Analysis of Automobile Injection Moulds

We all know that automobiles are very dependent on the application of plastic parts.At the same time,automobile products are constantly updated.Only by mastering the key and difficult points of mold production of plastic parts can mold production meet the development needs of the automotive industry.

The Basics of Injection Mold Design

1. 1) Plastic product design is the focus

  Plastic products are definitely a key link in the design of injection molds.The design of plastic products requires nothing more than to simplify the model of plastic products as much as possible,especially the design of sags and unkulations.It is best not to appear in the design of plastic products.The requirement of simplicity in the design of plastic products is a general direction,because there are many small links in the design of plastic products.Simplified design is a requirement for each refinement link of plastic products.The basic requirements of the link,such as the design of the thickness of the injection mold,should make the wall thickness of the mold as uniform as possible while evolving,and avoid inappropriate glue positions with uneven thickness.The stiffness and hardness also need to meet the standards,which is a key link to ensure the quality of plastic parts.

1. 2) Classification of Plastic products in structural design

  The inner and outer sides of the plastic product must have a demoulding slope that meets the demoulding standard,which is more conducive to demoulding.In order to make the appearance smooth and the demoulding is not hindered by friction,the plastic products should be as streamlined and smooth as possible in terms of radian and texture.Plastic products have sharp corners,and these corners are rounded.For the radian problem,in the peripheral corners of the inner and outer sides of the plastic product,the radian tension should be larger,which is very necessary.

The Basis Requirements of a Forming Mold For Parts
The strength and hardness must meet a certain standard,otherwise it will not be able to withstand friction,which will affect the construction quality.The minimum hardness requirement should not be lower than HRC35,and the hardness of very few special requirements should be above 50~52HRC.The surface is shiny and can be achieved by polishing.In addition,the cavity parts needs to be polished.The sample of the product cannot deviate from the product requirements,and then the management and construction technology are used to improve production efficiency and save costs.

Number of Clear Cavities
  The method of determining the number of cavities can use all the injection machines,and then confirm the number of them by the amount of injection and the rated clamping force of the injection machine.Other factors need to be combined in the process of the number of model cavities,such as: molding process,precision and maintenance,and economy.

Indentify the Fractal Line and the mold Parting Surface
The determination method of the fractal line can be determined according to the shape of the part.The function of the fractal line is to divide the product into two parts,and the dividing line exists the same.The two parts that are divided into one part are formed by the fixed mold,and the other part is formed by the movable mold.To obtain the parting surface of the mold,the fractal line can be used,and the parting surface of the mold can be determined by scanning the fractal line around the two molds.

4.1 Parting Surface Design Considerations
The step parting surface generally needs to have an insertion inclination angle of 3 to 5 degrees when facing the step parting surface,and the angle cannot be lower than 1.5 degrees.Sometimes multiple step surfaces appear in a parting surface at the same time.
In this case,the same angle is used to act on the angle A,which makes the processing easier and more convenient.
There is one part of the parting surface of the mold that needs special attention,that is,to ensure that each same surface has a sealing distance,and at the same time,it is necessary to ensure the effectiveness of this distance,so that the plastic melt can not easily flow out during the injection process,and the distance between the sealing materials. This name corrsponds to this effect,which can block the material.In the process of creating the parting surface,if there is a parting surface with a large difference in height such as a curved surface,an inclined surface,and a step,whether it is one or more,a reference plane must be set for it,which can facilitate processing and measurement.
4.2 Basic Principles of Parting Surface Design
The molding plastic needs to be retained on the half mold after the mold is opened.Of course,this is under the premise of the ejection mechanism.Generally,the ejection mechanism half mold is a moving mold,and only the ejection mechanism half mold that appears in a  few special cases is on the die.
Some plastic products will come with metal inserts.Since the inserts do not have the function of shrink wrapping the punch,the shape cavity is usually designed on the side of the movable mold.Once this happens,demolding becomes very difficult.If the coaxiality structure is inside the movable mold or the fixed mold,if it is formed on both sides of the two molds,it is difficult to ensure the accuracy of the coaxiality.This situation is mostly due to manufacturing errors and assembly errors caused.

  There are certain requirements for the locking of the mold,and this requirement must be satisfied.In order to meet this requirement,plastic products are generally placed at the clamping place of the ground motion quantitative mold.For lateral fractal surface.This can greatly reduce the locking force.In addition,the parting surface sometimes has a cruved surface.When this phenomenon occurs,a positioning mechanism must be added,and the selection of the parting surface should not affect the shape of the plastic product as much as possible.If the plastic product has diamond lines and tangent lines in its shape,it is not suitable for the selection of parting surfaces.

The parting surface must be selected to be realtively smooth and without obvious sharp corners,so that the segmentation will not affect the quality and shape.Although it it not absolute,the probability of occurrence is still high.Be sure to arrange the size and quantity of the inner mold inserts reasonably.
