Description
Technical field
The present invention relates to a kind of technical field of mold, particularly relate to a kind of body feed tank injection mold.
Background technology
Plastic box selects the HDPE(low-pressure high-density polyethylene with high impact) and PP(polypropylene) for raw material injection molded.Plastics box for material circulation extensively has extensive use, facilitate part have enough to meet the need convenient, stack neat, be convenient to management.It reasonably designs, excellent quality, is applicable to the links such as the transport in Factory Logistics, dispensing, storage, circulation and process.Casing technique is once all injection molded mostly, and (the logistics case lid had is supporting separately making, the box for material circulation product that generally all general a few money is of the same type for some plastic box is also supporting case lid.Having plenty of the case lid for designing with a plastic box, is all link with casing or connected as one by other auxiliary accessories and casing).Also some box for material circulation is designed to collapsible style, also reduces logistics cost back and forth when empty van while of can reducing storage volume.Along with developing rapidly of logistic industry and carrier, increasing enterprise applies to plastics box for material circulation, and plastics box for material circulation industry receives the favor of a lot of people.
Finished product shipment is packed, light and handy, durable, can be stacking.Can have all size, size made to order according to user's request, aluminum alloy edge-wrapped, can add a cover, dust-proof, good looking appearance is generous.The size design that general hollow plate container provides according to client makes, and accomplishes the most rationally to load, and can many casees overlapping, effectively utilize hall space, increase parts storage capacity, save production cost.
21 century is environmental protection century, environmental problem day shows important, resource, the energy are more becoming tight, plastic box will welcome new opportunity, also stern challenge will be stood, for adapting to the requirement of New Times, plastic box is except requiring to meet requirement that market packaging quality and benefit etc. improve day by day, also require that it saves the energy, saving resource further, for this reason plastic box forward high function, multifunctionality, environmental protection adaptability, adopt novel raw material, the future developments such as new technology, new equipment and broaden application field.
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.Temperature each point in injection mold is uneven, also relevant with the time point in injection cycle.The effect of die heater keeps temperature constant exactly between 2min and 2max, that is prevents temperature difference to fluctuate up and down in production process or gap.The thermal equilibrium control injection machine of injection mold and the heat transfer of mould are the keys of producing moulding.Mould inside, the heat brought by plastics (as thermoplastic) to the steel of material and mould, passes to heat-conducting fluid by convection current by radiant heat transfer.In addition, heat is passed to air and mould bases by heat radiation.Taken away by die heater by the heat that heat-conducting fluid absorbs.
The existing injection mold for body feed tank processing at present, adding the demoulding in man-hour inconvenience, the process-cycle is long, needs to prune gate materials and recycle.
Summary of the invention
