Upper cavity 5 is opened on patrix 1.Upper mold core 3 is fixed on patrix 1, is arranged in upper cavity 5.
Lower mode cavity 6 is opened on counterdie 2.Lower mold core 4 is fixed on counterdie 2, is arranged in lower mode cavity 6.
Patrix 1 and counterdie 2 are fixed.
Upper mold core 3 and lower mold core 4 are oppositely arranged, and both enclose and form product die cavity 7.
Upper cavity 5 and lower mode cavity 6 are oppositely arranged and communicate.
Have running channel 8 in compression mod, the surface of mold has sprue gate 9, and one end of running channel 8 is communicated with sprue gate 9, and the other end is communicated with the feeding mouth of product die cavity 7.Aluminium water enters product type chamber 7 from sprue gate 9 after running channel 8, is molded into product (motor bottom end cover) in product die cavity 7.Waste material also flows in sprue gate 9 from product die cavity 7 through running channel 8.
Running channel 8 is divided into the first running channel section 12, second running channel section 13, the 3rd running channel section 14, first running channel section 12, second running channel section 13, the 3rd running channel section 14 to be communicated with successively.First running channel section 12 is vertical with the 3rd running channel section 14, is easier to running channel layout in compression mod like this, is also convenient to product die cavity 7 and the design to sprue gate 9.
Material cover 10 is fixed on patrix 1.Have material trepanning 11 in material cover 10, material trepanning 11 front portion is cylindrical, and the head that material trepanning 11 front portion forms the first running channel section 12, first running channel section 12 is communicated with sprue gate 9.Material trepanning 11 rear portion is conical.
The afterbody of supercharging cone 15 is fixed on counterdie 2.Supercharging cone 15 docks with material cover 10, and its head is arranged in the rear portion of material trepanning 11.The head of supercharging cone 15 is taper, a part for the head outer wall of supercharging cone 15 is fixed with a part for the rear portion hole wall of material trepanning 11, the head that remainder and the remainder of the rear portion hole wall of material trepanning 11 of the head outer wall of supercharging cone 15 enclose formation second running channel section 13, second running channel section 13 is communicated with the afterbody of the first running channel section 12.The tapering width of the second running channel section 13.
Have the 3rd running channel section the 14, three running channel section 14 in core rod and comprise direct current section 21 and ring segment 22, direct current section 21 is cylindrical, and ring segment 22 is annular.The head of direct current section 21 is communicated with the afterbody of the second running channel section 13, and the afterbody of direct current section 21 is communicated with the peripheral part of ring segment 22.The feeding mouth of product die cavity 7 is annular, and the inner peripheral portion of ring segment 22 is communicated with the feeding mouth of product die cavity 7, such structure, makes product die cavity 7 can obtain filling fast, equably, can improve product quality.The tapering width of the inner peripheral portion of ring segment 22.
Aluminium water is introduced in the first running channel section 12 from sprue gate 9, is cushioned in the first running channel section 12, makes the flow velocity of aluminium water even.After aluminium water enters the second running channel section 13, due to the tapering width of the second running channel section 13, aluminium water obtains supercharging in the second running channel section 13, and flow velocity is accelerated.To get back when aluminium water enters the direct current section 21 of the 3rd running channel section 14 buffering, make the flow velocity of aluminium water even; And aluminium water is when entering the inner peripheral portion of ring segment 22, the tapering width of the inner peripheral portion of ring segment 22, aluminium water obtains supercharging again, and flow velocity is accelerated, and then pours product die cavity 7.This spline structure, aluminium water flow velocity through evenly, accelerate, evenly, the process accelerated, the aluminium water flow velocity poured in product die cavity 7 is made to control a more rational scope, can not be too fast and produce bubble due to flow velocity, also can not can not cause defects such as causing misrun, crystal grain uniformity poor by filling product die cavity 7 completely because flow velocity crosses slow.
