and die parting surface contact between components, generally between contact is not greater than zero. 4mm。
