Receptacle with mount feature
View Patent ↗A method for forming a receptacle may include providing a mold having a forming surface and a recessed area defining part of the forming surface, the mold having sections that may be separated to open the mold and closed together to close the mold. A molten plastic parison may be provided into the mold when the mold is open, the mold may be closed and the parison may be expanded against the forming surface so that a portion of the parison enters the recessed area. The portion of the parison within the recessed area may be formed by moving a secondary forming feature relative to the mold and parison to define a mount feature.
1. An apparatus for forming a molded receptacle, comprising:
a mold having mold sections movable between two positions to define an open position of the mold and a closed position of the mold, defining a forming surface against which the receptacle is formed, and having a recessed area that defines part of the forming surface;
a secondary forming feature carried by at least one of the mold sections and having a body movable relative to at least one mold section and having a head that defines part of the forming surface of the mold against which a portion of the receptacle is formed, the head facing the recessed area and movable from a first position retracted from the recessed area and a second position advanced adjacent to the recessed area to form a portion of the receptacle; and
a pin carried by the secondary forming feature, the pin being movable relative to the body between a first position and a second position wherein an end of the pin extends beyond the body, wherein the secondary forming feature includes a housing carried by a mold section, an actuator that moves the body relative to the mold section to which the housing is fixed and is carried by the housing, and a second actuator that moves the pin relative to the body and wherein said second actuator is carried by the housing.
2. The apparatus of claim 1 wherein the head includes a connection feature open to the exterior of the body and adapted to receive a portion of the material from which the receptacle is molded to connect the body to said portion of the material.
3. The apparatus of claim 2 wherein said portion of the material defines scrap material and movement of the body away from its second position toward its first position carries at least some of the scrap material with the body away from the recessed area.
4. The apparatus of claim 1 wherein the body includes a passage in which the pin is received.
5. The apparatus of claim 1 wherein the secondary forming feature includes a housing and the housing is fixed to a mold section.
6. The apparatus of claim 5 wherein the secondary forming feature includes an actuator that moves the body relative to the mold section to which the housing is fixed, and the actuator is carried by the housing.
7. An apparatus for forming a molded receptacle, comprising:
a mold having mold sections movable between two positions to define an open position of the mold and a closed position of the mold, defining a forming surface against which the receptacle is formed, and having a recessed area that defines part of the forming surface;
a secondary forming feature having a housing fixed to at least one of the mold sections and having a body movable relative to at least one mold section and a pin also movable relative to at least one mold section, the body having a head that defines part of the forming surface of the mold against which a portion of the receptacle is formed, the head facing the recessed area and movable from a first position retracted from the recessed area and a second position advanced adjacent to the recessed area to form a portion of the receptacle, and the pin being movable relative to the body;
an actuator to move the body and wherein the actuator is carried by the housing, and an actuator to move the pin and wherein the actuator is carried by the housing.
8. The apparatus of claim 7 wherein the housing is fixed to a mold section by mechanical fasteners.
