Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold for automobile engine parts. Background Art

[0002] The technical background of injection molds for automobile engine parts involves the injection molding manufacturing technology in the automobile industry, which is to inject molten plastic or metal into the mold, and then form the required parts or products after cooling and solidification. In the automobile industry, injection molding technology is widely used in the production of various engine parts, such as intake pipes, radiator covers, fan blades, etc. With the development of the automobile industry, the requirements for engine parts are also increasing, requiring parts to have lightweight, high strength, high temperature resistance, corrosion resistance and other properties. As an efficient and precise manufacturing method, injection molding technology provides an important solution to meet these requirements. The key to the injection molding technology of automobile engine parts lies in mold design and manufacturing. Mold design needs to consider the structural characteristics, material properties and production process requirements of the parts to ensure that the final parts have the ideal shape and performance. Mold manufacturing requires the use of advanced processing equipment and processes to ensure that the mold has high precision, high durability and stable production capacity. In the injection molding production process, it is also necessary to control the process parameters such as temperature, pressure, injection speed, etc. to ensure that the molten plastic or metal fully fills the mold cavity and avoids defects such as bubbles, short materials or deformation.

The transmission rod 401 is fixedly connected to the rear of the spring telescopic rod 402. The top of the spring telescopic rod 402 is in contact with the end of the tilting rod 404 away from the grabbing head 406. Under the action of the tilting rod 404 and the grabbing head 406, the model is grabbed out of the mold, which reduces the difficulty of operators to remove the model from the mold and improves work efficiency. Models that are difficult to remove may require more complicated operating steps or tools, which increases the difficulty and risk of the operator's work, and may even damage the surface of the model and increase the scrap rate. Example 2

[0022] See also Figure 1-Figure 4 As shown, the unloading mechanism 3 includes a rotating rod 301, a rotating wheel 302, and a friction strip 303. The rotating rod 301 is rotatably connected to the inner wall of the pressurized mold body 1, the rotating wheel 302 is fixedly connected to the surface of the rotating rod 301, and the friction strip 303 is fixedly connected to the surface of the rotating wheel 302. The unloading mechanism 3 also includes: a friction rod 304, an elastic rod 305, and a head 306. The friction rod 304 is slidably connected to the inner wall of the pressurized mold body 1, the elastic rod 305 is slidably connected to the inner wall of the friction rod 304 through a spring, and the head 306 is fixedly connected to the elastic rod 3 05, the surface of the rotating wheel 302 contacts the inner wall of the pressurized mold body 1, the surface of the friction strip 303 contacts the surface of the friction rod 304, and the rear part of the transmission rod 401 is slidably connected to the inner wall of the friction rod 304.

No further manual operation is required, saving labor time.

[0023] When the injection mold of an automobile engine part of the utility model is in use, the operator starts the electric push rod 2, and the electric push rod 2 pushes the pressurizing mold body 1 to perform pressurizing and molding on the U-shaped pressurized mold. During the movement of the mold body 1, the rotating wheel 302 rotates through friction with the inner wall of the U-shaped pressurized mold through the friction strip 303, and contacts with the friction rod 304, so that the friction rod 304 moves downward along the inner wall of the pressurizing mold body 1. The friction rod 304 moves downward to drive the elastic rod 305 and the top head 306 to move downward at the same time. At the same time, the friction rod 304 drives the transmission rod 401 to move downward, and the transmission rod 401 drives the spring telescopic rod 402 to retract into the interior of the limit frame 403 through the spring. At this time, the tilting rod 404 loses the pressure applied by the spring telescopic rod 402 and tilts along the fixed block 405 through the torsion spring, so that the tilting rod 404 drives the grabbing head 406 The tilting is used to prepare for grabbing the mold that is about to be formed. When the raised modeling part of the pressure mold 1 contacts the plastic material in the pressure mold and the molding is completed, the operator controls the electric push rod 2 to move in the opposite direction. At this time, the rotating wheel 302 rotates in the opposite direction through the friction force of the friction strip 303, so that the friction rod 304 drives the spring telescopic rod 402 to move up through the transmission rod 401, and lifts the bottom of the tilting rod 404, so that the grabbing head 406 tilts in the opposite direction to grab the edge of the molded model, reducing the difficulty of the operator to remove the model from the mold and improving work efficiency. At the same time, the friction rod 304 drives the elastic rod 305 and the top head 306 to move in the opposite direction to grab the model for unloading, thereby improving the continuity of the device operation, and the model is flexibly unloaded under the action of the elastic rod to prevent the newly formed model from deforming during the unloading process.
