Surely it is set on solid plate, specifically, in the technical program, the 3D printing mold insert is screwed on solid plate.
The 3D printing mold insert is internally provided with the profile-followed water route of 3D printing, and 3D printing technique can be processed into arbitrary shape, and printing takes
With relatively low, print speed is fast, and the steel material workpiece machinability printed is strong.3D printing technique in the fabrication process will not be by
The constraint of interiors of products structure and complicated shape, by carrying out the complicated design of conformal cooling water route and processing in mould inside,
More can be close to product profile, and be directed to the dead angle of common product or be not easy the region of heat extraction, profile-followed water route can provide good
Radiating efficiency, the cooling effect for having traditional water route incomparable.
In the technical program, the profile-followed water route of 3D printing is preferably screw type water route, the shape of water channel and flowing side
To as shown in figure 4, the both ends in the profile-followed water route of the 3D printing are connected to water inlet 400 and water outlet 500, the 3D printing
The water inlet 400 and water outlet 500 in profile-followed water route communicate, and respectively the place of communicating is equipped with sealing ring to be formed with internal water channel 510
Good circulation waterway, in the technical program, the sealing ring 410 is preferably O-ring seal, and the O-ring seal is rubber
Glue material matter, high resilience and resilience；Appropriate mechanical strength including tensile strength, elongation and tearing toughness etc., makes
It can be stablized with process neutrality, be not easy to be swollen in the medium, thermal pinch（Joule effect）It is small, and easy processing is molded, and can be protected
Accurate size is held, does not corrode contact surface, not pollution medium etc..
The 3D printing mold insert 300 is individually connect with a die heater 100, and 3D printing mold insert internal water channel is given birth in order to prevent
Higher mould temperature is become rusty and needed, therefore uses oil as cooling medium.It is not easy to clearly additionally, due to considering that profile-followed water route is complex-shaped
Water channel dirt is managed, in order to prevent water line block during use, then special filtering net is installed in die heater, so as to filtering off machinery
Impurity, the operating temperature of the die heater 100 is 120~160C °.Plain tubing 200 is additionally provided with outside the mold, it is described general
Oil pipe 200 is connect with the 3D printing mold insert die heater 100 and internal water channel 510.The water route of other cavity parts uses another
An outer die heater controls mold temperature.By carrying out complicated conformal cooling water route design inside inlaid piece of mould and adding
Work, more can be close to product profile, and product surface is uniform, and cooling effect is good, provides good radiating efficiency, have traditional water route without
The cooling effect of method analogy.The structural form in 3D printing water route is substantially equal to the structural form of product, in the production of product
Cheng Zhong ensure that product gate portions heat exchange during cooling down with heating is consistent, effectively reduce the life of mold
The period is produced, mold heating cooling efficiency is improved, ensure that the production stability of mold.
The purpose of the present invention is to provide a kind of flip injection mold that can ensure that product appearance requirement, by the way that system will be poured into a mould
System and ejection system（Pushing block）It is installed in cover half side together, so as to which cast trace and ejection trace be made to be only present in the same of product
One surface can make another surface of product keep better finish, to ensure and meet the requirement of the product appearance of high quality；It and should
3D printing water route is additionally provided on mold, which in use, improves mold heating cooling efficiency, ensure that mold
Production stability.
Still there are many embodiment, all technical sides formed using equivalents or equivalent transformation by the present invention
Case is within the scope of the present invention.
