Description

Technical Field

[0001] This utility model relates to the field of curbstone production technology, specifically a curbstone blank forming mold. Background Technology

[0002] Curbstones are strip-shaped objects made of stone or concrete, used as boundary stones along the edges of roads. They are also called curb stones, roadside stones, or curb stones. A molding die is a specialized tool used to create the curbstone blank. It shapes raw materials such as concrete into a curbstone prototype that meets design requirements through specific shapes and structures.

[0003] During use, existing curbstone blank forming molds may produce curbstone blanks with inconsistent width specifications due to varying usage environments. Some forming molds can adjust the mold size by adjusting the connection position between the side plates. Typically, the side plates are connected by bolts. During adjustment, multiple bolts need to be removed and installed using tools, and then the side plates need to be moved one by one to adjust their positions. This cumbersome operation reduces the convenience of using the mold. Furthermore, since the bolts need to connect with corresponding threaded holes, and there are gaps between the threaded holes, the adjustment of the mold side plates is restricted, making it difficult to accurately adjust the mold width to the required specifications. This can easily lead to dimensional deviations, thereby reducing the production quality of the curbstone blanks. Utility Model Content

[0004] The purpose of this utility model is to provide a curbstone blank forming mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a curbstone blank forming mold, comprising a base plate, a first side plate fixedly connected to the top of the base plate, and a second side plate slidably connected to the top of the base plate, and further comprising:

[0006] An adjustment mechanism for quickly adjusting mold size is provided on the outer side of the first side plate and the second side plate. The adjustment mechanism includes a housing, a threaded sleeve, a transmission rod, and a connecting seat. The housing is fixed on the outer side of the first side plate, the threaded sleeve is provided on the inner side of the housing, the transmission rod rotates on the inner side of the threaded sleeve, and the connecting seat is fixed on the outer side of the second side plate.

[0007] A positioning mechanism for improving the flexibility of mold adjustment is provided on the outer side of the first side plate and the second side plate. The positioning mechanism includes a guide rail, a connecting frame and a positioning component. The guide rail is fixed to the top of the first side plate, the connecting frame is fixed to the top of the second side plate and the positioning component is provided on the inner side of the connecting frame.

[0008] Preferably, the adjustment mechanism further includes a rotating component, a reference component, and a sliding component. The rotating component is disposed on the inner side of the housing, the reference component is disposed on the outer side of the second side plate, and the sliding component is disposed on the outer side of the first side plate.

[0009] Preferably, the rotating assembly includes a first screw that rotates inside the housing, one end of the first screw being fixedly connected to a handle, and the outer side of the first screw being threadedly connected to the inner wall of the threaded sleeve.

[0010] Preferably, the reference component includes a scale fixed to the top of the second side plate, and a pointer is fixedly connected to the top of the first side plate.

[0011] Preferably, the positioning mechanism further includes a limiting component and a second screw, the limiting component being disposed on the inner side of the guide rail and the second screw being disposed on the outer side of the limiting component.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes the rotation of the first screw to move the threaded sleeve parallel to its axial direction, simultaneously moving one end of the transmission rod. The transmission rod rotates as a whole, and due to the change in the connection angle, its other end pushes the connecting seat to move, thus moving and adjusting the second side plate. This alters the inner dimensions of the second side plate relative to the first side plate, eliminating the need to move each mold side plate individually. The operation is simple, time-efficient, and improves the ease of mold use. Furthermore, the locking block, attached to the top of the guide rail, gradually tightens with the handle, creating a clamping force between the locking block and the sliding block. This interaction locks the first and second side plates together on the outside of the guide rail, fixing them in place. This eliminates the need for bolts and threaded holes to connect the side plates, allowing for flexible movement to the set position without dimensional deviations, thereby improving the production quality of the curbstone blank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4As shown, a curbstone blank forming mold includes a base plate 1, which serves as the basic support structure for the entire mold, bearing the weight and pressure of the mold as a whole and during concrete pouring; a first side plate 2 is fixedly connected to the top of the base plate 1, and a second side plate 3 is slidably connected to the top of the base plate 1, which cooperates with the first side plate 2 to form the forming space of the curbstone blank, and its position is adjustable. The internal dimensions of the mold can be changed by moving the second side plate 3; it also includes an adjustment mechanism 4 for quickly adjusting the mold size, which is set on the outside of the first side plate 2 and the second side plate 3. The adjustment mechanism 4 includes a housing 41, a threaded sleeve 43, a transmission rod 44, and a connecting seat 45. The housing 41 is fixed to the outer side of the first side plate 2, the threaded sleeve 43 is disposed on the inner side of the housing 41, the transmission rod 44 rotates on the inner side of the threaded sleeve 43, and the connecting seat 45 is fixed to the outer side of the second side plate 3, with its inner side rotatably connected to the other end of the transmission rod 44. When the threaded sleeve 43 moves, the transmission rod 44 rotates, and its other end pushes the connecting seat 45, thereby driving the second side plate 3 to move. The adjustment mechanism 4 also includes a rotating assembly 42, a reference assembly 46, and a sliding assembly 47. The rotating assembly 42 is located inside the housing 41, the reference assembly 46 is located outside the second side plate 3, and the sliding assembly 47 is located outside the first side plate 2. The sliding assembly 47 consists of a guide rod, a slide block, a transmission rod 44, and a connecting seat 45. When the second side plate 3 moves, the connecting seat 45 slides along the outside of the guide rod via the transmission rod 44, thereby improving the stability of the second side plate 3 during movement. The rotating assembly 42 includes a first screw 421 that rotates inside the housing 41. One end of the first screw 421 is fixedly connected to a handle 422. The outer side of a screw 421 is threadedly connected to the inner wall of a threaded sleeve 43. The screw 421 can be rotated by a handle 422. When the screw 421 rotates, it drives the threaded sleeve 43 to move parallel to its axis. The reference assembly 46 includes a scale 461 fixed to the top of the second side plate 3. A pointer 462 is fixedly connected to the top of the first side plate 2. When the second side plate 3 moves, the pointer 462 at one end of the first side plate 2 is used as a reference to indicate the direction on the scale 461. The distance that the second side plate 3 needs to move is determined according to the width specification that the mold needs to be adjusted.

[0023] A positioning mechanism 5 for improving mold adjustment flexibility is disposed on the outer side of the first side plate 2 and the second side plate 3. The positioning mechanism 5 includes a guide rail 51, a connecting frame 52, and a positioning assembly 55. The guide rail 51 is fixed to the top of the first side plate 2 and provides a guide rail for the movement of the second side plate 3. The connecting frame 52 is fixed to the top of the second side plate 3, and the positioning assembly 55 is disposed on the inner side of the connecting frame 52. The positioning mechanism 5 also includes a limiting assembly 53 and a second screw 54. The limiting assembly 53 is disposed on the inner side of the guide rail 51, and the second screw 54 is disposed on the outer side of the limiting assembly 53. The limiting assembly 53 includes a guide rail formed on the inner wall of the guide rail 51. The inner wall of the guide groove 531 is slidably connected to a sliding block 532. The top of the sliding block 532 is fixedly connected to one end of the second screw 54. When the sliding block 532 moves with the connecting frame 52, the sliding block 532 will slide along the inner side of the guide groove 531 to guide the movement path of the connecting frame 52 and make the second side plate 3 move according to a predetermined trajectory. The positioning component 55 includes a locking block 551 threadedly connected to the outside of the second screw 54. A handle 552 is fixedly connected to the outside of the locking block 551. When the handle 552 is rotated, it will move the locking block 551 up and down along the axial direction of the second screw 54.

[0024] Working principle: When adjusting the size of the mold during use, first turn the handle 422 to transmit kinetic energy to the first screw 421, causing the threaded sleeve 43 to move parallel along its axis, and simultaneously moving one end of the transmission rod 44. At this time, the transmission rod 44 rotates as a whole. Due to the change in the connection angle, its other end will push the connecting seat 45 to move, moving and adjusting the second side plate 3, changing its inner dimension relative to the first side plate 2. The pointer 462 is used as a reference on the scale 461 to improve the accuracy of the adjustment. After the adjustment is completed, first turn the handle 552 to move downward along the outside of the second screw 54, and drive the locking block 551 to move accordingly. When the locking block 551 is in contact with the top of the guide rail 51, as the handle 552 is gradually tightened, the locking block 551 and the sliding block 532 form a clamping force, which can interact to lock the outside of the guide rail 51, so that the connecting frame 52 enters a fixed state, and the first side plate 2 and the second side plate 3 can be fixed.
