Description
Technical field
The utility model relates to a kind of technical field of mold, particularly relates to a kind of down stream tee joint injection mold.
Background technology
Down stream tee joint is a kind of pipe fitting in discharge pipe line.For the vertical connection of arm with main.Although be vertical connection, the junction that arm enters main does not intersect vertically, but connect by a bit of circular arc flow direction downstream, so just make the water of arm flow to main very smoothly.This bit of circular arc is exactly the effect served downstream.The size length of the circular arc downstream of different producer's designs is different, but circular arc downstream must be had just to be called down stream tee joint.Down stream tee joint comprises into water adapter and water outlet adapter, and water inlet adapter is communicated with water outlet adapter vertical eccentric, and it is characterized in that the axis of water inlet pipe along outlet pipe in water pipe extends to form inner connecting tube, inner connecting tube and water outlet form empty wall between taking over.Water project situation: 90 ° of skew T > down stream tee joints, common material: 45 ° of skew Ts can metal material also can plastic material, 90 ° of skew T metal materials, down stream tee joint plastic material.
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.Injection mold divides into two kinds, thermosetting plastic mould, thermoplastic plastic's mould according to shaping characteristic; Divide into according to moulding process and pass mold, blow molding die, draw mould, thermoforming mould, hot-die (compression mould), injection mould etc., wherein hot-die can be divided into again excessive formula, half excessive formula, excessive formula three kinds in flash mode, and injection mould can be divided into again cold flowing mould channel, hot runner mould two kinds with running gate system; With can be divided into by handling mode movable type, fixed two kinds.
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.
Injection device injects device in mould after resin material being heated melt.From stub bar, resin is clamp-oned barrel as shown in the figure, by the rotation of screw rod by melt Conveying to the front end of machine barrel.In that process, under the effect of heater, heating makes the resin material in machine barrel be heated, under the shear stress of screw rod, make resin become molten condition, products formed and sprue will be equivalent to, the molten resin of runner is stranded in the front end (being referred to as metering) of machine barrel, and material is injected die cavity forward by the continuous of screw rod.
When molten resin flows in mould, the translational speed (issuing velocity) of screw rod must be controlled, and control with pressure (packing pressure) after resin is full of die cavity.Work as screw position, when injection pressure reaches certain value, speeds control can be switched to Stress control by us.
Injection mold is the important process equipment producing various industrial products, along with developing rapidly of plastics industry, and plastic products applying at industrial departments such as Aeronautics and Astronautics, electronics, machinery, boats and ships and automobiles, the requirement of product to mould is also more and more higher, traditional die design method cannot adapt to current requirement. compared with traditional Design of Dies, no matter computer-aided engineering (CAE) technology is boosting productivity, ensureing in product quality, or in reducing costs, reducing labor intensity, all there is great superiority.Injection mold work in-process, various digital control processing is all used, applying maximum is numerical control mill and machining center, the application that Numerical Control Wire Cutting and numerical control electric spark are processed in die numerical control is processed is also very general, Linear cut is mainly used in the Mould Machining of various straight wall, as the concave-convex mold in punch process, the insert in injection mould, slide block, the electrode etc. of spark machined.The existing injection mold structure for down stream tee joint processing is complicated at present, and inconvenient operation, working (machining) efficiency is not high.
