Described upper die body is semicircular upper semi-circle housing by cross section, two upper semi-circle flanges that upper semi-circle housing two ends are welded mutually therewith respectively formed with two longitudinal docking lower platens that the longitudinal both sides of upper semi-circle housing are welded mutually therewith respectively, described two lower surfaces longitudinally docking lower platen are equipped with longitudinally elongated positive stop lug boss, and described two longitudinally the both ends of the surface of docking lower platens be abutted against mutually with described two upper semi-circle flanges and connect, the top of described upper semi-circle housing is provided with sprue gate, the elongated positive stop lug boss of described longitudinal direction plugs with the corresponding through limited impression of longitudinal direction be positioned at below.
Described sprue gate is elongate strip form, and this sprue gate length is the 85%-95% of upper semi-circle housing overall length, and the width at this sprue gate is the 20%-30% of upper semi-circle shell inner surface radius.
Described upper semi-circle housing, the inner surface of lower half circle housing are provided with chromium plating slippery inner surface layer.
The utility model has features:
1, the utility model is sectional die, and can produce the finished parts of several same specification finished parts or different size, production efficiency is high simultaneously;
2, the utility model dies cavity establishes chromium plating slippery inner surface layer, can facilitate brushing releasing agent and inner wall washing, and the easily demoulding, easy to operate, finished appearance quality;
3, sprue gate of the present utility model is elongate strip form, and sprue gate can be vented simultaneously, product material inner homogeneous bubble-free.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A sectional view of the present utility model.
Fig. 3 is the B place partial enlarged drawing of the utility model Fig. 2.
Detailed description of the invention
