Technical Field

[0001] The utility model relates to the technical field of casting machines, in particular to a vertical squeeze casting machine for aluminum alloy casting that prevents pouring splashing. Background Technique

[0002] With the development and progress of technology, more and more parts require special processing requirements. Aluminum is a silver-white light metal with good ductility. Aluminum can be doped with various different metals to be made into alloys to achieve the characteristics and requirements of being strong and light. Casting is one of the common ways for aluminum alloy forming. After heating to melt and mix aluminum with other metals, it is poured into a mold and cooled to form. Due to the poor protection of the aluminum alloy metal solution during casting, the situation of molten aluminum splashing everywhere often occurs, which is very likely to cause injuries to workers and trigger fires. Content of the Utility Model

[0003] The purpose of the utility model is to provide a vertical squeeze casting machine for aluminum alloy casting that prevents pouring splashing, so as to solve the problem that the molten aluminum splashes everywhere easily during casting mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A vertical squeeze casting machine for aluminum alloy casting that prevents pouring splashing, including a base. The base is designed in a square shape, and a middle support seat is arranged on one side of the base away from the ground, and the area of the middle support seat is smaller than that of the base. A first hydraulic cylinder is fixedly installed at one end of the base close to the middle support seat, and an upper mold is fixedly installed on one side of the middle support seat close to the first hydraulic cylinder, and a second hydraulic cylinder is fixedly installed at one end of the middle support seat away from the upper mold. A clamping mechanism is arranged on one side of the middle support seat away from the base, and the splashing aluminum water is blocked by the clamping mechanism.

[0005] Preferably, the clamping mechanism includes: a chassis. The chassis is slidably installed on one side of the middle support seat away from the first hydraulic cylinder, and a support frame is fixedly installed on the inner surface of the chassis, and the support frame and the chassis are concentrically designed. An annular groove is arranged on the inner surface of one end of the support frame away from the chassis, and a snap ring is clamped in the annular groove of the support frame, and a water-absorbing and fire-proof cloth is arranged between the snap ring and the support frame. One outer surface of one end of the water-absorbing and fire-proof cloth is attached to the side surface of the annular groove of the support frame, and one end of the water-absorbing and fire-proof cloth away from the second hydraulic cylinder is connected to the chassis, and a large amount of coolant is contained in the interior of the chassis.

[0006] By adopting the above technical solution, the coolant in the chassis can be sucked up by the water-absorbing and fire-proof cloth, so that the water-absorbing and fire-proof cloth is filled with coolant. When the splashing aluminum alloy metal liquid during casting splashes onto the water-absorbing and fire-proof cloth and cools, it then falls into the interior of the chassis, preventing the metal liquid from splashing everywhere and causing injuries to workers.

[0007] Preferably, a ball is provided inside one end of the chassis away from the second hydraulic cylinder, and the ball is slidably connected to the chassis. A thrust spring is provided between the chassis and the ball. A block-shaped protrusion is provided at one end of the chassis away from the support frame. A groove is provided on the outer surface of the middle support seat, and the groove of the middle support seat is engaged with the block-shaped protrusion of the chassis. A pit is provided in the groove of the middle support seat.

[0008] With the above technical solution, when the chassis is inserted into the groove of the middle support seat, the ball will retract into the chassis. When in place, the thrust spring will push the ball out so that the ball is engaged with the pit of the middle support seat to fix the chassis, facilitating the removal of the chassis for cleaning.

[0009] Preferably, a sliding mechanism is provided between the base and the middle support seat to automatically demold the mold after it is opened.

[0010] With the above technical solution, after the mold is opened, the cooled part can be separated from the lower mold automatically.

[0011] Preferably, the sliding mechanism includes: a guide rod. The guide rod is fixedly installed between the base and the middle support seat. A sliding seat is installed through the outer surface of the guide rod. One end of the sliding seat away from the upper mold is connected to the output end of the first hydraulic cylinder. A lower mold is fixedly installed on the outer surface of the sliding seat close to the middle support seat, and the lower mold and the sliding seat are concentrically designed. A stop block is fixedly installed on the outer surface of the base, and the outer surface of the stop block is attached to the outer surface of the sliding seat. A thimble is slidably installed inside the sliding seat, and a spring is provided between the thimble and the sliding seat. One end of the thimble penetrates the outer surface of the sliding seat, and one end of the thimble away from the first hydraulic cylinder penetrates the outer surface of the lower mold, and one end of the thimble is attached to the stop block.

[0012] With the above technical solution, by contracting the first hydraulic cylinder, the sliding seat can move along the guide rod. As the sliding seat descends, one end of the thimble will contact the stop block, causing the thimble to move and eject the part in the lower mold. At the same time, with the support of the stop block, the sliding seat is more stable.

[0013] Preferably, a pushing mechanism is provided inside the middle support seat to push the material between the molds.

One end of the material injection barrel is connected to the output end of the second hydraulic cylinder. A material injection port is penetrated and installed on the side surface of the material injection barrel, and the material injection port is designed in a funnel shape and is located inside the water-absorbing fireproof cloth.

[0016] By adopting the above technical solution, when casting, the molten aluminum alloy liquid can smoothly enter the material injection barrel along the inclined surface of the funnel-shaped material injection port, reducing the probability of the metal solution splashing out. At the same time, the inside of the material injection barrel can be made free of residual metal liquid through the push rod.

[0017] Compared with the prior art, the beneficial effects of the present utility model are: the vertical squeeze casting machine for aluminum alloy casting to prevent pouring splash:

[0018] 1. Pour the melted aluminum alloy liquid into the material injection port. When the metal liquid splashes, the metal liquid will come into contact with the inside of the water-absorbing fireproof cloth, and the water-absorbing fireproof cloth will absorb the coolant contained in the chassis, making the water-absorbing fireproof cloth wet. After being blocked by the water-absorbing fireproof cloth, the metal liquid falls into the chassis, preventing the metal liquid from splashing everywhere and collecting the splashed metal liquid at the same time;

[0019] 2. The chassis can be fixed on the middle support seat through the ball. When it is necessary to clean the chassis, just pull the chassis and remove it from the middle support seat, then the cooled metal in the chassis can be conveniently taken out. At the same time, take out the snap ring to facilitate the replacement and maintenance of the damaged water-absorbing fireproof cloth;

[0020] 3. After the metal liquid is injected into the mold and cooled and formed, the first hydraulic cylinder can be contracted to drive the sliding seat to open along the direction of the guide rod. As the sliding seat descends, the ejector pin will contact the block, causing the ejector pin to be pushed out to eject the cooled part in the lower mold. At the same time, the block can support the sliding seat to enable automatic demolding when the lower mold and the upper mold are separated. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-6 , the present utility model provides a technical solution: a vertical squeeze casting machine for aluminum alloy casting to prevent pouring splash, including a base 1. The base 1 is designed in a square shape, and a middle support seat 2 is provided on the side of the base 1 away from the ground.

And a support frame 14 is fixedly installed on the inner surface of the chassis 11. And the support frame 14 and the chassis 11 are concentrically designed. An annular groove is provided on the inner surface of the end of the support frame 14 away from the chassis 11. And a snap ring 13 is clamped and installed in the annular groove of the support frame 14. And a water-absorbing and fire-proof cloth 15 is provided between the snap ring 13 and the support frame 14. One end outer surface of the water-absorbing and fire-proof cloth 15 is attached to the side surface of the annular groove of the support frame 14. And one end of the water-absorbing and fire-proof cloth 15 away from the second hydraulic cylinder 19 is connected to the chassis 11. And a large amount of coolant is contained in the interior of the chassis 11.

[0030] A large amount of coolant is injected into the chassis 11, so that the absorbent fireproof cloth 15 clamped on the support frame 14 absorbs the coolant. The molten metal splashed during casting is blocked by the wet absorbent fireproof cloth 15, and the molten metal falls into the chassis 11 and is cooled by the coolant in the chassis 11. This prevents the molten metal from splashing and at the same time collects the cooled metal into the chassis 11.

[0031] A ball 12 is arranged inside the end of the chassis 11 away from the second hydraulic cylinder 19, and the ball 12 is slidably connected to the chassis 11, and a thrust spring is arranged between the chassis 11 and the ball 12, and a block-shaped protrusion is arranged at the end of the chassis 11 away from the support frame 14, and a groove is arranged on the outer surface of the middle support seat 2, and the groove of the middle support seat 2 is engaged with the block-shaped protrusion of the chassis 11, and a pit is arranged in the groove of the middle support seat 2.

[0032] When maintenance is required, the chassis 11 only needs to be pulled out from the groove of the support seat 2 to disengage the ball 12 from the groove, and then the chassis 11 can be cleaned, and the cooled metal in the chassis 11 can be taken out for recycling. After that, the snap ring 13 can be removed, and the water-absorbing fireproof cloth 15 can be cleaned or replaced.

[0033] A sliding mechanism is provided between the base 1 and the middle support seat 2, through which the mold is automatically demoulded after being opened, and the sliding mechanism comprises: a guide rod 5, which is fixedly installed between the base 1 and the middle support seat 2, and a sliding seat 4 is installed through the outer surface of the guide rod 5, and the end of the sliding seat 4 away from the upper mold 10 is connected to the output end of the first hydraulic cylinder 3, a lower mold 6 is fixedly installed on the outer surface of the sliding seat 4 close to the middle support seat 2, and the lower mold 6 and the sliding seat 4 are concentrically designed, a stopper 9 is fixedly installed on the outer surface of the base 1, and the outer surface of the stopper 9 is in contact with the outer surface of the sliding seat 4, an ejector pin 7 is slidably installed inside the sliding seat 4, and a spring 8 is provided between the ejector pin 7 and the sliding seat 4, one end of the ejector pin 7 passes through the outer surface of the sliding seat 4, and the end of the ejector pin 7 away from the first hydraulic cylinder 3 passes through the outer surface of the lower mold 6, and one end of the ejector pin 7 is in contact with the stopper 9.

[0034] The first hydraulic cylinder 3 uses the base 1 as a fulcrum to push the sliding seat 4, so that the sliding seat 4 moves along the direction of the guide rod 5, so that the guide rod 5 positions the lower mold 6 and the upper mold 10, so that the upper mold 10 and the lower mold 6 can be accurately molded. At the same time, when the sliding seat 4 rises, the ejector pin 7 and the stopper 9 are disengaged, so that the spring 8 pushes the ejector pin 7 back into the sliding seat 4, and then the molten metal is injected. When the molten metal is cooled, the first hydraulic cylinder 3 contracts and drives the sliding seat 4 to move downward, so that the lower mold 6 and the upper mold 10 are opened. Then, as the sliding seat 4 descends, the ejector pin 7 contacts the stopper 9 to eject the parts in the lower mold 6, so that the parts are automatically demolded after the lower mold 6 and the upper mold 10 are opened.

[0035] A pushing mechanism is arranged inside the middle support base 2. The material is pushed between the molds through the pushing mechanism. The pushing mechanism includes: a feeding barrel 16. The feeding barrel 16 is fixedly installed at one end of the middle support base 2 away from the first hydraulic cylinder 3, and the feeding barrel 16 penetrates the outer surface of the middle support base 2 and is connected to the upper mold 10.

A feeding port 17 is installed through the side surface of the feeding barrel 16, and the feeding port 17 is designed in a funnel shape and is located inside the water-absorbing fireproof cloth 15.

[0036] The funnel-shaped design of the feeding port 17 can reduce the probability of metal liquid splashing when injecting metal liquid into the feeding barrel 16. After the metal liquid enters the feeding barrel 16, it will flow downward. Then, the second hydraulic cylinder 19 pushes the pushing rod 18 to move the pushing rod 18 inside the feeding barrel 16, pushing all the metal liquid between the lower mold 6 and the upper mold 10, so that the metal liquid is pushed into the mold, and at the same time, no metal liquid remains on the inner wall of the feeding barrel 16.
