Shorten its filling time, and fills smooth, injection volume abundance；It is provided with flash road at the both ends of the mode chamber, is conducive to
Molten metal has been filled up completely overflow and exhaust after mode chamber, is unlikely to generate local eddy currents, gas is intracavitary without shape in mode
At high pressure, the problems such as not will cause product air holes cavity blemish sand hole.
Further, a plurality of mode chambers symmetrical formula arrangement in rear cavity, is preferably arranged 4 modes
Chamber.Symmetrical expression setting mode chamber, can rationally make full use of the surface area of rear cavity, also be conducive to the distribution in charge road and flash road
Arrangement, while also reducing the difficulty of the actual production processing of rear cavity.
Further, a plurality of mode chambers both ends flash road includes plural flash road tributary, wherein a flash
Road tributary is communicated with the charge road.Plural flash road tributary is set, is conducive to the intracavitary gas of mode and is quickly discharged.
Further, groove is provided on flash road tributary.The setting of the groove, can be with the stream of buffer metal liquid
Dynamic rate, while being also conducive to exhaust.
Further, be provided with confluence road in the middle part of the rear cavity, the confluence road with a plurality of mode chambers one
The flash road at end communicates.In the middle part of rear cavity setting confluence road, be conducive to metal in the flash road of the intracavitary side of mode and
The discharge of gas.
Further, the depth in the confluence road is deeper than the depth in the flash road, and the bottom in the confluence road is in ladder
Shape.The depth in confluence road is stepped compared with the bottom of the depth in flash road depth and the road that converges, and has the confluence of interests molten metal to assemble,
Its quality can be influenced to avoid product is entered into mode chamber molten metal in early days, and be also beneficial to overflow and the discharge mould in flash road
The intracavitary extra gas of benevolence,
Further, the quadrangle corner of the rear cavity is provided with fixed lobe.It can be by opposite with rear cavity
Fixed groove corresponding with fixed lobe is set in the front cavity answered, passes through fixed lobe, the fixed groove on forward and backward mode
Mutual cooperation, reach positioning and fixed effect.
The advantage of the utility model is, a kind of motorcycle end cap exhaust die casting of the utility model, using originally making
