Description

Technical Field

[0001] The utility model relates to the technical field of zinc alloy inclined ejector die, in particular to a zinc alloy inclined ejector die. Background Technique

[0002] The die inclined ejector, also known as inclined pin or inclined ejector, is a common term in the die industry in the Pearl River Delta region mainly composed of Hong Kong-funded die factories. It is a mechanism used in die design to form internal undercuts of products and is suitable for relatively simple undercut situations.

[0003] When the parts in the die are demolded during the current zinc alloy die-casting forming, the parts are usually taken out manually. In many cases, there are undercuts in the fixed die direction of the product, making demolding difficult and the work efficiency low. The zinc alloy can be ejected obliquely from the die through the inclined ejector block. As the number of ejection times increases, the inclined ejector block may get stuck, which may affect the demolding effect of the die. This is mainly because the sliding device wears and rusts after long-term use. Therefore, a zinc alloy inclined ejector die is proposed, which can easily disassemble the slider from the inside of the trapezoidal push block for maintenance and grinding, and avoid the slider rusting and affecting the sliding effect after long-term use. Content of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides a zinc alloy inclined ejector die, which can easily disassemble the slider from the inside of the trapezoidal push block for maintenance and grinding, and avoid the slider rusting and affecting the sliding effect after long-term use.

[0005] The technical solution adopted by the utility model to solve its technical problems is a zinc alloy inclined ejector die, including a trapezoidal push block. The inclined top surface of the trapezoidal push block is provided with a main chute for the main slider to slide and install. A limit block is fixedly installed at the top of the main chute through bolts. An oil passage groove is opened inside the limit block. Two pulley grooves are also opened inside the main chute. The two pulley grooves are used for the pulleys to slide and place. The pulleys are movably installed at one end of the main slider, and there are multiple pulleys.

[0006] By adopting the above technical solution, the oil passage groove opened inside the limit block can inject lubricating oil to lubricate between the main slider and the main chute through the oil passage groove, and cooperate with the sliding of the pulley in the pulley groove to improve the sliding efficiency of the main slider and avoid situations such as sliding jams.

[0007] By disassembling the limit block, the main slider can be disassembled from the main chute, which is convenient for maintaining and grinding the main slider and improving the service life of the main slider.

[0008] Specifically, auxiliary chutes are provided on both sides of the main chute. The auxiliary chutes are used for slidably mounting auxiliary sliders, and auxiliary sliders are fixedly connected to both sides of the main slider.

[0009] By adopting the above technical solution, the auxiliary sliders can also slide together with the main slider. The auxiliary sliders slide inside the auxiliary chutes. The main function of the auxiliary sliders is to limit the main slider.

[0010] Specifically, the center of the bottom end of the trapezoidal push block is fixedly connected to the top end of the piston push rod, and the bottom end of the piston push rod is fixedly connected to the output end of the electric cylinder.

[0011] By adopting the above technical solution, the trapezoidal push block will be pushed upward or downward by the piston push rod when the electric cylinder is started.

[0012] Specifically, the electric cylinder is fixedly installed inside the electric box. The top end of the electric box is movably inserted with a plurality of telescopic rods. The top ends of the plurality of telescopic rods are fixedly connected to the bottom end of the trapezoidal push block.

[0013] By adopting the above technical solution, the plurality of telescopic rods can reinforce and stabilize the bottom of the trapezoidal push block.

[0014] Specifically, one end of the main slider away from the pulley is fixedly connected to one end of the inclined ejector rod, and the other end of the inclined ejector rod is fixedly connected to the bottom end of the inclined ejector block.

[0015] By adopting the above technical solution, the downward sliding of the main slider can drive the inclined ejector rod to move obliquely upward, and then the inclined ejector block can eject the zinc alloy obliquely from the bottom of the mold.

[0016] Specifically, a threaded hole is provided in the upper inner part of the main chute, and the threaded hole is adapted to a bolt.

[0017] By adopting the above technical solution, the limiting block can be fixed to the inner top of the main chute by docking and installing the bolt with the threaded hole.

[0018] Advantages of the present utility model:

A limit block 13 is fixedly installed at the top of the main chute 3 through a bolt 9. An oil through groove 14 is provided inside the limit block 13. Two pulley grooves 10 are also provided inside the main chute 3. The two pulley grooves 10 are used for the pulley 11 to slide and be placed. The pulley 11 is movably installed at one end of the main slider 12, and multiple pulleys 11 are provided.

[0030] In use, in conjunction with the sliding of the pulley 11 in the pulley groove 10, the main slider 12 can move obliquely downward along the direction of the main chute 3, and appropriate lubricating oil can be injected through the oil passage 14 of the limit block 13 before the main slider 12 slides. The lubricating oil passing through the oil passage 14 will drip into the interior of the main chute 3, lubricating between the main chute 3 and the main slider 12.

[0031] Exemplarily, as Figures 1 - 5 shown, the present utility model further includes that auxiliary chutes 15 are provided on both sides of the main chute 3 for slidably mounting auxiliary sliders 17, and auxiliary sliders 17 are fixedly connected to both sides of the main slider 12.

[0032] In use, the auxiliary sliders 17 can also slide together with the main slider 12, and the auxiliary sliders 17 slide inside the auxiliary chutes 15. The main function of the auxiliary sliders 17 is to limit the main slider 12.

[0033] Exemplarily, as Figures 1 - 5 shown, the present utility model further includes that the center of the bottom end of the trapezoidal push block 6 is fixedly connected to the top end of the piston push rod 2, and the bottom end of the piston push rod 2 is fixedly connected to the output end of the electric cylinder 8.

[0034] In use, the trapezoidal push block 6 is pushed upward or downward by the piston push rod 2 when the electric cylinder 8 is activated.

[0035] Exemplarily, as Figures 1 - 5 shown, the present utility model further includes that the electric cylinder 8 is fixedly installed inside the electric box 1, and a telescopic rod 7 is movably inserted into the top end of the electric box 1. There are multiple telescopic rods 7, and the top ends of the multiple telescopic rods 7 are fixedly connected to the bottom end of the trapezoidal push block 6.

[0036] In use, the multiple telescopic rods 7 can reinforce and stabilize the bottom of the trapezoidal push block 6.

[0037] Exemplarily, as Figures 1 - 5 shown, the present utility model further includes that one end of the main slider 12 away from the pulley 11 is fixedly connected to one end of the inclined ejector rod 4, and the other end of the inclined ejector rod 4 is fixedly connected to the bottom end of the inclined ejector block 5.

[0042] When the main slider 12 needs to be maintained, the main slider 12 can be disassembled from the main chute 3. First, unscrew the bolt 9 of the limit block 13, and slide the limit block 13 obliquely upward along the direction of the main chute 3. Then start the electric cylinder 8 through an external power supply. The electric cylinder 8 drives the piston push rod 2 and the trapezoidal push block 6 to move downward. At the same time, the main slider 12 and the auxiliary slider 17 will also slide out along the direction of the main chute 3, so that the main slider 12 and the auxiliary slider 17 can be maintained and polished.
