Description
Technical Field
[0001] The utility model relates to the technical field of moulds, in particular to a forging double-cavity mould. Background Art
[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes, and is one of the two major components of forging (forging and stamping). Through forging, defects such as as-cast porosity generated during the smelting process of metals can be eliminated, the microstructure can be optimized. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally superior to those of castings made of the same material. For important parts with high loads and severe working conditions in related machinery, except for those with relatively simple shapes that can use rolled plates, profiles or welded parts, forgings are mostly used.
[0003] Existing forging moulds use single-cavity forging, and only one forging can be produced at a time, which greatly affects the production efficiency of forgings; especially in the case of mass production of forgings, single-cavity forging moulds are difficult to meet the production demand. Content of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the utility model provides a forging double-cavity mould that can simultaneously forge two forgings through a bottom mould, an intermediate mould and a top mould arranged in sequence, increasing the production efficiency of forgings, being simple, efficient, safe, reliable and convenient to operate.
[0005] The utility model is realized through the following technical solutions. A forging double-cavity mould is provided, including a bottom mould with a cavity A opened at the top. Guide posts extending in the vertical direction are fixed on the bottom mould. A top mould that slides in the vertical direction is arranged on the guide posts. A cavity D is opened at the bottom of the top mould. An intermediate mould is arranged between the bottom mould and the top mould, and the intermediate mould slides in the vertical direction on the guide posts. A cavity B adapted to the cavity A is arranged at the bottom of the intermediate mould, and a cavity C adapted to the cavity D is arranged at the top of the intermediate mould. Two forgings are simultaneously forged through the bottom mould, the intermediate mould and the top mould arranged in sequence, increasing the production efficiency of forgings.
[0006] As an optimization, reset springs extending in the vertical direction are respectively arranged between the bottom mould and the intermediate mould and between the top mould and the intermediate mould. The reset springs are sleeved on the guide posts. The bottom mould, the intermediate mould and the top mould are separated by the reset springs, facilitating the addition of materials and the removal of forgings.
[0007] As an optimization, reset grooves extending in the vertical direction are opened at the top of the bottom mould, the bottom of the top mould, and the top and bottom of the intermediate mould. The reset springs are located in the reset grooves. The reset springs are received through the reset grooves, and when forging, the gaps between the bottom mould, the intermediate mould and the top mould are reduced.
[0008] As an optimization, grooves extending in the vertical direction are respectively provided at the bottoms of the mold cavities A, B, C, and D. Sliders that slide in the vertical direction are provided in the grooves, and the sliders are connected to the bottoms of the grooves by unloading springs extending in the vertical direction; demolding is automatically performed through the sliders and the unloading springs, increasing the production efficiency of forgings.
[0009] As an optimization, guide rods extending in the vertical direction are fixedly provided in the grooves. The sliders are slidably arranged on the guide rods, and the unloading springs are sleeved on the guide rods; the guide rods support the unloading springs and guide the movement direction of the unloading springs to prevent the unloading springs from deflecting.
[0010] As an optimization, limiting grooves are provided in the grooves. The sliders are slidably arranged in the limiting grooves, and the sizes of the sliders and the bottom surfaces of the limiting grooves are both larger than the size of the bottom surface of the groove; the sliders are supported by the limiting grooves to prevent the unloading springs from being damaged during forging, thereby causing the mold cavities to change.

The top die 3 forges the materials on the intermediate die 2 and drives the intermediate die 2 to move downward. The intermediate die 2 forges the materials on the bottom die 1 until the forging of the forgings is respectively completed between the cavity A 101 and the cavity B 201 and between the cavity C 202 and the cavity D 301. Then, the top die 3 and the intermediate die 2 are respectively slid upward along the guide pillar 4. The staff takes out the completed forgings and puts new materials on the cavity A 101 and the cavity C 202 to start the next round of forging work.

The slider 8 is slidably sleeved on the guide rod 10, and the discharge spring 9 is sleeved on the guide rod 10; a counterbore adapted to the guide rod 10 is provided at one end of the slider 8 facing the guide rod 10, and the guide rod 10 slidably passes through the counterbore.
[0031] When forging, the material pushes the slider 8 to move along the guide rod 10 toward the inside of the groove 7; after the forging is completed, the discharge spring 9 pushes the slider 8 to move outward along the guide rod 10.
[0032] As Figure 1 、 Figure 2 andFigure 3 A limiting groove 11 is provided in the groove 7 shown, and the slider 8 is slidably arranged in the limiting groove 11, and the dimensions of the slider 8 and the bottom surface of the limiting groove 11 are both larger than the dimensions of the bottom surface of the groove 7; the slider 8 and the bottom surface of the limiting groove 11 extend in the horizontal direction, the slider 8 is adapted to the limiting groove 11, and the height of the slider 8 is equal to the depth of the limiting groove 11.
[0033] During forging, the material pushes the slider 8 to move along the guide rod 10 toward the groove 7 until the bottom surface of the slider 8 contacts the bottom surface of the limiting groove 11, and the slider 8 stops moving.
[0034] In the actual production process, the staff places the materials on the die cavity A101 and the die cavity C202 respectively, and starts the hydraulic device. The telescopic rod of the hydraulic device drives the top die 3 to move downward along the guide column 4. The top die 3 forges the material on the intermediate die 2 and drives the intermediate die 2 to move downward. The intermediate die 2 forges the material on the bottom die 1; the material pushes the slider 8 to move along the guide rod 10 toward the groove 7, and the unloading spring 9 contracts until the bottom surface of the slider 8 contacts the bottom surface of the limit groove 11, and the slider 8 stops moving; at the same time, the reset spring 5 gradually contracts and enters the reset groove 6 until the forging is completed between the die cavity A101 and the die cavity B201 and between the die cavity C202 and the die cavity D301.
