Abstract
The utility model discloses a motor bicycle chilled cast iron camshaft mould which comprises a template, a shell type locating pin, a camshaft mould cavity and a pouring system, wherein the camshaft mould cavity is arranged on the template, the pouring system is connected with one end of the camshaft mould cavity, and the pouring system is tightly connected with the template through a bolt. A chilling block fixture arranged inside the camshaft mould cavity is composed of two movable blocks which are arranged symmetrically, and the movable blocks are in movable and detachable connection with the camshaft mould cavity. The motor bicycle chilled cast iron camshaft mould can accurately locate the chilling block inside the camshaft mould cavity, reduces the design of a chilling block core mark, brings convenience to mould manufacture, improves product size accuracy, reduces the phenomena of overlap and burr, and improves casting quality of camshafts.
Description
Technical field
The utility model relates generally to mould, is specially a kind of motorcycle Chilled Cast Iron Camshaft mould.
Background technology
the chill casting casing camshaft is to place at the peach nose part of cam the purpose that suitable contoured chill reaches local Quench, therefore the spoken parts in traditional operas that forms enough degree of depth at the nose position replaces the martensite of quenching, and require chill that enough hardness is arranged, the General Requirements chill degree of depth is greater than 3mm, the not low HRC45-47 of peach point hardness, tissue to basic circle is followed successively by spoken parts in traditional operas to the cam section from the peach point, the fiber crops mouth, the ash mouth, thereby guarantee that the nose working surface has enough wearabilities, excellent toughness and processing characteristics, but known ground, the difficult point of Quench camshaft is to make the shape of chill, size and camshaft die cavity obtain best agreeing with, the existing chill technical elements of laying, after the mould such as being generally and making shell mould, chill is lowered in shell mould, and then enter cast and produce, and that chill in use can wear and tear is larger, and after chill is lowered in die cavity, can't locate preferably, can form larger space with die cavity, be easy to produce overlap and burr, so that the camshaft castability can not get ensureing, the phenomenon of scarce and crackle easily appears collapsing.
For above-mentioned deficiency, the utility model is called on and is being solved these technical problems.
The utility model content
The purpose of this utility model is the problem of mentioning in the above-mentioned background technology in order to solve, and a kind of motorcycle Chilled Cast Iron Camshaft mould of chill good positioning effect is provided.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of motorcycle Chilled Cast Iron Camshaft mould, comprise template, shell mould alignment pin, camshaft die cavity and running gate system, described camshaft die cavity is arranged on described template, described running gate system is connected with described camshaft die cavity one end, described running gate system and described template are connected by screw fastening, be provided with the chill fixture in described camshaft die cavity, described chill fixture is comprised of two symmetrically arranged movable blocks, and described movable block and described camshaft die cavity are flexibly connected detachable.
Preferably, be provided with at least two chill fixtures in described camshaft die cavity.
Further, described running gate system is comprised of cup, sprue, ingate, and the described sprue left and right sides is symmetrically distributed with eight type camshaft die cavities, and described camshaft die cavity is communicated with described sprue by described ingate.
Further, be provided with the first screen pack between described cup and described sprue, be provided with the second screen pack between described ingate and described camshaft die cavity.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model chill locating effect is better.the utility model is provided with the chill fixture in the camshaft die cavity, this chill fixture is comprised of two symmetrically arranged movable blocks, described movable block and camshaft die cavity are flexibly connected detachable, the historical facts or anecdotes border can be according to regulate the width of chill fixture with the width size of chill, make the chill fixture that frozen iron blocks is clamped, chill position, accurate location, reasonable in design, reduced in the traditional operation design to the chill core print, be convenient to the mould manufacturing, and improved the product size precision, when the mould mould assembly, this chill can the whole mold cavity of fastening embedding in, reduced the mould assembly operation easier, improved the mould assembly effect, the phenomenon of burr when having reduced the camshaft casting, improved the camshaft castability.
2, the utility model is simple in structure, easy to use.The movable block of the utility model chill fixture and described camshaft die cavity are flexibly connected detachable, because the chill fixture of a sleeve forming is applicable to the frozen iron blocks of different model, usage range is wide, is easy to promotion and implementation, has good economic benefit.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, during the below will describe embodiment, the accompanying drawing of required use is done to introduce simply, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
