Description
Technical Field
[0001] This utility model relates to the field of casting mold application technology, and in particular to a quick-change positioning mechanism for casting molds. Background Technology
[0002] In the casting production process, mold replacement is a frequent and crucial operation. Traditional mold replacement methods typically rely on manual alignment, positioning, and fixing of the mold, which presents the following problems: positioning accuracy depends on the operator's experience, and deviations are prone to occur, leading to unstable casting quality; the replacement process is time-consuming, requiring repeated adjustments to the mold position, reducing production efficiency; traditional positioning structures are mostly rigid connections, making the mold susceptible to impact damage during installation, and while some positioning mechanisms exist in existing technologies, they generally suffer from complex structures, high maintenance costs, or insufficient positioning reliability. Therefore, this utility model proposes a rapid mold replacement positioning mechanism for castings. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a quick-change positioning mechanism for casting molds. The mechanism uses a guide component and a positioning pin to achieve quick mold alignment, reducing manual adjustment time. The positioning component and the symmetrical locking device ensure the symmetry and stability of the mold installation and prevent misalignment. At the same time, the locking component enables automated operation, reduces labor intensity, and improves production efficiency.
[0004] To solve the above-mentioned technical problems, the present invention provides a quick-change positioning mechanism for casting molds, comprising a base plate, a guide assembly bolted to the top of the base plate, a mold component slidably connected to the top of the guide assembly, a mounting base fixedly connected to the bottom of the mold component, a positioning assembly bolted to one end of the top of the base plate and engaging with the mold component, and a locking assembly bolted to the other end of the top of the base plate and engaging with one end of the mold component.
[0005] The present invention is further configured such that an L-shaped plate is bolted to one end of the bottom of the substrate.
[0006] The above technical solution facilitates the use of L-shaped plates to position and fix the entire device.
[0007] The present invention is further configured such that: the guide assembly includes a limiting block bolted to the top of the substrate, and guide rails are symmetrically bolted to the side wall of the limiting block near the end face; the bottom of the mounting base is symmetrically provided with sliding grooves near both sides, and is slidably connected to the guide rails through the sliding grooves.
[0008] The above technical solution allows the mounting base to slide stably on the guide rail via the slide groove, thereby sliding it to the corresponding position for positioning and fixation.
[0009] The present invention is further configured such that: the positioning component includes a Y-shaped frame bolted to the bottom of the base plate, a positioning pin is provided through the top of the Y-shaped frame, a guide rod is fixedly connected to the bottom of the positioning pin, a spring is wrapped around the outer wall of the guide rod, the guide rod passes through the bottom of the Y-shaped frame, and a pull block is fixedly connected to its end face.
[0010] The above technical solution utilizes the sliding of the mounting base on the guide rail, which presses against the top inclined surface of the positioning pin, thereby pressing the entire positioning pin and causing it to press against the spring at the bottom. During continuous sliding, when the pin hole on the mounting base corresponds to the positioning pin, the elasticity of the spring returns the positioning pin to its original position, allowing it to be inserted into the pin hole, thus quickly positioning the mounting base.
[0011] The present invention is further configured such that: the top of the positioning pin is inclined and inserted into the pin hole opened near the end face of the bottom of the mounting base, while the two ends of the spring are respectively pressed against the bottom of the positioning pin and the inner bottom of the Y-shaped frame.
[0012] The above technical solution facilitates stable fixation of the spring and allows for quick reset of the top positioning pin and engagement with the mounting base.
[0013] The present invention is further configured such that: the locking assembly includes a mounting plate bolted to the bottom of the base plate; the mounting plate is connected to a connecting rod threaded near the corner of its top; a cylinder is bolted to the top of the mounting plate near the center; a toothed plate is bolted to the end face of the drive rod of the cylinder; a toothed column is engaged with the top of the toothed plate; a flipping block is fixedly connected to the top of the toothed column; a biting block is fixedly connected to the side wall of the flipping block, and the biting block is connected to a biting groove opened on the end face of the mounting base.
[0014] The above technical solution involves starting the cylinder, which drives the toothed plate on the end face to move, thereby causing the meshing toothed column to rotate. This, in turn, causes the top flipping block to rotate 90 degrees, so that the biting block on the flipping block accurately bites into the inside of the biting groove, thereby locking and fixing the positioned and fixed mounting seat.
[0015] The present invention is further configured such that: the inner wall of the tooth column is interference-fitted with a rotating shaft, the end face of the rotating shaft is symmetrically fixedly connected with a side plate, and both side plates are bolted to the top of the mounting plate.
[0016] The above technical solution facilitates stable rotation of the gear column on the side plate via the rotating shaft when driven, thereby improving the stability during locking.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0028] like Figures 1-3As shown, a quick-change positioning mechanism for casting molds includes a base plate 1. An L-shaped plate 11 is bolted to one end of the bottom of the base plate 1 to facilitate the installation and fixation of the entire device using the L-shaped plate 11. A guide assembly 3 is bolted to the top of the base plate 1. The guide assembly 3 includes a limiting block 31 bolted to the top of the base plate 1. A guide rail 32 is symmetrically bolted to the side wall of the limiting block 31 near the end face. A mounting base 21 has symmetrically opened sliding grooves 23 near both sides at the bottom and is slidably connected to the guide rail 32 through the sliding grooves 23. The guide rail 32 allows the mounting base 21 to slide stably on the guide rail 32 through the sliding grooves 23, thereby sliding it to the corresponding position for positioning and fixation. A mold component 2 is slidably connected to the top of the guide assembly 3, and the mounting base 21 is fixedly connected to the bottom of the mold component 2.
[0029] like Figure 4 As shown, a positioning component 4 is bolted to one end of the top of the substrate 1, and the positioning component 4 is engaged with the mold component 2. The positioning component 4 includes a Y-shaped frame 41 bolted to the bottom of the substrate 1. A positioning pin 42 is provided through the top of the Y-shaped frame 41. The top of the positioning pin 42 is inclined and inserted into a pin hole opened near the end face of the bottom of the mounting base 21. At the same time, the two ends of the spring 44 are respectively pressed against the bottom of the positioning pin 42 and the inner bottom of the Y-shaped frame 41, which facilitates the stable fixing of the spring 44 and the quick reset of the top positioning pin 42 to engage with the mounting base 21. The bottom of the positioning pin 42 is fixedly connected to a guide rod 43. A spring 44 is wrapped around the outer wall of the guide rod 43. The guide rod 43 passes through the bottom of the Y-shaped frame 41 and a pull block 45 is fixedly connected to its end face. The mounting base 21 slides on the guide rail 32, which presses the top inclined surface of the positioning pin 42, thereby pressing the entire positioning pin 42 and pressing the spring 44 at the bottom. During continuous sliding, when the pin hole on the mounting base 21 corresponds to the positioning pin 42, the elasticity of the spring 44 resets the positioning pin 42, allowing it to be inserted into the pin hole, thus quickly positioning the mounting base 21.
[0030] like Figure 5As shown, a locking assembly 5 is bolted to the top of the substrate 1 near one end, and the locking assembly 5 engages with one end of the mold part 2. The locking assembly 5 includes a mounting plate 51 bolted to the bottom of the substrate 1. The mounting plate 51 is connected to a connecting rod 52 threaded to its top near the corner. A cylinder 53 is bolted to the top of the mounting plate 51 near the middle. A toothed plate 54 is bolted to the end face of the drive rod of the cylinder 53. A toothed column 55 is meshed with the top of the toothed plate 54. A rotating shaft 561 is interference-fitted to the inner wall of the toothed column 55. Side plates 562 are symmetrically fixed to the end face of the rotating shaft 561, and both side plates 562 are bolted to the top of the mounting plate 51 to facilitate the toothed column 55. When driven, it can rotate stably on the side plate 562 via the rotating shaft 561, improving the stability during locking. The top of the toothed column 55 is fixedly connected to the flipping block 56, and the side wall of the flipping block 56 is fixedly connected to the biting block 57. The biting block 57 is connected to the biting groove 22 opened on the end face of the mounting base 21. When the cylinder 53 is activated, its drive rod drives the toothed plate 54 on the end face to move, thereby causing the meshing toothed column 55 to rotate, which in turn causes the top flipping block 56 to rotate 90 degrees, so that the biting block 57 set on the flipping block 56 accurately bites into the inside of the biting groove 22, thereby locking and fixing the mounting base 21 after positioning and fixing.
[0031] In use, the mold part 2 is first slid on the guide rail 32 through the slide groove 23 on the mounting base 21, which presses against the top inclined surface of the positioning pin 42, thereby pressing the entire positioning pin 42 and pressing the spring 44 at the bottom. During continuous sliding, when the pin hole on the mounting base 21 corresponds to the positioning pin 42, the elasticity of the spring 44 resets the positioning pin 42, allowing it to be inserted into the pin hole, thus quickly positioning the mounting base 21. Then, the cylinder 53 is activated, and its drive rod moves the toothed plate 54 on the end face, causing the meshing toothed column 55 to rotate, which in turn causes the top flipping block 56 to rotate 90 degrees, so that the biting block 57 on the flipping block 56 accurately bites into the inside of the biting groove 22, thereby locking and fixing the positioned mounting base 21.
