Advantages of CNC Machining Plastic Bottle Cap Molds

Plastic bottle cap molds are mainly used to manufacture plastic bottle cap products. What is the numerical control of plastic bottle cap molds? Numerical control is the abbreviation of digital control. That is, the digital information is used to represent the motion parameters of the machine tool or the tool, and the digital information is sent to the computer, and the plastic bottle cap mold is controlled by the computer, so that the required relative movement between the processed part and the tool is produced, so as to realize the processing of the parts. It is a high-efficiency automatic machine tool controlled by computer. It comprehensively applies the new achievements in automatic control, computer technology, precision measurement and machine tool structure. CNC machine tools are generally composed of CNC system (computer and interface circuit), driving device (servo circuit and servo motor), host (bed, column, spindle, feeding mechanism, etc.) and auxiliary devices (hydraulic device, pneumatic device, exchange work It is composed of several parts.

(1) High degree of automation

When machining parts on the mold, the entire machining process is automatically completed by the CNC system to control the moving parts of the mold according to the machining program. The operator only needs to press the operation button and observe whether the machining process is normal.

(2) Strong adaptability

The process of realizing the processing of the plastic bottle cap mold is controlled by the program. When a part is to be processed, the processing program must be written according to the size, shape and technical requirements on the part drawing, and then sent to the computer of the numerical control system. When the object to be processed changes, in addition to changing the tool and fixture, it is only necessary to write a new processing program according to the processing requirements of the new object to achieve processing. Therefore, the processing range of the mold is very wide, which can save a lot of special fixtures, especially suitable for single-piece small batch processing.

(3) Good processing quality and high precision

Most of them use high-performance spindle, servo drive system, high-efficiency and high-precision transmission components (such as ball screw pair, linear rolling guide, etc.) and mold structure with high dynamic rigidity. Thermal deformation measures can maintain high geometric accuracy and positioning accuracy. And because the mold is automatically processed, the human operation error is reduced, so it has high processing accuracy and dimensional consistency.

(4) High production efficiency

Due to the high degree of automation of CNC, the work of line drawing, fixture design and manufacture, multiple clamping positioning and detection is omitted in the processing process, so the production efficiency of CNC machining is high.

(5) Easy to form network control

A host computer can be used to control multiple molds through the network, and a communication network can also be established between multiple molds, which is conducive to the formation of an integrated manufacturing system integrating computer-aided design, production management and manufacturing. Of course, the application of CNC machining method also has the disadvantages of high mold price, complex technology, and high requirements for mold maintenance and programming technology. In order to make full use of the high performance of the mold and give full play to its advantages of high efficiency, it is necessary to effectively solve a series of problems such as the preparation of parts processing programs, the supply and adjustment of tools, and the training of maintenance personnel. In addition, the mold is not suitable for processing parts with simple shape, low technical requirements, excessive blank allowance and uneven allowance.
