Analyzing the causes of errors and summarizing lessons learned during work is an important way to improve work efficiency.
Fault case: The tie bar of a Haitian injection molding machine broke. The tie bar was replaced and the balance was adjusted without the need for special tools.
Clamping force generation: The four tie bars of the injection molding machine's inner columns pass through the crank base and fixed template, positioning the movement direction of the base and template. The parallelism between the base and the fixed template is determined by the position of the nuts at both ends of the tie bars. In the process of the driven template contacting the mold to the extension of the crank arm, due to the obstruction of the mold, the moving template can no longer move forward, and the base tends to move backward, putting the tie bar in a tensioned state. The clamping force is equal to the tensile force *4 corresponding to the variable of a single tie bar. It is equal to the pressure of the moving template on the mold and the pressure between the moving mold and the fixed mold.
Tie barThe stress balance is that when the mold is closed, the four tie bars have the same tensile force, or the deformation of the tie bars is equal. It is impossible to accurately install without specialized tools.
Author's pre-action thoughts: The front fixed plate and fixed nut of the tie bar are not installed, and the closing of the mold causes the base to moveTie barback, causing a force balance on the base; the front fixed nut is tightened through mold adjustment to complete the balanced installation.
Scenario:
1. Remove the tie bar and tighten the rear mold adjusting nuts to the same position.
2. Return the tie bar insert to the same distance (measure the distance between the mold adjusting nut and the base or flow path).
3. Install the front and rear nuts and front and rear fixed plates of the tie bar, so that the distance between the four corners of the base and the fixed template is approximately equal.
4. Install the mold and adjust it normally. The mold is closed and is in a non-high-pressure state. Remove the front fixed nut and front fixed plate of the tie bar, and only remove the rear fixed plate.
5. Give fourTie barthe same forward distance, raise the high pressure, that is to say, the tie bar will retreat, so the force is repeatedly uniform.
6. Install the front fixed nut and front fixed plate. This step is very important. The nut cannot be tightened. Tighten the fixed nut by adjusting the mold.

Injection Molding Machine Accessories: Detailed Analysis of Common Temperature Problems!
Injection molding machine accessories. In co-ordinated control, the direction of the temperature sensor in the mold is critical. When placing the temperature sensor, the user must consider its shape, structure, and the direction of the cooling channels. In addition, the temperature sensor cannot be placed arbitrarily; it should be placed in an area that has a critical effect on the quality of the injection molded product. There are many ways to connect one or more high-temperature mold temperature controllers to the controller.
Injection Molding Machine Accessories: Standard Maintenance for Injection Molding Machines
Injection molding machine accessories. Everyone should formulate appropriate daily, monthly, and annual maintenance plans based on the condition of the equipment itself, and carefully implement them for each machine according to the plan. Before using the equipment every day, we should check whether each part of the equipment is normal, such as whether the machinery is working normally, whether the heating conditions of each part are normal, whether the circulating water pipes are leaking, whether the emergency stop button can cut off the motor power supply, etc.
What should be noted when repairing a faulty piston rod?
Piston rod failure is normal. The key is to pay attention to the precautions during specific maintenance. If non-professionals perform maintenance, many problems may arise. If possible, choose professional personnel. Maintenance efficiency and its own use value will be higher. We recommend that everyone should understand the following precautions when understanding piston rod maintenance.
What are some applications of piston rods?
In fact, even if we don't mention it, everyone should know quite a bit about piston rods. Of course, to ensure the efficiency of the piston rod, we must guarantee its performance and quality. If more friends are interested in this field, you can also Tel us to discuss your views, I believe this will be helpful to our work.
Connecting structure of piston rod and piston and how to choose piston rod
Piston rods offer significant advantages in practical applications, and the connecting rod structure of the piston is also unique. When used in combination, it is essential to carefully select hydraulic cylinders that demonstrate good operating and production performance. Such products will be highly reliable. The connection structure between the piston rod and piston, and the manufacturing method of the hydraulic cylinder with this piston rod, are essentially the same.
What does the mold pull rod spacing mean in the injection molding machine parameters?
The actual usable area of the template: the greater the distance between the ejector rods, the greater the actual width and height of the grinding tools that can be accommodated. Because injection molding machines need to install plastic injection molds between the moving template and the fixed template, plastic products can be processed. If the mold is to be installed between the two templates, it must pass through two adjacent ejector rods, so the shape of the mold must be smaller than the spacing between the ejector rods.
