Description

Technical Field

[0001] This utility model belongs to the field of die casting mold technology, specifically relating to a device for removing runners from a transmission housing. Background Technology

[0002] In the manufacturing process of transmission housing castings, sprues are often required at the injection points of molten metal to allow the molten metal to flow smoothly into the mold cavity. After the transmission housing casting cools and solidifies, the sprues need to be removed to form the final shape of the transmission housing. Traditionally, sprue removal is done manually, where workers use hammering tools to separate the sprues from the casting after it has cooled and solidified. This method has several drawbacks: the casting and sprues are heavy, resulting in high labor intensity for workers during handling and removal; the casting needs to be handled multiple times during removal, increasing the risk of impact; and manual removal is inefficient and poses health hazards due to dust. To improve automation, reduce worker labor intensity, and improve the working environment, a fully automated sprue removal system is needed. However, there is a lack of suitable automated sprue removal devices for transmission housings, necessitating improvement. Utility Model Content

The lower surface of the clamping plate near the casting protrudes to form a protrusion.

[0008] Furthermore, the bracket includes two support plates arranged opposite each other, and a rotating shaft connecting the two support plates, with the clamping pressure plate sleeved on the rotating shaft.

[0009] Furthermore, the base is also provided with a plurality of positioning pins, each positioning pin including a positioning pin base and a positioning rod vertically inserted into the positioning pin base, wherein the upper side wall of the positioning rod can abut against the inner hole of the casting.

The pressing column includes an integrally connected connecting plate and a column body vertically disposed on the bottom surface of the connecting plate. An impact head is disposed at one end of the column body near the receiving box.

[0011] Furthermore, the receiving box is an open-top box.

[0012] Furthermore, the base is provided with a plurality of first mounting holes and a plurality of second mounting holes, wherein the drive cylinder is inserted into the first mounting hole and the positioning pin is inserted into the second mounting hole.

[0054] The working principle of this utility model is as follows: The lower template 1 and upper template 5 of the trimming machine are opened. A robotic arm places the casting 6 with the sprue 7 onto the clamping device 2, which is then clamped by the hydraulic clamp assembly 22 and positioning pin 23. The robotic arm then withdraws from the working area. The upper template 5 of the trimming machine drives the removal device 4 downwards, applying pressure to the sprue 7, causing it to break. The broken sprue 7 falls into the receiving box 3. The robotic arm then removes the casting 6, completing the sprue 7 removal process.
