Processing & Inspection Machine List.pdf
Core pins are used primarily in the plastic molding and die casting applications. In most cases core pin are fixed in the plastic mold and are used to create a desired shape in the molded or cast part. Unlike the purpose of a an ejector pin which is pushed or extended by the ejector plate to eject the cooled molded or cast part from the cavity/core. It is often easier to machine a core pin as a separate element and add it to the A-side or B-side of the mold as needed. Core pins are sometimes used in aluminum molds to create tall, thin cores that might be too fragile if machined out of the bulk aluminum of the mold. In some applications core pins are also used for part ejection from a casting die.
There are many types of pins with in mold bases and die casting molds. Each are designed (based on material type, core and surface hardness, and coatings) for different applications within the molding or casting process. Many factors need to be considered to choose the correct pin for the application. Factors like the draft and texture of sidewalls, depth of walls and ribs can increase the likelihood that areas of the part will cling to the mold. Resin choice can also affect pin placement or size. Some resins are “stickier,” requiring more force for release from the mold. Softer resins may also require the use of more or bigger pins to spread the force and prevent puncturing or marring of the cooled plastic.

FAQ:
Q1: What is a core pin in molding?
Core pins are used in the plastic molding and die casting dies. They are a fixed element used to create a void providing the desired shape in the molded or cast part. It is often easier to machine a core pin as a separate element and add it to the A-side or B-side as needed.
Q2: What is a core in a mold?
A core is a preformed, bonded, sand insert placed into the mold to shape the interior of a casting or a part of the casting that cannot be shaped by the pattern. Cores are frequently used to create hollow sections or cavities in a casting.
Q3: What is the difference between die and punch?
A: During sheet metal forming, two different parts may be used. One part is called the punch. It performs the stretching and bending or blanking operation, while the other part is called the die block. It securely clamps the work piece and provides similar stretching bending or blanking operations.
Q4: How does a die punch work?
A: The action of a Punch & Die uses a solid metal piece, the “Punch” located vertically above the “Die”. The Die corresponds in size and shape to the Punch and is secured directly beneath the Punch. The Punch is usually, hydraulically driven to meet the Die.
Q5: How many types of die are there?
A: Combination dies are used for operations involving more than one operation on a work station. The major difference between compound dies and combination dies is that in these dies a cutting operation is combined with with a bending or drawing operation, and hence the name “combination dies”.
Q6: What are punch dies made of?
A: Punch tooling (punch and die) is often made of hardened steel or tungsten carbide. A die is located on the opposite side of the workpiece and supports the material around the perimeter of the hole and helps to localize the shearing forces for a cleaner edge.
