trim can be divided into four types: left front trim, right front trim, left
back trim, right back trim. As to the material , we often mainly use PP+EPDM-T20,
Because of the assembly , the size
requirement
of trim injection mould is very strict. For example, product surface isn’t
allowed welding line, not allowed pin mark and have high requirement about the strength
and flash not allowed.
Door
trim mould steel material is usually 718H. And door trim mould tooling time is
about 60days. The mould flow will use side fan-shaped gate. Because auto trim
mould is interior parts mould, the function requirement is also very strict. We
would test the product by smell, inflaming retarding, aging resistant,
anti-seismic, low temperature, high temperature and scrape resistance ect.
As
the mould structure:
Firstly,
mould structure conclude hot runner protect guide pin, located ring, clamping
block, pry pit, support plate, eye bolt and cooling line.

mould base requirement as follows:
1.
hot runner guide pin should be 20mm higher than
the nozzle to protect the mould when assembly.
2. Two pry pit
should have a certain space
3. Support plate
should be set.
Mould
design:
1) Auto plastic mould
design is a brain demanding work which has no copy action.
2)
When designing a auto plastic injection mould the method of
modification should be taken into consideration and should have
enough space for modification.
3)
The devices of the auto plastic part injection mould should
meet the standard of anti-grating and long-life shots.
4)
The manufacturing skill and time is different with the hardness and
stretchiness of the material.
5)
Because of its precision, most of work has to be done by manual work.
6) Plastic auto plastic injection mould
of high quality should be qualified with good surface manufacturing and
precision
