Description

Technical Field

[0001] The utility model relates to the field of mold equipment, in particular to a special-shaped hard alloy extrusion mold. Background Art

[0002] Extrusion dies are an important industrial tool, widely used in many industries such as aluminum profile processing, plastic processing, and electronic chip fields; its main function is to process materials such as metals or plastics into the desired shape and size through extrusion molding.

[0003] The extrusion die is generally made of cemented carbide. When in use, the raw material passes through the inside of the die body, so that the material is extruded and formed. However, the initially formed material will generate a lot of heat due to its deformation after extrusion. When the formed raw material is discharged, the raw material suddenly cools down, causing the formed raw material to deform, resulting in a section of severely deformed waste, resulting in a waste of raw materials. Therefore, a device is urgently needed to solve the above problem. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a special-shaped cemented carbide extrusion die, including a die sleeve 1 and a die main body 4. The die main body 4 slides inside the die sleeve 1. The cross-section of the die main body 4 is rectangular, which prevents the die main body 4 from rotating around the axis inside the die sleeve 1. There are limiting mechanisms on both sides of the die main body 4 for conveniently limiting the position of the die main body 4. A serpentine tube 3 is inlaid and fixed inside the die sleeve 1. Both sides of the serpentine tube 3 are fixedly extended to the outside of the die sleeve 1, and the serpentine tube 3 is spirally wrapped around the outside of the die main body 4. A water injection pipe 5 is fixed on one side of the serpentine tube 3 through a connecting valve. When in use, cooling water is injected into the serpentine tube 3 through the water injection pipe 5, so that the cooling water surrounds the outside of the die main body 4, so that the outside of the die main body 4 is cooled. When the extrusion molding work is performed, the raw material is deformed to generate heat, and the cooling water is used to cool the raw material, so that the raw material is cooled inside the die main body 4. The forming hole of the die main body 4 is limited to ensure that the temperature difference between the inside and the outside is small when the raw material is discharged, thereby preventing the raw material from being deformed when being discharged, ensuring the extrusion quality, and preventing the waste of raw materials.

[0021] The limiting mechanism includes a limiting component, a screw hole 9, a screw rod 11, a groove body 10, a hole groove 12 and a baffle 2. The limiting component is on the outside of the mold sleeve 1. The screw holes 9 are symmetrically arranged at the upper and lower sides of the mold sleeve 1. The baffle 2 covers the outside of the mold sleeve 1. There are two baffles 2, which symmetrically cover the upper and lower sides of the mold sleeve 1. The groove body 10 is arranged on the outside of the baffle 2. The screw rod 11 moves through the center position of the groove body 10. One side of the screw rod 11 is threaded into the screw hole 9, so that the baffle 2 is fixed on the outside of the mold sleeve 1. The hole groove 12 is arranged at the center position of the baffle 2. The hole groove 12 has the same shape as the forming hole in the center of the mold body 4.

[0022] The limiting assembly includes a fixing ring 6, a fixing rod 7 and a limiting block 8. The fixing ring 6 is welded and fixed on the outside of the mold sleeve 1, and the fixing rod 7 is welded and fixed on the fixing ring 6. There are two fixing rods 7, which are symmetrically fixed on both sides of the fixing ring 6. The limiting block 8 is movably sleeved on the outside of the fixing rod 7. When in use, after the baffle 2 is fixed, the limiting block 8 is rotated so that the limiting block 8 overlaps the outside of the baffle 2. In this way, when the mold body 4 is in use, the limiting block 8 is used to assist in the force, so as to prevent the mold body 4 from squeezing the baffle 2 when the force is applied, and the baffle 2 is subjected to excessive force, causing the position of the screw 11 to deform.

[0023] Working principle: when in use, cooling water is injected into the serpentine tube 3 through the water injection pipe 5, so that the cooling water surrounds and passes through the outside of the mold body 4, so that the outside of the mold body 4 is cooled down. When extrusion molding is performed, the raw material deforms and generates heat, and the cooling water is used to cool the raw material, so that the raw material is cooled down inside the mold body 4. The forming hole of the mold body 4 is limited to ensure that the temperature difference between the inside and outside of the raw material is small when the raw material is discharged, thereby preventing the raw material from deforming when it is discharged, ensuring the extrusion quality, and preventing the waste of raw materials; when in use, after the baffle 2 is fixed, the limit block 8 is rotated so that the limit block 8 overlaps the outside of the baffle 2, so that when the mold body 4 is in use, the limit block 8 is used to assist the force, to prevent the baffle 2 from being squeezed when the mold body 4 is subjected to force, and the baffle 2 is subjected to excessive force, causing the position of the screw 11 to deform.
