[0002] The die-casting mold for the bearing cover base is a specialized casting equipment used to form the bearing cover base, a core component of engines. The mold uses its internally precision-machined cavity structure to give the molten alloy the final product shape. Its design usually needs to take into account the filling mode of the molten metal, the solidification shrinkage characteristics, and the subsequent demolding process to ensure that it can efficiently and stably produce thick-walled box-type castings with complex geometric features and meet strict dimensional tolerances and internal quality requirements. It is a key process equipment on the production lines of automobile, ship and heavy machinery engines.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0016] Specific implementation examples are given below.
[0017] Reference Figure 1 - Figure 5 One embodiment of this utility model provides: a die-casting mold for a tile cover base, comprising: Rear mold base plate 1; The rear mold frame 2 is supported above the rear mold frame base plate 1 by square iron 4; The front mold frame 3 is positioned opposite to the rear mold frame 2; The front mold core 9 is fixed to the front mold frame 3; The rear mold core 10 is fixed to the rear mold frame 2 and together with the front mold core 9, forms the molding cavity of the product. Main channel 5, formed on the front mold base 3, is used to introduce molten metal into the cavity; The sliding mechanism includes a sliding cylinder 6 and a sliding body 12 driven by the sliding cylinder 6; The ejection mechanism includes an ejector pin guide post 7 and an ejector pin body 8 guided by the ejector pin guide post 7; The positioning mechanism includes a positioning guide post 11 and a positioning guide hole 13 that mates with the positioning guide post 11; The mold includes a fixed mold operating side 14 and a fixed mold non-operating side 15. The positioning guide post 11 on the front mold frame 3 and the positioning guide hole 13 on the rear mold frame are used to achieve the alignment of the front and rear molds. The front mold core 9 fixed on the front mold frame 3 and the rear mold core 10 fixed on the rear mold frame 2 together form the molding cavity of the product. Molten metal is injected into the cavity through the main channel 5 formed on the front mold frame 3. When the mold is opened, the sliding cylinder 6 fixed on the side of the rear mold frame 2 first drives the sliding body 12 to complete the lateral core pulling. Then, the ejector guide post 7 fixed on the bottom plate 1 of the rear mold frame guides the ejector body 8 to perform the ejection movement to demold the molded product. The rear mold frame 2 is supported above the bottom plate 1 of the rear mold frame by the square iron 4 to provide the necessary movement space for the ejection mechanism. The two sides of the mold are respectively set as the fixed mold operating side 14 with hydraulic and electrical interfaces and the fixed mold non-operating side 15 for fixing, which promotes the efficient and accurate die casting of the tile cover base parts.
[0018] Reference Figure 2 and Figure 4 The sliding cylinder 6 is fixedly installed on the side of the rear mold frame 2, and the sliding body 12 is slidably set on the side of the rear mold core 10 for forming the lateral features of the product. The sliding cylinder 6 is fixedly installed on the side of the rear mold frame 2 and drives the sliding body 12 to slide on the side of the rear mold core 10 to form the undercut features such as holes and grooves on the side of the product, thereby realizing the lateral core pulling action before or during mold opening and ensuring that the die-cast product is successfully demolded.
[0019] Reference Figure 3 The ejector pin guide post 7 is fixed to the rear mold base plate 1, and the ejector pin body 8 is movably disposed in the rear mold core 10. Under the guidance of the ejector pin guide post 7, the molded product is ejected from the rear mold core 10. The ejector pin guide post 7 is fixed to the rear mold base plate 1, and the ejector pin body 8 is movably disposed in the rear mold core 10. Under the guidance of the ejector pin guide post 7, the ejector pin body 8 moves smoothly, thereby reliably ejecting the molded product from the cavity of the rear mold core 10 after mold opening, thus completing demolding.
[0020] Reference Figure 3 The positioning guide post 11 is set on the front mold base 3, and the positioning guide hole 13 is set on the rear mold base 2. The positioning guide post 11 is inserted into the positioning guide hole 13. The positioning guide post 11 is set on the front mold base 3, and the positioning guide hole 13 is correspondingly set on the rear mold base 2. When the mold is closed, the positioning guide post 11 is inserted into the positioning guide hole 13 to promote the alignment of the front and rear mold bases, effectively reduce the positional deviation during the mold closing process, ensure the closure of the molding cavity formed by the front mold core 9 and the rear mold core 10, and ensure the dimensional accuracy and appearance quality of the die-cast product.
[0021] Reference Figure 5The fixed mold operating side 14 is equipped with hydraulic and electrical interfaces for controlling the sliding cylinder 6 and the ejection mechanism, while the fixed mold non-operating side 15 is the fixed side of the mold. The fixed mold operating side 14 is equipped with hydraulic or electrical interfaces for controlling the sliding cylinder 6 and the ejection mechanism, providing power source and control signals for the moving parts of the mold, while the fixed mold non-operating side 15 is firmly connected to the die-casting machine as the fixed side of the mold, ensuring the stability and operability of the mold operation.
[0022] Working principle: When the mold is closed, the positioning guide post 11 is inserted into the positioning guide hole 13 to realize the alignment of the front mold base 3 and the rear mold base 2, so that the front mold core 9 and the rear mold core 10 are closed to form a molding cavity. The molten metal is injected into the cavity through the main channel 5. After holding pressure and cooling, the front mold base 3 and the rear mold base 2 are separated. The sliding cylinder 6 drives the sliding body 12 to complete the side core pulling. Then, the ejector plate drives the ejector body 8 to move forward under the guidance of the ejector guide post 7, and ejects the casting from the rear mold core 10. After the ejection is completed, the ejector body 8 returns to its original position under the guidance of the ejector guide post 7, and the mold closes again to prepare for the next die casting cycle.
[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
