Present invention is disclosed the injection molds that a kind of flip-over type carries the profile-followed water route of 3D printing, as depicted in figs. 1 and 2, should Mold 1 includes the preceding mould being mutually matched and rear mold, and baffle plate and front template 15 before being provided on each preceding mould are each described Mould mold insert before being provided on front template, it is solid on the front template 15 before the preceding mould mold insert is fixed in mould mold insert fixing plate 16 Surely it is provided with a pushing block 5 for product to be ejected.
Rear baffle plate and rear pattern plate 19 are provided in each rear mold, each rear pattern plate is fixed on rear baffle plate On, mold core and rear cavity 17 are provided on each rear pattern plate, the rear cavity 17 is fixed on rear pattern plate, in this technology side In case, the rear cavity 17 is screwed on rear pattern plate, and rear mold pin, the rear mold edge are provided in the rear cavity Needle 18 is fixedly installed in rear cavity 17, and each preceding mould mold insert and each rear mold mold insert and sliding block match to be formed to note Mould molding mold cavity 2.
The preceding mould is equipped with the main cast gate 8 being connect with injection machine, and the main cast gate 8 is connected with runner 9, the stream Road 9 is connected by cast gate with mold cavity, and sprue bush 7 is fixedly installed in the preceding mould fixed plate.
The first sliding block 12, the second sliding block 13, the first oil cylinder 10 and the second oil cylinder 11, institute are symmetrically arranged on the front template The first sliding block 12, which is stated, with the first oil cylinder 10 is fixedly connected by T-slot;Second sliding block 13 and the second oil cylinder 11 are to pass through T-slot It is fixedly connected, 12 and first oil cylinder 10 of the first sliding block is synchronized with the movement;Second sliding block 13 does synchronous fortune with the second oil cylinder 11 It is dynamic, specifically, T-slot, 10 and second oil cylinder of the first oil cylinder are offered on 12 and second sliding block 13 of the first sliding block The convex block to match with T-slot is respectively and fixedly provided on 11.
Stripper plate 3 is provided between the front template 15 and preceding baffle plate 6, being provided with 4 in the preceding mould fixed plate leads Column, the stripper plate 3, preceding mould mold insert fixing plate 16 and front template 15 slide on guide post.Pull rod is additionally provided on the mold 14, one end of the pull rod 14 is fixed on front template 15, and the other end is fixed on rear pattern plate.
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 then carry out die sinking action, 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 arrived between front template and rear pattern plate and separated, and is realized third time parting, is made front and rear 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, so as to fulfill 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 consolidated 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.
