The lower mold unit includes two lower molds respectively arranged in the first working area and the second working area and capable of moving along the axial direction.

The upper die unit is spaced apart from the lower die unit along the axial direction, and includes an upper hot-press central die and an upper hot-press transfer die. The upper die unit moves between a first reversing position and a second reversing position along a moving direction, and at the first reversing position At this time, the upper hot-pressing central mold is located in the dredging area, and can be matched with the dredging mold, and is suitable for molding the embryo unit, and is suitable for obtaining the embryo unit by the dredging mould. The lower mold is matched, and is suitable for hot-pressing the embryo unit, and is suitable for releasing the embryo unit to the corresponding lower mold. The upper hot-pressing transfer mold is located in the second working area, and can be matched with the corresponding lower mold, and is suitable for hot-pressing the embryo unit, and is suitable for releasing the embryo unit in the corresponding lower mold.

Other features and functions of the present invention will be clearly presented in the embodiments with reference to the drawings, wherein: Fig. 1 is a front view illustrating a forming machine disclosed in the patent application No. 201328860 of the Republic of China; Fig. 2 is a front view illustrating an embodiment of the forming machine of the new slurry product; Fig. 3 is a side view of this embodiment; Fig. 4 is a perspective view of a part of this embodiment; Fig. 5 is a front view similar to Fig. 2, but a slurry scooping mold and two lower molds move along an axis direction to be matched in an upper hot-pressing central mold and an upper hot-pressing transfer mold; Fig. 6 is a front view similar to Fig. The positions of the lower molds are different from Table 1.

Referring to Fig. 2, Fig. 3 and Fig. 4, an embodiment of the molding machine of the new slurry product includes a frame unit 2, a pulp extraction unit 3, a lower mold unit 4, an upper mold unit 5, and a driving unit 6.

The frame unit 2 defines a pulp extraction area 21 , a first working area 22 located on one side of the pulp extraction area 21 , and a second working area 23 . The second working area 23 is located on a side of the first working area 22 away from the pulp extraction area 21 . In this embodiment, the pulp extraction area 21 , the first working area 22 and the second working area 23 are arranged along a moving direction X.

The rack unit 2 includes three guide column sets 24 and two sliding rails 25 . The guide column sets 24 are installed in the slurry fishing area 21 , the first working area 22 and the second working area 23 . Each guide post set 24 has four guide posts 241 extending along an axis L and spaced apart from each other. The sliding rails 25 extend along the moving direction X and cross over the pulp extraction area 21 , the first working area 22 and the second working area 23 . In this embodiment, the moving direction X is substantially perpendicular to the axis L.

The pulp extraction unit 3 is arranged in the pulp extraction area 21 and includes a pulp bucket 31 suitable for containing pulp, and a pulp extraction mold 32 that can move relative to the pulp bucket 31 along the axis L. The slurry scooping mold 32 is slid on the guide columns 241 of the corresponding guide column set 24, and can move along the axis L direction, and is suitable for scooping slurry to form an embryo unit I, II, III (as shown in Table 1).

It is worth noting that, since the technique of scooping out the slurry in the slurry tank 31 through the slurry pulling mold 32 and dehydrating and shaping the slurry is not a technical feature of this case, and those skilled in the art can deduce the expanded details based on the above description, so no further explanation is given.

The lower mold unit 4 includes two lower molds 41 respectively disposed on the first working area 22 and the second working area 23 . Each of the lower molds 41 is slidingly engaged with the guide posts 241 of the corresponding guide post set 24 , and can move along the axis L direction.

The upper mold unit 5 is spaced apart from the lower mold unit 4 along the axis L, and includes an upper hot-press central mold 51 and an upper hot-press transfer mold 52 . In this embodiment, the upper hot-press transfer mold 52 and the upper hot-press central mold 51 are arranged along the moving direction X, and are connected to the upper hot-press central mold 51 , and together with the upper hot-press central mold 51 to move.

In this embodiment, each of the lower mold 41, the upper hot-press central mold 51, and the upper hot-press transfer mold 52 can acquire the embryonic units I, II, and III (as shown in Table 1) or release the embryonic units I, II, and III (as shown in Table 1) through positive-pressure airflow or negative-pressure airflow, and generate heat energy through the internal heating structure. Since it is not a technical feature of the present case, and those skilled in the art can infer the expanded details based on the above description, no further description is given.

The upper mold unit 5 slides on the slide rails 25, and can move between a first reversing position (as shown in FIG. 2 ) and a second reversing position (as shown in FIG. 6 ) along the moving direction X. At each reversing position, the upper hot-pressing central mold 51 is located in the pulp extraction area 21, and the upper hot-pressing transfer mold 52 is located in the second working area 23. In the second reversing position, the upper hot-press central mold 51 is located in the first working area 22 , and the upper hot-press transfer mold 52 is located in the second working area 23 .

The driving unit 6 includes three lower driving groups 61 and an upper driving group 62 .

The lower driving groups 61 are installed in the pulp extraction area 21 , the first working area 22 and the second working area 23 of the rack unit 2 . Each of the lower driving groups 61 can be a hydraulic cylinder or a pneumatic cylinder, and has a rod 611 that expands and contracts along the axis L, and is used to drive the slurry extraction mold 32 and the lower molds 41 to move along the axis L.

Thereby, the slurry extraction mold 32 or each of the lower molds 41 can move along the axis L between an engaged position and a disengaged position. The pair of rake molds 32 are located When it is in the combined position, the slurry pulling mold 32 is matched with the upper hot-pressing central mold 51 in the first reversing position. When the slurry extraction mold 32 is located at the disengagement position, the slurry extraction mold 32 is away from the upper mold unit 5 .

When the lower mold 41 located in the first working area 22 is at the abutment position, it abuts with the upper hot-pressing transfer mold 52 at the first reversing position, or with the upper hot-pressing central mold 51 at the second reversing position. When the lower mold 41 located in the second working area 23 is located in the abutment position, the upper heat press transfer mold 52 in the second reversing position is abutted. When each of the lower molds 41 is located at the disengagement position, it is away from the upper mold unit 5 .

The upper driving group 62 is mounted on the frame unit 2 for driving the upper mold unit 5 to move along the moving direction X. In this embodiment, the upper driving group 62 has a screw rod 621 extending along the moving direction X and rotatably mounted on the frame unit 2 , and a motor 622 driving the screw rod 621 to rotate. The screw 621 is screwed to the upper mold unit 5 .

It should be noted that the upper driving group 62 is not limited to the combination of the screw 621 and the motor 622 , and may also be a hydraulic cylinder or a pneumatic cylinder in other variations of this embodiment.

In this way, when the rod 611 of each lower driving group 61 stretches, it will drive the corresponding dredging mold 32 or the corresponding lower mold 41 to rise or fall along the axis L direction. When the screw motor 622 drives the screw 621 to rotate, it will drive the upper mold unit 5 to move leftward or rightward along the moving direction X. Because those skilled in the art can deduce the expanded details according to the above description, therefore, the lower drive group 61 and the upper drive group 61 will be omitted below. The operation of the drive group 62 is explained.

To distinguish the movement sequence of the upper mold unit 5, the process of the pulp product is as follows:

step 1:

Referring to Fig. 2, Fig. 5 and Table 1, when the upper mold unit 5 is located at the first reversing position as shown in Fig. 2, the upper hot-press central mold 51 is located in the slurry extraction area 21, and the upper hot-press transfer mold 52 is located in the first working area 22.

After the slurry scooping mold 32 scoops the slurry to form the first embryo unit 1, it moves upwards to match the upper hot-pressing central mold 51 at the first reversing position. At this time, the upper hot-pressing central mold 51 will draw the first embryo unit I out of the slurry extraction mold 32 through the negative-pressure airflow, and the slurry extraction mold 32 will move downwards away from the upper mold unit 5, and immerse in the pulp barrel 31, so that the first embryo unit I is left in the upper hot-press central mold 51.

Step 2:

6, 7 and Table 1, when the upper mold unit 5 moves from the first reversing position in FIG. 2 to the second reversing position in FIG.

The lower mold 41 of the first working area 22 moves upwards to match the upper hot-pressing central mold 51, and as shown in the light gray block in Table 1, the first embryo unit I is hot-pressed for the first time. Then, the lower mold 41 of the first working area 22 moves downwards away from the upper mold unit 5 . At this time, the upper hot-pressing central mold 51 will push the first embryo unit I through the air flow of positive pressure, so that the first embryo unit I is separated from the upper hot-pressing central mold 51, and the lower mold 41 of the first working area 22 will absorb the first embryo unit I through the airflow of negative pressure, so that the first embryo unit I is located in the lower mold 41 of the first working area 22.

Step 3:

Referring to Fig. 2, Fig. 5 and Table 1, when the upper mold unit 5 is moved from the second reversing position in Fig. 6 to the first reversing position as shown in Fig. 2, the upper hot-press central mold 51 is located in the slurry extraction area 21, and the upper hot-press transfer mold 52 is located in the first working area 22.

The lower mold 41 of the first working area 22 moves upwards to match the upper hot-pressing transfer mold 52, and as shown in the light gray block in Table 1, the first embryo unit I is hot-pressed for the second time. Then, the lower mold 41 of the first working area 22 moves downwards away from the upper mold unit 5 . At this time, the lower mold 41 of the first working area 22 will push the first embryo unit I through the positive air flow, so that the first embryo unit I is separated from the lower mold of the first working area 22 41, and the upper hot-press transfer mold 52 will suck the first embryo unit I through negative-pressure airflow, so that the first embryo unit I is located on the upper hot-press transfer mold 52.

After the slurry scooping mold 32 scoops the slurry to form the second embryonic unit II, it moves upwards to match the upper hot-pressing central mold 51 . At this time, the upper hot-pressing central mold 51 will draw the second embryonic unit II out of the slurry scooping mold 32 through the airflow of negative pressure, and the slurry scooping mold 32 will move down to be far away from the upper mold unit 5, and immerse in the slurry tank 31, so that the third embryonic unit II remains in the upper hot-pressing central mold 51.

Step 4:

Referring to Fig. 6, Fig. 7 and Table 1, when the upper mold unit 5 moves from the first reversing position in Fig. 2 to the second reversing position in Fig. 6 again, the upper hot pressing central mold 51 is located in the first working area 22, and the upper hot pressing transfer mold 52 is located in the second working area 23.

The lower mold 41 of the second working area 23 moves upward to match the upper hot-press transfer mold 52, and as shown in the light gray block in Table 1, hot-press the first embryo unit I for the third time. Then, the upper hot-press transfer mold 52 will push the first embryo unit I through the air flow of positive pressure, so that the first embryo unit I will break away from the upper hot-press transfer mold 52, and the lower mold 41 of the second working area 23 will absorb the first embryo unit I through the air flow of negative pressure, so that the first embryo unit I is positioned at the lower mold 41 of the second working area 23, and demoulding is completed.

It is worth noting that, after the demoulding of the embryo unit 1 is completed, the embryo unit can be transported manually, or by a mechanical arm, or a suction cup holder, or other equipment to carry out trimming, defect detection, bagging and other processes in sequence.

The lower mold 41 of the first working area 22 moves upwards to match the upper hot-pressing central mold 51, and as shown in the dark gray block in Table 1, the second embryonic unit II is hot-pressed for the first time. Then, the lower mold 41 of the first working area 22 moves downwards away from the upper mold unit 5 . At this time, the upper hot-pressing central mold 51 will push the second embryonic unit II through the airflow of positive pressure, so that the second embryonic unit II is separated from the upper hot-pressing central mold 51, and the lower mold 41 of the first working area 22 will absorb the second embryonic unit II through the airflow of negative pressure, so that the second embryonic unit II is located in the lower mold 41 of the first working area 22.

Step 5:

Referring to Fig. 2, Fig. 5 and Table 1, when the upper mold unit 5 is moved from the reversing position in Fig. 6 to the reversing position in Fig. 2 again, the upper hot-pressing central mold 51 is located in the slurry extraction area 21, and the upper hot-pressing transfer mold 52 is located in the first working area 22.

The lower mold 41 of the first working area 22 moves upward to match the upper hot-pressing transfer mold 52, and as shown in the dark gray block in Table 1, the second embryonic unit II is hot-pressed for the second time. Then, the lower mold 41 of the first working area 22 moves downwards away from the upper mold unit 5 . At this time, the lower mold 41 of the first working area 22 will push the second embryonic unit II through the airflow of positive pressure, so that the second embryonic unit II is separated from the lower mold 41 of the first working area 22, and the upper hot-pressing transfer mold 52 will absorb the second embryonic unit II through the airflow of negative pressure, so that the second embryonic unit II is located in the upper hot-pressing transfer mold 52.

After the slurry scooping mold 32 scoops the slurry to form the third embryonic unit III, it moves upwards to match the upper hot-pressing central mold 51 . At this moment, the upper hot-pressing central mold 51 The third embryo unit III will be sucked out of the slurry extraction mold 32 by the negative pressure airflow, and the slurry extraction mold 32 will move down to be away from the upper mold unit 5, and be immersed in the pulp barrel 31, so that the third embryo unit III is left in the upper hot-pressing central mold 51.

Repeating this cycle, each embryonic unit can sequentially complete the first hot pressing, second hot pressing, third hot pressing and demoulding procedures.

It is worth noting that the times and positions of hot pressing can be determined only by changing the mating time of the upper hot-press transfer mold 52 and the corresponding lower mold 41, or changing the mating time of the upper hot-press central mold 51 and the corresponding lower mold 41. For example: control the mating time of the upper hot-press transfer mold 52 and the lower mold 41 of the first working area 22 within 6 seconds. At this time, the upper hot-press transfer mold 52 is a simple transfer function, and the purpose is to transfer the corresponding embryo unit from the lower mold 41 of the first working area 22 to the upper hot-press transfer mold 52. In this way, the process can be controlled to only perform hot pressing in step 2 and step 4, and there are only two hot pressing procedures.

For example: control the mating time of the upper hot pressing transfer mold 52 and the lower mold 41 of the first working area 22 at about 50 seconds, the process can be controlled to carry out hot pressing in step 2, step 3, and step 4, and there are 3 hot pressing procedures. Of course, it is also possible to control the mating time between the upper hot-press transfer mold 52 and the lower mold 41 of the second working area 23 within about 50 seconds or within 6 seconds, so as to determine whether the upper hot-press transfer mold 52 is performing a hot-pressing procedure in the second working area 23, or only for a simple demoulding function.

In addition, the lower dies 41 and the slurry removal die 32 can meet actual needs It is required to move up and down together, or move up and down separately, but it does not affect the first hot pressing, second hot pressing, third hot pressing and demoulding procedures. Since those with ordinary knowledge in the field can infer the expansion details based on the above description, no more explanation is given.

Through the above description, the advantages of the foregoing embodiments can be summarized as follows: the new model can make each embryo unit undergo the first hot pressing, the second hot pressing, the third hot pressing, and the demoulding procedures in sequence, and the most important thing is that the upper mold unit 5 only needs to be reversed once left and right to stay in two positions, and different procedures such as forming, hot pressing, and demoulding can be performed on up to three embryo units at the same time. In this way, not only can the process time be greatly shortened, but also the upper mold unit 5 only needs to use one power source (motor 622) and one screw 621 to achieve the purpose of synchronous movement, thereby simplifying the structure and reducing the equipment cost.

But the above-mentioned ones are only embodiments of the present model, and should not limit the scope of the present model implementation. All simple equivalent changes and modifications made according to the scope of the patent application for the present model and the contents of the patent specification are still within the scope covered by the patent of the present model.
