The mold bottom plate 3, the side plates 4 at both ends, and the two adjacent longitudinal sliding plates 601 surround and form a molding cavity 7. An injection pipe 8 connected to the molding cavity 7 is provided on each connecting pressing plate 602; an overflow hole 9 is provided on the side end surface of the injection pipe 8 close to the connecting pressing plate 602. The sliding plate 6 is in contact with the horizontal motion driving device.

[0031] The upper end surface of the mold base 1 is provided with a molding groove 2, and a vibration component is provided on the bottom wall of the mold base 1 at a position corresponding to the molding groove 2. A fastening component is provided on the mold base 1, and the fastening component is connected to the vertical motion driving device.

[0032] The horizontal motion driving device includes a first molding base plate 10 and a first cylinder assembly 11. The mold base plate 3 is provided with the first molding base plate 10 along the length direction of the sliding plate 6; the first molding base plate 10 is provided with a first cylinder assembly 11; the first cylinder assembly 11 includes a cylinder housing and a first cylinder fixed in the cylinder housing; the piston rod of the first cylinder passes through the cylinder housing; the piston rod of the first cylinder assembly 11 contacts the connecting plate 602; the bottom end height of the piston rod is higher than the bottom end height of the connecting plate 602.

[0033] The fastening assembly includes a second molding base plate 12, an elastic buffer pad 13 and a fastening rod 14. The mold base plate 3 is provided with a second molding base plate 12 on both sides along the width direction of the sliding plate 6; each second molding base plate 12 is provided with an elastic buffer pad 13 and a fastening rod 14 stacked from bottom to top; the elastic buffer pad 13 and the fastening rod 14 are fixedly connected; the elastic buffer pad 13 is crimped onto the second molding base plate 12.

[0034] The vertical motion driving device is a second cylinder assembly 15 . The second cylinder assembly 15 includes a cylinder housing and a second cylinder fixed in the cylinder housing; a piston rod of the second cylinder passes through the cylinder housing; and the piston rod of the second cylinder assembly 15 is connected to the fastening rod 14 .

[0035] The vibration assembly includes a compression spring 16 and a vibrator 17. One end of the compression spring 16 is connected to the bottom wall of the mold bottom plate 3, and the other end is connected to the bottom wall of the molding groove 2. There are four compression springs 16, and the four compression springs 16 are distributed around the vibrator 17. The vibrator 17 is arranged on the bottom wall of the mold bottom plate 3. The vibrator 17 can be a conventional small vibrator. The compression spring 16 is in a compressed state.

[0036] A limiting rod 18 is provided on the mold base 1 at the middle of the second molding bottom plate 12 ; an elastic buffer strip 19 is provided at the lower end of the limiting rod 18 ; a certain distance is left between the lower end of the elastic buffer strip 19 and the upper end of the second molding bottom plate 12 .

[0037] Therefore, the working principle of this embodiment is specifically as follows:

[0038] In the molding stage, the elastic buffer block 13 is fastened and crimped on the second molding bottom plate 12 to firmly fix the mold base 1 and the mold body; cement mortar is injected into each molding cavity 7 from the injection pipe 8, and when cement mortar flows out of the overflow hole 9, it means that the cement mortar in each molding cavity 7 is full;

[0039] After the cement mortar fills each molding cavity 7, the second cylinder starts working, and the piston rod of the second cylinder drives the fastening rod 14 to move upward a certain distance, the elastic buffer pad 13 no longer contacts the second molding base plate 12, and the second cylinder stops working; the vibrator 17 starts working, and the mold base 1, the mold body, the first molding base plate 10, the first cylinder assembly 11, and the second molding base plate 12 move upward to contact the elastic buffer strip 19 under the elastic force of the compression spring 16; the vibrator 17 drives the mold base 1, the mold body, the first molding base plate 10, the first cylinder assembly 11, and the second molding base plate 12 to vibrate with a small amplitude. During the vibration process, the first molding base plate 10 is always located below the limit rod 18 and the elastic buffer strip 19, which plays a role of limiting, and the first molding base plate 10 is always located below the fastening assembly; during the vibration process, the density of the cement mortar block becomes more uniform, and the pore space is squeezed to reduce the pores;

[0040] After vibrating for a certain period of time (generally within 5 minutes), the vibrator 17 stops working, and the second cylinder starts working again. The piston rod of the second cylinder drives the fastening rod 14 to move downward until the elastic buffer pad 13 is pressed against the second forming bottom plate 12, and the mold base 1 and the mold body are firmly fixed, and the second cylinder stops working; the first cylinder starts working, and the piston rod of the first cylinder drives the sliding plate 6 to move until the sliding plate 6 completely slides out of the forming cavity 7, and the piston rod of the first cylinder retracts to the initial position, thereby realizing the demolding of the cement mortar block. The demolding operation is very convenient, and the cement mortar block is demolded without damage, which is convenient for subsequent testing; in the process of the sliding plate 6 sliding out, the sliding plate 6 also scrapes off the excess cement mortar on the surface of the cement mortar block to make the surface of the cement mortar block smooth, and also presses the cement mortar block to press out the pores on the surface of the cement mortar block, without the need for additional grinding operation.
