The mold structure is like playing chess.
There is no game in the ages. Each set of molds is different, and the mold structure is
ever-changing. In particular, some complex molds and automobile molds have very classic
structures. For molders, they are happy to hunt, and they want to watch and learn and
challenge when encountering complex and special molds. This is a common feature of
molders. On the complexity of the mold structure: the automobile exterior structure is led
by the bumper, the automobile interior decoration is led by the instrument, and the
automobile structural parts should be led by the automobile air conditioning and intake
manifold. In addition, the molds for housings, home appliances, and office supplies are
also quite distinctive. Today, I will use a set of car rearview mirror molds to analyze
the mold structure in detail.
This product is the mirror holder on the rearview
mirror of the car, the material is ABS, the product is left and right mirror parts, and
the number of mold cavities is 1+1.
product analysis
Car rearview mirror is an
important part of car exterior parts, located on both sides of the car, is one of the most
important exterior parts of the car. The rearview mirror of a car is a device used to
allow the driver to observe the road conditions during driving, which can be said to be
the driver's eyes. Automobile rearview mirrors are generally composed of mirror ring,
base, mirror housing, bracket, rotating shaft and other parts.
If this product is
based on the general product analysis thinking, if the direction of the posterior mold
bone or column is the main ejection direction, the mold structure will inevitably be
complicated, and a large number of undercuts will be generated, resulting in many and
complex mold structures.
Therefore, choosing the spindle hole position as shown in the
figure below as the main ejection direction will make the mold structure simpler than the
above. The side adopts an oblique row core-pulling structure, and a thimble, a cylinder,
etc. are required in the row position.

This mold gating system adopts
hot runner injection, and adopts a 1-point open hot runner + cold runner + side gate
injection method.

There are undercuts on the inner and outer sides
of the product, and the cylinder core is used for core pulling, and the outer side
structure is also used for cylinder core pulling
