Abstract

A moulding system for moulding a mass with a pasty or dough-like composition, such as a mass of meat, for example for moulding hamburgers, includes a housing having a chamber which is delimited by internal walls of the housing. The chamber emerges on the outside of the housing. A displaceable mould plate, which is formed in a manner corresponding to the chamber, fits with a small degree of play into the chamber and has at least one mould cavity. The housing has a feed opening, which opens into the chamber, for the mass to be moulded, such that, in the position in which the mould plate has been slid into the housing, the mould cavity is in communication with the feed opening and, in the position in which the mould plate has been slid out of the housing, the mould cavity is situated outside the housing. One of the internal walls of the chamber, in the region of the feed opening, has a recess in which a pressure-exerting member is situated, which bears with prestressing against the mould plate in order to provide a good seal and cutting action.

Claims

1. A moulding apparatus for moulding a mass having a pasty composition, comprising:

a housing including a base plate, a ventilation plate and walls;

a chamber defined by the base plate, the ventilation plate and the walls;

a feed opening formed in the base plate and opening into the chamber;

a movable mould plate having at least one moulding cavity, and being movable into the chamber to allow the mould cavity to communicate with the feed opening, and out of the chamber to allow a moulded product to be removed from the mould cavity;

a recess formed in one of the walls, and around the feed opening; and

a pressure-exerting member situated in the recess, and including means for exerting pressure to press the pressure-exerting member against the mould plate to provide a good seal and cutting action.

2. The moulding apparatus according to claim 1, wherein the means for exerting pressure comprise spring elements situated between the pressure-exerting member and the base plate.

3. The moulding apparatus according to claim 1, wherein the pressure-exerting member is situated on a wall of the chamber where the feed opening emerges.

4. The moulding apparatus according to claim 3, wherein the pressure-exerting member has an opening which coincides with the feed opening.

5. The moulding apparatus according to claim 4, wherein the pressure-exerting member is a pressure plate.

6. The moulding apparatus according to claim 5, wherein the pressure plate has a groove, which runs around the opening, on a side remote from the chamber, and an encircling spring element is situated in said groove.

7. The moulding apparatus according to claim 6, wherein the pressure plate has a further groove in which another spring element is situated.

8. A moulding machine for moulding a mass having a pasty composition, comprising:

a container for the mass to be moulded;

pressing means operatively associated with the container for transporting the mass from the container to a moulding system; and

discharge means for discharging a moulded product from the moulding system;

said moulding system comprising;

a housing including a base plate, a ventilation plate and walls;

a chamber defined by the base plate, the ventilation plate and the walls;

a feed opening formed in the base plate and opening into the chamber;

a movable mould plate having at least one moulding cavity, and being movable into the chamber to allow the mould cavity to communicate with the feed opening, and out of the chamber to allow a moulded product to be removed from the mould cavity;

a recess formed in one of the walls, and around the feed opening; and

a pressure-exerting member situated in the recess, and including means for exerting pressure to press the pressure-exerting member against the mould plate to provide a good seal and cutting action.
