Abstract

The utility model relates to a cylinder cover metal casting mould with exhausting structure, which consists of an upper die, a left and right side die and a bottom die; the left side die is combined by a left side upper die and a left side lower die, and has a plurality of exhausting grooves formed on the joining surfaces of the left side upper die and the left side lower die; the right side die is combined by a right side upper die and a right side lower die, and has a plurality of exhausting grooves formed on the joining surfaces of the right side upper die and the right side lower die. The utility model completely eliminates the abuses in prior arts; by exhausting the gas in the mould cavity smoothly, the utility model effectively eliminates the probability of under-casting of cylinder cover, improves cylinder head product qualified rate and enterprise economic benefit.

Description

Cylinder head metal casting mould with exhaust structure

Technical field

The utility model relates to a kind of casting mould of gasoline engine cylinder lid, particularly a kind of cylinder head metal casting mould with exhaust structure.

Background technology

Cylinder head is the important component part of engine, the cam mechanism that is used for supporting engine, have structures such as entering and exhaust channel, water-cooling channel, combustion chamber above, complex-shaped, corresponding its complicate fabrication process that determined, cylinder head is generally the metal pattern gravitational casting now, and according to shape of cylinder head, metal die is divided into bed die, left side mould, right side mould, patrix.Bed die is positioned at the mould below, forms the location of head combustion chamber and jacket core, airway core.Left side mould and right side mould form the appearance of cylinder head, respectively are an integral module.This version of this mould is because the top of two side form piece die cavities is that molten metal is filled the position at last, exhaust is not smooth, position, cylinder head upper edge is occupied by gas, causes shape of cylinder head imperfect, forms to owe to cast defective, the lighter reprocesses, weight person scraps, and causes the qualification rate of product low, not only influences output, delays manufacturing schedule, but also the increase production cost reduces economic benefit of enterprises.

The utility model content

The utility model owes to cast defective at the cylinder head that above-mentioned reason produces, a kind of new mould with exhaust structure is provided, although change little to mould, can guarantee again that simultaneously the gas of die cavity discharges smoothly, effectively reduce cylinder head and produce and owe to cast the probability of defective, improve the qualification rate that cylinder head is produced, reduce production costs, guarantee manufacturing schedule, improve the cost performance and the market competitiveness, and then improve economic benefit of enterprises.

The utility model is achieved through the following technical solutions:

Be made up of patrix, left and right sides side form and bed die, the left side mould through combining, and has some exhaust trench by left side upper module and left side lower module on the surface of docking of left side upper module and left side lower module; Described right side mould be by right side upper module and right side lower module through combining, and on right side upper module and surface that the right side lower module docks, have some exhaust trench.

Described exhaust trench is on the lower surface of left and right sides upper module, and longitudinally uniform setting is along the end face that laterally extends to the right and left always.

The cross section of described exhaust trench is selected from a kind of in isosceles triangle, equilateral triangle, right angled triangle and the difform groove.

The wide of described exhaust trench is 0.5mm, is 0.5mm deeply.

The utility model has the advantages of as follows:

The utility model compared with prior art, because left and right sides side form is divided into two-part knockdown structure up and down, and the technical measures of on the inner surface of left and right sides upper module, setting up some exhaust trench, and eliminated the drawback that prior art exists fully through evidence.Because the gas of die cavity is discharged smoothly, effectively eliminate cylinder head and produce the probability of owing to cast, improve the qualification rate and the economic benefit of enterprises of cylinder head product.

Among the figure: 1, patrix, 2, the right side upper module, 3, the right side lower module, 4, bed die, 5, the left side upper module, 6, the left side lower module, 7, exhaust trench.

The specific embodiment

Embodiment

Content of the present utility model is described in detail in conjunction with the accompanying drawings by embodiment.Be sectional structure schematic diagram of the present utility model as shown in Figure 1, comprise bed die 4, left side upper module 5 is loaded on the bed die 4 after left side lower module 6 usefulness shop bolts, bolt combination, right side upper module 2 is loaded on the bed die 4 after right side lower module 3 usefulness shop bolts, bolt combination, above patrix 1 is loaded on.Below the wherein said left and right sides

upper module

5,2, promptly with the interface of the

lower module

6,3 that docks separately on the longitudinally uniform exhaust trench 7 that has, described exhaust trench is along laterally extend to the end face of the right and left shown in Fig. 2,3 always.Its cross section is selected from a kind of in isosceles triangle, equilateral triangle, right angled triangle and the irregular shape groove.Preferred isosceles triangle, it is wide to be 0.5mm, is 0.5mm deeply.
