The specific embodiment
Referring to Fig. 1～Fig. 4, the embodiment that waters the structure of fixing braking inserts on the injection molding for a kind of casting hub comprises patrix 1, counterdie 9.Described patrix core 3 is provided with the spacing end face 4 to braking inserts 2 axial limitings, and in assembling braking inserts 2, described spacing end face 4 can carry out axial location to braking inserts 2.The outer circumference surface of the patrix core 3 of described patrix 1 arranges radial hole 15, the quantity of described radial hole 15 is at least three, a plurality of radial holes 15 are uniformly distributed in the inserts fixed cylinder face circumference of patrix core 3, and common group number by patrix core reinforcement arranges radial hole in the industrial practice.Be provided with successively Compress Spring 7 and elasticity fore-set 6 in the described radial hole 15, the quantity of described elasticity fore-set 6 is identical with the quantity of radial hole 15.Described Compress Spring 7 is resistant to elevated temperatures Compress Spring, to guarantee that Compress Spring 7 can work in casting process.After assembling braking inserts 2, the elasticity fore-set 6 in a plurality of radial holes 15 props up fixing braking inserts 2 simultaneously, makes braking inserts 2 stress equalizations, and braking inserts 2 is concentric with patrix core 3.The bottom of described elasticity fore-set 6 is provided with for the hole that Compress Spring 7 is installed, and Compress Spring 7 is positioned at this hole, and described elasticity fore-set 6 is slidingly matched with patrix core 3, and this elasticity fore-set 6 can move back and forth along the radial hole 15 of patrix core 3 under the effect of Compress Spring 7.Elasticity fore-set 6 radially be provided with guide and limit hole 14, an end of guide and limit pin 5 inserts in this guide and limit hole 14, the other end of described guide and limit pin 5 is threaded with the patrix core.Described guide and limit hole 14 is bar hole, large 0.02～the 0.04mm of guide and limit pin diameter that the Width of bar hole inserts, leave elasticity fore-set 6 axially movable distances between the hole wall in guide and limit pin 5 and guide and limit hole 14, the length direction of bar hole is mainly used to control maximum overhang and the maximum indentation amount that plays top sliding block, make elasticity fore-set 6 extended patrix core 3 outer circumference surfaces under the effect of Compress Spring 7, when not packing inserts into, elasticity fore-set 6 its maximum overhang under the effect of Compress Spring 7 and guide and limit pin 5 is 0.5mm.This guide and limit pin 5 can be to elasticity fore-set 6 guiding, makes the elasticity fore-set 6 can only oriented sliding, and prevents that this elasticity fore-set 6 from rotating.Described elasticity fore-set 6 is cylindrical, and the upper and lower of elasticity fore-set 6 rear ends is respectively equipped with cuts off plane 13, and guide and limit hole 14 is located at and is cut off in the plane 13.Friction area between elasticity fore-set 6 and the patrix core 3 has been reduced on the
