Description
Technical field
The utility model relates to automobile engine powder metallurgy parts molding technology thereof field, is specially a kind of valve guide bushing mould cooling adventitia tool.
background technology
Valve guide bushing is the guider of automotive engine valves, play the guiding role to valve, and makes the heat on valve stem pass to cylinder through valve guide bushing.Valve guide bushing, by cylindrical mould punch forming, needs to carry out water-cooled to mould outer surface in process of production, normally adopts water-cooled pond to carry out water-cooled, operational sequence is more, and cooling water can not fully flow, cause cooling effect poor, affect the end product quality of valve guide bushing.
Utility model content
The utility model provides a kind of cooling effect good valve guide bushing mould cooling adventitia tool.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Adventitia tool is used in a kind of valve guide bushing mould cooling, comprise the template offering bosh, this upper-lower position place, template both sides offers delivery port for being communicated with described bosh and water inlet respectively, described template upper end superposes successively and is provided with mould gland and surface plate, described bosh bottom, mould gland and surface plate correspondence position offers for the through hole through valve guide bushing mould.
Further, both sides, described surface plate top are provided with press strip.
Further, the through hole of described mould gland is stepped ramp type through hole, and this stepped ramp type through hole is for being fastened on the end face of described valve guide bushing mould.
Preferably, sealing strip is provided with between described template and mould gland.
From above technical scheme, the utility model outer mold is used to be placed on by valve guide bushing mould in the bosh in template, and positioned by the through hole that template bottom and mould gland are offered, cooling water is passed into continuously in bosh, the heat of valve guide bushing mould outer surface is taken away rapidly, increase cooling heat dissipation effect, improve the quality of products.

Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of preferred embodiment of the present utility model is described in detail.
As Fig. 1, shown in 2 and 3, the utility model adventitia tool comprises template 100 and superposes the mould gland 200 and the surface plate 300 that are arranged on this template upper end successively, the bosh 110 for placing valve guide bushing mould 400 is offered in described template, this bosh is by being opened in entering of template both sides, delivery port is communicated with outside, described bosh bottom, mould gland and surface plate corresponding valve guide bushing mould installed position offer the through hole for this mould, described bosh bottom becomes stepped ramp type structure with the via design of mould gland, wherein the stepped ramp type through hole 210 of mould gland is for being fastened on the end face of valve guide bushing mould.
Both sides, described surface plate 300 top are provided with press strip 500, this press strip by bolt by surface plate, be fixed connection between mould gland and mould.
As shown in Figure 3, the overall orthogonal design of described bosh 110, the length of the bosh degree of depth and valve guide bushing mould is suitable, bosh width allows mould to place, and there is certain gap for passing through cooling water, bosh length can design according to cooling effectiveness, and in the present embodiment, bosh once can be placed four moulds and cool.
Described template and mould gland junction are provided with sealing strip 600, and in the present embodiment, sealing bar is arranged on the bottom face of mould gland, and shown template offers the seal groove suitable with described sealing strip.
As shown in Figure 4, the cavity of a relative closure is formed between described bosh and mould gland, cooling water enters bosh from the water inlet 112 being positioned at template lower end, discharge from the delivery port 111 being positioned at template upper end after being full of cavity, cooling water flows in bosh, molding die surface is fully contacted with cooling water, reaches cooling effect.
The above embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
