Abstract
The utility model discloses a die for a chilled cast iron cam shaft. The die for the chilled cast iron cam shaft comprises a template, a sprue cup, a spure and an ingate, and further comprises more than two cam shaft cavities which are formed by precoated sand, the cam shaft cavities are vertically arranged on the right side of the spure through the ingate in a parallel mode, the cam shaft cavities, the sprue cup, the spure and the ingate are all fastened with the template in a thread mode, a first filter screen is installed at a connecting position of the sprue cup and the spure, and second filter screens are respectively installed at connecting positions between the ingate and each cam shaft cavity. The die for the chilled cast iron cam shaft has the advantages of being compact in arrangement of structure, good in interchangeability, good in skimming and filtering capacity, and the like.
Description
Technical field
The utility model relates generally to the camshaft mould, is specially a kind of Chilled Cast Iron Camshaft mould.
Background technology
At present, known mould for the chill casting casing camshaft generally adopts the manufacturing of monoblock type metal material, in prior art, this mould all adopts two camshaft die cavities mostly, makes casting process yield always not high, and this mould is owing to adopting monoblock type, namely process with machining center is disposable above plank at one, thereby interchangeability is not high, especially after die wear, just can only again make a new mould, waste lot of materials, made production cost higher.The utility model is called on and is being addressed the above problem.
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 the Chilled Cast Iron Camshaft mould that a kind of compact conformation, interchangeability are strong, pushing off the slag filtering ability is good is provided.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of Chilled Cast Iron Camshaft mould, comprise template, cup, sprue, ingate, described mould also includes the plural at least camshaft die cavity by the precoated sand moulding, described camshaft die cavity is arranged in parallel within described sprue right side up and down by described ingate, described camshaft die cavity, cup, sprue, ingate all adopt screw thread to carry out fastening with described template, described cup and described sprue junction are equipped with the first screen pack, and the junction of described ingate and described each camshaft die cavity all is equipped with the second screen pack.
Preferably, be provided with three camshaft die cavities in described mould.
Preferably, the shape of described the first screen pack and the second screen pack all adopts a bowl type.
Mold for cam shaft of the present utility model, the mesh of described the first screen pack and the second screen pack is the square of 2 * 2mm.
Further, described ingate diameter is greater than described camshaft die cavity diameter.
Further, be provided with several alignment pins on described template.
Further, described template edge also is provided with several lock housing screws.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model is mould three types by conventional cam shaft with mould two type advantageous embodiment of mould, make whole mould have advantages of compact conformation, improve casting process yield widely, reduced the placer iron ratio, saved the process operations time, thereby reduced production cost, improved production efficiency, be connected by screw threads for fastening due between the utility model convexity wheel shaft die cavity and template, thereby in practical operation, factory can select to arrange camshaft die cavity number according to actual needs.
2, in the utility model by all adopting screw thread to carry out fastening with described template camshaft die cavity, cup, sprue, ingate, make Mould Machining simple, easy for installation, be convenient to part to be dismantled replacement after die wear, overcome the poor shortcoming of existing monolithic mold interchangeability.
3, in the utility model between cup and sprue, be provided with screen pack between ingate and each camshaft die cavity, in casting process, the mobility molten iron of melting is injected cup, flow into again the camshaft die cavity by above-mentioned the first screen pack, the second screen pack, because screen pack can be with the dregs filtering of size greater than the screen pack mesh size, therefore adopt two-layer screen pack, make the casting slag inclusion fraction defective of foundry goods will be reduced to 5%-8%, greatly improved the quality of foundry goods after the moulding.
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.
Fig. 1 is the structural representation of the present embodiment;
Reference numeral: 1-template, 2-cup, 3-sprue, 4-ingate, 5-camshaft die cavity, 601-the first screen pack, 602-the second screen pack, 7-alignment pin, 8-lock housing screw.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
In conjunction with a kind of Chilled Cast Iron Camshaft mould shown in Figure 1, comprise template 1, cup 2, sprue 3, ingate 4, this mould also includes the plural at least camshaft die cavity 5 by the precoated sand moulding, its camshaft die cavity 5 is arranged in parallel within sprue 3 right sides up and down by ingate 4, in conjunction with Fig. 1 as can be known, be provided with three camshaft die cavities 5 described in the present embodiment in mold for cam shaft, make whole the mould features compact structure, improved widely casting process yield, reduced the placer iron ratio, saved the technological operation time.
Simultaneously, in the present embodiment, camshaft die cavity 5, cup 2, sprue 3, ingate 4 all adopt screw thread to carry out fastening with template 1, overcome the poor shortcoming of existing monolithic mold interchangeability, make whole Mould Machining simple to operate, easy for installation, in case when in use concentrated wear occurring, this part can be dismantled replacement, save production cost.
In the present embodiment, to adopt screw thread to carry out fastening due to camshaft die cavity 5 and template 1, thereby in practical operation, factory can select to arrange camshaft die cavity 5 numbers according to actual needs.
In addition, its cup 2 is equipped with the first screen pack 601 with sprue 3 junctions, ingate 4 all is equipped with the second screen pack 602 with the junction of each camshaft die cavity 5, preferably, the shape of this first screen pack 601 and the second screen pack 602 all adopts a bowl type, the mesh of two screen pack is the square of 2 * 2mm, certainly, mesh also can adopt the shapes such as circle, prismatic, and the wire that these two screen packs are 0.2mm by diameter is made, the fusing point of this fusing point wiry molten iron used during greater than casting.In casting process, the mobility molten iron of melting is injected cup, flow into again camshaft die cavity 5 by above-mentioned the first screen pack 601, the second screen pack 602, because screen pack can be with the dregs filtering of size greater than the screen pack mesh size, therefore adopt two-layer screen pack, make the casting slag inclusion fraction defective of foundry goods will be reduced to 5%-8%, greatly improved the quality of foundry goods after the moulding.
