Description
Technical field
The utility model relates to a kind of injection mold of quick cooling, belongs to injection molding technology field.
Background technology
A kind of processing method used when injection mold (Injectionmold) is some complex-shaped parts of batch production, is mainly used in industrial circle.Injection mold process is that the material melted that is heated is injected die cavity by high pressure, after cooling curing, obtains formed products.Mould is primarily of compositions such as running gate system, forming part and constitutional details.Wherein running gate system running gate system is also known as flow passage system, it is one group of feeding-passage of plastic melt being guided into die cavity by nozzle of injector, usually by sprue, runner, the compositions such as cast gate, sprue connects the one section passage of injection machine nozzle to runner or die cavity in mould, the porch of sprue connects with injection molding machine nozzle, when sprue inlet diameter should slightly larger than nozzle diameter to avoid flash, and intercepting of preventing both from occurring because being connected inaccurate, in addition, the cross-sectional sizes of sprue has a significant impact the flow velocity of fluid in injection moulding process, and rate of flow of fluid directly determines Forming Quality and the production efficiency of plastic products, therefore when using same mould to produce the goods of different materials, because injection raw material changes, the bore of injection molding machine nozzle and all changing to the requirement of flow velocity, if now the import size of sprue is constant, sectional area is constant, then easily there is flash, intercept, sticking to moulds etc. are abnormal.
After injection moulding process terminates, cooling procedure is also very important, and moulded plastic products only has cooling curing to arrive certain rigidity, and plastic products just can be avoided after the demoulding to produce distortion because being subject to external force.Owing to accounting for whole molding cycle about 70% ~ 80% cool time, design cooling system improperly and molding time can be made to elongate, increase cost; The even buckling deformation that more can cause plastic products further of inhomogeneous cooling.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of injection mold of quick cooling, can shortening forming time, improves injection moulding productivity ratio, reduces costs; And can prevent from not mating because of sprue and nozzle or sprue sectional area does not reach and to require and that injection moulding process occurs is abnormal.
For solving above technical problem, the technical solution adopted in the utility model is: a kind of injection mold of quick cooling, comprise dynamic model and cover half, described dynamic model comprises moving platen, be installed on the core rod on moving platen and ejecting mechanism, described moving platen, the cavity formed after cover half and core rod close is die cavity, described cover half is provided with the sprue hole communicated with die cavity, in described sprue hole, close installation has main flow deferent, described main flow deferent is an elongated hollow pipe fitting, one end of described main flow deferent is import, the other end is outlet, the cooling line by the distribution of continuous print zigzag is provided with in described fixed half and moving half plate, described fixed half and moving half plate is provided with inlet and liquid outlet, described cooling line is connected with the coolant apparatus of outside with liquid outlet by described inlet.
The inner surface in described sprue hole and the outer surface of described main flow deferent are provided with the screw thread of mutually occlusion, achieve the compact siro spinning technology of sprue hole and main flow deferent, and when preventing injection moulding, fluid enters seam or main flow deferent is deviate from.
The sectional area of described main flow deferent is increased to Way out gradually by described import, so that the demoulding of runner excrescence.
Described outlet is connected with cast gate, and the sectional area of described cast gate is less than described discharge area, achieves and controls stream speed, and is convenient to goods and is separated with flow passage system.
Described outlet connects with runner, injection moulding while being convenient to carry out multiple die cavity.
The thimble that described ejecting mechanism comprises top board and is connected with top board.
The setting that the utility model adopts sprue hole and main flow deferent to match, can according to the main flow deferent needing the import of replacing different pore size of Shooting Technique, achieve the cooperation from the nozzle of different bore, and can need according to injection moulding the main flow deferent selecting different cross-sectional, to make fluid reach most suitable flow velocity, prevent flash in injection moulding process, intercept, the generation of the abnormal problem such as sticking to mould.
The cooling line of continuous print zigzag distribution, after injection moulding process terminates, can inject cooling fluid in pipeline, cooling fluid distributes rapidly along zigzag pipeline, achieves and mould is evenly lowered the temperature rapidly, and then plastic products in die cavity are evenly lowered the temperature rapidly.
Therefore, the injection mold of a kind of quick cooling provided by the utility model, main flow deferent can be changed as required, be convenient to the injection moulding of the material carrying out different injection moulding requirement on same mould, and after injection moulding completes, evenly can make mould and plastic products cooling rapidly, shortening forming time, improve shaping qualification rate, reduce costs, and structure is simple, durable, is applicable to being applied in Shooting Technique.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
