What are the injection mold opening steps?

The opening of injection mold is an important link in the production process of plastic products, which involves several steps from design to manufacturing. The following will introduce the injection mold opening step process in detail.

1. Design phase

(1) Product analysis: First of all, it is necessary to conduct a detailed analysis of the product to be injected, including the size, shape, material, wall thickness, etc., to ensure the rationality and feasibility of the mold design.
(2) Mold structure design: According to product characteristics, design a reasonable mold structure, including parting surface, gate location, cooling system, etc.
(3) Drawing mold drawings: Use CAD and other drawing software to draw detailed mold drawings, including three-dimensional models and two-dimensional drawings, for subsequent processing and manufacturing.

2. Manufacturing stage

(1) Material preparation: According to the design drawings, prepare the required mold materials, such as die steel, guide post, guide sleeve, etc.
(2) Roughing: rough machining of mold materials, including milling, drilling, etc., to form the basic mold shape.
(3) Finishing: on the basis of rough machining, finishing, including polishing, grinding, etc., to ensure the accuracy and surface quality of the mold.
(1) Assembly and debugging: Assemble the machined mold parts, check the cooperation of each part, and debug to ensure the normal operation of the mold.

3. Trial stage

(1) Mold installation: the assembled mold is installed on the injection molding machine, fixed and adjusted.
(2) trial mold production: use plastic raw materials for trial mold production, observe the molding situation of the product, and check whether there are defects or undesirable phenomena.
(3) Adjustment and optimization: According to the test results, the necessary adjustment and optimization of the mold to improve product quality and production efficiency.

4. Acceptance stage

(1) Quality inspection: a comprehensive quality inspection of the mold, including dimensional accuracy, surface quality, coordination, etc.
(2) Delivery: After acceptance, the mold is delivered to the user for formal production.

Through the above steps, the whole process of injection mold opening can be completed. In the entire process, it is necessary to strictly follow the design specifications and manufacturing standards to ensure the quality and performance of the mold. At the same time, it is also necessary to pay attention to safe production and environmental protection to ensure a clean and safe working environment.
