Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an open forging mold. Background Technology

[0002] Plastic forming technology is an important component of advanced manufacturing, and die forging is the preferred method for producing important load-bearing structural components. Die forging is divided into open die forging and closed die forging. Among many processes, open die forging, through its core feature "flash groove," creates enormous resistance at the end of forging, forcing the metal to fill the most complex and delicate parts of the die cavity. This allows for the production of forgings with extremely complex shapes, thus requiring the design of an open die forging mold.

[0003] To this end, patent CN208495687U discloses an open forging die, including an upper die and a lower die, with upper and lower parts corresponding to a pre-forging cavity on the upper and lower dies respectively. The pre-forging cavity is characterized by: a frustum forming part, with a high frustum forming part located at one end of the pre-forging cavity; the lower die has closed sealing blocks formed on both sides of the frustum forming part along the width of the die, with rounded corners at the edges near the inner side of the lower die; the two closed sealing blocks are recessed inward at the middle of the side near the frustum forming part, forming a material-blocking wall; the upper die has a closed recess for the closed sealing block to be inserted; a material-blocking protrusion is formed on the side of the closed recess near the frustum forming part, the surface of the material-blocking protrusion fitting against the material-blocking wall, and the entire closed sealing block and the entire closed recess fitting together. The open forging die of this utility model, by adopting a partially closed structure, achieves the forming of a high-pressure nozzle.

[0004] Although the open forging die mentioned above makes it easy to close the upper and lower molds during use, it is inconvenient to demold when manufacturing complex products. Therefore, it is necessary to design an open forging die. Utility Model Content

[0005] The purpose of this invention is to provide an open forging die to solve the problem of inconvenient demolding when manufacturing complex products using existing open forging dies.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an open forging die, including a base;

[0007] A centering structure is fixed at the middle position of the top of the base, and lower mold bases are provided on both sides of the centering structure;

[0008] Each of the lower mold bases has a mold-separating structure fixed on the outer wall away from the centering structure. The mold-separating structure includes mounting plates fixed to both sides of the top of the base. An electric push rod is fixed to one side of the mounting plate. The mold-separating structure also includes guide blocks fixed to the outer walls of both sides of the lower mold base. Each guide block has a guide rod penetrating through it. Both ends of the guide rod are fixed with support plates.

[0009] A bracket is fixed above the base, a lifting assembly is fixed at the bottom of the bracket, and a demolding structure is fixed at the bottom of the lifting assembly.

[0010] Preferably, one end of the electric push rod is fixedly connected to the outer wall of the lower mold base, the bottom end of the support plate is fixedly connected to the top end of the base, and both ends of the guide rod are fixedly connected to one side of the support plate.

[0011] Preferably, the centering structure includes a mandrel, a positioning shaft, a positioning groove, and a positioning seat. The mandrel is fixed at the middle position of the top of the base, the top of the mandrel is fixed with the positioning shaft, the positioning seat is fixed at the middle position of the bottom of the lifting assembly, and the bottom of the positioning seat is provided with a positioning groove.

[0012] Preferably, the central axis of the positioning groove and the central axis of the positioning shaft are collinear.

[0013] Preferably, the demolding structure includes an electric telescopic rod, a mounting frame, a mold opening base, and a semi-mold cavity. The mounting frame is uniformly fixed at the edge of the bottom end of the lifting assembly. An electric telescopic rod is fixed to one side of the mounting frame. A mold opening base is fixed to one end of each electric telescopic rod. A semi-mold cavity is uniformly opened on the side of the mold opening base near the positioning seat.

[0014] Preferably, the mounting brackets are evenly distributed at the bottom of the lifting assembly.

[0015] Preferably, the semi-mold cavities are symmetrically distributed on both sides of the mold opening base.

[0016] Preferably, the lifting assembly includes a guide shaft, a hydraulic rod, and a top plate. The hydraulic rod is fixed at the middle position of the bottom end of the support, the bottom end of the hydraulic rod is fixed with the top plate, and the top ends of the top plate are both fixed with guide shafts.

[0017] Preferably, the top end of the guide shaft extends to the outside of the bracket and is slidably connected to the bracket.

[0018] The open-type forging die provided by this utility model has the following advantages:

[0019] By setting a mold splitting structure, the lower mold bases on both sides of the centering structure can be moved away from the centering structure by driving the electric push rod, which facilitates the demolding of the molded product between the lower mold base and the centering structure. This avoids the protrusion at the top edge of the product, which makes demolding inconvenient. This device has the function of easy demolding and improves the convenience of using the open die forging mold.

[0020] By setting up a centering structure and ensuring that the central axes of the positioning shaft and the positioning groove are collinear, the upper and lower molds can be aligned when the molds are closed, avoiding deviations when the upper and lower molds are closed. This device has the function of facilitating the centering and positioning of the molds, and improves the convenience of using the open forging mold.

[0021] By incorporating a demolding structure, the upper mold can be divided into three parts via an electric telescopic rod, facilitating demolding of the top of irregularly shaped products and preventing the top of the product from being unable to be demolded due to inversion. This device enables convenient demolding of the top of the product, improving the convenience and efficiency of the open forging die during use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 The present invention provides an open forging die, including a base 1.

[0030] Reference Figures 2-5 A centering structure 4 is fixed at the middle position of the top of the base 1. The centering structure 4 includes a spindle 41, a positioning shaft 42, a positioning groove 43, and a positioning seat 44. The spindle 41 is fixed at the middle position of the top of the base 1. The top of the spindle 41 is fixed with the positioning shaft 42. The positioning seat 44 is fixed at the middle position of the bottom of the lifting assembly 6. The bottom of the positioning seat 44 is provided with a positioning groove 43. The central axis of the positioning groove 43 and the central axis of the positioning shaft 42 are collinear. Lower mold seats 3 are provided on both sides of the centering structure 4.

[0031] During the mold closing process, the positioning seat 44 and positioning groove 43 fixed at the bottom of the top plate 63 contact the positioning shaft 42 fixed at the top of the mandrel 41. When the positioning shaft 42 enters the positioning groove 43, it can ensure that the upper mold and the lower mold are in a centered state, thus ensuring the quality of product molding.

[0032] Reference Figures 1-3 and Figure 5 As shown, a mold-separating structure 2 is fixed on the outer wall of the lower mold base 3 on the side away from the centering structure 4. The mold-separating structure 2 includes mounting plates 21 fixed on both sides of the top of the base 1. An electric push rod 22 is fixed on one side of the mounting plate 21. The mold-separating structure 2 also includes guide blocks 25 fixed on both sides of the outer wall of the lower mold base 3. A guide rod 24 passes through the interior of each guide block 25. A support plate 23 is fixed at both ends of each guide rod 24. One end of the electric push rod 22 is fixedly connected to the outer wall of the lower mold base 3. The bottom end of each support plate 23 is fixedly connected to the top of the base 1. Both ends of each guide rod 24 are fixedly connected to one side of the support plate 23.

[0033] When the mold is closed, the electric push rod 22 extends, and the two sets of lower mold bases 3 move along the guide rod 24 toward the centering structure 4 until the lower mold bases 3 abut against each other to complete the mold closing. The inner side of the lower mold base 3 and the outer side of the centering structure 4 together form the bottom mold cavity. When the mold is separated, after the upper mold is lifted, the electric push rod 22 retracts, driving the lower mold bases 3 on both sides to move outward horizontally along the guide rod 24 in sync, making room and creating conditions for the forging to be removed and demolded.

[0034] Reference Figures 1-4As shown, a bracket 7 is fixed above the base 1, and a lifting assembly 6 is fixed at the bottom of the bracket 7. The lifting assembly 6 includes a guide shaft 61, a hydraulic rod 62, and a top plate 63. The hydraulic rod 62 is fixed at the middle position of the bottom of the bracket 7, and the bottom of the hydraulic rod 62 is fixed to the top plate 63. Guide shafts 61 are fixed on both sides of the top of the top of the top plate 63. The top of the guide shafts 61 extends to the outside of the bracket 7 and is slidably connected to the bracket 7. A demolding structure 5 is fixed at the bottom of the lifting assembly 6. The demolding structure 5 includes an electric telescopic rod 51, a mounting frame 52, a mold opening seat 53, and a semi-mold cavity 54. The mounting frame 52 is evenly fixed at the edge of the bottom of the lifting assembly 6. An electric telescopic rod 51 is fixed on one side of the mounting frame 52. A mold opening seat 53 is fixed at one end of the electric telescopic rod 51. A semi-mold cavity 54 is evenly opened on the side of the mold opening seat 53 near the positioning seat 44. The mounting frames 52 are evenly distributed at the bottom of the lifting assembly 6, and the semi-mold cavities 54 are symmetrically distributed on both sides of the mold opening seat 53.

[0035] When the mold splitting structure 2 moves the lower mold base 3 away, the forging stays at the top of the base 1. After receiving the signal, the electric telescopic rod 51 starts and moves the mold opening base 53 and the half mold cavity 54 outward to make room at the top of the product. Then, the hydraulic rod 62 is activated, which drives the demolding structure 5 to move upward as a whole, exposing the product to the outside, which is convenient for subsequent cooling and removal of the product.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
