[0002] UHPC molding dies are tools or devices specifically designed for manufacturing ultra-high performance concrete (UHPC) products. Their function is to mold flowing or semi-flowing UHPC slurry into the desired final shape and size, and then harden and set it through a proper curing process.

[0003] A search of existing concrete molding dies revealed that patent application number 201920608856.5 discloses an adjustable curvature precast concrete molding die. Its structure is simple, enabling rapid molding of concrete products with varying curvatures, offering a wide molding range, effectively reducing the production cost of curved precast concrete, and producing aesthetically pleasing results with fewer seams. However, this concrete molding die has the following drawbacks when used in UHPC products:

[0004] Firstly, after UHPC products are formed in the mold cavity, it is not convenient to quickly eject the UHPC products from the mold cavity, which makes it difficult to demold quickly and the demolding efficiency is relatively low.

[0005] Secondly, during the concrete pouring process, it is not easy to scrape the concrete on the top of the molding mold, which will result in an uneven top of the molded UHPC product. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1, referring to Figure 1 , Figure 3 and Figure 4 A quick demolding mold for molding UHPC products includes a support frame 1, a UHPC product molding mold 2 is fixedly installed on the top outer wall of the support frame 1, and a matching ejector plate 5 is slidably connected inside the mold cavity of the UHPC product molding mold 2. A demolding driver and a top scraper are sequentially provided on the support frame 1.

[0028] Specifically, the demolding drive includes a lead screw 3, a push rod 4 threadedly connected to the lead screw 3 and fixedly connected to the outer wall of the bottom center of the ejector plate 5, a servo motor 6 fixedly installed on the outer wall of the bottom of the support frame 1, a worm gear 7 fixedly mounted on the output shaft of the servo motor 6, and a worm wheel 8 fixedly mounted on the lower part of the lead screw 3.

[0029] Furthermore, a bearing seat 9 is fixedly installed on the top outer wall of the support frame 1, and the bottom end of the lead screw 3 is connected to the inner wall of the bearing seat 9 through the bearing. The bearing seat 9 ensures the stability of the rotation of the lead screw 3. Furthermore, the worm 7 and the worm wheel 8 mesh with each other, and a limiting port adapted to the ejector rod 4 is opened at the bottom center of the UHPC product molding mold 2. The outer wall of the ejector rod 4 is slidably connected to the inner wall of the limiting port.

[0030] The working principle of this embodiment is as follows: the servo motor 6 drives the worm gear 7 to rotate, and then the worm wheel 8 meshing with the worm gear 7 drives the lead screw 3 to rotate. Then, under the limit of the limit port, the ejector rod 4 threaded to the lead screw 3 drives the ejector plate 5 to move upward continuously. This facilitates the rapid ejection of the UHPC product formed in the mold cavity, achieving the effect of rapid demolding and effectively improving the demolding efficiency.

[0031] Example 2, refer to Figure 1 , Figure 2 and Figure 5 This embodiment is an optimization based on embodiment 1. Specifically, the top scraper includes a bearing plate 10 welded to the outer wall of the rear side of the support frame 1, a drive motor 11 fixedly installed on the outer wall of the rear side of the bearing plate 10, a turntable 12, a scraper rod 16, an eccentric column 13 welded to the outer wall of the front side of the turntable 12, and a reciprocating moving frame 14 installed on the eccentric column 13.

[0032] Furthermore, the reciprocating frame 14 is provided with a guide port that matches the eccentric column 13. The eccentric column 13 is slidably connected to the guide port. A linear guide rail 17 is fixedly installed on the top outer wall of the bearing plate 10. A guide block 18 is fixedly installed on the bottom outer wall of the reciprocating frame 14. The guide block 18 is slidably connected to the linear guide rail 17. The purpose of this arrangement is to ensure that after the turntable 12 rotates, the eccentric column 13 drives the reciprocating frame 14 to reciprocate along the horizontal direction.

[0033] Furthermore, the scraper rod 16 is fixedly connected to the reciprocating moving frame 14 via the connecting rod 15. The bottom surface of the scraper rod 16 is on the same horizontal plane as the top surface of the UHPC product molding mold 2. The output shaft of the drive motor 11 passes through the upper rear side of the support plate 10. The turntable 12 and the output shaft of the drive motor 11 are coaxially fixedly connected to each other.

[0034] The working principle of this embodiment is as follows: The turntable 12 is driven to rotate by the drive motor 11. Then, the eccentric column 13 on the turntable 12 will drive the reciprocating moving frame 14 to move back and forth in the horizontal direction. The guide block 18 at the bottom will slide back and forth along the linear guide rail 17 to ensure the stability of the linear motion. Thus, the reciprocating moving frame 14 drives the scraping rod 16 to move back and forth, which facilitates the scraping of the concrete on the top of the UHPC product molding mold 2 and helps to improve the flatness of the top of the molded UHPC product.
