Abstract
The utility model discloses a die-casting die for a cylindrical casting. A sprue is formed in one end of a pouring gate. Hole walls are arranged at two sides of the pouring gate respectively. The hole walls penetrate through a cavity. Air discharging ports are formed in the cavity. The sectional area of the air discharging port which is close to the pouring gate is larger than the sectional area of the air discharging port which is far from the pouring gate. The air discharging ports are connected with air discharging pipelines. Air which is brought to the cavity by solution is discharged from the air discharging ports, air holes are not easily produced in a product, and therefore percent of pass is increased. The solution flows into the cavity from the hole walls so that impact of the solution on the cavity can be reduced, and the service life of the cavity can be prolonged.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of die casting of making the cylindrical shape foundry goods.
Background technology
Compression casting is called for short die casting, is that a kind of to pour molten alloy liquid the pressure of die casting into indoor, with the die cavity of high speed filling mould, and alloy solution is solidified under pressure and forms the casting method of foundry goods.The main feature of die casting is high pressure and high speed, but common pressure casting method is subjected to the restriction of some product special shapes.For example when making the cylindrical shape foundry goods, solution along the product outline around, the flow velocity of solution is inequality, the first half flow velocity is fast, the latter half flow velocity is slow.The first half flow to exhaust place, and earlier confluxing with the latter half solution after the entrance shutoff, exhaust outlet is sealed by solution, and air row does not go out and will form pore, the qualification rate reduction of product on the product; And solution is understood direct impact mold cavity, reduces the life-span of die cavity.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of die casting for the cylindrical shape foundry goods, and its objective is can be with air scavenge, and reduces solution to the impact of die cavity.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of die casting for the cylindrical shape foundry goods comprises running channel and the die cavity that is connected on the described running channel, and described running channel one end offers cast gate; Described die cavity offers exhaust outlet, and described running channel both sides are respectively equipped with hole wall, and described hole wall runs through described die cavity.
Preferably, described exhaust outlet connects discharge duct.
Preferably, the sectional area of the described exhaust outlet of nearly running channel is greater than the sectional area of the described exhaust outlet of running channel far away.
By above technical scheme, a kind of die casting for the cylindrical shape foundry goods described in the utility model.Alloy solution enters running channel from cast gate, advances to water by the hole wall that is arranged on the running channel both sides, progressively fills to the running channel place after directly filling cavity bottom.Gas is discharged from exhaust outlet, and product is about to fill when finishing, and undischarged gas concentrates on nearly running channel place in the die cavity, so the exhaust outlet sectional area at nearly running channel place is bigger, assurance gas is all discharged, and guarantees casting quality, improves product percent of pass.Flow of solution is advanced to water through hole wall, makes solution less to the impact of die cavity, prolongs the service life of die cavity.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the schematic diagram of the disclosed a kind of die casting for the cylindrical shape foundry goods of the utility model embodiment.
The represented corresponding component title of numeral among the figure:
1. cast gate 2. running channels 3. die cavities 4. discharge ducts 5. hole walls
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of die casting for the cylindrical shape foundry goods, and its structural principle is that die cavity is set up steam vent, and running channel is extended to die cavity inside, reduces solution to the impact of die cavity.
Embodiment:
Embodiment provides a kind of die casting for the cylindrical shape foundry goods, and as shown in Figure 1, running channel 2 both sides are respectively equipped with hole wall 5, and hole wall 5 runs through die cavity 3, and an end of running channel 2 offers cast gate 1; Die cavity 3 offers exhaust outlet (not indicating among the figure), and the sectional area of the exhaust outlet of nearly running channel 2 is greater than the sectional area of the exhaust outlet of running channel 2 far away, and described exhaust outlet connects discharge duct 4.
A kind of die casting for the cylindrical shape foundry goods of the present utility model.Alloy solution enters running channel 2 from cast gate 1, advances to water through the hole wall 5 that is arranged on running channel 2 both sides, progressively fills to running channel 2 places after directly filling die cavity 3 bottoms, reduces solution like this to the impact of die cavity 3, prolongs the service life of die cavity 3.The gas that enters die cavity 3 along with solution is discharged by discharge duct 4 from exhaust outlet, product is about to fill when finishing, undischarged gas concentrates on nearly running channel 2 places in the die cavity 3, the exhaust outlet sectional area at nearly running channel 2 places is bigger, all discharge to guarantee gas, guarantee not contain pore on the product, improve product percent of pass.
Above-mentioned explanation to disclosed a kind of die casting embodiment for the cylindrical shape foundry goods makes this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
