Description

Technical Field

[0001] The utility model relates to the technical field of fixture devices for mold welding, in particular to a mold welding fixture. Background Art

[0002] A mold is a tool used to make molded objects. This tool is composed of various parts and can achieve the processing of the object's shape by changing the physical state of the molded material. It is an indispensable and important tool in industrial production. In the mold production process, mold welding is a key step in welding and assembling the various parts of the mold to form a complete mold structure. Mold welding is also an indispensable and important process link in mold manufacturing and maintenance.

[0003] During the mold welding process, mold welding fixtures are usually required to clamp and fix the mold components. They not only ensure the position accuracy and shape accuracy of the mold components during the welding process, but also take into account the convenience of the operator, making the clamping and loosening operations simple and quick. Therefore, mold welding fixtures play a vital role in the mold manufacturing and maintenance process. By selecting the appropriate fixture type and structure and performing regular maintenance and care, the quality and efficiency of mold welding can be ensured.

[0004] Currently, when welding molds, a set of clamps is usually used to clamp the two molds to be welded respectively, and then the molds to be welded are brought closer together until their adjacent ends are tightly fitted together, thereby completing the welding of the molds.

[0005] However, when welding a hollow mold, the fixture directly clamps the outer surface of the mold, which makes the contact area between the mold and the fixture larger, making it easy for the mold to be affected by various forces generated during the welding process, thereby affecting the service life of the mold. Utility Model Content

[0006] Based on this, the purpose of the present utility model is to provide a mold welding fixture to solve the technical problem that when welding a hollow mold, the fixture directly clamps the outer surface of the mold, so the local temperature of the mold will rise during the welding process, causing the outer surface fixture to be directly affected by thermal stress, thereby causing the fixture to deform and affecting the use of the device.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold welding fixture, comprising a column, a fixed rod passing through both sides of the column, the surface of the fixed rod is rotatably connected to a group of threaded rods, the outer surface of each threaded rod is threadedly connected to a movable block, the outer surface of the fixed rod is fixedly connected to a group of connecting blocks, the outer surface of each connecting block is rotatably connected to one end of several first connecting rods, the outer surface of each movable block is rotatably connected to one end of several second connecting rods, the other end of each first connecting rod and the corresponding second connecting rod are rotatably connected to the bottom of the corresponding fixed block, each first connecting rod and the corresponding second connecting rod are rotatably connected by an axis, the top of each fixed block is slidably connected to a clamping block, each fixed block and the corresponding clamping block are connected by several springs, and a damper is provided in each spring.

[0008] By adopting the above technical solution, one of the molds can be placed between the threaded rod and the connecting block near the side of the column, and the end of the mold to be welded is flush with the connecting block. Then, the threaded rod is driven to rotate to adjust the position of the movable block on its outer surface. The corresponding connecting block can be pushed to move by the first connecting rod and the second connecting rod between the connecting block and the corresponding movable block, so that the clamping block contacts the inner wall of the mold. Since the fixed block and the clamping block are connected by a spring, different extrusions can be generated on the clamping blocks at different positions through the inner wall of the mold, driving them to move downward, thereby completing the clamping of the mold with an irregular inner wall. Then, another mold to be welded is placed between the other threaded rod and the connecting block, so that it is fitted together with one end of the other mold. Then, the other threaded rod is driven to rotate to fix its position. At this time, the adjacent ends of the two molds with welding are fitted together, and the welding of the mold can be completed. This structure clamps and fixes it from the inner wall of the mold, so it can protect the structure to a certain extent and reduce the contact area with the mold, thereby reducing the influence of various factors on the clamp during welding, thereby extending the service life of the clamping structure.

[0009] The utility model is further configured such that one end of one of the threaded rods is fixedly connected to a first turntable, one of the threaded rods and the first turntable rotate on the outer surface of the fixed rod, a connecting rod is movably passed through the fixed rod, one end of the connecting rod is fixedly connected to a second turntable, the other end of the connecting rod is fixedly connected to one end of another threaded rod, and the other threaded rod rotates on one end of the connecting rod.

[0010] By adopting the above technical solution, one of the threaded rods can be driven by the first turntable to rotate forward and backward, thereby adjusting the position of the movable block corresponding to the outer surface of the threaded rod. At the same time, the other threaded rod can be driven by the second turntable and the connecting rod to rotate, thereby adjusting the position of the movable block corresponding to its outer surface. Therefore, the mold can be better clamped and welded.

[0011] The utility model is further configured such that a plurality of sliding blocks are slidably connected in each of the fixed blocks, and each top-layer sliding block is fixedly connected to the bottom of the clamping block.

[0012] By adopting the above technical solution, a smooth moving path can be provided for the clamping block, so as to better clamp the mold firmly. At the same time, the clamping block can slide in the fixed block according to the actual shape and size, so that it can fit closely to the surface of the clamped object, thereby improving the stability of the clamping.

[0013] The present invention is further configured such that the first turntable and the second turntable are respectively located on both sides of the column, and a second rubber layer is respectively provided on the side of the first turntable and the second turntable in contact with the column.

[0014] By adopting the above technical solution, the friction between the first turntable and the column and the friction between the second turntable and the column can be increased by the second rubber layer, so that when the external force is small, they cannot be driven to rotate, thereby avoiding affecting the use of the device. At the same time, a protective layer can be formed by the second rubber layer, which helps to extend the service life of the first turntable, the second turntable and the column.

[0015] The present invention is further configured such that the bottom of the column is fixedly connected to a base, the bottom of the base is fixedly connected to a plurality of protrusions, and positioning holes are provided at the four corners of the base.

[0016] By adopting the above technical solution, the setting of the protrusion can increase the area of ​​the base and the contact surface, thereby enhancing the stability of the entire structure. At the same time, fixed connectors such as bolts can be installed in the positioning holes, which can simplify the installation process and improve installation efficiency.

[0017] The utility model is further configured such that a first rubber layer is provided on the top of each clamping block.

[0018] By adopting the above technical solution, the friction between each clamping block and the contact surface of the mold can be increased, thereby ensuring that the mold can be firmly clamped and is not prone to sliding or falling off. At the same time, the first rubber layer can protect the mold and avoid damage to the mold.

[0019] The present invention is further configured such that each of the sliders is provided with a "T"-shaped structure.

[0020] By adopting the above technical solution, the sliding stability of each layer of slider can be increased. At the same time, the sliding range of the slider can be limited so that it slides within the specified space, preventing it from sliding out of the fixed block, thereby affecting the use of the device.

[0021] In summary, the present invention has the following beneficial effects:

[0022] The utility model places the mold between the corresponding movable block and the connecting block, and then adjusts the position of the movable block, so that the fixed block can be pushed to move by the first connecting rod and the second connecting rod. Since the fixed block and the clamping block are connected by a spring, different extrusions can be generated on the clamping blocks in different positions through the inner wall of the mold, so that the mold with irregular inner wall can be clamped by the fixed block and the clamping block. This structure clamps and fixes the mold from the inner wall, so it can protect the structure to a certain extent, and reduce the contact area with the mold, which can reduce the influence of various factors on the clamp during welding, and facilitate extending the service life of the clamping structure.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] A mold welding fixture, such as Figure 1-4As shown, it includes a column 1, a base 17 is fixedly connected to the bottom of the column 1, and a plurality of protrusions 19 are fixedly connected to the bottom of the base 17, which can increase the area of ​​the base 17 and the contact surface, thereby enhancing the stability of the entire structure, and positioning holes 18 are provided at the four corners of the base 17, so fixing parts such as bolts can be installed in the positioning holes 18, which facilitates the rapid installation of the device, thereby improving the installation efficiency.

[0031] Then, a fixed rod 2 is passed through both sides of the column 1, and the surface of the fixed rod 2 is rotatably connected to a group of threaded rods 3, and the outer surface of each threaded rod 3 is threadedly connected to a movable block 12, which can be driven to move the position of the corresponding movable block 12 by rotating the threaded rod 3, and the outer surface of the fixed rod 2 is fixedly connected to a group of connecting blocks 4, and the outer surface of each connecting block 4 is rotatably connected to one end of several first connecting rods 5, and the outer surface of each movable block 12 is rotatably connected to one end of several second connecting rods 6, and the other end of each first connecting rod 5 and the corresponding second connecting rod 6 are rotatably connected to the bottom of the corresponding fixed block 7, and each first connecting rod 5 and the corresponding second connecting rod 6 are rotatably connected by an axis, then the first connecting rod 5 and the second connecting rod 6 can be driven to rotate by the movement of the movable block 12, thereby pushing the fixed block 7 to move, so as to better treat the welding mold. For clamping, a clamping block 20 is slidably connected to the top of each fixed block 7, and each fixed block 7 is connected to the corresponding clamping block 20 by a number of springs 10. A damper 11 is provided in each spring 10. Therefore, after the corresponding clamping block 20 is driven to move the same distance by the fixed block 7, the clamping block 20 can be squeezed by the irregular surface of the inner wall of the mold, so that the clamping blocks 20 at different positions squeeze the corresponding springs 10, so that the clamping block 20 can move downward by different distances, and the clamping block 20 is close to the inner wall of the mold, thereby fixing the position of the mold to be welded, and clamping can be achieved from the inner wall of the mold to be welded, reducing the contact area between the fixture and the mold, and can also protect the clamping structure through the mold to a certain extent, so it can reduce the influence of various factors on the clamping structure during welding, and facilitate extending the service life of the clamping structure.

[0032] A plurality of sliders 8 are slidably connected in each fixed block 7, and each slider 8 is set to a "T"-shaped structure, which can increase the sliding stability of the slider 8 and limit the movement range of the slider 8. Each top slider 8 is fixedly connected to the bottom of the clamping block 20, so that the position of the clamping block 20 can be adjusted. A first rubber layer 9 is provided on the top of each clamping block 20, which can increase the friction between each clamping block 20 and the mold contact surface, thereby ensuring that the mold can be firmly clamped and is not prone to sliding or falling off.

[0033] Furthermore, a first turntable 13 is fixedly connected to one end of one of the threaded rods 3, and one of the threaded rods 3 and the first turntable 13 rotate on the outer surface of the fixed rod 2. The first turntable 13 can drive the corresponding one of the threaded rods 3 to rotate on the outer surface of the fixed rod 2, thereby adjusting the position of the corresponding movable block 12. At the same time, a connecting rod 14 is movable through the fixed rod 2, and one end of the connecting rod 14 is fixedly connected to the second turntable 15. The other end of the connecting rod 14 is fixedly connected to one end of the other threaded rod 3. The other threaded rod 3 rotates at one end of the connecting rod 14. The second turntable 15 and the connecting rod 14 can drive the other threaded rod 3 to rotate at one end of the fixed rod 2, thereby adjusting the position of the corresponding movable block 12, and the inner wall of the mold to be welded can be clamped and fixed, affecting the influence on the clamping structure during the welding process.

[0034] At the same time, the first turntable 13 and the second turntable 15 are respectively located on both sides of the column 1, so that the first turntable 13 and the second turntable 15 do not affect each other. In addition, the first turntable 13 and the second turntable 15 are respectively provided with a second rubber layer 16 on the side in contact with the column 1, thereby increasing the friction between the first turntable 13 and the column 1 and the second turntable 15 and the column 1. Therefore, when the external force is small, they cannot be driven to rotate, thereby avoiding affecting the use of the device.
