Abstract

The utility model relates to a mould of a cylinder cover of a vehicle engine of fine coasting ball graphite in a casting state, wherein, a sliver convex bottom mould 1 is sheathed with a mould bottom plate 2 which is provided with a left mould block 3, a right mould block 5, a front mould block 7 and a back mould block 8. Top racks of the left mould block 3 and the right mould block 5 are provided with convex top mould blocks 4 and the middle part is provided with a movable circular metal core 6 and a sand core 9. Compared with the prior art, the utility model has the characteristics of small occupied land, long service life, convenient assembly and fine casting requirements, time saving, labor saving and low cost, etc. The utility model is helpful for the scaled production.

Description

Smart casting as cast condition spheroidal graphite cylinder cover of automobile engine mould

The utility model relates to casting mould, particularly smart casting as cast condition spheroidal graphite cylinder cover of automobile engine mould.

Use the sand casting cylinder head, exist that floor space is wide, time-consuming, poor working environment, be unfavorable for deficiencies such as large-scale production.In the patent disclosure of number of patent application 90105953 " a kind of moulding technology with compound water-glass sand for casting base of enamal bathtub " still have above-mentioned deficiency.

The purpose of this utility model provides a kind of precision casting mould, and is durable, the essence casting as cast condition spheroidal graphite cylinder cover of automobile engine mould of saving of work and time.

The purpose of this utility model is to realize like this, the bed die of its rectangular convex is with baffle plate, be mounted with left module, right module and front module, back module on the baffle plate, left module and right module are pushed up the mould jacking block of the convex of putting on the shelf, and there are movable circular metal core and core in the centre.The utility model adopts several its inwalls of big module consistent with the cylinder head outer shape, and the outside is linearly, and the smart casting cylinder head that is easy to use fast is combined into mould simultaneously again.

Compared with prior art, take up an area of and lack, long service life is convenient to combination and smart casting needs, saving of work and time, and expense is low, helps characteristics such as large-scale production.

Below in conjunction with accompanying drawing the utility model is further specified.

Accompanying drawing is the utility model sectional structure schematic diagram.

Among the figure: module 9-core behind the metal-cored 7-front module of the 1-bed die 2-baffle plate 3-left side module 4-mould right module 6-of the jacking block 5-8-

As shown in drawings, bed die 1 is with baffle plate 2, and left module 3, right module 5 and front module 7, back module 8 are arranged on the baffle plate, and frame has mould jacking block 4 between left module 3 and right module 5, and the centre has metal-cored 6 and core 9.

Claims

1. an essence is cast as cast condition spheroidal graphite cylinder cover of automobile engine mould, the bed die (1) that it is characterized in that rectangular convex is with baffle plate (2), be mounted with left module (3), right module (5) and front module (7), back module (8) on the baffle plate (2), left side module (3) and right module (5) are pushed up the mould jacking block (4) of the convex of putting on the shelf, and there are movable circular metal core (6) and core (9) in the centre.
