In the mold making and injection molding of plastic molds with Inside unscrewing, choosing the appropriate drive mode and transmission mechanism can achieve efficient and stable mold release and multi-cavity ejection. In practical applications, the appropriate mold design and manufacturing solution can be selected according to specific production requirements and product characteristics.
inside unscrewing injection mould manufacturing:
When manufacturing a injection mould with internal threads, the primary task is to ensure that the mold can meet specific design requirements, including but not limited to the accuracy of the internal thread, the number of die cavities, etc. The manufacturing process of a mold usually includes the following steps:
Design drawing: According to customer needs, carry out detailed mold design, and draw accurate design drawings.
Material selection: Select the appropriate mold material to ensure that the mold has sufficient strength, hardness and wear resistance.
Processing and manufacturing: The use of high-precision machining equipment, according to the design drawings to process the various parts of the mold.
Automatic trip technology
Automatic trip technology can greatly shorten the processing cycle and improve production efficiency. The technology is usually implemented by hydraulic cylinder or motor drive, as follows:
Hydraulic cylinder drive automatic trip
Working principle: Through the hydraulic system to control the expansion of the hydraulic cylinder, so as to drive the release mechanism of the mold to act, to realize the automatic opening and closing of the mold.
Advantages: Hydraulic cylinder drive has the advantages of large power, smooth action, high control accuracy, especially suitable for large or heavy mold trip.
Motor drive automatic trip
Working principle: The movement of the trip mechanism is driven by the motor to realize the automatic opening and closing of the mold. The motor drive can achieve multi-cavity ejection through gear transmission and other mechanisms.
Advantages: The motor drive has the advantages of fast response speed, flexible control, energy saving and environmental protection, especially suitable for the mold that needs to be opened and closed frequently.
Multi-cavity ejection with gear drive
Multi-cavity ejection technology can produce multiple products at the same time in a single injection process, further improving production efficiency. The gear drive is one of the common ways to achieve multi-cavity ejection, and its working principle is as follows:
Working principle: The motor drives the gear to rotate, so as to drive multiple ejector rods to move at the same time to achieve multi-cavity ejector.
Advantages: Gear transmission has the advantages of high transmission efficiency, good stability, easy maintenance, etc., especially suitable for multi-cavity ejection system requiring high precision control.
