Factors Affecting Plastic Mold Making Structure and Single Mold System in Suzhou
1. Cavity layout. Suzhou plastic mold making determines the number and arrangement of cavities according to the geometric structure characteristics, dimensional accuracy requirements, batch size, mold manufacturing difficulty and mold cost of plastic parts.
1. Cavity layout. Suzhou plastic mold making determines the number and arrangement of cavities according to the geometric structure characteristics, dimensional accuracy requirements, batch size, mold manufacturing difficulty and mold cost of plastic parts.
2. Determine the parting surface. The position of the parting surface should be convenient for mold processing, exhaust, demolding and forming operations, and is conducive to the surface quality of plastic parts.
3. Determine the gating system and exhaust system (exhaust method, exhaust slot position and size).
4. Select the ejection method (ejector rod, jacking tube, push plate, combined ejection), and determine the side concave treatment method and core pulling method.
5. Determine the cooling and heating method, the shape and position of the heating and cooling tank, and the installation position of the heating element.
6. According to the material, strength calculation or experience data of Suzhou plastic mold production, determine the thickness, overall size, overall structure and position of all connection, positioning and guiding parts of the mold parts.
7. Determine the structural form of the main forming parts and structural parts.
8. Consider the strength of each part of Suzhou plastic mold production, and calculate the working size of the molded parts.
If these problems are solved, the structural form of the mold will be solved naturally. At this point, we should manually draw the mold structure sketch, ready for the formal drawing.
suzhou plastic mold making drawing:
It is required to be drawn in accordance with the national drawing standards, but it is also required to combine the factory standards and the customary drawing methods of the factory not specified by the state.
Before drawing the general assembly drawing of Suzhou plastic mold, the process drawing should be drawn, and the requirements of part drawing and process data should be met. For the size guaranteed by the next process, the words "process size" shall be marked on the drawing. If no processing is performed after molding except for repairing burrs, the process drawing is exactly the same as the part drawing.
Mark the part number, name, material, material shrinkage rate, drawing scale, etc. under the process drawing. The process drawing is usually on the mold assembly drawing.
As far as possible, the final assembly drawing should be drawn on a scale of 1:1, starting from the cavity, and drawing the main view and other views at the same time.
Suzhou plastic mold production assembly drawing should include the following:
1. Structure of mold forming parts
2. The structure of the gating system and the exhaust system.
3. Parting surface and parting parts are taken.
4. Profile structure, location and position of all connectors and guides.
5. Mark the height dimension of the cavity (not mandatory, as required) and the external dimension of the mold.
6. Auxiliary tools (die taking tools, die removal tools, calibration tools, etc.).
7. Prepare the serial number of all parts in order and fill in the list.
8. Marking technical requirements and instructions.
Technical Requirements and Contents of Suzhou Plastic Mold Manufacturing Assembly Drawing
1. Performance requirements for certain systems of molds. For example, the assembly requirements of the ejection system and the slider core pulling structure.
2. Mold assembly process requirements. For example, after the mold is assembled, the fit clearance between the parting surface and the mating surface must not be greater than 0.05mm. The parallelism of the upper and lower parts of the mold should meet the requirements, and indicate the size of the component and the requirements of the size.
3. Mold use, assembly and disassembly methods.
4. Anti-oxidation treatment, mold number, lettering, marking, oil seal, storage and other requirements.
5. Mold test and inspection requirements.

On May 20, 2023, Xinyu launched an outdoor expansion activity with the theme of "Cohesion to Win the Future" in Anji Zhuhai. Through the development of the activity, the cohesion and overall centripetal force of the employee group were enhanced, and the positive communication between employees was established., Mutual trust, unity and cooperation, cultivate team awareness, and increase the sense of responsibility of employees. One by one well-designed team building games aroused everyone's strong interest and enthusiasm. In the process of cross-game experience, the team members won one by one with the cooperation. This activity not only enhanced the cohesion between Xinyu employees, but also cultivated a tacit understanding between each other.
2023/9/21, the launching ceremony of the digital supply chain platform of Wujiang Xinyu Precision Mould Co., Ltd. was solemnly held in Suzhou Taihu International Conference Center. Gan Xiangquan, general manager of the company, spoke on behalf of Xinyu Company. Since then, the company has officially taken a big step towards a new model, a new journey and a new future!
Plastic mold design and manufacturing personnel must carefully carry out mold design according to the above basis and requirements provided by customers. When designing molds, the above contents should be specified one by one and expressed in the form of drawings and technical documents. Then let's learn about the detailed operation of the general procedures for plastic mold design and manufacturing!
Any product has its own quality, so does a set of plastic mold design and manufacturing. Some factories can only produce low-quality molds, while others can produce high-quality plastic molds. Then, let's learn about the design and manufacturing process and technological process of plastic molds!
