The center position of the second disc 3 is fixedly connected with a motor, the motor drives the second disc 3 to rotate around the vertical axis thereof, so as to rotate the corresponding matching butt-joint structure on the second disc 3 to butt-joint with the second through hole on the first disc 1, at this time, as shown in fig. 6, the first side edge of the second through hole 12 is in seamless butt-joint with the first fixing plate 32 on the matching butt-joint structure, the second side edge 14 is in seamless butt-joint with the second fixing plate 33 on the L-shaped groove surface, the first side edge 13 and the first fixing plate 32 are positioned on the same straight line, the third side edge 15 is parallel to the second fixing plate 33, the magnet on the third fixing plate 34 faces the second side edge 14, the third baffle plate 21 moves towards the first side edge 13 under the action of the magnet 36 until being attached to the magnet 36, and thus a first baffle plate 16, The first fixing plate 32, the second baffle plate 17, the third baffle plate 21 and the fourth baffle plate 35 form a hollow square mold.
In this embodiment, the radius of the second disc 3 is smaller than the radius of the first through hole 11, and the first non-bonded edge of the third fixing plate 34 parallel to the second fixing plate 33 extends to the edge of the first through hole 11, so that the L-shaped groove surface 31 formed on the second disc 3 can support the motor to drive the second disc 3 to rotate smoothly, and the first non-bonded edge of the third fixing plate 34 is prevented from being clamped by the first through hole 11 during rotation. The other ends of the first fixing plate 32 and the second fixing plate 33 extend to be connected with the hole edge of the first through hole 11, wherein the other end of the first fixing plate 32 extends to be connected with the hole edge of the first through hole 11 because the radius of the second disc 3 is smaller than that of the first through hole 11, so that the gap part between the second disc 3 and the first through hole 11 can be compensated, and the integrity of the whole periphery of the mold is ensured; the other end of the second fixing plate 33 extends to contact with the edge of the first through hole 11, so as to ensure the stability of the magnet 36 when it is attracted to the third baffle and moves horizontally. A sliding groove corresponding to the inner sliding groove of the groove edge corresponding to the square groove 18 can be further arranged on the second fixing plate 33, so that the first sliding plate slides out of the square groove and then continues to slide in the sliding groove of the second fixing plate 33. When the third baffle 21 in the second side edge 14 is engaged with the magnet 36, part of the first sliding plate 20 is still clamped in the two sliding grooves 19.
When only one second through hole 12 is provided in the first disc 1, since the shape of the second through hole 12 is fixed, therefore, in order to realize the switching of a plurality of moulds with different sizes, a plurality of identical L-shaped groove surfaces 31 are arranged on the second disc 3, the notches of the L-shaped groove surfaces are arranged along the clockwise direction, and aiming at the matching butt joint structure arranged on each L-shaped groove surface 31, on the premise of ensuring that the first non-attaching edge on the third fixing plate 34 in each matching butt joint structure extends to be connected with the hole edge of the first through hole 11, the lengths of the first non-attaching edges of the third fixing plates 34 in each matching butt joint structure are different, the motor drives the second disc 3 to rotate, the corresponding matching butt joint structure is butt jointed with the second through hole 12 on the first disc 1, thereby adjusting the length and width of the hollow square mold surrounded by the first baffle 16, the first fixing plate 32, the second baffle 17, the third baffle 21 and the fourth baffle 35.
As shown in fig. 7, in order to ensure that the first non-contact edge of the third fixing plate 34 in each matching and abutting structure extends to meet the hole edge of the first through hole 11, the length of the third fixing plate 34 inevitably decreases as the length of the first non-contact edge of the third fixing plate 34 increases, and the horizontal length of the first fixing plate 32 correspondingly used for enclosing one side of the mold increases, when the first fixing plate 32 in the matching and abutting structure abuts against the first side 13 of the second through hole 12 in the first disk 1, the length of the side of the enclosed mold where the first side 13 and the first fixing plate 32 are located increases. That is, when only one second through hole 12 is provided on the first disk 1, the length and width of the enclosed mold can be increased or decreased simultaneously by adjusting the matching abutting structure abutting against the second through hole 12.
In addition, the invention can also comprise a controller, and after receiving the length and width requirements of the corresponding die, the controller controls the motor to rotate so as to drive the corresponding matching butt joint structure on the second disc 3 to rotate to butt joint with the second through hole 12 on the first disc 1. When the device is used, a user inputs the required length and width of the mold to a controller, the length and width of the mold can be one of the lengths and widths of the molds which can be formed by the device, and after the controller receives the length and width requirement, the controller controls the motor to rotate so as to drive the corresponding matching butt joint structure on the second disc 3 to rotate to butt joint with the second through hole 12 on the first disc 1. When different matching butt joint structures are switched to be in butt joint with the second through hole, the motor drives the second circular disc to rotate along the direction from the first side edge to the second side edge (for example, the clockwise direction in fig. 6), so that when the concrete brick of the specification completes mass production, and the mass production of the concrete brick of the next specification is started, as shown in fig. 6, when the second circular disc 3 rotates along the clockwise direction, the magnet 36 can push the first sliding plate to slide towards the square groove 18 until the first sliding plate completely slides into the square groove 18, so that the next matching butt joint structure can be conveniently in butt joint with the second through hole 12.
When the third baffle 21 is attached to the magnet 36, part of the first sliding plate 20 is still clamped in the two sliding grooves 19, thereby ensuring the stability of the forming die. The lower ends of the first baffle plate 16, the first fixing plate 32, the second baffle plate 17, the third baffle plate 21 and the fourth baffle plate 35 are positioned on the same horizontal plane, the height between the lower ends of the first baffle plate 16, the first fixing plate 32, the second baffle plate 17, the third baffle plate 21 and the fourth baffle plate 35 and the lower end of the second disc 3 is used as the height of a formed mould, and when concrete bricks are produced, corresponding amount of concrete can be input into the mould according to actual conditions, so that the concrete bricks with corresponding heights can be formed under the condition that the length and the width of the mould are constant.
According to the embodiment, the first disc and the second disc are designed, so that automatic switching of a plurality of moulds with different sizes can be realized, and the length and width of the formed mould can be adjusted in a wide range.
Although the above embodiment can realize automatic switching of molds with different sizes, it can only realize simultaneous increase or decrease of the length and width of the mold, in order to realize adjustment of the corresponding width or length of the mold individually under the condition of a certain length or width of the mold, the first disk 1 is provided with a plurality of second through holes 12, the lengths of the first side 13 and the second side 14 of each second through hole 12 are different, the lengths of the third sides 15 are the same, after each second through hole 12 is butted with corresponding different matching butting structures, for each second through hole 12, the sum of the lengths of the first side 13 of the second through hole 12 and the first fixing plate 32 of the corresponding matching butting structure is subtracted by the length of the second non-butting side of the corresponding third fixing plate 34, so as to obtain the maximum value of the long side of the mold that can be enclosed in the patent, wherein the length of the first side 13 of each second through hole 12 is gradually increased, the shorter the length of the first non-attached side of the third fixing plate 34 in the mating structure corresponding to the second through hole 12 with the larger first side 13 (i.e., the smaller the difference obtained by subtracting the length of the second non-attached side of the third fixing plate 34 from the length of the first fixing plate 32 in the mating structure). Since the length of the first non-contact side of the third fixing plate 34 in the matching butt joint structure is longer and correspondingly the length of the second non-contact side of the third fixing plate 34 is subtracted from the length of the first fixing plate 32 in order to ensure that the first non-contact side of the third fixing plate 34 parallel to the second fixing plate 33 extends to contact with the hole side of the first through hole 11, the larger the difference is, as can be seen from fig. 7, when the difference is increased by a set distance, the length increase distance of the first non-contact side of the third fixing plate 34 is correspondingly greater, that is, when the length and width of the enclosed mold are adjusted by the matching butt joint structure, the adjustable unit distance of the width of the mold is greater, and the adjustable unit distance of the length of the mold is extremely short.
According to the invention, the plurality of second through holes are formed in the first disc, so that the lengths of the first side edge and the second side edge of each second through hole are different, the length of the third side edge is the same, and after each second through hole is respectively butted with the corresponding different matched butting structures, for each second through hole, the maximum value of the long edge of the mold which can be enclosed is obtained by subtracting the length of the second non-joint edge of the corresponding third fixing plate from the sum of the lengths of the first side edge of the second through hole and the first fixing plate of the corresponding matched butting structure, so that the adjustment of the corresponding width or length of the mold can be independently realized under the condition that the length or width of the mold is constant, and the adjustable unit distance of the length of the mold can be improved. It should be noted that: for each second through hole 12, a connecting line between a first point of the second through hole 12 and the center of the first disk 1 is taken as a first connecting line of the second through hole 12, the distance between the first connecting line of each second through hole 12 and the first side 13 thereof is equal, and the second side 14 of each second through hole 12 is located on the clockwise side of the first side 13 thereof.
For an L-shaped groove surface on the second disc 3, two groove surfaces of the L-shaped groove surface respectively extend vertically downward to form a first fixing plate and a fourth baffle plate, the first fixing plate and the fourth baffle plate respectively extend to the hole sides of the first through holes 11 in the corresponding directions to be connected, the first fixing plate and the fourth baffle plate form a matching butt joint structure, when one of the second through holes 12 on the first disc 1 is in butt joint with the matching butt joint structure, the free end of the first fixing plate is in seamless butt joint with the first side edge 13 on the second through hole 12, the fourth baffle plate is parallel to the third side edge 15 of the second through hole 12, and the free end of the fourth baffle plate is in seamless joint with the second side edge 14 of the second through hole 12, so that a hollow square mold surrounded by the first baffle plate, the first fixing plate, the second baffle plate, the third baffle plate and the fourth baffle plate is formed.
In addition, the shape of each L-shaped groove surface on the first disc 1 can be the same, so that the length and width adjusting range and the unit adjusting length of the die can be adjusted. In order to take out the concrete bricks from the mould after the concrete bricks are formed, the motor can also be connected with an electric telescopic rod which can stretch up and down, and after the concrete bricks are formed, the electric telescopic rod is extended upwards so that the concrete bricks in the mould are moved out from the lower part of the mould.
