Plastic Injection Mould Shorten The Production Cycle, Improve Productivity

The design of the Plastic Injection Mould shall be carried out according to the following steps:

1, to accept the task book

The task book for forming a plastic part is usually made by the part designer, as follows:

1, after the approval of the regular pieces of drawings, and indicate the use of plastic grades, transparency and so on.

2, plastic parts manual or technical requirements.

3, production production.

4, plastic parts samples.

Usually the mold design task book by the plastic parts craftsmen according to the task of forming plastic parts of the task book, mold design staff to shape the plastic parts of the task book, mold design task book based on the design of the mold.

2, to collect, analyze, digest the original data

Collection and finishing of the parts design, molding process, molding equipment, machining and special processing materials to prepare for the use of mold design.

1, digestive plastic parts drawing, to understand the use of parts, analysis of plastic parts of the process, dimensional accuracy and other technical requirements. For example, plastic parts in the appearance of shape, color transparency, the use of performance requirements, plastic parts of the geometric structure, slope, insert and so on is reasonable, welding marks, shrinkage and other molding defects allowed, Equipment, electroplating, bonding, drilling and other post-processing.

Select the plastic parts of the size of the highest dimensional accuracy of the analysis to see if the estimated molding tolerance is lower than the plastic parts of the tolerance, whether to meet the requirements of the plastic parts to meet. In addition, but also to understand the plastic plastic molding process parameters.

2, digestion process information, analysis of the work of the task book proposed by the molding method, equipment model, material specifications, mold structure type and other requirements are appropriate, can be implemented.

Molding materials should meet the strength requirements of plastic parts, with good mobility, uniformity and isotropic, thermal stability. According to the use of plastic parts, molding materials should meet the requirements of dyeing, metallizing conditions, decorative properties, necessary elasticity and plasticity, transparency or opposite reflective properties, adhesiveness or weldability requirements.

3, to determine the molding method

Using direct pressure method, casting method or injection method.

3, plastic parts analysis and injection machine selection

1, clear plastic parts design requirements

Carefully read the plastic parts of the plastic parts, from the plastic products, plastic parts shape, dimensional accuracy, surface roughness and other aspects of the Plastic Injection Moulding process to consider the feasibility and economy, if necessary, with the product designer to explore the plastic parts The type of material and the possibility of structural modification.

2, clear the production of plastic parts

Small batch production, in order to reduce costs, mold as simple as possible; in mass production, should ensure that the quality of plastic parts prerequisite conditions, try to use a multi-cavity or high-speed automated production to shorten the production cycle and improve productivity, Mold the introduction of institutions, plastic parts and flow of the body of the automatic stripping mechanism put forward strict requirements.

3, calculate the volume and quality of plastic parts

Calculate the volume and quality of plastic parts is to use the Plastic Injection Moulding machine, improve equipment utilization, determine the number of mold cavity.

4, Plastic Injection Moulding machine selection

According to the volume or weight of plastic parts to determine the structure of the mold, the initial determination of Plastic Injection Moulding machine model, to understand the use of Plastic Injection Moulding machine and design mold related technical parameters, such as: Plastic Injection Moulding machine positioning circle diameter, nozzle tip diameter and spherical radius, Plastic Injection Moulding machine maximum injection volume, clamping force, injection pressure, fixed template and mobile template area size and installation screw hole position, Plastic Injection Moulding machine rod spacing, closed thickness, open stroke, the trip out of the trip.

4, the mold design of the calculation

1. Concave, punch parts working size calculation;

2. Cavity wall thickness, floor plate thickness determination;

3. Mold heating, cooling system to determine.
