[0035] Figure 1 Figure 1 is a schematic cross-sectional view of a molded component. Figure 1 As shown, a plurality of molding units 02 are arranged on the molding beam 01, and the molding units 02 can be used for molding products. Positioning blocks 03 are arranged between the molding units 02, and the positioning blocks 03 can position the molding units 02 to form products of specific shapes. However, the positioning blocks 02 between the molding units are arranged at intervals, occupying a large space, which is not conducive to improving the efficiency of the molding assembly.

[0036] The embodiment of the utility model provides a forming assembly and a filling device. The forming assembly includes a crossbeam, a plurality of forming arm groups and a plurality of first positioning block groups. The crossbeam extends along a first direction, and a plurality of forming arm groups are arranged on the crossbeam along the first direction. Each forming arm group includes two forming arms that are arranged opposite to each other along the first direction and can be driven to approach or move away from each other. A plurality of first positioning block groups are installed on the crossbeam and are arranged one by one corresponding to the plurality of forming arm groups. Each first positioning block group includes two first positioning blocks that are respectively arranged on both sides of the forming arm group in abutment along the first direction. The two first positioning blocks between two adjacent forming arm groups are overlapped in the second direction, and the second direction is perpendicular to the first direction.

[0037] In the molding assembly provided in the embodiment of the utility model, by overlapping the two first positioning blocks between two adjacent molding arm groups in the second direction, the space occupied by the two first positioning blocks in the first direction can be reduced. Thus, in the first direction, more molding arm groups can be arranged to improve the production efficiency of the molding assembly, or, in the first direction, the space occupied by the molding assembly can be reduced to save space.

[0038] The molding assembly and filling equipment provided by the embodiment of the utility model are described in detail below with reference to the accompanying drawings.

[0039] An embodiment of the utility model provides a molding component. Figure 2 A structural schematic diagram of a molding assembly provided in an embodiment of the utility model; Figure 3 for Figure 2 The schematic diagram of the partial structure of the molding component shown in FIG. Figure 2 and Figure 3 As shown, the forming assembly 100 includes a crossbeam 110, a plurality of forming arm groups 120 and a plurality of first positioning block groups 130. The crossbeam 110 extends along a first direction X, and a plurality of forming arm groups 120 are arranged on the crossbeam 110 along the first direction X. Each forming arm group 120 includes two forming arms 121 arranged opposite to each other along the first direction X and can be driven to approach or move away from each other. The plurality of first positioning block groups 130 are mounted on the crossbeam 110, and the plurality of first positioning block groups 130 are arranged one by one corresponding to the plurality of forming arm groups 120. Each first positioning block group 130 includes two first positioning blocks 131 respectively arranged on both sides of the forming arm group 120 along the first direction X. The two first positioning blocks 131 between two adjacent forming arm groups 120 are arranged overlapping in the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0040] The figure schematically shows that eight first positioning block groups 130 are arranged in a one-to-one correspondence with eight forming arm groups 120, and one forming arm group 120 is arranged in a corresponding manner with one first positioning block group 130. The embodiment of the utility model does not limit the number of first positioning block groups and forming arm groups, and the number of first positioning block groups and forming arm groups can be designed according to actual needs.

[0041] It should be noted that, in the present invention, two adjacent forming arm groups refer to the two forming arm groups without a forming arm group, however, a structure other than the forming arm group may be provided between the two adjacent forming arm groups, for example, a positioning block may be provided. In the present invention, the two first positioning blocks are arranged overlapping in the second direction, which means that the orthographic projections of the two first positioning blocks on the plane perpendicular to the second direction are overlapping.

[0042] In the molding assembly provided by the embodiment of the utility model, by making the two first positioning blocks between two adjacent molding arm groups overlap in the second direction, the space occupied by the two first positioning blocks in the first direction can be reduced, and the size occupied by the two first positioning blocks in the first direction is less than the sum of the sizes of the two first positioning blocks in the first direction. Therefore, more molding arm groups can be arranged in the first direction to improve the production efficiency of the molding assembly, or, in the first direction, the space occupied by the molding assembly can be reduced to save space.

[0043] For example, Figure 3 As shown, the dimensions of the two first positioning blocks 131 in the first direction X are both L1, and by overlapping the two first positioning blocks 131 between two adjacent forming arm groups 120 in the second direction Y, the dimension occupied by the two first positioning blocks 131 in the first direction X is L0<2L1.

[0044] In some examples, such as Figure 3 As shown, the overlapping area of ​​the two first positioning blocks 131 between two adjacent forming arm groups 120 in the second direction Y is greater than or equal to half the area of ​​one of the mutually opposite side walls 1311 of the two first positioning blocks 131. Thus, the two first positioning blocks 131 can have a larger overlapping area in the second direction Y, so that the size occupied by the two first positioning blocks 131 in the first direction X is smaller.

[0045] For example, by making the two first positioning blocks have a larger overlapping area in the second direction, the size L0≤L1 occupied by the two first positioning blocks in the first direction.

[0046] For example, the overlapping area of ​​the two first positioning blocks between two adjacent forming arm groups in the second direction is greater than or equal to four fifths of the area of ​​one of the side walls of the two first positioning blocks that are opposite to each other.

[0047] For example, Figure 3 As shown, the crossbeam 110 includes a first surface S1 , a plurality of first positioning block groups 130 are disposed on the first surface S1 , and the second direction Y is parallel to the first surface S1 .

[0048] For example, Figure 3 As shown, the size of the first positioning block 131 in the second direction Y is smaller than the size of the beam 110 in the second direction Y. For example, the size of the first positioning block 131 in the second direction Y is smaller than or equal to half of the size of the beam 110 in the second direction Y.

[0049] Figure 4 for Figure 2 A schematic diagram of the partial structure of the beam shown; Figure 5 for Figure 2The schematic cross-sectional view of the molding assembly shown is along a direction perpendicular to the first direction. Figure 4 and Figure 5 As shown, the crossbeam 110 includes a first surface S1, a plurality of first positioning block groups 130 are arranged on the first surface S1, a first positioning block 131 includes a first guide protrusion 131a, the first surface S1 includes a first guide groove 111, the first guide groove 111 extends along a first direction X, and the first guide protrusion 131a is arranged in the first guide groove 111 so that the first positioning block 131 can move relative to the crossbeam 110 along the first guide groove 111. Through the cooperation of the first guide protrusion 131a and the first guide groove 111, the first positioning block 131 can be moved along the first guide groove 111. For example, the position of the first positioning block 131 can be adjusted so that the forming arm 121 of the forming arm group 120 is limited to a set position.

[0050] In some examples, such as Figure 4 and Figure 5 As shown, the first surface S1 includes a plurality of first guide grooves 111, and one first guide protrusion 131a is arranged corresponding to one first guide groove 111. For example, by arranging one first guide protrusion 131a corresponding to one first guide groove 111, the installation of the first positioning block 131 is facilitated, and the first positioning block 131 is prevented from being installed incorrectly, installed more than once, or missing.

[0051] In some examples, such as Figure 4 and Figure 5 As shown, the plurality of first guide grooves 111 are located on both sides of the first surface S1 along the second direction Y, and the plurality of first guide grooves 111 located on the same side of the first surface S1 are arranged at equal intervals. Thus, not only is the structural design of the molding assembly 100 convenient, but also the intervals of the first positioning blocks 131 located on the same side of the first surface S1 are equal or substantially equal, which is convenient for installation and use, and avoids the position disorder of the first positioning blocks 131.

[0052] In some examples, such as Figure 5 As shown, a direction mark is provided on the first positioning block 131. Thus, the direction mark can facilitate the installation, identification and position adjustment of the first positioning block. For example, the direction mark can be an arrow. For example, the arrow points to the forming arm supported by the first positioning block.

[0053] Figure 6 for Figure 2 The schematic cross-sectional view of the molding assembly shown is parallel to the first surface. Figure 5 and Figure 6As shown, the first positioning block 131 includes a first mounting hole 131b so that the fastener 160 passes through the first mounting hole 131b to fix the first positioning block 131 to the beam 110. The size of the first mounting hole 131b along the first direction X is greater than the size of the first mounting hole 131b along the second direction Y. By providing the first mounting hole 131b on the first positioning block 131, not only can the first positioning block 131 be fixed, but also the first positioning block 131 can be fixed at different positions of the beam 110 along the first direction X.

[0054] Figure 7 for Figure 2 A schematic diagram of a partial structure of the molding assembly shown in another perspective; Figure 8 for Figure 2 The partial structural diagram of the beam from another perspective is shown in FIG. Figure 2 , Figure 7 and Figure 8 As shown, the forming assembly 100 also includes a plurality of second positioning block groups 140. The crossbeam 110 also includes a second surface S2 arranged opposite to the first surface S1, a plurality of first positioning block groups 130 are arranged on the first surface S1, a plurality of second positioning block groups 140 are arranged on the second surface S2, and a plurality of second positioning block groups 140 are arranged one-to-one corresponding to a plurality of forming arm groups 120. Each second positioning block group 140 includes two second positioning blocks 141 respectively arranged on both sides of the forming arm group 120 along the first direction X, and the two second positioning blocks 141 between two adjacent forming arm groups 120 are arranged overlapping in the second direction Y, and the second direction Y is parallel to the first surface S1. The overlapping arrangement of the two second positioning blocks 141 in the second direction Y means that the orthographic projections of the two second positioning blocks 141 on the surface perpendicular to the second direction Y are overlapping.

[0055] Figure 2 The schematic diagram shows that the forming assembly 100 includes 8 forming arm groups 120, 8 first positioning block groups 130 and 8 second positioning block groups 140, and one forming arm group 120 is respectively arranged corresponding to one first positioning block group 130 and one second positioning block group 140. The embodiment of the utility model does not limit the number of the forming arm groups 120, the first positioning block groups 130 and the second positioning block groups 140, and the number can be designed according to actual needs.

[0056] It should be noted that Figure 8 The second surface S2 is schematically shown as being discontinuous. For example, the second surface may also be continuous, and specific reference may be made to the first surface S1, which is not limited in the present invention.

[0057] In the molding assembly provided by the embodiment of the utility model, the first positioning block group can limit the molding arm group to the first extreme position, and the second positioning block group can limit the molding arm group to the second extreme position. Thus, the molding arm group can have two different extreme positions. For example, the product can be molded or preformed by the molding arm group.

[0058] By making the two second positioning blocks between two adjacent forming arm groups overlap in the second direction, the space occupied by the two second positioning blocks in the first direction can be reduced, and the size occupied by the two second positioning blocks in the first direction is smaller than the sum of the sizes of the two second positioning blocks in the first direction. Thus, more forming arm groups can be arranged in the first direction to improve the production efficiency of the forming assembly, or, in the first direction, the space occupied by the forming assembly can be reduced to save space.

[0059] In some examples, such as Figure 7 As shown, the overlapping area of ​​the two second positioning blocks 141 between two adjacent forming arm groups 120 in the second direction Y is greater than or equal to half the area of ​​one of the mutually opposite side walls of the two second positioning blocks 141. Thus, the two second positioning blocks 141 can have a larger overlapping area in the second direction Y, so that the size occupied by the two second positioning blocks 141 in the first direction X is smaller.

[0060] For example, the overlapping area of ​​the two second positioning blocks between two adjacent forming arm groups in the second direction is greater than or equal to four fifths of the area of ​​one of the side walls of the two second positioning blocks that are opposite to each other.

[0061] For example, Figure 7 As shown, the size of the first positioning block 131 in the second direction Y is smaller than the size of the beam 110 in the second direction Y. For example, the size of the first positioning block 131 in the second direction Y is smaller than or equal to half of the size of the beam 110 in the second direction Y.

[0062] Fig. 9 for Figure 2 The schematic cross-sectional view of the molding assembly shown is along a direction perpendicular to the first direction. Figure 8 and Fig. 9As shown, the second positioning block 141 includes a second guide protrusion 141a, the second surface S2 includes a second guide groove 112, the second guide groove 112 extends along the first direction X, and the second guide protrusion 141a is arranged in the second guide groove 112 so that the second positioning block 141 can move relative to the crossbeam 110 along the second guide groove 112. Through the cooperation of the second guide protrusion 141a and the second guide groove 112, the second positioning block 141 can be moved along the second guide groove 112. For example, the position of the second positioning block 141 can be adjusted so that the forming arm 121 of the forming arm group 120 is limited to a set position.

[0063] In some examples, such as Figure 8 As shown, the second surface S2 includes a plurality of second guide grooves 112, and one second guide protrusion 141a is arranged correspondingly to one second guide groove 112. For example, by arranging one second guide protrusion 141a correspondingly to one second guide groove 112, the installation of the second positioning block 141 is facilitated, and the second positioning block 141 is prevented from being installed incorrectly, installed more than once, or missing.

[0064] In some examples, such as Figure 8 As shown, the plurality of second guide grooves 112 are located on both sides of the second surface S2 along the second direction Y, and the plurality of second guide grooves 112 located on the same side of the second surface S2 are arranged at equal intervals. Thus, not only is the structural design of the molding assembly 100 convenient, but also the intervals of the second positioning blocks 141 located on the same side of the second surface S2 are equal or substantially equal, which is convenient for installation and use, and avoids the position disorder of the second positioning blocks 141.

[0065] Fig.10 for Figure 2 The schematic cross-sectional view of the molding assembly shown is perpendicular to the second direction. Fig.10 As shown, the second positioning block 141 includes a second mounting hole 141b so that the fastener 160 passes through the second mounting hole 141b to fix the second positioning block 141 to the beam 110. The size of the second mounting hole 141b along the first direction X is greater than the size of the second mounting hole 141b along the second direction Y. By providing the second mounting hole 141b on the second positioning block 141, not only the second positioning block 141 can be fixed, but also the second positioning block 141 can be fixed at different positions of the beam 110 along the first direction X.

[0066] In some examples, such as Fig.10 As shown, a direction mark is provided on the second positioning block 141. Thus, the direction mark can facilitate the installation, identification and position adjustment of the second positioning block. For example, the direction mark can be an arrow. For example, the arrow points to the forming arm supported by the second positioning block.

[0067] In some examples, such as Figure 3 and Figure 7 As shown, the orthographic projections of the first positioning block group 130 and the second positioning block group 140 corresponding to the same forming arm group 120 overlap on the first surface S1. Thus, the space occupied by the first positioning block group 130 and the second positioning block group 140 on the beam 110 in the first direction X can be reduced as much as possible, and then, in the first direction X, more forming arm groups 120 can be arranged to improve the production efficiency of the forming assembly 100, or, in the first direction X, the space occupied by the forming assembly 100 can be reduced to save space.

[0068] Fig.11 for Figure 2 A schematic cross-sectional view of a molding component along a direction perpendicular to the second direction. Fig.11 As shown, the two forming arms 121 of the forming arm group 120 are rotatably arranged on the crossbeam 110 around their respective rotation axes 161 so that the two forming arms 121 are moved closer to each other or farther away from each other. For example, the rotation axes 161 of the forming arms 121 can be parallel to the second direction Y. The embodiment of the utility model does not limit the implementation method of the forming arms 121 moving closer to each other or farther away from each other, and it can be achieved by rotation, movement or other methods.

[0069] In some examples, such as Fig.11 As shown, the forming arm 121 penetrates the cross beam 110 along the third direction Z, and the forming arm 121 includes a main body 121a, a finger-shaped portion 121b and a spherical portion 121c. The finger-shaped portion 121b is arranged at one end of the main body 121a, and the spherical portion 121c is arranged at the other end of the main body 121a. The third direction Z is perpendicular to the first direction X and the second direction Y. For example, the main body 121a is rotatably fixed on the cross beam 110. For example, the finger-shaped portion 121b can contact the product to form or preform the product. For example, the spherical portion 121c can move along the cam 150 described later to make the forming arm 121 rotatable.

[0070] like Fig.11 As shown, the first positioning block set 130 is respectively disposed along the first direction X at two sides of the forming arm set 120 so as to have a first distance D1 between the finger portions 121 b of the two forming arms 121 of the forming arm set 120 . Fig.12 for Figure 2 A schematic diagram of the structure in which the forming arm of the forming assembly abuts against the second positioning block. Fig.12As shown, the second positioning block group 140 is respectively disposed on both sides of the two forming arms 121 of the forming arm group 120 along the first direction X so as to have a second distance D2 between the finger-shaped portions 121b of the two forming arms 121 of the forming arm group 120, and the first distance D1 is not equal to the second distance D2. Thus, the two finger-shaped portions 121b of the forming arm group 120 can have two states to form or preform the product. For example, when the forming arm group 120 is in the first extreme position, the finger-shaped portions 121b have a first distance D1 between them. For example, when the forming arm group 120 is in the second extreme position, the finger-shaped portions 121b have a second distance D2 between them.

[0071] For example, Fig.11 and Fig.12 As shown, the first distance D1 is greater than the second distance D2. For example, at the first distance, the product can be transferred between the two fingers of the forming arm group. For example, at the second distance, the product between the two fingers can be formed or preformed.

[0072] In some examples, such as Figure 2 , Fig.11 and Fig.12 As shown, the molding assembly 100 further includes a plurality of cams 150. The plurality of cams 150 are disposed on one side of the beam 110 along the second direction Y, and are disposed one-to-one correspondingly to the plurality of molding arm groups 120.

The embodiment of the utility model does not limit the number of the forming arm groups 120 and the cams 150, and the number can be designed according to actual needs.

[0073] In some examples, such as Fig.11 and Fig.12 As shown, each cam 150 includes two convex surfaces 151 arranged opposite to each other along the first direction X. The crossbeam 110 can rotate around the first direction X so that the spherical parts 121c of the two forming arms 121 of the forming arm group 120 move along the two convex surfaces 151. The main body 121a rotates around its rotation axis 161 under the drive of the spherical parts 121c so that the finger parts 121b of the two forming arms 121 of the forming arm group 120 approach each other or move away from each other. By making the spherical parts 121c move on the convex surface 151 of the cam 150 to drive the main body 121a to rotate, the finger parts 121b are moved closer to each other or away from each other. This structural design makes the transmission efficiency between the various structures in the forming assembly 100 higher, the cooperation is more reliable, and the movement of the finger parts 121b approaching each other or moving away from each other is more stable, so that the formed product has a higher yield rate.

[0074] In some examples, such as Figure 2 As shown, the cross beam 110 can rotate under the action of the transmission belt 162. The embodiment of the utility model is not limited to the method of driving the cross beam 110 to rotate.
