Description

Technical Field

[0001] The utility model relates to the technical field of mold ejection structures, in particular to a mold ejection structure of an injection molding machine. Background Art

[0002] The injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. In the injection molding process, the injection mold is the key device to form the product. After the plastic is finalized, the product needs to be taken out of the mold. Patent No. CN202221042898.5 discloses an ejection structure of an injection mold for an injection molding machine. Through the ejection demoulding mechanism, the forming structure in the mold can be automatically protruded by an electric rod during use, without manual operation, and the demoulding process is faster, which improves production efficiency to a certain extent. However, since the push block used for material removal inside the mold is fixedly installed on the top of the push shaft, and the push block will have greater friction due to material removal, causing its surface to be easily worn. When the wear is too large, it needs to be disassembled and replaced, and the fixed push block is quite inconvenient to disassemble and assemble. To this end, we propose a mold ejection structure for an injection molding machine. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a mold ejection structure of an injection molding machine.

[0004] The technical solution adopted by the utility model to solve the technical problem is a mold ejection structure of an injection molding machine, comprising a machine table, a mold body for injection molding is mounted on the top surface of the machine table, and a top plate for material removal is fitted on the inner side of the mold body, a vertical rod located on the inner side of the machine table is clamped on the outer side end surface of the top plate, and a disk sleeve slidably connected to the vertical rod is mounted on the inner side of the machine table through bolts;

[0005] The outer circumference of the vertical rod is provided with an external thread for adjustment, and the outer circumference of the vertical rod is equipped with a ring seat threadedly connected to the external thread, a spring for buffering is installed between the ring seat and the disk sleeve, the end of the vertical rod away from the top plate is clamped with a convex rod for connection, and the end of the convex rod away from the vertical rod is integrally constructed with a bottom plate for connection.

[0006] By adopting the above technical solution, when the mold body is used for injection molding, the vertical rod can be fixed and convenient to push the top plate located inside the mold body, so that the top plate can eject the object formed inside the mold body. At the same time, when the top plate is worn, the vertical rod and the top plate can be separated from each other, and the top plate can be disassembled and replaced separately, so that the top plate can continue to stably remove the material inside the mold, and the disassembly and assembly are simple and convenient;

[0007] When the vertical rod moves, the spring can be squeezed by the ring seat screwed with the external thread on the outer periphery of the vertical rod, so that the spring can provide a certain buffer force for the vertical rod. At the same time, when the vertical rod is not pressurized by external force, the spring can push the ring seat back and drive the vertical rod to return, so that the top plate can return, which is convenient for the mold body to continue the injection molding work. At the same time, the bottom plate and the convex rod at one end of the vertical rod away from the top plate are convenient for disassembly and assembly, and are convenient for disassembly and replacement when the vertical rod is worn. At the same time, since the vertical rod and the disc sleeve are inserted into and slided with each other, and the disc seat is conveniently installed on the inner side of the machine with bolts, it is convenient to limit the movement of the vertical rod, and to reduce the situation of random shaking of the vertical rod when moving.

[0008] Specifically, a hydraulic rod bolted to the chassis is assembled on the inner side of the machine platform.

[0009] By adopting the above technical solution, the power output end of the hydraulic rod is conveniently connected to the chassis through bolts, which is convenient for providing thrust to the chassis and the top plate, and is convenient for removing materials from the mold body.

[0010] Specifically, the outer peripheral surface of the top plate, the outer peripheral surface of the vertical rod and the outer peripheral surface of the ring seat are all threadedly installed with a rotating rod that can be used for fixing.

[0011] By adopting the above technical solution, multiple sets of rotating rods are respectively screwed and installed on the outer circumference of the top plate, the vertical rod and the ring seat, so that after the top plate and the vertical rod are connected, the vertical rod and the convex rod are connected, and the position of the ring seat and the external thread is fixed after being screwed together, so that after the top plate, the vertical rod, the convex rod and the ring seat are connected, they can operate stably and are convenient for disassembly and assembly.

[0012] Specifically, the inner circumferential surface of the top plate and the side where the vertical rod and the convex rod are in contact are integrally constructed with an arc strip that can be used for connection, and the end of the vertical rod located on the inner side of the plate sleeve and the outer circumferential surface of the convex rod are both provided with an arc groove that fits and connects with the arc strip.

[0013] By adopting the above technical solution, the arc groove and the arc strip are connected in a fitting manner, which is convenient for improving the stability after the top plate and the vertical rod are connected, and after the convex rod and the vertical rod are connected, so that there will be no self-rotation after the three are connected.

[0014] Specifically, a rubber ring for protection is bonded to a side of the ring seat close to the spring.

[0015] By adopting the above technical solution, the rubber ring has a certain spring, which is convenient for reducing the situation where the ring seat squeezes the spring so that friction between the spring and the ring seat occurs when the spring contracts and causes scratches.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application, through the design of the mold body, the top plate and the vertical rod, can make the vertical rod firmly and conveniently push the top plate located inside the mold body when the mold body is used for injection molding, so that the top plate can eject the object formed inside the mold body. At the same time, when the top plate is worn, the top plate can be disassembled and replaced separately by simply separating the vertical rod and the top plate, so that the top plate can continue to stably remove materials inside the mold, and the disassembly and assembly are simple and convenient.

[0018] 2. The design of the disk sleeve, external thread, ring seat, spring, protruding rod and chassis in the technical solution of the present application makes it possible to squeeze the spring through the ring seat which is threadedly connected to the external thread on the outer periphery of the vertical rod when the vertical rod moves, so that the spring can provide a certain buffering force for the vertical rod. At the same time, when the vertical rod is not pressurized by external force, the spring can push the ring seat back and drive the vertical rod to return, so that the top plate can return, which is convenient for the mold body to continue the injection molding work. At the same time, the chassis and protruding rod at one end of the vertical rod away from the top plate are convenient for disassembly and assembly, and are convenient for disassembly and replacement when the vertical rod is worn. At the same time, since the vertical rod and the disk sleeve are mutually inserted and slidable, and the disk seat is conveniently installed on the inner side of the machine with bolts, it is convenient to limit the movement of the vertical rod, and to reduce the situation where the vertical rod shakes randomly when moving.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figure 1-3The embodiment of the utility model provides a technical solution: a mold ejection structure of an injection molding machine, comprising a machine table 1, a mold body 2 for injection molding is mounted on the top surface of the machine table 1, and a top plate 3 for material removal is fitted on the inner side of the mold body 2, a vertical rod 4 located on the inner side of the machine table 1 is clamped on the outer side end surface of the top plate 3, and a disk sleeve 5 slidably connected to the vertical rod 4 is mounted on the inner side of the machine table 1 through bolts; an external thread 6 for adjustment is provided on the outer periphery of the vertical rod 4, and a ring seat 7 threadedly connected to the external thread 6 is mounted on the outer periphery of the vertical rod 4, a spring 8 for buffering is mounted between the ring seat 7 and the disk sleeve 5, an end of the vertical rod 4 away from the top plate 3 is clamped with a convex rod 9 for connection, and an end of the convex rod 9 away from the vertical rod 4 is integrally constructed with a bottom plate 10 for connection.

[0026] When in use, when the mold body 2 is used for injection molding, the vertical rod 4 can be made to push the top plate 3 located inside the mold body 2 in a certain and convenient manner, so that the top plate 3 can eject the object formed inside the mold body 2. At the same time, when the top plate 3 is worn, the vertical rod 4 and the top plate 3 can be separated from each other, and the top plate 3 can be disassembled and replaced separately, so that the top plate 3 can continue to stably remove the material inside the mold, and the disassembly and assembly are simple and convenient;

[0027] When the vertical rod 4 moves, the ring seat 7 that is threadedly connected to the external thread 6 on the outer periphery of the vertical rod 4 can be used to squeeze the spring 8, so that the spring 8 can provide a certain buffer force for the vertical rod 4. At the same time, when the vertical rod 4 is not pressurized by external force, the spring 8 can easily push the ring seat 7 back and drive the vertical rod 4 to return, so that the top plate 3 can return, which is convenient for the mold body 2 to continue the injection molding work. At the same time, the bottom plate 10 and the protruding rod 9 at one end of the vertical rod 4 away from the top plate 3 are convenient for disassembly and assembly, and are convenient for disassembly and replacement when the vertical rod 4 is worn. At the same time, since the vertical rod 4 and the disc sleeve 5 are inserted into each other and slide, and the disc seat is conveniently installed on the inner side of the machine 1 with bolts, it is convenient to limit the movement of the vertical rod 4, and to reduce the situation where the vertical rod 4 shakes randomly when moving.

[0028] like Figure 2 As shown, a hydraulic rod 11 is assembled on the inner side of the machine platform 1 and is bolted to the chassis 10 via bolts.

[0029] When in use, the power output end of the hydraulic rod 11 is conveniently connected to the chassis 10 through bolts, so as to provide thrust to the chassis 10 and the top plate 3, so as to facilitate the material removal work inside the mold body 2.

[0030] like Figure 2 and Figure 3 As shown, the outer peripheral surface of the top plate 3, the outer peripheral surface of the vertical rod 4 and the outer peripheral surface of the ring seat 7 are all screwed and installed with a rotating rod 12 that can be used for fixing.

[0031] When in use, multiple sets of rotating rods 12 are respectively screwed and installed on the outer periphery of the top plate 3, the vertical rod 4 and the ring seat 7, so as to fix the position of the ring seat 7 and the external thread 6 after the top plate 3 is connected to the vertical rod 4, the vertical rod 4 is connected to the convex rod 9, and the ring seat 7 is screwed together. After the top plate 3, the vertical rod 4, the convex rod 9 and the ring seat 7 are connected, they can operate stably and are convenient for disassembly and assembly.

[0034] like Figure 2 and Figure 3 As shown, a rubber ring 13 for protection is bonded to one side of the ring seat 7 close to the spring 8 .

[0035] When in use, the rubber ring 13 has a certain amount of spring 8, which is convenient for reducing the situation where the ring seat 7 squeezes the spring 8 so that when the spring 8 contracts, friction occurs between the ring seat 7 and the ring seat 7, causing scratches.

[0036] The working principle and use process of the utility model are as follows: when in use, first install the corresponding structural components in the appropriate position, and when the mold body 2 is used for injection molding, the vertical rod 4 can be made to push the top plate 3 located on the inner side of the mold body 2 in a certain and convenient manner, so that the top plate 3 can eject the object formed on the inner side of the mold body 2. At the same time, when the top plate 3 is worn, it is only necessary to unscrew the rotating rod 12 between the vertical rod 4 and the top plate 3 to separate the vertical rod 4 and the top plate 3. The top plate 3 can be disassembled and replaced separately, so that the top plate 3 can continue to stably remove the material inside the mold, and the disassembly and assembly are simple and convenient. When the vertical rod 4 moves, it can be conveniently removed by the vertical rod 4. The ring seat 7, which is threadedly connected to the external thread 6 on the outer periphery, squeezes the spring 8, so that the spring 8 can provide a certain buffer force for the vertical rod 4. At the same time, when the vertical rod 4 is not pressurized by external force, the spring 8 can easily push the ring seat 7 back and drive the vertical rod 4 to return, so that the top plate 3 can return, which is convenient for the mold body 2 to continue the injection molding work. At the same time, the bottom plate 10 and the protruding rod 9 at one end of the vertical rod 4 away from the top plate 3 are convenient for disassembly and assembly, and are convenient for disassembly and replacement when the vertical rod 4 is worn. At the same time, since the vertical rod 4 and the disc sleeve 5 are mutually inserted and slidable, and the disc seat is conveniently installed on the inner side of the machine platform 1 with bolts, it is convenient to limit the movement of the vertical rod 4 and to reduce the situation where the vertical rod 4 shakes randomly when moving.
