Description

Technical Field

[0001] This utility model relates to the field of cutting edge assembly technology, and in particular to a wear-resistant cutting edge assembly for molds. Background Technology

[0002] In modern manufacturing, molds are key tools for producing various precision parts. Their manufacturing precision and quality directly determine the performance and quality of downstream products. The production and processing of molds often involves complex shape cutting, high-precision dimensional control, and cutting of various mold materials. From the processing of large injection molds in automotive parts manufacturing to the manufacturing of small stamping dies required for the production of precision electronic components, the application fields of molds are extremely wide. Different fields have different requirements for the performance of molds, but they all impose stringent standards on the processing precision and surface quality of molds. At the same time, the mold manufacturing process can be described as a complex system engineering project, involving a variety of advanced manufacturing technologies and processes. In the cutting and processing stage, various mold materials need to be precisely cut and sized. There are many types of mold materials, including common alloy mold steel, high-strength cemented carbide, high-temperature resistant ceramic materials, and emerging metal matrix composite materials. While these materials have excellent properties, they also bring great difficulties to the cutting and processing.

[0003] Currently, cutting edge assemblies on the market mainly consist of a cutting edge body and a tool body. Traditional wear-resistant cutting edges for molds have significant drawbacks in the tool replacement process, making rapid replacement difficult. In early mold processing, the cutting edge and tool body were often connected by welding or riveting, which, under the technological conditions at the time, ensured a certain degree of stability for the cutting edge during operation. However, this caused great trouble when the cutting edge wore out and needed replacement. Taking welding connections as an example, when the cutting edge wore out, specialized equipment was needed to heat and disassemble the weld. This process was not only complex but also required extremely high precision equipment. Slight carelessness could damage the tool body, affecting its weight. Reusability and riveting also present problems. Removing rivets can easily cause local deformation of the tool body, and cleaning the riveted area is tedious, consuming a lot of time and labor costs. At the same time, from the perspective of production efficiency, the inconvenience of quickly replacing the cutting edge seriously restricts the overall efficiency of mold manufacturing. During mold processing, cutting edge wear is an unavoidable phenomenon, especially when processing high-strength and high-hardness mold materials, such as new alloy mold steel and cemented carbide, the cutting edge wears faster. Once the cutting edge wears to the point that it can no longer meet the processing accuracy requirements, but cannot be replaced in time, the entire mold production process must be interrupted. This not only wastes production time, but also significantly increases the downtime of the production line. Utility Model Content

A threaded sleeve 207 is fixed on the inner wall of the gear plate 206. By sliding the sliding plates 203, the threaded shaft 205, which is slidably connected to the inner wall of the gear plate 204, is rotated, causing the threaded shaft 205 to rotate on the inner wall of the gear plate 206. This allows the gear plate 204 fixed on the rear side of the outer wall of the sliding plate 203 to mesh with the gear plate 206, thereby fixing and disassembling the protective shell 202 that slides on the outer wall of the engaging shaft 7, thus meeting the usage requirements.
