Abstract

Disclosed herein, amongst other things, is a method of transferring a molded article from a moveable mold half of a mold into a receptacle of a post-mold tool. The method includes positioning the moveable mold half relative to the post-mold tool to position the molded article thereon closer to the receptacle and retracting the moveable mold half while simultaneously extending a stripping device to eject the molded article from the moveable mold half and to transfer it into the receptacle.

First claim

What is claimed is:

1. A molding system comprising:
a moveable platen comprising:
a moveable mold half, and
a stripping device;

a platen actuator linked to the moveable platen;
a post-mold tool comprising:
a receptacle;

a carrier actuator linked to the post-mold tool;
a controller including a controller-usable memory, the controller-usable memory storing instructions for controlling the molding system, the instructions being for controlling the molding system to transfer a molded article from the moveable mold half of a mold into the receptacle of the post-mold tool, the instructions, when executed, causing:
positioning of the moveable mold half relative to the post-mold tool to position the molded article thereon closer to the receptacle, wherein the positioning further includes:
controlling the platen actuator to reposition the moveable platen of the molding system away from a stationary platen of the molding system to separate the moveable mold half from a stationary mold half of the mold that are mounted thereto, respectively; and
controlling the carrier actuator to position the post-mold tool into the receiving position that is between the moveable mold half and the stationary mold half to align the receptacle with the molded article on the moveable mold half;
controlling the platen actuator to position the moveable platen on which the moveable mold half is mounted to cause insertion of the molded article into the receptacle; and

controlling the platen actuator to reposition the moveable platen to cause retracting of the moveable mold half while simultaneously extending the stripping device to eject the molded article from the moveable mold half and to transfer it into the receptacle.

2. The molding system of claim 1 , wherein the instructions, when executed, cause the retracting the moveable mold half while simultaneously extending the stripping device of the moveable mold half to eject the molded article from the moveable mold half into the receptacle by:
controlling the platen actuator to move the moveable platen away from the post-mold tool and thereby retract the moveable mold half away from the post-mold tool while simultaneously controlling an ejector actuator to extend the stripping device to eject the molded article from the moveable mold half into the receptacle.

3. The molding system of claim 2 , wherein the instructions, when executed, control the platen actuator and the ejector actuator to extend the stripping device with substantially equal and opposite movement to retraction of the moveable mold half such that the stripping device remains substantially stationary relative to the post-mold tool as it ejects the molded article from the moveable mold half.

4. The molding system of claim 3 , wherein the instructions, when executed, further cause:
the ejector actuator to retract the stripping device once the molded article has been ejected from the moveable mold half.

5. The molding system of claim 4 , wherein the instructions, when executed, further cause:
the platen actuator to reposition the moveable platen away from the post-mold tool to withdraw a core insert of a core assembly from the molded article—that is resident in the receptacle.

6. The molding system of claim 5 , wherein the instructions, when executed, further cause:
the carrier actuator to withdraw the post-mold tool to a transfer position with the molded article in the receptacle.

7. The molding system of claim 6 , wherein the instructions, when executed, further cause:
an ejector to eject the molded article from the receptacle.
