Description

Technical Field

[0001] The utility model belongs to the technical field of spinning molds, and more specifically, relates to a spinning split mold. Background Art

[0002] The automotive wheel hub is a crucial component of the vehicle. It not only supports the wheel's weight and transmits power, but also significantly impacts the vehicle's handling, stability, and comfort. Spinning wheels offer superior mechanical properties and internal structure compared to low-pressure casting, leading to their widespread use.

[0003] Wheel spinning dies primarily consist of three parts: the core mold, the pressure plate, and the ejector. However, for similar wheel models whose rim structures share a partially identical axial shape, differing only in the A-side styling, developing a complete set of spinning dies for each wheel set would require numerous mold changes during production, a cumbersome operation. Utility Model Content

[0004] The purpose of the utility model is to provide a spinning split mold, which aims to solve the problem that for similar models of wheels with the same or similar rim structures but different A-side shapes, if a complete set of spinning molds is developed for each set of wheels, the number of spinning molds is large and they need to be replaced as a whole during the production process, which is very cumbersome to operate.

[0005] To achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: providing a spinning split mold, comprising a core mold, a pressure plate and a plurality of ejectors, wherein the upper end of the core mold is provided with an assembly groove, the upper ends of the plurality of ejectors are provided with A-surface molding surfaces of different shapes, and the plurality of ejectors are selectively installed in the assembly groove in a detachable manner;

[0006] The outer circumference of the core mold is detachably mounted with an adaptor, the outer circumference of the core mold forms an initial molding surface of the rim, and the adaptor and the core mold have a first use state and a second use state;

[0007] In a first use state, the adapting functional component blocks a portion of the initial rim forming process so that the unblocked portion of the initial rim forming process forms a rim forming surface;

[0008] In the second usage state, the outer peripheral surface of the adapting functional part is axially overlapped with the initial molding surface of the rim, so that the outer peripheral surface of the adapting functional part and the initial molding surface of the rim jointly form a rim molding surface.

[0009] In one possible implementation, the adaptation functional part includes an adaptation auxiliary ring, which is sleeved on the lower part of the core mold. The adaptation auxiliary ring blocks the lower area of ​​the initial molding surface of the rim, and the upper area of ​​the initial molding surface of the rim that is not blocked forms the rim molding surface.

[0010] In a possible implementation, the bottom of the core mold is integrally formed with an integral mounting portion, the adapter auxiliary ring is connected to the upper end of the integral mounting portion, and the outer circumference of the adapter auxiliary ring is arranged in a conformal manner with the outer circumferential surface of the integral mounting portion.

[0011] In a possible implementation, the adapter auxiliary ring is connected to the upper end of the integrated mounting portion from top to bottom by a plurality of circumferentially arranged connecting bolts.

[0012] In a possible implementation, the adapting functional part includes an adapting split ring, which is located at the bottom of the core mold. The outer peripheral surface of the adapting split ring is overlapped with the outer peripheral surface of the adapting functional part to jointly constitute the rim molding surface.

[0013] In a possible implementation, a split mounting portion is integrally formed on the lower portion of the adapting split ring, and the adapting split ring is connected to the bottom of the core mold.

[0014] In a possible implementation, the adaptor split ring is connected to the bottom of the core mold from bottom to top through a plurality of circumferentially arranged connecting bolts.

[0015] In one possible implementation, a positioning protrusion is provided in the middle of the lower end surface of the ejector, a positioning groove adapted to the positioning protrusion is provided in the middle of the groove bottom of the assembly groove, and a guide inclined surface is formed on the outer periphery of the ejector, and the ejector is adapted to be installed in the assembly groove through the guide inclined surface.

[0016] In a possible implementation, the ejector is connected to the assembly groove by a plurality of circumferential connecting bolts that penetrate the ejector longitudinally.

[0017] The beneficial effect of the spinning split mold provided by the present invention is that: compared with the existing technology, the upper end of the ejector has an A-surface molding surface, and the shapes of the A-surface molding surfaces of several ejectors are different, and the A-surface molding surface of each ejector matches the A-surface structure of a model hub. In the first use state, the adapting functional part blocks part of the initial molding of the rim so that the unblocked part of the initial molding of the rim forms the rim molding surface; in the second use state, the outer peripheral surface of the adapting functional part axially overlaps the initial molding surface of the rim so that the outer peripheral surface of the adapting functional part and the initial molding surface of the rim together form the rim molding surface. When producing similar models of hubs with the same partial shape of the rim structure but different A-surface shapes, there is no need to replace the pressure plate and the core mold. Only the corresponding ejector needs to be replaced to mold the A-surface structure of the required hub, and then the first use state or the second use state of the adapting functional part is selected to achieve the desired hub rim structure. The utility model provides a spinning split mold that can solve the problem of similar model wheels with the same or similar rim structures but different A-side shapes. Production needs can be met by simply replacing the ejector and the adapter functional parts. The operation is very convenient and the production efficiency is improved.
