Please refer to Figures 8 to 9, which are schematic cross-sectional views of the forming mold of the present invention forming a workpiece W into a formed part W'. Through the above-mentioned structure of the molding mold with detachable modules of the present invention, when a molded part W' (as shown in Figure 9) is to be manufactured, the action of the molding mold is detailed as follows.

First, as shown in Figure 8, a workpiece W (for example, a flat plate, but not limited to this) is provided, and the workpiece W is pressed against the upper mold 1, the upper pressing member 2, and the lower between the mold 3 and the lower pressing part 4; at this time, the positional relationship between the upper mold 1, the upper pressing part 2, the lower mold 3 and the lower pressing part 4 forms a first configuration.

Then, as shown in Figure 9, relative to the first configuration, a relative movement occurs between the upper mold 1 and the upper pressing part 2, and a relative movement also occurs between the lower mold 3 and the lower pressing part 4. Movement causes the positional relationship between the upper mold 1, the upper pressing part 2, the lower mold 3 and the lower pressing part 4 to form a second configuration different from the first configuration, so that the workpiece W is shaped as Molded part W'.

Preferably, the direction of the relative movement is the same, and during the process of transforming from the first configuration to the second configuration, the workpiece W (especially the workpiece W that is forming the molded part W') continues to move with the The upper mold 1, the upper pressing part 2, the lower mold 3 and the lower pressing part 4 are in contact. During the molding process of changing from the first configuration to the second configuration, the workpiece W and the molded part W' have a forming zone (Forming Zone) FZ corresponding to each other. Specifically, the corresponding modules (the first module 11, the second module 21, the third module) in each component (the upper mold 1, the upper pressing part 2, the lower mold 3 and the lower pressing part 4) 31 and the fourth module 41) are used to deform a workpiece W so that the workpiece has a corresponding forming zone FZ.

Preferably, during the molding process in which the above-mentioned first configuration is transformed into the second configuration, corresponding to the main molding zone FZ, at least one of the modules (11, 21, 31, 41) is configured with a corresponding heating unit ( 12, 22, 32, 42). Specifically, as shown in Figure 8, when the upper mold 1, the upper pressing part 2, the lower mold 3 and the lower pressing part 4 initially compress the workpiece W, especially the workpiece W has not yet been deformed. When , 21, 31, 41), the temperature of the contact area (that is, corresponding to the forming zone FZ) increases.

Taking the conventional molding mold without a heating unit (as shown in Figures 1 and 2) as an example, the conventional molding mold is prone to poor formability of the workpiece W, and is prone to deformation in the corresponding deformation area (as shown in Figure 3). portion 92) is damaged, cracked or broken, or the mechanical properties of the corresponding deformation area are deteriorated (for example, stress concentration). Furthermore, even if the conventional technology has the technology of preheating a workpiece W in advance, or the technology of heating the entire forming mold 8 together, heating other positions in the non-forming zone FZ will consume more energy in the heating process. And it is more time-consuming; in addition, heating the entire workpiece W will deteriorate the overall mechanical strength of the workpiece W, especially the strength of all locations of the workpiece W.

In other words, through this case, the upper mold 1, the upper pressing part 2, the lower mold 3 and the Some or all modules (11, 21, 31, 41) of any one of the lower pressing parts 4 have corresponding heating units (12, 22, 32, 42), so that corresponding heating units (12, 22, 32, 42, The molding zone FZ of the workpiece W contacted by the module (11, 21, 31, 41) of 42) has better formability, which can avoid stress concentration, damage, cracks or fractures in the corresponding molding zone FZ, and can avoid the workpiece W The overall mechanical strength is deteriorated; in addition, since only a part of the mold is provided for heating, the heating efficiency can be improved and energy consumption can be reduced.

It should be noted that the number of modules (11, 21, 31, 41) of each component (1, 2, 3, 4) can be set according to actual needs; preferably, each module (11, 21, 31 , 41) The number is at least two; wherein, when the number is two, it is applicable to long workpieces; when the number is three, it is applicable to workpieces with three corners; when the number is When the number is four, it is applicable to workpieces with four corners; however, the present invention is not limited to the above examples. For example, as shown in Figure 10 (and taking Figure 7 as the basis for comparison), it shows another embodiment of the first module 11 / third module 31 and the second module 21 / fourth module 41 . Among them, the upper mold 1 and the upper pressing member 2 can respectively have eight first modules 11 and eight second modules 21. Some of the first modules 11 have heating units 12, and some of the second modules 21 have heating units 12. Some of them have heating units 22. In particular, the heating units 12 and 22 are respectively arranged on the first modules 11 and the second modules 21 with corners. Similarly, the lower mold 3 and the lower pressing member 4 can also have eight third modules 31 and eight fourth modules 41 respectively. Some of the third modules 31 have heating units 32, and the fourth modules 41 Some of them have heating units 42. In particular, the heating units 32 and 42 are respectively disposed on the third modules 31 and the fourth modules 41 with corners.

In a configuration consideration, in order to enable the forming zone FZ to be heated more evenly, each first module 11 , each second module 21 , each third module 31 and each fourth module 41 has a corresponding heating unit. (12, 22, 32, 42).

In another configuration consideration, in order to save energy consumption and maximize heating efficiency, you can The molding zone FZ corresponding to the molded part W' is the inward bend (the position where the inward bend structure is generated). The module is equipped with a heating unit; among them, taking the molded part W' in Figures 8 and 9 as an example, the corresponding molding zone FZ is the inward bend. The modules at are the second module 21 and the third module 31. Alternatively, the heating unit can be provided only where the molding zone FZ of the corresponding molded part W' is an inward bend and is also a corner (for example, the heating unit in Figure 10 is only provided at the corner of the module). Based on the same principle, when the inner bends are in opposite directions, corresponding heating units 12 and 42 can be provided at the positions of the first module 11 and the fourth module 41 .

In another configuration consideration, in order to facilitate the configuration of the heating unit, especially the circuit configuration of the heating unit, the heating unit is preferably a module arranged on the periphery of the integral molding mold; if Figure 10 is taken as an example, then The second module 21 and the third module 31 have corresponding heating units 22 and 32 respectively.

It should be noted that the above configurations of the heating units (12, 22, 32, 42) are only used to illustrate several possible implementations, and the present invention is not limited thereto.

Preferably, the composition of the workpiece W in this case can be a metal, an alloy, or a composite material containing metal or alloy. In one example, the workpiece W is composed of a composite material. The composite material has a three-layer structure. The three-layer structure is composed of aluminum alloy, fiber composite material (prepreg) and aluminum alloy respectively. The corresponding heating unit ( 12, 22, 32, 42) It is better to heat to a temperature above 140°C. In another embodiment, the heating unit (12, 22, 32, 42) can heat between 140°C and 170°C.

According to the structure of the molding mold of the present invention mentioned above, when the workpiece W is to be formed into a molded part W' with other contours, preferably only a local contour is different, the molding mold of the present invention can be replaced by only replacing the component (which can be the upper mold). 1. Modules (first module 11, second module 21, third module 31 and/or fourth module 41) at a local position (at least one of the upper pressing part 2, the lower mold 3 and the lower pressing part 4), To produce molded parts W' with other profiles. For example, as shown in Figures 10 and 11, compared to Figure 10, the molding die in Figure 11 only replaces the first module 11 and 11 at the corners. The second module 21 , the third module 31 and the fourth module 41 . In this way, compared with the conventional technology, the entire molding mold must be replaced. However, the entire mold is bulky, large, and must be re-aligned, which makes replacement inconvenient and time-consuming. The molding mold of the present invention only needs to be partially replaced. The module corresponding to the position is relatively lightweight, small in size, and easy to replace on the replaced object; in addition, the unreplaced module and/or base can be used as a positioning benchmark, which is helpful for alignment during replacement. This can save replacement time.

Preferably, as shown in Figure 12, it shows a partial top view of two adjacent second modules 21. Specifically, at least two of the plurality of second modules 21 are adjacent to each other and each has a protruding portion P extending toward the other. Optionally, there is a gap G between two adjacent protruding parts P. More preferably, when at least one of the plurality of second modules 21 with the protruding portion P expands due to heat, the protruding portion P abuts against another adjacent protruding portion P, so that the two protruding portions P The adjacent protruding parts P form a snapping relationship, so that the deviation between the contour defined between the corresponding second modules 21 and a preset contour is less than a preset deviation value. Similarly (not shown), the adjacent first module 11 , the third module 31 and/or the fourth module 41 may also have corresponding protrusions P respectively, and may also have corresponding gaps G and gaps G. and/or gap G. In other words, adjacent modules may have corresponding protrusions P, and optionally corresponding gaps, so that when the modules expand due to heat, good molding quality can still be maintained.

It should be noted that although the gap G and the protruding portion P are specifically used to compensate for the error caused by thermal expansion of the module with a heating unit, in the case of a module without a heating unit, it can be adjusted by first heating the corresponding The workpiece is then formed using a forming mold to form the heated workpiece, so that the corresponding module will still receive the thermal energy of the heated workpiece and expand. Therefore, the gap G and the protruding portion P can also be applied between modules without a heating unit.

It should be noted that based on the above description, the first module 11 , the second module 21 , the third module 31 and the fourth module 41 can be defined as four different types of modules. Based on the configuration of the gap G corresponding to the heating unit, the corresponding definition is: in the same type of module, with There is a gap G between at least one of the modules of the heating unit and at least one of its adjacent modules. Based on the manner in which the protruding portion P is arranged corresponding to the heating unit, the corresponding definition is: among the modules of the same type, at least two modules are adjacent to each other and each has a protruding portion P extending toward the other, and At least one of the at least two modules has the heating unit. Based on the aspect that the gap G can be arranged between adjacent modules, the corresponding definition is: among modules of the same type, there is a gap between at least one module and at least one of its adjacent modules. Based on the way that the protruding portion P can be arranged between adjacent modules, the corresponding definition is: at least two modules in the same type of modules are adjacent to each other and each has a protruding portion P extending toward the other.

To sum up, the molding mold with detachable modules of the present invention has a plurality of detachable modules (the first module, the second module, and the third module) through the upper mold, the upper pressing part, the lower mold and the lower pressing part respectively. and the fourth module), which can correspond to molded parts with different contours and partially replace the corresponding modules to improve the efficiency of changing molding molds; and there is no need to make and replace the entire molding mold because the molded parts only have local contour differences. It can save the cost of making molds. In addition, some or all modules can have corresponding heating units, which can pre-heat local areas of the workpiece (especially the workpiece molding area) to a certain temperature, thereby improving the molding quality; and by setting heating only in local locations of the forming mold unit, which can improve heating efficiency and reduce energy consumption. In addition, by having gaps (first gap, second gap, third gap and/or fourth gap) between modules, deviations caused by local thermal expansion of the mold can be reduced and molding quality can be improved. In addition, through the protruding portion of the module, the molding mold can still maintain a predetermined contour when it is heated and expands, thereby improving the molding quality.

Although the present invention has been disclosed using the above-mentioned preferred embodiments, they are not intended to limit the invention. Anyone skilled in the art can make various changes and modifications to the above-described embodiments without departing from the spirit and scope of the invention.
