Description

Technical Field

[0001] This utility model relates to the field of mold insert technology, and in particular to a detachable mold insert structure. Background Technology

[0002] Inserts are replaceable modules in injection molds, typically used in the forming part of the mold. In mold manufacturing, mold inserts are used to fix the position of the mold, ensuring the accuracy and stability of the product's position during processing, and playing a role in positioning and support.

[0003] For example, CN216501864U discloses a mold insert assembly, including a pressure plate, pressure rods on both sides below the pressure plate, a rotating shaft connected through the pressure rods, an insert fixedly connected to one end of the rotating shaft, several stamping dies on the insert, the other end of the rotating shaft embedded in the positioning rod, a slider at one end of the positioning rod, the slider embedded in the guard plate, a partition fixedly connected to the bottom of the guard plate, a pressure spring on one side above the partition, and the top of the pressure spring fixedly connected to the positioning rod.

[0004] However, in the existing technology, since the insert is used to fix the mold blank, it needs to be firmly installed on the table when fixing. However, this method makes it difficult to disassemble the insert. In actual operation, the difficulty of disassembly can be reduced by reducing the firmness. However, reducing the firmness will affect the stability of the insert, and it is easy to wobble when using the mold blank. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the inserts in the prior art are difficult to disassemble. In actual operation, the difficulty of disassembly can be reduced by decreasing the firmness, but reducing the firmness will affect the stability of the insert. Therefore, a detachable mold insert structure is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a detachable mold insert structure, comprising an insert plate, a connecting plate fixedly connected to the bottom of the insert plate, a screw threadedly connected to the inside of the connecting plate, a positioning plate threadedly connected to one end of the screw, a threaded hole provided at the junction of the positioning plate and the screw, a filling block slidably connected to the lower surface of the positioning plate, the filling block being located on both sides of the connecting plate, a trapezoidal block fixedly installed on the lower surface of the connecting plate, and limit blocks fixedly installed at both ends of the positioning plate, with the filling block located between the trapezoidal block and the limit block.

[0007] Preferably, the trapezoidal block and the filling block are slidably connected, and a limiting groove is provided at the junction of the filling block and the trapezoidal block.

[0008] Preferably, the shape of the connecting plate is adapted to the shape of the limiting groove.

[0009] Preferably, one end of the limiting block is fixedly connected to a limiting protrusion, and the filling block is slidably connected to the limiting protrusion.

[0010] Preferably, a trapezoidal groove is provided at the junction of the filling block and the limiting protrusion.

[0011] Preferably, vertical plates are fixedly installed on both sides of the two filling blocks, and a guide rod is fixedly connected to one side of one of the vertical plates.

[0012] Preferably, the other end of the guide rod passes through another vertical plate, one of which is fixedly connected to a tension spring on one side.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the position of the connecting plate is determined by setting a filling block and a limiting block. During installation, the screw can ensure the stability of the connecting plate, allowing the top plate to be stably in contact with the mold blank. This structure can ensure the stability of the mold blank. When disassembly is required later, the trapezoidal block can be pushed out by the return of the filling block after the screw is removed. This method can ensure the stability of the plate while having the function of quick disassembly.

[0015] 2. In this utility model, the movement path of the filling block is determined by setting a limiting protrusion. The limiting block can determine the movement range of the filling block, thereby ensuring the structural stability during disassembly. Furthermore, the two filling blocks are connected by a guide rod and a tension spring, which can ensure that the filling block can be pushed open normally and subsequently reset.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a detachable mold insert structure, including an insert plate 2, a connecting plate 3 fixedly connected to the bottom of the insert plate 2, a screw 4 threadedly connected to the inside of the connecting plate 3, a positioning plate 1 threadedly connected to one end of the screw 4, a threaded hole 8 opened at the junction of the positioning plate 1 and the screw 4, a filling block 5 slidably connected to the lower surface of the positioning plate 1, the filling block 5 being located on both sides of the connecting plate 3, a trapezoidal block 14 fixedly installed on the lower surface of the connecting plate 3, and limit blocks 6 fixedly installed at both ends of the positioning plate 1, with the filling block 5 located between the trapezoidal block 14 and the limit block 6;

[0024] The trapezoidal block 14 and the filling block 5 are slidably connected. A limiting groove 7 is provided at the junction of the filling block 5 and the trapezoidal block 14. The shape of the connecting plate 3 is adapted to the shape of the limiting groove 7.

[0025] The specific settings and functions of this embodiment are described below. The inlay plate 2 is connected to the connecting plate 3. When installing the inlay plate 2, the trapezoidal block 14 on the lower surface of the connecting plate 3 is inserted between the two filling blocks 5. The filling block 5 is specifically a trapezoidal structure, and a limiting groove 7 for docking the trapezoidal block 14 is provided on its inclined surface. Since the contact surface between the trapezoidal block 14 and the filling block 5 is also inclined, during its movement, it will push the filling block 5 to move towards the limiting block 6, so that the two filling blocks 5 are separated by a sufficient distance so that the trapezoidal block 14 fits together with the positioning plate 1.

[0026] After the trapezoidal block 14 is attached to the positioning plate 1, the positioning plate 1 and the trapezoidal block 14 are connected together by the screw 4. Due to the presence of the limiting block 6, the movement range of the filling block 5 is restricted. When the filling block 5 moves, when one filling block 5 contacts the limiting block 6, only the other filling block 5 that does not contact the limiting block 6 can move. This ensures that the screw 4 can be aligned with the threaded hole 8, thereby ensuring the connection stability between the trapezoidal block 14 and the positioning plate 1. The corner of the insert 2 is provided with a positioning hole for connecting the mold blank.

[0027] Example 2: Figure 3 and Figure 4 As shown, a limiting protrusion 12 is fixedly connected to one end of the limiting block 6, and the filling block 5 is slidably connected to the limiting protrusion 12. A trapezoidal groove 13 is provided at the junction of the filling block 5 and the limiting protrusion 12. Vertical plates 9 are fixedly installed on both sides of the two filling blocks 5. A guide rod 10 is fixedly connected to one side of one of the vertical plates 9, and the other end of the guide rod 10 passes through the other vertical plate 9. A tension spring 11 is fixedly connected to one side of one of the vertical plates 9.

[0028] The overall effect of this embodiment is that the filling block 5 is slidably connected to the limiting protrusion 12 through the trapezoidal groove 13, and the trapezoidal block 14 pushes the filling block 5 to move along the direction of the limiting protrusion 12. During this process, the filling block 5 will stretch the tension spring 11. The tension spring 11 is adjusted on the guide rod 10. By determining the position of the tension spring 11, it is ensured that the spring will not be affected by the outside world.

[0029] When disassembling panel 2, screw 4 is removed from connecting plate 3. At this time, trapezoidal block 14 loses the fixation of screw 4 and can no longer press the filling block 5. At this time, tension spring 11 begins to rebound, bringing the two filling blocks 5 closer to each other, thereby achieving the purpose of pushing out trapezoidal block 14, thus reducing the difficulty of disassembly. Guide rod 10 and tension spring 11 are installed on vertical plate 9 on the side of filling block 5, which will not affect the docking of trapezoidal block 14 and positioning plate 1.

[0030] The usage method and working principle of this device: The corner of the insert 2 is provided with a positioning hole for connecting the mold blank. When installing the insert 2, the trapezoidal block 14 on the lower surface of the connecting plate 3 is inserted between the two filling blocks 5. The trapezoidal block 14 contacts the limiting groove 7, and in the subsequent movement process, it pushes the filling block 5 to move towards the limiting block 6, so that the two filling blocks 5 are separated by a sufficient distance so that the trapezoidal block 14 fits with the positioning plate 1.

[0031] As the filling block 5 moves along the limiting protrusion 12, the filling block 5 will stretch the tension spring 11. When one filling block 5 contacts the limiting block 6, only the other filling block 5 that does not contact the limiting block 6 can move, so that the screw 4 is aligned with the threaded hole 8. Then the screw 4 is used to connect the positioning plate 1 and the trapezoidal block 14 together to complete the installation of the panel 2.

[0032] When disassembling panel 2, screw 4 is removed from connecting plate 3. At this time, trapezoidal block 14 loses the fixation of screw 4 and can no longer press the filling block 5. Tension spring 11 begins to rebound, pulling the two filling blocks 5 closer to each other and pushing trapezoidal block 14 out from the two filling blocks 5, thus completing the disassembly of panel 2.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
