Description

Technical Field

[0001] The present application relates to the field of packaging equipment, and in particular to a locking device for assisting in the disassembly of a vacuum enclosure of an upper mold frame. Background Art

[0002] The vacuum enclosure is an integral part of the entire vacuum mold frame structure. Its primary function is to create a sealed vacuum environment within the mold frame by sealing it on all sides. Removing the vacuum enclosure is a prerequisite for removing the mold box, making it a crucial step in the entire mold frame dismantling process. Currently, vacuum enclosure removal involves using a lifting mechanism to separate the upper and lower mold frames. Once separated, the vacuum enclosure automatically falls off the upper mold frame.

[0003] When removing the vacuum enclosure from the upper mold frame, the lower mold frame must be removed first. Only after the lower mold frame is separated can the vacuum enclosure be removed from the upper mold frame. However, once the lower mold frame is removed, the vacuum enclosure from the upper mold frame will fall with it, potentially hitting the mold box in the lower mold frame, causing damage and injury to the operator.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:

[0006] The locking device for assisting in disassembling the vacuum enclosure of the upper mold frame provided by the utility model comprises an upper mold frame and a locking mechanism;

[0007] The upper mold frame includes an upper mold plate and an upper vacuum enclosure, wherein the upper mold plate is located on the top of the upper vacuum enclosure; a limiting protrusion is provided at the bottom of the upper mold plate, and a first locking hole is provided on the upper surface of the limiting protrusion;

[0008] The locking mechanism includes a connecting rod, a stopper, a fixed block and a latch, wherein the fixed block is mounted on the upper vacuum enclosure; one end of the stopper is movably connected to the fixed block, and the other end is sleeved with the connecting rod; the connecting rod is slidably connected to the stopper, and one end is provided with a second locking hole;

[0009] The locking mechanism includes an initial state and a locking state. When the locking mechanism is in the initial state, the connecting rod is opposite to the upper vacuum enclosure; when the locking mechanism is in the locking state, the connecting rod is located above the limiting protrusion, and the pin passes through the second locking hole and the first locking hole in sequence.

[0010] Furthermore, the connecting rod is slidably engaged with the stop block.

[0011] Furthermore, a blocking piece is provided at one end of the connecting rod away from the second locking hole.

[0012] Furthermore, when the locking mechanism is in the locked state, the blocking piece abuts against the side wall of the block.

[0013] Furthermore, the stop block and the fixed block are rotatably connected via a rotating shaft, and the axis of the rotating shaft is parallel to the axis of the connecting rod.

[0014] Furthermore, a clamping protrusion is provided on the side wall of the stopper, and when the locking mechanism is in the locked state, the clamping protrusion is clamped with the limiting protrusion.

[0015] Furthermore, the limiting protrusion is provided with a groove, and the engaging protrusion is engaged with the groove.

[0016] Furthermore, the stop blocks and the fixing blocks are both provided in plurality, and the fixing blocks are spaced apart along the axial direction of the connecting rod. The stop blocks are movably connected to the fixing blocks in a one-to-one correspondence and are all sleeved on the connecting rod.

[0017] Furthermore, it also includes an upper base plate and an upper heat insulation plate, and the upper heat insulation plate is located between the upper base plate and the upper template.

[0018] Furthermore, it also includes a lower mold frame, the lower mold frame includes a lower vacuum enclosure, and the end of the upper vacuum enclosure facing away from the upper template is in contact with the lower vacuum enclosure.

[0019] Based on the above technical solutions, the technical effects that can be achieved by this utility model are analyzed as follows:

[0020] The locking device for assisting in the disassembly of the upper mold frame vacuum enclosure provided by the utility model includes an upper mold frame and a locking mechanism; the upper mold frame includes an upper template and an upper vacuum enclosure, and the upper template is located at the top of the upper vacuum enclosure; a limiting protrusion is provided at the bottom of the upper template, and a first locking hole is provided on the upper surface of the limiting protrusion; the locking mechanism includes a connecting rod, a stopper, a fixed block and a latch, and the fixed block is installed on the upper vacuum enclosure; one end of the stopper is movably connected to the fixed block, and the other end is sleeved with a connecting rod; a second locking hole is provided at one end of the connecting rod; the locking mechanism includes an initial state and a locking state, and when the locking mechanism is in the initial state, the connecting rod is opposite to the upper vacuum enclosure; when the locking mechanism is in the locking state, the connecting rod is located above the limiting protrusion, and the latch passes through the second locking hole and the first locking hole in sequence.

[0021] A limiting protrusion is provided at the bottom of the upper template, which is used to set the first locking hole. When the connecting rod of the locking mechanism is located above the limiting protrusion, the locking mechanism can be locked by passing the pin through the second locking hole and then inserting it into the first locking hole.

[0022] The locking mechanism's fixing block is used to secure the locking mechanism to the sidewall of the upper vacuum enclosure and is movably connected to the stopper, allowing the stopper to drive the connecting rod to switch positions. The second locking hole can be opposite the first locking hole, allowing the latch to pass through the second locking hole and then be inserted into the first locking hole, locking the locking mechanism.

[0023] The locking mechanism for assisting in the removal of the upper mold frame's vacuum enclosure works as follows: by adjusting the position of the connecting rod, the locking mechanism locks the upper vacuum enclosure, enabling the mold frame to be disassembled in stages. First, the upper vacuum enclosure is secured to the upper mold plate via the locking mechanism, thereby securing both the upper vacuum enclosure and the upper mold plate together within the upper mold frame. The lower mold frame is then removed, and finally, the locking mechanism is released, separating the upper vacuum enclosure from the upper mold plate. The upper vacuum enclosure is then removed from the upper mold frame using the connecting rod. This locking mechanism for assisting in the removal of the upper mold frame's vacuum enclosure allows the upper vacuum enclosure to remain secured within the upper mold frame even after the lower mold frame is removed, protecting the mold box in the lower mold frame while effectively preventing the risk of the upper vacuum enclosure automatically falling off and injuring the operator during the removal of the lower mold frame.

[0024] The locking device for assisting in the removal of the upper mold frame vacuum enclosure is used as follows: the locking mechanism is installed on the upper vacuum enclosure. Before removing the lower mold frame, the locking mechanism is switched to the locked state to connect the upper vacuum enclosure to the upper mold plate, thereby securing the upper vacuum enclosure in the upper mold frame. After the upper vacuum enclosure is locked, the lower mold frame is removed as a whole. After the lower mold frame is removed, the locking mechanism is switched to the initial state to release the lock between the upper vacuum enclosure and the upper mold plate. Finally, the operator can remove the upper vacuum enclosure from the upper mold frame using a handheld connecting rod. The locking mechanism effectively prevents the upper vacuum enclosure from falling directly from the upper mold frame during the removal of the lower mold frame, striking the mold box of the lower mold frame and injuring the operator.

[0039] See also Figures 1 to 6 The locking device for assisting in disassembling the upper mold frame vacuum enclosure provided by the embodiment of the present invention includes an upper mold frame 100 and a locking mechanism 200; the upper mold frame 100 includes an upper template 110 and an upper vacuum enclosure 120, the upper template 110 is located on the top of the upper vacuum enclosure 120; a limiting protrusion 111 is provided at the bottom of the upper template 110, and a first locking hole 112 is provided on the upper surface of the limiting protrusion 111; the locking mechanism 200 includes a connecting rod 210, a stopper 220, a fixing block 230 and a latch, and the fixing block 230 is arranged Installed on the upper vacuum enclosure 120; one end of the stop block 220 is movably connected to the fixed block 230, and the other end is sleeved with a connecting rod 210; one end of the connecting rod 210 is provided with a second locking hole 211; the locking mechanism 200 includes an initial state and a locking state. When the locking mechanism 200 is in the initial state, the connecting rod 210 is opposite to the upper vacuum enclosure 120; when the locking mechanism 200 is in the locking state, the connecting rod 210 is located above the limiting protrusion 111, and the pin passes through the second locking hole 211 and the first locking hole 112 in sequence.

[0040] Specifically, in this embodiment, the cross-section of the connecting rod 210 is circular; however, a square cross-section of the connecting rod 210 is also within the scope of protection of this embodiment of the utility model. Furthermore, the sidewall of the stopper protrusion 111 is recessed inward to form a first locking hole 112. The latch passes through the second locking hole 211 and the first locking hole 112 in sequence, with the head of the latch overlapping the connecting rod 210.

[0041] See also Figure 1 and Figure 2The bottom of the upper template 110 is provided with a limiting protrusion 111, which is used to set the first locking hole 112. When the connecting rod 210 of the locking mechanism 200 is located above the limiting protrusion 111, the locking mechanism 200 can be locked by passing the latch through the second locking hole 211 and then inserting it into the first locking hole 112. The fixing block 230 of the locking mechanism 200 is used to fix the locking mechanism 200 to the side wall of the upper vacuum enclosure 120, and is used to be movably connected with the stopper 220 so that the stopper 220 can drive the connecting rod 210 to switch positions. The second locking hole 211 of the connecting rod 210 can be opposite to the first locking hole 112, so that the latch passes through the second locking hole 211 and is inserted into the first locking hole 112, so that the locking mechanism 200 is locked.

[0042] The principle of the locking device for assisting in the removal of the upper mold frame vacuum enclosure is as follows: by adjusting the position of the connecting rod 210, the locking mechanism 200 is locked to the upper vacuum enclosure 120, thereby achieving step-by-step disassembly of the mold frame. First, the upper vacuum enclosure 120 is fixed to the upper mold plate 110 via the locking mechanism 200, thereby achieving the joint fixation of the upper vacuum enclosure 120 and the upper mold plate 110 in the upper mold frame 100. Then, the lower mold frame 300 is removed. Finally, the locking mechanism 200 is released, the upper vacuum enclosure 120 and the upper mold plate 110 are separated, and the upper vacuum enclosure 120 is removed from the upper mold frame 100 with the aid of the connecting rod 210. The locking device for assisting in the removal of the upper mold frame vacuum enclosure ensures that the upper vacuum enclosure 120 remains fixed in the upper mold frame 100 after the lower mold frame 300 is removed, thereby protecting the mold box in the lower mold frame 300 and effectively avoiding the risk of the upper vacuum enclosure 120 automatically falling off and injuring the operator when the lower mold frame 300 is removed.

[0043] The steps for using the locking device for assisting in disassembling the upper mold frame vacuum enclosure are as follows: the locking mechanism 200 is installed on the upper vacuum enclosure 120. Before disassembling the lower mold frame 300, refer to Figure 1 and Figure 2 First, switch the locking mechanism 200 to the locking state to connect the upper vacuum enclosure 120 with the upper template 110, thereby fixing the upper vacuum enclosure 120 in the upper mold frame 100; after the upper vacuum enclosure 120 is locked, remove the lower mold frame 300 as a whole. After the lower mold frame 300 is disassembled, refer to Figure 3 and Figure 5 , switching the locking mechanism 200 to its initial state, releasing the lock between the upper vacuum enclosure 120 and the upper mold plate 110, and finally removing the upper vacuum enclosure 120 from the upper mold frame 100 by holding the connecting rod 210. The locking mechanism 200 effectively prevents the upper vacuum enclosure 120 from falling directly from the upper mold frame 100 when removing the lower mold frame 300, thereby striking the mold box of the lower mold frame 300 and injuring the operator.

[0044] The following is a detailed description of the structure and shape of the locking device for assisting in the removal of the upper mold frame vacuum enclosure:

[0045] In an optional solution of the embodiment of the present invention, the connecting rod 210 and the stop block 220 are slidably engaged.

[0046] Specifically, the connecting rod 210 can move along its own axial direction, and the connecting rod 210 and the stopper 220 are two separate structures. Of course, the connecting rod 210 and the stopper 220 are fixedly connected, which should also be within the protection scope of the embodiment of the present utility model.

[0047] The connecting rod 210 is slidably connected to the stopper 220 , so that the connecting rod 210 can be removed from the stopper 220 when not in use, and inserted into the stopper 220 when in use.

[0048] In an optional solution of the embodiment of the present invention, a blocking piece 212 is provided at one end of the connecting rod 210 away from the second locking hole 211 .

[0051] In an optional solution of the embodiment of the present invention, when the locking mechanism 200 is in the locked state, the blocking piece 212 abuts against the side wall of the blocking block 220 .

[0052] Specifically, the block 220 is provided with a sleeve hole, and the connecting rod 210 is inserted into the sleeve hole and slides with the sleeve hole; the outer diameter of the blocking piece 212 is larger than the diameter of the sleeve hole, so that the blocking piece 212 can abut against the side wall of the block 220 to achieve a limiting effect.

[0053] When the locking mechanism 200 is in the locked state, the blocking piece 212 abuts against the side wall of the block 220, and the second locking hole 211 of the connecting rod 210 is connected to the first locking hole 112; the blocking piece 212 realizes a limiting effect, avoiding the operator from having to move the connecting rod 210 multiple times to connect the second locking hole 211 with the first locking hole 112, thereby improving efficiency.

[0061] Specifically, the shape of the groove 113 is adapted to the shape of the locking protrusion 221; the side wall of the limiting protrusion 111 is recessed inward to form the groove 113, so that the locking protrusion 221 can enter the groove 113 when the stop block 220 rotates around the rotating shaft 240; the left and right side walls of the groove 113 can limit the axial movement of the locking protrusion 221 along the connecting rod 210.

[0062] The engaging protrusion 221 engages with the groove 113 to achieve the left and right limiting effect of the limiting protrusion 111 on the stopper 220 and improve the locking effect of the locking mechanism 200 .

[0063] As another embodiment, the stop block 220 is slidably engaged with the fixing block 230 .

[0064] In an optional solution of the embodiment of the present invention, multiple blocks 220 and multiple fixed blocks 230 are provided, and multiple fixed blocks 230 are arranged at intervals along the axial direction of the connecting rod 210. The multiple blocks 220 are movably connected to the multiple fixed blocks 230 in a one-to-one corresponding manner, and are all sleeved on the connecting rod 210.

[0065] Specifically, in this embodiment, there are two stoppers 220 and two fixing blocks 230; of course, other numbers of stoppers 220 and two fixing blocks 230 should also fall within the scope of protection of the present invention. Figure 2 The mounting protrusion 121 is provided with a T-shaped slot 122, and the side wall of the fixing block 230 is provided with an inserting protrusion 231, which is adapted to the T-shaped slot 122, so that the fixing block 230 can be installed in the T-shaped slot 122 without the need for fixing parts such as screws.

[0066] Multiple stoppers 220 and multiple fixing blocks 230 are provided, thereby enhancing the locking effect of the locking mechanism 200 .

[0067] An optional solution of the embodiment of the present invention further includes an upper base plate 130 and an upper heat insulation plate 140 , and the upper heat insulation plate 140 is located between the upper base plate 130 and the upper template 110 .

[0068] Specifically, see Figure 3 , upper front and rear outer baffle positioning blocks 150 are also provided below the upper mold frame 100.

[0069] The upper heat insulation board 140 achieves a heat insulation effect.

[0070] An optional solution of the embodiment of the present invention further includes a lower mold frame 300 , which includes a lower vacuum enclosure 310 , and one end of the upper vacuum enclosure 120 facing away from the upper template 110 abuts against the lower vacuum enclosure 310 .

[0071] Specifically, see Figure 6 The lower mold frame 300 also includes a lower mold plate 320, a lower support heat insulation board 330, a lower support 340, and a lower base plate 350. The lower mold plate 320 is located between the lower vacuum enclosure 310 and the lower support heat insulation board 330, and the lower support 340 is located between the lower support heat insulation board 330 and the lower base plate 350. In addition, the top of the lower mold frame 300 also includes lower left and right sliding positioning blocks 360 and lower rear outer baffle positioning blocks 370, and the bottom of the lower mold frame 300 also includes mold frame positioning pins 380.

[0072] The lower vacuum enclosure 310 , the lower template 320 , the lower support heat insulation board 330 , the lower support 340 and the lower bottom plate 350 form the lower mold frame 300 .

[0073] The following is a detailed description of the steps for using the locking device to assist in removing the upper mold frame vacuum enclosure:

[0074] The locking mechanism 200 is installed on the upper vacuum enclosure 120. Before removing the lower mold frame 300, first push the connecting rod 210 in the locking mechanism 200 upward, then push the connecting rod 210 to the left until it cannot be moved, and put the pin into the second locking hole 211 on the connecting rod 210. The locking mechanism 200 reaches the locked state, and the entire structure is locked to achieve the connection between the upper vacuum enclosure 120 and the upper template 110, thereby fixing the upper vacuum enclosure 120 in the upper mold frame 100; after the upper vacuum enclosure 120 is fixed, the lower mold frame 300 is completely After the lower mold frame 300 is dismantled, the previously locked locking mechanism 200 is unlocked and then pulled down to restore the position of the connecting rod 210, and the lock between the upper vacuum enclosure 120 and the upper template 110 is released. Finally, the operator can also remove the upper vacuum enclosure 120 from the upper mold frame 100 by holding the connecting rod 210. The fixation of the locking mechanism 200 effectively prevents the upper vacuum enclosure 120 from falling directly from the upper mold frame 100 and hitting the mold box of the lower mold frame 300 and injuring the operator when the lower mold frame 300 is dismantled.

[0075] After adding the auxiliary disassembly device, the safety of the disassembly process of the upper vacuum enclosure 120 has been greatly improved compared with the previous disassembly method; without changing the internal structure of the upper and lower mold frames 300, the convenience and safety of the disassembly process of the upper vacuum enclosure 120 are guaranteed. At the same time, the locking mechanism 200 is light and flexible, easy to operate, saving manufacturing costs while ensuring the stability and safety of the disassembly process. The installation of the locking mechanism 200 does not destroy the overall internal structure of the original mold frame, does not affect the normal use of the original mold frame, and effectively avoids the risk of the upper vacuum enclosure 120 hitting the mold box in the lower mold frame 300 when disassembling. The entire disassembly process can be achieved by one person, which improves work efficiency while ensuring the safety of the operator.

[0076] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0077] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art.
