Abstract
The utility model provides a structure for improving the porosity of lock cylinder castings, which causes a cast lock cylinder to have less internal air holes and qualified porosity, so as to ensure the strength of the lock cylinder. The structure comprises a high-pressure liquid feed port, a sprue spreader, a runner, a sprue and a lock cylinder cavity, wherein the sprue spreader communicates the high-pressure liquid feed port with the runner. The structure is characterized in that the sprue spreader comprises a top conical opening, a lower communicated horizontal runner part, and rest cavity parts from the horizontal runner part to the bottom surface of the top conical opening; the sprue comprises an upper sprue and a lower sprue which are respectively connected with the upper part and the lower part of the lock cylinder cavity, and the length from the lock cylinder cavity to the center line of the sprue spreader is shortened.
Description
Technical field
The utility model relates to the field of the die casting of lock core, is specially a kind of structure of improving lock core foundry goods porosity.
Background technology
Existing lock core casting mould, its lock core are after casting is finished, and the pore of lock core inside is many, make the weak strength of lock core, trace it to its cause be because: the air in the length of runner and the runner has caused porosity defective too much.
Existing lock core foundry goods runner cast structure is seen Fig. 1, it comprises branch flow cone 1, runner 2, cast gate 3, wherein, the corresponding bar runner of lock core die cavity 42, a cast gate 3, dividing flow cone 1 is the taper closed cavity of 2 horizontal planes from the highly pressurised liquid charging aperture to runner, lock core die cavity 4 is long to the length l of the center line that divides flow cone 1, wherein, because the top of lock core die cavity 4 material is thin, the bottom material is thick, during one cast gate 3, material enters in the lock core die cavity 4 from top to bottom, and portion forms whirlpool within it, air goes out not go, and causes the thick place of material, bottom to form pore.
Summary of the invention
The utility model provides a kind of structure of improving lock core foundry goods porosity, and the pore of the lock core inside after it makes casting finish is few, porosity is qualified, thereby guarantees the intensity of lock core.
A kind of structure of improving lock core foundry goods porosity, it comprises the highly pressurised liquid charging aperture, divides flow cone, runner, cast gate, lock core die cavity, the described highly pressurised liquid charging aperture of flow cone conducting in described minute, runner, it is characterized in that: described minute flow cone comprises that top tapered mouth, bottom are communicated with horizontal run part, horizontal run part all the other cavity parts to top tapered mouth bottom surface, described cast gate comprises top-pour mouth, the submarine gate, described upward cast gate, the submarine gate connect top, the bottom of described lock core die cavity respectively, and described lock core die cavity is to the contraction in length that divides the flow cone center line.
It is further characterized in that:
Described runner comprises horizontal component runner, vertical component runner, and the described submarine gate is communicated with described horizontal component runner by the vertical component runner.
After adopting structure of the present utility model, during charging, the smaller volume of the branch flow cone of required formation, and then the air in its volume reduces, the lock core die cavity directly causes the shortening of runner to the contraction in length that divides the flow cone center line, and the shortening of runner makes the air of runner cavity reduce; In addition, the submarine gate connects the bottom of lock core die cavity respectively, and feed opening directly pours the material thickness portion, can not produce too much pore; In sum, the pore of the lock core inside after this structure makes casting finish is few, porosity is qualified, thereby guarantees the intensity of lock core.。
Description of drawings
Fig. 1 is existing lock core foundry goods runner cast structure three-dimensional stereogram;
Fig. 2 is a structural representation 3 dimensional drawing of the present utility model.
The specific embodiment
See Fig. 2, the utility model comprises that the highly pressurised liquid charging aperture (belongs to existing mature structure, do not draw among the figure), divide flow cone 1, runner 2, cast gate, lock core die cavity 3, divide flow cone 1 conducting highly pressurised liquid charging aperture, runner 2, divide flow cone to comprise that top tapered mouth 4, bottom are communicated with horizontal run part 5, horizontal run part all the other cavity parts 6 to top tapered mouth bottom surface, cast gate comprises top-pour mouth 7, the submarine gate 8, last cast gate 7, the submarine gate 8 connect top, the bottom of lock core die cavity 3 respectively, and lock core die cavity 3 shortens to the length L of dividing flow cone 1 center line.
Runner 2 comprises horizontal component runner 9, vertical component runner 10, and the submarine gate 8 is communicated with horizontal component runner 9 by vertical component 10 runners.
Claims (2)
1. structure of improving lock core foundry goods porosity, it comprises the highly pressurised liquid charging aperture, divides flow cone, runner, cast gate, lock core die cavity, the described highly pressurised liquid charging aperture of flow cone conducting in described minute, runner, it is characterized in that: described minute flow cone comprises that top tapered mouth, bottom are communicated with horizontal run part, horizontal run part all the other cavity parts to top tapered mouth bottom surface, described cast gate comprises top-pour mouth, the submarine gate, described upward cast gate, the submarine gate connect top, the bottom of described lock core die cavity respectively, and described lock core die cavity is to the contraction in length that divides the flow cone center line.
