Description
Technical Field
The utility model relates to the technical field of casting, in particular to a pouring device for a dynamic balance part.
Background
When the punch presses at high speed, the higher the speed, the larger the inertia force of the slide block, and the larger the deformation of the machine body. This affects the accuracy of the die, aggravates the wear of the die, and requires the addition of a dynamic balancing device to overcome the inertial force of the slide.
The dynamic balance part is applied to a dynamic balance device of a high-speed punch.
Just because the dynamic balance part is the key spare part of high speed punch press, when traditional gating system was shaping dynamic balance part, problems such as cinder hole, batch seam appear easily in the part surface. Improvements have now been made to the casting apparatus in view of the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a pouring device for a dynamic balance part, which optimizes a pouring gate assembly, is additionally provided with a riser for slag collection and feeding and improves the product quality of a casting.
The technical scheme adopted by the utility model for solving the technical problems is as follows: a casting device for dynamic balance parts comprises:
a horizontal runner for guiding molten metal into the ingate;
the inner pouring gate is communicated with the cavity of the casting;
the blind riser is arranged on the cross gate and is connected with the cross gate and the ingate; and
the blind riser is internally provided with a cavity for storing liquid metal, and the cavity part is positioned below the cross gate.
Compared with the prior art, the utility model has the advantage that after the metal liquid enters the cross pouring channel, the metal liquid firstly enters the cavity of the casting through the blind riser and then enters the cavity of the casting through the ingate. The structure setting of blind riser can avoid the foundry goods to appear shrinkage cavity and shrinkage porosity defect. The cavity in the hidden riser can effectively store liquid metal, supply metal when the casting is formed, and prevent the casting from shrinkage cavity and shrinkage porosity. The inner cavity part of the blind riser is positioned below the cross gate, liquid metal can fall down when being guided into the inner cavity of the blind riser, and the blind riser has a buffering function, so that the speed of the liquid metal entering the cavity is reduced, and the liquid metal is beneficial to discharging air and impurities in the cavity. The blind riser of the utility model plays a role in collecting slag and collects sand slag in the casting process.
Further preferred embodiments of the present invention: the cross pouring gate is provided with a blind riser which is basically shaped as a cylinder, and the axial direction of the blind riser is perpendicular to the cross pouring gate. Specifically, the blind riser is arranged along the vertical line direction of the horizontal plane.
Furthermore, the cavity comprises a buffer part with a hemispherical structure, the buffer part is positioned at the bottom of the cavity, the buffer part is positioned below the cross pouring gate, and the buffer part is positioned below the ingate. Namely, the liquid metal led into the cross gate falls to the buffer part of the cavity under the action of gravity after entering the blind riser, and then enters the cavity through the ingate after passing through the buffer action of the buffer part. The buffer part is arranged, so that the speed of the liquid metal entering the cavity can be effectively reduced, and the air and impurities in the cavity can be discharged.
Furthermore, the upper wall surface of the cavity is a convex hemispherical surface. If the flow rate of the liquid metal entering the blind riser is relatively fast, there is a potential for the liquid metal to impinge upwardly along the wall of the blind riser. At the moment, the upper wall surface of the cavity of the hemispherical structure can well buffer the impact of liquid metal, and the upward impact force received by the cavity is decomposed to the lateral direction, so that the overlarge impact force received by the top surface of the blind riser is avoided.
Furthermore, the top surface of the blind riser is provided with a groove, and the groove is in a conical structure.
Furthermore, the basic shape of the cavity is a circular truncated cone with the diameter gradually increasing from top to bottom.
Further, the width of the ingate in the longitudinal section of the ingate perpendicular to the flowing direction of the liquid metal is smaller than the diameter of the blind riser. Specifically, the longitudinal section is perpendicular to the flow direction of the liquid metal in the ingate.
Specifically, on the longitudinal section of the ingate, the width of the ingate is smaller than the height of the ingate. That is, the ingate has a long and narrow structure, specifically, the height is taken as the vertical direction of the horizontal plane, and the width is taken as the length direction of the horizontal runner, so that the height of the ingate is larger than the width of the ingate. Because the width of the inner pouring channel is narrow, a part of residues with larger particles can be filtered, so that the residues can be left in the hidden riser and cannot enter the cavity.
Furthermore, the length of the horizontal plane in the vertical direction is taken as the height, and the height of the ingate is larger than that of the cross gate. In an initial state, the height of the liquid metal led into the cavity through the cross gate is not higher than that of the cross gate, the height of the ingate is higher than that of the cross gate, and then air in the cavity can be discharged to a blind riser through the ingate, so that the quality of the interior of a product is improved.
Furthermore, the inner pouring gate is connected with a patch section, and the patch section is positioned on one side of the inner pouring gate close to the cavity. Specifically, the patch section is connected with the cavity, and the patch section is located on the periphery of the wall surface of the cavity.
Furthermore, the longitudinal section area of the patching section is larger than that of the ingate, and metal is supplied to the patching section when the casting is formed, so that the casting is prevented from shrinkage cavity and shrinkage porosity.
Furthermore, the device comprises two sections of cross runners, the cross runners are matched with the structure of the cavity, and the cross runners surround the periphery of the cavity.
Furthermore, the two sections of cross runners are positioned on the same horizontal plane, and a space is reserved between the two sections of ring runners.
Furthermore, a plurality of ingates are arranged on the transverse pouring channel, and the ingates are connected with the cavities. Through the arrangement of the cross pouring channel and the inner pouring channel, molten iron can uniformly flow into the casting mold from multiple directions of the cavity, and a casting with good quality can be obtained.
Furthermore, the utility model also comprises a straight pouring channel, wherein the straight pouring channel is arranged along the vertical direction of the horizontal plane and is connected with the two cross pouring channels. Specifically, the sprue is disposed perpendicular to the runner.
Furthermore, a connecting section is arranged below the sprue, the sprue is connected with the cross gate through the connecting section, the connecting section is communicated with the cross gate, the connecting section is located below the cross gate, and the top surface of the connecting section is connected with the bottom surface of the cross gate. The structure arrangement enables the liquid metal entering the cross runners from the sprue to enter the two cross runners at a constant speed.
Furthermore, the caliber of the sprue is gradually reduced from top to bottom.
