Embodiment Construction

[0010] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

[0011] as attached figure 1 shown. The runner structure of the die-casting molding mold for the sports skateboard bridge designed in this embodiment can form 12 products at one time, including three layers arranged along the length direction of the main channel, and each layer includes four distributed along the outer periphery of the main channel, a total of 12 models cavity.

[0012] The skateboard bridge molded by the mold of this embodiment is an irregularly shaped aluminum alloy piece with a plane and two symmetrically distributed arcuate surfaces on the opposite side of the plane. Correspondingly, there are two curved inner walls and one plane inner wall on the inner wall of the mold.

[0013] Specifically, the runner structure of the die-casting molding mold for the spor...

Abstract

The invention discloses a sports skateboard bridge die-cast molding mold runner structure. A skateboard bridge is an aluminum alloy piece, and comprises a main runner communicating with a stub bar; multiple branch runners are arranged at the outer periphery of the main runner; an arc side wall of a molding cavity is provided with an inner gate communicating with the branch runners; multiple slag ladles are arranged on the outer wall of the molding cavity; and four sets of slag ladles are provided, and consist of two sets positioned at two ends of the plane inner wall of the molding cavity andtwo sets positioned on the other arc side wall. The structure can mold multiple products at the same time to achieve high molding efficiency; and through arrangement of specifications, numbers and positions of the runners and the slag ladles, products are not easy to generate such defects as air holes inside, the strength of each part of the products is more uniform and higher, and the service life is longer.

Description

technical field [0001] The invention relates to the improvement of die-casting technology of aluminum alloy parts. Background technique [0002] The skateboard bridge is a key component that connects the wheels and the skateboard plates in the skateboard. It is made of aluminum alloy and has high requirements for strength. In the prior art, the die-casting process is generally used, and the die-casting efficiency is low, and the strength is difficult to improve. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a runner structure of a die-casting molding mold for a sports skateboard skateboard bridge with high die-casting efficiency and greater product strength. [0004] The present invention scheme is as follows: [0005] A runner structure of a die-casting mold for a sports skateboard bridge. The skateboard bridge is an aluminum alloy part, including a main channel connected to the material head. A plurality of...
