Description

Technical Field

[0001] The utility model relates to the technical field of sheet material processing and forming, in particular to a mold unit of a forming device. The mold unit of the forming device can be applied to the forming device. Background Art

[0002] Molds are tools used in industrial production to make molded objects. They achieve product shape processing by changing the physical state of the material. Molds are composed of various parts. Different molds are composed of different parts. They have specific contours or inner cavity shapes. Products can be manufactured by punching or injecting mold cavity molding. Molds are widely used in punching, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products.

[0003] The forming mold is mainly used to mold the parts to be die-cut (such as cutlery, fork, spoon, disposable paper bowl, etc.) into the required concave and convex shapes, such as paper cutlery, fork, spoon, disposable paper bowl, etc. Take the manufacturing process of paper cutlery as an example, which includes paper lamination, die-cutting, forming and waterproof coating. First, the multi-layer paper is laminated by multiple rollers after gluing; then the main outline is cut out with a rolling cutter; then the mold is used to mold into the concave and convex shape of the cutlery; finally, a layer of waterproof and oil-proof coating is applied on the surface of the formed paper cutlery.

[0004] It can be seen that when the die-cutting parts (such as knives, forks, spoons, disposable paper bowls, etc.) are formed by the mold, the die-cut composite paper is mainly molded into the concave and convex shapes of the knives, forks and spoons by the mold. However, in the prior art, when the mold molds the composite paper into the concave and convex shapes of the knives, forks and spoons, when the mold is die-cutting toward the sheet, the mold is generally connected to multiple guide rods, and the guide rods cooperate with the guide holes to guide the movement of the mold. However, the guiding roles played by the multiple guide rods are independent of each other, but the driving force of the mold for the driving part on the molding device cannot be completely consistent. Since the multiple guide rods are independent of each other, the stroke of the die-cutting surface reaching the die-cutting part during the die-cutting process will be different. For example, one side edge of the die-cutting surface reaches the die-cutting part first, and the other side edge reaches the die-cutting part later. The multiple guide rods cause the die-cutting surface of the mold to be unable to accurately die-cut the die-cutting part, resulting in the die-cut products having different thicknesses and sizes, thereby reducing product quality.

[0005] Therefore, during the operation of the molding die in the prior art, the presence of multiple guide rods causes the die-cutting surface of the mold to be unable to accurately die-cut the workpiece, thereby causing the die-cut products to have different thicknesses and sizes, thereby reducing product quality. Utility Model Content

[0006] During the working process of the molding mold in the prior art, there are multiple guide rods, which causes the die-cutting surface of the mold to be unable to accurately die-cut the workpiece, thereby causing the die-cut products to have different thicknesses and sizes, thereby reducing product quality.

[0007] In view of this, the utility model provides a mold unit of a molding device to solve the above-mentioned problem, wherein the guide member is transmission-connected with the rotating member, and the rotating member always has a limiting locking force on the guide member. Therefore, during the die-cutting process through the mold, the rotation angles of the first rotating member and the second rotating member are always the same, so that the pressing stroke of the mold for the workpiece to be die-cut is consistent, and each position of the die-cutting surface can accurately die-cut the workpiece to be die-cut, so that the thickness of the product die-cut by the molding mold is the same, thereby improving the product quality.

[0008] The utility model adopts the following technical solution to solve the above problems: the mold unit of the molding device comprises a guide assembly fixedly mounted on the frame of the molding device and a mold assembly fixedly connected to one end of the guide assembly.

[0009] The guide assembly includes at least one pair of guide components arranged in pairs on opposite sides of one end wall of the mold assembly, so that when the driving member on the molding device is installed on one end wall of the mold assembly, both sides of the mold can be guided.

[0010] Furthermore, each guiding component includes a guiding member and a rotating member transmission-connected to the side of the guiding member, so that the rotating member always has a locking force on the guiding member; wherein one end of each guiding member is fixed to the end wall of the mold assembly and extends perpendicularly to the end wall of the mold assembly; and, in each pair of guiding components, two rotating members respectively located on the same side of the two guiding members are coaxially arranged, so that the rotation angles of the first rotating member and the second rotating member are always the same.

[0011] By adopting the above technical scheme, when the mold is die-cutting the workpiece to be die-cut (such as a composite paper sheet of a knife, fork and spoon), the guide members on both sides are connected together by the rotating member, and the rotating member always has a limit locking force on the guide member, so that the downward pressing stroke of the mold for the workpiece to be die-cut is consistent, and each position of the die-cutting surface can accurately die-cut the workpiece to be die-cut, thereby making the thickness of the products die-cut by the molding mold the same, thereby improving the quality of the products (such as paper knives, forks and spoons, paper bowls).

[0012] Furthermore, in order to ensure that the locking force of the rotating member on the guide member is more reliable, an embodiment of the mold unit of the molding device is provided, in each guiding component, each guide member is a guide rack perpendicular to one side end wall of the mold assembly, and the guide rack is respectively provided with meshing teeth on both side walls in the width direction of the mold assembly; and the rotating member includes a pair of meshing gears, which are arranged in pairs on both sides of the guide rack in the width direction of the mold assembly, respectively adapted to the meshing teeth on the corresponding side and can rotate along the guide rack in meshing.

[0013] Furthermore, in order to synchronize the rotation angle of each rotating component, in each pair of guiding components, the two meshing gears located on the same side of the two guide racks are at the same height relative to one side end wall of the mold assembly, and the rotating shaft connecting the two meshing gears extends perpendicularly to the two guide racks.

[0014] Furthermore, the utility model also discloses a molding device, which is used for molding and manufacturing disposable cutlery, forks and spoons, and includes the mold unit of the aforementioned molding device. When the cutlery, forks and spoons are produced by the molding device, the rotating member always has a locking force on the guide member, so that in the process of die-cutting the cutlery, forks and spoons to be die-cut by the mold, the rotation angles of the first rotating member and the second rotating member are always the same, so that the pressing stroke of the mold for the cutlery, forks and spoons to be die-cut is consistent, so that the thickness of the cutlery, forks and spoons die-cut by the molding mold is the same, thereby improving the quality of the cutlery, forks and spoons produced.

[0030] The molding mold is mainly used to mold the materials to be molded (such as paper cutlery, disposable paper bowls) into the required concave and convex shapes, such as paper cutlery, disposable paper bowls, etc. Take the manufacturing process of paper cutlery as an example, which includes paper lamination, die-cutting, molding and waterproof coating. First, the multi-layer paper is laminated by multiple rollers after gluing; then the main outline is cut out with a rolling cutter; then the mold is used to mold into the concave and convex shape of the cutlery; finally, a layer of waterproof and oil-proof coating is applied on the surface of the formed paper cutlery.

[0031] It can be seen that when the die-cutting parts (such as cutlery, fork, spoon, disposable paper bowl sheets, etc.) are formed by the mold, the die-cut composite paper is mainly molded into the concave and convex shapes of the cutlery, fork and spoon by the mold. However, in the prior art, when the mold molds the composite paper into the concave and convex shapes of the cutlery, fork and spoon, the mold is generally guided by the guide rod during the movement. However, when the mold is guided by the guide rod, when the mold is punching toward the sheet, the mold is generally connected to multiple guide rods, and the guide rods cooperate with the guide holes to guide the movement of the mold. However, the guiding roles played by the multiple guide rods are independent of each other. However, the driving force of the driving member on the molding device for the mold cannot be completely consistent. Since the multiple guide rods are independent of each other, the stroke of the die-cutting surface reaching the die-cutting part during the punching process of the mold will be different. For example, one side edge of the die-cutting surface reaches the die-cutting part first, and the other side edge reaches the die-cutting part later. The multiple guide rods cause the die-cutting surface of the mold to be unable to accurately die-cut the die-cutting part, resulting in different thicknesses of the die-cut products, thereby reducing product quality.

[0032] In order to solve the above problems, the utility model discloses a mold unit of a forming device, wherein a guide member is transmission-connected with a rotating member, and the rotating member always has a locking force on the guide member. Therefore, during the die-cutting process through the mold, the rotation angles of the first rotating member and the second rotating member are always the same, so that the mold has consistency in the downward stroke for the piece to be die-cut (such as a composite paper sheet of a knife, fork and spoon), and each position of the die-cutting surface can accurately die-cut the piece to be die-cut, so that the thickness of the product die-cut by the forming mold is the same, thereby improving the quality of the product (such as a paper knife, fork and spoon, and a paper bowl).

[0033] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, first, the overall structure of the mold unit 1 of the molding device provided in this embodiment is described.

[0035] The mold unit 1 of the molding device includes: a guide assembly 10 fixedly mounted on the frame of the molding device, and a mold assembly 20 fixedly connected to one end of the guide assembly 10. It should be understood that when the driving end of the driving member on the molding device is connected to the mold assembly 20 and drives the mold assembly 20 to move, the guide assembly 10 has a guiding effect on the mold assembly 20; when the driving member on the molding device does not drive the mold assembly 20 to move, the guide assembly 10 has a locking and limiting effect on the mold assembly 20, thereby avoiding the problem of different die-cutting sizes of the die-cutting pieces to be die-cut (such as composite paper sheets of knives, forks and spoons, and composite paper sheets of paper bowls) caused by shaking of the mold assembly 20 due to inertia.

[0036] Specifically, the guide assembly 10 includes at least one pair of guide components 100 arranged in pairs on opposite sides of the end wall of one side of the mold assembly 20, so that when the driving member on the molding device is installed on the end wall of one side of the mold assembly 20, both sides of the mold can be guided, and when the driving member on the molding device drives the mold assembly to move, the pair of guide components 100 are linked to ensure the consistency of the guidance.

[0037] More specifically, each guide component 100 includes a guide member 101 and a rotating member 102 that is transmission-connected to the side of the guide member 101, so that the rotating member 102 always has a limiting locking force on the guide member 101; wherein one end of each guide member 101 is fixed to the end wall of the mold assembly 20 and extends perpendicular to the end wall of the mold assembly 20; and, in each pair of guide components 100, the two rotating members 102 located on the same side of the two guide members 101 are coaxially arranged, so that the rotation angles of the first rotating member 102 and the second rotating member 102 are always the same.

[0038] In summary, the action process of this mold unit is as follows: when the driving end of the driving member on the molding device is connected to the mold assembly 20 and drives the mold assembly 20 to move and die-cut the pieces to be die-cut (such as cutlery, fork and spoon sheets, paper bowl sheets, etc.), the mold assembly 20 drives the guide member 101 to move and links the rotating member 102 to rotate. Since the rotating member 102 is connected to the side of the guide member 101, when the mold assembly 20 is driven to move, the guide member 101 always has a limit locking force on the mold assembly 20. The driving member on the molding device overcomes the limit locking force and drives the mold assembly 20 to move. Therefore, the downward stroke of the mold assembly 20 is always consistent, and each position of the die-cutting surface of the mold assembly 20 can accurately die-cut the pieces to be die-cut, so that the thickness of the products die-cut by the mold assembly 20 is the same, thereby improving the quality of the products (such as paper cutlery, fork and spoon, paper bowls).

[0039] It should be understood that the guide assembly 10 includes at least one pair of guide components 100 arranged in pairs on opposite sides of the end wall of one side of the mold assembly 20, wherein the number of the guide components 100 can be one pair, two pairs, four pairs, etc., and specific technical personnel in this field can design it according to the size of the mold assembly 20, and this embodiment is not limited here.

[0040] It is further important to understand that Figure 1 and Figure 3 The directions indicated therein are respectively a length direction 40 , a width direction 50 , and a thickness direction 60 of the mold assembly 20 .

[0041] To make the present invention more clear, please refer to Figure 1-Figure 4 The mold unit will be described in detail below by taking an example in which the guide assembly 10 includes a pair of guide components 100 , and the pair of guide components 100 are respectively arranged at the two side ends of the length direction 40 of the mold assembly 20 .

[0042] Alternatively, if Figure 1 and Figure 2As shown, in one embodiment, each guide member 101 in each guide component 100 is configured as a guide rack 1010 perpendicular to one side end wall of the mold assembly 20, and the guide rack 1010 is respectively provided with meshing teeth on both side walls in the width direction 50 of the mold assembly 20. In addition, the rotating component 102 includes a pair of meshing gears 1020, one of the meshing gears 1020 is arranged on one side of the guide rack 1010 in the width direction 50 of the mold assembly 20, and the other meshing gear 1020 is arranged on the other side of the guide rack 1010 in the width direction 50 of the mold assembly 20, and the pair of meshing gears 1020 are respectively adapted to the meshing teeth on the corresponding side of the guide rack 1010, and by setting a pair of meshing gears 1020 to mesh with the guide rack 1010, the limit locking force of the pair of meshing gears 1020 on the guide rack 1010 is made greater, and the downward stroke of the mold assembly 20 is further made to remain consistent, thereby avoiding the problem that the guide rack 1010 is deformed due to the pressure of the mold assembly 20 on the guide rack 1010, thereby reducing the limit locking force, and making the reliability of the guide assembly 10 higher. Furthermore, when the mold assembly 20 moves, driving the guide rack 1010 to move, the pair of meshing gears 1020 can mesh and rotate along the guide rack 1010. It should be understood that when the pair of meshing gears 1020 can mesh and rotate along the guide rack 1010, the position of the meshing gears 1020 remains unchanged, and the guide rack 1010 is driven by the mold assembly 20 to perform a translational motion along its height direction.

[0043] Optionally, the rotating member 102 may also include two pairs of meshing gears 1020 , three pairs of meshing gears 1020 , etc. Those skilled in the art may design according to their own needs, and this embodiment is not limited here.

[0044] Alternatively, if Figure 1 and Figure 2 As shown, in an achievable embodiment, in each guide component 100 of a pair of guide components 100, two meshing gears 1020 located on the same side of two guide racks 1010 are at the same height relative to one side end wall of the mold assembly 20, so that the limiting locking force of the meshing gears 1020 on the guide racks 1010 is at the same position of the guide racks 1010 in the width direction 50 of the mold assembly 20, thereby ensuring the reliability of the guide component 100 limiting the mold assembly 20 during movement. In addition, the rotation axis 1031 connecting the two meshing gears 1020 extends perpendicularly to the two guide racks 1010.

[0045] Optionally, in a feasible implementation, as Figure 1 and Figure 3As shown, each guide component 100 in a pair of guide components 100 also includes a component bracket 30 fixedly mounted on the frame of the molding device, the component bracket 30 includes a base 310 mounted on the frame of the molding device, and a shell 300 detachably fixed to the base 310, and the base 310 and the shell 300 are surrounded to form a receiving space, the guide rack 1010 extends through the base 310 and the shell 300 along the thickness direction 60 of the mold assembly 20, and the rotating member 102 is rotatably arranged in the receiving space and the shell 300.

[0046] Specifically, by rotatably arranging the rotating member 102 in the accommodation space, when the rotating member 102 rotates during the operation of the mold unit, the housing 300 can prevent the staff from accidentally touching the rotating member 102. By arranging the base 310 to be detachably connected to the housing 300, it is convenient to open the housing 300 to repair the rotating member 102 later.

[0047] Optionally, in a feasible implementation, since a pair of guide components 100 are provided, and the rotating member 102 in each guide component 100 includes a pair of meshing gears 1020 , a pair of rotating shafts 1031 are provided. Among them, one rotating shaft 1031 of a pair of rotating shafts 1031 is arranged along the length direction 40 of the mold assembly 20, one end passes through one meshing gear 1020 of a pair of meshing gears 1020 of one guide component 100 and is rotatably connected to the outer side wall of the shell 300 of one guide component 100, and the other end passes through one meshing gear 1020 of a pair of meshing gears 1020 of another guide component 100 and is rotatably connected to the outer side wall of the shell 300 of the other guide component 100; the other rotating shaft 1031 of the pair of rotating shafts 1031 is arranged along the length direction 40 of the mold assembly 20, one end passes through the other meshing gear 1020 of a pair of meshing gears 1020 of one guide component 100 and is rotatably connected to the outer side wall of the shell 300 of one guide component 100, and the other end passes through the other meshing gear 1020 of a pair of meshing gears 1020 of another guide component 100 and is rotatably connected to the outer side wall of the shell 300 of the other guide component 100. Furthermore, the connection between the rotating shaft 1031 and the meshing gear 1020 is fixedly connected. That is, both ends of the rotating shaft 1031 pass through the corresponding meshing gear 1020 and are rotatably disposed on the outer side wall of the component bracket 30 on the corresponding side.

[0048] Specifically, since the rotating shaft 1031 is fixedly connected to the meshing gear 1020 of one guide component 100 and the meshing gear 1020 of the other guide component 100 in a pair of guide components 100, when the driving member of the molding device drives the mold assembly 20 to move and the guide rack 1010 is linked to move, and the guide rack 1010 is linked to the meshing gear 1020 to rotate, the rotation angles of the meshing gears 1020 fixedly connected by the rotating shaft 1031 in the pair of guide components 100 are consistent, so that the limiting locking forces of the pair of guide components for the mold assembly 20 are synchronized with each other, thereby ensuring that the downward stroke of the mold assembly 20 on both sides is always consistent, and then the thickness of the products die-cut by the mold assembly 20 is the same, thereby improving the quality of the products (such as paper cutlery, fork, spoon, paper bowl).

[0049] like Figure 3 and Figure 4 As shown, the structure and arrangement of the mold assembly 20 are further explained below.

[0050] In one feasible embodiment, the mold assembly 20 includes a mold part 200 and a connecting seat 210 stacked in a thickness direction 60 , and the mold part 200 and the connecting seat 210 are detachably connected together, so that different mold parts 200 can be replaced when producing different products.

[0051] Specifically, a pair of guide components 100 are arranged on the side end wall of the connection seat 210 away from the mold component 200, and a driving connection component 220 that is transmission-connected to the driving component of the molding device is also arranged on the side end wall of the connection seat 210. By setting the driving connection component 220, it is convenient to connect the driving end of the driving component of the molding device to the connection seat 210. When working, the driving component drives the connection seat 210 to move and links the mold component 200 to move. It should be understood that the driving component of the molding device can be a driving cylinder, a driving oil cylinder, an electric telescopic rod, etc. arranged on the molding device, and this embodiment is not limited here. More specifically, in order to ensure that the driving force of the driving component of the molding device on the mold assembly 20 is uniform, a plurality of driving connections 220 can be arranged on the connection seat 210 at intervals along the length direction 40 of the mold assembly 20, such as 2, 3, 4, etc.

[0052] Optionally, in a feasible embodiment, two driving connectors 220 can be spaced apart on the connecting seat 210 along the length direction 40 of the mold assembly 20, and the driving members of the molding device are configured as two driving cylinders, and the driving ends of the two driving cylinders respectively correspond one-to-one to the two driving connectors 220 and are transmission-connected, and a pair of guide components 100 are spaced apart along the length direction of the mold assembly 20 on opposite sides of the end wall of one side of the connecting seat 210 away from the mold component 200. When the two driving cylinders drive the mold assembly 20 to move, even if the driving forces of the two driving cylinders on the mold assembly 20 are different, since each of the pair of guide components 100 includes a guide member 101 and a rotating member 102 that is transmission-connected to the side of the guide member 101, the rotating member 102 always has a limiting locking force on the guide member 101, and the moving stroke of each guide member 101 is kept consistent by setting the rotating shaft 1031, thereby ensuring that the downward pressing stroke of the mold assembly 20 remains consistent and the operation process is smooth. Each position of the die-cutting surface of the mold assembly 20 can accurately and smoothly die-cut the die-cut piece, thereby making the thickness of the products die-cut by the mold assembly 20 the same, thereby improving the quality of the products (such as paper cutlery, fork, spoon, paper bowl).

[0053] It should be understood that the guide component 100 and the drive connector 220 are located on the same side end wall of the connecting seat 210, and the drive connector 220 can be a snap-on seat, a connecting port, etc. arranged on the side end wall of the connecting seat 210, which is not limited in this embodiment.

[0054] Optionally, in a feasible implementation, as Figure 3 and Figure 4 As shown, the mold component 200 is configured as a mold base 2001, and a plurality of cutters 2002 are evenly spaced along the length direction 40 of the mold assembly 20 on the side of the mold base 2001 away from the connecting base 210, so that when the mold unit is working, the mold assembly 20 can simultaneously die-cut a plurality of pieces to be die-cut, thereby improving the working efficiency of the mold assembly 20. It should be understood that the die-cutting surface of the mold assembly 20 is located on the side of the mold base 2001 away from the connecting base 210; the number of the cutters 2002 can be 5, 8, 10, etc., which is not limited in this embodiment.

[0055] Specifically, the shape of the cutting knife 2002 should be the same as the shape of the product to be produced. For example, when producing a knife, fork and spoon, the shape of the cutting knife 2002 is the shape of a knife, fork and spoon, which is not limited in this embodiment.

[0056] Optionally, in a feasible implementation, in order to reduce the power of the driving member on the molding device, a plurality of evenly spaced weight-reducing grooves 2101 are provided on the end wall of the connecting seat 210 away from the mold component 200, and by providing the weight-reducing grooves 2101, the weight of the mold assembly 20 itself can be reduced, so that the limiting locking effect of the guide rack 1010 and the meshing gear 1020 on the mold assembly 20 is better, and the consistency of the mold's downward pressing stroke for the die-cutting piece is further improved. It should be understood that the number of weight-reducing grooves 2101 can be 2, 4, 5, etc., and this is not limited in this embodiment.

[0057] Furthermore, the utility model also discloses a molding device, which is used for molding and manufacturing disposable knives, forks and spoons, and includes the mold unit 1 of the aforementioned molding device. When the knives, forks and spoons are produced by the molding device, the rotating member 102 always has a locking force on the guide member 101, so that in the process of die-cutting the fork and spoon pieces to be die-cut by the die 2002, the rotation angles of the first rotating member 102 and the second rotating member 102 are always the same, so that the pressing stroke of the mold for the knives, forks and spoons to be die-cut is consistent, and each position of the die-cutting surface can accurately die-cut the knives, forks and spoons to be die-cut, so that the thickness of the knives, forks and spoons die-cut by the molding mold is the same, which improves the quality of the knives, forks and spoons.

[0058] In summary, taking the mold unit 1 of the molding device being applied to the molding device to produce knives, forks and spoons, and the mold assembly 20 including a pair of guide components 100 as an example, the action process of the mold unit is further described.

[0059] When the driving end of the driving member on the molding device is transmission-connected to the driving connecting member 220 on the mold base 2001, and drives the connecting base 210 to move and links the mold component 200 to move to die-cut the die-cut piece, the connecting base 210 drives the guide rack 1010 set on the end wall of one side of the connecting base 210 to move and links the meshing gear 1020 to rotate. Since the meshing teeth on the guide rack 1010 are engaged with the meshing gear 1020, during the movement of the mold component 200, the guide rack 1010 always applies a limit locking force to the connecting base 210. The driving member on the molding device overcomes the limit locking force to drive the connecting base 210 to move and links the mold component 200 to move, thereby die-cutting the die-cut piece. Since the guide rack 1010 always applies a limit locking force to the connecting seat 210, and the rotating shaft 1031 makes the rotation angle of the meshing gear 1020 connected by the rotating shaft 1031 in a pair of guide components 100 always the same, the downward stroke of the mold assembly 20 always remains consistent, so that the thickness of the product die-cut by the mold assembly 20 is the same, thereby improving the quality of the product (such as paper cutlery, fork, spoon, paper bowl).

[0060] The above is an explanation of the implementation mode of the present invention by specific specific embodiments. Those skilled in the art can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this utility model are limited to this implementation mode. On the contrary, the purpose of introducing the utility model in conjunction with the implementation mode is to cover other options or modifications that may be extended based on the claims of the present utility model. In order to provide a deep understanding of the present utility model, the above description will include many specific details. The present utility model can also be implemented without using these details.
