When a product is born, mold opening is essential, and when we need to find a mold opening factory, we often think that injection molds and plastic molds are a meaning, then understand the difference between plastic molds and injection molds, please read this article Will take you to understand the difference!
Plastic mold, a combined plastic mold for compression molding, extrusion molding, injection molding, blow molding and low foam molding, mainly comprising a combination of a die assembly substrate, a die assembly and a die combination card A concave mold of a deformable cavity, a punch having a variable core composed of a punch combination substrate, a punch assembly, a punch combination card, a cavity cutting assembly, and a side cut composite plate. Coordinated changes in the die, die and auxiliary forming systems. It can process series of plastic parts of different shapes and sizes.
Injection molds are a tool for producing plastic products; they are also tools that give plastic products complete structure and precise dimensions. Injection molding is a processing method used in mass production of complex parts of certain shapes. Specifically, the plastic melted by the heat is injected into the cavity by the high pressure of the injection molding machine, and after cooling and solidifying, the molded article is obtained. The injection mold consists of two parts: a movable mold and a fixed mold. The movable mold is mounted on the moving template of the injection molding machine, and the fixed mold is mounted on the fixed template of the injection molding machine. In the injection molding, the movable mold and the fixed mold close constitute a casting system and a cavity, and when the mold is opened, the movable mold and the fixed mold are separated to take out the plastic product. In order to reduce the heavy mold design and manufacturing workload, most of the injection molds use standard mold bases.
It can be seen from the above that there is still a certain difference between the plastic mold and the injection mold, which also facilitates communication between us and the plastic mold manufacturer to avoid making mistakes.
In fact, many of the construction techniques used in car lights are emerging two-color injection molding in recent years. In fact, the embodiment of this process is to have two different colors when the product is processed. When the product is processed, the procedures involved are still complicated. For many people, this two-color injection molding process is very versatile, and general electronic products are the most commonly used.
Two-color injection molding in mobile phone battery applications
The mobile phone that everyone usually uses, after removing the battery, the exposed plastics are generally of different colors. When processing this product, it is necessary to use special two-color injection molding. Generally, when using this two-color injection molding process, the best finished product may be a color, but if you want to be your favorite color, sometimes there is no way to do a color.
Two-color injection molding has broad prospects
For many people, two-color injection molding has helped him a lot, and it is also a major breakthrough in related industries. I hope that everyone can pay more attention to this process, and in the near future, it will definitely give you even more surprises. In fact, when processing plastic products, the accuracy of the mold is very high. When you use the new two-color injection molding process, you must first perform the first shot, then rotate the mold one hundred and eighty degrees before the second shot.
The new mobile phone uses a two-color injection molding process that is unobtrusive and feels good.
Many of the latest mobile phones that are put on the market basically use this two-color injection molding process. In fact, the first button mobile phone is the most extreme embodiment of this technology. The product produced by this two-color injection molding process can not only achieve the beautiful effect, but also feel better when touched. You must also have a deep understanding. The cost performance of related products is also very high.
Usually, the mold has two parts, an upper mold and a lower mold. The steel plate is placed between the upper and lower molds, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the mold is obtained or the corresponding waste is removed.
Specific plastic mold processing process:
1. The bottom surface is processed and the processing volume is guaranteed;
2. The benchmark of the casting blank is corrected, and the 2D and 3D surface balance inspection;
4. Before semi-finishing, the alignment of the side datum ensures accuracy;
5, semi-finished 2D, 3D profile, finishing all types of installation work surface (including the limit block mounting surface and contact surface, insert mounting surface and back surface, punch mounting surface, scrap cutter mounting surface and back surface) , spring mounting surface and contact surface, various stroke limit working surface, wedge mounting surface and backrest surface), semi-finishing all kinds of guiding surfaces, guiding holes, leaving the finishing process reference hole and height reference surface, and recording data;
6, inspection and review processing accuracy;
7. The setting operation of the fitter;
8. Before the finishing, the reference hole of the process reference hole is corrected, and the remaining amount of the insert is checked;
9, finishing surface 2D, 3D, side punching surface and hole position, finishing process reference hole and height reference, finishing guide surface and guide hole;
10. Inspection and inspection processing accuracy.
