dip angle of angle pin in the core-pulling mechanism of a mold
The size of dip angle is not only related with the bending force of angle pin and the actually realized pulling force but also connected with the working length of angle pin, […]
Your mold shop should plan workholding
Planned workholding, in its simplest form, is planning in advance how the workholding will be accomplished prior to the job getting to the machine. In the more complex form, all workholding for each machine is planned at the design stage with documentation that will provide the plan for the workholding at each operation. Planned workholding [...]
New injection simulation softwares are getting advances
High quality plastics components are becoming an increasingly important part of the perceived quality of products. An important part of this high quality perception is a flawless and often high gloss surface finish. Traditional methods such as surface coatings and other secondary operations are often expensive and impractical for high-production volumes. In many cases, the [...]
New CAD technology change design ideal
Technology—including CAD technology—has changed dramatically since the 1980s. As soon as new technology is developed, it is integrated into products and our way of doing business. In the manufacturing world, CAD software versions are released at regular intervals with product design and manufacturing processes integrating the new CAD technology as soon as it becomes available. [...]
How to improve surface finish in CNC machine cutting
Surface finish problems can be profit killers for today’s mold manufacturer. One of the most common causes is chatter created by vibration in the CNC machine tool cutting process. This can lead to higher costs, delayed deliveries and even lost orders due to poor quality. In addition, vibration can cause uneven tool wear, resulting in [...]
Side core-pulling mechanism drived by spring in mold
When the side concave of plastic parts is shallow and requires relatively smaller pulling force, spring or ebonite can be used to achieve core-pulling.
Power-driven core-pulling in mold
Such mechanism pulls out the active cores by utilizing the mold opening force of injection machine and through the driving of parts. […]
Hydraulic or Pneumatic Core-pulling in mold
Use pressure oil compressed air as power, equipped the molds with special hydraulic or pneumatic tank, […]
Manual pulling in mold
Manual pulling refers to the pulling of side-direction cores with hand or hand tools. Such mechanism is simple in structure yet low in productivity and large in labor intensity.
what is core-pulling mechanism
the flanks of plastic parts are usually provided with holes or flutes, under such cases, side-direction forming cores must be employed to form plastic parts. […]
