Description

Technical Field

[0001] This utility model relates to the field of demolding technology, specifically a demolding device for engineering machinery. Background Technology

[0002] During the manufacturing process of construction machinery, some components have complex structures and large dimensions. Therefore, casting is often used to manufacture these components. After casting these components using molds, demolding is required.

[0003] Chinese utility model patent application number 202222400163.1 provides a casting demolding device. In use, the device raises the bottom mold by controlling an electric push rod, and then lowers the demolding head by controlling a motor to push the casting in the mold hole of the bottom mold, thereby achieving demolding. However, in actual operation, the fixed connecting frame obstructs the bottom mold and the top of the mold hole, making it inconvenient to directly pour liquid metal into the mold hole, thus making both casting and demolding inconvenient. Therefore, an engineering machinery demolding device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an engineering machinery demolding device, including a base plate, a mold body fixedly connected to the top of the base plate, a mold hole opened on the mold body, and a demolding mechanism provided on the base plate;

[0006] The demolding mechanism includes: a guide sleeve, a fixed plate, and a mounting plate. The guide sleeve is embedded in the bottom of the base plate. A push rod is slidably connected to the inner wall of the guide sleeve. The top end of the push rod passes through the base plate and extends into the mold hole. The extended end of the push rod is fixedly connected to the top plate. The fixed plate is fixedly connected to the bottom of the base plate. A hinge arm is hinged to the front of the fixed plate. The hinge arm is arranged in an inverted "L" shape. A sliding hole one is opened on the upper front of the hinge arm. A sliding hole two is opened on the lower front of the hinge arm. A sliding rod one is fixedly connected to the lower outer wall of the push rod. A mounting plate is fixedly connected to the bottom of the base plate. An electric hydraulic cylinder is connected to the left side of the mounting plate. A connecting strip is fixedly connected to the piston end of the electric hydraulic cylinder. A sliding rod two is fixedly connected to the front of the connecting strip.

[0007] Preferably, the outer wall of the first sliding rod is slidably connected to the inner wall of the first sliding hole, and the outer wall of the second sliding rod is slidably connected to the inner wall of the second sliding hole.

[0008] Preferably, a sealing gasket is embedded in the upper part of the outer wall of the top plate, and the outer wall of the sealing gasket is in contact with the inner wall of the mold hole.

[0009] Preferably, there are several of each of the mold hole, guide sleeve, top rod, top plate, fixing plate, hinge arm, sliding hole one, sliding hole two, sliding rod one, and sliding rod two, and they are arranged at equal intervals.

[0010] Preferably, each of the push rods is provided with a cleaning mechanism, the cleaning mechanism including: a mounting ring, the mounting ring being fixedly sleeved on the upper part of the outer wall of the push rod, and a cleaning brush being adhered to the outer wall of the mounting ring, the cleaning brush being arranged in a ring shape, and the brush bristles abutting against the inner wall of the mold hole.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This engineering machinery demolding device, by activating an electric hydraulic cylinder, pushes a connecting bar to move. A sliding rod on the connecting bar slides within a sliding hole in the hinge arm, causing the hinge arm to rotate around the hinge point on the fixed plate. As the hinge arm rotates, the sliding hole moves accordingly, causing the sliding rod on the outer wall of the ejector rod to slide within the sliding hole, thereby pushing the ejector rod upwards along the guide sleeve. The top plate at the top of the ejector rod ejects the casting from the mold hole, thus enabling rapid and stable demolding of the casting from the mold. Compared to traditional demolding methods, this significantly improves demolding efficiency and avoids obstruction above the mold hole, facilitating the direct pouring of liquid metal into the mold hole. This solves the problem of inconvenient pouring during casting with traditional demolding devices, making both casting and demolding processes more convenient.

[0014] 2. This type of demolding device for engineering machinery, when the ejector rod moves up and down to perform demolding operation, the mounting ring and the cleaning brush on its outer wall clean the inner wall of the mold hole along with the movement of the ejector rod. It can effectively remove the casting materials, impurities and other residues on the inner wall of the mold hole, keep the mold hole clean, reduce the workload of manual mold cleaning, improve the service life of the mold, and also provide good mold conditions for subsequent casting work, which helps to improve the quality of castings.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0024] Please see Figure 1-4One embodiment of this utility model is: a demolding device for engineering machinery, including a base plate 1, a mold body 2 fixedly connected to the top of the base plate 1, a mold hole 3 opened on the mold body 2, and a demolding mechanism 4 provided on the base plate 1; the demolding mechanism 4 includes: a guide sleeve 41, a fixing plate 44, and a mounting plate 49. The guide sleeve 41 is embedded in the bottom of the base plate 1, and a push rod 42 is slidably connected to the inner wall of the guide sleeve 41. The top end of the push rod 42 penetrates the base plate 1 and extends into the mold hole 3. The extended end of the push rod 42 is fixedly connected to a top plate 43. A sealing gasket is embedded in the upper part of the outer wall of the top plate 43, and the outer wall of the sealing gasket is flush with the inner wall of the mold hole 3. The fitting, through the setting of the sealing gasket, effectively prevents the leakage of molten metal during the pouring of liquid metal. The fixing plate 44 is fixedly connected to the bottom of the base plate 1. The front of the fixing plate 44 is hinged with a hinge arm 45, which is set in an inverted "L" shape. A sliding hole 46 is opened on the upper front of the hinge arm 45, and a sliding hole 47 is opened on the lower front of the hinge arm 45. A sliding rod 48 is fixedly connected to the lower outer wall of the top rod 42. The outer wall of the sliding rod 48 is slidably connected to the inner wall of the sliding hole 46. The bottom of the base plate 1 is fixedly connected with a mounting plate 49. An electric hydraulic cylinder 410 is connected to the left side of the mounting plate 49. A connecting strip 411 is fixedly connected to the piston end of the 10. A slide rod 412 is fixedly connected to the front side of the connecting strip 411. The outer wall of the slide rod 412 is slidably connected to the inner wall of the slide hole 47. There are several mold holes 3, guide sleeves 41, push rods 42, top plates 43, fixing plates 44, hinge arms 45, slide holes 46 and 47, slide rods 48 and 412, which are arranged at equal intervals. By starting the electric hydraulic cylinder 410, its piston end pushes the connecting strip 411 to move. The slide rod 412 on the connecting strip 411 slides in the slide hole 47 of the hinge arm 45, causing the hinge arm 45 to rotate around the fixed... When the hinge point on the fixed plate 44 rotates and the hinge arm 45 rotates, the sliding hole 46 moves accordingly, causing the sliding rod 48 on the outer wall of the ejector rod 42 to slide within the sliding hole 46. This, in turn, pushes the ejector rod 42 upward along the guide sleeve 41. The top plate 43 at the top of the ejector rod 42 ejects the casting from the mold hole 3, thus enabling the casting to be quickly and stably removed from the mold. Compared with traditional demolding methods, this greatly improves demolding efficiency and avoids obstruction above the mold hole 3, making it convenient to directly pour liquid metal into the mold hole 3. This solves the problem of inconvenient casting during casting with traditional demolding devices, making both casting and demolding processes more convenient.

[0025] Working principle: By starting the electric hydraulic cylinder 410, its piston end pushes the connecting bar 411 to move. The second slide rod 412 on the connecting bar 411 slides in the second slide hole 47 of the hinge arm 45, causing the hinge arm 45 to rotate around the hinge point on the fixed plate 44. When the hinge arm 45 rotates, the first slide hole 46 moves accordingly, causing the first slide rod 48 on the outer wall of the ejector rod 42 to slide in the first slide hole 46, thereby pushing the ejector rod 42 to move upward along the guide sleeve 41. The top plate 43 at the top of the ejector rod 42 ejects the casting in the mold hole 3, completing the demolding.

[0026] Please see Figure 1-4 Based on the above embodiments, in another embodiment of this utility model, each ejector rod 42 is provided with a cleaning mechanism 5. The cleaning mechanism 5 includes: a mounting ring 51, which is fixedly sleeved on the upper part of the outer wall of the ejector rod 42. A cleaning brush 52 is adhered to the outer wall of the mounting ring 51. The cleaning brush 52 is arranged in a ring shape, and the bristles abut against the inner wall of the mold hole 3. When the ejector rod 42 moves up and down to perform demolding operation, the mounting ring 51 and the cleaning brush 52 on its outer wall clean the inner wall of the mold hole 3 with the movement of the ejector rod 42, which can effectively remove the casting material, impurities, etc. remaining on the inner wall of the mold hole 3, and maintain... Cleaning the mold hole 3 reduces the workload of manual mold cleaning, improves the service life of the mold, and provides good mold conditions for subsequent casting work, which helps to improve the quality of castings. The interior of the mold body 2 is hollow. A water inlet pipe 6 is fixedly connected to the upper left side of the mold body 2, and a water outlet pipe 7 is fixedly connected to the lower right side of the mold body 2. Coolant is introduced into the mold body 2 through the water inlet pipe 6, and the coolant is discharged through the water outlet pipe 7, thereby accelerating the cooling process of the casting and reducing the deformation of the mold caused by high temperature, thus improving the quality and forming effect of the casting.

[0027] Working principle: When the ejector pin 42 moves up and down to perform the demolding operation, the mounting ring 51 and the cleaning brush 52 on its outer wall clean the inner wall of the mold hole 3 along with the movement of the ejector pin 42. This effectively removes the casting materials and impurities remaining on the inner wall of the mold hole 3, keeping the mold hole 3 clean. After the molten metal is poured into the mold hole 3, coolant is introduced into the mold body 2 through the water inlet pipe 6, and the coolant is discharged through the water outlet pipe 7. This accelerates the cooling process of the casting and reduces the deformation of the mold caused by high temperature, thereby improving the quality and molding effect of the casting.

[0028] It is worth noting that the mold hole 3 and the electric hydraulic cylinder 410 in the above embodiments are common equipment in the prior art. The models used can be customized according to actual usage requirements. In addition, the power supply interface of the electrical equipment in this utility model is connected to the power supply system through a switch (not shown in the figure) and a wire (not shown in the figure) to realize its control. The circuit control, specific composition and principle involved are all prior art, which are known in the current field and are clear to those skilled in the art. Therefore, they will not be described in detail here.

[0029] This utility model provides a demolding device for engineering machinery. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
