Device for the automatic molding of paste-like, solidifiable products, such as, for instance, cosmetics and the like

Claim 3

A device as set forth in claim 1 in which said mold parts have guide members to facilitate the engagement and separation of said one mold parts from said other mold parts.

Claim 4

A device as set forth in claim 1 in which said last mentioned means includes levers having arms attached to said other mold parts and means for urging said levers in one direction about their pivots to press said mold parts together when said table is in said one position and in another direction about their pivots to separate said mold parts when said table is moved to said second position.

Claim 5

A device as set forth in claim 3 including a cam track, said levers having members in contact with said track, said track being shaped to press one of said levers in said one direction to hold the mold parts together when said table is in said one position and to press said one lever in the other direction to cause the arm of said lever to separate said mold parts when said table is moved to said second position.

Claim 6

A device as set forth in claim 3 wherein the attachment between said arms of said levers includes springs positioned to urge said other mold parts toward said one mold parts thus to provide tight engagement between the two mold parts.

Claim 7

A device as set forth in claim 1 wherein said other mold part constitutes the bottom portion of the complete mold, whereby when said other mold parts are removed the contents of said molds may be removed downwardly from the molds.

Claim 8

A device as set forth in claim 5 including means located below said molds and driven in synchronism with said table for receiving the content of each mold one by one as it comes downwardly from the molds and passing it to another location.

Claim 9

A device as set forth in claim 6 wherein said receiving means includes a tube which is vertically aligned with said mold when said table is in said second position so as to catch said mold contents when removed downwardly from the molds.

Claim 10

A device according to claim 8 wherein said receiving means includes at least one tube retained by a supporT, the rotational axis of which is at right angle to that of the mold and alignable, each time, with said tube; and by driving means to impart to the tube at least two angular positions, to which the opening of said tube is aligned in such a way as to register with the fixed part of the mold and with that of the container and support for the paste.

Claim 11

A device according to claim 6 characterized by a shaft keyed sideways to the paste-carrying tube by a lever fulcrummed to said tube, the ends of which connect, by means of articulated drives, at one side, through a linkwork, to the motor which drives the table and, at the other side, with a spring thrust member provided by said tube, in such a way that, when said lever is actuated, it imparts an oscillating motion to the tube, in order to change the position of said tube from the fixed part of the mold toward the container for the paste and to successively actuate the pushing member for the introduction of said paste into the container.

Claim 12

A device as set forth in claim 10 including means for moving said tube to discharge the mold contents therefrom and to move the tube back again for receiving the contents of the next mold when its parts are separated by said lever moving means.

Claim 13

A device according to claim 6 characterized by supporting means to removably retain containers for the pastes, equipped with means to stop and to retain the free end of the tube for the paste, in alignment with that of the container.

Claim 14

A device according to claim 9 characterized by a rotating drum, rotatable about its own axis and provided, at its periphery, with recesses for the containers for the pastes by actuating means synchronized with the driving means of the paste-carrier tube, to impart a step-by-step motion to said tube by means to introduce into the housings of said drum the supports for the pastes and eventual covers for said supports, such means being associated with at least one container for the supports delivering into said drum by stopping means for the paste-carrier tube provided by the drum and designed to retain said tube in alignment with the axis of grooves when said grooves reach, successively, the top of said drum; and adjustable means provided by the grooves of the drum, to retain the supports for the pastes in the desired position.
