Self-holding and self-extracting seal molding system and method
A seal molding system includes a mold body having a mold body inner geometry configured complementary to a fitting outer geometry of a fitting, and a mold collar having one or more mold collar engagement elements configured to engage with one or more fitting engagement elements. The mold collar is couplable to the mold body at a body-collar interface allowing free rotation of the mold collar relative to the mold body. The body-collar interface is configured such that axial motion in a first axial direction and/or rotational motion in a first rotational direction of the mold collar relative to the fitting causes the mold collar to urge the mold body against a panel surface, and axial motion in a second axial direction and/or rotational motion in a second rotational direction of the mold collar relative to the fitting causes the mold collar to draw the mold body away from the panel.

THREADED MOLD DECOUPLING ASSEMBLY
A threaded mold decoupling system comprises a set of unscrewing assemblies, each unscrewing assembly disposed in proximity to a corresponding threaded core of a set of threaded cores and having an unscrewing element defining an unscrewing element circumference and a driving element disposed in operative communication with an unscrewing assembly of the at least one set of unscrewing assemblies. The driving element defines a driving element circumference, a ratio of the driving element circumference to the unscrewing element circumference defining a number of rotations of each unscrewing element relative to a number of rotations of the driving element. The driving element is configured to rotate each unscrewing element in a first direction between a first position and a second position to decouple each threaded core from a corresponding molded article and in a second direction between the second position and the first position to reset each unscrewing assembly.
Injection-moulding machine with an index shaft having a channel for a fluid
An injection-moulding machine, having a first platen, which is designed for carrying a first mould half of an injection mould, a second platen, which is designed for carrying a second mould half of the injection mould in such a way that in a closed state of the injection mould the first mould half and the second mould half delimit at least one cavity of the injection mould, and having an index shaft, which is mounted rotatably and axially adjustably on the injection-moulding machine outside the injection mould, is rotationally driven by of a motor of the injection-moulding machine arranged outside the injection mould and has an end portion which protrudes into the injection mould in the installed position of the injection mould in the injection-moulding machine, is designed for fastening on the index shaft an index plate to be arranged within the injection mould and has at least one channel which is designed to feed a fluid to the index plate or to remove a fluid from the index plate, wherein by means of the index shaft, driven by the motor, the index plate is automatically adjustable between a first plate position of the index plate and at least one second plate position of the index plate, and wherein the motor has a hollow motor shaft, through which the fluid is passed.
INSERT MOLDING APPARATUS
An insert molding apparatus includes: a lower mold including a seating part on which an insert member including a through-hole is seated; an upper mold mounted on the lower mold to receive the insert member seated on the seating part; and a first fixing part including a first head provided in the lower mold and inserted into the through-hole of the insert member when the insert member is seated, and a first drive unit that moves the first head. The first drive unit is moved to adjust a length by which the first head is inserted into the through-hole.
Method for producing a double walled drinking vessel
An injection mold for producing a double walled drinking vessel includes first and second mold portions. The first mold portion forms a first and second cavities corresponding to the outer shape of the outer container and the outer shape of the inner container, respectively. The first and second cavities are located concentrically with respect to a central axis. An index plate is rotatable and axially movable along the central axis relative to the first mold portion. The index plate includes a first core and a second core. The first cavity has a first cavity injection gate for injecting mold material into the first cavity for forming the outer container. The second cavity has a second cavity injection gate for injecting mold material into the second cavity for forming the inner container. The first cavity has a further injection gate for injecting joint material for joining the outer and inner containers.
PLASTIC FAUCET BODY AND A DIE FOR MOLDING THE SAME
The invention discloses a plastic faucet body and a molding tool thereof. The faucet body includes a left water inlet pipe (1) and a right water inlet pipe (2), wherein a left valve seat installation recess (11) is formed in the left water inlet pipe (1) and a right valve seat installation recess (21) is formed in the right water inlet pipe (2). A connecting cross-beam (3) is disposed between the left water inlet pipe (1) and the right water inlet pipe (2), wherein the connecting cross-beam (3) is provided with a water outlet (31) and a middle water channel is formed within the connecting cross-beam (3).
