Description

Technical Field

[0001] The utility model relates to the technical field of cake cup production molds, and specifically relates to a stamping mold for producing flanged cake paper cups. Background Technique

[0002] In order to facilitate the production of some small and cute cakes, cake cups are needed to hold the cake liquid. In some factories, paper cup cakes need to be produced in batches, so the demand for cake paper cups is relatively high.

[0003] Traditional cake paper cups generally have a corrugated cup wall shape. The production of cake cups by traditional cake cup forming machines is divided into two types. One is injection molding. However, due to the complex structure of the cup wall, demolding is very difficult and it is easy to cause defective products. The second is similar to ordinary paper cups, with a fan-shaped cup wall and a cup bottom glued together. The paper cake cups produced by this process not only have a cumbersome process, but also the seams are not beautiful enough and not firm enough.

[0004] However, precisely due to the complex structure of the cup wall of the cake cup, it can be made by stamping from only one circular piece of paper. Content of the Utility Model

[0005] This application provides a stamping mold for producing flanged cake paper cups, which quickly presses a circular piece of paper into a cup shape through the cooperation of mold A and mold B to solve the technical problem of rapid production and manufacturing under the large demand for cake cups.

[0006] A stamping mold for producing flanged cake paper cups provided by this application includes mold A for stamping and manufacturing semi-finished paper cups and mold B for secondary processing of semi-finished paper cups into flanged cake cups; mold A includes moving mold A, moving mold B and stationary mold B. A tooth mold groove A is arranged on moving mold A, and a tooth mold groove B is arranged on the outer ring of stationary mold B opposite to tooth mold groove A. A punch A is arranged in the inner ring of tooth mold groove A, and a forming groove is arranged in the inner ring of tooth mold groove B. The punch A and the forming groove form a cavity A of the cup body structure of the semi-finished paper cup; mold B includes moving mold C, flanging press mold and stationary mold D. Moving mold C and stationary mold D form a cavity B that matches the cup wall and cup bottom of the semi-finished paper cup. And a flanging groove A is also arranged on stationary mold D. The flanging groove A and the flanging groove B on the flanging press mold match to form a flanging cavity. The flanging cavity and cavity B form a mold inner cavity that matches the flanged cake cup.

[0007] As a further setting of the above solution, the cavity formed by tooth mold groove A and tooth mold groove B is connected to cavity A, and the cavity size of the connection cavity between the two is larger than the cup wall thickness of the semi-finished paper cup. A blanking groove is arranged at the bottom of stationary mold B relative to cavity A.

[0008] As a further setting of the above solution, folding edge pressing grooves are also arranged on stationary mold B and moving mold B.

[0009] As a further setting of the above solution, the hemming groove A provided on the hemming die and the hemming groove B provided on the stationary die D are both arranged as hemispherical inner grooves, which are used to guide the folded edge of the semi-finished paper cup to curl along the inner wall of the hemming cavity based on pressure when the molds are closed to form a hemmed cake cup.

[0010] One or more technical solutions provided in this application have at least the following technical effects or advantages: The production stamping die of the present utility model punches and forms a circular raw material sheet in two stages through die A, so that the middle part of the circular raw material sheet is punched into a cup bottom, and the outer ring part is extruded and folded to form a cup wall. The cake cup formed by die A has a uniform cup wall without any connection seams, and the whole cake cup is seamless, complete and beautiful. Then, based on die B, it is further processed to form a hemming structure, which not only facilitates the hemming for use, but also makes it more beautiful. Compared with the prior art, the cake cup produced by using the die of the present utility model has a structure with a thinner upper part and a thicker lower part, which is relatively durable, and can be folded and unfolded during use to restore it to the shape of a circular raw material sheet, so that the whole cake in the cup body can be taken out conveniently for users to eat, and the finished cake cup has uniform folding line patterns on the outside, which is beautiful and non-slip.

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0022] As Figure 1-8 shown, a stamping mold for producing a crimped cake paper cup of the present invention includes the following structures:

[0023] A mold A1 for stamping and manufacturing a semi-finished paper cup 8 and a mold B2 for secondary processing the semi-finished paper cup 8 into a crimped cake cup 9;

[0024] The mold A1 includes a moving mold A11, a moving mold B12, and a stationary mold B13. A tooth mold groove A111 is provided on the moving mold A11. A tooth mold groove B131 is provided on the outer ring of the stationary mold B13 opposite to the tooth mold groove A111. A punch A112 is provided in the inner ring of the tooth mold groove A111. A forming groove 132 is provided in the inner ring of the tooth mold groove B131. The punch A112 and the forming groove 132 form a mold cavity A14 for the cup body structure of the semi-finished paper cup 8.

[0025] The mold B2 includes a moving mold C21, a crimping mold 22, and a stationary mold D23. The moving mold C21 and the stationary mold D23 form a mold cavity B that matches the cup wall and the cup bottom of the semi-finished paper cup 8. A crimping groove A24 is further provided on the stationary mold D23. The crimping groove A24 and the crimping groove B25 on the crimping mold 22 match to form a crimping cavity 26. The crimping cavity 26 and the mold cavity B form a mold content cavity that matches the crimped cake cup 9.

[0026] As a further setting of the above solution, the cavity formed by the tooth die groove A111 and the tooth die groove B131 communicates with the cavity A14 of the die cavity, and the cavity size of the connecting cavity 141 between the two is larger than the wall thickness of the semi-finished paper cup 8. A blanking groove 142 is arranged at the bottom of the static die B13 relative to the cavity A14.

[0027] As a further setting of the above solution, hemming pressure grooves 18 are also arranged on the static die B13 and the moving die B12.

[0028] As a further setting of the above solution, the hemming groove A24 arranged on the curling die 22 and the hemming groove B25 arranged on the static die D23 are both arranged as hemispherical inner grooves, which are used to guide the hemming of the semi-finished paper cup 8 along the inner wall of the curling cavity 26 to form a curled-edge cake cup 9 when the die is closed.

[0029] In this embodiment Figure 1-8 A stamping die for producing a curled-edge cake paper cup as shown, such as Figure 1-2 shown, includes a die A1 for stamping and manufacturing the semi-finished paper cup 8 and a die B2 for secondary processing the semi-finished paper cup 8 into a curled-edge cake cup 9. By using the production stamping die provided in this embodiment, a raw paper sheet in a circular shape can be processed step by step through the die A1 and the die B2 to form a curled-edge cake cup 9 structure with a curled-edge structure at the end of the cup wall and the cup wall gradually thinning upward from the edge of the bottom sheet. It should be noted that for the cake cup produced and manufactured in this embodiment, the cup wall near the bottom of the cup is formed by the overlap of the raw materials in the die A1 based on the special structure of the die. Therefore, the thickness dimension of the cup wall raw material is larger and the compressive resistance, anti-permeability and other abilities are stronger as it is closer to the bottom of the cup;

[0030] As Figure 2-4 shown, the die A1 of this embodiment includes a moving die A11, a moving die B12 and a static die B13. A tooth die groove A111 is arranged on the moving die A11, and a tooth die groove B131 is arranged on the outer ring of the static die B13 relative to the tooth die groove A111. A punch A112 is arranged in the inner ring of the tooth die groove A111, and a forming groove 132 is arranged in the inner ring of the tooth die groove B131. The punch A112 and the forming groove 132 form a cavity A14 of the cup body structure of the semi-finished paper cup 8;

[0031] As a further setting of the above solution, the cavity formed by the tooth die groove A111 and the tooth die groove B131 communicates with the cavity A14 of the die cavity, and the cavity size of the connecting cavity 141 between the two is larger than the wall thickness of the semi-finished paper cup 8. Hemming pressure grooves 18 are also arranged on the static die B13 and the moving die B12.

[0032] In use, the operation of mold A1 is divided into several steps. First, the staff places the circular raw material sheet on the stationary mold B13. Driven by the equipment, the moving mold A11 first moves closer to the stationary mold B13 for mold closing to press the circular raw material sheet. At this time, the middle part of the circular raw material sheet remains flat, while the outer circle generates Z-shaped high-low dislocation-shaped creases under the action of the tooth mold grooves A111 and B131 of the moving mold A11 and the stationary mold B13. The tooth mold grooves A111 and B131 are inclined. After mold closing is completed, the moving mold B12 starts to move towards the stationary mold B13 for mold closing. During this process, the moving mold A11 remains stationary. During the mold closing process of the moving mold B12, the convex mold A112 at the front end of the moving mold B12 presses and is based on the concave cavity of the forming groove 132. Thus, the convex mold A112 at the front end of the moving film B12 continuously moves downward to cooperate with the forming groove 132. During this process, the circular raw material sheet with a flanged edge moves downward under its pressure and is based on the gap between the tooth mold grooves A111 and B131. Therefore, it will not generate immovable pressure on the circular raw material sheet (it can also be controlled to move slightly upward to leave a gap). The flange of the circular raw material sheet is extruded by the convex mold A112 along the gap between the inclined tooth mold grooves A111 and B131 and falls into the mold cavity A14 formed by the forming groove 132. The Z-shaped high-low dislocation-shaped creases form a folded cup wall under the mold closing force. The cup wall formed in this way has no connection seam with the cup bottom, and the formed cup wall is thick at the bottom and thin at the top. The outer surface also has oblique stripe patterns, which are not only beautiful. When used for cakes, through external force tearing, it can be unfolded again to form a circular paper sheet to carry the cake, facilitating users to eat the cake in the cup. When using this cake cup, there is no need to use a spoon to dig out the cake from the cup additionally, nor to tear the cake cup. No seams mean no need to use seam glue, which is more environmentally friendly and healthier;

[0033] Secondly, as Figure 5-7 shown, the mold B2 of this embodiment includes a moving mold C21, a curling press mold 22, and a stationary mold D23. The moving mold C21 and the stationary mold D23 form a mold cavity B that matches the cup wall and cup bottom of the paper cup semi-finished product 8. The stationary mold D23 is also provided with a curling groove A24. The curling groove A24 and the curling groove B25 on the curling press mold 22 match to form a curling cavity 26. The curling cavity 26 and the mold cavity B form a mold content cavity that matches the curled cake cup 9.

[0034] As a further setting of the above solution, the curling groove A24 provided on the curling press mold 22 and the curling groove B25 provided on the stationary mold D23 are both provided as hemispherical inner grooves, which are used to guide the flange of the paper cup semi-finished product 8 to curl along the inner wall of the curling cavity 26 to form a curled cake cup 9 when the mold is closed.

[0035] As Figure 5-7When the mold B2 of the present embodiment shown is in use, it adopts a multiple clamping action with the mold A1. First, the semi-finished paper cup 8 demolded from the mold A1 is placed into the inner cavity of the stationary mold D23. Subsequently, the equipment is started, and the moving mold C21 moves first to perform clamping, secondarily pressing the bottom and the wall of the semi-finished paper cup 8 to enhance the strength. Then, the curling die 22 moves to perform clamping. The curling groove A24 provided on the curling die 22 and the curling groove B25 provided on the stationary mold D23 form a curling cavity 26 with a notched annular structure. Based on the arc-shaped curved surface of the inner wall of the curling cavity 26, during the clamping process, the folded edge that has been extruded and formed once by the mold A1 abuts against the arc-shaped curved surface, and then, driven by the subsequent clamping pressure, it is wound downward and inward along the arc-shaped curved surface of the inner wall of the curling cavity 26 to form an arc shape, as Figure 7 shown. Finally, the curled cake cup 9 after curling is demolded to obtain the finished cake cup.

[0036] It should be noted that for the convenience of demolding the semi-finished paper cup 8 and the curled cake cup 9, the stationary mold B13 and the stationary mold D23 of the present embodiment are both provided with ejector grooves 142 at the bottom of the mold cavity A14.

[0037] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.

[0038] This specification and the drawings are only exemplary descriptions of the present application and are considered to cover any and all modifications, variations, combinations, or equivalents within the scope of the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the scope of the present application.
