Description

Technical Field

[0001] This utility model relates to the field of air fryer production and processing, and in particular to a stamping mold for an air fryer duct plate. Background Technology

[0002] The air duct plate is a key structural component inside the air fryer, mainly used for heat dissipation and optimizing hot air circulation, thereby improving cooking efficiency and safety. The air duct plate is usually made of metal sheet and processed by stamping molds, which can efficiently and precisely form a complex air duct structure to meet the needs of efficient heat dissipation and hot air circulation in the air fryer.

[0003] The air duct plate can be processed using a stamping die. For example, the existing technology, Chinese Patent Publication No. "CN214349084U", provides a stamping die for an air fryer air duct plate, relating to the field of mechanical processing technology. It includes a base and a clamping device. Four symmetrically arranged fixing columns are fixedly connected to the upper surface of the base. A pressing block is sleeved and slidably connected to the end of each fixing column away from the base. The clamping device is located on the upper surface of the base and includes a slide rail. A fixing block is slidably connected to the inner wall of the slide rail, with the side of the fixing block away from the slide rail abutting against the base. Three symmetrically arranged limiting springs are fixedly connected to the inner wall of the slide rail, with the side of the limiting spring away from the slide rail fixedly connected to the fixing block. This invention solves the problem that in the use of existing stamping dies, the workpiece placed inside the die is prone to displacement, resulting in errors between the displaced workpieces, leading to low die yield and difficulty in recycling and reusing the stamped workpieces, increasing the production cost for manufacturers.

[0004] Among them, the air duct plate also needs to be perforated and slotted through the plug-in parts. For example, the existing technology Chinese patent announcement number "CN210475233U" discloses an anti-clogging material stamping die, including a press, an upper template, a limit sleeve, a positioning rod, a telescopic spring, a lower template, a storage chamber, a drop cavity, and an anti-clogging port. The press is assembled on the upper end face of the stamping shell, the upper template is installed on the lower side of the press, the positioning rod is installed on the left side of the upper end face of the fixed box, the limit sleeve is fitted on the upper side of the annular side of the positioning rod, the telescopic spring is installed on the annular side of the positioning rod, the lower template is installed on the lower side of the upper template, the anti-clogging port is opened in the middle of the lower template, the drop cavity is opened below the anti-clogging port, and the storage chamber is opened below the drop cavity.

[0005] In practice, the processing of air duct plates usually requires punching holes and slotting through stamping parts. The waste generated during punching and slotting is mostly cleaned by the guide plate. However, considering that the waste may become blocked between the guide plate due to friction and large amount of material feeding, it is not possible to clear the blockage of the waste, which will affect the efficiency of subsequent processing. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies that cannot clear clogged waste materials, and to propose a stamping mold for air fryer duct plates.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design an air fryer duct plate stamping die, including an upper die base and a lower die base. The side wall of the lower die base is connected to the internal waste groove to form a material discharge port. The lower die base is located inside the material discharge port and is provided with a guide plate by an elastic element.

[0009] The upper mold base has a detachable pressing structure connected to its side wall via an elastic structure. The pressing structure moves vertically relative to the lower mold base. The pressing structure, in conjunction with the elastic element, drives the guide plate to shake.

[0010] Furthermore, the lower mold base is fixedly connected to a support rod inside the material discharge port, one end of the guide plate is placed in the waste trough, and the bottom of one end of the guide plate is rotatably connected to the support rod;

[0011] The elastic element is a spring, and its two ends are connected to the side wall of the waste trough and the bottom of the guide plate, respectively.

[0012] Furthermore, the elastic structure includes a connector and an elastic body. The connector has a T-shaped structure and is fixedly connected to the side wall of the upper mold base. The elastic body has a cavity inside, and one side of the elastic body communicates with the cavity to form an opening groove.

[0013] Furthermore, a deformation groove is formed on the inner wall of the elastic body on the side away from the opening groove to form an elastic part, and at least one pair of protrusions are provided on the inner side of the elastic part, and the pair of protrusions and the opening groove form a cross structure.

[0014] The rod-shaped portion of the connector passes through the opening slot and is stopped between a pair of protrusions by abutting and sliding.

[0015] Furthermore, the pressing structure includes a connecting rod, the top of which is fixedly connected to the bottom of the elastic body, and a stop block is rotatably connected to the bottom of the connecting rod via a pin. A torsion spring is sleeved at the end of the pin, and both ends of the torsion spring are fixedly connected to the connecting rod and the stop block, respectively.

[0016] Furthermore, one end of the guide plate away from the elastic element is placed outside the lower mold base, and the other end of the guide plate is provided with a rod-shaped part on the side wall;

[0017] The abutment block moves downward and avoids contact with the rod-shaped part through the torsion spring, while the abutment block rises and slides against the bottom of the rod-shaped part.

[0018] The present invention provides a stamping die for an air fryer duct plate, which has the following advantages: A guide plate is provided in the waste groove of the lower die base. When the upper and lower die bases are closed during stamping, the pressing structure moves synchronously with the upper die base. The pressing structure, in conjunction with the elastic element, drives the guide plate to rotate half a revolution along the support rod. The guide plate, through the half-revolution and the swaying motion generated during resetting, discharges the waste material to prevent blockage. Furthermore, after prolonged use, the pressing structure can be disassembled from the upper die base via the elastic structure for easy assembly or replacement. The structure is simple and highly practical. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 An air fryer duct plate stamping die includes an upper die base 1 and a lower die base 2. The side wall of the lower die base 2 is connected to the internal waste groove 21 to form a discharge port 22. The lower die base 2 is located inside the discharge port 22 and is provided with a guide plate 4 through an elastic element 3.

[0027] Among them, a pressing structure 6 is detachably connected to the side wall of the upper mold base 1 through an elastic structure 5. The pressing structure 6 and the lower mold base 2 move relative to each other vertically. The pressing structure 6, in conjunction with the elastic element 3, drives the guide plate 4 to shake.

[0028] It should be added that the waste trough 21 is connected to the mold body discharge port at the top of the lower mold base 2. Then, the waste generated by the stamping of the upper mold base 1 through the air duct plate enters the waste trough 21, and the waste is discharged outward through the guide plate 4.

[0029] Among them, the guide plate 4 is tilted under the action of the elastic element 3, that is, the end of the guide plate 4 near the elastic element 3 is tilted upward to facilitate the discharge of waste material;

[0030] Furthermore, the top of the upper mold base 1 is usually connected to the drive unit, and the upper mold base 1 and the lower mold base 2 move relative to each other up and down, stamping the air duct plate by means of mold closing.

[0031] Furthermore, the lower mold base 2 is fixedly connected to the support rod 23 inside the material outlet 22, one end of the guide plate 4 is placed inside the waste trough 21, and the bottom of one end of the guide plate 4 is rotatably connected to the support rod 23;

[0032] The elastic element 3 is a spring, and its two ends are connected to the side wall of the waste trough 21 and the bottom of the guide plate 4, respectively.

[0033] Furthermore, the elastic structure 5 includes a connector 51 and an elastic body 52. ​​The connector 51 has a T-shaped structure and is fixedly connected to the side wall of the upper mold base 1. The elastic body 52 has a cavity inside, and one side of the elastic body 52 communicates with the cavity to form an opening groove 521.

[0034] More specifically, the elastic body 52 has a deformation groove formed on the inner wall of the side away from the opening groove 521 to form an elastic part 53. The elastic part 53 has at least one pair of protrusions 54 on its inner side, and the pair of protrusions 54 and the opening groove 521 form a cross structure.

[0035] The rod-shaped portion of the connector 51 passes through the opening slot 521 and is stopped between the pair of protrusions 54 by abutting and sliding.

[0036] In this embodiment, the elastomer 52 is preferably made of a material with deformation capability such as rubber or plastic. Specifically, the elastomer 52 places the connector 51 into the cavity through the opening groove 521. Then, the elastomer 52 and the connecting rod 61 rotate half a circle. At the same time, the rod-shaped part of the connector 51 is stopped between a pair of protrusions 54 by abutting and sliding, thereby fixing the elastomer 52 and the connecting rod 61.

[0037] Of course, a pair of guide plates 4 are provided on the side of the upper and lower mold base 2 in the attached figure. The pair of guide plates 4 are spaced apart, and this gap does not affect the rotation of the connecting rod 61.

[0038] In general, the pressing structure 6 includes a connecting rod 61, the top of which is fixedly connected to the bottom of the elastic body 52, and the bottom of the connecting rod 61 is rotatably connected to a stop block 62 via a pin. A torsion spring 63 is sleeved on the end of the pin, and the two ends of the torsion spring 63 are fixedly connected to the connecting rod 61 and the stop block 62, respectively.

[0039] Finally, the end of the guide plate 4 away from the elastic member 3 is placed outside the lower mold base 2, and the other end of the guide plate 4 is provided with a rod-shaped part 41 on the side wall;

[0040] The abutment block 62 moves downward and abuts against the rod-shaped part 41 through the torsion spring 63, while the abutment block 62 rises and slides against the bottom of the rod-shaped part 41.

[0041] In this embodiment, when the upper mold base 1 and the lower mold base 2 are closed, the connecting rod 61 moves up and down with the upper mold base 1. In the initial state, the connecting rod 61 moves downward so that the abutment block 62 abuts against the connecting rod 61. At this time, the abutment block 62 rotates slightly under the action of the torsion spring 63 to avoid the rod-shaped part 41.

[0042] When the upper mold base 1 and the lower mold base 2 are separated, the abutment block 62 contacts the bottom of the connecting rod 61 because the torsion spring 63 can only twist in one direction. Then, the lifting force generated by the contact drives the end of the guide plate 4 away from the elastic member 3 to rise.

[0043] It should be noted that because the guide plate 4 rotates half a circle along the support rod 23, after the guide plate 4 rotates to a certain angle, the rod-shaped part 41 and the abutment block 62 separate due to the loss of contact area. The guide plate 4 is reset under the action of the elastic element 3 and shakes to feed the waste material.

[0044] Working method: During operation, the elastic body 52 places the connector 51 into the cavity through the opening groove 521. Then, the elastic body 52 and the connecting rod 61 rotate half a circle. At the same time, the rod-shaped part of the connector 51 is stopped between a pair of protrusions 54 by the sliding stop, thereby fixing the elastic body 52 and the connecting rod 61.

[0045] When the upper mold base 1 is driven by the drive unit to close with the lower mold base 2, the connecting rod 61 moves up and down with the upper mold base 1. The connecting rod 61 moves downward so that the abutment block 62 abuts against the connecting rod 61. At this time, the abutment block 62 rotates slightly under the action of the torsion spring 63 to avoid the rod-shaped part 41. When the upper mold base 1 and the lower mold base 2 separate, the connecting rod 61 drives the end of the guide plate 4 away from the elastic member 3 to rise through the lifting force generated by the abutment.

[0046] After the guide plate 4 rotates to a certain angle, the rod-shaped part 41 separates from the stop block 62, and the guide plate 4 resets under the action of the elastic element 3 and shakes to feed the waste material.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
