Design and optimization of injection mold for flashlight hijab

Plastic molded products are widely used in modern industry. Among them, flashlight hijabs are a common plastic product in daily life. The optimization of injection mold design is of great significance for improving production efficiency, reducing costs, and ensuring product quality. This article will discuss in detail the functional requirements, material selection, mold design, etc. of the flashlight hijab.

一. Functional design:

As a plastic product, the flashlight cover must meet its purpose in terms of unctional design, that is, as the covering part of the flashlight, protecting the battery and circuit board. Since it does not bear large external forces, it does not have high requirements for impact, vibration, etc. In addition, considering that its working environment is room temperature, the thermal performance requirements for the material are relatively low.

二. Material：

selection: According to the functional requirements and production batch of the flashlight cover, PC (polycarbonate) can be selected as the main material. PC has good mechanical properties and heat resistance, is suitable for injection molding, and has relatively low cost, suitable for medium or large batch production.

三. Mould design:

1. Intelligent mold parting: Use CAD software for intelligent mold parting. According to the structural characteristics of the flashlight cover, determine the overall layout of the cavity, select the appropriate parting surface, simplify the moldparting process, and improve design efficiency.

2. CAE simulation analysis: Carry out simulation analysis of the injection molding process through CAE software, including analysis of mold filling flow, pressure holding process, cooling process and warpage. Through simulation, the filling condition of the product, the location of defects, and the optimal location and number of gates can be predicted to optimize the injection molding process parameters.

3. Expert mold base

system: select the appropriate standard mold base according to the design parameters, construct the three-dimensional entity of the mold, and ensure the quality and accuracy of the mold.
