Description

Technical Field

[0001] The utility model relates to the technical field of hemp fiber seat backboard production, in particular to an injection mold for a hemp fiber seat backboard. Background Art

[0002] Hemp fiber seat back is a seat back material, usually made of a mixture of hemp fiber and synthetic resin (such as plastic). Hemp fiber seat back has the characteristics of light weight, environmental protection, wear resistance, breathability, etc., and is suitable for the production and manufacturing of car seats, furniture seats and other fields. Hemp fiber, as a natural fiber, has good tensile strength and wear resistance, and is also environmentally friendly and degradable. It is widely used in seat back materials. Through injection molding technology, hemp fiber can be mixed with plastic and injected into the mold for molding to produce a sturdy and durable seat back product. Injection molds are required during injection molding, but most of the hemp fiber seat back injection molds in the existing technology still have problems that need to be solved during use.

[0003] In the existing technology, most of the hemp fiber seat back injection molds are fixed to the output shaft of the injection molding machine or the hydraulic push rod by bolts or welding. The bolt fixing and welding fixing operations are relatively complicated and time-consuming, making maintenance work difficult, increasing the workload of the staff, and also affecting the progress of production work. Therefore, it is necessary to design a hemp fiber seat back injection mold to solve the above problems. Utility Model Content

By setting an insert plate and a limit groove, when installing the mold, the insert plate is inserted into the limit groove to limit the position of the fixed shaft, so that the mold can be installed and the stability of the mold during use can be ensured. When disassembling the mold, the insert plate is moved out of the limit groove, the fixed seat can be removed, and the mold can be removed, so that the mold can be replaced or maintained. This effectively solves the problem that the fixing method of most of the hemp fiber seat back injection molds in the existing technology proposed in the background technology is relatively complicated and time-consuming during installation and disassembly, making maintenance work difficult, increasing the workload of the staff, and affecting the progress of production work. Therefore, it is easy to install and disassemble the mold, simple to operate, and convenient for maintenance work, which can reduce the workload of the staff and improve work efficiency.
