What Is Injection Mold Side Action?
Side actions in injection mold represent a specialized mechanical element within mold design. Here are the critical aspects:
- The movable side action operates through slides and cores as its movement elements.
- Molded parts activate these slides through mechanical, hydraulic, and pneumatic processes during the production cycle.
- The mold features move across directions perpendicular to the mold’s opening and closing movements to create intricate features.
- The mold opens after the part solidifies when the side actions return to their original position. The method ensures an easier release of molded parts after processing.
Nowadays advanced injection molding designs require side actions to achieve precision and develop highly detailed features in parts.

How does Injection Mold Side Action Work?
The operation of side action follows a systematic process. The process goes like this:
Side Action Deployment
Side action molding setups help create features such as threads, and deep undercuts. In fact, a standard mold up and down motion cannot create these features. As dictated, side actions are introduced in the mold from its sides to generate complicated designs.
Side Core Activation and Mold Closure
Here, side actions cam operate together with hydraulic cylinders and pneumatic systems. The mold closure activates the cam which drives the side core into its designated position.
Mold Opening and Side Action Retraction
The mold starts its opening sequence by having side actions move backward before it opens. It protects both the part and molds during their removal sequence. The precise timing of mold opening and side action movement determines operational efficiency and exact cycle control.
Types of Injection Mold Side Actions
Selecting the right type of side action can reduce the cost of tool administration and save time. Different side actions have distinct benefits, making it convenient to fabricate custom types for every task.
Cam-Driven Side Actions
Side actions controlled by cams represent the most widespread mechanisms in injection molding operations. A mechanical cam system operates through the side-core movement. The mold closure triggers the cam pin to enter a slot on the moving side core. It then pushes the cam to generate intricate mold features. The system operates with exceptional efficiency which makes it ideal for manufacturing large quantities.
A simple design of the cam often leads to dependable operation and affordable implementation. These systems do not require a constant supply of power such as hydraulics or pneumatics. For a smaller mold design, cams are best for molding side action to create holes or grooves without compromising on part quality.
Cam Driven Side Actions deliver optimal results when the part design follows the natural movement of the cam. Maintaining proper alignment with regular lubrication combined with ongoing maintenance ensures mold performance consistency, and protects equipment from damage due to time-related wear.
Lifters
Lifter side actions enable the production of undercuts and angled features. Such features cannot be achieved with typical molding side actions. In general, side actions move in a straight line but lifters achieve both vertical and angular movement. The dual movement capabilities allow lifters to retract from complex features during part ejection so the mold can safely release it.
Lifters consist of a guide pin, lifter rod, and angled insert that works in assembly. The guide pin triggers the lifter rod to move it both upward and outward during mold opening. Once the mold opens, the lifters move to help release the molded part from any angled or undercut areas. Lastly, these return to their starting position when the mold closes after the part has been removed.
In addition, lifters can make designs for internal features and deep grooves in the structure. For a successful operation, exact alignment is needed for the design choice to prevent any type of sticking and damage. Selecting the appropriate tool for the task will enable the manufacturers to maintain the quality of the end product.
Sliders in Injection Molding Side Actions
Sliders are more frequently applied in injection molding applications. These components operate either horizontally or at a predetermined angle to generate features that run perpendicular to the mold opening direction. The slider is usually an integration of a core component that moves within the mold design.
The slider functions through power sources that include cam mechanisms, hydraulic cylinders, and pneumatic actuators. The mold-closing process allows the actuator to drive the slider into position which creates the intended part shape. After plastic solidification, the slider moves backward as the mold opens so the part can be released without any difficulty.
In addition, sliders deliver outstanding precision alongside flexible operation. So, these are perfect for detailed design work. Engineers must conduct precise design work to achieve the right slider motion alongside correct alignment and sufficient force needed to create the part.
Unscrewing Side Actions
Unscrewing side actions serve to mold parts with threaded features including caps, lids, and connectors. These operate through rotation to free-threaded parts during ejection while side actions with traditional designs move either straight or at a slant.
A motorized/mechanical drive system operates the core that is responsible for forming threads. The precise rotation of such systems depends on servo motors, hydraulic motors, and rack-and-pinion systems. The unscrewing core rotates in unison with stationary parts to separate threads before the mold completes its opening motion.
In addition, unscrewing siders helps make complex threaded components yet their implementation requires extra complexity and cost. The mold opening needs to match precisely with core rotation for these mechanisms to function properly.
Collapsible Core Side Actions
Collapsible cores are advanced side actions that enable the production of parts that encompass internal undercuts and complex hollow features like threads and deep recesses. The cores contract internally. When the ejection process starts it allows the molded piece to exit without any shape distortion. Besides, their mechanism removes the requirement for unscrewing procedures and multiple mold components.
During injection molding, the collapsible core’s segmented sections expand outward to create the required internal shape. These segments move back into the mold after the plastic part reaches solidification. The system activates through mechanical, hydraulic, or pneumatic systems.
In addition, the implementation of collapsible cores demands precise engineering work and strict tolerance. Besides, it needs regular maintenance to maintain reliable performance.
