Description
Technical field
The present invention relates to a kind of technical field of mold, particularly relate to a kind of front shell of television injection mold.
Background technology
Injection mold is a kind of instrument producing plasthetics; Also be the instrument giving plasthetics complete structure and accurate dimension.A kind of processing method used when injection mo(u)lding is some complex-shaped parts of batch production.The material melted that is heated is injected die cavity by high pressure by concrete finger, after cooling curing, obtains formed products.
Although the structure of mould may be ever-changing because plastics variety and performance, the shape of plastic products and the type of structure and injector etc. are different, basic structure is consistent.Mould forms primarily of running gate system, thermoregulating system, forming part and constitutional detail.Wherein running gate system and forming part are direct contact portion with plastics, and change with plastics and goods, are the most complicated in mold, change maximum, require processing fineness and the highest part of precision.Injection mold is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.When injection moulding, dynamic model and cover half close and form running gate system and die cavity, and during die sinking, dynamic model is separated to take out plastic products with cover half.In order to reduce heavy Design of Dies and manufacturing effort, injection mould have employed standard die set mostly.Running gate system refers to that plastics enter the runner section before die cavity from nozzle, comprises sprue, cold slug well, runner and cast gate etc.Running gate system is also known as flow passage system, and it is one group of feeding-passage of plastic melt being guided into die cavity by nozzle of injector, is usually made up of sprue, runner, cast gate and cold slug well.It is directly connected to Forming Quality and the production efficiency of plastic products.It connects the one section passage of injection machine nozzle to runner or die cavity in mould.Sprue top is spill to be connected with nozzle.Sprue inlet diameter should slightly larger than nozzle diameter (0.8mm) to avoid flash, and intercepting of preventing both from occurring because being connected inaccurate.Inlet diameter is determined according to goods size, is generally 4-8mm.Sprue diameter inwardly should expand the angle in 3 ° to 5 °, so that the demoulding of runner excrescence.Cold slug well it be the hole being located at sprue end, in order to trap the cold burden produced between the double injection of nozzle end, thus prevent the blocking of runner or cast gate.If cold burden is once be mixed into die cavity, then just easily produce internal stress in made goods.The diameter of cold slug well is about 8-10mm, and the degree of depth is 6mm.For the ease of the demoulding, often born by knockout pin bottom it.The top of knockout pin should be designed to tortuous hook-type or set sunken groove, can pull out sprue excrescence smoothly during the demoulding.Runner it be the passage connecting sprue and each die cavity in gang of cavities.For making melt be full of each die cavity with uniform velocity, the arrangement of runner in mold should become symmetrical and equidistantly distribute.The shape and size in the runner cross section difficulty or ease on the flowing of plastic melt, article removal and Making mold have impact.If by the flowing of equal doses, then minimum with the flow passage resistance force of waterproof of circular cross-section.But because the specific surface of cylindrical flow is little, unfavorable to the cooling of runner excrescence, and this runner must be opened on two-half die, not only takes a lot of work but also not easily aim at.Therefore, what often adopt is trapezoidal or the runner of semi-circular cross-section, and is opened on the half mold with knockout pin.Water passage surface polishing must provide filling mold speed faster to reduce flow resistance.The size of runner is decided by plastics variety, the size of goods and thickness.Concerning most of thermoplastic, runner cross-sectional width is all no more than 8m, especially big reached at 10-12m, special little 2-3m.Sectional area should be reduced, in order to avoid increase runner excrescence and extend cool time under the prerequisite of satisfying the demand as far as possible.Cast gate it be connect sprue (or runner) and the passage of die cavity.The sectional area of passage can be equal with sprue (or runner), but usually all reduce.So it is whole flow passage system middle section amass minimum part.The shape and size of cast gate are very large on quality of item impact.In order to meet the requirement of injection technique to mold temperature, needing the temperature of thermoregulating system to mould and regulating.For thermoplastic injection mould, mainly design cooling system and make mold cools down.The conventional way of mold cools down offers cooling-water duct in mould, utilizes the cooling water circulated to take away the heat of mould; The heating of mould except can utilizing cooling-water duct hot water or steam, also can mould inside and around install electrical heating elements.Television cabin generally adopts ABS engineering plastics, i.e. PC+ABS (engineering plastic alloy), at the Chinese name of chemical industry plastic alloy, why called after PC+ABS, be because this material had both had the excellent heat-resisting weatherability of PC resin, dimensional stability and impact resistance, there is again the processing fluidity that ABS resin is excellent.Existing simple for the mach injection mold structure of TV at present, inconvenient operation, crudy is lower.
