Description

A kind of automobile aluminum piston press mould
Technical field
The present invention relates to a kind of mould applications, especially a kind of automobile aluminum piston press mould.
Background technology
, it is necessary to consider quality of the piston base part in die molding process, existing mould in auto parts and components production Have when producing automobile aluminum piston due to mould molding in the presence of very big vibrations, cause inner void many, crystal density is low, influence Service life.
The content of the invention
The present invention provides a kind of piston that can produce high-quality, to solve the shortcoming in above-mentioned background technology.
Technical problem solved by the invention is realized using following technical scheme:
A kind of automobile aluminum piston press mould, upper die plate, pushing block, briquetting, material cylinder, extruding outlet;Under described upper die plate Side is fixed with spring, and described spring connection briquetting, described pushing block is located at briquetting top and is fixed on upper die plate lower surface;Institute Piston is fixedly connected below the briquetting stated, also including guide pad, described described guide pad is arranged on material cylinder top, described Guide pad in have a guiding cavity, described piston is located at and is oriented in cavity, described guidings cavity also with the inner chamber company of material cylinder It is logical, extruded in the inner chamber that described piston enters into material cylinder from guiding cavity;The inner chamber of described material cylinder is additionally provided with charging Passage, described feeding-passage is also associated with putty block.
The guiding cavity top of described guide pad is bell-mouthed targeting port.
Upper die plate is descending, and pushing block is contacted into briquetting first, and briquetting promotes descent of piston, aluminium water to enter pan feeding from feeding-passage again The inner chamber of cylinder, putty block blocks feeding-passage;Piston is extruded from the inner chamber for being oriented to cavity and entering into material cylinder, from squeezing out Mouth extrusion is simultaneously cooled down rapidly, obtains extrusion forming piston, and then upper die plate is up, and pushing block departs from briquetting first, then in spring Briquetting and piston are slowly extracted out under pulling force.
A kind of automobile aluminum piston press mould that the present invention is provided, in process of production, by pushing block and briquetting two Individual module design, is reduced to being shaken during piston press, and the bad generation hole of product improves the quality of product, and extending makes Use the life-span.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
Now it is described further by embodiment.
As shown in figure 1, a kind of automobile aluminum piston press mould, upper die plate 1, pushing block 4, briquetting 3, material cylinder 6, squeeze out Mouth 7;The described lower section of upper die plate 1 is fixed with spring 2, and the described connection briquetting 3 of spring 2, described pushing block 4 is located on briquetting 3 Side is simultaneously fixed on the lower surface of upper die plate 1;The lower section of described briquetting 3 is fixedly connected piston 10, described also including guide pad 5 Described guide pad 5 is arranged on the top of material cylinder 6, there is guiding cavity in described guide pad 5, and described piston 10 is empty positioned at being oriented to In chamber, described guiding cavity also with the inner space of material cylinder 6, described piston 10 entered into material cylinder 6 from cavity is oriented to Extruded in chamber;The inner chamber of described material cylinder 6 is additionally provided with feeding-passage 8, and described feeding-passage 8 is also associated with putty block 9.
The guiding cavity top of described guide pad 5 is bell-mouthed targeting port.
Upper die plate 1 is descending, and pushing block 4 is contacted into briquetting 3 first, and briquetting 3 promotes piston 10 descending again, and aluminium water is from feeding-passage 8 inner chambers for entering pan feeding cylinder 6, putty block 9 blocks feeding-passage 8;Carried out in the inner chamber that piston 10 enters into material cylinder 6 from guiding cavity Extruding, cools down from the extrusion of extruding outlet 7 and rapidly, obtains extrusion forming piston, and then upper die plate 1 is up, and pushing block 4 departs from first Briquetting 3, then slowly extracts briquetting 3 and piston 10 out under the pulling force of spring 2.
