Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pin-inserting moulds, in particular to an injection mould with a detachable pin-inserting function. Background Art
[0002] Injection molds play a key role in the production of plastic products, and their design and performance directly affect the quality and production efficiency of the products. In order to meet the production needs of different products, molds usually need to be frequently replaced and maintained, among which the installation and removal of the pins is an important link. The traditional mold pin replacement process is complicated and time-consuming, which increases production costs and downtime. In order to improve production efficiency and the convenience of mold maintenance, it is particularly important to develop an injection mold with a detachable pin function. This technology can greatly simplify the replacement and maintenance process of the pin, ensure the efficient operation of the mold, improve production efficiency and product quality, and is widely applicable to various injection molding manufacturing industries.
[0003] With the continuous development of mold technology and the continuous improvement of the appearance of injection molded products, injection molds must meet the requirements of high-quality appearance and zero defects, taking into account the service life of the mold, the simplicity and convenience of replacing the pins, and the low maintenance cost. Combined with the injection molds of the water tank frame products that have been designed in the early stage and are already in production, we conducted an analysis. Due to the early mold production and molding, the products have injection nuts and product installation holes, which are all fixed pins on the design core. After the needle breaks, the mold is difficult to repair, and the processing time after welding is long, which delays production. In summary, the water tank frame products that have been produced have installation holes, nuts, etc., and they will continue to break during production, causing maintenance difficulties. Therefore, we provide an injection mold with a detachable pin function. Utility Model Content
