Problems solved by technology

Forging processing cannot realize one-time molding, and it also needs to cooperate with the corresponding processing technology to combine multiple parts into one. This method of processing has complicated process flow, high cost and low production efficiency.
The die-casting process in the prior art can realize one-time molding, but in the conventional die-casting process, the mold cavity is not exhausted in time when the step of injecting into the mold is implemented, so that some air remains in the mold cavity, and this kind of air enters the product As a result, there are defects in the product, insufficient product density and poor smoothness, until it affects the subsequent turning and surface coloring treatment

Embodiment Construction

[0007] See attached figure 1 As shown, the present invention is a manufacturing method of die-casting processing fishing gear, which mainly includes the steps of mold closing, soup feeding, injection into the mold, cooling, mold opening and sampling, turning and surface treatment in succession. A vacuuming process is added synchronously to the implementation process of the steps.

[0008] The two halves of the mold are closed to form a hollow mold cavity. The soup is delivered to the heat preservation furnace through the corresponding spoon to transport the aluminum alloy material that has been dissolved at high temperature in advance, and then injected into the mold. The dissolved aluminum alloy material enters the mold through the material tube. Molding in the cavity, and at this time, the vacuum device connected to the mold is started synchronously to evacuate, and the residual air in the cavity is drawn out of the mold in time, so that a vacuum state is formed in the cavit...

Abstract

A vacuum die casting technology for making the fishing tool includes closing die set, vacuumizing, pouring molten material, cooling, opening die set, machining and processing system. Its advantages are high casting speed, and high quality of product.

Description

Technical field: [0001] The invention relates to the technical field of fishing gear products, in particular to a manufacturing method of die-casting processed fishing gear. Background technique: [0002] Existing processing fishing gear, as the processing method of products such as fishing reel mainly contains forging processing and die-casting processing. Forging processing cannot realize one-time molding, and it also needs to cooperate with the corresponding processing technology to combine multiple parts into one body. This method of processing has complicated process flow, high cost, and low production efficiency. The die-casting process of the prior art can realize one-time molding, but in the conventional die-casting process, the cavity is not exhausted in time when the step of injecting into the mold is implemented, so that some air remains in the cavity, and this kind of air enters the product As a result, there are flaws in the product, insufficient product densit...
