Tie up the general 6~12mm of length；In particular cases, to meet mechanical property, fibre length to 25mm.BMC has light, resistance to
Corrosion.The advantages that good insulating, the various free form surfaces of complex contour can be processed, not only meet the requirement of luminous intensity distribution, Er Qiesheng
The reflector of automobile lamps dimensional accuracy of production is high, stability is good.Developed rapidly with the progress and industrial mould of science and technology,
The competitiveness of new product development is increasing, and the requirement to reflector of automobile lamps new product is also increasingly stricter, prior art
Moulding process waste time and energy, production efficiency is low, and percent defective is high, and Product Precision does not reach requirement.Citing is in car light
During BMC mould developments, BMC Jiao Kou positions of the prior art are on the top of product, enter to pour in mould mold-closing injection
The flow of mouth begins to flow into bottom in high point, finally to high-end shaping, such flowing meeting hypertonia, causes mould to bear
Pressure is very big, when mould uses volume production, production repeatedly, die life can be reduced；Easy trapped gas, in mould matched moulds
Under state, because mould is heated mould, cause to have in mould the reserved of hot gas, the presence of a large amount of trachomas is had during formed product, and
Cause to increase with product items cost consumption because artificial manufacturing process is various, precision and safety are but far from meeting market pair
In the requirement of automotive lamp product.
Utility model content
The purpose of this utility model is to provide a kind of BMC mould of car lamp, when reducing injection pressure and the filling of mould
Between shorten, the even heat in mould can spread, and easy-formation, reduce cost of labor, improve the quality of production, operate filling side
Just it is succinct, while friendship phase and quality are can guarantee that, extend the mold use life-span.
For the above-mentioned purpose, major technique solution of the present utility model is to provide a kind of BMC mould of car lamp, including by
Epiplastron, solid plate, die cavity, core, moving platen, support block, ejector retainner plate and the bottom web that top to bottm is sequentially provided with, solid plate are fixed
There is cover half mold insert, moving platen is fixed with the insert that runner is cooperatively formed with cover half mold insert, and solid plate, which is provided with, runs through cover half
Mold insert and the sprue connected with runner, runner are communicated with into cast gate, are entered cast gate and are connected with the middle part of core, ejector retainner plate bottom
End is provided through the injection machine push rod of bottom web.
The sprue is perpendicular to solid plate, and runner is parallel to solid plate.
The solid plate is arranged with two die cavities, and the opening position of corresponding two die cavities of the moving platen is provided with two types
Core.
The sprue is communicated with two runners, and two runners enter cast gate by two respectively and two cores connect
It is logical.
The ejector retainner plate includes upper ejector retainner plate and lower ejector retainner plate.
Cover half thermal insulation board is provided between the epiplastron and solid plate, it is heat-insulated that dynamic model is provided between the support block and moving platen
Plate, keep mould not radiated in preset temperature constant temperature, while do not make injection machine temperature too high, ensure that product quality is stable, prevent
Only machine overheats.
The bottom web is fixed with sprue puller, and ejector sleeve is arranged with sprue puller, and effect is to be sprue in die sinking
Regrinding-material (sprue condensate), which pulls out from sprue bush and regrinding-material is ejected from cold slug well, to be gone, and prevents regrinding-material from entering
Enter die cavity and influence the quality of plastic.
It is the flow for entering cast gate in mould mold-closing injection on the top of product that BMC of the prior art, which enters gate location,
Die cavity bottom is begun to flow into die cavity high point, finally to the high-end shaping of die cavity, such flowing meeting hypertonia, causes mould
It is very big to bear pressure, when mould uses volume production, production repeatedly, die life can be reduced；Easy trapped gas, closed in mould
During mould under state, because mould is heated mould, cause to have in mould the reserved of hot gas, have depositing for a large amount of trachomas during formed product
.After entering gate location change, enter cast gate and fed in the middle part of the side wall of die cavity, the flow of mould is past or so and high in the middle part of die cavity
Low spot flows, and reduces the injection pressure of mould and has shortened the filling time, makes the heat diffusion in mould equal in mold injection
It is even, easy-formation.
The utility model beneficial effect is：The injection pressure and filling time for reducing mould shorten, the heat in mould
It can uniformly spread, easy-formation, reduce cost of labor, improve the quality of production, operation filling facilitates succinct, while can guarantee that friendship
Phase and quality, extend the mold use life-span.
