Die sinking sequence be:Plastic melt is injected from main cast gate, is flowed into cavity by runner and cast gate, when plastic melt is noted Man Hou, product profile are formed, and die sinking action is then carried out, and are opened when molding between stripper plate and preceding mould mold insert fixing plate, real Now first time parting makes cast gate be detached with product;Stripper plate and preceding baffle plate are molded again to separate, and are realized second of parting, are made Main cast gate is detached with sprue bush, then die sinking is separated between front template and rear pattern plate, is realized third time parting, is made front and back mould It separates, product is from rear moulding/demoulding, mould side before staying in, and then the first oil cylinder and second the first sliding block of hydraulic oil cylinder driving and the second sliding block are taken out Core realizes product side core-pulling, then mold by rear pattern plate drive pull rod by front template and pushing block and preceding mould mold insert fixing plate it Between separate, realize the 4th parting, product is detached from core, to realize product depanning.
Molding sequence:Before molding, the first oil cylinder of both sides and the second oil cylinder pushing sliding block return, then injection molding machine carry out again Molding.
3D printing mold insert and internal water channel are additionally provided on the mold, as shown in Figure 3 and Figure 4, the 3D printing mold insert is solid Surely it is set on solid plate, specifically, in the technical scheme, 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 scheme, the profile-followed water route of the 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 are communicated with internal water channel 510, and respectively the place of communicating is equipped with sealing ring to be formed Good circulation waterway, in the technical scheme, the sealing ring 410 are preferably O-ring seal, and the O-ring seal is rubber Glue material matter, high resilience and resilience;Mechanical strength appropriate, including tensile strength, elongation and tearing toughness etc. make 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 protect 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 The operating temperature of impurity, the die heater 100 is 120~160C °.It is additionally provided with plain tubing 200 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 is 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 this utility model is to provide a kind of flip injection molds that can ensure that product appearance and require, by that will pour Injection system and ejection system(Pushing block)It is installed in cover half side together, to make cast trace and ejection trace be only present in product Same surface, another surface of product can be made to keep better finish, to ensure and meet the product appearance requirement of high quality; And 3D printing water route is additionally provided on the mold, which in use, improves mold heating cooling efficiency, ensure that The production stability of mold.
Still there are many embodiment, all technologies formed using equivalents or equivalent transformation for the utility model Scheme is all fallen within the scope of protection of the utility model.
