Auto parts mainly include engine parts, transmission system parts, brake system parts, steering system parts, driving system parts and electrical instrument parts, etc. In the process of producing auto parts, die-casting technology is used to mass-produce auto parts. Die-casting is a metal casting process characterized by applying high pressure to the molten metal in the mold cavity.

[0003] During the die-casting process of some molds, it may be necessary to die-cast the steel pipe and the die-casting part into one piece. In the die-casting process, the steel pipe is generally placed directly on the die-casting mold. When the mold is injected and filled, the steel pipe may be offset due to the lack of limit, resulting in a large error in the die-casting molding and poor practicality. Utility Model Content

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 - Figure 6 This embodiment provides an integrated die for die-casting steel pipes and aluminum for automotive parts, including a limiting assembly 100. The limiting assembly 100 includes a die-casting area 101, a mold tube 102, and a clamping seam 103 arranged at the upper end of a workbench. A first limiting platform 101a for positioning the mold tube 102 is provided on the top of the die-casting area 101. The clamping seam 103 is opened on the first limiting platform 101a, and the mold tube 102 cooperates with the clamping seam 103; an ejection assembly 200 includes a second limiting platform 201 fixedly connected to the side of the workbench and a lifting component 202 connected to the workbench. The die-cast mold can be ejected through the lifting component 202.

[0031] It should be noted that the injected metal of the die-casting area 101 is aluminum alloy, the mold tube 102 is a steel tube, and the aluminum alloy is used to wrap the steel bar through the die-casting mold to form another product.

[0032] Furthermore, a plurality of protruding blocks 101a-1 are fixedly connected to the top of the first limiting platform 101a, and two adjacent protruding blocks 101a-1 are arranged in mirror symmetry.

[0033] It should be noted that two first limiting platforms 101 a are symmetrically arranged along the center line of the die-casting area 101 , and three protruding blocks 101 a - 1 are arranged on the top of the first limiting platforms 101 a .

[0034] Furthermore, a cavity 101a-1a is defined inside the protruding block 101a-1, and a slot 101a-1b is defined on one side of the first limiting platform 101a, and the slot 101a-1b is communicated with the cavity 101a-1a.

[0035] Furthermore, a positioning bead 101 a - 2 is slidably connected in the slot 101 a - 1 b , and the positioning bead 101 a - 2 cooperates with the mold tube 102 .

[0036] It should be noted that the positioning bead 101a-2 always slides in the slot 101a-1b and will not get stuck.

[0037] Furthermore, a spring 101a-2a is fixedly connected to the inner wall of the chamber 101a-1a, and one end of the positioning bead 101a-2 located in the chamber 101a-1a is fixedly connected to the spring 101a-2a.

[0038] Furthermore, a contact plate 102 a is fixedly connected to the circumferential surface of the mold tube 102 .

[0039] Furthermore, the locking seam 103 is provided below two positioning beads 101 a - 2 facing each other.

[0040] It should be noted that the concave surface of the clamping seam 103 is compatible with the mold tube 102 , which can provide a better limiting effect on the mold tube 102 .

[0041] Furthermore, a snap-fitting hole 201 a is provided on one side of the second limiting platform 201 , and the snap-fitting hole 201 a is snap-fitted to one end of the mold tube 102 .

[0042] It should be noted that the engagement of one end of the mold tube 102 with the engagement hole 201a can achieve a preliminary positioning effect on the mold tube 102, so that the positioning beads 101a-2 will not be offset when used to limit the position in the future, thereby increasing stability.

[0043] When in use, the mold tube 102 squeezes the positioning bead 101a-2 from the positioning bead 101a-2, so that the positioning bead 101a-2 slides in the slot 101a-1b, thereby squeezing the spring 101a-2a. When the mold tube 102 is engaged with the card joint 103, the spring 101a-2a is reset, thereby limiting the mold tube 102.

[0044] Example 2

[0045] Reference Figure 1 - Figure 6 Based on the previous embodiment, this embodiment provides an integrated mold for combining steel pipe and aluminum die-casting of automotive parts, wherein the lifting component 202 includes an electric push rod 202a and an ejection block 202b, the electric push rod 202a is fixedly connected to the workbench, and the ejection block 202b is fixedly connected to the output end of the electric push rod 202a.

[0046] In addition, a sliding groove is provided in the second limiting platform 201, and the ejection block 202b is slidably connected to the sliding groove.

[0047] Furthermore, the ejection block 202b cooperates with the contact plate 102a, and the circumferential surface of the positioning bead 101a-2 is a smooth curved surface.

[0048] It should be noted that Figure 1 - Figure 6 The structure in the figure is only used as a reference for mechanical transmission and is not a structural scale diagram of the final product.

[0049] When in use, first engage one end of the mold tube 102 with the engaging hole 201a for preliminary positioning, and then use the mold tube 102 to squeeze the positioning bead 101a-2 from the positioning bead 101a-2, so that the positioning bead 101a-2 slides in the slot 101a-1b, thereby squeezing the spring 101a-2a. When the mold tube 102 is engaged with the engaging seam 103, the spring 101a-2a is reset, thereby limiting the mold tube 102, preventing the mold tube from deflecting during the molding process, making it more stable, and effectively improving the product quality. The production efficiency is improved and the scrap rate of the product is reduced. At this time, the mold can be die-cast. After the die-casting is completed, the electric push rod 202a is turned on. The electric push rod 202a can drive the ejector block 202b to contact the contact plate 102a on the circumferential surface of the mold tube 102, thereby pushing the contact plate 102a to disengage the mold tube 102 from the engaging hole 201a, and by squeezing the positioning beads 101a-2, the mold tube 102 is disengaged from the engaging gap 103, and the die-casting of the steel pipe device and parts can be completed in a very short time, which has better practicality.
