Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of removing sand core heads of cylinder covers, in particular to a device for removing sand core heads of cast cylinder covers. Background Art
[0002] Currently, in the automotive engine aluminum alloy cylinder head casting industry, after the cylinder head is produced using molten aluminum, molds, sand cores, and other related raw materials and process equipment, the cast cylinder head is generally picked up by a mechanical pick-up arm and placed on a conveyor belt. The (hoisting) operator uses a tool (aluminum hammer) to knock out the cylinder head's riser sand core heads and airway sand core heads, and then inspects the cylinder head for external defects and registers product information. This tool-knocking method is inconvenient for the hoisting operator. When knocking out the cylinder head's riser sand core heads and airway sand core heads, the product is still in the cast state, posing a risk of burns. There is also the possibility of related core heads splashing. Heatstroke is more likely to occur in hot weather, affecting operator safety and increasing their workload, indirectly slowing down the production cycle and affecting cylinder head production efficiency. Utility Model Content
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide an automatic device for removing the sand core head of a cast cylinder head, which is convenient to operate and will not cause burns.
[0004] The purpose of the utility model is achieved through the following technical solutions: an automatic sand core head removal device for a cast cylinder head comprises a bracket and a support column, the bracket is mounted on the support column, and coring head mounting plates are mounted on the left and right sides and front and rear sides of the bracket, riser sand core head removal blocks are mounted on the coring head mounting plates located on the left and right sides of the bracket, airway sand core head removal blocks are mounted on the coring head mounting plates located on the front and rear sides of the bracket, a crossbeam is mounted on the airway sand core head removal block, and a waste sand bucket is mounted under the bracket.
[0005] The coring head mounting plate has a U-shaped groove, which is connected to the airway sand core head removal block or the riser sand core head removal block by bolts in the U-shaped groove. The position of the airway sand core head removal block or the riser sand core head removal block can be adjusted accordingly according to the different specifications of the cast cylinder head by moving the bolts in the U-shaped groove to adapt to the use of various cylinder heads. The bracket is cross-shaped, and its hollowed-out part is connected to the waste sand bucket to facilitate the core head waste sand to fall into the waste sand frame. Protective covers are installed on the periphery of the bracket and on the outside of the coring head mounting plate to prevent the core head from splashing during automatic coring. A base is installed at the bottom of the support column to ensure the overall stability of the device.
[0006] With this new structure, the cast cylinder head is positioned above the bracket and protective cover and slowly pressed downward. The downward pressure automatically removes the riser core head, the airway core head removal block, and the crossbeam, reducing operator workload and preventing burns and core head splashing. The device is easy to use, automatic, and quick, with low manufacturing costs and a practical structure, ensuring operator safety and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 This is a schematic diagram of the installation and application structure of the utility model. DETAILED DESCRIPTION
[0008] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.
[0009] Reference Figure 1 It can be seen that the automatic sand core head removal device of the cast cylinder head of the present invention includes a bracket 1 and a support column 10. The bracket 1 is installed on the support column 10. Coring head mounting plates 2 (four in total) are installed on the left and right sides and front and rear sides of the bracket 1. Riser sand core head removal blocks 4 are installed on the coring head mounting plates 2 located on the left and right sides of the bracket. Airway sand core head removal blocks 6 are installed on the coring head mounting plates 2 located on the front and rear sides of the bracket. A crossbeam 7 (whose length is slightly larger than that of the airway sand core head removal block) is installed on the airway sand core head removal block 6. A waste sand bucket 8 (with a bucket-shaped outlet) is installed under the bracket 1.
[0010] The coring head mounting plate features a U-shaped groove 5, which connects to the airway core removal block 6 or the riser core removal block 4 via bolts 3. The position of the airway core removal block or riser core removal block can be adjusted to accommodate various cylinder head specifications by moving the bolts within the U-shaped groove. The bracket 1 is cross-shaped, with a hollowed-out portion connected to a waste sand hopper 8, facilitating the drop of waste sand from the riser and airway cores into the waste sand basket below. A square protective shield 9 is installed around the perimeter of the bracket 1 and on the outside of the coring head mounting plate 2 to prevent splashing of the riser and airway cores during automatic coring. A base 11 (connected to the ground) is mounted at the bottom of the support column 10 to ensure the overall stability of the device.
[0011] The upper part of the present invention is the robot picking arm. After the robot picking arm clamps the cast cylinder head, it slowly presses down on the bracket 1 and the protective cover 9. The riser sand core head removal block 4 automatically removes the riser sand core head on the cast cylinder head, and the airway sand core head removal block 6 and the crossbeam 7 automatically remove the airway sand core head on the cast cylinder head.
