Description

Technical Field

[0001] This utility model relates to the field of building material production equipment technology, and in particular to a block production mold. Background Technology

[0002] Currently, many goods require forklift loading before transportation. To facilitate forklift insertion, goods are typically placed on pallets, usually with a wooden frame and space for forklift insertion. These wooden pallets are widely used worldwide. After unloading, the pallets are often discarded or reused by the buyer, rarely returned to the seller or shipper. These wooden pallets are usually expensive, with the cost typically borne by the shipper. For low-priced, low-profit goods, the cost of using pallets is very high, increasing sales and transportation costs. To address this, we have invented a new type of support block. By placing it under goods, it supports them and facilitates forklift handling after stacking. The block is made of gypsum and cast in one piece. The bottom and sides of the block have grooves for securing straps. However, there is currently no dedicated equipment for producing this type of block. Therefore, we have designed a mold specifically for its production and applied for a patent for protection. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pad block production mold that can produce pad blocks with grooves on the bottom and sides, with a reasonable structure, high production efficiency, stable operation, and long service life.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a block production mold, comprising a mold body fixed on a frame, the mold body having multiple casting cavities, a bottom template that can move up and down within the casting cavity at the bottom of the casting cavity, the side of the bottom template being in sealed contact with the inner wall of the casting cavity, a long strip-shaped bottom protrusion being provided on the upper surface of the bottom template along the length direction, the bottom protrusion enabling the bottom of the block cast in the mold to form a through groove along the length direction, the side walls at both ends of the casting cavity having vertical long strip-shaped side protrusions, the contact portions between the two ends of the bottom template and the two end side walls of the casting cavity having transition portions, the side of the transition portion contacting the side wall of the casting cavity matching the surface shape of the side wall of the casting cavity, the side of the transition portion connecting with the upper surface of the bottom template being a concave arc surface extending upward to contact the side wall of the casting cavity, the bottom protrusion extending on the arc surface and contacting the surface of the side protrusion, and a push rod being provided at the bottom of the bottom template to push the bottom template to move up and down within the casting cavity.

[0005] Furthermore, the upper opening of the mold body is provided with a scraper mechanism for scraping off excess slurry. The scraper mechanism includes two slide plates on both sides of the mold body on the frame. The bottom of the slide plates is slidably connected to the frame through dovetail slide rails. A crossbeam is connected between the two slide rails. The two ends of the crossbeam are fixed on the slide plates and moved by the slide plates. A scraper is fixed on the crossbeam, and the lower edge of the scraper is not lower than the upper surface of the mold body.

[0006] Furthermore, the frame is provided with a synchronization mechanism, which includes a synchronization shaft mounted on the frame via bearings, synchronization gears fixed at both ends of the synchronization shaft, and a downward-facing lower wing surface on the outer side of the slide plate, with a rack fixed at the lower edge of the lower wing surface that can mesh with the synchronization gears.

[0007] Furthermore, a bidirectional hydraulic cylinder is fixed on both sides of the frame. The piston rod of the bidirectional hydraulic cylinder passes through the cylinder body and is sealed to the inner wall of the opening at both ends of the cylinder body. A piston is fixed on the piston rod and is sealed to the inner wall of the cylinder body. The piston divides the cylinder body into two oil chambers, left and right. The cylinder body is provided with two oil holes that communicate with the two oil chambers respectively. The ends of the two piston rods are fixed to both ends of the frame. The cylinder body of the bidirectional hydraulic cylinder is fixed on the slide plate. The two oil chambers of the bidirectional hydraulic cylinder have one oil inlet and one oil outlet, driving the cylinder body to move left and right. The cylinder body drives the slide plate to move, thereby driving the crossbeam to move.

[0008] Furthermore, the lower part of the frame is provided with a power device that pushes the bottom template up and down, and the power device is connected to the push rod.

[0009] In use, the bottom template is placed at the bottom of the mold body. The mixed slurry is poured into the casting cavity inside the mold body. After the slurry has partially solidified, a scraper moves along the length of the mold body to remove excess slurry and create a flat surface on the upper surface of the spacer block. After the slurry has solidified, the power unit pushes the bottom template upwards from the bottom of the mold body, pushing the solidified block out of the mold. After the spacer block is transported away, the power unit pulls the bottom template back to the bottom of the mold.

[0010] The beneficial effects of this utility model are as follows: By setting bottom protrusions on the bottom template inside the mold body and side protrusions on the two end side walls inside the casting cavity, bottom grooves and side grooves are formed on the pad to accommodate the binding strap and facilitate positioning and protection of the binding strap; the bottom template has transition parts at both ends so that the two ends of the bottom surface of the pad form an arc-shaped transition angle, so that the bottom groove and side groove form an arc-shaped transition part. The production mold structure of this utility model is reasonable, with high production efficiency, stable operation and long service life. Attached Figure Description

The side of the bottom template 3 is in sealed sliding contact with the inner wall of the casting cavity 13. An elongated bottom protrusion 4 is provided along the length of the upper surface of the bottom template 3. The bottom protrusion 4 allows the bottom of the spacer block cast in the mold to form a through groove along the length. Vertical grooves are provided on the side walls at both ends of the casting cavity 13. The long strip-shaped side protrusion 5, the two ends of the bottom template 3 are provided with transition parts 6 at the contact parts with the two end side walls of the casting cavity 13, the side of the transition part 6 that contacts the side wall of the casting cavity 13 matches the surface shape of the side wall of the casting cavity 13, the side of the transition part 6 that connects with the upper surface of the bottom template 3 is a concave arc surface and extends upward to contact the side wall of the casting cavity 13, the bottom protrusion 4 extends on the arc surface and contacts the surface of the side protrusion 5, and the bottom of the bottom template 3 is provided with a push rod 12 that can push the bottom template 3 to move up and down in the casting cavity 13.

[0021] A scraper mechanism for scraping off excess slurry is provided at the opening at the top of the mold body 2. The scraper mechanism includes two sliding plates 7 on both sides of the mold body 2 on the frame 1. The bottom of the sliding plates 7 is slidably connected to the frame via dovetail slide rails 8. Specifically, the dovetail slide rails 8 are fixed on the frame, and the bottom of the sliding plates 7 is fixed with sliders that cooperate with the dovetail slide rails 8. A crossbeam 17 is connected between the two slide rails. The two ends of the crossbeam 17 are fixed on the sliding plates 7 and are moved by the sliding plates 7. A scraper 10 is fixed on the crossbeam 17. When the scraper 10 is made of a material with small deformation (such as metal), its lower edge is slightly higher than the upper edge of the casting cavity of the mold body. If the scraper 10 is made of a material with a certain deformation (such as plastic sheet), the lower edge of the scraper 10 can be aligned with the upper edge of the casting cavity 13 of the mold body 2.

[0022] The frame 1 is equipped with a synchronization mechanism, which includes a synchronization shaft 14 mounted on the frame 1 via bearings. Synchronization gears 15 are fixed at both ends of the synchronization shaft 14. The outer side of the slide plate 7 is provided with a downward-facing lower wing surface 16. A rack 18 that can mesh with the synchronization gear 15 is fixed at the lower edge of the lower wing surface 16.

[0023] A bidirectional hydraulic cylinder 19 is fixed on both sides of the frame. The piston rod 22 of the bidirectional hydraulic cylinder 19 passes through the cylinder body 20 and is sealed to the inner wall of the opening at both ends of the cylinder body 20. A piston 21 is fixed on the piston rod 22. The piston 21 is sealed to the inner wall of the cylinder body 20 and slides. The piston 21 divides the cylinder body 20 into two oil chambers, left and right. The cylinder body 20 is provided with two oil nozzles 23 that communicate with the two oil chambers respectively. The ends of the two piston rods 22 are fixed to the two ends of the frame 1 respectively. The cylinder body 20 of the bidirectional hydraulic cylinder 19 is fixed on the slide plate 7. The two oil chambers of the bidirectional hydraulic cylinder 19 have one oil inlet and one oil outlet, which drives the cylinder body to move to the left or right. The cylinder body 20 drives the slide plate 7 to move, thereby driving the crossbeam 17 to move.

[0024] The lower part of the frame 1 is equipped with a power device to push the bottom template 3 to move up and down. Specifically, the power device is a hydraulic cylinder located at the lower part of the frame 1 to push the bottom template 3 to move up and down. The piston rod of the hydraulic cylinder is connected to a push plate 11, and the push plate 11 is connected to the push rods 12 at the bottom of all the bottom templates 3.

[0025] In use, the bottom template 3 is initially located at the bottom of the mold body 2. The mixed slurry is poured into the mold body 2. After the slurry has partially solidified, the scraper 10 moves horizontally along the length of the mold body 2 under the push of the cylinder of the bidirectional hydraulic cylinder 19, scraping off excess slurry and flattening the upper surface of the pad. Then, the two oil chambers of the bidirectional hydraulic cylinder 19 switch between oil inlet and outlet, pushing the cylinder 20 to move in the opposite direction and causing the scraper 10 to return to its original position. The synchronous shaft 14, synchronous gear 15, and rack 18 work together to ensure the synchronous movement of the two bidirectional hydraulic cylinders and the slide plate 7. After the slurry solidifies, the push plate 11 is pushed upward by the hydraulic cylinder and pushes the bottom template 3 upward from the bottom of the mold body 2 through the push rod 12, pushing the solidified pad out of the casting cavity 13. After the pad is transferred away, the bottom template 3 is pulled back to the bottom of the mold body 2, ready for the slurry to be poured in again.
