Abstract
A stripper plate locking device for use with the mold in a molding machine (e.g., injection, compression or transfer) is presented. The mold has openings in each of the plates of the mold for accepting the stripper plate locking device. The device includes a release pin, a body member and a collet member. The pin has a shaft with a head disposed at one end and a first pair of camming surfaces with a shaft portion therebetween disposed at the other end. The body members has a second pair of camming surfaces with a cylindrical portion therebetween disposed at one end thereof and an opening therethrough wherein the shaft of the pin passes. The collet member has a plurality of expandable resilient fingers which define an opening. The collet member includes a third pair of camming surfaces with a first cylindrical section therebetween for expanding the fingers in cooperation with the first camming surface and the shaft portion of the pin. The collet member also has a fourth pair of camming surfaces with a second cylindrical section therebetween. The cylindrical portion is retained at the second cylindrical section when the fingers are in a nonexpanded position and is released when the fingers are expanded.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
