Description

Technical Field

[0001] This utility model relates to the field of die-casting parts production and processing technology, specifically to a tooling for milling the sprue of die-casting parts. Background Technology

[0002] A pizza oven is a baking device primarily used to bake prepared dough, shaping it into a pizza. A pizza oven mainly consists of the oven body, oven door, chimney, and other components. The dough inlet of the oven body typically uses a die-cast aluminum front nose as an edge protection component, and its structure is as follows... Figure 7 As shown. Previously, the nose die-cast aluminum part was an irregular arc shape with high appearance requirements, resulting in numerous sprue marks requiring grinding after die-casting. Because the front nose die-cast aluminum part has high hardness and toughness, manual grinding is not only time-consuming but also difficult to achieve a smooth surface, easily leading to deformation and product scrap. In summary, manual sprue grinding is time-consuming, yields poor results, is costly, and produces inconsistent quality. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tooling for milling the gate of die-cast parts, so that it can be applied to the front nose die-cast aluminum parts (hereinafter referred to as castings) and can be used with a CNC milling machine to perform milling processing on the die-cast aluminum parts.

All the first limiting members, second limiting members and third limiting members are arranged in an elliptical shape.

[0007] A top limiting assembly, comprising a plurality of movable pressing members disposed around the periphery of the bottom limiting assembly; and...

[0008] A control switch, which is connected to the movable top pressure component.

[0009] Preferably, the inner edge of the first limiting member has an upwardly protruding first limiting flange for engaging the inner surface of the casting.

[0010] Preferably, the second limiting member has a second limiting protrusion extending upward from the middle for insertion into the casting.

[0011] Preferably, the outer edge of the third limiting member has an upwardly protruding third limiting flange for engaging the outer side of the casting.

[0014] Preferably, the pressure rod includes a connecting block at one end connected to the drive source, and a pressure block for pressing down the casting is detachably provided at the other end of the connecting block.

[0015] Preferably, the shape of the bottom of the pressure block is adapted to the shape of the top of the casting.

Detailed Implementation

[0028] To enhance understanding of this utility model, it will be further described in detail below with reference to embodiments and accompanying drawings. This utility model can be implemented in the following ways:

[0029] Reference Figure 1-7 A milling fixture for removing sprue marks from die-cast parts includes a base 1, a bottom limiting component 2, a top limiting component 3, and a control switch (not shown in the figure). The base 1 is detachably mounted on a machine tool; the bottom limiting component 2 and the top limiting component 3 are mounted on the base 1. In this embodiment, the bottom limiting component 2 and the top limiting component 3 are used to fix the casting from all directions, which can significantly improve the grinding accuracy of the sprue marks on the casting 4.

[0030] To prevent horizontal swaying of the casting 4 during processing, the bottom limiting assembly 2 includes symmetrically arranged first limiting members 21. The inner edge of the first limiting member 21 has an upwardly protruding first limiting flange 211 for engaging the inner side of the casting 4, and the outer edge of the first limiting member 21 has a first limiting step 212 for engaging the outer side of the casting 4. Symmetrically arranged on both sides of the first limiting member 21 are second limiting members 22. The middle of each second limiting member 22 has an upwardly protruding second limiting protrusion 221 for insertion into the casting 4. The side shape of the second limiting protrusion 221 conforms to the internal shape of the casting 4, allowing it to completely fit inside the casting 4 and reducing horizontal swaying. A third limiting member 23 is provided on the opposite side of the second limiting member 22 relative to the first limiting member 21. The outer edge of the third limiting member 23 protrudes upward to form a third limiting flange 231 for engaging the outer surface of the casting 4. A third limiting groove 232 is provided on the side of the third limiting flange 231. All the first limiting members 21, second limiting members 22, and third limiting members 23 are arranged in an elliptical shape. This embodiment is a dual-station tooling, which can improve processing efficiency. Specifically, with the centerline parallel to the long side as the central axis, the first limiting member 21, two second limiting members 22, and two third limiting members 23 located on the same side of the central axis are arranged in an arc shape, jointly fixing a casting 4. In this design, the first limiting member 21 fixes the inner side of the casting 4, the third limiting member 23 fixes the outer ends of the casting 4, and the second limiting member 22 fixes the interior of the casting 4, thus restricting the casting 4 in all directions, preventing horizontal wobbling during operation, and significantly improving processing precision.

[0031] To prevent vertical swaying of the casting 4 during processing, the top limiting component 3 includes several movable pressing components 31 disposed around the bottom limiting component 2; in this embodiment, eight movable pressing components 31 are provided, four for each processing station. Specifically, each movable pressing component 31 includes a pressing rod 311 and a drive source 312 for controlling the lifting and rotation of the pressing rod 311. The pressing rod 311 includes a connecting block 3111 connected at one end to the drive source 312, and a lower pressing block 3112 for pressing down the casting 4 is detachably disposed at the other end of the connecting block 3111. The shape of the bottom of the lower pressing block 3112 is adapted to the shape of the top of the casting 4 to better press down the casting 4. In this embodiment, the bottom of the lower pressing block 3112 is a horizontal plane. The drive source 312 includes a rotating shaft 3121 connected to the connecting block 3111 of the pressing rod 311 and a single-axis rotary cylinder 3122 for controlling the lifting and rotation of the rotating shaft 3121. The single-axis rotary cylinder 3122 is equipped with a quick-connect air hose 3123 that connects to a control switch. The control switch is connected to the movable top pressing member 31, specifically, it is connected to the drive source 312. The control switch is controlled by CNC programming, using programming code to control the rotation of the single-axis rotary cylinder 3122 and the clamping and releasing of the casting 4.

[0032] Working principle: Two castings 4 are placed on the fixture, so that they are just secured to the first limiting piece 21, the second limiting piece 22, and the third limiting piece 23. The control switch is activated, and the single-axis rotary cylinder 3122 controls the rotating shaft 3121 to rotate the pressure rod 311, so that the lower pressure block 3112 of the pressure rod 311 is above the casting 4. Then, the single-axis rotary cylinder 3122 controls the rotating shaft 3121 to lower the pressure rod 311 and press it against the casting 4. After the sprue milling operation of the casting 4 is completed, the single-axis rotary cylinder 3122 controls the rotating shaft 3121 to raise and rotate the pressure rod 311 to release the casting 4, allowing the operator to remove the casting 4 and completing the operation. During this process, the rotation direction of the pressure rod to release the casting is as follows: Figure 2 As shown by the arrow, the direction of the lever's lifting and lowering is as follows: Figure 3 As indicated by the arrow.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
