DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3The utility model provides a technical solution: a grouting mold for chalk production that is easy to demold, comprising a mold base 1, a molding mold 2 is fixed on the top of the mold base 1, a heating control mechanism 3 for controlling the temperature is installed on the outer side of the molding mold 2, a main control panel 4 for controlling the temperature is installed on the outer side of the mold base 1, a molding component 500 is installed between the mold base 1 and the inside of the molding mold 2, and a discharge component 600 is installed on the top of the molding mold 2; through the coordinated use of the molding mold 2, the molding component 500 and the discharge component 600 on the top of the mold base 1, demolding is convenient and the demolded chalk can be discharged at one time, so that the chalk can be demolded and discharged more conveniently during the production process, further reducing the workload of the staff, so that the production of chalk can be carried out efficiently, thereby improving the practicality of the grouting mold for chalk production.

[0024] In this embodiment, the discharge assembly 600 is a structure for facilitating the discharge of the chalk after demoulding.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the discharge assembly 600 includes a limiting frame 601 fixed to the top of the forming mold 2, two fixed plates 602 fixed to the top of the limiting frame 601, a fixed rod 603 fixed between opposite sides of the two fixed plates 602, a connecting slide 604 slidably connected to the outside of the fixed rod 603, a push plate 605 fixed to the front of the connecting slide 604, a hand-held plate 606 fixed to the top of the push plate 605, a metal patch 607 bonded to the left side of the connecting slide 604, a magnetic block 608 fixed to the right side of the left fixed plate 602, a discharge opening 609 opened on the right side of the limiting frame 601, and a discharge slide 610 fixed to the right side of the forming mold 2 and located outside the discharge opening 609.

[0026] It should be noted that the cross section of the push plate 605 is conical, and the bottom of the push plate 605 fits with the top of the forming mold 2, so that the push plate 605 can push the chalk on the top of the forming mold 2 to move.

[0027] In addition, the position of the metal patch 607 corresponds to the position of the magnetic block 608, so that the metal patch 607 can be adsorbed on the magnetic block 608, thereby facilitating the positioning. The bottom of the discharge chute 610 is tilted downward to facilitate the sliding discharge of chalk.

[0028] In this embodiment, the molding assembly 500 is a structure for drying and molding the chalk.

[0029] like Figure 1As shown, the molding assembly 500 includes a heating tube 501 which is passed through and fixed inside the molding mold 2 and controlled by the heating control mechanism 3, a grouting groove 502 which is opened on the top of the molding mold 2 and is evenly distributed, an electric push rod 503 which is fixed to the inner bottom wall of the mold base 1, a connecting plate 504 which is fixed to the output end of the electric push rod 503, four linear rods 505 which are fixed to the inner side of the mold base 1, a linear slide 506 which is slidably connected to the outer side of the linear rod 505, and a piston push rod 507 which is fixed to the top of the connecting plate 504 and is evenly distributed.

[0030] It should be noted that the mold base 1 is a square box with an opening on one side of the back. A baffle is connected to the back of the mold base 1 by screws, so that the internal structure of the mold base 1 can be set up normally. The heating control mechanism 3 is connected to the end of the heating tube 501 so that it can form an integral heating device. The principle of electric heating and temperature control are existing public technologies. The heating control mechanism 3 is a device for controlling the temperature of the heating tube 501, and the electrical components appearing in the text are all electrically connected to the main control panel 4 and the power supply. The provision of power is common knowledge in the field. The main control panel 4 can be a conventional known device for controlling a programming computer, etc., which can be realized by simple programming by technicians in this field, and they are all existing public power connection technologies, which will not be described in detail in the text.

[0031] In addition, the outer sides of the connecting plate 504 are fixedly connected to the outer sides of the four linear slides 506 , respectively, so that the connecting plate 504 can be stably moved by the electric push rod 503 under the sliding action between the four linear slides 506 and the corresponding linear rods 505 .

[0032] At the same time, the top end of the piston push rod 507 passes through the bottom of the forming mold 2 and extends to the inside of the corresponding grouting groove 502. The distance between the top of the connecting plate 504 and the bottom of the forming mold 2 is greater than the height of the grouting groove 502. When the connecting plate 504 is driven by the electric push rod 503 to be lifted to the highest height, the top end of the piston push rod 507 is located on the outside of the top of the corresponding grouting groove 502. A sliding sealing ring is fixed on the outside of the piston push rod 507, which fits the inner wall of the corresponding grouting groove 502 and plays a sealing role. This allows the piston push rod 507 to push out the chalk inside the grouting groove 502 and play a sealing role under the action of the sealing ring.

[0033] The working principle of the above embodiment is:

[0034] When producing chalk, the raw material to be formed is injected into the interior of each grouting groove 502, and the heating control mechanism 3 is used to heat the heating tube 501. The molding raw material gradually loses moisture by controlling the temperature, so that it is dried and formed, and the excess raw material on the top of the molding mold 2 is scraped away, and the electric push rod 503 is started to drive the connecting plate 504 to move upward. Under the cooperation between the linear rod 505 and the corresponding linear slide 506, the connecting plate 504 can drive each piston push rod 507 to move inside the corresponding grouting groove 502 when moving upward, so that the formed chalk can be pushed upward, so that it is moved out from the inner side of the grouting groove 502 and accumulated inside the limiting frame 601. The hand-held plate 606 is pinched and slid to the right side, so that the connecting slide 604 slides on the outside of the fixed rod 603. At the same time, the push plate 605 pushes the chalk inside the limiting frame 601 to move to the right side and is discharged into the inside of the discharge chute 610 through the discharge opening 609, and then moved to the outside to be collected, which is convenient for the demoulding and discharge of the chalk.

[0035] Compared with the prior art, the grouting mold for chalk production, which is easy to demold, is easy to demold and can discharge the demolded chalk at one time through the coordinated use of the forming mold 2, the forming component 500 and the discharge component 600 on the top of the mold base 1. Therefore, the chalk can be demolded and discharged more conveniently during the production process, further reducing the workload of the staff, so that the production of chalk can be carried out efficiently, thereby improving the practicality of the grouting mold for chalk production, and solving the problem that the existing dust-free chalk production device needs to manually take out the chalk after demolding, and its operation method is not convenient.

[0036] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
