The cost-saving injection die provided by the invention has the advantages that the labor production efficiency is improved, the investment cost is lowered, and the running cost is reduced.

Description

Cost-saving injection mold
Technical field
The present invention relates to a kind of cost-saving injection mold.
Background technology
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.For the mould parts that hardness is very high, adopt machined way to process, mostly adopt spark machined, in addition also spark machined is used for the wedge angle of mold cavity, deeply position, chamber, narrow groove etc.And numerically controlled lathe is mainly for processing mold bar class standard part, and the mold cavity of revolving body or core, as the injection mold of bottle, dishware, the forging die of axle class, disk-like accessory.In Mould Machining, the application of numerical control drilling machine also can play the effect improving machining accuracy and shorten the process-cycle.Mould is widely used, the product members formed machining in modern manufacturing industry, nearly all needs to use mould.So Die Industry is the important component part of national new high-tech industry, it is important, valuable technical resource.Optimize the CAD/CAE/CAM of mold system structural design and shaped piece, and make it to be tending towards intelligent, improve shaped piece formed machining technique and mould standard level, improve Making mold precision and quality, reduce shaped piece surface grinding, polishing operation amount and manufacturing cycle; Study, apply the high-performance adopted for various types of mould shaped piece, free machining proprietary material, to improve mould serviceability; For adapting to market diversification and trial production of new products, application RP technique and Rapid tooling, to manufacture form die, injection molding or compression mod etc. fast, should be the development trends of the mould production technology of following 5-20.
Summary of the invention
The object of the present invention is to provide a kind of cost-saving injection mold, have and improve labor productivity, reduce cost of investment, decrease the advantages such as operating cost.
Technical scheme of the present invention is: a kind of cost-saving injection mold, described cost-saving injection mold comprises patrix, detent mechanism and counterdie, the two ends of described patrix and described counterdie are all provided with groove, described column is fixed in described groove, described detent mechanism is fixedly installed in the centre position of upper die and lower die, and described detent mechanism comprises locating piece and limited block.
In a preferred embodiment of the present invention, between described locating piece and limited block, be provided with wearing plate.
In a preferred embodiment of the present invention, the number of described column is 2.
A kind of cost-saving injection mold of the present invention, has and improves labor productivity, reduces cost of investment, decreases the advantages such as operating cost.
Accompanying drawing explanation
Accompanying drawing 1 is the perspective view of cost-saving injection mold one preferred embodiment of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, patrix, and 2, counterdie, 3, column.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, Fig. 1 is a kind of cost-saving injection mold of the present invention, described cost-saving injection mold comprises patrix 1, detent mechanism and counterdie 2, the two ends of described patrix 1 and described counterdie 2 are all provided with groove, described column 3 is fixed in described groove, and described detent mechanism is fixedly installed in the centre position of patrix 1 and counterdie 2, and described detent mechanism comprises locating piece and limited block, be provided with wearing plate between described locating piece and limited block, the number of described column 3 is 2.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 (O.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.It is the hole being located at sprue end, in order to trap the cold burden produced between the double injection of nozzle end, thus prevents 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.Diameter about 8 one lOmm of cold slug well, 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.It is 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, and especially big reaches 10 1 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.The invention provides a kind of cost-saving injection mold, have and improve labor productivity, reduce cost of investment, decrease the advantages such as operating cost.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
