Further, it is symmetrically arranged with some boss about adjacent cross pouring basin in described lower impressions.
By such scheme, being provided with so that generating some grooves in the bottom of product for position of described boss, it is possible not only to effectively avoid the shrinkage porosite phenomenon of product, it is also possible to save material.
Further, two boss symmetrical about adjacent described cross pouring basin are provided with the first locating dowel.
By such scheme, described first locating dowel is for the location of guide ring inner casts sheet.It is provided with Blind locating holes in advance on guide ring foundry goods sheet, during injection, described Blind locating holes is directed at the first locating dowel, quick Set and Positioning can be realized.
Further, it is provided with the second locating dowel between described first locating dowel and boss.
Pass through such scheme, for making described definition locating dowel the Blind locating holes grafting quickly and on guide ring foundry goods sheet to position, between described first locating dowel and Blind locating holes, it is typically all matched in clearance, so, foundry goods sheet will produce inclination in the first locating dowel, affects product quality.To this end, arrange the second locating dowel between described first locating dowel and boss so that foundry goods sheet can be played a supporting role by the bottom of foundry goods sheet with the second locating dowel upper surface.
Further, the middle part of the sidewall of described injection molding body is vertically arranged fluted.
By such scheme, the setting of described groove facilitates dismounting and the replacing of injection molding body, and beneficially matched moulds time fixed half and moving half between the discharge of air.
Further, four vertical ribs of described injection body cavity are provided with semicircular enlarging groove.
By such scheme, described enlarging groove has two effects, and one is in order to avoid when described injection molding body is embedded cover half, four vertical seamed edges of injection molding body are stuck on described injection body cavity 11 corner angle the installation inconvenience caused；Two are easy for the discharge of air between die face.
Further, being provided with pilot hole on four angles of described cover half, the correspondence position at described dynamic model is provided with lead.
By such scheme, described dynamic model and cover half is made can quickly to position and be combined together by described pilot hole and lead to dynamic model guiding.
In sum, this utility model has the advantages that
1, the air chamber between described inverted trapezoidal wall can allow matched moulds time die cavity in the middle part of air be squeezed entrance air chamber in, reduce the air impact on product surface quality；
2, described first locating dowel and the second locating dowel are for the location of guide ring gradually sheet and support so that it is be in level, it is ensured that product quality.
