Description

Technical Field

[0001] This utility model relates to the technical field of automotive volute casting gating system and its core-pulling mechanism, and in particular to a high-efficiency volute casting gating system and its core-pulling mechanism. Background Technology

[0002] With the increasing number of cars, people have higher and higher requirements for cars. The volute is an important component of the turbocharger. However, the existing volute has a low yield rate and the existing mold structure has a low demolding rate, which cannot meet the production needs and causes many inconveniences. Utility Model Content

[0003] In view of the deficiencies in the existing technology, this utility model provides a high-efficiency volute casting system and its core-pulling mechanism, with the aim of improving the yield of automotive volute castings.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A high-efficiency volute casting gating system and its core-pulling mechanism include: a main horizontal sprue; an venting channel, located above the main horizontal sprue and serving as a basic component of the gating system, which together form a good venting system to allow some of the gas in the molten metal to escape and prevent gas entrapment; slag pockets, located on the side of the venting channel, with multiple pockets provided to better remove and reduce slag and porosity within the casting; a volute casting located above the main horizontal sprue, through which the molten metal flows into the casting; a slider located on the side of the volute casting, used to perform core-pulling operations after casting is complete; standardized sliders to achieve cost savings and efficiency improvement; and a push rod located on the side of the volute casting, which, together with the slider, forms the core-pulling mechanism, used to perform core-pulling operations after casting is complete.

[0006] Preferably, the venting structure includes a venting channel and a slag trap. The venting channel is connected to the main runner, and during the molten metal filling process, it vents as much gas as possible from the mold cavity to reduce and prevent the generation of porosity defects in the die casting.

[0007] Preferably, the venting structure includes a venting channel and a slag bag. Multiple slag bags are disposed on the side of the venting channel to better remove and reduce slag and porosity within the casting.

[0008] Preferably, the core-pulling mechanism includes left-right core-pulling and top-bottom core-pulling mechanisms.

[0009] Preferably, the left and right core-pulling mechanism includes: slider 1, which is disposed on the left side of the volute casting; slider 2, which is disposed in front of the volute casting; slider 3, which is disposed behind the volute casting; and slider 4, which is disposed on the right side of the volute casting. Slider 1, slider 2, slider 3, and slider 4 constitute the left and right core-pulling mechanism. After injection molding is completed, the left and right core-pulling mechanisms start working simultaneously to start core pulling, thereby improving production efficiency.

[0010] Preferably, the upper and lower core-pulling mechanisms include an upper core-pulling mechanism and a lower core-pulling mechanism.

[0011] Preferably, the upper core-pulling mechanism includes: a push rod 1; a core-pulling cylinder 1 located on the side of the push rod 1; and a core-pulling cylinder 3 connected to the push rod 1, forming an upper core-pulling mechanism together with the push rod 1, and being driven by a slider to simultaneously pull the core.

[0012] Preferably, the lower core-pulling mechanism includes: a slider 5; a push rod 2 located on the side of the slider 5; a square guide post communicating with the slider 5; and a cylindrical sleeve communicating with the square guide post. The slider 5, the push rod 2, the cylindrical sleeve, and the square guide post constitute the lower core-pulling mechanism, and the slider 5 drives the core to be pulled simultaneously.

[0013] Compared with the prior art, based on the above technical solution, the beneficial effects of this utility model are as follows:

[0014] A high-efficiency volute casting gating system and its core-pulling mechanism are disclosed. This system incorporates a design with multiple slag pockets connected to venting channels, primarily aimed at improving casting quality. By effectively removing slag and porosity generated during the casting process, this improvement helps enhance the density and integrity of the casting, reducing product defects caused by impurities and porosity. This structural optimization solves the porosity problem commonly encountered in traditional casting processes, representing a significant technological advancement. Secondly, regarding the design of the core-pulling mechanism, the system combines left-right and top-bottom core-pulling mechanisms. Typically, in complex casting processes, there are multiple areas within the mold that are difficult to demold. Traditional core-pulling methods can be time-consuming and prone to damaging the mold. In this system, the core-pulling mechanism is achieved through the movement of a slider, providing efficient and synchronous core-pulling functionality. The slider-driven core-pulling method is particularly outstanding in automated operations, enabling rapid demolding, reducing production cycle time, and standardizing the slider to achieve cost savings and efficiency improvements. This design improves production efficiency, especially in high-volume production scenarios, significantly increasing factory capacity. Attached Figure Description
