DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0022] See also Figure 1 The utility model provides a technical solution: a mold for deep-sea corrosion-resistant aluminum-magnesium alloy castings, comprising: a lower mold base 1 and an upper mold base 3, a positioning rod 2 is installed on the top of the lower mold base 1, and the upper mold base 3 is installed on the top of the positioning rod 2.

[0023] A pressure rod 22 is connected through the top of the lower die base 1, and a telescopic block 4 is arranged at the bottom of the pressure rod 22 through an inclined surface. A movable spring 5 is installed between the telescopic block 4 and the groove of the lower die base 1, a wedge block 6 is arranged at the bottom of the telescopic block 4, and a movable block 7 is arranged at the bottom of the wedge block 6. A pull rod 8 is connected through one side of the telescopic block 4, and a rubber block 9 is installed between the bottom of the telescopic block 4 and the groove of the lower die base 1. A push rod 10 is sleeved on one end of the telescopic block 4, and a return spring 11 is installed between the push rod 10 and the groove of the lower die base 1. The top of the push rod 10 is connected to a top plate 12, and the telescopic block 4 forms a telescopic structure between the movable spring 5 and the groove of the lower die base 1.

[0024] During specific implementation, the mold for deep-sea corrosion-resistant aluminum-magnesium alloy castings can use a cylinder to push the upper die seat 3 to move downward along the positioning rod 2 during the processing of corrosion-resistant aluminum-magnesium alloy castings, so that the upper die seat 3 and the lower die seat 1 are tightly fitted. At the same time, during the movement of the upper die seat 3 toward the lower die seat 1, the upper die seat 3 will squeeze the pressure rod 22 on the top of the lower die seat 1, and the pressure rod 22 will move into the groove of the lower die seat 1 under the squeezing. Since the ends of the pressure rod 22 and the telescopic block 4 that are close to each other are both inclined structures, the pressure rod 22 will pull the telescopic block 4 to move to one side through the inclined surface and squeeze the movable spring 5 on one side, and the other end of the telescopic block 4 will move out of the groove of the top rod 10, and the telescopic block 4 will drive the wedge When the wedge block 6 moves to one side, the wedge block 6 will also squeeze the movable block 7 through the inclined surface, so that the movable block 7 shrinks to the bottom of the lower die base 1 and squeezes the rubber block 9. When the wedge block 6 moves to one side of the movable block 7, the movable block 7 is not squeezed by the wedge block 6, and the movable block 7 will be reset by the rubber block 9 and move to one side of the wedge block 6. At this time, the telescopic block 4 can be limited. When the upper die base 3 moves upward, the aluminum-magnesium alloy casting in the lower die base 1 is not squeezed by the upper die base 3. At this time, the top plate 12 will be reset by the ejector rod 10 and the reset spring 11, thereby driving the top plate 12 to move upward and eject the aluminum-magnesium alloy casting from the lower die base 1, so that the user can quickly take out the aluminum-magnesium alloy casting from the lower die base 1.

[0025] Then the top plate 12 can be squeezed downward again, and the reset spring 11 can be stretched through the top rod 10. At the same time, the pull rod 8 is pulled so that the movable block 7 does not limit the wedge block 6. At this time, the telescopic block 4 will be reset by the movable spring 5 and inserted into the groove on one side of the top rod 10, thereby limiting the top plate 12 and facilitating subsequent demoulding.

[0026] See also Figure 1 , Figure 3 and Figure 4 It can be seen that when the upper die base 3 is separated from the lower die base 1, the ejector rod 10 and the ejector plate 12 can eject the aluminum-magnesium alloy casting from the top of the lower die base 1, thereby facilitating the user to quickly take out the corrosion-resistant aluminum-magnesium alloy casting.

[0027] A mounting frame 13 is installed at the bottom of the lower die base 1 through a groove, a circulating pipe 14 is installed inside the mounting frame 13, a circulating pump 15 is connected in the middle of the circulating pipe 14, a cooling fan 16 is connected on one side of the circulating pipe 14, a mounting plate 17 is installed at the bottom of the mounting frame 13, a clamping rod 18 is connected through the middle of the mounting plate 17, a telescopic spring 19 is installed between the clamping rod 18 and the groove of the mounting plate 17, a bump 20 is installed on one side of the clamping rod 18, a connecting rod 21 is connected between the two groups of clamping rods 18, and the bump 20 is inserted into the groove at the bottom of the lower die base 1 through a size matching the bump 20.

[0028] During specific implementation, when using the mold for deep-sea corrosion-resistant aluminum-magnesium alloy castings, the connecting rod 21 can be pulled to one side, and the connecting rod 21 will drive the clamping rod 18 to move to one side and squeeze the telescopic spring 19 in the groove of the mounting plate 17. At the same time, the clamping rod 18 moves to one side, which will cause the protrusion 20 to move out of the groove at the bottom of the lower die base 1. Without the limitation of the protrusion 20, the mounting plate 17 can be removed from the bottom of the lower die base 1. At this time, the mounting frame 13 can be connected to the groove at the bottom of the lower die base 1. The circulating pump 15 can drive the coolant in the circulating pipe 14 to circulate continuously. The coolant can continuously take away the heat in the aluminum-magnesium alloy casting, thereby quickly cooling the aluminum-magnesium alloy casting. When the coolant circulates to one side of the cooling fan 16, the fan can quickly dissipate the heat in the coolant to the outside of the circulating pipe 14, and the heat will be discharged through the heat dissipation holes of the lower die base 1, thereby quickly cooling the aluminum-magnesium alloy casting.

[0029] See also Figure 1 , Figure 2 and Figure 5 It can be seen that when in use, the mounting frame 13 can be docked into the groove at the bottom of the lower die base 1, and the aluminum-magnesium alloy casting can be quickly cooled through the circulation pipe 14 and the cooling fan 16, so that the aluminum-magnesium alloy casting can be quickly and conveniently processed subsequently.

[0030] To sum up: when using the mold for deep-sea corrosion-resistant aluminum-magnesium alloy castings, the aluminum-magnesium alloy casting raw material can be injected into the lower mold base 1, and then the upper mold base 3 is connected to the cylinder, and the upper mold base 3 is pushed downward along the positioning rod 2 by the cylinder, so that the upper mold base 3 and the lower mold base 1 are tightly fitted, and with the cooperation of the upper mold base 3 and the lower mold base 1, a formed aluminum-magnesium alloy casting can be obtained. This is the use feature of the mold for deep-sea corrosion-resistant aluminum-magnesium alloy castings.
