Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping limiting die for a cake cup. Background Art

[0002] A cake cup is a cup-shaped structure used to hold cake batter, and can be roughly divided into paper cake cups, iron cake cups, etc. according to the material. Among them, the iron cake cup is generally formed by stamping a thin plate-like workpiece.

[0003] In the prior art devices, the support and placement of the workpiece to be processed is generally achieved by a receiving table, a deformation groove is opened on the receiving table, and a stamping device and a forming part adapted to the deformation groove are arranged at the upper end of the receiving table. The stamping device is used to move the forming part downward and embed it into the deformation groove, thereby driving the workpiece to be processed to be deformed into the expected equipment.

[0004] However, some prior art devices have a relatively simple structure, and generally use manual loading to complete the placement of the workpiece to be processed. This means that in practice, if there is a lack of corresponding limiting mechanisms, the placement position of the workpiece to be processed is very dependent on the operator's operating proficiency. At the same time, the operator adjusts the position of the workpiece to be processed so that the center axis of the workpiece to be processed coincides with the center axis of the molded part, which will greatly extend the processing time and increase the processing cost.

[0005] Therefore, we believe that we need a stamping limit die that can constrain the position of the workpiece to be processed and ensure that the center axis of the workpiece to be processed coincides with the center axis of the molded part. Summary of the invention

[0006] In view of the deficiencies in the prior art, the utility model proposes a cake cup stamping limit mold, which has the advantages of actively constraining the position of the workpiece to be processed and reducing the processing cost, and solves the shortcomings of the prior art device that lacks a corresponding limit mechanism, relies on the operator's skills, and has high processing costs.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A cake cup stamping limit mold comprises a support plate, a plurality of upper and lower axial support members are arranged around the upper end of the support plate, a receiving plate is commonly arranged on the upper ends of the plurality of support members, a deformation groove is opened at the center position of the receiving plate, a pressure plate is arranged on the upper end of the receiving plate, a forming member is fixedly connected with the lower end of the pressure plate for the deformation groove, a plurality of positioning holes are opened around the pressure plate and pass through the upper and lower ends, a positioning rod with an upper and lower axial direction is inserted in each of the positioning holes, a compression spring I is sleeved on the outer side of the positioning rod, the lower end face of the positioning rod is fixedly connected to the support plate, and the lower end of the compression spring I is fixedly connected to the support plate, a plurality of limit plates are circumferentially arranged on the lower end of the pressure plate, the projection of the limit plate on the horizontal plane coincides with the projection of the receiving plate on the horizontal plane, and a sliding groove is opened on the receiving plate for the limit plate, and the height of the lower end face of the limit plate is less than the height of the lower end face of the forming member.

[0009] Preferably, the limiting plate includes a driving section with a triangular structure in longitudinal section, and a limiting section with a rectangular structure in longitudinal section is fixedly connected to the upper end of the driving section. The height of the upper end surface of the driving section is less than the height of the lower end surface of the molded part, and when the compression spring I is not affected by external force, the height of the lower end surface of the driving section is greater than the height of the upper end surface of the supporting plate.

[0010] Preferably, a plurality of mounting plates having an inverted L-shaped longitudinal section are detachably connected to the lower end surface of the pressure plate in the circumferential direction, and the limiting plate is fixedly connected to the adjacent mounting plates.

[0011] Preferably, each of the limit plates is fixedly connected to an inner rod on one side close to the corresponding mounting plate, an outer tube is sleeved on the outer side of the inner rod, the outer tube is fixedly connected to the corresponding mounting plate, and a compression spring II is sleeved on the outer side of each of the inner rods, and the two axial ends of the compression spring II are respectively abutted against the outer tube and the mounting plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model sets a limit plate at the lower end of the pressure plate, and drives the limit plate through the pressure plate so that when the pressure plate falls, the limit plate can synchronously apply a lateral pushing force to the workpiece to be processed. This can effectively reduce the operation steps, ensure that the center axis of the workpiece to be processed coincides with the center axis of the formed part, and reduce the generation of defective products.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Please refer to Figure 1-5 A cake cup stamping limit mold includes a support plate 1 which plays a major supporting role. In practice, the support plate 1 can be similar to a processing table. In this application, for ease of understanding, it is embodied as the support plate 1.

[0025] A receiving plate 5 is disposed at the upper end of the support plate 1 , and a deformation groove 7 is opened at the center of the receiving plate 5 , so that the deformation trajectory of the workpiece placed on the upper end of the receiving plate 5 is constrained by the deformation groove 7 .

[0026] A pressure plate 6 is provided at the upper end of the receiving plate 5. In practice, the pressure plate 6 can be similar to a corresponding stamping processing equipment. In this application, for ease of understanding, it is embodied as a pressure plate 6.

[0027] A forming part 11 is provided at the lower end of the pressure plate 6, and the forming part 11 fits with the deformation groove 7. In practice, the pressure plate 6 realizes the shaping process of the workpiece by pressing the forming part 11 into the deformation groove 7, thereby ensuring that the workpiece can be transformed into a finished product.

[0028] Therefore, the device is provided with a plurality of positioning holes 12 penetrating vertically on the pressure plate 6 in the circumferential direction, and a vertical axial positioning rod 2 is inserted into each positioning hole 12. By fixedly connecting the lower end surface of the positioning rod 2 to the support plate 1, the movement trajectory of the pressure plate 6 is constrained and guaranteed, thereby ensuring smooth progress of the stamping process.

[0029] At the same time, since the pressure plate 6 cooperates with the forming part 11 to shape the workpiece through up and down linear motion, and the pressure plate 6 has the power to move downward through the corresponding stamping equipment, the device is provided with a compression spring Ⅰ3 on the outside of each positioning rod 2, and the lower end of the compression spring Ⅰ3 is fixedly connected to the support plate 1. Therefore, when the forming part 11 finishes shaping the workpiece, the compression spring Ⅰ3 can release the elastic potential energy to reset the pressure plate 6, which can facilitate the user to remove the finished workpiece and put in the workpiece.

[0030] Specifically, in order to realize automatic positioning of the workpiece to be processed, the device is provided with a plurality of limit plates 9 in the circumferential direction of the lower end of the pressure plate 6 to constrain the projection of the limit plate 9 on the horizontal plane to coincide with the projection of the receiving plate 5 on the horizontal plane. At the same time, the height of the lower end surface of the limit plate 9 is less than the height of the lower end surface of the molded part 11. In this way, during the downward movement of the pressure plate 6, the multiple limit rods arranged circumferentially can be used to synchronously constrain the workpiece to be processed, thereby ensuring that the center axis of the workpiece to be processed coincides with the center axis of the molded part 11.

[0031] A sliding groove 8 is provided on the receiving plate 5 for the limiting plate 9 so as to avoid travel conflict between the limiting plate 9 and the receiving plate 5 .

[0032] Furthermore, in order to ensure that the limit plate 9 can push the workpiece to be processed to a suitable position, the device constrains the limit plate 9 to be a two-section structure. The lower end of the limit plate 9 is a driving section 902 with a triangular structure in the longitudinal section, and the height of the upper end surface of the driving section 902 is less than the height of the lower end surface of the molded part 11. This can achieve the position adjustment of the workpiece to be processed before the molded part 11 contacts the workpiece to be processed.

[0033] The upper end of the driving section 902 is a limiting section 901 with a rectangular structure in longitudinal section. The limiting section 901 can be used to fully limit the workpiece during the process of the molded part 11 applying pressure to the workpiece, ensuring that the workpiece will not move due to stress deformation.

[0034] Furthermore, when the compression spring Ⅰ3 of the device is not affected by external force, the height of the lower end surface of the driving section 902 is greater than the height of the upper end surface of the receiving plate 5. At this time, the operator can more conveniently place the workpiece to be processed above the receiving plate 5. At this time, the limit plate 9 is not in the same horizontal plane as the workpiece to be processed, thereby avoiding travel conflict.

[0035] Specifically, the device has a plurality of mounting plates 10 with an inverted L-shaped longitudinal section detachably connected to the lower end of the pressure plate 6, and the limiting plate 9 is fixed by the mounting plates 10 to ensure that the limiting plate 9 can move synchronously during the downward movement of the pressure plate 6.

[0036] Furthermore, an inner rod 15 is fixedly connected to one side of the limiting plate 9 close to the corresponding mounting plate 10 , an outer tube 13 is sleeved on the outer side of the inner rod 15 , and the outer tube 13 is fixedly connected to the corresponding mounting plate 10 .

[0037] A compression spring II 14 is sleeved on the outside of each inner rod 15, and the two axial ends of the compression spring II 14 are respectively abutted against the outer tube 13 and the mounting plate 10. At this time, in cooperation with the driving section 902 on the limit plate 9, the device can be adapted to workpieces of different sizes to be processed. In practice, the pressure plate 6 falls, and the driving section 902 abuts against the side wall of the workpiece to be processed. The reaction force generated by the elastic potential energy accumulated by the compression spring II 14 can further push the workpiece to be processed to a suitable position.

[0038] It should be emphasized that in the present device, the pressure plate 6 is detachably connected to the positioning plate, and the pressure plate 6 is detachably connected to the mounting plate 10. Therefore, the external structural features of the molded part 11 can be flexibly adjusted according to needs during use of the present device, and the compatibility range of the present device can be increased by cooperating with the compression spring II 14.

[0039] Specifically, the device realizes the connection process between the receiving plate 5 and the support plate 1 through the support member 4. In order to realize the detachable receiving plate 5 and facilitate the replacement of the receiving plate 5 so that the deformation groove 7 can be adapted to the molded part 11, the device is provided with an upper and lower axial screw 18 inside each support member 4.

[0040] The device has a screw 18 threadedly connected to the lower end of each internal threaded hole 16. The screw 18 is fixedly connected to the support plate 1 so that the support member 4 is also detachably connected to the support plate 1. This allows the device to flexibly select a support member 4 of a suitable height according to actual needs, ensuring that the support member 4 is adapted in depth to the deformation groove 7.

[0041] In this device, a bolt 19 is screwed on the upper end of each internal threaded hole 16. By opening a mounting hole on the receiving plate 5 and inserting the restraining bolt 19 into the mounting hole, a detachable connection between the receiving plate 5 and the support member 4 can be achieved.

[0042] Furthermore, the device is also provided with a matching hole 17 at the upper end of each support member 4, and the diameter of the matching hole 17 is constrained to be larger than the diameter of the internal threaded hole 16, and the matching hole 17 is projected as an inverted cone on the vertical plane, which can more conveniently achieve the purpose of matching the bolt 19 with the internal threaded hole 16, avoiding interference from the receiving plate 5 and causing inconvenience to the operator in installation.

[0043] In actual use, the utility model:

[0044] First, the operator selects a suitable receiving plate 5 and a molded part 11 according to the expected shape of the finished product;

[0045] Then, according to the structural characteristics of the deformation groove 7 on the receiving plate 5, a support member 4 of a suitable height is selected to ensure that the support member 4 is screwed with the corresponding screw rod 18;

[0046] Afterwards, the bolt 19 is passed through the mounting hole to ensure that the bolt 19 can be immersed in the internal threaded hole 16 and cooperate with the support member 4. At this time, the relative position of the receiving plate 5 cannot change;

[0047] Finally, the mounting plate 10 is installed in place, the positioning rod 2 is inserted into the corresponding positioning hole 12, and the device begins to be used normally.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
