[0002] Compression molding refers to a molding method that uses a single mold (single male mold or single female mold) or a pair of molds to make various plastic plates (sheets) with the help of external mechanical pressure or deadweight. The molds used in compression molding can be divided into male molds and female molds. The male mold refers to the shape of the mold is convex, and the female mold refers to the shape of the mold is concave.

[0003] The applicant obtained the following prior art through searching. Specifically, the patent with publication number CN219380947U discloses a molded pallet molding device, including a bottom plate, support rods are fixedly installed at the four corners of the upper surface of the bottom plate, a top plate is fixedly installed at the top of the support rods, a first hydraulic cylinder is fixedly installed on the top plate, a movable plate is fixedly installed at the end of the piston rod of the first hydraulic cylinder, a patterned plate is detachably installed at the lower end of the movable plate, a lower mold is fixedly installed on the upper surface of the bottom plate, a connecting frame is fixedly installed at the bottom end of the bottom plate, and a lifting mechanism is arranged in the connecting frame. When the molded pallet molding device is in use, the lifting mechanism is started after the molded pallet is molded, and the molded pallet is lifted by the lifting mechanism, and then the second hydraulic cylinder is started, and the molded pallet is pushed out by the ejection plate, thereby avoiding direct contact between manual labor and the newly molded molded pallet, and solving the problem in the prior art that the molded pallet has a high temperature after being molded in the molding device, and manual removal of the molded pallet is prone to burns.

[0004] It can be seen from the above patent that although the molded pallet molding device can directly push out the molded pallet through the ejector plate, solving the problem of easy burns when manually removing the molded pallet, in actual use, when the finished pallet needs to be taken out, the staff needs to turn the handwheel to drive the double-rotation screw to rotate so that the ejector rod can eject the pallet from the mold.

[0027] Embodiment 1:

[0028] The utility model provides a demoulding mechanism 100 for compression molding equipment.

[0029] In one embodiment of the utility model, a demolding mechanism 100 for a compression molding device is arranged on a base plate 1 of the compression molding device to demold the molded part. A through hole 2 is opened on the base plate 1. The compression molding device includes a mounting plate 3 for mounting a female mold, two supporting blocks 15 for placing blanks, a movable seat 16, a hydraulic cylinder 17 and a plurality of columns 18, including a mounting frame 4, a lifting rod 5 and a driving assembly. The mounting frame 4 is arranged on the bottom surface of the base plate 1, and a mounting sleeve 6 for detachably connecting to the base plate 1 is arranged at a position corresponding to the through hole 2 on the mounting frame 4. The lifting rod 5 is sleeved in the mounting sleeve 6 and slidingly contacts with the mounting sleeve 6, and the mounting sleeve 6 is connected to the through hole 2, so that one end of the lifting rod 5 can extend from the mounting sleeve 6 and pass through the through hole 2 to be connected to the mounting plate 3, and the driving assembly includes a pedal 12 that is transmission-connected to the lifting rod 5.

[0030] It should be noted that the compression molding device described in this embodiment is the compression molding device disclosed in the patent of the applicant with publication number CN220741899U, and the compression molding device is composed of a base plate 1, a mounting plate 3, two supporting blocks 15 for placing blanks, a movable seat 16, a hydraulic cylinder 17 and a plurality of columns 18, wherein the plurality of columns 18 are vertically arranged at the four corners of the base plate 1, the hydraulic cylinder 17 is arranged at the top of the plurality of columns 18, the movable seat 16 is slidably mounted on the plurality of columns 18 in the up and down directions, and the piston rod of the hydraulic cylinder 17 is detachably connected to the movable seat 16, so that the movable seat 16 can be relatively moved under the drive of the hydraulic cylinder 17. As the plurality of uprights 18 move up and down, a male mold is detachably mounted on a side of the movable seat 16 away from the hydraulic cylinder 17, thereby enabling the male mold to move up and down synchronously with the movable seat 16 under the action of the hydraulic cylinder 17; at the same time, since the two supporting blocks 15 are respectively arranged on both sides of the mounting plate 3 and are used to place the blank, and the mounting plate 3 is used to install the female mold, when the blank needs to be molded, the operator places the two side edges of the blank on the two supporting blocks 15 accordingly. At this time, the movable seat 16 moves downward under the drive of the hydraulic cylinder 17, and the male mold on the movable seat 16 moves downward synchronously and engages with the female mold on the mounting plate 3 to perform mold molding on the blank. It can be understood that when it is necessary to demold the molded part, the hydraulic cylinder 17 drives the movable seat 16 to move upward so that the male mold is separated from the molded part, and the female mold is also separated from the molded part under the action of the utility model. At this time, the excess blank connected to the molded part is placed on the support block 15, so that the molded part is placed on the two support blocks 15 as a whole, thereby completing the demolding operation of the molded product. It is worth noting that in the actual processing process, the two support blocks 15 can be provided with a limiting mechanism such as a pressure block according to the actual processing requirements, so as to prevent the molded part from adhering to the mold surface during the demolding process of the male mold or the female mold, resulting in demolding failure.

[0031] In the demoulding mechanism 100 for a compression molding device of the present invention, specifically, as Figures 1 to 3 As shown, by arranging the utility model on the bottom plate 1 of the compression molding equipment, since a through hole 2 is opened on the bottom plate 1, and the compression molding equipment has a mounting plate 3 on which a female mold is mounted, the upper end of the lifting rod 5 is connected to the mounting plate 3, and the lifting rod 5 is also connected to the pedal 12 in the driving assembly. When it is necessary to detach the molded part from the female mold, the staff can directly step on the pedal 12, so that the lifting rod 5 moves downward and synchronously drives the female mold on the mounting plate 3 to move downward, thereby detaching the molded part from the female mold. At this time, the male mold is also detached from the molded part under the action of the hydraulic cylinder 17, and the excess blanks on both sides of the molded part are placed on the supporting block 15, thereby completing the demolding operation of the molded part.

[0032] Furthermore, by setting the mounting sleeve 6 on the bottom surface of the base plate 1, and the lifting rod 5 is sleeved in the mounting sleeve 6 and slidingly contacted with the mounting sleeve 6, the stability of the lifting rod 5 moving up and down can be ensured. The mounting sleeve 6 guides the lifting rod 5, and the structural design is simple and reasonable.

[0033] It can be understood that since the mounting sleeve 6 is detachably mounted on the base plate 1 of the compression molding equipment, its detachable connection method can be a threaded connection, which facilitates the disassembly and maintenance of the mounting sleeve 6 and the mounting frame 4, and also enables the utility model to be installed on different compression molding equipment, which is flexible and convenient to use.

[0034] Compared with the prior art, the demoulding mechanism 100 for compression molding equipment of the utility model can directly step on the pedal 12 to separate the female mold from the molded part, and the male mold is separated from the molded part under the action of the hydraulic cylinder 17, and the molded part after demoulding is placed on two supporting blocks 15, so that the staff does not need to spend a lot of time to perform other demoulding operations such as screwing the hand wheel, which not only shortens the demoulding and production processing time, but also improves work efficiency, and also reduces the labor intensity of the staff. It is easy to operate, simple, and reliable to use. In addition, since the mounting sleeve 6 can be detachably mounted on the bottom plate 1 of the compression molding equipment, it is convenient to disassemble and repair the mounting sleeve 6 and the mounting frame 4, and it also makes the utility model applicable to different compression molding equipment, and it is more flexible and convenient to use.

[0035] In one embodiment, the driving assembly also includes an elastic member 7, a connecting seat 8, a driving rod 9 and a connecting rod 10. One end of the lifting rod 5 away from the mounting plate 3 extends out of the mounting sleeve 6 and is connected to the connecting seat 8. The elastic member 7 is arranged between the connecting seat 8 and the mounting frame 4. The driving rod 9 is rotatably mounted on the mounting frame 4 through the connecting rod 10, and the two ends of the connecting rod 10 are respectively hinged to the connecting seat 8 and the driving rod 9, so that the driving rod 9 can drive the lifting rod 5 to move up and down relative to the mounting frame 4.

[0036] Specifically, Figures 1 to 3 As shown, the lower end of the lifting rod 5 extends out of the mounting sleeve 6 and is connected to the connecting seat 8, and the elastic member 7 is arranged between the connecting seat 8 and the mounting frame 4. When the staff does not step on the pedal 12, the upper end of the lifting rod 5 always maintains the state of extending to the through hole 2 under the elastic restoring force of the elastic member 7. Since the upper end of the lifting rod 5 is connected to the mounting plate 3, it is convenient to install and replace the mold on the mounting plate 3. When the staff steps on the pedal 12, since the driving rod 9 is rotatably mounted on the mounting frame 4, the driving rod 9 rotates downward and synchronously drives the connecting rod 10 to rotate. The connecting seat 8 moves downward under the drive of the connecting rod 10. At the same time, the connecting seat 8 stretches the elastic member 7 and causes the lifting rod 5 to move downward, thereby driving the female mold on the mounting plate 3 to move downward, thereby completing the demoulding operation of the molded product and the female mold. The structural design is ingenious and reasonable.

[0037] It is worth noting that when the compression molding equipment performs compression molding, the bottom plate 1 is also connected to a limit pad for supporting the mounting plate 3 through components such as a cylinder, so that the limit pad can ensure the stability during the compression molding process. When demolding is required, the cylinder drives the limit pad to withdraw the limit support for the mounting plate 3, thereby providing the mounting plate 3 with a moving space to move downward, so that the lifting rod 5 can drive the mounting plate 3 and the female mold on the mounting plate 3 to move downward and achieve separation from the molded part.

[0038] In one embodiment, a rotating seat 11 is rotatably mounted on the mounting frame 4, and one end of the driving rod 9 is detachably mounted on the rotating seat 11 through a locking assembly. Figure 3 As shown, the rear end of the driving rod 9 is detachably mounted on the rotating seat 11 through a locking assembly, so that the driving rod 9 can be easily disassembled, assembled and replaced.

[0039] In one embodiment, specifically, Figure 3 As shown, the locking assembly includes a stud and a butterfly nut 13. One end of the stud passes through the rotating seat 11 and the driving rod 9 and is threadedly connected to the butterfly nut 13, so that the staff can adjust the initial angle of the driving rod 9 relative to the rotating seat 11 by screwing the butterfly nut 13, and then adjust the initial height of the pedal 12, so that different staff can step on the pedal 12 comfortably and conveniently, thereby optimizing the user experience.

[0040] In one embodiment, if Figure 3 As shown, the middle section of the driving rod 9 is a downwardly concave bending section. It can be understood that according to the lever principle, by making the middle section of the driving rod 9 into a downwardly concave bending section, the staff can save more effort when stepping on the pedal 12, thereby further reducing the labor intensity of the staff and facilitating use.

[0041] In one embodiment, if Figure 3As shown, connecting plates 14 are provided on both sides of the bending section, and one end of the connecting rod 10 is hinged between the two connecting plates 14 through a rotating shaft. Specifically, since the bending section is located in the middle of the driving rod 9, when the staff steps on the pedal 12, the driving rod 9 can better drive the connecting rod 10 and the lifting rod 5 to move downward, and the force is more uniform and reasonable; at the same time, one end of the connecting rod 10 is hinged between the two connecting plates 14 through a rotating shaft, thereby improving the stability of the connecting rod 10 when rotating, and the structural design is simple and reasonable.

[0042] In one embodiment, if Figure 3 As shown, the elastic member 7 is a spring, which is sleeved on the lifting rod 5, and the two ends of the spring are respectively connected to the mounting frame 4 and the connecting seat 8. It can be understood that the spring has the characteristics of easy material acquisition, simple structure, and large elastic deformation force, so it is more conducive to driving the lifting rod 5 to move up and down.

[0043] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
