Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, and in particular to a packaging box pressing mold for packaging box processing. Background Technology

[0002] During the packaging box processing, the packaging box needs to be stamped and formed, which requires the use of a pressing mold. After the pressing mold stamps and forms the packaging box, an ejection mechanism is usually required to eject the pressed packaging from the bottom mold during demolding.

[0003] In existing packaging box pressing molds, the ejection mechanism typically employs either manual or automatic methods to eject the packaging box. Manual ejection mechanisms usually require an operator to manually push the ejector plate upwards after demolding, thus ejecting the pressed packaging box from the bottom mold. This method increases the labor intensity of the workers and affects work efficiency. Automatic ejection mechanisms typically use a separate hydraulic rod to move the ejector plate upwards, ejecting the pressed packaging box from the bottom mold. This method requires a separate hydraulic rod, increasing costs and the difficulty of subsequent maintenance, thus affecting practicality. Therefore, this paper proposes a packaging box pressing mold for packaging box processing to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the above-mentioned background art, and to propose a packaging box pressing mold for packaging box processing.

[0005] The technical problem to be solved by this utility model is to provide a packaging box pressing mold for packaging box processing, which solves the problem that the ejection mechanism of the packaging box pressing mold in the prior art usually adopts two methods, manual or automatic, to achieve the ejection of the packaging box, which has the problem of inconvenience in operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging box pressing mold for packaging box processing, comprising a base box, a bottom mold, a support, a hydraulic rod, a lifting plate, and a top mold. The bottom mold is fixedly installed at the center of the upper surface of the base box, the support is fixedly installed on the right side of the upper surface of the base box, the hydraulic rod is fixedly installed at the center of the top of the support, the lifting plate is fixedly installed at the output end of the hydraulic rod, the top mold is fixedly installed at the center of the bottom of the lifting plate, an ejector plate is provided at the bottom inner side of the bottom mold, and a linkage component is installed on the lifting plate to drive the ejector plate upward during demolding and eject the product inside the bottom mold.

[0007] Preferably, the top mold is located directly above the bottom mold, and when the hydraulic rod is extended to its maximum length, the top mold is embedded in the bottom mold.

[0008] Preferably, guide sleeves are fixedly provided on both the left and right sides of the lifting plate, and the guide sleeves are sleeved on the left and right sides of the bracket.

[0009] Preferably, the linkage assembly includes a collar fixed to the center of the outer surface of the guide sleeve and a guide rod passing through the collar. A horizontal plate is fixedly provided at the bottom of the two guide rods. Multiple connecting rods are fixedly provided at the center of the upper surface of the horizontal plate. A fixing plate is fixedly provided on the upper surface of the two guide rods. The top of the connecting rod is fixedly provided on the bottom surface of the ejector plate.

[0010] Preferably, the left and right sides of the bottom box are provided with through grooves that match the horizontal plate, and the horizontal plate can slide up and down along the through grooves.

[0011] Preferably, the bottom of the bottom mold has an embedding groove that matches the ejector plate, and the bottom of the embedding groove has multiple through holes that match the connecting rods. The through holes extend through the upper surface of the bottom box, and the connecting rods extend through the through holes.

[0012] Preferably, the diameter of the fixing disc is larger than the diameter of the central through hole of the collar.

[0013] Preferably, when the bottom surface of the horizontal plate is attached to the inner bottom of the bottom box, the top plate is completely embedded in the embedding groove.

[0014] Preferably, when the bottom surface of the horizontal plate is attached to the inner bottom of the bottom box, the difference between the horizontal height of the fixing plate and the horizontal height of the upper surface of the bottom mold is greater than the thickness of the bottom mold.

[0015] Preferably, when the top of the lifting plate is attached to the upper inner side of the bracket, the horizontal height of the upper surface of the ejector plate is equal to the horizontal height of the upper surface of the bottom mold.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] 1. In the process of stamping and forming the packaging box, the hydraulic rod extends and retracts to move the lifting plate downwards until its horizontal height is lower than that of the fixed plate. At this time, under the action of the gravity of the ejector plate, the ejector plate is embedded in the embedding groove of the bottom mold. Then, the cardboard of the packaging box to be stamped and formed is placed into the bottom mold. The hydraulic rod drives the lifting plate and the top mold to move downwards, and the top mold is embedded in the bottom mold to realize the pressing and forming of the packaging box.

[0018] 2. This utility model, by incorporating a linkage component, allows for demolding. During demolding, a hydraulic rod drives a lifting plate upwards, which in turn moves the top mold upwards until it detaches from the bottom mold, achieving demolding. The hydraulic rod then drives the lifting plate upwards until a collar on the lifting plate contacts a fixed plate. This collar moves the fixed plate and guide rod upwards, which in turn moves the horizontal plate and connecting rod upwards. The connecting rod then moves the ejector plate upwards until the lifting plate rests against the inner top of the support. At this point, the upper surface of the ejector plate is level with the upper surface of the bottom mold, automatically ejecting the pressed packaging box from the bottom mold. This eliminates the need for an additional drive component to eject the pressed packaging box, increasing work efficiency and reducing maintenance costs. Attached Figure Description

[0027] Example:

[0028] like Figures 1-5As shown, an embodiment of this utility model provides a packaging box pressing mold for packaging box processing, including a base box 1, a bottom mold 2, a support 3, a hydraulic rod 4, a lifting plate 5, and a top mold 6. The bottom mold 2 is fixedly installed in the center of the upper surface of the base box 1. The support 3 is fixedly installed on the right side of the upper surface of the base box 1. The hydraulic rod 4 is fixedly installed in the center of the top of the support 3. The lifting plate 5 is fixedly installed at the output end of the hydraulic rod 4. The top mold 6 is fixedly installed in the center of the bottom of the lifting plate 5. An ejector plate 7 is provided on the bottom inner side of the bottom mold 2. A linkage component is installed on the lifting plate 5 to drive the ejector plate 7 to move upward and eject the product in the bottom mold 2 when demolding.

[0029] In this embodiment, the top mold 6 is located directly above the bottom mold 2, and when the hydraulic rod 4 extends to its maximum length, the top mold 6 is embedded in the bottom mold 2, achieving the effect of packaging and pressing.

[0030] In this embodiment, guide sleeves 501 are fixedly provided on both the left and right sides of the lifting plate 5. The guide sleeves 501 are sleeved on the left and right sides of the bracket 3 to ensure the stability of the lifting plate 5 when it is raised or lowered.

[0031] In this embodiment, the linkage component includes a collar 502 fixed to the center of the outer surface of the guide sleeve 501 and a guide rod 8 passing through the collar 502. A horizontal plate 801 is fixedly provided at the bottom of the two guide rods 8. Multiple connecting rods 802 are fixedly provided at the center of the upper surface of the horizontal plate 801. A fixing plate 803 is fixedly provided on the upper surface of the two guide rods 8. The top of the connecting rods 802 is fixedly provided on the bottom surface of the ejector plate 7.

[0032] When stamping the packaging box, the hydraulic rod 4 extends and retracts, causing the lifting plate 5 to move downwards until its horizontal height is lower than that of the fixed plate 803. At this time, under the action of gravity of the ejector plate 7, the ejector plate 7 is embedded in the embedding groove 201 of the bottom mold 2. Then, the cardboard of the packaging box to be stamped is placed into the bottom mold 2. The hydraulic rod 4 drives the lifting plate 5 and the top mold 6 to move downwards. The top mold 6 is embedded in the bottom mold 2, thereby realizing the pressing and forming of the packaging box.

[0033] By incorporating a linkage component, during demolding, the hydraulic rod 4 drives the lifting plate 5 upward, which in turn drives the top mold 6 upward until the top mold 6 is ejected from the bottom mold 2, achieving the demolding effect. The hydraulic rod 4 then drives the lifting plate 5 to continue moving upward until the collar 502 on the lifting plate 5 contacts the fixed plate 803. The collar 502 then drives the fixed plate 803 and guide rod 8 upward, which in turn drives the horizontal plate 801 and connecting rod 802 upward. The connecting rod 802 then drives the ejector plate 7 upward until the lifting plate 5 is attached to the inner top of the bracket 3. At this point, the horizontal height of the upper surface of the ejector plate 7 is equal to the horizontal height of the upper surface of the bottom mold 2, achieving the effect of automatically ejecting the pressed packaging box from the bottom mold 2. This eliminates the need for an additional drive component to drive the ejector plate 7 to eject the pressed packaging box, increasing work efficiency and reducing maintenance costs.

[0034] In this embodiment, the left and right sides of the base box 1 are provided with through grooves 101 that match the horizontal plate 801, and the horizontal plate 801 can slide up and down along the through grooves 101 to ensure the stability of the horizontal plate 801 when it is raised or lowered.

[0035] In this embodiment, the bottom of the bottom mold 2 is provided with an embedding groove 201 that matches the ejector plate 7. The bottom of the embedding groove 201 is provided with multiple through holes 202 that match the connecting rod 802. The through holes 202 penetrate the upper surface of the bottom box 1, and the connecting rod 802 passes through the through holes 202, which facilitates the connection between the connecting rod 802 and the ejector plate 7.

[0036] In this embodiment, the diameter of the fixed disk 803 is larger than the diameter of the central through hole of the collar 502.

[0037] In this embodiment, when the bottom surface of the horizontal plate 801 is attached to the inner bottom of the bottom box 1, the ejector plate 7 is completely embedded in the embedding groove 201.

[0038] In this embodiment, when the bottom surface of the horizontal plate 801 is attached to the inner bottom of the bottom box 1, the difference between the horizontal height of the fixed plate 803 and the horizontal height of the upper surface of the bottom mold 2 is greater than the thickness of the bottom mold 2. When the hydraulic cylinder drives the lifting plate 5 to move upward until the horizontal height of the collar 502 is equal to the bottom horizontal height of the fixed plate 803, there is a distance between the top mold 6 and the bottom mold 2, which makes it convenient to put the packaging cardboard to be pressed into the bottom mold 2 and also convenient to take out the ejected packaging cardboard.

[0039] In this embodiment, when the top of the lifting plate 5 is attached to the inner side of the bracket 3, the horizontal height of the upper surface of the ejector plate 7 is equal to the horizontal height of the upper surface of the bottom mold 2, which makes it convenient for the ejector plate 7 to eject the cardboard of the packaging box.

[0040] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
