Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a rapid prototyping automatic mold opening mold. Background Art

[0002] Molds are important tools used to shape objects in industrial production. They are designed into specific shapes and structures according to different product requirements. Molds can process raw materials into finished or semi-finished products with precise sizes and shapes through various processes such as injection molding, die-casting, and stamping. Their quality directly affects the precision, appearance, and production efficiency of the product. In the manufacturing industry, molds cover many fields from automobiles and electronic products to daily necessities, providing reliable guarantees for large-scale, high-efficiency, and high-quality production.

[0003] Existing technologies include a utility model with publication number CN210996082U, which discloses a die die for rapid prototyping of automobile parts.

The punch pressing platform and the forming part punch prevent the failure of the die pressing caused by the mold being too large, ensuring that the forming part punch can be completely pressed and formed. The die groove and the gravity hydraulic block improve the working efficiency of the die pressing mold for the rapid prototyping parts of the automobile, so that it can press different types of molds at the same time and ensure the quality of the molded parts. The push block improves the automation process of the die pressing mold for the rapid prototyping parts of the automobile, facilitates the feeding and discharging of molded parts, and solves the problem that the existing die pressing mold can only make one type of mold when pressing the mold, which is inefficient.

[0004] In the process of machining workpieces with the help of molds, some existing molds on the market need to use multiple cylinders to eject the processed workpieces after machining is completed. During the operation of the cylinders, multiple cylinders rely on the control of control equipment to ensure synchronization with each other. Since the cylinders will wear and tear during use, when the cylinders wear and tear occur, the synchronization between the cylinders will change, which will lead to inconsistent speeds of the cylinders lifting the workpiece, causing damage to the workpiece.

By setting up auxiliary components, the mold can be ejected during the expansion process, thereby reducing the problem that the synchronization of the cylinders is prone to decline during use when the mold is ejected with the help of multiple cylinders, resulting in uneven force on the workpiece and damage, and further improving the processing quality of the mold.
