Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy casting processing equipment, and in particular to an aluminum alloy casting forming mold. Background Technology

[0002] Aluminum alloy casting molds are tools used in the aluminum alloy casting process to help form the desired shape from molten aluminum alloy. Traditional molds typically consist of two parts, upper and lower, which are usually hoisted open for easy operation, maintenance, and casting removal. The lower part falls rapidly to the ground due to gravity, causing the mold to open quickly. This operation, due to the high pneumatic pressure inside the mold, and the frequent rapid opening, can easily lead to excessive wear on mold components (such as springs and sliders), affecting the mold's lifespan. Simultaneously, the heavy impact of the lower mold falling to the ground can easily damage or deform the mold, especially in precision molds. Utility Model Content

[0003] The purpose of this invention is to address the problem that when traditional molds are hoisted and opened, the bottom mold quickly falls due to gravity, causing the mold to open rapidly. This operation not only affects the service life of the mold but also easily leads to damage or deformation. Therefore, this invention proposes an aluminum alloy casting mold.

[0004] The technical solution of this utility model is as follows: an aluminum alloy casting forming mold, including a lower mold and an upper mold, and further including: a pair of connecting plates fixedly connected to the outer wall of the lower mold, each of the connecting plates being provided with a first buffer mechanism to reduce the impact force when the upper mold falls to the ground; and a second buffer mechanism provided on the first buffer mechanism to support the separation of the lower mold and the upper mold.

[0005] Optionally, the first buffer mechanism includes a sliding sleeve fixedly connected to the outer wall of the connecting plate. The bottom end of each sliding sleeve is fixedly connected to a bottom sleeve. A damping rod is slidably connected inside the sliding sleeve. The bottom end of each damping rod is fixedly connected to a buffer base. A buffer spring is movably sleeved at one end of the damping rod near the buffer base. One end of the buffer spring is fixedly connected to the bottom sleeve, and the other end of the buffer spring is fixedly connected to the buffer base.

[0006] Optionally, the second buffer mechanism includes a pair of sleeves fixedly sleeved on the end of the damping rod away from the buffer base, and the upper mold is provided with a telescopic mechanism that locks the sleeves and fixes the end of the damping rod.

[0007] Optionally, the telescopic mechanism includes a pair of telescopic grooves formed on the upper mold. A cylinder is fixedly connected inside each telescopic groove. A sliding block is fixedly connected to the piston rod of the cylinder. A U-shaped groove for locking the sleeve block is formed at the end of the sliding block away from the piston rod of the cylinder.

[0008] Optionally, a pair of extension rods are fixedly connected to the outer walls of both sides of the lower mold and the upper mold.

[0009] Optionally, a buffer pad is fixedly connected to the bottom of each buffer base.

[0010] Optionally, each of the connecting plates is provided with a plurality of fixing bolts to fix the connecting plate to the outer wall of the lower mold.

[0011] Optionally, the pair of connecting plates, telescopic grooves, cylinders and sliding blocks are all symmetrically arranged with the extension rod as the center.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes the cooperation of a lower mold, an upper mold, a connecting plate, a first buffer mechanism, and a second buffer mechanism to allow the upper and lower modules on the mold to open slowly. This helps reduce uneven stress and prevents uneven deformation of components within the mold. Simultaneously, when a module falls under its own weight, the automatically cooperating buffer mechanism effectively absorbs the impact force, reducing the probability of damage and extending the mold's service life.

[0024] Example

[0025] like Figures 1 to 3As shown, the present invention proposes an aluminum alloy casting forming mold, including a lower mold 1 and an upper mold 2. A pair of extension rods 3 are fixedly connected to the outer walls of both sides of the lower mold 1 and the upper mold 2. The extension rods 3 are for easy attachment by ropes of hoisting equipment. Multiple fixing bolts 124 are fixedly connected to a pair of connecting plates 121 on the outer wall of the lower mold 1 to secure the connecting plates 121 to the outer wall of the lower mold 1.

[0026] Among them, such as Figures 1 to 2 As shown, each connecting plate 121 is equipped with a first buffer mechanism to reduce the impact force when the upper mold 2 falls to the ground. The first buffer mechanism includes a sliding sleeve 122 fixedly connected to the outer wall of the connecting plate 121. The bottom end of each sliding sleeve 122 is fixedly connected to a bottom sleeve 125. A damping rod 123 is slidably connected inside the sliding sleeve 122. The damping rod 123 is a mechanical device used to control vibration and impact in a motion system. Its main function is to absorb energy in motion through resistance, reducing vibration, impact, or the impact of vibration on equipment or structure. It is often used in fields where it is necessary to slow down the movement or vibration of objects.

[0027] In addition, such as Figure 2 As shown, each damping rod 123 has a buffer base 127 fixedly connected to its bottom end, and a buffer pad 129 is fixedly connected to the bottom of each buffer base 127. The buffer pad 129 is made of rubber. A buffer spring 126 is also movably sleeved on one end of the damping rod 123 near the buffer base 127. The buffer spring 126 causes the second buffer mechanism to automatically reset and also provides a buffering function. One end of the buffer spring 126 is fixedly connected to the bottom sleeve 125, and the other end of the buffer spring 126 is fixedly connected to the buffer base 127.

[0028] Furthermore, such as Figure 1 and Figure 3 As shown, a second buffer mechanism is provided on the first buffer mechanism to support the separation of the lower mold 1 and the upper mold 2. The second buffer mechanism includes a pair of sleeve blocks 128 fixedly sleeved on the end of the damping rod 123 away from the buffer base 127. The upper mold 2 is provided with a telescopic mechanism that locks the sleeve blocks 128 and fixes the end of the damping rod 123. The telescopic mechanism includes a pair of telescopic grooves 21 opened on the upper mold 2. A cylinder 22 is fixedly connected inside each telescopic groove 21. A sliding block 23 is fixedly connected to the piston rod of the cylinder 22. A U-shaped groove 24 is opened at the end of the sliding block 23 away from the piston rod of the cylinder 22 to lock the sleeve block 128. The U-shaped groove 24 is a telescopic rod that locks the damping rod 123, and the U-shaped groove 24 is clamped and locked by the pair of sleeve blocks 128. The pair of connecting plates 121, telescopic grooves 21, cylinders 22 and sliding blocks 23 are all symmetrically arranged with the extension rod 3 as the center.

[0029] In this embodiment, when an aluminum alloy casting mold is needed, simply place the bottom of the lower mold 1 on the ground and press it down so that the bottom of the buffer base 127 is at the same level as the lower surface of the lower mold 1. Then, connect and install the upper mold 2 to the lower mold 1. Simultaneously, activate the cylinder 22 inside the telescopic groove 21. The piston rod of the cylinder 22 pushes the corresponding sliding block 23 to slide outwards from the upper mold 2 until the U-shaped groove 24 at the end of the sliding block 23 is engaged in a pair of sleeve blocks 128. At this point, the pressed lower mold 1 can be released. The bottom of the buffer base 127 and the bottom of the lower mold 1 are now at the same level and locked. When opening the lower mold 1 and upper mold 2, by lifting a pair of extended rods 3 on the upper mold 2, the lower mold 1 can fall downwards under gravity. Then, by having the end of the damping rod 123 engaged in the U-shaped groove 24, the damping rod 123 can slowly extend and retract, thus achieving a slow opening between the lower mold 1 and the upper mold 2. Finally, when it is necessary to completely separate the lower mold 1 from the bottom of the upper mold 2, simply activate the cylinder 22 in the telescopic groove 21 simultaneously. This causes the piston rod of the cylinder 22 to drive the sliding block 23 to fully retract into the telescopic groove 21. Immediately afterward, the damping rod 123 is no longer stuck, and the lower mold 1 will fall downward under the action of gravity. However, before the lower mold 1 hits the ground, the damping rod 123, through the elastic thrust of the buffer spring 126, causes the bottom surface of the buffer base 127 to exceed the bottom surface of the lower mold 1, thus ensuring that the bottom of the buffer base 127 contacts the ground first. At the same time, the sliding of the damping rod 123 within the sliding support 122 and the extension and retraction of the buffer spring 126 further reduce the impact force of the lower mold 1 falling to the ground.
