Description

Technical Field

[0002] With the development of technology, casting and forging dies are gradually being applied to the molding and manufacturing of larger products. Casting and forging dies form products through the cavity between the rear die and the front die, and further forge the products.

[0003] In the prior art, the rear mold is located behind the front mold and moves to the front mold along the axis of the guide post. At this time, the rear mold fits against the front mold and is in the initial mold-closing state. When the product needs to be forged, the first forging rod passing through the rear mold acts on the product in the cavity between the rear mold and the front mold with a large forging force. The forging force easily separates the rear mold and the front mold, resulting in a gap between the rear mold and the front mold. The product between the rear mold and the front mold has a poor forging effect after casting, and the forged product does not reach the required density. Summary of the Invention

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] The purpose of this invention is to provide a forming machine for use in a locking and pressurizing mechanism to solve the technical problem of poor forging effect after casting of products located between the rear mold and the front mold.

[0037] Please refer to the attached document. Figures 1-6 This application provides a molding machine for use in a locking and pressurizing mechanism, including a base 10, a front mold plate 20, a guide column 30, a rear mold plate 40, and a locking and pressurizing assembly 50.

[0038] The base 10 serves as a support component for the molding machine of the locking and pressurizing mechanism, supporting the front mold plate 20, guide pillars 30, rear mold plate 40, and locking and pressurizing assembly 50. The base 10 can be a flat plate, and the locking and pressurizing mechanism is arranged laterally.

[0039] The front mold plate 20 is fixed to the base 10 and is located at the front end of the base 10. The front mold plate 20 is equipped with and supports the front mold, and at this time, the front mold is fixed to the front mold plate 20.

[0040] The guide pillars 30 are connected to the front mold plate 20 and are located on the outside of the front mold. The guide pillars 30 extend in the front-back direction. There are four guide pillars 30, which are distributed around the front mold plate 20.

[0041] Optionally, the guide post 30 is provided with a limiting groove 31, in which case the limiting groove 31 is a hemispherical groove.

[0042] The rear mold plate 40 is movably sleeved on the guide post 30 and moves along the axial direction of the guide post 30. At this time, the guide post 30 guides the back-and-forth movement of the rear mold plate 40, ensuring the movement stability of the rear mold plate 40.

[0043] The rear mold plate 40 is equipped with a rear mold and supports the rear mold. The rear mold is located on the front side of the rear mold plate 40 and faces the front mold so that the rear mold can fit into the front mold.

[0044] The locking and pressurizing assembly 50 includes a locking plate 51, a limiting pin 511, and a pressurizing cylinder 52. The locking plate 51 is sleeved on the guide post 30 and locked and fixed with the guide post 30. The fixed end of the pressurizing cylinder 52 is connected to the locking plate 51, and the telescopic end is connected to the rear mold plate 40, which drives the rear mold plate 40 to move toward the front mold plate 20, so that the rear mold is further fitted to the front mold.

[0045] In this process, when the rear mold and the front mold are in the initial mold-closing state, the locking plate 51 is sleeved on the guide post 30 and locked and fixed with the guide post 30. The fixed end of the booster cylinder 52 is connected to the locking plate 51, and the telescopic end is connected to the rear mold plate 40, which drives the rear mold plate 40 to move towards the front mold plate 20, so that the rear mold is further fitted to the front mold, making the fit between the rear mold and the front mold tighter, improving the mold-closing strength between the rear mold and the front mold, and preventing the rear mold and the front mold from expanding when subjected to the impact force of forging, avoiding the gap between the rear mold and the front mold when subjected to the impact force of forging, improving the forging effect of the product after casting between the rear mold and the front mold, thereby increasing the density of the product to meet the usage conditions of high-density products required in specific environments.

[0046] When the locking plate 51 is locked to the guide post 30, the initial position of the pressure cylinder 52 and the rear mold plate 40 is ensured, and the locking force between the locking plate 51 and the guide post 30 is used for positioning. The telescopic end of the pressure cylinder 52 is connected to the rear mold plate 40, and further drives the rear mold plate 40 to move towards the front mold plate 20, so that the rear mold is further pressed against the front mold under the pressure of the pressure cylinder 52, making the fit between the rear mold and the front mold tighter, improving the mold closing strength between the rear mold and the front mold, and preventing the rear mold and the front mold from expanding when subjected to the impact force of forging, avoiding the gap between the rear mold and the front mold when subjected to the impact force of forging, improving the forging effect of the product after casting between the rear mold and the front mold, thereby increasing the density of the product to meet the use conditions of high-density products required in specific environments.

[0047] The locking plate 51 is connected to a limiting pin 511, which is rotatably mounted on the locking plate 51. The locking plate 51 has a through hole, through which the guide post 30 passes and is rotatably connected, so that the guide post 30 can rotate relative to the locking plate 51.

[0048] The limiting pin 511 rotates relative to the locking plate 51 and is arranged relative to the limiting groove 31 so that the limiting pin 511 can engage or disengage from the limiting groove 31. At this time, the locking plate 51 and the guide post 30 are locked or unlocked by the limiting pin 511.

[0049] At this time, when the limiting pin 511 is engaged with the limiting groove 31, the locking plate 51 is locked to the guide post 30. When the limiting pin 511 is disengaged from the limiting groove 31, the locking plate 51 and the guide post 30 are in the unlocked state.

[0050] Specifically, the limiting pin 511 is provided with a hemispherical groove 5111, which is arranged relative to the limiting groove 31. In the first state of the limiting pin 511, the hemispherical groove 5111 is connected to the through hole and fits the outer wall of the guide post 30. In the second state of the limiting pin 511, the hemispherical groove 5111 faces away from the through hole, and the limiting pin 511 engages with the limiting groove 31. One end of the limiting pin 511 is provided with a knob 5112, which is located on the outside of the locking plate 51 and is rotated by the user to adjust the first or second state of the limiting pin 511.

[0051] In addition, a transition plate 53 is provided between the locking plate 51 and the booster cylinder 52. One side of the transition plate 53 is fixed to the locking plate 51, and the other side is fixed to the fixed end of the booster cylinder 52.

[0052] Furthermore, a forging assembly 60 is connected to the rear machine plate 61. The forging assembly 60 is fixed to the rear machine plate 61 and moves with the movement of the rear machine plate 61. At this time, the forging assembly 60 includes the rear machine plate 61, a first forging cylinder 62, and a first forging rod 63. The rear machine plate 61 is fixed to the rear die plate 40. The fixed end of the first forging cylinder 62 is connected to the rear machine plate 61. The first forging rod 63 passes through the rear machine plate 61 and the rear die plate 40, and acts on the product located between the rear die and the front die under the drive of the extension end of the first forging cylinder 62.

[0053] At this time, the fixed end of the booster cylinder 52 is connected to the locking plate 51, and the telescopic end is connected to the rear mold plate 40, which drives the rear mold plate 40 to move toward the front mold plate 20, so that the rear mold is further fitted to the front mold, so that the fit between the rear mold and the front mold is tighter, improving the mold closing strength between the rear mold and the front mold, and preventing the rear mold and the front mold from expanding when subjected to the impact force of forging, avoiding the gap between the rear mold and the front mold when subjected to the impact force of forging, improving the forging effect of the product after casting between the rear mold and the front mold, thereby increasing the density of the product to meet the usage conditions of high-density products required in specific environments.

[0054] Optionally, the rear mold plate 61 is slidably mounted on the base 10 and can move in the front-to-back direction. The rear mold plate 61 is connected to a mold closing cylinder 70, the fixed end of which is connected to the base 10 and the telescopic end is connected to the rear mold plate 61, and drives the rear mold plate 61 to move in the front-to-back direction so that the rear moves toward the front mold, realizing the initial mold closing of the rear mold and the front and rear.

[0055] Optionally, the front mold plate 20 is connected to a second forging cylinder 80. The second forging cylinder 80 is installed on the front mold plate 20 and connected to a corresponding second forging rod. The second forging rod acts on the product located between the rear mold and the front mold under the drive of the extension end of the second forging cylinder 80.

[0056] A feeding hole is provided between the rear mold and the front mold. The feeding hole can be located on the lower side of the molding space of the molding machine, or it can be adjusted according to the actual situation.
