Description

Technical Field

[0001] The utility model relates to the technical field of magnesium alloy extrusion dies, in particular to an anti-dislocation magnesium alloy extrusion die. Background Art

[0002] Magnesium alloy extrusion dies are tools specially used for extrusion molding of magnesium alloy materials. During the extrusion process of magnesium alloys, the design and manufacturing quality of the die have an important influence on the shape, size and performance of the final product.

[0003] Chinese patent authorization announcement number CN 218873299 U discloses an anti-dislocation extrusion die, including a bottom plate, the upper surface of the bottom plate is fixedly connected to two vertical plates, the upper surface of the bottom plate is fixedly connected to a lower die, the left and right sides of the lower die are fixedly connected to a stabilizing plate, the upper surface of each stabilizing plate is provided with two sliding holes, the side of the two stabilizing plates away from each other is respectively fixedly connected to the side of the two vertical plates close to each other, and an upper die is arranged above the lower die. The anti-dislocation extrusion die, through the cooperation of the connecting plate, stabilizing rod, stabilizing plate, sliding hole and through hole, can use the stabilizing rod to connect the connecting plate and the stabilizing plate, forming the positioning between the upper die and the lower die. When the extrusion work is performed, the upper die can drive the stabilizing rod to move downward, which can ensure the predetermined position between the upper die and the lower die, so that the extruded workpiece meets the predetermined standard to avoid the waste of raw materials.

[0004] However, after a long period of extrusion in the above-mentioned prior art, since the upper mold is fixed on the electric push rod, and the connecting plates at both ends and the stabilizing rod at the bottom of the connecting plates are fixed to the upper mold, when the upper mold is offset and misaligned, it is not convenient to replace the upper mold alone, and when replacing, the connecting plates and the stabilizing rods need to be replaced together, which increases its production cost. Therefore, there is an urgent need for an anti-misalignment magnesium alloy extrusion mold. Utility Model Content

[0005] The utility model aims to provide a magnesium alloy extrusion die with an anti-dislocation function, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a dislocation-proof magnesium alloy extrusion die, comprising a bottom plate, characterized in that: four limiting holes are opened on the top of the bottom plate, a lower die is arranged on the top of the bottom plate, an upper die is arranged just above the lower die, and both ends of the upper die are respectively fixedly connected with fixed plates, and the fixed plates are respectively opened with perforations corresponding to the limiting holes;

[0009] When processing magnesium alloy, the upper mold is pushed by a hydraulic rod for extrusion. Fixed plates are respectively provided at both ends of the upper mold. The fixed plates are provided with through holes. The four limit rods at the bottom of the mounting plate are respectively inserted into the through holes. When extrusion is performed, the four limit rods will extend downward into the limit holes respectively, and then the limit rods will extend into the limit holes normally to ensure that the upper mold will not be misaligned.

[0010] Preferably, the left side of the bidirectional screw movably passes through the transverse plate and is fixedly connected to the motor, and the right side of the bidirectional screw is movably connected to the clamping groove.

[0011] Preferably, the front and rear ends of the lower mold are respectively fixedly connected with ear plates, and the ear plates are respectively connected to the bottom plate by bolts.

[0012] When misalignment occurs during long-term extrusion work, the motor drives the bidirectional screw to move the clamping blocks outward at the same time, so that the clamping blocks are pulled out of the fixed grooves respectively, and the mounting plate and the upper mold can be removed, which is convenient for their separate replacement, reducing their production costs. Ear plates are respectively provided on the front and rear sides of the lower mold, and the ear plates are connected to the bottom plate with bolts, which also facilitates the replacement and disassembly of the lower mold.

[0013] Preferably, two groups of rod sleeves are fixedly connected to the top of the base plate, each two of the rod sleeves form a group, and sliding rods are respectively inserted into the ends of the two groups of rod sleeves close to each other, springs are respectively arranged inside the two groups of rod sleeves, and baffles are respectively fixedly connected to the ends of the sliding rods close to each other, and through holes matching the base plate are respectively opened on the tops of the baffles.

[0014] Preferably, one end of the spring is fixedly connected to the sliding rod, and the other end of the spring is connected to the rod sleeve.

[0015] When the lower mold is misaligned, the two ends of the lower mold will contact the baffle, and the baffle will contact the sliding rod to shrink the spring, thereby causing the through hole on the baffle to be misaligned with the limit hole, so that the limit column cannot pass through the through hole into the limit hole normally, thereby alerting the operator that the lower mold is misaligned, reducing defects in the product caused by misalignment during extrusion.

[0016] Preferably, a supporting leg is fixedly connected to the bottom of the base plate, and four supporting legs are provided.

[0019] Second, according to the utility model, when the lower mold is misaligned, the two ends of the lower mold will contact the baffle, and the baffle will contact the slide bar to shrink the spring, thereby causing the through hole on the baffle to be misaligned with the limit hole, so that the limit column cannot normally pass through the through hole into the limit hole, thereby alerting the operator that the lower mold is misaligned, reducing the possibility of defects in the product when it is extruded due to the misalignment.

[0033] Through the above technical scheme, when processing magnesium alloy, the upper mold 3 is pushed by the hydraulic rod 12 to perform extrusion work, and fixed plates 4 are respectively provided at both ends of the upper mold 3. The fixed plates 4 are provided with through holes, and the four limit rods 19 at the bottom of the mounting plate 18 are respectively inserted into the through holes. When extrusion is performed, the four limit rods 19 will extend downward into the limit holes respectively, and then the limit rods 19 will normally extend into the limit holes to ensure that the upper mold 3 will not be misaligned.

[0037] The bottom of the base plate 1 is fixedly connected with a supporting leg 26 , and four supporting legs 26 are provided.

[0038] Through the above technical solution, when the lower mold 2 is misaligned, the two ends of the lower mold 2 will contact the baffle 25, and the baffle 25 will contact the slide bar 23 to shrink the spring 24, thereby causing the through hole on the baffle 25 to be misaligned with the limiting hole, so that the limiting column cannot normally pass through the through hole into the limiting hole, thereby alerting the operator that the lower mold 2 is misaligned, reducing the possibility of defects in the product caused by the misalignment during extrusion.

When misalignment occurs during long-term extrusion work, the motor 14 drives the bidirectional screw 15 to move the clamping blocks 16 outward at the same time, so that the clamping blocks 16 are respectively drawn out of the fixed grooves.
