Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold for an air guide cover. Background Art

[0002] An injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and molten plastic into the mold cavity under high pressure by an injection molding machine, and obtaining a molded product after cooling and solidification.

[0003] Existing air guide hood injection molds are mostly cooled by natural cooling after injection molding. This cooling method takes a long time and often leads to adhesion between the mold and the casting due to insufficient cooling, which makes it inconvenient for technicians to demold the casting, resulting in low demolding efficiency and affecting production efficiency.

[0004] Therefore, we propose an air guide cover injection mold. Utility Model Content

[0005] The main purpose of the utility model is to provide an air guide hood injection mold to accelerate the cooling of the mold and prevent adhesion between the mold and the casting, thereby improving production efficiency and effectively solving the problems in the background technology.

When a certain pressure is generated inside the box, the slider moves upward along the slide groove under the influence of the pressure, so that the top plate slowly lifts the molding mold to complete the demoulding, the force is evenly applied, and the demoulding effect is good, thereby improving the product quality of the mold;

[0012] The wind generated by the air supply machine allows the wind to enter the air inlet main pipe, and then the wind in the air inlet main pipe passes through the air supply duct and enters the interior from the bottom of the slider, and supplies air to the bottom of the forming mold through the through hole, so that the air inside the lower mold can circulate, thereby cooling the lower mold, avoiding the situation where the temperature of the lower mold is too high and adhesion occurs during die casting. At the same time, the wind of a part of the air supply duct is supplied to the upper mold through the circulation duct and the connecting duct through the circulation duct and the connecting duct, so that the air inside the upper mold can circulate, thereby cooling the upper mold, avoiding the situation where the temperature of the upper mold is too high and adhesion occurs during the next die casting;

[0013] It should be pointed out that the check valve is one-sidedly ventilated and can only be opened when the circulating duct is supplying air, thereby preventing the mold raw material from entering the circulating duct during die casting; the top plate and the bottom surface of the forming mold are evenly stressed to prevent damage to the workpiece, and the top surface of the top plate is flush with the groove at the bottom of the lower mold. Under the running track of the ejection mold, limit blocks are provided on both sides of the slider, and the slider is slidably connected to the outside of the air supply duct and will not detach from the slide groove, and a sealing rubber ring is provided at the bottom of the top plate to prevent leakage.

[0021] By adopting the above technical solution, the hydraulic telescopic column on the top of the bracket pushes the upper mold to move linearly up and down, so that the upper mold overlaps with the lower mold.

[0022] Furthermore, push rods are provided at the four corners of the top end of the lower mold, and through holes for installing the push rods are provided at the four corners of the bottom end of the upper mold.
