Description

The invention relates to a hybrid forming machine, in particular such a machine that can machine more than two independent workpieces in the horizontal direction.

Molded manufacturing is one of the technologies widely used in industry today. In the case of thermoplastic materials such as expandable polystyrene (EPS), expandable polyethylene copolymer (EPO), expandable polypropylene (EPP) and expandable polyethylene (EPE), the male and female molds of a mold usually press together in alignment with one another, see above that the raw material enters the mold and then is formed by steam heating. The shape is then cooled and demolded due to the vacuum. This allows mass production to be done quickly.

Without a large operating area at a factory, a limited number of the production machines can be used. In addition, a manufacturing machine is equipped with only one mold base, which can manufacture only one workpiece at a time while still requiring the supervision of an operator. Production capability is therefore severely limited.

In view of the shortcomings of the conventional embodiment, an object of the invention is to provide a hybrid forming machine which can machine more than two independent workpieces in the horizontal direction to reduce the overall cost of a manufacturing machine and improve production efficiency.

To solve the task, the hybrid forming machine consists of a frame, a first mold base, a second mold base, a third mold base, a mold set and a drive mechanism. The first mold base is mounted on the frame. The second mold base is coupled to the first mold base and can move horizontally against the first mold base. The third mold base is arranged between the first mold base and the second mold base and can move in the horizontal direction against the first mold base. The mold set consists of a first mold and a second mold, the first mold having a first male and a first female, which are fixed to the two opposite surfaces of the third mold base and the first mold base, while the second mold has a second male and a second die fixed to the two opposite surfaces of the third mold base and the second mold base. The engine comprises at least one first drive member and at least one second drive member, wherein the first drive member is suitably coupled to a surface of the third mold base opposite the first mold base for operating the third mold base, while the second drive member is suitably coupled to a surface of the third mold base for operating the second mold base the third mold base opposite surface of the second mold base is coupled.

In a preferred embodiment, the engine further comprises a first coupling part and a second coupling part, the first drive member being fixed to the third mold base via the first coupling part and the second coupling part.

In a preferred embodiment, the hybrid forming machine further comprises a control unit electrically connected to the engine for controlling the stroke distance and speed of the second mold base and the third mold base.

In a preferred embodiment, the engine further comprises at least one first drive unit and at least one second drive unit, wherein the first drive unit can operate the third mold base in a horizontal direction against the first mold base via the first drive member, while the second drive unit can operate the second mold base via the second drive member in the horizontal direction against the first mold base.

In a preferred embodiment, the first drive member is attached to at least one side of the third mold base and the second drive member is attached to at least one side or center of the second mold base.

In a preferred embodiment, the hybrid forming machine further comprises a slideway unit having a plurality of slides, wherein the second mold base and the third mold base are slidably mounted on the frame via these slides.

In a preferred embodiment, the frame is designed with an outlet above which the node point of the first male part with the first female part and the node point of the second male part with the second female part are located.

In such an openable hybrid forming machine, the third mold base approach the first mold base in the horizontal direction so that the first mold processes a workpiece. At the same time, the second mold base can approach the third mold base in the horizontal direction, so that the second mold works on a different workpiece. The mold opening, the mold closing and the machining of the two molds are performed independently of each other, therefore the entire cost of a manufacturing machine can be reduced and the production efficiency can be improved.

Further goals, advantages, features and application possibilities of the present invention result from the following description of the exemplary embodiments with reference to the drawings. It should be noted that the directions mentioned in the exemplary embodiments such as “top, bottom, left, right, front, back” only refer to the directions shown in the given figures. In this regard, the directions set forth are for description only and are not intended to limit the embodiment of the present invention. In the exemplary embodiments below, the same or similar symbols refer to the same or similar components.

How out 1 as a side view of an embodiment according to the invention, the hybrid forming machine 1 according to the invention, suitable for more than two workpieces for simultaneous or separate processing, consists of a frame 100, a first mold base 200, a second mold base 300, a third mold base 400 and a mold set 600. Here, the first mold base 200 is mounted on the frame 100. The second mold base 300 is coupled to the first mold base 200 and can move in the horizontal direction H against the first mold base 200 . The third mold base 400 is arranged between the first mold base 200 and the second mold base 300 and can move in the horizontal direction H against the first mold base 200 . The mold set 600 consists of a first mold 610 and a second mold 620, wherein the first mold 610 is arranged between the first mold base 200 and the third mold base 400 and the second mold 620 is arranged between the second mold base 300 and the third mold base 400.

The first mold base 200 further has a first die mounting surface 210 , while the second mold base 300 includes a second die mounting surface 310 and a back 320 , and the third mold base 400 includes a first male mounting surface 410 and a second male mounting surface 420 . The first die mounting surface 210 is opposite the first male mounting surface 410 while the second die mounting surface 310 is opposite the second male mounting surface 420 . Furthermore, the first forming tool 610 has a first die 612 and a first male die 614 , the first die 612 being mounted on the first die mounting surface 210 and the first male 614 being mounted on the first male mounting surface 410 . On the other hand, the second forming die 620 has a second female 622 and a second male 624 , the second female 622 being mounted on the second female mounting surface 310 and the second male 624 being mounted on the second male mounting surface 420 . That is, the first female 612 and the first male 614 are fixed to the two opposite surfaces of the first mold base 200 and the third mold base 400, while the second female 622 and the second male 624 are fixed to the two opposite surfaces of the second mold base 300 and of the third mold base 400 are fixed.

The hybrid forming machine 1 also includes a drive unit 700, which is provided with at least one first drive unit 710 with a first drive member 712, the first drive member 712 being coupled to a surface of the third mold base 400 lying opposite the first mold base 200, i.e. coupled to the first male mold mounting surface 410 for operating the third mold base 400. In the present embodiment, the first drive unit 710 may be a hydraulic cylinder, for example, and the first drive link 712 may be a hydraulic linkage, for example. Depending on the workpiece processing needs of the first die 610, either the first drive unit 710 can be replaced with a pneumatic cylinder or an electric cylinder, or the first drive member 712 can be replaced with a screw, shaft or connecting rod.

The engine 700 further comprises a first coupling part 730 and a second coupling part 740. Like the second coupling part 740, the first coupling part 730 is formed as a thick metal plate, for example. The first coupling part 730 and the second coupling part 740 are mounted on the first male mounting surface 410 and the second male mounting surface 420, respectively. The first driving member 712 is fixed to the third mold base 400 via the first coupling part 730 and the second coupling part 740 . Thus, the first drive unit 710 can move the third mold base 400 in the horizontal direction H against the first mold base 200 via the first drive member 712 to selectively compress or separate the first female die 612 and the first male die 614 for workpiece processing.

The engine 700 is also provided with at least one second drive unit 720 with a second drive member 722, the second drive member 722 being coupled to a surface of the second mold base 300 which faces away from the third mold base 400, i.e. to the rear side 320. In the present embodiment, the second drive unit 720 can consist of a hydraulic cylinder, for example, and the second drive member 722 can be designed as a hydraulic linkage, for example. Depending on the workpiece processing needs of the second forming tool 620, the second drive unit 720 and the second drive member 722 can be replaced with equivalent drive devices and components as in the case of the first drive unit 710. Thus, the second drive unit 720 can move the second mold base 300 in the horizontal direction H against the first mold base 200 via the second drive member 722 to selectively compress or separate the second die 622 and the second male die 624 for workpiece processing.

The engine 700 preferably also comprises a plurality of guide pieces 750, which are designed, for example, as a guide column and are connected to the first mold base 200, that is to say extend in the horizontal direction H. In addition, the second mold base 300 and the third mold base 400 are fitted on the guide pieces 750 . Thereby, the directions for moving the second mold base 300 and the third mold base 400 are limited. The hybrid forming machine 1 also includes a trestle 500 which is mounted on the frame 100 or opposite the first mold base 200 . In the present embodiment, for example, two first driving units 710 and two first driving members 712 are provided, which are attached to both sides of the first mold base 200 and to both sides of the third mold base 400, respectively. In addition, for example, a second drive unit 720 and a second drive member 722 are provided, which are inserted through the trestle 500 or fixed to the center of the second mold base 300 . In addition, for example, four guide pieces 750 are provided, which are inserted through the first mold base 200, the second mold base 300, the third mold base 400 and four corners of the trestle 500. With such a configuration, the individual mold bases can press against each other except for the mold closure, so that the components can operate the third mold base 400 and the second mold base 300 along the guide pieces 750 against the first mold base 200 to move without mutual interference. In another embodiment, the second mold base 300 and the third mold base 400 may be slidably attached to the guide pieces 750 in conjunction with carriages. In addition, the second drive unit 720 can be increased in number or attached to a side of the second mold base 300 in terms of practical number depending on the processing pressure.

In addition, the hybrid forming machine 1 can also include a slide guide unit with a plurality of slides 800, with the individual slides 800 serving, for example, to accommodate the second mold base 300 and the third mold base 400, while the second mold base 300 and the third mold base 400 via the slides 800 are slidably attached to the frame 100. Thereby, the second mold base 300 and the third mold base 400 are supported and can slip against the first mold base 200 . In another embodiment, the second mold base 300 and the third mold base 400 can be purely slidably attached to the guide pieces 750, yielding the same effect.

The hybrid forming machine 1 preferably also includes a control unit (not shown), which is an industrial PC, for example, and is electrically connected to the drive mechanism 700 in order to control the lifting distance and the lifting speed of the second mold base 300 and the third mold base 400 by means of a To control control unit pre-stored control program.

The following describes how the hybrid forming machine 1 according to the invention interacts with various components for simultaneous processing. For that will open 2 as a side view of the opening second mold of the hybrid forming machine according to the invention in relation to FIG 1 and 3 as a side view of the opening first mold of the hybrid forming machine according to the invention in relation to FIG 1 referred. When the third mold base 400 is pulled by the first drive member 712 of the first drive unit 710 so that the first male mold 614 positively presses against the first female mold 612, and the second mold base 300 is displaced by the second drive member 722 of the second drive unit 720 so that the second male mold 624 positively presses against the second female mold 622 (see 1 ), raw material for the workpiece can be filled in the first die 610 and the second die 620, and then properly formed by steam heating. In the present embodiment, the first mold 610 is suitable for processing the low-density plastic workpiece, such as expanded polystyrene workpiece, because the third mold base 400 includes the first driving member 712, both of which coupling surfaces are relatively smaller and on both sides of the third mold base 400 are arranged, takes up the drive. On the other hand, the second mold base 300 takes the second driving member 722, whose both coupling surfaces are relatively larger and are located at the center of the second mold base 300, for driving and can bear relatively larger load, the second mold 620 is suitable for processing the plastic workpiece with higher density, such as expanded polypropylene workpiece. In a further embodiment, the first forming tool 610, like the second forming tool 620, can process workpieces made of the same material or of different materials at the same time, as long as the pressure and temperature required for forming the workpiece can be maintained.

Once the workpiece is formed in the second mold 620, the control unit will cause the second drive unit 720 and the second drive link 722 to operate the second mold base 300 to move away from the third mold base 400 (see FIG 2 ) so that the second male mold 624 separates from the second female mold 622. The frame 100 is preferably formed with an outlet 110 which is arranged, for example, as a hollow structure in the center of the frame 100 . Above the outlet 110 is the junction of the second male mold 624 with the second female mold 622. With such a design, the second mold 620 can open separately, even if the workpiece has not yet been formed in the first mold 610. After a mold is opened, the finished part will fall out of the second male mold 624 directly into the outlet 110 . This eliminates the need for additional transportation or relocation of the finished part from the process.

Once the workpiece is formed in the first mold 610, the control unit will cause the first drive unit 710 and the first drive link 712 to operate the third mold base 400 to move away from the first mold base 200 (see FIG 3 ) so that the first male mold 614 separates from the first female mold 612. The junction of the first male mold 614 with the first female mold 612 is also preferably located above the outlet 110. After mold opening, the finished part will fall out of the first female mold 612 directly into the outlet 110. This also eliminates the need for additional transport or relocation of the finished part from the process.

While the first mold 610 is processing a workpiece, the second mold 620 can process another workpiece simultaneously. Therefore, compared with the traditional machining and forming machines, the production efficiency can be increased twice, the productivity can be greatly improved, and the overall cost of the manufacturing machine can be reduced. In addition, the engine is designed in the horizontal direction H, so the engine does not have to withstand repeated stroke of a huge mold base in the vertical direction. This reduces the overall cost of the manufacturing machine due to a simpler mechanical design.

Furthermore, the first drive unit 710 and the second drive unit 720 remain independent of each other, which is why the hybrid forming machine 1 according to the invention can now carry out the separate production with the first mold 610 or the second mold 620 compared to the conventional overlapping mold set, with no more sequential mold opening is required. For example, when processing only the first mold 610, the first drive unit 710 can operate the third mold base 400 and the second mold base 300 to move away from the first mold base 200, so that the first mold 610 opens and the manufactured workpiece can be removed therefrom, i.e. independently from the second mold 620. When processing only by the second mold 620, the second driving unit 720 can operate the second mold base 300 to move away from the third mold base 400, so that the second mold 620 opens and the manufactured workpiece can be removed therefrom. In addition, although the hybrid forming machine 1 is similar to the length of the frame of a conventional manufacturing machine, it can be equipped with more than two forming dies, so that the production efficiency can be increased more than twice and various workpieces can be processed at the same time. This significantly improves operational flexibility, production efficiency and economic benefits.

The invention is not limited to the exemplary embodiments, but is variable in many ways within the scope of the disclosure. In this context all new individual and combination features disclosed in the description and/or drawing are regarded as essential to the invention.
