Description

Technical Field

[0001] This utility model relates to the field of mold hoisting tools, and more specifically, to a rubber belt forming mold hook. Background Technology

[0002] Rubber belt molding dies are widely used in industrial production, and hooks play a crucial role as key tools in their installation, disassembly, and handling. Currently, rubber belt molding dies are mainly divided into two specifications: half-meter and one-meter. The traditional approach is to design dedicated hooks for each size of mold. While this method can meet basic usage requirements, it has many shortcomings.

[0003] First, the hooks lack versatility and are cumbersome to replace. Currently, half-meter and one-meter molds on the market require different specialized hooks, and their clamping structures are incompatible, making them non-substitutable. During production, when moving molds of different sizes, operators must first disassemble the old hooks and then install the new ones, severely impacting production efficiency and cycle time. Second, the hooks are costly and wasteful of resources. To lift molds of different sizes, companies need to equip themselves with two sets of hooks of different specifications, increasing procurement costs. Moreover, specialized hooks are prone to corrosion when idle, shortening their lifespan and increasing maintenance and replacement costs.

[0004] Therefore, developing a universal hook structure that is applicable to molding dies for rubber belts of different specifications and is easy to operate has significant practical value. Utility Model Content

[0005] To address the aforementioned technical problems in the existing technology, this utility model provides a rubber belt molding die hook. The die hook is compatible with molds of different specifications and has the advantages of low cost, high efficiency, and easy operation.

[0006] The specific technical solution of this utility model is as follows: In a first aspect, this utility model provides a hook for a rubber belt molding die, comprising: The hook body is a cylindrical support component, comprising a cylindrical upper part, a cylindrical middle part, and a frustum-shaped lower part arranged sequentially from top to bottom, and a blocking component is provided at the lower end of the frustum-shaped lower part; A half-meter mold hoisting assembly is fitted onto the lower part of the frustum shape and is used to hoist a half-meter rubber belt forming mold. A one-meter mold hoisting assembly is fitted into the middle of the cylinder and is used to hoist a one-meter rubber belt forming mold. The operation control assembly includes a connecting mechanism and several lifting operating components. The connecting mechanism is connected to the cylindrical upper part of the hook body and is used to connect to an external device to lift the mold hook. The several lifting operating components are respectively disposed on the one-meter mold hoisting assembly and the half-meter mold hoisting assembly, and are used to clamp and release the rubber belt forming mold by controlling the up and down lifting of the one-meter mold hoisting assembly or the half-meter mold hoisting assembly.

[0007] In one possible implementation, the one-meter mold hoisting assembly includes a one-meter mold wedge column, a one-meter mold sleeve, and several one-meter mold holders. The one-meter mold wedge column is fixedly connected to the outer circumferential surface of the cylindrical middle part of the hook body, and the column wall of the one-meter mold wedge column is thinner at the top and thicker at the bottom. The one-meter mold sleeve and several one-meter mold holders are located around the one-meter mold wedge column and can slide up and down along the axial direction of the one-meter mold wedge column. The upper part of several one-meter mold holders is sleeved in the internal cavity of the one-meter mold sleeve.

The first upper outer protruding ring is nested in the first middle cavity of the one-meter mold sleeve, and the first lower outer protruding ring is used to hold the hoisting structure of the one-meter specification rubber belt forming mold.

[0009] In one possible implementation, the half-meter mold hoisting assembly includes a half-meter mold sleeve and a plurality of half-meter mold holders. The half-meter mold sleeve and the plurality of half-meter mold holders are sleeved around the lower part of the frustum-shaped structure and can slide up and down along the axial direction of the hook body. The upper part of the half-meter mold holder is sleeved in the internal cavity of the half-meter mold sleeve, and the lower part of the half-meter mold holder is located outside the half-meter mold sleeve. Under the guidance of the lower part of the frustum-shaped structure of the hook body, the lower parts of the plurality of half-meter mold holders extend away from the hook body and retract towards the hook body. The lower ends of the plurality of half-meter mold holders are used to hold the hoisting structure of the half-meter specification rubber belt forming mold.

[0010] In one possible implementation, the internal cavity of the half-meter mold sleeve includes a second upper cavity, a second middle cavity, and a second lower cavity arranged sequentially from top to bottom. The second upper cavity is shaped like an inverted frustum, and the second middle cavity and the second lower cavity are both cylindrical. The diameter of the second middle cavity is larger than the lower diameter of the second upper cavity and the diameter of the second lower cavity. The upper and lower ends of several half-meter mold holders are respectively provided with a second upper outer protruding ring and a second lower outer protruding ring, and the second upper outer protruding ring and the second lower outer protruding ring face away from the hook body. The second upper outer protruding ring is nested in the second middle cavity of the half-meter mold sleeve, and the second lower outer protruding ring is used to hold the hoisting structure of the half-meter specification rubber belt forming mold.

[0011] In one possible implementation, the lifting control component is a handle, which is detachably connected to the half-meter mold sleeve or the one-meter mold sleeve, and is used to control the up-and-down sliding of the half-meter mold sleeve or the one-meter mold sleeve. The handle provides a convenient force application point for the operator to control the sliding of the sleeve. By manually operating the handle, the half-meter / one-meter mold sleeve and its matching bracket can be easily moved up and down along the axial direction of the hook body, reducing the difficulty of operation.

[0012] In one possible implementation, the connecting mechanism includes a threaded sleeve and a lifting ring, the upper part of the hook body has an external thread, the inner wall of the threaded sleeve is provided with an internal thread that mates with the external thread, and the lifting ring is connected to the outer wall of the threaded sleeve.

[0013] In one possible implementation, the operation control component further includes a locking mechanism connected to the one-meter mold hoisting component for locking the one-meter mold hoisting component when hoisting the half-meter rubber belt forming mold. In another possible implementation, the locking mechanism includes a locking ball, a spring, a stud, and a nut cooperating with the stud. The one-meter mold sleeve has a through hole.

The rubber belt forming mold lifting hook provided by this utility model integrates a one-meter mold lifting component and a half-meter mold lifting component on the same hook body, and realizes universal lifting of two specifications of molds through the lifting operation component. This solves the problem of the non-universality of traditional special hooks. One set of hooks can be compatible with both half-meter and one-meter rubber belt forming molds without the need to replace the hooks, which significantly improves the versatility of the rubber belt forming mold lifting hook.

[0015] 2. Compared with the traditional method that requires two sets of dedicated hooks, the cost of the single set of rubber belt forming mold hooks provided by this utility model is significantly reduced; at the same time, due to the increased frequency of use of the rubber belt forming mold hooks, the possibility of idle corrosion is reduced, the service life is extended, and the economic benefits are improved.

[0016] 3. The rubber belt forming mold hook provided by this utility model does not require changing the hook when transporting rubber belt forming molds of different specifications.

[0030] First, those skilled in the art should understand that the following embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0031] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0032] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] The specific technical solution of this utility model is as follows: In a first aspect, this utility model provides a hook for a rubber belt molding die, comprising: The hook body is a cylindrical support component, comprising a cylindrical upper part, a cylindrical middle part, and a frustum-shaped lower part arranged sequentially from top to bottom, and a blocking component is provided at the lower end of the frustum-shaped lower part; A half-meter mold hoisting assembly is fitted onto the lower part of the frustum shape and is used to hoist a half-meter rubber belt forming mold. A one-meter mold hoisting assembly is fitted into the middle of the cylinder and is used to hoist a one-meter rubber belt forming mold. The operation control assembly includes a connecting mechanism and several lifting operating components. The connecting mechanism is connected to the cylindrical upper part of the hook body and is used to connect to an external device to lift the mold hook. The several lifting operating components are respectively disposed on the one-meter mold hoisting assembly and the half-meter mold hoisting assembly, and are used to clamp and release the rubber belt forming mold by controlling the up and down lifting of the one-meter mold hoisting assembly or the half-meter mold hoisting assembly.

[0034] The rubber belt forming mold lifting hook provided by this utility model independently sets up a half-meter mold lifting component and a one-meter mold lifting component at the lower and middle parts of the hook body. The two sets of components can be operated independently, achieving compatibility of lifting two specifications of rubber belt forming molds with a single hook. One set of hooks can meet the lifting needs of two mold specifications, reducing equipment purchase costs and subsequent costs such as hook storage and maintenance, significantly reducing overall operating costs. Since the two lifting components are integrated on the same hook and work independently, frequent hook changes are unnecessary when alternately lifting different mold specifications, saving time and greatly improving the efficiency of mold lifting and handling. At the same time, the hook body is a cylindrical support component, providing stable structure and solid support to ensure stability during the lifting process. The cylindrical center of the hook body provides a stable installation base for the one-meter mold hoisting assembly. The sloping structure at the bottom of the frustum-shaped hook body guides the placement and sliding of the half-meter mold hoisting assembly. Combined with the blocking components on the bottom surface, the downward stroke of the half-meter mold hoisting assembly is limited, preventing it from detaching from the hook body. The operation control assembly unifies the connection to external devices and controls both sets of hoisting assemblies. Operators can easily clamp and release the two mold sizes using the lifting control components, making operation simple, easy to master, and simplifying the process.

[0035] In one possible implementation, the one-meter mold hoisting assembly includes a one-meter mold wedge column, a one-meter mold sleeve, and several one-meter mold holders. The one-meter mold wedge column is fixedly connected to the outer circumferential surface of the cylindrical middle part of the hook body, and the column wall of the one-meter mold wedge column is thinner at the top and thicker at the bottom. The one-meter mold sleeve and several one-meter mold holders are located around the one-meter mold wedge column and can slide up and down along the axial direction of the one-meter mold wedge column. The upper part of several one-meter mold holders is sleeved in the internal cavity of the one-meter mold sleeve. The lower part of several one-meter mold holders is located outside the one-meter mold sleeve. Under the guidance of the one-meter mold wedge column, the lower part of several one-meter mold holders can extend away from the hook body and retract towards the hook body. The lower end of several one-meter mold holders is used to lock the hoisting structure of the one-meter specification rubber belt forming mold. The "thin-top, thick-bottom" characteristic of the one-meter mold wedge column, combined with the up-and-down sliding of the one-meter mold sleeve, allows the one-meter mold holder to automatically extend and retract under the guidance of the wedge column's inclined structure when the sleeve slides along the wedge column. This eliminates the need for complex drive mechanisms. Multiple one-meter mold holders can share the weight of the one-meter rubber molding mold. Combined with the limiting effect of the one-meter mold sleeve on the upper end of the holder, this enhances the overall structural stability and service life of the one-meter mold hoisting assembly. Operators only need to control the up-and-down sliding of the sleeve to achieve the locking and unlocking of the holders through structural linkage. The operation is simple, easy to master, and improves work efficiency.

[0036] In one possible implementation, the internal cavity of the one-meter mold sleeve includes a first upper cavity, a first middle cavity, and a first lower cavity arranged sequentially from top to bottom. The first upper cavity and the first middle cavity are both cylindrical in shape, and the first lower cavity is frustum-shaped. The diameter of the first middle cavity is larger than the diameter of the first upper cavity and the upper end diameter of the first lower cavity. The upper and lower ends of several one-meter mold holders are respectively provided with a first upper outer protruding ring and a first lower outer protruding ring, and the first upper outer protruding ring and the first lower outer protruding ring face away from the hook body. The first upper outer protruding ring is nested in the first middle cavity of the one-meter mold sleeve, and the first lower outer protruding ring is used to hold the hoisting structure of the one-meter specification rubber belt forming mold. The one-meter mold holder and one-meter mold sleeve with the above structure can simultaneously drive the one-meter mold holder to move when the one-meter mold sleeve slides up and down, providing power for the extension or retraction of the lower end of the one-meter mold holder and ensuring coordinated action between the two; the first lower outer protruding ring of the lower end of the one-meter mold holder can directly fit and clamp with the hoisting structure of the one-meter mold, increasing the contact area and friction.

[0037] In one possible implementation, the half-meter mold hoisting assembly includes a half-meter mold sleeve and a plurality of half-meter mold holders. The half-meter mold sleeve and the plurality of half-meter mold holders are sleeved around the lower part of the frustum-shaped structure and can slide up and down along the axial direction of the hook body. The upper part of the half-meter mold holder is sleeved in the internal cavity of the half-meter mold sleeve, and the lower part of the half-meter mold holder is located outside the half-meter mold sleeve. Under the guidance of the lower part of the frustum-shaped structure of the hook body, the lower parts of the plurality of half-meter mold holders extend away from the hook body and retract towards the hook body. The lower ends of the plurality of half-meter mold holders are used to hold the hoisting structure of the half-meter specification rubber belt forming mold. When the half-meter mold sleeve slides up and down along the lower part of the frustum, the half-meter mold sleeve cooperates with the half-meter mold holder, and with the guide of the inclined surface of the lower part of the frustum, the lower part of the half-meter mold holder extends away from the hook body while moving downward, and retracts towards the hook body while moving upward, without the need for a complex drive mechanism; multiple half-meter mold holders can evenly bear the weight of the half-meter specification rubber belt forming mold, and with the limiting effect of the sleeve, improve the overall stability and service life of the lifting assembly.

[0038] In one possible implementation, the internal cavity of the half-meter mold sleeve includes a second upper cavity, a second middle cavity, and a second lower cavity arranged sequentially from top to bottom. The second upper cavity is shaped like an inverted frustum, and the second middle cavity and the second lower cavity are both cylindrical. The diameter of the second middle cavity is larger than the lower diameter of the second upper cavity and the diameter of the second lower cavity. The upper and lower ends of several half-meter mold holders are respectively provided with a second upper outer protruding ring and a second lower outer protruding ring, and the second upper outer protruding ring and the second lower outer protruding ring face away from the hook body. The second upper outer protruding ring is nested in the second middle cavity of the half-meter mold sleeve, and the second lower outer protruding ring is used to hold the hoisting structure of the half-meter specification rubber belt forming mold. The half-meter mold holder and half-meter mold sleeve with the above structure can simultaneously drive the half-meter mold holder to move when the half-meter mold sleeve slides up and down, providing power for the extension or retraction of the lower end of the half-meter mold holder and ensuring coordinated action between the two. The second lower outer protruding ring at the lower end of the half-meter mold holder can directly fit and clamp with the hoisting structure of the half-meter mold, increasing the contact area and friction, and preventing the half-meter specification rubber belt from slipping during hoisting.

[0039] In one possible implementation, the lifting control component is a handle, which is detachably connected to the half-meter mold sleeve or the one-meter mold sleeve, and is used to control the up-and-down sliding of the half-meter mold sleeve or the one-meter mold sleeve. The handle provides a convenient force application point for the operator to control the sliding of the sleeve. By manually operating the handle, the half-meter / one-meter mold sleeve and its matching bracket can be easily moved up and down along the axial direction of the hook body, reducing the difficulty of operation.

[0040] In one possible implementation, the connecting mechanism includes a threaded sleeve and a lifting ring. The upper part of the hook body has an external thread, and the inner wall of the threaded sleeve has an internal thread that mates with the external thread. The lifting ring is connected to the outer wall of the threaded sleeve. The lifting ring, as a component that directly connects to external lifting equipment (such as a gantry crane or overhead crane), provides a stable suspension point for the hook, ensuring the safe support of the mold weight during lifting. The threaded sleeve connects to the upper part of the hook body through the internal and external thread engagement, providing a solid mounting base for the lifting ring, forming a complete force chain of external equipment - lifting ring - threaded sleeve - hook body.

[0041] In one possible implementation, the operation control component further includes a locking mechanism connected to the one-meter mold hoisting component, used to lock the one-meter mold hoisting component when hoisting the half-meter rubber belt molding mold. When hoisting the half-meter abrasive rubber belt mold using the half-meter mold hoisting component, the locking mechanism can fix the position of the one-meter mold hoisting component, preventing interference with the hoisting operation of the half-meter mold hoisting component.

[0042] In one possible implementation, the locking mechanism includes a locking ball, a spring, a stud, and a nut that mates with the stud. The one-meter mold sleeve has a through hole. Both the spring and the locking ball are disposed within the through hole. The locking ball is positioned in the through hole near one end of the one-meter mold wedge-shaped post. The left and right ends of the spring respectively abut against the stud and the locking ball. The nut is fixed to the outer wall of the one-meter mold sleeve. One end of the stud passes through the nut and is inserted into the through hole, while the other end of the stud is outside the through hole. Through the engagement of the locking ball and the one-meter mold wedge-shaped post, under the spring force, the locking ball can fix the one-meter mold sleeve in a specific position, preventing accidental slippage of the one-meter mold sleeve during hoisting and ensuring a stable locking state of the one-meter mold holder on the mold. The spring provides continuous elastic force to keep the locking ball in contact with the one-meter mold wedge-shaped post.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0044] This embodiment provides a hook for a rubber belt molding die, such as... Figure 1-3As shown, it includes a hook body 1, a half-meter mold hoisting assembly 2, a one-meter mold hoisting assembly 3, and an operation control assembly. The operation control assembly includes a connecting mechanism 4, a locking mechanism 5, and a lifting operation component. The one-meter mold hoisting assembly 3 and the half-meter mold hoisting assembly 2 work independently and do not affect each other when they are in operation.

[0045] like Figure 1 , 2 As shown in Figure 4, the hook body 1 is composed of a cylindrical upper part 11 with external threads, a cylindrical middle part 12 and a frustum-shaped lower part 13, and a blocking member 14 is provided on the bottom surface of the frustum-shaped lower part 13; the hook body 1, as the core support component, is made of steel to ensure the lifting strength, and the overall length of the hook body 1 can be designed according to the lifting requirements of the rubber belt forming mold.

[0046] like Figure 1 , 2 As shown, the upper cylindrical part 11 of the hook body 1 is connected to the threaded sleeve 41 by an external thread. The upper end of the upper cylindrical part 12 of the hook body 1 has an external thread. The inner wall of the threaded sleeve 41 is provided with an internal thread that matches the external thread. The upper part of the threaded sleeve 41 is fixedly connected to the lifting ring 42. The threaded sleeve 41 and the lifting ring 42 together form the connecting mechanism 4. The lifting ring 42, as a component that directly connects to external lifting equipment (such as gantry cranes or overhead cranes), provides a stable suspension point for the hook.

[0047] like Figure 1-8As shown, a one-meter mold lifting assembly 3 is fitted around the cylindrical middle part 12 of the hook body 1 to achieve the lifting operation of a one-meter specification rubber belt forming mold; the one-meter mold lifting assembly 3 consists of a one-meter mold wedge column 31, a one-meter mold sleeve 32, and two one-meter mold holders 33; the one-meter mold wedge column 31 is a hollow column with thin walls at the top and thick walls at the bottom, and is fixedly connected to the outer circumference of the cylindrical middle part 12 of the hook body 1; the one-meter mold sleeve 32 and the two one-meter mold holders 33 are fitted around the one-meter mold wedge column 31 and can slide up and down along the axial direction of the one-meter mold wedge column 31, and the two one-meter mold holders 33 are symmetrically fitted on both sides of the one-meter mold wedge column 31; the internal cavity of the one-meter mold sleeve 32 includes a first upper cavity 321, a first middle cavity 322, and a first lower cavity arranged sequentially from top to bottom. Cavity 323, the first upper cavity 321 and the first middle cavity 322 are both cylindrical in shape, and the first lower cavity 323 is shaped like a frustum of a circle. The frustum of a circle shape of the first lower cavity 323 can better fit with the one-meter mold wedge column 31. The diameter of the first middle cavity 322 is larger than the diameter of the first upper cavity 321, and the upper diameter of the first lower cavity 323 is smaller than the diameter of the first middle cavity 322. The upper and lower ends of the two one-meter mold holders 33 are respectively provided with a first upper outer protruding ring 331 and a first lower outer protruding ring 332, and the first upper outer protruding ring 331 and the first lower outer protruding ring 332 face away from the hook body 1. The first upper outer protruding ring 331 is nested in the first middle cavity 322 of the one-meter mold sleeve 33, and the first lower outer protruding ring 332 is used to hold the hoisting structure of the one-meter specification rubber belt forming mold.

[0048] A locking mechanism 5 is also installed on the one-meter mold sleeve 32. The locking mechanism 5 includes a locking ball 54, a spring 53, a stud 51, and a nut 52 that mates with the stud 51. The one-meter mold sleeve 32 has a through locking mechanism mounting hole 55. The spring 53 and the locking ball 54 are both located in the locking mechanism mounting hole 55. The locking ball 54 is located at one end of the locking mechanism mounting hole 55 near the one-meter mold wedge post 31. The left and right ends of the spring 53 abut against the stud 51 and the locking ball 54, respectively. The nut 52 is fixed to the one-meter mold. On the outer wall of the sleeve 32, the right end of the stud 51 passes through the nut 52 and is inserted into the locking mechanism mounting hole 55, while the left end of the stud 51 is located outside the locking mechanism mounting hole 55. The one-meter mold sleeve 32 is also provided with a lifting operation component, which is a one-meter mold handle 6. The one-meter mold sleeve 32 is provided with a one-meter handle mounting hole 61 with internal threads. One end of the one-meter mold handle 6 has an external thread that matches the internal thread. The one-meter mold handle 6 is connected to the one-meter mold sleeve 32 through the cooperation of the internal and external threads.

[0049] Lifting process for a 1-meter rubber belt forming mold: Clamping process: The operator lifts the one-meter mold sleeve 32 upwards using the one-meter mold handle 6. The one-meter mold sleeve 32 drives the one-meter mold holder 33 upwards. Simultaneously, guided by the inclined structure of the one-meter mold wedge column 31, the first lower outer protruding ring 332 of the one-meter mold mounting holder 33 retracts towards the hook body. The entire hook body 1 is controlled to descend, so that the retracted one-meter mold holder 33 enters the hoisting part of the one-meter specification rubber belt forming mold. Then, the one-meter mold handle 6 is released, and the one-meter mold sleeve 32 slides downwards. During the downward sliding process, the inclined outer wall of the one-meter mold wedge column 31 pushes the first lower outer protruding ring 332 of the one-meter mold holder 33 to extend outwards. The first lower outer protruding ring 332 of the one-meter mold holder 33 and the outer wall of the one-meter mold sleeve 32 cooperate to clamp the hoisting structure of the one-meter specification rubber belt forming mold. The one-meter mold can then be hoisted through the gantry frame connected to the lifting ring 42. Unlocking process: After the one-meter rubber belt forming mold is transported to the target position, the one-meter mold sleeve 32 is lifted again by the one-meter mold handle 6. At the same time, the hook body 1 is lowered appropriately. The first lower outer protruding ring 332 of the one-meter mold holder 33 retracts inward under the guidance of gravity and the inclined structure of the one-meter mold wedge column 31. The first lower outer protruding ring 332 retracts to the bottom of the one-meter mold sleeve 32, releasing the clamping of the one-meter rubber belt forming mold. Then the rubber belt forming mold hook can be pulled out from the lifting part of the one-meter rubber belt forming mold to complete the unlocking.

[0050] like Figure 1-4 and Figure 9-12As shown, a half-meter mold lifting assembly 2 is fitted onto the lower part 13 of the frustum-shaped hook body 1 to lift a half-meter rubber belt forming mold. The half-meter mold lifting assembly 2 consists of a half-meter mold sleeve 21 and two half-meter mold holders 22. The half-meter mold sleeve 21 and the two half-meter mold holders 22 are fitted around the lower part 13 of the frustum-shaped hook body 1 and can slide up and down along the axial direction of the hook body 1. The two half-meter mold holders 22 are symmetrically arranged on both sides of the lower part 13 of the frustum-shaped hook body 1. The upper ends of the two half-meter mold holders 22 are located inside the half-meter mold sleeve 21, and the lower ends are located outside the half-meter mold sleeve 21. The internal cavity of the half-meter mold sleeve 21 includes a second upper cavity 211, a second middle cavity 212, and a second lower cavity 213 arranged sequentially from top to bottom. The second upper cavity 211 is shaped like an inverted frustum, and the second middle cavity 212 and the second lower cavity 213 are both cylindrical. The diameter of the second middle cavity 212 is larger than the diameter of the lower end of the second upper cavity 211, and the diameter of the second lower cavity 213 is smaller than the diameter of the second middle cavity 212. The upper and lower ends of the half-meter mold holder 22 are respectively provided with a second upper outer protruding ring 221 and a second lower outer protruding ring 222 away from the hook body 1. The second upper outer protruding ring 221 is nested in the second middle cavity 212 of the half-meter mold sleeve 21, and the second lower outer protruding ring 222 is suitable for holding the hoisting structure of the half-meter specification rubber belt mold. The half-meter mold sleeve 21 is also provided with a lifting operation component, which is a half-meter mold handle 7. The half-meter mold sleeve 21 is provided with a half-meter handle mounting hole 71 with internal thread. One end of the half-meter mold handle 7 has an external thread that matches the internal thread. The half-meter mold handle 7 is connected to the half-meter mold sleeve 21 through the cooperation of the internal thread and the external thread.

[0051] Lifting process for half-meter rubber belt forming mold: The hoisting and unlocking process of the half-meter rubber belt forming mold: First, the operator operates the one-meter mold handle 6 to lift the one-meter mold sleeve 32 upwards. The one-meter mold sleeve 32 moves the one-meter mold holder 33 upwards until the locking mechanism 5 aligns with the top of the one-meter mold wedge post 31. Then, the operator rotates the stud 51 to lock the locking ball 54 under the elastic force of the spring 53, thus locking it to the top of the one-meter mold wedge post 31. This completes the locking action, fixing the one-meter mold holder 33 and the one-meter mold sleeve 32 to prevent subsequent interference with the hoisting of the half-meter rubber belt forming mold. Next, the operator lifts the half-meter mold sleeve 21 upwards using the half-meter mold handle 7. The half-meter mold sleeve 21 moves the half-meter mold holder 22 upwards, and simultaneously, the second lower end of the half-meter mold holder 22... The outer protruding ring 222 retracts towards the hook body under the guidance of the inclined structure of the lower part 13 of the frustum-shaped hook body 1; the entire hook body 1 is controlled to descend, so that the half-meter mold holder 22, which is in the retracted state, enters the hoisting part of the half-meter rubber belt forming mold; then the half-meter mold handle 7 is released, and the half-meter mold sleeve 21 slides downward. During the downward sliding process, the inclined outer wall of the lower part 13 of the frustum-shaped hook body 1 pushes the second lower end of the outer protruding ring 222 of the half-meter mold holder 22 to extend away from the hook body. The second lower end of the outer protruding ring 222 of the half-meter mold holder 22 and the outer wall of the half-meter mold sleeve 32 cooperate to lock the hoisting structure of the half-meter rubber belt forming mold; the half-meter rubber belt forming mold can be hoisted by the gantry frame connected to the lifting ring 42. Unlocking process: After the half-meter rubber belt forming mold is transported to the target position, the half-meter mold sleeve 21 is lifted again by the half-meter mold handle 7. At the same time, the hook body 1 is lowered appropriately. The second lower end of the half-meter mold holder 22's outer protruding ring 222 retracts inward under the guidance of gravity and the inclined outer wall of the right circular frustum lower part 13 of the hook body 1. The second lower end of the outer protruding ring 222 retracts to below the half-meter mold sleeve 21, releasing the clamping of the half-meter rubber belt forming mold. Then, the rubber belt forming mold hook can be pulled out from the lifting part of the half-meter rubber belt forming mold to complete the unlocking.
