Description

Technical Field

[0001] This utility model relates to the field of demolding technology, and in particular to an automatic demolding machine. Background Technology

[0002] A mold is a tool used to shape various products. Through specific structural design and processing techniques, it shapes raw materials (such as cement and concrete) into the required shape and size under certain pressure and temperature conditions. In cement block production, molds are usually made of metal (such as steel or aluminum alloy) or plastic.

[0003] In the field of mold manufacturing and product molding, demolding is one of the key links in the production process. Traditional demolding methods mostly rely on manual operation. The traditional method of demolding by manually hammering or disassembling the mold is labor-intensive, inefficient, and can easily damage the mold and the product. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide an automatic demolding machine to solve the current problem that demolding is achieved by manual hammering or manual disassembly of the mold, which is labor-intensive, inefficient, and prone to damage to the mold and product.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An automatic demolding machine includes a base, with positioning slide shafts fixedly installed at the four corners of the base. A lifting assembly for falling along the positioning slide shafts is provided above the base, and a mold limiting component for fixing the mold is provided between the lifting assembly and the base.

[0008] Above the lifting assembly is a first cone driven by a driving device, and below the first cone and at the top of the lifting assembly is a self-falling assembly for docking. Above the first cone and at the top of the lifting assembly is an excitation assembly corresponding to the self-falling assembly.

[0009] The driving device includes a device base fixed to one end of the positioning slide shaft away from the base and distributed parallel to the base. A hydraulic push rod is fixedly installed on the device base, and the piston rod of the hydraulic push rod passes through one end of the device base and is fixedly connected to the first cone.

[0010] As an improved technical solution, the lifting assembly includes main beams symmetrically distributed above the base, secondary beams linearly arranged between the main beams, and symmetrically distributed sliding shaft limiting sleeves corresponding to the positioning sliding shafts fixedly installed at both ends of the secondary beams. An annular shaft seat adapted to the first cone is also fixedly installed on the top of the secondary beams.

[0011] As an improved technical solution, the self-falling assembly includes hinge seats distributed in a ring on the outside of the annular shaft seat. Each hinge seat is movably connected to a gripper body for gripping the first cone. One end of each gripper body extending into the hinge seat is fixedly installed with a connecting shaft for limiting the deflection of the gripper body. The end of the gripper body away from the connecting shaft is also provided with a gripper activation end adapted to the first cone.

[0012] As an improved technical solution, an arc-shaped through hole is provided between the connecting shaft and the gripper activation end, and on the gripper body. An annular spring is provided on the outer side of the annular shaft seat, which is adapted to the arc-shaped through hole and is used for the gripper body to reset.

[0013] As an improved technical solution, the excitation assembly includes height limiting seats distributed parallel to each other below the equipment base, and each of the four corners of the height limiting seat is provided with a lead screw connected by a nut. The lead screw extends through one end of the height limiting seat into the equipment base, and a second cone corresponding to the annular shaft seat is fixedly installed on the side of the height limiting seat near the first cone. When the first cone is in the docking state driven by the hydraulic push rod, the second cone is located in the annular shaft seat. When the second cone is in the demolding state, the first cone is located in the annular shaft seat.

[0014] As an improved technical solution, the mold limiting component includes base columns fixed at both ends of the main beam and distributed perpendicularly to the main beam. The end of the base column away from the main beam is fixedly installed with a clamping plate distributed parallel to the base, and the top of the clamping plate is provided with an auxiliary rod for limiting the movement of the mold.

[0015] As an improved technical solution, the four corners of the base are also fixedly equipped with support shafts that are compatible with the positioning slide shaft and correspond to the slide shaft limiting sleeve.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model achieves reliable gripping and release of the mold by connecting the gripper body in the self-falling component with the first cone, and ensures the accuracy of the action and reset by the connecting shaft and the ring spring, thereby effectively reducing labor intensity and improving demolding efficiency.

[0018] 2. This utility model achieves automatic demolding of the mold by triggering the second cone in the excitation component and the self-falling component, and adjusts the height of the second cone by the lead screw to adapt to the demolding requirements of different molds.

[0019] 3. This utility model achieves smooth movement of the lifting component by sliding the sliding shaft limit sleeve along the positioning sliding shaft, and limits the maximum descent height of the lifting component by the support shaft, thus ensuring the safety of demolding.

[0020] 4. This utility model achieves stable fixation of the mold during the demolding process through the clamping plate and auxiliary rod in the mold limiting component, ensuring that the mold will not move or fall off during the molding and demolding process. Attached Figure Description

[0034] like Figures 1 to 6As shown in the figure, this embodiment provides an automatic demolding machine, which includes a base 1. Positioning slide shafts 2 are fixedly installed at the four corners of the base 1. A lifting assembly 3 for falling along the positioning slide shafts 2 is provided above the base 1. A mold limiting member 4 for fixing the mold is provided between the lifting assembly 3 and the base 1. A first cone 6 driven by a driving device 5 is also provided above the lifting assembly 3. A falling assembly 7 for docking is provided below the first cone 6 and at the top of the lifting assembly 3. An excitation assembly 8 corresponding to the falling assembly 7 is provided above the first cone 6 and at the top of the lifting assembly 3. The driving device 5 includes a device base 501 fixed to the end of the positioning slide shaft 2 away from the base 1 and distributed parallel to the base 1. The device base 501 is fixed with... A hydraulic push rod 502 is fixedly installed, and the piston rod of the hydraulic push rod 502 passes through one end of the equipment base 501 and is fixedly connected to the first cone 6. The base 1 serves as the basic support structure of the entire demolding machine, bearing the weight of all components and ensuring the stability of the entire equipment. The positioning slide shaft 2 provides a guide for the vertical movement of the lifting assembly 3, ensuring its smooth lifting. The lifting assembly 3 carries the mold and realizes its vertical lifting for demolding operation. The mold limiting component 4 fixes the mold to prevent it from moving or falling off during demolding. The drive device 5 provides power to the first cone 6 and realizes the lifting movement of the lifting assembly 3 during docking. The first cone 6 serves as the upper structure of the lifting assembly 3, cooperating with the self-falling assembly 7 and the excitation assembly 8 to realize the gripping and demolding of the mold.

[0035] The lifting assembly 3 includes main beams 301 symmetrically distributed above the base 1, secondary beams 302 linearly arranged between the main beams 301, and symmetrically distributed sliding shaft limiting sleeves 303 corresponding to the positioning sliding shafts 2 fixedly installed at both ends of the secondary beams 302. An annular bearing seat 304 adapted to the first cone 6 is also fixedly installed on the top of the secondary beams 302. The sliding shaft limiting sleeves 303 allow the lifting assembly 3 to move along the axial direction of the positioning sliding shafts 2 when it moves.

[0036] The self-falling assembly 7 includes hinge seats 701 arranged in a ring around the outer side of the annular shaft seat 304. Each hinge seat 701 is movably connected to a gripper body 702 for gripping the first cone 6. One end of the gripper body 702 extending into the hinge seat 701 is fixedly mounted with a connecting shaft 703 for limiting the deflection of the gripper body 702. The end of the gripper body 702 away from the connecting shaft 703 is also provided with a gripper activation end 704 adapted to the first cone 6. The hinge seats 701 are arranged in a ring around the outer side of the annular shaft seat 304 to provide the mounting position for the gripper body 702. The gripper body 702 is movably connected to the hinge seat 701 for gripping or releasing the first cone 6. The connecting shaft 703 limits the deflection of the gripper body 702 to ensure the stability of its movement. The gripper activation end 704 cooperates with the first cone 6 to realize the gripping or releasing action of the gripper body 702.

[0037] An arc-shaped through hole 705 is provided between the connecting shaft 703 and the gripper actuation end 704 and on the gripper body 702. An annular spring 706 is provided on the outer side of the annular shaft seat 304, which is adapted to the arc-shaped through hole 705 and is used for resetting the gripper body 702. The arc-shaped through hole 705 is located on the gripper body 702 and cooperates with the annular spring 706 to realize the resetting of the gripper. The annular spring 706 is installed on the outer side of the annular shaft seat 304 and is used for resetting the gripper body 702.

[0038] The triggering component 8 includes a height limiting seat 801 parallel to the equipment base 501. Each of the four corners of the height limiting seat 801 is provided with a lead screw 802 connected by a nut. One end of the lead screw 802 passes through the height limiting seat 801 and extends into the equipment base 501. A second cone 803 corresponding to the annular shaft seat 304 is also fixedly installed on the side of the height limiting seat 801 near the first cone 6. When driven by the hydraulic push rod 502, the first cone 6 is located in the annular shaft seat 304 when in the docking state, and the second cone 803 is located in the annular shaft seat 304 when in the demolding state. The height limiting seat 801 is installed parallel to the equipment base 501 to provide an installation platform. The lead screw 802 is fixed to the height limiting seat 801 by a nut and is used to adjust the position of the second cone 803. The second cone 803 cooperates with the annular shaft seat 304 to trigger the action of the self-falling component 7.

[0039] The mold limiting component 4 includes base columns 401 fixed at both ends of the main beam 301 and distributed perpendicularly to the main beam 301. A clamping plate 402 distributed parallel to the base 1 is fixedly installed at the end of the base column 401 away from the main beam 301. The top of the clamping plate 402 is provided with an auxiliary rod 403 for limiting the movement of the mold. The base column 401 is vertically fixed at both ends of the main beam 301 to provide support. The clamping plate 402 is connected to the base column 401 and is parallel to the base 1 for clamping the mold. The auxiliary rod 403 is installed on the top of the clamping plate 402 to further limit the movement of the mold.

[0040] The four corners of the base 1 are also fixedly installed with support shafts 9 that are compatible with the positioning slide shaft 2 and correspond to the slide shaft limit sleeve 303. The support shafts 9 correspond to the positioning slide shaft 2, which enhances the stability of the entire lifting assembly 3 and limits the maximum descent height of the lifting assembly 3.

[0041] In use, the mold containing the concrete block is fixed to the lifting assembly 3 by the mold limiting member 4. The clamping plate 402 and auxiliary rod 403 in the mold limiting member 4 ensure that the mold will not move or fall off during demolding. The mold remains stable during the molding process. During demolding, the hydraulic push rod 502 in the drive device 5 is activated, pushing the first cone 6 connected to its piston rod downward until the first cone 6 enters the annular shaft seat 304 and docks with the self-falling assembly 7. The gripper body 702 in the self-falling assembly 7 cooperates with the first cone 6 through the gripper activation end 704. The deflection of the main body 702 is limited by the coupling 703 to ensure the stability of the movement. The annular spring 706 resets the gripper body 702 through the arc-shaped through hole 705. After the docking is completely completed, the piston rod of the hydraulic push rod 502 drives the first cone 6 to rise, so that the secondary beam 302 and the main beam 301 in the lifting assembly 3 connected to the annular shaft seat 304 rise synchronously with the first cone 6. The sliding shaft limiting sleeve 303 in the lifting assembly 3 slides along the positioning sliding shaft 2 to ensure the smooth movement of the lifting assembly 3. The base column 401 in the mold limiting part 4 drives the connected clamping plate 402 and The mold fixed on the auxiliary rod 403 rises synchronously, thus completing the mold gripping. As the first cone 6 continues to rise, the second cone 803 fixed on the height limiting seat 801 contacts the gripper activation end 704 in the self-falling assembly 7, causing the gripper body 702 to deflect outward, disengaging the first cone 6 connected to the piston rod of the hydraulic push rod 502. The height of the second cone 803 on the height limiting seat 801 is adjusted by the lead screw 802 on the height limiting seat 801, thereby adjusting the height of the lifting assembly 3 when it falls. The first cone 6 disengages from the annular shaft seat 304, and the lifting assembly loses its tension. 3. The sliding shaft limit sleeve 303 slides downward along the positioning sliding shaft 2, and drives the mold on the mold limit part 4 to fall rapidly. When the sliding shaft limit sleeve 303 contacts the support shaft 9, the falling stops. The impact of the falling causes the concrete block in the mold to fall onto the base 1 through the gap between the auxiliary rod 403 and the clamping plate 402, thus completing the demolding of the mold. A buffer such as a tire can be placed on the base 1 to reduce the impact of the concrete block on the base 1, thereby reducing the damage to the concrete block. The mold and the cement block are separated by the self-falling impact, and after separation, they are output through the conveying platform to realize the next process.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
