Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold disassembly tool. Background Art

[0002] In the field of mold manufacturing and use, mold disassembly is an indispensable part of the production process. With the rapid development of the manufacturing industry, mold complexity and precision requirements are increasing, making mold disassembly more difficult. In particular, molds used in high-temperature and high-pressure environments often develop adhesion between the mold cavity and the mold after a period of use, making mold disassembly extremely difficult.

[0003] At present, there are two main mainstream methods of mold disassembly on the market: one is to use original disassembly equipment for disassembly, and the other is to disassemble manually using traditional bolt tools. However, both methods have significant defects. Although the use of original disassembly equipment is efficient, the high cost and specific adaptability to different types of molds make it not economical and practical in actual applications. On the other hand, although the manual disassembly method using traditional bolt tools is relatively low in cost, it is inefficient and has poor stability. Especially when the mold is tightly bonded to the mold cavity and can only be disassembled at the opening on one side of the mold cavity, it is difficult to ensure effective disassembly and there is a risk of damage to the mold. In addition, the long-term operation of the molding machine may cause the degree of adhesion between the mold and the mold cavity to a level that cannot be disassembled manually, further exacerbating the difficulty of disassembly. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies in the existing technology, and its main purpose is to provide a mold disassembly tool, which solves the technical problems of high cost and limited adaptability of using original disassembly equipment, and low efficiency, poor stability and easy damage to the mold when manually using traditional bolt tools to disassemble the mold when disassembling at the single-side opening of the mold cavity.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The utility model discloses a mold disassembly tool, which is used for disassembling a mold on a molding machine. The molding machine is provided with a mold cavity, the mold is mounted on the mold cavity, an abutment limit block is provided on the opening side of the mold cavity, and a placement groove is formed between the abutment limit block and the opening side of the mold cavity. The disassembly tool comprises:

[0008] An operating screw is threadedly mounted on the stopper, one end of the operating screw passes through the stopper and is provided with a protruding disassembly screw coaxial with the operating screw, a first threaded hole adapted to the disassembly screw is formed on the mold, and the thread directions of the operating screw and the disassembly screw are opposite;

[0009] An operating block is arranged at an end of the operating screw rod away from the disassembly screw rod.

[0010] As a preferred solution, the disassembly tool has an initial state, an installation state and a working state;

[0011] When the disassembly tool is in the initial state, the stopper abuts against the opening side of the mold cavity, and one end of the disassembly screw is not screwed into the first threaded hole;

[0012] When the disassembly tool is in the installed state, the stopper abuts against the abutment limit block, one end of the disassembly screw is screwed into and installed in the first threaded hole, and the end of the disassembly screw screwed into and installed in the first threaded hole does not abut against the bottom of the first threaded hole;

[0013] When the disassembly tool is in the working state, the stopper provides an outward pulling force for the mold, and the pulling force is used to separate the mold from the mold cavity.

[0014] As a preferred solution, the rod diameter of the operating screw is larger than the rod diameter of the disassembly screw.

[0015] As a preferred solution, a second threaded hole is opened in the middle of the block, the operating screw is installed on the second threaded hole, the thread direction of the operating screw is consistent with that of the second threaded hole, and the thread direction of the disassembly screw is consistent with that of the first threaded hole.

[0018] As a preferred solution, grooves are provided on both sides of the stopper, and guide steps corresponding to the grooves are provided on the molding machine, and the stopper can move along the length direction of the guide steps.

[0019] As a preferred solution, the geometric size of the operating block is larger than the rod diameter of the operating screw, and the surface of the operating block is covered with a rough texture layer.

[0020] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0021] 1. Improve disassembly efficiency and reduce costs: By introducing an operating block, a stopper, an operating screw, and a disassembly screw, and making the thread directions of the operating screw and the disassembly screw opposite, not only is the efficient disassembly of the mold improved, and production efficiency is increased, but the overall structure of the disassembly tool is also optimized, which greatly reduces manufacturing costs compared to using original disassembly equipment. At the same time, the versatility and adaptability of the disassembly tool are improved, eliminating the need to equip each mold with a specific disassembly device, further reducing overall operating costs.

[0022] 2.

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0035] In the field of mold manufacturing and use, mold disassembly is a key step in the production process. With the increase in mold complexity and precision requirements, especially in high temperature and high pressure environments, adhesion is likely to occur between the mold and the mold cavity, making disassembly particularly complicated. Currently, there are two main disassembly methods on the market: disassembly with original equipment and disassembly with manual bolt tools. However, although original equipment is efficient, it is costly and has poor adaptability; although manual disassembly is low-cost, it is inefficient and has difficulty dealing with situations where the mold and the mold cavity are tightly bonded, which can easily lead to mold damage. In particular, long-term operation of the molding machine may aggravate the degree of adhesion between the mold and the mold cavity, and manual disassembly becomes almost impossible when the mold can only be disassembled at the opening on one side of the mold cavity.

[0036] To resolve the above issues, please refer to Figures 1 to 6 The present invention provides a mold disassembly tool for disassembling a mold 11 on a molding machine. The molding machine is provided with a mold cavity 10, and the mold 11 is mounted on the mold cavity 10. An abutment limit block 13 is provided on the opening side of the mold cavity 10, and a placement groove 12 is formed between the abutment limit block 13 and the opening side of the mold cavity 10. The disassembly tool 20 includes:

[0037] The stopper 21 is arranged in the placement groove 12 to provide a disassembly fulcrum to ensure a stable support point during the disassembly process and ensure that the mold 11 and the mold cavity 10 can be stably separated.

[0038] The operating screw 22 is threadedly mounted on the stopper 21. One end of the operating screw 22 passes through the stopper 21 and is provided with a disassembly screw 221 coaxial with the operating screw 22, so that the disassembly screw 221 and the operating screw 22 can rotate synchronously and coaxially. A first threaded hole 111 is provided on the mold 11 to match the disassembly screw 221. This adaptability ensures that the disassembly screw 221 can be smoothly screwed in or out of the mold 11. The thread direction of the operating screw 22 is opposite to that of the disassembly screw 221. This design enables the stopper 21 to cooperate with the abutment limit block 13 when the mold 11 is disassembled. The force provided by rotating the operating screw 22 is converted into an outward pulling force acting on the mold 11 through the disassembly screw 221, thereby realizing the separation of the mold 11 and the mold cavity 10.

[0039] The operating block 23 is provided at one end of the operating screw 22 away from the disassembly screw 221 to provide a convenient rotation operating point so that the operator can easily and accurately control the disassembly process.

[0040] In this embodiment, the disassembly tool 20 has an initial state, an installation state, and a working state.

[0041] See also Figure 4 When the disassembly tool 20 is in the initial state, the stopper 21 abuts against the opening side of the mold cavity 10 to ensure the position stability of the disassembly tool 20 in the preparation stage, and one end of the disassembly screw 221 is not screwed into the first threaded hole 111.

[0042] See also Figure 5 When the disassembly tool 20 is in the installed state, the stop block 21 abuts against the abutment limit block 13. At this time, there is no mutual extrusion force between the stop block 21 and the abutment limit block 13. The abutment limit block 13 provides a limit point for the stop block 21 to ensure the stable installation of the disassembly tool 20. One end of the disassembly screw 221 is screwed into and installed in the first threaded hole 111. The end of the disassembly screw 221 screwed into and installed in the first threaded hole 111 does not abut against the bottom of the first threaded hole 111, ensuring that the disassembly screw 221 can continue to be screwed into the first threaded hole 111 in subsequent work to apply the pulling force required for disassembling the mold 11.

[0043] Specifically, during the installation process, the operating screw 22 is rotated to drive the disassembly screw 221 to rotate. When the disassembly screw 221 is gradually screwed into the first threaded hole 111, the stop block 21 gradually approaches the direction of the abutment limit block 13. When the stop block 21 contacts the abutment limit block 13, the installation of the disassembly tool 20 is completed.

[0044] See also Figure 6When the disassembly tool 20 is in the working state, the stopper 21 provides an outward pulling force for the mold 11, and the pulling force is used to separate the mold 11 from the mold cavity 10. The pulling force is generated by rotating the operating screw 22. This pulling force acts on the mold 11, loosening the connection between it and the mold cavity 10, and finally achieving effective separation of the mold 11 from the mold cavity 10. This is the key to the entire disassembly process and ensures that the mold 11 can be effectively disassembled.

[0045] Specifically, by continuing to rotate the operating screw 22, the disassembly screw 221 continues to be screwed into the mold 11, and an extrusion limit is generated between the block 21 and the abutment limit block 13. That is, at this time, the position of the block 21 is fixed, the operating screw 22 is in a state of gradually screwing out of the block 21, and the disassembly screw 221 is in a state of gradually screwing into the first threaded hole 111 on the mold 11. In this process, an effective lever system is formed to generate a pulling force, and under the action of the pulling force, it helps the mold 11 overcome the adhesion or friction between it and the mold cavity 10, thereby realizing the separation of the mold 11 and the mold cavity 10. The entire operation process is both efficient and stable, effectively ensuring the integrity and reusability of the mold 11 and the mold cavity 10.

[0046] After the mold 11 is separated from the mold cavity 10 , the disassembly tool 20 can be removed by simply rotating the operating screw 22 in the opposite direction to cancel the abutment between the stopper 21 and the abutment limit block 13 , while the disassembly screw 221 is screwed out of the first threaded hole 111 .

[0047] Furthermore, the diameter of the operating screw 22 is larger than that of the disassembly screw 221. This design provides the operating screw 22 with greater strength and stability when subjected to rotational torque, thereby more effectively transmitting force to the disassembly screw 221, enhancing the durability and work efficiency of the disassembly tool 20. This design also facilitates the quick installation and use of the disassembly tool 20.

[0048] A second threaded hole 211 is formed in the middle of the stopper 21, and the operating screw 22 is mounted on the second threaded hole 211, achieving a stable and adjustable connection between the operating screw 22 and the stopper 21. The thread direction of the operating screw 22 is consistent with that of the second threaded hole 211, so that when the operating screw 22 is rotated, it can be smoothly screwed into or out of the second threaded hole 211, achieving a tight fixation or loosening with the stopper 21. At the same time, the thread direction of the disassembly screw 221 is consistent with that of the first threaded hole 111, ensuring that when the operating screw 22 is rotated, the disassembly screw 221 can be smoothly screwed into or out of the first threaded hole 111 on the mold 11, achieving installation or disassembly of the disassembly tool 20 and effective disassembly of the mold 11. This design improves the reliability and ease of use of the disassembly tool 20, making the disassembly process more stable and efficient.

[0049] Grooves 212 are also provided on both sides of the stop block 21, and the molding machine is provided with guide steps 14 corresponding to the grooves 212. This design makes the positioning of the stop block 21 on the molding machine more precise and stable. The stop block 21 can move along the length direction of the guide steps 14, thereby realizing precise adjustment and control of the disassembly position of the mold 11. This adjustability not only improves the flexibility of the disassembly tool 20, but also ensures the efficiency and safety of the disassembly process.

[0050] The presence of the groove 212 and the guide step 14 provides an additional support surface for the stopper 21, enhances the contact area between it and the molding machine, ensures that the stopper 21 does not shake or deflect during operation, and ensures the smoothness and accuracy of the stopper 21 during installation or removal.

[0051] By moving the stopper 21 , it is possible to ensure that a proper distance is always maintained from the mold 11 during the installation or removal process, thereby improving the adaptability and versatility of the mold 11 removal tool 20 .

[0052] Furthermore, the geometric dimensions of the operating block 23 are larger than the rod diameter of the operating screw 22. This design enables the operating block 23 to have a wider force-bearing surface, thereby increasing the stability and comfort of contact with the operator's hand or tool. During the disassembly process, the operating block 23 serves as the main operating part. Its larger geometric dimensions can effectively disperse the force applied by the hand or tool, reducing fatigue during operation. At the same time, due to the larger size of the operating block 23, it is also easier for the operator to hold and position, thereby improving the accuracy and efficiency of the operation. This design not only enhances the user experience of the mold 11 disassembly tool 20, but also ensures the safety and reliability of the disassembly process. In addition, the surface of the operating block 23 is covered with a rough texture layer, which increases the friction on the surface of the operating block 23, prevents the operating block 23 from slipping during the force application process, and ensures the safety of the operation.

[0053] The thread directions of the operating screw 22 and the second threaded hole 211 are both counterclockwise, and the thread directions of the disassembly screw 221 and the first threaded hole 111 are both clockwise.

[0054] In another embodiment, the thread directions of the operating screw 22 and the second threaded hole 211 are both clockwise, and the thread directions of the disassembly screw 221 and the first threaded hole 111 are both counterclockwise.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
