Description

Mold, extrusion and dumpling machine

The present invention relates to a mold for producing dumplings, a pressing device for driving the mold to produce a pressing action, and a dumpling machine provided with the above mold and pressing device.

Modern dumpling food manufacturers mostly use dumpling machinery to improve production efficiency. Most of the existing dumpling machines package dumplings in the following manner: First, a dough or a surface water mixture is rolled into a dough sheet having a desired quality and a predetermined thickness by a rolling mill; A die cutter having a predetermined geometric cross section is punched from the dough to a dough having a corresponding geometric shape (for example, a circular or elliptical shape), and the cut dumpling is flattened. The posture is synchronously dropped into the forming fixture located under the punching knife; finally, the dumplings carried on the mold and moving along with the mold are filled with the filling at the subsequent station, and are replaced by the closing action of the mold. The clip is made into a semi-finished dumpling that is roughly "D" shaped or semi-circular. The above process is fully described in the patent application (No. 98127991) entitled "Dumpling Making Method and Manufacturing Equipment" filed by the applicant on August 20, 2009.

In the subsequent process, the "D"-shaped or semi-circular dumplings and semi-finished products are further hand-kneaded by humans into hand-made dumplings having a desired shape. The above manual kneading is usually carried out in the following manner: First, the worker holds the entire curved edge of the dumpling semi-finished product as much as possible with the thumb and forefinger of both hands (hereinafter referred to as "dumpling crown"); then, by closing the two-handed wrists inwardly The thumb and the index finger in the pinch state are used to squeeze the stuffing sac of the dumplings on the surface of the finger on the palm side and the partial surface in the palm (commonly known as "dumpling belly"). After the above extrusion, the outline of the dumplings evolved from a generally "D" shape or semi-circular shape in the semi-finished product to a typical hand-made dumpling shape, for example, to a scallop shape or a curved triangle. The extruded dumplings are compact and juicy, which is more in line with the taste of consumers. Of course, it can be understood that depending on the details of the worker's tactics, there are still individual differences in the contours of the final formed dumplings, but the common feature is that the stuffing sac of the dumplings has been manually squeezed in the above manner.

However, in the prior art, the above-mentioned kneading process has to be completed by humans, and the machine is currently not replaceable. This situation has been constraining the further increase in productivity in the industry. According to statistics, depending on the efficiency of the machine, a full-loaded dumpling machine needs at least 5 to 6 skilled workers to achieve the flow operation, and the labor cost is considerable.

In order to finally realize the full automation of the dumping process, the present invention provides a forming mold for making dumplings or dumplings, the mold comprising a pair of clips, and the pair of clips can be closed to form dumplings filled with stuffing into dumplings. The shape of the semifinished product. In the closed state, the folder can simulate the action of the human hands to squeeze the dumpling filling bag from the dumpling crown in the plane in which it is driven by the external force. After the above extrusion, the overall outline of the final shaped dumplings evolves from a "D" shape or a semi-circular shape in the semi-finished product to a shape closer to the purely hand-made dumplings, and the extruded dumplings are compact and juicy. More in line with consumer taste preferences. The adoption of the above-mentioned molds completely replaces the existing traditional pattern of hand-made dumplings in the food industry, which not only greatly increases productivity, but also reduces labor costs.

The present invention also provides a pressing device for driving the above-mentioned mold action, which can drive the pair of clips along their own by applying an external force in a state where the pair of jaws of the mold are in a closed state. The plane is used to simulate the action of human hands from the dumpling crown to squeeze the dumpling filling sac.

The present invention also proposes a dumpling machine comprising the above mold and extrusion device.

The objects, features, and advantages of the invention will be apparent from the description of the appended claims.

It is first stated that the term "dough" or "face water mixture" as used in the present invention refers to a mixture of milled grains (including flour, rice flour, etc.) and liquids (including: water, milk, fat, etc.) of various cereals. As a raw material for the production of food (especially dumplings or dumplings). The meaning is not limited to a mixture of wheat flour and water that is conventionally understood. Therefore, any of the above raw materials can be used to produce the dumplings or dumplings of the present invention as long as it has practical significance in production practice.

In addition, the names of "dumplings", "dumplings", and "dumplings" as described in the present invention are not limited to foods such as "dumplings" and "dumplings" in traditional Chinese foods, but also include Japanese dumplings and Russian style. Semi-circular dumplings (pierogi), Italian ravioli, and other kinds of dumplings. In summary, any equipment or method that attempts to simulate or replace human hand-made dumplings by machine technology, as long as it involves the use of movable mold parts to simulate the hand-packing of the dumplings of the dumplings, should be included in the present invention. The scope of protection.

In addition, for the convenience of description, whether it is the semi-finished dumplings or the finished finished dumplings, the edges of the dumplings which are bonded to each other due to the opposite folding (ie, the "D" shape or the semi-circular dumplings semi-finished products The curved edges are referred to herein as "crests". In addition, the portion that bulges outward due to the inclusion of the filling, commonly known as "dumpling belly", is referred to herein as a "filling pocket." Therefore, the dumplings of the present invention, whether finished or semi-finished, are composed of a filling sac that is bulged outward in the middle and a curved dumpling crown other than the filling sac.

Finally, the directional descriptions of "front", "back", "left", "right", "upper", "lower", etc. appearing in the present invention and its drawings are only used to indicate that the product is in the specific embodiment and Specific orientations in the figures. The above-mentioned reference to the direction is based solely on the particular reference frame selected in the drawings, and is for the purpose of convenience of description, and is not intended to be absolute or for any limitation. In other words, any understanding of the invention should not be limited to the particular reference frame selected above for the particular orientation.

In the embodiment illustrated in FIGS. 2-4, the forming pallet 100 includes, in order from top to bottom, at least one pair of molds 10, a corresponding number of transmission mechanisms 20, a chassis 30, and a base 50. Each of the molds 10 includes two pieces of symmetrical shapes 11 and 12. When the two sheets 11 and 12 are flattened, the mold 10 is completely opened. At this time, the overall contour of the mold 10 is substantially the same as the shape of the dumpling. Since the conventional dumplings are mostly circular or elliptical, in the present embodiment, the peripheral contour of the mold 10 in the fully opened state is correspondingly substantially circular or elliptical. Of course, in order to adapt to different shapes of various types of dumplings, the mold 10 can also adopt other shapes in design, such as diamonds or rectangles, as long as it has practical significance in production practice. The forming unit 100 may also include only one pair of molds or two or more pairs of molds.

As shown in FIGS. 5 and 6, in addition to the jaws 11 and 12, the mold 10 further includes a sauser 35. The tray 35 is used to receive the dumplings punched out by the punching knife together with the jaws 11 and 12 in a state where the mold 10 is fully opened. As the forming unit 100 continues to travel along its predetermined route or sequentially in different working positions, the jaws 11 and 12 can be gradually closed under the drive of an external force, and are similar to the action of closing the double shell, and finally filled with the filling material. The dumpling wallet is made into a semi-finished dumpling that is roughly "D" shaped or semi-circular.

In the embodiment shown in Figures 2-4, the jaws 11 and 12 are preferably constructed of an elastic material (e.g., rubber and various elastomers) and passed through connectors 40a and 40b (e.g., pins, bolts). , nails, etc., see Figure 4) connected to the transmission mechanism 20. In the present embodiment, the connecting members 40a and 40b are schematically constituted by pins whose upper ends are respectively fitted into the inside of the jaws 11 and 12 from below, so that the jaws 11 and 12 and the swinging member 22b of the transmission mechanism 20 (post Detailed description) Reliable connection. As a result, each of the stacks 11 or 12 can be swung within a predetermined range along the plane in which the swinging member 22b is located. It is necessary to point out that the clip "the plane in which it is located" (hereinafter sometimes referred to as "the plane in which the clip is located") refers herein to the imaginary plane defined by each clip based on its shape. For example, in the case shown in FIG. 3, the plane in which the folder 11 itself is located refers to an imaginary plane defined by the "D" shape or the semicircular contour of the magazine 11; the plane in which the folder 12 itself is referred to is the folder An imaginary plane defined by a "D" or semi-circular outline of 12. In a state where the jaws 11 and 12 are sufficiently flat or completely closed, the plane in which the jaws 11 are located substantially coincides with the plane in which the jaws 12 are located. That is to say, in a flat or closed state, the pair of jaws 11 and 12 together define the same plane.

In the embodiment illustrated in Figures 3-6, the transmission mechanism 20 is illustratively a four-bar linkage wherein the connector 40a further extends through the V-shaped member 22 of the four-bar linkage, the lower end It is fixed to the wing plates 34 of the underpan 30. If the four-bar linkage is deformed by the external force, the V-shaped member 22 is pivoted by the connecting member 40a. As a result, the swing arm 22b of the V-shaped member 22 swings the jaws 11 and 12 together by the connecting member 40b. In the present embodiment, as the swinging member of the transmission mechanism 20, the swing arm 22b of the V-shaped member 22 is used to drive the jaws 11 and 12 to simulate the action of squeezing the dumpling filling pouch by the human hand in the closed state.

As shown in Figs. 2-5, the inner surfaces of the jaws 11 and 12 which are in contact with the dumpling skin after being closed are further provided with recesses 13. The recessed structure 13 can be a wedge-like notches or other types of grooves. When the jaws 11 and 12 are swung inwardly along with the swinging member 22b of the transmission mechanism 20, the position corresponding to the recessed structure 13 thereon will be similar to the flexion (flexes) when the human finger joint is bent. ) and creases. In a state in which the pair of jaws 11 and 12 are closed, the buckling and the wrinkles cause the dumplings formed by the pair of jaws to have a similar appearance to the touch of the human finger joint, thereby finally The shaped dumplings have a high degree of artificial hand-made dumplings, which is more in line with the aesthetic preference of traditional hand-made dumplings.

In order to enable the jaws 11 and 12 to reliably return to their original home position in the uncompressed state by their own elasticity after performing the squeezing action, it is preferable to further enhance the elasticity of the jaws 11 and 12. To this end, the elastic member 14 may be added inside the jaws 11 and 12. As shown in FIG. 4, the elastic member 14 may be in the form of a twisted metal embedded in the inside of the jaws 11 and 12. Obviously, other types of elastic members, such as metal bars, plate springs, etc., can also be suitably employed. To fully utilize the elastic performance of the elastic member 14, it is also possible to further traverse the elastic members 14 inside the jaws 11 and 12 through the ends of the connectors 40a and 40b. With this design, the elastic force of the elastic member 14 can directly act on the four-bar linkage mechanism 20 through the connecting members 40a and 40b, thereby contributing to the improvement of the service life of the clip made of the elastic material. Alternatively, the elastic member 14 may be disposed on other members having a connection relationship with the jaws 11 and 12 outside the jaws 11 and 12, for example, in the four-bar linkage mechanism 20. This program will be explained later.

In the embodiment shown in FIG. 4, the four-bar linkage mechanism 20 is illustratively a rod-hinged mechanism in which two linear links 21 and two V-shaped members 22 are hinged to each other. Wherein, the two linear links 21 are V-shaped end-hinged, and a cam roller 23 is disposed on the hinge shaft between the two; the other end of the linear link 21 is diverged They are hinged with the side arms 22a of the V-shaped member 22, respectively. Through the above connection, the two linear links 21 and the side arms 22a of the two V-shaped members 22 together constitute a quasi-parallelogram mechanism of the four-bar linkage mechanism 20.

As described above, as the swinging member of the four-bar linkage mechanism 20, the swing arm 22b of the V-shaped member 22 directly acts on the jaws 11 and 12 through the joint members 40a and 40b. As shown in Figures 4-6, the connector 40a is further secured to the underlying wing 34 by the V-vertex position of the V-shaped member 22 such that the V-shaped member 22 can pivot about the link 40a. Turn. With the above structure, the four-bar linkage mechanism 20 can drive a pair of jaws 11 and 12 as a simulated human hand to squeeze the dumpling filling capsule based on the parallelogram deformation transmission principle. More specifically, if an external force acts directly on the four-bar linkage mechanism 20 via the roller 23, the four-bar linkage mechanism 20 is deformed by the force, thereby causing the swinging member 22b to swing in a predetermined range along the plane in which the jaws are located. In a state where the jaws 11 and 12 are closed, if the four-bar linkage 20 is gradually "short" due to the force, the swinging member 22b is pivoted along the plane of the jaws 11 and 12 with the connecting member 40a as a pivot. The inside of the mold 10 is swung, thereby causing the pair of jaws 11 and 12 in the closed state to gather inwardly in a plane of their own to be substantially "Ω" or "C". The dumplings extruded in this way generally approximate the scallop shape.

As another way of simulating a human hand squeezed dumpling filling pouch, the position of the connecting member 40a as a pivot can also be transferred from the V-shaped vertex position of the V-shaped member 22 to the side arm 22a of the V-shaped member 22, There is a certain distance from the V-vertex position of the V-shaped member 22. At this time, as long as a connecting member 40b is added at the initial removal position of the connecting member 40a (corresponding to the V-vertex position of the V-shaped member 22) for making up for the vacancy left after the displacement of the connecting member 40a, it is still possible. The respective portions of the jaws 11 and 12 are fixed to the V-vertex position of the V-shaped member 22. In this manner, the entire swing arm 22b and the partial side arm 22a of the V-shaped member 22 will directly participate as the swinging member in the swinging motion of the drive jaws 11 and 12. Driven by such a swinging member, the jaws 11 and 12 in the closed state will collapse inwardly along the plane in which they are located into a substantially rounded "V" shape. The dumplings extruded in this way are roughly curved sides.

Moreover, the specific shape of the swing arm 22b of the V-shaped member 22 can be further changed, for example, from a substantially straight shape as shown in FIG. 3 to a circular arc shape so as to be in conformity with the actual shape of the jaws 11 and 12. . The above changes can adjust the angle and direction of the dumplings filling the sacs of the dumplings 11 and 12 inwardly along the dumpling crown to some extent, thereby helping to further improve the squeezing effect on the filling sac.

In order to make the appearance of the dumplings more realistic, a larger number of concave structures 13 can be added to the jaws 11 and 12, so as to simulate the buckling and wrinkles formed when more fingers are bent. Moreover, the relative position of the concave structure 13 between the two clamping jaws 11 and 12 can be intentionally staggered so that the positions of the concave structures of the two clamping jaws 11 and 12 in the closed state do not overlap each other, so that the human can be simulated. The situation when the finger joints are interlaced. In addition, in order to make the appearance of the final shaped dumplings more diverse, it is also possible to use different forms of sandwiches in different molds to simulate the diversity of the hand-made dumplings.

As previously mentioned, in order to enable the jaws 11 and 12 to reliably return to their original home positions in the non-extrusion state after performing the squeezing action, it is also conceivable to arrange the elastic member 14 in the four-bar linkage mechanism 20. As an embodiment (not shown), the resilient member 14 may be a coil spring disposed between the opposing two hinge shafts 24 (see FIG. 4) of each of the four-bar linkages 20. When the four-bar linkage 20 is forced to deform, the coil spring 14 is also stretched or compressed to store energy. When the external force causing the deformation of the four-bar linkage mechanism 20 is weakened until it disappears, the coil spring 14 releases the energy in a timely manner to cause the four-bar linkage mechanism 20 to drive the clamp jaws 11 and 12 to each return to the original position. It is apparent that the coil spring 14 as the elastic member, if provided in the four-bar linkage mechanism 20, not only contributes to simplifying the internal structure of the jaws 11 and 12, but also ensures that the jaws can be reliably reset after performing the squeezing action. .

In the above embodiment, the deformation of the four-bar linkage mechanism 20 is based on the "rail-guided transmission" between the roller 23 and the pressing guide rail 4 (see Fig. 1, which will be described in detail later). The clamps 11 and 12 are driven. Obviously, for the purpose of the present invention, any other transmission mechanism, such as a planar mechanism, a parallelogram linkage, a crank linkage, a composite linkage, or the like, or other forms of drive A drive means, such as a pressure fluid device (including a hydraulic or pneumatic transmission), as long as it can drive the jaws 11 and 12 to simulate the human hand squeezing the dumpling filling sac from the dumpling crown in their respective planes. Both can be used as a pressing device for driving the mold.

In the case of a fluid pressure device, pressurized fluid inside the device is utilized to drive the jaws. For example, a cavity (hydraulic chamber or air bag) may be provided in at least a portion of the jaws 11 and 12, and the cavity may expand by increasing the pressure of the fluid inside the device in a state where the jaws 11 and 12 are closed. After squeezing out from the surface of the folder that is in contact with the dumpling skin after the closure, the action of squeezing the filling sac inward along the dumpling crown is simulated. After the pressure of the fluid is reduced, the cavity retracts into the interior of the jaws, thereby no longer squeezing the filling capsule. It is necessary to point out that even in the case where the fluid pressure device is employed, the clips 11 and 12 do not have to be entirely made of an elastic material as a whole, as long as the cavity can expand and contract with the fluid pressure. . It can be seen that in order to drive the clamp to simulate the action of squeezing the filling sac, it is suitable for those skilled in the art to select any extrusion device and extrusion means in the prior art, and is not limited to the specific implementation of the present invention. The best way to use it in the example.

As shown in FIGS. 5-6, in addition to the side flaps 34 provided with the rollers 34a, respectively, the chassis 30 also includes pivot discs 31, pivot brackets 32, spacers 33 and trays 35. The two pairs of turntables 31 are opposite each other, and the imaginary connection between the centers of the two forms a hinge axis in which the two side flaps 34 are coaxially opened and closed with the pair of jaws 11 and 12. Specifically, the swivel 32 integrally fixed to the flap 34 must be rotatable along the circular orbit formed by the peripheral flange 31a of the turntable 31. As a result, the flaps 34 can be coaxially opened and closed with the jaws 11 and 12 to perform an action similar to a butterfly flapping a wing. The spacer 33 (see Fig. 2) is used to retain the swivel 32 and thus defines its lowest position when the flap 34 is swayed. When the flap 34 is in the lowest position, the jaws 11 and 12 are substantially flat. The tray 35 fixed to the chassis 30 projects to the center of the mold 10, thereby constituting a part of the mold 10 for carrying with the jaws 11 and 12 for carrying the cut-out of the dumplings and then being filled. Stuffing.

As shown in Fig. 2, the chassis 30 is further fixed to a base frame 50 for carrying the entire forming unit 100 in a controlled manner along the unit rail 1 in a predetermined direction or process position. In the embodiment shown in Figure 1, the unit rail 1 is a linear guide. The forming unit 100 can achieve precise movement and positioning on the unit rail 1 by a conventional transmission method such as a servo motor, a timing belt, a chain, or a pressure fluid device such as a rod-less hydraulic or pneumatic cylinder. In the prior art, the unit rail 1 is often a toroidal rotary rail, so that it is also possible to drive the forming unit 100 on the unit rail 1 by using a central rotating electrical machine in conjunction with a corresponding reduction mechanism.

The operation of the mold of the present invention and its extrusion apparatus will be described in detail below with reference to FIG.

When the forming unit 100 is in its starting position on the right side in FIG. 1, the side flaps 34 of the chassis 30 are resisted by the spacers 33 at the lowest position due to their own weight. At this time, the two sheets 11 and 12 are substantially flat, so that the mold 10 is opened in a substantially dish shape. As explained above, the flat jaws 11, 12 and the tray 35 are used to carry the dumplings to be dropped and the fillings to be filled later. In the case where the conventional dumping machine mostly uses the rotary unit guide rail 1, the forming unit 100 first receives the dumpling skin at a certain starting position of the rotary unit rail 1, and then travels along the guide rail 1 to the next working position, The filling device places the filling in the center of the dumpling skin.

As shown in Fig. 1, as the forming unit 100 advances along the unit rail 1 in a predetermined direction (from right to left in Fig. 1), the rollers 34a (see Fig. 2) continue along the closing rails 2 defining the three-dimensional geometric path, respectively. Upward, thereby driving the side flaps 34 of the chassis 30 and the four-bar linkage 20 above the flaps and the pair of jaws 11 and 12 are simultaneously raised. Thereafter, the two jaws 11 and 12 are completely closed when transitioning from the closing rail 2 to the clamping rail 3. The clamping rail 3 is used to define a path when the roller 34a continues to travel, so that the jaws 11 and 12 continue to clamp the dumpling crown in the closed state, ensuring that the filling that has been enclosed in the filling capsule is subsequently squeezed. It will not overflow during the pressing process.

Shortly after the roller 34a enters the clamp rail 3, the pair of clamps 11 and 12 that have been closed are brought into contact with the squeeze rail 4 by the lifted roller 23. As shown in Fig. 1, the pressing rail 4 is a pair of parallel rails of exactly the same shape. Along the predetermined direction of travel of the forming unit 100, the front half of the pressing rail 4 has a downwardly convex or descending track lower edge for guiding and progressively pressing the roller 23, thereby forcing the four-bar linkage 20 to be progressively subjected to Drive deformation. After the rail-type matching of the pressing guide rail 4 and the roller 23 is transmitted by the deformation of the four-bar linkage mechanism 20, the swinging member 22b is finally converted into the swinging member 22b to drive the pair of clips along the state where the clips 11 and 12 are closed. The plane simulates the action of the hand to squeeze the dumpling filling sac from the dumpling crown.

As the roller 23 passes the lowest point of the lower edge of the pressing rail 4, the lower edge of the second half of the pressing guide 4 exhibits a gradually rising profile. However, just after the roller 23 enters the gradually rising rear half path of the pressing rail 4, the roller 34a of the one side flap 34 is first guided from the clamping rail 3 into the release rail 5. Similar to the closed rail 2, the release rail 5 also defines a travel path having a three-dimensional geometry. Under the guidance of its own weight, the one side flap 34 will gradually sway along the release rail 5 from the ascending state to the lowest position in its flattened state. At this time, the flap 34 on the other side is still kept in contact with the clamp rail 3 on the corresponding side by its own roller 34a, and thus remains in an upright state. In the state in which the current mold 10 is opened on one side, a pusher (not shown) pushes the finally formed dumplings out of the mold 10 and releases them to the side of the running belt, thereby finally completing the machine simulation of the hand-made dumplings. The whole process.

After the one side roller 23 enters the release rail 5 and the other side roller 23 enters the second half of the ascending path of the pressing rail 4, the jaws 11 and 12 made of an elastic material can be elasticized by themselves (preferably, By means of the elastic member 14) it is automatically returned from the compressive position in which the filling capsule is squeezed to the home position corresponding to the position of the edge of the dumpling. Thereafter, the forming unit 100 can return (from left to right) along the original path of the unit rail 1 shown in Fig. 1 up to the starting position on the right side in the drawing. In the case of the prior art carousel guide, the forming unit 100 will re-enter the starting position after a one-way turning path. In either case, a new round of duplication cycle will resume at the starting point.

In the above embodiment, the jaws 11 and 12 are integrally formed of an elastic material. However, the present invention is not limited thereto, and the clips 11 and 12 may also contain a non-elastic material. For example, the jaws 11 and 12 are only externally composed of a flexible mold material, and the inside includes a linkage composed of rigid members such as a rod and a pivot joint. Linkage). In this case, the connectors 40a and 40b can still be used to relatively secure the jaws 11 and 12 with the four-bar linkage 20 and the chassis 30 by being coupled to the pivot or link. Obviously, the four-bar linkage mechanism and other types of transmission mechanisms can still drive the jaws in the closed state to simulate the human hand squeezing the dumpling filling sac in the closed state.

If a non-elastic material is used, the jaws 11 and 12 themselves may lack sufficient elasticity, so after completing the action of clamping the dumpling filling capsule, it may not be possible to return from the compressed position to the original position by its own elasticity. To this end, the technical solution of arranging the elastic member 14 in the four-bar linkage 20 as described above can be employed, so that the jaws 11 and 12 can be forced to return to the original position after each action of clamping the filling capsule is completed. .

Alternatively, the current squeeze rail 4 can be further modified to include two sub-rails 4a and 4b: the first strip guide rail 4a has a lower edge of the rail that gradually tapers or descends along the direction of travel of the forming unit 100, Functionally for driving the pair of jaws 11 and 12 to simulate the action of injecting the dumpling filling bag inwardly along the plane in which the pair of jaws 11 and 12 are in a closed state, thereby being defined as an extruded sub-guide; the second strip The guide rail 4b is disposed downstream of the extrusion sub-guide 4a in the traveling direction of the forming unit 100, and has an upper edge of the rail which gradually protrudes or rises in the traveling direction of the forming unit 100, and is functionally used for driving the roller 23 and the four-way backward. The lever mechanism 20 thereby forces the pair of jaws 11 and 12 to be reset, thus being defined as a reset sub-rail. In this way, as long as the roller 23 is designed to pass through the extrusion sub-guide 4a and the reset sub-guide 4b in the traveling direction of the forming unit 100, the pair of clamps can be driven along the plane in which they are located in the initial position. The reciprocating action between the compression positions does not have to rely on the elastic material and the elasticity of the elastic member to be reset.

It can be seen that even in the case where the mold and its pressing device are completely non-elastic, it is possible to drive the crucible along the plane in which it is located by using a bidirectional pressing device composed of a transmission mechanism and a bidirectional pressing guide rail. Retraction or expansion, in order to simulate the two hand movements of the filling capsule and then release the extrusion, thereby ensuring that the object of the invention can be fully realized. Of course, as a further alternative, the two-way extrusion device can also be constructed from a fluid pressure device comprising the cavity (see description above) and will not be repeated here.

Of course, in the case where the clips 11 and 12 are entirely composed of an elastic material, the above-described bi-directional pressing device is still applicable, and will not be described herein.
