Description

Technical Field

[0001] The invention relates to the technical field of molds, and in particular to a frame molding mold and a molding process. Background Art

[0002] Frame products can be used as shells and are a type of product that is widely used. Existing frame products can be prepared by drawing devices. This method usually requires rolling the sheet into a round tube first, and then drawing it multiple times. The process is complicated, the production cycle is long, and the production efficiency is low. In addition, each time the material is drawn, the degree of hardening will increase, and annealing will be required. The more times the drawing is done, the higher the cost. The wall thickness of the product directly obtained by drawing is generally thicker. In order to obtain the required product thickness, laser cutting is usually required to cut the thickness. During the laser cutting process, it is also easy to cause product deformation, which reduces the quality of the product. Summary of the invention

[0008] Wherein, the driving member has a first position and a second position. When the driving member is in the first position, the first driving inclined surface of the shaping module is in contact with the corresponding second driving inclined surface. When the driving member switches from the first position to the second position, the shaping module moves outward, and the first driving inclined surface of the shaping module is disengaged from the corresponding second driving inclined surface.

[0009] In one embodiment of the present invention, the driving member comprises a prism, a pyramid is formed on the upper portion of the prism, and the side surface of the pyramid forms the second driving inclined surface.

[0010] In one embodiment of the present invention, the sliding surface further includes a first sliding plane, the lower portion of the first sliding plane is connected to the first driving inclined plane, and the first sliding plane is used to abut against the side surface of the prism.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] Embodiment 1

[0057] See also Figure 1-Figure 16 This embodiment discloses a frame forming mold, including a driving member 10, a shaping module 20 and a base 30; the moving direction of the driving member 10 relative to the base 30 is a first direction Z, and the moving direction of the shaping module 20 relative to the base 30 is perpendicular to the first direction, that is, each shaping module 20 moves in a plane perpendicular to the first direction (Z direction);

[0058] The base 30 is a fixed part, mainly used to install the driving part 10 and the shaping module 20. The driving part 10 and the shaping module 20 are both movable parts, and can move relative to the base 30.

[0059] like Fig.10 As shown, a plurality of second driving inclined surfaces 101 are formed on the upper portion of the driving member 10, and the second driving inclined surfaces 101 are arranged obliquely relative to the first direction, and all the second driving inclined surfaces 101 are arranged around the outer periphery of the driving member 10. Specifically, all the second driving inclined surfaces 101 are arranged circumferentially around the axis of the driving member 10;

[0060] like Fig. 9 As shown, the shaping module 20 includes a shaping portion 201 and a push-pull portion 202, the shaping portion 201 includes a shaping surface 2011 and a connecting surface 2012, one end of the push-pull portion 202 is connected to the connecting surface 2012 of the shaping portion 201, and the other end is provided with a sliding surface 2021 that can slide along the driving member 10, the sliding surface 2021 includes a first driving inclined surface 20211, and the first driving inclined surface 20211 of each shaping module 20 corresponds to the second driving inclined surface 101 one by one, and the first driving inclined surface 20211 of each shaping module 20 can slide along the corresponding second driving inclined surface 101;

[0061] A main body sliding cavity 301 for the driving member 10 to slide is formed inside the base 30, and a slot 302 is provided on the side wall of the base 30. The slot 302 is connected to the main body sliding cavity 301, and the slot 302 corresponds to the push-pull portion 202 of the shaping module 20 one by one. The push-pull portion 202 of each shaping module 20 can be slidably connected to the corresponding slot 302. The shaping surfaces 2011 of all shaping modules 20 on the base 30 are enclosed in the first shape, that is, the shaping surfaces 2011 are connected end to end to enclose the first shape, such as Figure 1 , Figure 4 and Figure 8 As shown, the shaping surfaces 2011 of all shaping modules 20 on the base 30 are enclosed in a rectangular shape;

[0062] The driving member 10 has a first position and a second position, see Figure 1-Figure 5 When the driving member 10 is in the first position, the first driving inclined surface 20211 of the shaping module 20 contacts the corresponding second driving inclined surface 101. When the driving member 10 switches from the first position to the second position, Figure 11-13 , the shaping module 20 moves outward, and the first driving inclined surface 20211 of the shaping module 20 is separated from the corresponding second driving inclined surface 101.

[0063] The above structure can make the first driving inclined surface 20211 slide relative to the corresponding second driving inclined surface 101 by pushing and pulling the driving member 10, so that the shaping module 20 can move outward relative to the base 30. The moving shaping module 20 can push against the external blank, thereby causing the external blank to deform and finally form into a frame-type product with the first shape.

[0064] Among them, the shape formed by the molding surfaces 2011 of all the molding modules 20 on the base 30 - the first shape determines the shape of the final formed frame 50. The first shape can be changed by changing the shape of the molding surfaces 2011, thereby obtaining frame products of different shapes.

[0065] In some embodiments, Figure 6 and Fig.10 As shown, the driving member 10 includes a prism 102 , a pyramid 103 is formed on the upper portion of the prism 102 , and a side surface of the pyramid 103 forms a second driving inclined surface 101 .

[0066] Furthermore, the prism 102 and the pyramid 103 have the same number of side edges. For example, if the prism 102 is a quadrangular prism, then the pyramid 103 is a quadrangular pyramid, which is easier to arrange and helps to better control the movement direction of the shaping module 20.

[0067] The prism 102 may be in the shape of a quadrangular prism, a hexagonal prism, an octagonal prism or other multi-prisms, and the corresponding pyramid 103 may be in the shape of a quadrangular pyramid, a hexagonal pyramid, an octagonal pyramid or the like.

[0068] In this embodiment, the prism 102 of the driving member 10 is a quadrangular prism, the pyramid 103 is a quadrangular pyramid, there are four second driving inclined surfaces 101 and four shaping modules 20 , and each shaping module 20 corresponds to one second driving inclined surface 101 .

[0069] In some embodiments, the sliding surface 2021 further includes a first sliding surface 20212, and the lower portion of the first sliding surface 20212 can be obtained by beveling to obtain a first driving inclined surface 20211, and the first sliding surface 20212 is used to abut against the side surface of the prism 102. When the driving member 10 switches from the first position to the second position, the shaping module 20 moves outward, and the first driving inclined surface 20211 of the shaping module 20 is separated from the corresponding second driving inclined surface 101, and at this time, the first sliding surface 20212 moves to abut against the corresponding side surface of the prism 102.

[0070] It can be understood that when the prism 102 is a quadrangular prism, the prism 102 has four side surfaces, each of which corresponds to a first sliding plane 20212 of the shaping module 20 . When sliding to a certain position, each first sliding plane 20212 contacts the corresponding side surface of the prism 102 .

[0071] The provision of the first sliding plane 20212 is more conducive to ensuring the movement stability of the shaping module 20.

[0072] The connection surface 2012 may be a plane, and the connection surface 2012 and the first sliding plane 20212 are parallel to each other, so as to facilitate improving the connection stability.

[0073] In some embodiments, Fig. 9 As shown, the thickness H1 of the shaping portion 201 along the first direction is not less than the thickness H2 of the push-pull portion 202 along the first direction, that is, H1≥H2. On the one hand, this method makes the thickness of the shaping portion 201 thicker, which is more conducive to improving the stability of the molding process and meeting the depth requirements of different molded parts. The thickness of the push-pull portion 202 is relatively small, which can reduce the overall weight of the shaping module 20, reduce its driving force, and make its movement more flexible.

[0074] In some embodiments, Fig.10 As shown, the inclination angle α of the second driving inclined surface 101 relative to the first direction Z is 2° to 88°. The above inclination angle determines the outward movement stroke of the shaping module 20 and can be selected according to actual needs.

[0075] In some embodiments, the inclination angle of the second driving inclined surface 101 relative to the first direction may be 30° to 60°.

[0076] Preferably, the inclination angle of the second driving inclined surface 101 relative to the first direction is 45°.

[0077] In some preferred embodiments, the axis of the driving member 10 coincides with the axis of the main body sliding cavity 301 to ensure the smoothness of the movement of the driving member 10 .

[0078] In some embodiments, Figure 7 As shown, the base 30 is also provided with a plurality of auxiliary parts 303 arranged in a circumferential direction, and a receiving space 304 is formed between two adjacent auxiliary parts 303. A shaping part 201 is placed in each receiving space 304. An auxiliary surface 3031 is formed on each auxiliary part 303, and the auxiliary surface 3031 is used to abut against the inner wall of the finally formed frame 50. The auxiliary surface 3031 plays an auxiliary shaping role in the shaping process, which is more conducive to ensuring the accuracy of the shape of the final frame 50. For example, there are four shaping modules 20, each of which has an L-shaped shaping surface 2011. During the final shaping, the auxiliary surface 3031 of each auxiliary part 303 is on the same plane as the partial side surfaces of the shaping surface 2011 on both sides, thereby better ensuring the flatness of each side surface of the final frame.

[0079] It is understandable that in some other embodiments, the auxiliary part 303 may not be provided.

[0080] In some embodiments, the slot 302 may be an open slot or a closed channel without a bottom opening.

[0081] It is understandable that when the above-mentioned slot 302 is an open slot with an opening at the bottom, the mold should be placed on a workbench when in use, so that the bottom surface of the base 30 is supported by the workbench to prevent the molding module 20 from falling from the base 30.

[0082] In this embodiment, the first shape is a rectangle, and a rectangular frame 50 or the like product can be obtained by the above-mentioned mold.

[0083] In this embodiment, if Figure 1 As shown, the mold has a driving member 10, four shaping modules 20 and a base 30. The prism 102 in the driving member 10 is a quadrangular prism, and the pyramid 103 is a quadrangular pyramid. At this time, the shaping surface 2011 of each shaping module 20 is L-shaped, and the shaping surfaces 2011 of the four shaping modules 20 are enclosed in a rectangular shape. Taking this mold as an example, the molding process of the rectangular frame 50 is specifically described:

[0084] The molding process of the rectangular frame 50 (see Figure 14-16), including the following steps:

[0085] 1) If Figure 1 and Fig.14 As shown, the tubular blank 40 is sleeved on the outside of the forming mold, so that all four shaping modules 20 are located inside the tubular blank 40, and the driving member 10 is located in the first position. In the first position, the first driving inclined surface 20211 of each shaping module 20 is in contact with the corresponding second driving inclined surface 101 on the driving member 10;

[0086] Wherein, the tubular blank 40 is a round tube-shaped blank;

[0087] 2) The driving member 10 is pushed to move upward in the main sliding cavity 301 of the base 30 along the first direction, so that the first driving inclined surface 20211 slides along the corresponding second driving inclined surface 101 to push each shaping module 20 to move outward, so that the shaping surface 2011 of each shaping module 20 abuts against the tubular blank 40 and gradually pushes and pulls the tubular blank 40 outward to deform it. In this process, the tubular blank 40 gradually fits on the shaping surface 2011 of each shaping module 20, as shown in FIG. Figure 11-13 ,as well as Figure 14-15 As shown, the shape of the blank gradually approaches the first shape, i.e., a rectangle, until it is finally completely deformed into a rectangular frame 50 , thereby realizing the conversion from the circular tube-shaped blank to the rectangular frame 50 .

[0088] For further information, see Figure 11-13 When a rectangular frame 50 is obtained, the shaping surfaces 2011 of each shaping module 20 are in contact with the inner wall of the frame 50 .

[0089] If the base 30 is further provided with auxiliary parts 303, then during the molding process of the frame body 50, a portion of the tubular blank 40 is gradually attached to the auxiliary surfaces 3031 of the auxiliary parts 303 (see FIG. Figure 11-13 ), thereby obtaining a rectangular frame product with higher precision.

[0090] It can be understood that if the size of the rectangular frame to be formed is small, then each shaping module 20 can be moved a small distance to the outside. At this time, the first driving slope 20211 only needs to slide along the corresponding second driving slope 101 to a smaller displacement without sliding out of the second driving slope 101; if the size of the rectangular frame to be formed is large, then each shaping module 20 needs to be moved a large distance to the outside. At this time, the first driving slope 20211 needs to slide along the corresponding second driving slope 101 and finally slide out of the second driving slope 101, so that the first sliding plane 20212 of the sliding surface 2021 moves to contact the corresponding side of the driving member 10. At this time, the driving member 10 moves to the second position, and the distance moved to the outside by each shaping module 20 is the maximum distance.

[0091] The use of the mold of this embodiment to prepare the frame product greatly simplifies the preparation process of the frame product. Compared with the traditional drawing process, there is no need for repeated drawing and annealing operations, and the frame product can be formed in one time. The frame product with thinner wall thickness can be directly prepared. The thinnest wall thickness can reach 0.04 mm, which is 1 / 5 of the wall thickness that can be achieved by the conventional drawing process.

[0092] In addition, by using the mold of this embodiment to prepare the frame product, it is possible to obtain a frame product without an R angle or with a smaller R angle (the R angle refers to the rounded corner formed by the intersection of the edge of the product or two planes, such as Fig.16 The R angle of the frame products is 501), while the R angle of the molded products obtained by the traditional drawing process is larger, and the smallest R angle is 10 to 15 times the material thickness;

[0093] The frame product is prepared using the mold of this embodiment, and the process is simple. It not only improves production efficiency, but also is more conducive to improving the dimensional accuracy and quality of the product, while also greatly reducing production costs. It has high versatility and can be used alone or in conjunction with other equipment to prepare frame products of various complex shapes.

[0094] Embodiment 2

[0095] See also Figure 17-Figure 19 The main difference between this embodiment and the first embodiment is that in this embodiment, only two shaping modules 20 need to be placed, the prism body 102 in the driving member 10 adopts a quadrangular prism, the pyramid body 103 adopts a quadrangular pyramid, and there are four second driving inclined surfaces 101 in total. Only the shaping modules 20 need to be correspondingly configured at the two second driving inclined surfaces 101 that are oppositely arranged.

[0096] The molding surfaces 2011 of the two molding modules 20 are both semicircular, and the molding surfaces 2011 of the two molding modules 20 arranged opposite to each other enclose an oblong shape. An oblong frame product can be prepared by the mold, and the molding process is as follows (see Fig.17 ):

[0097] 1) The tubular blank 40 is sleeved on the outside of the forming mold so that both shaping modules 20 are located inside the tubular blank 40 and the driving member 10 is located at a first position. In the first position, the first driving inclined surface 20211 of each shaping module 20 is in contact with the corresponding second driving inclined surface 101 on the driving member 10;

[0098] Wherein, the tubular blank 40 is a round tube-shaped blank;

[0099] 2) Push the driving member 10 to move upward along the first direction in the main sliding cavity 301 of the base 30, so that the first driving inclined surface 20211 slides along the corresponding second driving inclined surface 101 to push each shaping module 20 to move outward, so that the shaping surface 2011 of each shaping module 20 abuts against the tubular blank 40 and gradually pushes and pulls the tubular blank 40 outward to deform it. In this process, the tubular blank 40 gradually fits on the shaping surface 2011 of each shaping module 20, and its shape gradually approaches the first shape-oblong, until it is finally completely deformed into an oblong frame 50, thereby realizing the conversion from a round tubular blank to an oblong frame 50.

[0100] When the oblong frame 50 is formed, the mold state is referred to Fig.18 .

[0101] Similarly, see Figure 20-21 If the molding surfaces 2011 of the two molding modules 20 are both rectangular, the molding surfaces 2011 of the two relatively arranged molding modules 20 enclose a rectangle, and a rectangular frame product can be prepared by the mold, which will not be described in detail here.

[0102] Embodiment 3

[0103] See also Figure 22-Figure 23 The main difference between this embodiment and the first embodiment is that the present embodiment still has four shaping modules 20, but the shape of the shaping surface 2011 of each shaping module 20 is different from that of the first embodiment.

[0104] The shaping surfaces 2011 of the four shaping modules 20 enclose a parallelogram, and a parallelogram frame product can be prepared using this mold. The specific process steps are roughly the same as those in the first embodiment and will not be repeated here.

[0105] Embodiment 4

[0106] See also Figure 24-25 The main difference between this embodiment and the first embodiment is that the present embodiment still has four shaping modules 20, but the shape of the shaping surface 2011 of each shaping module 20 is different from that of the first embodiment.

[0107] The shaping surfaces 2011 of the four shaping modules 20 are enclosed in a trapezoidal shape, and a trapezoidal frame product can be prepared using this mold. The specific process steps are roughly the same as those in the first embodiment and will not be repeated here.

They are all within the protection scope of this application and will not be described one by one here.

[0109] It should be noted that the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
