How do we choose vertical rubber injection machine?


The following vertical rubber injection machine manufacturers to explain the purchase of vertical rubber injection machine should pay attention to matters.

1. the technical parameters of the machine. When customers buy injection molding machines, they can judge by vertical or horizontal comparison. The so-called "vertical" means that the main technical parameters of the injection molding machine must meet industry standards and be assessed in accordance with industry standards. The so-called "horizontal" is based on the comparison of technical parameters of similar injection molding machines at home and abroad. The parameters of injection molding machines at all levels should be selected according to the material, shape, structure, application field and specific occasions of injection molding products, the structure, quality, precision, cavity quantity, runner type and its structure, shape and size of injection molding products, and the degree of automation of product production capacity.

2. the stability, reliability, safety and service life of vertical rubber injection machine. The stability of the vertical rubber injection machine is mainly manifested in whether the clamping mechanism and the injection molding system run smoothly in each cycle, work silently and without collision, and the noise shall not exceed the industry standard. These conditions are related to the accuracy of mechanical manufacturing and assembly, as well as the reasonable design and structure of the elbow connecting rod. Reliability and service life are mainly reflected in the system stiffness of the clamping mechanism, which is related to the structure, size, material and heat treatment process of the template, tie rod, connecting rod and pin shaft. The plastic warping system of the injection molding machine, such as the structure and manufacturing process of the barrel, screw, screw head, retaining ring and screw drive spindle, is the main force and wear parts of the injection molding machine, which directly affects the service life.

3. integrity. When the mold clamping mechanism is opened and closed, the reliability of the low-voltage protection system involves the safety of man-machine. Injection molding machines need to implement electrical, mechanical, hydraulic joint safety protection system. This protection is mainly reflected in two aspects: one is the full protection of mold, and the other is the full protection of the human body. Before the mold closing, when the safety door is not closed properly, the mold closing should not move; during the mold closing process, if the safety door is not closed to the correct position, the template will stop or automatically open the mold. When the mold is closed, if foreign objects such as inserts fall into the cavity by mistake due to vibration or starting. If the mold is put into the mold by mistake, the mold shall stop closing the mold, or automatically open the mold and give an alarm. Another safety aspect of the injection molding machine is to prevent cold start of the preformed screw. When the material of the screw does not reach the specified temperature and holding time, it is prohibited to start, otherwise it will alarm. The nozzle splash protection device of the vertical rubber injection machine is a necessary device to prevent burns.

The degree of 4. automation should be complete and perfect, and the production efficiency is high. Modern injection molding machines can be operated manually, semi-automatically and fully automatically. As long as the mold design is reasonable, the product can be fully automatic operation from injection filling to ejection and falling, and it can also be equipped with a manipulator to achieve unmanned operation. The core pulling function, hydraulic nozzle control function and fast heating runner probe function can be programmed into the injection molding cycle automatic program for automatic cycle. The high production efficiency is mainly reflected in the short molding cycle of each molded product under normal injection molding process conditions. This reflects the comprehensive performance indicators of the mechanical, electrical and hydraulic systems of an injection molding machine. Therefore, high-quality hydraulic and electronic components and precision manufacturing technology are very necessary to improve the sensitivity and repeatability of the injection molding machine system, and are a reliable guarantee for the efficient operation of the injection molding system.

5. energy saving and environmental protection is an important index to judge the advantages and disadvantages of injection molding machine. Energy saving mainly reflects the water-saving and electricity-saving capabilities of the injection molding machine in terms of heating system (electromagnetic heating) and power drive system (frequency converter, server, etc.) compared with similar machines.) and heat dissipation system to meet normal process conditions. The design of injection molding machine should fully consider the theme of "environmental protection. The injection molding machine should prevent hydraulic oil leakage or excessive noise to create a quiet and noise-free working environment. In addition, the injection molding machine itself should also use more environmentally friendly materials.

6. machine maintenance and overhaul to facilitate. The installation position of various machines such as mechanical, hydraulic, electronic and electrical components should be conducive to the maintenance and overhaul of the machine. At the same time, the generalization and standardization of injection molding machines are also very important to users.

In addition, the production cost, production efficiency, suppliers and operability of the vertical rubber injection machine are all the contents to be considered when purchasing the vertical rubber injection machine.
