Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a mold blank flipping structure. Background Technology

[0002] A mold is a set of molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the object's shape by changing the physical state of the material being molded. Often called the "mother of industry," it is a tool that, under the action of external force, transforms a blank into a part with a specific shape and size. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of engineering plastics, rubber, ceramics, and other products. A mold has a specific contour or internal cavity shape. Using a contour shape with cutting edges allows the blank to be separated according to the contour line shape (blanking). Using an internal cavity shape allows the blank to obtain a corresponding three-dimensional shape. A mold generally consists of two parts: a moving mold and a fixed mold (or a punch and a die), which can be separated and joined. When separated, the part is removed; when joined, the blank is injected into the mold cavity to form the shape. Hardware molds are divided into: stamping molds (such as blanking molds, bending molds, deep drawing molds, piercing molds, shrinking molds, embossing molds, bulging molds, forming molds, etc.), forging molds (such as die forging molds, upsetting molds, etc.), extrusion molds, die casting molds, forging molds, etc. Molds are precision tools with complex shapes. They bear the expansion force of blanks and have high requirements for structural strength, rigidity, surface hardness, surface roughness and processing accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.

[0003] The mold blank is the skeleton and foundation of a mold, providing a basis for the installation and positioning of other mold components. Whether in injection molds, die-casting molds, or stamping dies, the mold blank is an indispensable component. It typically consists of several steel plates or castings that are precisely machined and assembled to form a framework capable of housing other mold components.

[0004] The mold base serves several key functions. First, it provides a robust structure to ensure the precision and long-term stability of the mold. Second, it provides precise positioning and guidance for the various components of the mold, ensuring consistency and accuracy of the finished product. Furthermore, the mold base also houses the mold's cooling and heating systems, which are crucial for guaranteeing the quality of the injection molded parts and controlling the molding process.

[0005] The composition of a mold blank varies depending on the type of mold and specific requirements, but it typically includes a base plate, fixed mold plate, moving mold plate, guide pillars, and guide sleeves. These parts are precision-machined and assembled to form a robust and precise whole. The mold blank manufacturing process requires advanced machining techniques and rigorous quality management to ensure it meets high standards for mold manufacturing. Currently, products are not easily detached from the surface of the mold blank, thus affecting production efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a mold base flipping structure that solves the problem that products are not easy to fall off the surface of the current mold base, thus affecting production efficiency.

The sheet metal is placed on the surface of the mold blank, and the upper stamping die is activated to stamp the sheet metal. After the stamping die is reset, the spring force will push the mold blank lifting and stabilizing rod to move upward.

Then, the insert rod is pulled out from the inside of the first slot, the mold blank is turned 180 degrees around, and the insert rod is pushed downward to insert into the inside of the second slot to position the mold blank. The back of the mold blank is tapped with a tool to make the product fall off.

[0009] Furthermore, the surface of the mold base lifting and stabilizing rod is movably connected to the interior of the auxiliary lifting sliding through hole.

[0010] Furthermore, the top of the lifting ring is provided with an insertion hole that communicates with the inside of the rotating groove, and a rod is inserted into the insertion hole.

[0011] Furthermore, a first slot is provided on the upper surface of the mold base support rotating rod, and the bottom end of the insert rod is inserted into the interior of the first slot.

[0012] Furthermore, a second slot is provided on the lower surface of the mold base support rotating rod.
