Abstract
The utility model relates to the technical field of a transmission system of a diesel locomotive, in particular to a precision casting mould for an arc elbow of a diesel engine. The precision casting mould comprises an upper mould, a lower mould, a straight core, a revolution arc core and a revolution rod, wherein the upper mould and lower mould are connected as an assembly through a bolt; the straight core is inserted at the left end of the assembly; the revolution arc core is inserted at the lower end of the assembly; the revolution rod is rotatably connected with the assembly through a hinge pin; and the tail end of the revolution arc core is connected to the revolution rod. A horizontal split type lost-wax mould is adopted, and the revolution arc core performs revolving core pulling by use of the lever principle; and the precision casting mould has a light and compact structure, reliable guide and visual and easy core removal, adopts a powerless, safe, labor-saving and efficient production mode, ensures the mould precision and has long service life.
Description
Technical field
The utility model relates to diesel locomotive transmission system technical field, especially a kind of diesel engine circular arc bend pipe finish cast die.
Background technology
For guaranteeing the railway high speed traffic safety; Diesel engine arc bend tube-surface quality and cleaning inside degree in the diesel locomotive are had higher requirement; Present diesel engine circular arc bend pipe is a normal steel casting spare, adopts sand casting, rough surface; Low precision is prone to produce defectives such as sand washing, burning into sand and pore.
The utility model content
Existing diesel engine circular arc bend pipe ordinary sand casting foundry goods is coarse in order to overcome, the deficiency of low precision, and the utility model provides a kind of diesel engine circular arc bend pipe finish cast die.
The utility model solves the technical scheme that its technical problem adopted: a kind of diesel engine circular arc bend pipe finish cast die; Comprise upper die and lower die, straight core, revolution circular arc core and pivoted lever; Upper die and lower die connect into assembly through bolt, and straight core is inserted in the left end of assembly, and revolution circular arc core is inserted in the lower end of assembly; Pivoted lever is rotatably connected with assembly through bearing pin, and the end of revolution circular arc core is connected on the pivoted lever.
According to another embodiment of the utility model, comprise that further bearing pin is embedded in the assembly, lower end and counterdie fit, the upper end is through axle sleeve and patrix fit.
According to another embodiment of the utility model, comprise that further an end of pivoted lever is enclosed within on the bearing pin, the other end is provided with handle.
According to another embodiment of the utility model, comprise that further revolution circular arc core is connected with pivoted lever through shop bolt.
According to another embodiment of the utility model, comprise that further straight core is provided with alignment pin.
According to another embodiment of the utility model, further comprise being respectively equipped with regulating block on the upper die and lower die, and connect through bolted.
The beneficial effect of the utility model is that mould adopts horizontal parting dewax mould, turns round the circular arc core and utilizes lever principle, turns round and looses core; The light and handy tight Qi of structure, guiding is reliable, and depoling is intuitively simple and easy; Unpowered, safe, laborsaving, High-efficient Production pattern guarantee mould and die accuracy, long service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the side view of the utility model.
1. patrixes among the figure, 2. counterdie, 12. assemblys, 3. straight core, 4. revolution circular arc core, 5. pivoted lever, 6. bearing pin, 7. axle sleeve, 8. handle, 9. shop bolt, 10. alignment pin, 11. regulating blocks.
The specific embodiment
Like Fig. 1 is the structural representation of the utility model, and Fig. 2 is the side view of the utility model, a kind of diesel engine circular arc bend pipe finish cast die; Comprise patrix 1, counterdie 2, straight core 3, revolution circular arc core 4 and pivoted lever 5; Patrix 1 connects into assembly 12 with counterdie 2 through bolt, and straight core 3 is inserted in the left end of assembly 12, and revolution circular arc core 4 is inserted in the lower end of assembly 12; Pivoted lever 5 is rotatably connected with assembly 12 through bearing pin 6, and the end of revolution circular arc core 4 is connected on the pivoted lever 5.Bearing pin 6 is embedded in the assembly 12, lower end and counterdie 2 fits, and the upper end is through axle sleeve 7 and patrix 1 fit.One end of pivoted lever 5 is enclosed within on the bearing pin 6, and the other end is provided with handle 8.Revolution circular arc core 4 is connected with pivoted lever 5 through shop bolt 9.Straight core 3 is provided with alignment pin 10.Be respectively equipped with regulating block 11 on patrix 1 and the counterdie 2, and connect through bolted.
This finish cast die is a horizontal parting dewax mould, the light and handy tight Qi of structure, and guiding is reliable, and depoling is intuitively simple and easy, when loosing core, takes out straight core 3 earlier, draws back and changes circular arc core 4; Because the end of revolution circular arc core 4 is connected on the pivoted lever 5, an end of pivoted lever 5 is enclosed within on the bearing pin 6, and the other end is provided with handle 8, through rotating back to bull stick 5, can extract revolution circular arc core 4 simply and easily out; And handle 8 adjustable length are controlled laborsaving; Regulating block 9 can suitably be regulated product allowance, anti-deformation, improves the quality.This finish cast die production efficiency is high, and percent defective is low, and economic benefit is obvious, and certain promotion value is arranged.
