The invention discloses a die used for a plastic wheel hub cover. The die comprises a front die and a rear die which are mutually matched, wherein the front die and/or the rear die are/is provided with cooling water route runners; the front die and the rear die are both circular; the cooling water route runners are distributed along the radial direction and/or an annular shape; the front die and the rear die are formed by splicing a plurality of inserts; the inserts are fixed to die plates; fixing plates are arranged around the inserts. According to the die used for the plastic wheel hub cover, the cooling water route runners are arranged in the front die and/or the rear die, the cooling of the die is realized, the product surface defect caused by local overheat and an air trapping fault is avoided in an injection molding process, the quality of a plastic wheel hub is improved, the structure is simple, and the implementation is easy. In addition, the cooling water route runners are reasonably arranged, exhaust holes are formed, and the center of a die core is made of a beryllium copper material, so that the radiating effect is further improved.
Description
Technical field
The present invention relates to a kind of mould for auto parts and components, particularly relate to a kind of mould for plastic wheel hub cover.
Background technology
Wheel hub, English name: WheelHub, in automobile tire centered by axle for the cylindrical metal parts of support tire, generally, being exactly the position that wheel center installs axletree, is the important spare part connecting brake drum (brake disc), wheel disc and semiaxis.Automotive hub is an important component part of auto parts and components, and along with the growth of Chinese automobile Parts mapping, wheel hub industry is developed gradually.Since showing 2010 according to " prediction of 2013-2017 Chinese automobile wheel hub industry market is reported with investment strategy planning application " data, the macro economic policy based on promote domestic demands, for the stable development of automobile industry provides the foundation and guarantee.From automobile market tendency in 2010, the impact of macro economic policy on automobile market has run through the whole year, annual automobile volume of production and marketing reaches 1826.47 ten thousand and 1806.19 ten thousand respectively, and production and marketing creates the highest again, and continues to keep the first in the world automobile production and country of consumption status.Within 2011, economic continuation keeps steady growth, and automobile production and marketing situation is expected to continue to obtain larger amplification; Within 2011, Chinese automobile output is expected to breakthrough 2,000 ten thousand, within 2015, reaches 2,500 ten thousand.On long terms, the quick growth of China's GDP is that automobile industry provides wide demand space, and the growth with automobile sales volume increases by the demand of automotive hub.A few years from now on Chinese automobile sales volume is expected to sustained, stable growth, for automotive hub industry provides the opportunity of development.
Be be connected by screw locking between wheel hub with truck drive shaft, so get rusty to prevent screw from polluting at first, people increase a protective cover at hub surface, and this is initial wheel hub cover.
Along with the maturation of automobile industry, people require also to improve gradually to each side such as outward appearance, quality, price, experience of automobile, wheel hub cover is as an important appearance member, on the basis retaining original function, also simultaneously more complicated towards structure, moulding is more attractive in appearance, cost is more economical, the more convenient future development of dismounting.
The material of conventional boss lid is cast iron, aluminium alloy, stainless steel etc., and novel hub lid adopts the material such as ABS, PC/ABS to replace, performance gap major embodiment between the two in the following areas:
Plastic wheel hub problem is in the market as follows: because the shrinkage character of plastics self, the fault of hot-spot and tired gas is easily there is in it in injection moulding process, cause product surface to exist because cooling meat is uneven and bad concavo-convex, the current mark defect caused of exhaust, thus have impact on the presentation quality of plastic wheel hub.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of mould for plastic wheel hub cover, can avoid the surface defects of products caused because of hot-spot and tired gas fault in injection moulding process, improves the quality of plastic wheel hub, and structure is simple, easy to implement.
The present invention solves the problems of the technologies described above the technical scheme adopted to be to provide a kind of mould for plastic wheel hub cover, and comprise front mould and the rear mold of coupling mutually, wherein, described front mould and/or rear mold are provided with cooling water channel runner.
The above-mentioned mould for plastic wheel hub cover, wherein, described front mould and rear mold are toroidal, described cooling water channel runner radially and/or circumferential direction distribution.
The above-mentioned mould for plastic wheel hub cover, wherein, described front mould and rear mold assembled by multiple mold insert, described multiple mold insert is fixed in template, and the surrounding of described multiple mold insert is provided with fixed head.
The above-mentioned mould for plastic wheel hub cover, wherein, described front mould is assembled by the mold insert that 8 shape sizes are identical.
The above-mentioned mould for plastic wheel hub cover, wherein, described rear mold is assembled by the mold insert that 8 shape sizes are identical.
The above-mentioned mould for plastic wheel hub cover, wherein, the material of described front mould and rear mold core is beryllium copper.
The above-mentioned mould for plastic wheel hub cover, wherein, the excircle of described front mould and rear mold is radially formed with steam vent.
The above-mentioned mould for plastic wheel hub cover, wherein, described front mould is provided with ejector retainner plate.
The present invention contrasts prior art following beneficial effect: the mould for plastic wheel hub cover provided by the invention, mold cools down is realized by arranging cooling water channel runner on front mould and/or rear mold, thus avoid the surface defects of products that causes because of hot-spot and tired gas fault in injection moulding process, improve the quality of plastic wheel hub, and structure is simple, easy to implement.In addition, the present invention, by reasonable Arrangement cooling water channel runner, arranges steam vent, and die center adopts beryllium copper material, improves radiating effect further.
