The description is as follows:

referring to fig. 1, fig. 1 is a schematic side view of a hybrid mold-opening molding machine according to an embodiment of the present invention. The hybrid mold-opening molding machine 1 of the present embodiment is suitable for processing more than two workpieces simultaneously or individually, and includes a base 100, a first mold holder 200, a second mold holder 300, a third mold holder 400 and a mold set 600, wherein the first mold holder 200 is disposed on the base 100; the second die holder 300 is connected to the first die holder 200 and is adapted to move in a horizontal direction H relative to the first die holder 200; the third die holder 400 is disposed between the first die holder 200 and the second die holder 300 and adapted to move relative to the first die holder 200 along the horizontal direction H; the mold set 600 includes a first mold 610 and a second mold 620, wherein the first mold 610 is disposed between the first mold holder 200 and the third mold holder 400, and the second mold 620 is disposed between the second mold holder 300 and the third mold holder 400.

In detail, the first mold base 200 includes a first female mold surface 210, the second mold base 300 includes a second female mold surface 310 and a back surface 320, and the third mold base 400 includes a first male mold surface 410 and a second male mold surface 420, wherein the first female mold surface 210 and the first male mold surface 410 are opposite to each other, and the second female mold surface 310 and the second male mold surface 420 are opposite to each other. In addition, the first mold 610 includes a first female mold 612 and a first male mold 614, wherein the first female mold 612 is disposed on the first female mold surface 210, and the first male mold 614 is disposed on the first male mold surface 410; on the other hand, the second mold 620 includes a second female mold 622 and a second male mold 624, wherein the second female mold 622 is disposed on the second female mold surface 310, and the second male mold 624 is disposed on the second male mold surface 420. In other words, the first female die 612 and the first male die 614 are respectively disposed on two opposite surfaces of the first mold base 610 and the third mold base 400, and the second female die 622 and the second male die 624 are respectively disposed on two opposite surfaces of the second mold base 300 and the third mold base 400.

Specifically, the hybrid mold-opening molding machine 1 further includes a driving mechanism 700, the driving mechanism 700 includes at least one first driving device 710, the first driving device 710 includes a first driving member 712, and the first driving member 712 is connected to a surface of the third mold holder 400 opposite to the first mold holder 200, i.e. the first male mold surface 410, for driving the third mold holder 400. In the present embodiment, the first driving device 710 is, for example, a hydraulic cylinder, and the first driving element 712 is, for example, a hydraulic rod, but the first driving device 710 may be replaced by a pneumatic cylinder, an electric cylinder, or other driving devices, or the first driving element 712 may be replaced by a screw, a shaft, a crank rod, or other components, according to the actual requirement of the first mold 610 for processing the workpiece.

More specifically, the driving mechanism 700 further includes a first connecting member 730 and a second connecting member 740, wherein the first connecting member 730 and the second connecting member 740 are thick metal plates, the first connecting member 730 is disposed on the first male mold surface 410, the second connecting member 740 is disposed on the second male mold surface 420, and the first driving member 712 is fixed to the third mold base 400 through the first connecting member 730 and the second connecting member 740. Thus, the first driving device 710 can drive the third die holder 400 to move relative to the first die holder 200 along the horizontal direction H by the first driving unit 712, so that the first female die 612 and the first male die 614 selectively open or close the dies and process the workpiece.

On the other hand, the driving mechanism 700 further includes at least one second driving device 720, the second driving device 720 includes a second driving member 722, and the second driving member 722 is connected to the surface of the second die holder 300 away from the third die holder 400, i.e. the back surface 320. In the embodiment, the second driving device 720 is, for example, a hydraulic cylinder, and the second driving member 722 is, for example, a hydraulic rod, but similar to the first driving device 710, the second driving device 720 and the second driving member 722 can be replaced by other driving devices and corresponding components according to the actual requirement of the second mold 620 for processing the workpiece. Thus, the second driving device 720 can drive the second mold holder 300 to move relative to the first mold holder 200 along the horizontal direction H by the second driving member 722, so that the second female mold 622 and the second male mold 624 selectively open or close the molds to process the workpiece.

Preferably, the driving mechanism 700 further includes a plurality of guides 750, such as guide posts, connected to the first die holder 200 and extending along the horizontal direction H, and the second die holder 300 and the third die holder 400 are sleeved on the guides 750, so as to limit the moving direction of the second die holder 300 and the third die holder 400. More specifically, the hybrid mold-opening molding machine 1 further includes a supporting base 500, and the supporting base 500 is disposed on the base 100 and opposite to the first mold base 200. In the present embodiment, the number of the first driving devices 710 and the first driving members 712 is, for example, two, and the first driving devices are respectively located at two sides of the first mold base 200 and disposed at two sides of the third mold base 400; the number of the second driving devices 720 and the second driving members 722 is, for example, one, and the second driving devices are disposed through the supporting base 500 and on the central portion of the second mold base 300; the number of the guides 750 is, for example, four, and the guides are respectively inserted into four corners of the first mold base 200, the second mold base 300, the third mold base 400, and the support base 500. With this arrangement, the respective units can drive the third die holder 400 and the second die holder 300 to move relative to the first die holder 200 along the guide 750 without interfering with each other, except that the die holders abut against each other when clamping the dies. However, in other possible embodiments, the second mold holder 300 and the third mold holder 400 can be slidably disposed on the guide 750 by a slide, and the second driving device 720 can be also disposed on the side of the second mold holder 300 according to the actual requirement of the machining pressure, and the like, which is not limited by the present invention.

In addition, the hybrid type mold-opening molding machine 1 further includes a sliding mechanism, the sliding mechanism includes a plurality of sliding members 800, wherein the sliding members 800 are, for example, sliding blocks for supporting the weight of the second mold holder 300 and the third mold holder 400, and the second mold holder 300 and the third mold holder 400 are slidably disposed on the base 100 through the sliding members 800. Thereby, the second die holder 300 and the third die holder 400 can slide relative to the first die holder 200 in a bottom-supported state. However, in other possible embodiments, the second mold unit 300 and the third mold unit 400 can be simply slidably disposed on the guide 750, and the same effect can be achieved.

Preferably, the hybrid mold-opening molding machine 1 further comprises a control unit (not shown), wherein the control unit is, for example, an industrial computer and is electrically connected to the driving mechanism 700, and the control unit controls the moving stroke and/or the moving speed of the second mold holder 300 and the third mold holder 400 through a control program pre-programmed in the control unit.

Referring to fig. 2 and fig. 3, please refer to fig. 2 and fig. 3 together, in which fig. 2 is a schematic side view of the hybrid open-mold molding machine of fig. 1 when the second mold is open, and fig. 3 is a schematic side view of the hybrid open-mold molding machine of fig. 1 when the first mold is open. When the third die holder 400 is pulled by the first driver 712 of the first driving means 710 so that the first male die 614 is closed with respect to the first female die 612, and the second die holder 300 is pushed by the second driver 722 of the second driving means 720 so that the second male die 624 is closed with respect to the second female die 622, thereby forming the state shown in fig. 1, the user can inject the raw material of the workpiece into the first die 610 and the second die 620, respectively, and shape the workpiece by means of, for example, steam heating. In the present embodiment, since the third mold base 400 uses the two first driving members 712 with smaller connecting area disposed on the two side portions as driving components, the first mold 610 is suitable for processing plastic workpieces with smaller density, such as styrofoam workpieces; on the other hand, since the second die holder 300 is driven by the second driving member 722 having a large connecting area disposed at the central portion thereof as a driving means, a large load is applied to the second die holder 300, and thus the second die 620 can process a plastic workpiece having a large density, for example, a foamed polypropylene workpiece. However, in other possible embodiments, the first mold 610 and the second mold 620 may process workpieces of the same material or different materials at the same time, as long as the pressure and temperature required for forming the workpieces can be satisfied.

After the workpiece in the second mold 620 is formed, the control unit can control the second driving device 720, and drive the second mold base 300 to move away from the third mold base 400 through the second driving device 722 as shown in fig. 2, so that the second female mold 622 is opened relative to the second male mold 624. Preferably, the base 100 is formed with the outlet 110, wherein the outlet 110 is, for example, a hollow structure and is located at a central portion of the base 100, and a boundary between the second male mold 624 and the second female mold 622 is located above the outlet 110. With such a configuration, even if the workpiece in the first mold 610 is not formed, the second mold 620 can be opened alone, and the finished product in the second male mold 624 after opening the mold can directly fall to the discharge port 110, thereby eliminating the need for additional handling or moving the finished product.

In addition, after the workpiece in the first mold 610 is formed, the control unit can control the first driving device 710 to drive the third mold holder 400 to move away from the first mold holder 200 through the first driving member 712 as shown in fig. 3, so that the first male mold 614 opens the mold relative to the first female mold 612. Preferably, the intersection of the first male mold 614 and the first female mold 612 is also located above the discharge port 110. Through such a configuration, the finished product located in the first female mold 612 after mold opening directly falls to the discharge port 110, and a process of additionally carrying or moving the finished product is omitted.

When the first mold 610 processes the internal workpiece, the second mold 620 can process the internal workpiece at the same time, so that the production efficiency can be increased to twice that of a general processing and forming machine, thereby greatly improving the production efficiency and reducing the total cost of the machine. On the other hand, since the driving mechanism is disposed in the horizontal direction H, there is no need to perform reverse movement in the vertical direction against the large weight of the die holder, so that the mechanism design is simple and the design and manufacturing costs are reduced.

In addition, since the first driving device 710 and the second driving device 720 are independent of each other, compared to the mold set with a general stacked design, the hybrid mold-opening molding machine 1 of the present embodiment can be separately processed by the first mold 610 or the second mold 620, and does not need to sequentially open the molds. For example, when a user only uses the first mold 610 to process, the first driving device 710 can push the third mold base 400 and the second mold base 300 away from the first mold base 200, so that the first mold 610 can open the mold and take out the processed workpiece therein without waiting for the processing operation of the second mold 620; when the user processes only the second mold 620, the second driving device 720 can move the second mold holder 300 away from the third mold holder 400, so that the second mold 620 opens the mold and takes out the processed workpiece inside. Moreover, because the length of the base of the hybrid mold-opening forming machine 1 is similar to that of a general machine, more than two sets of molds can be arranged, so that the production efficiency can be improved by more than two times, different types of workpieces can be processed, and the use flexibility, the production efficiency and the economic benefit are remarkably improved.

The present invention has been disclosed in the foregoing in terms of preferred embodiments, however, it should be understood by those skilled in the art that the embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of the invention. It should be noted that equivalent variations and permutations to the described embodiments are intended to be included within the scope of the invention. Therefore, the scope of the present invention is defined by the appended claims.
