Casting die includes positioning pin, briquetting and foam, the upper end of the briquetting by positioning pin be fixedly mounted on lower section hollow part it is interior
The lower end surface in portion, the briquetting is fixed with foam.
Further, the inside of the hollow part of top is equipped with idler wheel by wheel shaft, and the upper end of idler wheel protrudes from
The upper surface of forced section.
Further, the interconnecting piece is the relatively thick intermediate thinner hourglass shape in both ends.
Further, the positioning pin is bolt, and is lock state between positioning pin and briquetting.
Compared with prior art, the utility model has the beneficial effects that 1, the utility model is provided with casting die, under casting die
The contact area of bottom surface and piston increases, and then the forced area of piston upper surface increases, so that even piston stress, guarantees to live
The planarization of end face beyond the Great Wall；
2, whole device is divided into mounting portion, interconnecting piece and forced section, the overall volume of interconnecting piece is smaller, and then saves former
Material reduces production cost.

Specific embodiment
It is practical below in conjunction with this to keep the purposes, technical schemes and advantages of the utility model embodiment clearer
The technical solution in the utility model embodiment is clearly and completely described in attached drawing in novel embodiment, shows
So, described embodiment is a part of embodiment of the utility model, rather than whole embodiments.It is practical based on this
Embodiment in novel, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment is fallen within the protection scope of the utility model.Therefore, the implementation to the utility model provided in the accompanying drawings below
The detailed description of mode is not intended to limit the range of claimed invention, but is merely representative of the utility model
Selected embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative labor
Every other embodiment obtained under the premise of dynamic, fall within the protection scope of the utility model.
Shown in referring to Figures 1 and 2, a kind of exhaust valve rocker, including rocker arm body 1, wheel shaft 4 and casting die 5, rocker arm body 1
Including mounting portion 11, interconnecting piece 12 and forced section 13, interconnecting piece 12 is located at the middle part of mounting portion 11 and forced section 13, interconnecting piece 12
For the relatively thick intermediate thinner hourglass shape in both ends, interconnecting piece 12 is for connecting mounting portion 11 and forced section 13, mounting portion 11, connection
Portion 12 and forced section 13 are integral type, the production raw material that the interconnecting piece 12 of the relatively thick intermediate thinner hourglass shape in both ends uses compared with
It is few, cost is reduced, mounting hole 2 is offered on mounting portion 11, mounting hole 2 is for installing pin shaft, and then mounting portion 11 can be in pin
It is rotated on axis；
Referring to shown in Fig. 2 and Fig. 3, forced section 13 includes solid part 131 and hollow part 132, and hollow part 132 is provided with two altogether
A, hollow part 132 is located between two hollow parts 132 for installing idler wheel 3 and casting die 5, solid part 131, the hollow part of top
132 inside is equipped with idler wheel 3 by wheel shaft 4, and the upper end of idler wheel 3 protrudes from the upper surface of forced section 13, and cam can be direct
It is contacted with idler wheel 3, and then reduces the frictional force between cam and rocker arm body 1, reduce the abrasion of rocker arm body 1；
Shown in referring to FIG. 1, FIG. 2 and FIG. 3, casting die 5 includes positioning pin 51, briquetting 52 and foam 53, and the upper end of briquetting 52 is logical
The inside that positioning pin 51 is fixedly mounted on the hollow part 132 of lower section is crossed, the lower end surface of briquetting 52 is fixed with foam 53, positioning pin 51
It for bolt, and is lock state between positioning pin 51 and briquetting 52, briquetting 52 can be by the pressure of forced section 13, and then downwards
Piston is pressed, so that piston generates movement, briquetting 52 is up-narrow and down-wide form, and stability is enough, and the contact with piston
Area is larger, so that even piston stress.
Working principle: when using the present apparatus, the present apparatus is mounted on exhaust using the inside of pin shaft insertion mounting hole 2
The position of door so that the tilt angle of foam 53 is identical as the tilt angle of piston, at this time when the pointed end of cam press by
When idler wheel 3 in power portion 13 (being at this time rolling friction between idler wheel 3 and cam), forced section 13 can pull down briquetting 52,
And then foam 53 pulls down piston, so that piston moves.
