Abstract
The utility model discloses a glue feeding structure of a die-casting die. The glue feeding structure comprises a flowing way, a glue feeding port and a cavity and is characterized in that a cavity body of the glue feeding port is arc-shaped, the arc-shaped cavity body of the glue feeding port is bent towards the direction of the bottom of the cavity. By improving a glue feeding point of the die-casting die and a flowing way structure, a liquid working material first enters the bottom of the die cavity and air in the cavity is gradually discharged out, thereby effectively solving the problem that a die-casting workpiece easily produce air bubbles and improving the die-casting quality of the workpiece.
Description
Technical field
The utility model relates to the machining casting field, specifically is that a kind of novel die casting advances plastic structure.
Background technology
Die casting is a kind of method of casting liquid forging, a kind of technology of on the die casting die forging machine of special use, accomplishing.Its basic craft course is: molten metal elder generation's low speed or high-speed casting fill in the die cavity of type progressive die tool; Mould has movable cavity surface; It is along with the cooling procedure pressurization of molten metal is forged; Both eliminated the shrinkage porosity defect of contraction cavity of blank, and also made the interior tissue of blank reach the broken crystal grain of forging attitude, the comprehensive mechanical performance of blank is significantly improved.But die casting also has some common problems, and like cold line, slight crack, pore etc., the pore major part that forms in the die casting derives from the gas of pressing in the die cavity of chamber; Reduce the pore amount in the die casting; Just fully exhaust lets gas from die cavity, successfully released by molten metal, though prior art is provided with air discharge duct in mould; But receive the flow influence of factors such as speed, flow channel shape of molten metal, its pore problem still can not be well solved.
Summary of the invention
The technical purpose of the utility model is to solve the problems of the prior art, provides a kind of die casting that can effectively overcome air bubble problem in the die casting workpiece to advance plastic structure.
The technical scheme of the utility model is:
A kind of die casting advances plastic structure, comprises runner, glue-feeder and die cavity, it is characterized in that: the cavity of said glue-feeder is curved, and the arc cavity of said glue-feeder is crooked towards the bottom direction of said die cavity.After liquid labor and materials are flowed out from glue-feeder,, at first flow into the bottom of die cavity, upwards fill full die cavity from the bottom gradually, the air in the die cavity is discharged gradually according to its inertia that flows.
Further technical scheme comprises:
As preferably, intersect the tangent line of the tie point of glue-feeder cavity end face and die cavity and the bottom surface of said die cavity.
Said runner comprises sprue and runner; The runner cavity that is connected with said glue-feeder is made as ramped shaped; The liquid of avoiding the flip-flop because of the glue-feeder shape to cause refluxes; The arc cavity of runner and said glue-feeder will be connected smoothly, and the smoothness of runner cavity also is the key factor that has influence on the die casting quality.
The plastic structure that advances of the utility model also is provided with the air discharge duct that is connected with said die cavity.
The utility model structural design is simple, but efficiently solves in the press casting procedure, and liquid labor and materials are involved in air and the halfway problem of die cavity exhaust easily in die cavity, improved the quality and the yields of die casting, and be easy to promote the use of.
Description of drawings
Fig. 1 is provided with the main TV structure sketch map that the utility model advances the die casting equipment of plastic structure;
Fig. 2 is provided with the plan structure sketch map that the utility model advances the die casting equipment of plastic structure;
Fig. 3 is the plan structure sketch map of the utility model;
Fig. 4 is the main TV structure sketch map of the utility model.
The specific embodiment
For technical scheme and the technical purpose of illustrating the utility model, the utility model is done further introduction below in conjunction with the accompanying drawing and the specific embodiment.
Like Fig. 1, shown in Figure 2; A kind ofly be provided with the die casting equipment that the utility model die casting advances plastic structure, comprise devices such as cope match-plate pattern, lower bolster, guide pillar, it advances plastic structure and comprises sprue 2, runner 12 and die cavity 13; Said runner 12 is communicated with said die cavity 13 through glue-feeder 11; The cavity of said runner 12 is ramped shaped, and runner 12 is connected smoothly with the arc cavity of said glue-feeder 13, and the cavity of said glue-feeder 11 is curved; As shown in Figure 4; The arc cavity of said glue-feeder 11 is crooked towards the bottom direction of said die cavity 13, also can make the bottom surface of tangent line and said die cavity 13 of tie point of arc cavity end face and die cavity 13 of glue-feeder 11 crossing further, to reduce the air that the liquid labor and materials possibly be involved in as far as possible.The top of said die cavity 13 is communicated with air discharge duct.
After beginning casting, liquid labor and materials get into from sprue 2, get into the runner 12 of both sides then, and liquid labor and materials flow to the bottom of die cavity 13 along the radian of its cavity glue-feeder 12 in, upwards overflow then, with gas through air discharge duct upwards discharge gradually.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
