Description
What are Support Pillars?
Support pillars are mold components mounted between the backup plate and the rear clamping plate of a mold. They greatly increase the mold’s capacity to support the projected cavity area and prevent deflection during injection pressure. Typically, support pillars are used when building larger molds.
Support Pillars (Plastic Mold Components) are used in industrial applications. The support pillar assists the support plate when it is undergoing injection pressure, avoiding possible deformations in the plate.
Longer Length Options A Threaded Support Pillar is tapped at both ends to allow a second pillar to be attached for a longer overall length.

DGMF Support Pillar Injection Mold Component’s Drawing
The support pillars are located between the backup plate and the back clamping plate. They are parallel to the spacer blocks reinforcing the core side of the mold structure. The ejector plate has hollow areas to move freely around the support pillars.
The amount of support pillars is estimated on a case-by-case basis. They have the same height as the spacer blocks and usually, they have a cylindrical shape.
The major consideration in establishing the final dimensions of the support pillars is fitting them into the ejector plate area without interfering with the lifters, ejector pins, and/or any other action located on the ejector plate.

Specific functions of mould support pillars
1. Provide structural support
The mould support pillar is an indispensable part of the mould-making process, mainly used to provide structural support.
It can withstand the weight of the mould itself, as well as the various forces and pressures during the mould making process, to ensure the stability and robustness of the mould.
2. Precise positioning
The design and installation of the mould support column can achieve the precise positioning of the mould.
Through the fixed position and size of the support column, it can ensure the accuracy of the matching parts of the mould and improve the quality and precision of the products.
3. Conducting force
In the process of mould making, the mould support column can conduct various forces and pressures.
It transmits the pressure and force from the mould to the supporting platform and machine tool to ensure the stability and accuracy of the mould.
4. Orientation
The mould support pillar is usually designed with adjustable height and direction.
In this way, the height and direction of the support column can be flexibly adjusted according to the needs during the mould-making process, so as to adapt to different mould shapes and process requirements.
5. Prevent deformation
The mould support column can effectively prevent the deformation of the mould in the process of use.
It provides stable support and protection so that the mould can maintain a stable shape and accurate size under high temperature, high pressure, or high-speed operation.
6. Extended service life
The proper design and use of mould support columns can extend the service life of the mould.
It can reduce the wear and tear and damage of the mould, protect the core parts of the mould and improve the economic efficiency of the mould.
7. Convenient for maintenance
The structure of mould support column is simple and easy to maintain.
In the process of mould use, through the cleaning, lubrication, and inspection of the support column, it can ensure its normal working condition and reduce the occurrence of failure and damage.
8. Maintain mould safety
The mould support column can effectively maintain the safety of the mould.
It provides stable support and protection, which reduces the damage of moulds and the occurrence of accidents during the use of moulds.
9. Convenient for mould commissioning
The design and installation of mould support column can facilitate the commissioning of the mould.
During the commissioning process, the height and direction of the support column can be adjusted to make the parts of the mould work more closely together and improve the processing quality of the mould.
Mould support column plays an important role in the process of mould making and using. It provides several functions such as structural support, precise positioning, force conduction, direction adjustment, prevention of deformation, extension of service life, and easy maintenance.
Accurate and reasonable design and use of mould support column can not only improve the quality and precision of the mould, but also prolong the life of the mould and improve the economic benefits of the mould.
