A method for removing the bottom mold

Abstract

The present invention belongs to the technical field of shoe manufacturing, and provides a method for disassembling a bottom mold. The disassembly is carried out by using a bottom mold disassembly assistor. Through the rotation of the rotating mechanism, first, the reciprocating linear motion of the screw can be realized, thereby driving the synchronous movement of the force arm mechanism. Furthermore, the clamping member at the front end of the force arm mechanism clamps the bottom mold, and then the bottom mold is driven to move towards the support frame, so that the bottom cap at the bottom of the bottom mold is separated from the inlaid small groove of the bottom mold platform. Finally, the bottom mold can be smoothly removed from the bottom mold platform by using tools, saving time and improving work efficiency; and during the disassembly process, it is not easy to scald the operators. The bottom mold disassembly method can be positioned through the positioning mechanism during the disassembly of heavy objects, preventing the force arm mechanism from deviating up, down, left, or right, solving the problem of being unable to tightly clamp the bottom mold, and by fixedly connecting adjacent two main force arms, it can ensure the synchronous movement of the two main force arms.

Description

Technical Field

[0001] The present invention belongs to the technical field of shoe manufacturing, and particularly relates to a method for disassembling a bottom mold. Background Art

[0002] After the Desma shoe-making machine stops operating, the bottom mold of Desma needs to be maintained and repaired. The bottom mold has to be removed from the bottom mold platform. Since the temperature of the bottom mold remains at 160 - 170 °C during production operations, it is too hot to be directly removed. It needs to be left to cool down before it can be taken off the bottom mold platform. However, cooling down takes time and affects work efficiency. Disassembling at high temperature is likely to scald the staff, which does not meet the requirements of the occupational health and safety management system. If time is tight, a crowbar has to be used to disassemble the bottom mold, which is likely to damage the pattern on the bottom mold and affect the service life of the bottom mold. Summary of the Invention

[0003] The purpose of the present invention is to provide a method for disassembling a bottom mold to overcome the above-mentioned technical problems existing in the prior art.

[0004] To this end, the technical solution provided by the present invention is as follows:

[0005] A method for disassembling a bottom mold, which uses a bottom mold disassembly assistor for disassembly. The bottom mold disassembly assistor includes a screw rod, a support frame, and a force arm mechanism. The screw rod passes through the support frame. One end of the screw rod is connected with a rotation mechanism, and the other end of the screw rod is connected with the end of the force arm mechanism. A clamping member is provided at the front end of the force arm mechanism. The rotation mechanism is used to drive the screw rod to perform linear reciprocating motion;

[0006] It includes the following steps:

[0007] Step 1) After the shoe-making machine stops working, press the button to move the side molds on both sides of the bottom mold platform to both sides;

[0008] Step 2) Place the bottom mold disassembly assistor on the bottom mold platform through the support frame, and make the force arm mechanism located on the bottom mold;

[0009] Step 3) Rotate the rotation mechanism. First, make the screw rod move linearly and drive the force arm mechanism to gradually move towards the direction close to the support frame until the clamping member clamps the front end of the bottom mold. Then continue to rotate the rotation mechanism to move the bottom cap under the bottom mold from the small groove matching the bottom cap to the large groove. After that, stop rotating the rotation mechanism;

[0010] Step 4) Rotate the rotation mechanism in the reverse direction to increase the distance between the force arm mechanism and the support bracket, remove the bottom mold disassembly assistor, and then use tools to remove the bottom mold to complete the disassembly.

[0011] The force arm mechanism includes a connecting plate and a main force arm. The main force arm is fixedly arranged on one side of the connecting plate. There are at least two main force arms arranged in parallel. The screw rod is fixedly arranged in the upper middle part of the other side of the connecting plate. Both the main force arm and the screw rod are perpendicular to the connecting plate. The connecting plate is higher than the support frame, and the main force arm is arranged on the upper part of the support frame.

[0012] The rotation mechanism includes a rotating section and a rotating handle. The rotating handle is fixedly arranged on the rotating section. One end of the rotating section is connected to the support frame through a bearing. The rotating section is sleeved on the screw rod and connected through a thread.

[0013] On the upper part of one side of the support frame close to the force arm mechanism, heat insulation blocks are symmetrically and fixedly arranged, and on the lower part, support platforms are symmetrically and fixedly arranged. The front ends of the heat insulation blocks and the support platforms are flush.

[0014] The clamping member is a fixed rod, and the fixed rod is fixedly connected to the main force arm and arranged vertically downward.

[0015] It further includes a positioning mechanism. The positioning mechanism includes a positioning plate and a positioning rod. The positioning plate is fixedly arranged on the support frame and is arranged between the support frame and the connecting plate. One end of the positioning rod is fixedly arranged at the top of the positioning plate, and the other end of the positioning rod passes through the connecting plate and is located between two main force arms. The length of the positioning rod is less than that of the main force arm.

[0016] Adjacent two main force arms are fixedly connected through a connecting member.

[0017] The heat insulation block is made of hardwood.

[0018] The beneficial effects of the present invention are:

[0019] The method for disassembling the bottom mold provided by the present invention uses a bottom mold disassembly aid for disassembly. Through the rotation of the rotation mechanism, first, the reciprocating linear motion of the screw rod can be realized, thereby driving the synchronous motion of the force arm mechanism. Further, the clamping member at the front end of the force arm mechanism clamps the bottom mold, and then drives the bottom mold to move towards the support frame, so that the bottom cap at the bottom of the bottom mold is disengaged from the inlaid small groove of the bottom mold platform. Finally, the bottom mold can be smoothly removed from the bottom mold platform with tools, saving time and improving work efficiency; and during the disassembly process, it is not easy to scald the operators.

[0020] During the disassembly process of this bottom mold disassembly method, positioning is carried out through the positioning mechanism, which can prevent the force arm mechanism from deviating up, down, left, and right, solve the problem of being unable to tightly clamp the bottom mold, and by fixedly connecting adjacent two main force arms, it can ensure the synchronous movement of the two main force arms.

[0021] In the present invention, heat insulation blocks and support platforms are symmetrically arranged at the upper and lower parts of the support platform respectively, and the front ends of the support platform and the heat insulation blocks are flush. The upper ends of the heat insulation blocks abut against the side formworks on both sides, the support platform supports on the bottom formwork platform, and the front end of the support platform also closely abuts against the side formworks on both sides, so as to ensure that when the bottom formwork is disassembled, the bottom formwork disassembly auxiliary device can operate stably on the bottom formwork platform.

[0028] Embodiment 1:

[0029] This embodiment provides a method for disassembling the bottom formwork, which is disassembled by using a bottom formwork disassembly auxiliary device. The bottom formwork disassembly auxiliary device includes a screw 1, a support frame 4 and a force arm mechanism. The screw 1 passes through the support frame 4. One end of the screw 1 is connected with a rotating mechanism, the other end of the screw 1 is connected with the end of the force arm mechanism, and a clamping member is arranged at the front end of the force arm mechanism. The rotating mechanism is used to drive the screw 1 to perform linear reciprocating motion;

[0030] It includes the following steps:

[0031] Step 1) After the shoe-making machine stops working, the start button makes the side molds on both sides of the bottom mold platform move to both sides;

[0032] Step 2) Place the bottom mold disassembly aid on the bottom mold platform through the support frame 4 so that the force arm mechanism is located on the bottom mold;

[0033] Step 3) Rotate the rotating mechanism. First, make the screw rod 1 move linearly and drive the force arm mechanism to gradually move in the direction close to the support frame 4 until the clamping piece clamps the front end of the bottom mold. Then continue to rotate the rotating mechanism to move the bottom cap under the bottom mold from the small groove matching the bottom cap to the large groove. After that, stop rotating the rotating mechanism;

[0034] Step 4) Rotate the rotating mechanism in the reverse direction to increase the distance between the force arm mechanism and the support bracket, remove the bottom mold disassembly aid, and then use tools to remove the bottom mold to complete the disassembly.

[0035] For the bottom mold disassembly method provided by the present invention, the bottom mold disassembly aid is used for disassembly. By rotating the rotating mechanism, first, the reciprocating linear motion of the screw rod 1 can be realized to drive the synchronous movement of the force arm mechanism. Furthermore, the clamping piece at the front end of the force arm mechanism clamps the bottom mold. Then, drive the bottom mold to move in the direction close to the support frame 4 so that the bottom cap at the bottom of the bottom mold is separated from the inlaid small groove of the bottom mold platform. Finally, the bottom mold can be smoothly removed from the bottom mold platform with tools, saving time and improving work efficiency; and during the disassembly process, it is not easy to scald the operators.

[0036] Embodiment 2:

[0037] Based on Embodiment 1, this embodiment provides a bottom mold disassembly method. The force arm mechanism includes a connecting plate 5 and a main force arm 8. The main force arm 8 is fixedly arranged on one side of the connecting plate 5. The main force arm 8 has at least two and is arranged in parallel. The screw rod 1 is fixedly arranged in the upper middle part of the other side of the connecting plate 5. The main force arm 8 and the screw rod 1 are both perpendicular to the connecting plate 5. The connecting plate 5 is higher than the support frame 4, and the main force arm 8 is arranged on the upper part of the support frame 4.

[0038] As Figure 1 shown, the connecting plate 5 is used to connect the screw rod 1 and the main force arm 8, so that the linear motion of the screw rod 1 drives the main force arm 8 to move by the connecting plate 5, making the clamping piece gradually approach and clamp the bottom mold. The screw rod 1 is fixedly arranged in the upper middle part of the connecting plate 5 to prevent the force arm mechanism from rotating and being unable to clamp the bottom mold.

[0039] The length of the main force arm 8 is 5 cm more than the length of the bottom mold, so that it is easy to place the bottom mold disassembly aid on the bottom mold.

[0040] Embodiment 3:

[0041] On the basis of Embodiment 1, this embodiment provides a method for disassembling the bottom mold. The rotating mechanism includes a rotating section 3 and a rotating handle 2. The rotating handle 2 is fixedly arranged on the rotating section 3. One end of the rotating section 3 is connected to the support frame 4 through a bearing, and the rotating section 3 is sleeved on the screw rod 1 and connected by threads.

[0042] The rotating section 3 rotates relative to the support frame 4 without relative displacement. By rotating the rotating handle 2, the rotating section 3 rotates through the bearing, and the internal thread of the rotating section 3 drives the screw rod 1 to rotate for linear motion.

[0043] Embodiment 4:

[0044] On the basis of Embodiment 1, this embodiment provides a method for disassembling the bottom mold. On the upper part of one side of the support frame 4 close to the force arm mechanism, heat insulation blocks 6 are symmetrically and fixedly arranged, and on the lower part, support platforms 7 are symmetrically and fixedly arranged. The front ends of the heat insulation blocks 6 and the support platforms 7 are flush.

[0045] As Figure 1 shown, in this embodiment, the support frame 4 is made of steel structure, which plays a role in connecting the force arm mechanism and the rotating section 3 and is used to support the stability of the device. The center of the support frame 4 is connected to the screw rod 1 and the rotating section 3. One end of the screw rod 1 is fixed on the connecting plate 5 of the force arm mechanism, and the rotating handle 2 is installed on the rotating section 3. Rotating the rotating handle 2 can make the screw rod 1 contract freely.

[0046] Since the temperature of the bottom mold remains at 160 - 170 °C during production operations and is relatively high, two heat insulation blocks 6 are installed at the upper ends on both sides of the support frame 4 to play a heat insulation role. There are two support platforms 7 at the lower end, and the front ends of the support platforms 7 and the heat insulation blocks 6 are on the same horizontal line. In this way, during operation, it can be ensured that the device will not be unstable when operating on the bottom mold platform. In this embodiment, the heat insulation blocks 6 are made of hardwood.

[0047] The usage process is as follows:

[0048] Step 1) After the Desma shoe-making machine stops working, press the button to move the side molds on both sides of the bottom mold platform to both sides;

[0049] Step 2) Place the bottom mold disassembly auxiliary device on the bottom mold platform. At this time, the support frame 4 is placed on the bottom mold platform through the lower ends of the support platforms 7, the front ends of the heat insulation blocks 6 and the support platforms 7 are abutted against the side molds on both sides, and the force arm mechanism is placed on the bottom mold;

[0050] Step 3) Rotate the rotating handle 2, and the screw rod 1 drives the force arm mechanism to move towards the direction close to the support frame 4, so that the clamping member clamps the front end of the bottom mold. Continue to rotate the rotating handle 2 until the bottom cap under the bottom mold moves from the small groove of the inlaid bottom mold platform to the large groove, and then stop rotating the rotating handle 2;

[0051] Step 4) Rotate the handle 2 in the reverse direction to increase the distance between the lever mechanism and the support bracket, remove the disassembly bottom die auxiliary device, and then use tools to remove the bottom die.

[0052] Among them, there is a protruding bottom cap at the center of the bottom of the bottom die. Similarly, there is a small groove on the bottom die platform that matches the bottom cap of the bottom die (in this way, after the bottom die is placed on the bottom die platform, the bottom die inlay of the bottom die can be embedded in the small groove of the bottom die platform without deviation). In addition, a large groove is provided on the bottom die platform, and the large groove is communicated with the small groove (similar to a gourd shape). During disassembly, the bottom cap can enter the large groove, facilitating the removal of the bottom die.

[0053] Embodiment 5:

[0054] Based on Embodiment 2, this embodiment provides a method for disassembling the bottom die. The clamping member is a fixed rod 9, and the fixed rod 9 is fixedly connected to the main lever 8 and is arranged vertically downward.

[0055] The function of the fixed rod 9 is to be stuck at the front end of the bottom die. The fixed rod 9 needs to have a certain length to clamp the bottom die tightly.

[0056] Since the front end of the bottom die is arc-shaped, the clamping member can preferably be an arc-shaped plate that matches the arc shape of the front end of the bottom die. In order to increase friction, there can be patterns, etc. inside the arc-shaped plate.

[0057] Embodiment 6:

[0058] Based on Embodiment 2, this embodiment provides a method for disassembling the bottom die, which further includes a positioning mechanism. The positioning mechanism includes a positioning plate 11 and a positioning rod 10. The positioning plate 11 is fixedly arranged on the support frame 4 and is located between the support frame 4 and the connecting plate 5. One end of the positioning rod 10 is fixedly arranged at the top of the positioning plate 11, and the other end of the positioning rod 10 passes through the connecting plate 5 and is located between the two main levers 8. The length of the positioning rod 10 is less than that of the main lever 8.

[0059] The positioning rod 10 is to prevent the lever mechanism from deviating up, down, left, or right. Since the front end of the bottom die is arc-shaped, during use, the function of the fixed rod 9 is to be stuck at the front end of the bottom die. Due to the certain spacing of the clamping member, only by ensuring that the lever mechanism does not deflect can the clamping member be stuck at the front end of the bottom die under stable conditions.

[0060] Embodiment 7:

[0061] Based on Embodiment 2, this embodiment provides a method for disassembling the bottom die, and adjacent two of the main levers 8 are fixedly connected through a connecting member.

[0062] The fixed connection between adjacent two main levers 8 can ensure the synchronous movement of the two main levers 8.

[0063] The above examples are only illustrative of the present invention and do not constitute a limitation on the scope of protection of the present invention. Any design identical or similar to the present invention falls within the scope of protection of the present invention.
