Abstract

The invention provides a structure for improving the porosity of a key cylinder casting, by which little pores and qualified porosity inside a casted key cylinder is achieved so as to ensure the intensity of the key cylinder. The structure comprises a high-pressure liquid inlet, a diversion cone, a flow way, a pouring gate and a key cylinder cavity. The diversion cone is connected with the high-pressure liquid inlet and the flow way, wherein the diversion cone comprises a top conical port, a lower part communicated horizontal flow way part and other cavity parts from the horizontal flow way part to the bottom surface of the top conical port; the pouring gate comprises an upper pouring gate and a lower pouring gate; the upper pouring port and the lower pouring port are respectively connected with the upper part and the lower part of the key cylinder cavity; and the length of the central line from the key cylinder cavity to the diversion cone is shortened.

Description

Improve the structure of lock core foundry goods porosity
Technical field
The present invention relates to the field of the die casting of lock core, be specially the structure of improving lock core foundry goods porosity.
Background technology
Existing lock core casting mould, its lock core are after casting is accomplished, and the inner pore of lock core 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, and 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 be 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 of minute flow cone 1; Wherein, because the top of lock core die cavity 4 material is thin, the bottom material is thick, during one of which cast gate 3; Material gets in the lock core die cavity 4 from top to bottom; And portion forms whirlpool within it, and air goes out not go, and causes the thick place of material, bottom to form pore.
Summary of the invention
The invention provides the structure of improving lock core foundry goods porosity, the pore of the lock core inside after it makes casting accomplish is few, porosity is qualified, thereby guarantees the intensity of lock core.
Improve the structure of lock core foundry goods porosity; It comprises the highly pressurised liquid charging aperture, divides flow cone, runner, cast gate, lock core die cavity; The said highly pressurised liquid charging aperture of flow cone conducting in said minute, runner; It is characterized in that: said minute flow cone comprises that top tapered mouth, bottom are communicated with all the other cavity parts of horizontal run part, horizontal run part to top tapered mouth bottom surface; Said cast gate comprises top-pour mouth, the submarine gate, and said upward cast gate, the submarine gate connect top, the bottom of said lock core die cavity respectively, and said lock core die cavity is to the contraction in length that divides the flow cone center line.
It is further characterized in that:
Said runner comprises horizontal component runner, vertical component runner, and the said submarine gate is communicated with said horizontal component runner through the vertical component runner.
After adopting structure of the present invention; 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 accomplish 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 invention.
The specific embodiment
See Fig. 2; The present invention includes the highly pressurised liquid charging aperture and (belong 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 all the other cavity parts 6 of horizontal run part 5, horizontal run part 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 a 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 through vertical component 10 runners.

Claims (2)

1. improve the structure of lock core foundry goods porosity; It comprises the highly pressurised liquid charging aperture, divides flow cone, runner, cast gate, lock core die cavity; The said highly pressurised liquid charging aperture of flow cone conducting in said minute, runner; It is characterized in that: said minute flow cone comprises that top tapered mouth, bottom are communicated with all the other cavity parts of horizontal run part, horizontal run part to top tapered mouth bottom surface; Said cast gate comprises top-pour mouth, the submarine gate, and said upward cast gate, the submarine gate connect top, the bottom of said lock core die cavity respectively, and said lock core die cavity is to the contraction in length that divides the flow cone center line.
