Description

Technical Field

[0001] This utility model relates to the field of forging die technology, and in particular to a gear shaft forging die that is easy to demold. Background Technology

[0002] A gear shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. The rotating parts in a machine are mounted on the shaft. Forging is a processing method that uses forging machinery to apply pressure to metal blanks, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and dimensions. Forging can improve the material properties of gear shafts. The forging process requires applying enormous pressure to the forging die, and traditional forging dies are prone to wear and breakage under such pressure.

[0003] Existing technology CN204148427U discloses a forging die, including an inner ring and an outer ring. The center of the inner ring is a forging cavity, and the outer ring is fitted over the inner ring with an interference fit. The advantages of this invention are: by using a combination of inner and outer rings and employing two different materials, a high-hardness material is selected for the inner ring to provide wear resistance, while a high-toughness material is used for the outer ring. The interference fit encloses the inner ring, preventing it from cracking, thus achieving both wear resistance and toughness. This extends the service life of the forging die and solves the problem of traditional forging dies being prone to cracking due to excessive hardness and prone to wear due to insufficient hardness.

[0004] For existing forging dies, the difficulty in demolding existing gear shaft forging dies reduces production efficiency. Utility Model Content

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The first embodiment of this application is as follows:

[0019] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the easy-to-demold gear shaft forging mold according to the first embodiment of this utility model. Figure 2 This is a structural schematic diagram of the ejector component according to the first embodiment of this utility model. Figure 3 This is a schematic diagram of the overall structure of the easy-to-demold gear shaft forging mold according to the second embodiment of this utility model.

[0020] This utility model discloses an easy-to-demold gear shaft forging mold, comprising a base 101, a mold body 102, a support base 103, a sliding plate 104, an ejector rod 105, an ejector block 106, a mounting bracket 107, an ejector cylinder 108, a support plate 109, a drive cylinder 110, and a process groove 111. It solves the problem of reduced production efficiency caused by the difficulty in demolding existing gear shaft forging molds. It is understood that the aforementioned solution can also be used to reduce the possibility of mold or product damage.

[0021] In this embodiment, the base 101 is a rectangular body, which plays a role in stable support. The forging chamber of the mold body 102 extends through the mold body 102, which facilitates the demolding of the gear shaft. This solves the problem that existing gear shaft forging molds have difficulty in demolding, thus reducing production efficiency.

[0022] The support base 103 is fixedly connected to the base 101 and located on top of the base 101. The mold body 102 is fixedly mounted on the support base 103. The slide plate 104 is slidably connected to the support base 103 and located on the side of the support base 103 near the mold body 102. The ejector rod 105 passes through the slide plate 104 and is slidably connected to the slide plate 104. The ejector block 106 is fixedly connected to the ejector rod 105 and located at the end of the ejector rod 105 near the mold body 102. The ejection component drives the ejector block 106. 6. Lifting / lowering mechanism: The driving component drives the sliding plate 104 to move. The support base 103 is rectangular with a rectangular slot at the top. The mold body 102 is fixed to the top of the support base 103 by bolts and is located above the rectangular slot. The sliding plate 104 is rectangular and slidably installed in the rectangular slot. The top surface of the sliding plate 104 is on the same plane as the bottom surface of the mold body 102. The sliding plate 104 can seal the bottom opening of the mold body 102. A circular through hole is provided on the right side of the sliding plate 104. The push rod 105 is a smooth cylinder. The diameter matches the diameter of the circular through hole. The push rod 105 passes through the circular through hole and is slidably connected to the slide plate 104. The push block 106 is circular and is connected to the top end of the push rod 105, allowing the push block 106 to move with the push rod 105. The push block 106 is used to push the gear shaft. When the left side of the slide plate 104 is below the mold body 102, it can seal the bottom opening of the mold body 102, facilitating the forging of the gear shaft. When the right side of the slide plate 104 is below the mold body 102, the bottom opening of the mold body 102 can be sealed, facilitating the forging of the gear shaft. The top block 106 can push the gear shaft inside the mold body 102. The ejector component is installed at the bottom of the slide plate 104 and is used to drive the top rod 105 to rise and fall. The driving component is used to drive the slide plate 104 to move. The movement of the slide plate 104 drives the top block 106 to move below the mold body 102. With the action of the ejector component, the top block 106 pushes out the gear shaft, realizing convenient demolding. This solves the problem that existing gear shaft forging molds have difficulty in demolding, which reduces production efficiency.

[0023] Secondly, the mounting bracket 107 is fixedly connected to the slide plate 104 and is located on the side of the slide plate 104 near the top rod 105; the ejector cylinder 108 is fixedly mounted on the mounting bracket 107, and the output end of the ejector cylinder 108 is fixedly connected to the top rod 105. The mounting bracket 107 is U-shaped and fixedly mounted on the bottom of the slide plate 104 with the opening facing upwards, located below the top rod 105. The ejector cylinder 108 is vertically mounted in the mounting bracket 107 by bolts, so that the ejector cylinder 108 can move synchronously with the slide plate 104. Through the extension and retraction of the ejector cylinder 108, the top rod 105 drives the top block 106 to rise and fall.

[0024] Meanwhile, the support plate 109 is fixedly connected to the base 101 and is located on the side of the base 101 near the slide plate 104; the drive cylinder 110 is fixedly installed on the support plate 109, and the output end of the drive cylinder 110 is fixedly connected to the slide plate 104. The support plate 109 provides support and installation conditions for the drive cylinder 110. The drive cylinder 110 is horizontally installed on the support plate 109, and its output end is fixedly connected to the side of the slide plate 104. By extending and retracting the drive cylinder 110, the slide plate 104 is moved.

[0025] In addition, the process groove 111 is located on the side of the slide plate 104 near the top block 106. The process groove 111 is located on the top of the slide plate 104, corresponding to the position of the top block 106, and its diameter is slightly larger than that of the top block 106. Through the process groove 111, the top block 106 can be stored in the process groove 111, thereby avoiding affecting the movement of the slide plate 104.

[0026] In this embodiment, during forging, the drive cylinder 110 is in a retracted state, and the left side of the slide plate 104 is located below the mold body 102, blocking the bottom opening of the mold body 102. When demolding is required after forging, the drive cylinder 110 is activated, and its output end extends, driving the slide plate 104 to move to the left, so that the right side of the slide plate 104 is located below the mold body 102. At this time, the top block 106 is located at the bottom opening of the mold body 102. The ejector cylinder 108 is activated, and its output end extends, causing the ejector rod 105 to push the top block 106 upward. The top block 106 extends into the mold body 102 to eject the gear shaft, thereby achieving demolding of the gear shaft. This solves the problem of reduced production efficiency caused by the difficulty in demolding existing gear shaft forging molds.

[0027] The second embodiment of this application is as follows:

[0028] Please see Figure 3 , Figure 3 This is a schematic diagram of the overall structure of the easy-to-demold gear shaft forging mold according to the second embodiment of the present invention. Based on the first embodiment, the easy-to-demold gear shaft forging mold of this embodiment further includes a sliding groove 201 and a protrusion 202.

[0029] In this embodiment, the support base 103 has a sliding groove 201, and the slide plate 104 has a protrusion 202. The aforementioned solution enables the slide plate 104 to slide with the support base 103.

[0030] The sliding groove 201 is located on the side of the support base 103 near the slide plate 104; the protrusion 202 cooperates with the sliding groove 201. The sliding groove 201 is located on the inner wall of the rectangular slot of the support base 103, extending from one side of the support base 103 to the other side. The protrusion 202 is located on both sides of the slide plate 104. The sliding connection between the slide plate 104 and the support base 103 is realized through the cooperation between the protrusion 202 and the sliding groove 201.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
