How to carry out injection design audit?
(1) general review of mold design
Whether to consider the plastic raw material process characteristics, molding performance and injection molding machine on the quality of molding.
Whether some specific measures have been taken in the design of substances regarding possible defects in the process of forming.
Whether the structural dimension design of molding parts is correct, and whether the required dimension precision of injection molding products can be guaranteed.
Whether to take into account the requirements of injection molding products for mold guidance precision, and whether the structure design of guide mechanism is reasonable.
Flow forming parts and supporting parts are of sufficient strength and stiffness to ensure mold forming quality.
6 mold in the process of assembly and use, often need to adjust ^ and mold finishing, so in the design of the mould, mould test and repair the mold requirements should be considered.
The installation and removal of the tool is often encountered, so it is necessary to take into account the pry groove, hole and traction screw used in the installation and removal of the tool, and make a clear mark.
Shorter molds need to be moved frequently, and for ease of handling, consider rings or rings for handling
Lifting screw hole and marking.
(2) mold structure audit
The structure and basic parameters of the die must match the specifications of the injection molding machine to be installed.
Whether the fractal surface selection of parliamentary mould is reasonable, whether it is possible to produce flying edges, and whether the products can be reliably extruded.
Whether the structural design of molding parts is reasonable, whether the structure is simple, whether the processing is easy, and whether the assembly is convenient.
Whether the pouring system design is reasonable, whether the position of gate is suitable, whether the gate is suitable for plastic material, and whether the geometry and size of gate and runner are suitable.
If the ejection mechanism and side parting or core pulling mechanism are reasonably designed, safely and reliably.
Is there any need for a temperature control system, and if so, is it reasonable to design a circulating circuit for the heating and cooling medium?
If the exhaust mechanism needs to be set up, check whether it is reasonable.
Whether the appearance size of chrysanthemum mould affects installation, and whether the choice of fastening mode is reasonable and reliable.
(3) mold design drawing audit
Review the assembly drawing, pay attention to whether the parts are clearly related to the assembly, and cooperate with the code
Whether it is accurate, whether the part standard is complete, whether it corresponds with the serial number in the detail list, etc.
(2) the part drawing, size tolerance, form and position tolerances is adapted to final assembly drawing, parts of material to choose whether or not appropriate, heat treatment and the roughness request is reasonable, the molding parts is easy to wear place is reserved for grinding.
