Specifically, the discharge mechanism 4 includes a discharge assembly 41 and a drive assembly 42. The discharge assembly 41 is slidably arranged in the discharge port 13 and meshedly connected with the drive assembly 42. The drive assembly 42 is arranged on the mold box 1; the discharge mechanism 4 plays a role in facilitating the demoulding of the concrete component.

[0028] In this embodiment, refer to Figure 2 and Figure 4 The unloading assembly 41 includes a unloading plate 411, two U-shaped slides 412 relatively arranged on both sides of the unloading port 13, a rack 413 and a return spring 414. The unloading plate 411 is slidably arranged in the unloading port 13, and a slider 415 is arranged on both sides thereof. The unloading plate 411 is slidably connected with the U-shaped slide 412 through the slider 415, and a return spring 414 is arranged between the lower end of the slider 415 and the mold box 1. The rack 413 is vertically arranged on one side of the unloading plate 411 and is meshed with the driving assembly 42; during specific operation, the driving assembly 42 rotates to drive the rack 413 to move upward, thereby driving the unloading plate 411 to move upward, and when the driving assembly 42 rotates to a certain angle, the rack 413 is disengaged from the driving assembly 42, so that the unloading plate 411 is reset under the action of the return spring 414, that is, the unloading plate 411 generates a downward thrust acting on the concrete component, thereby facilitating the separation of the concrete component from the forming plate 23 and completing the demoulding process.

[0029] Specifically, the driving assembly 42 includes a motor 421, a support frame 422 and a fan gear 423. The motor 421 is arranged on the mold box 1 through the support frame 422, and its output end is connected to the fan gear 423, and the fan gear 423 is meshingly connected with the rack 413; when the motor 421 rotates, the fan gear 423 can drive the rack 413 to move upward. When the fan gear 423 rotates to a certain angle, the fan gear 423 disengages from the rack 413, so that the unloading plate 411 generates a downward thrust under the action of the reset spring 414.

[0030] In this embodiment, refer to Figure 1 A limit ring 5 is provided on the outer side of the forming plate 23 in the mold box 1; the limit ring 5 serves to limit the forming plate 23 so as to restrict its movement in the forming area formed between the feed port 11 and the discharge port 12; the size of the discharge port 12 can be determined according to the specifications of the concrete components to be prepared, so as to facilitate the subsequent recovery of the concrete components under the action of the unloading mechanism 4.

[0032] The working principle of this utility model:

[0033] The utility model provides a prefabricated concrete component manufacturing mold, which includes the following steps when used:

[0034] In the first step, appropriate concrete raw materials are selected according to the required concrete component specifications and introduced through the feed port 11. The forming plates 23 of the two forming mechanisms 2 are driven by their corresponding hydraulic cylinders 22 to squeeze the concrete raw materials inward to form them;

[0035] In the second step, when the concrete component is formed, the two forming plates 23 clamp it and push it to the discharge port 12;

[0036] In the third step, the motor 421 rotates to drive the sector gear 423 to rotate, and the sector gear 423 can drive the rack 413 to move upward. When the sector gear 423 rotates to a certain angle, the sector gear 423 is separated from the rack 413, and the unloading plate 411 generates a downward thrust on the concrete component under the action of the reset spring 414, completing the demoulding of the concrete component and the forming plate 23, and then the concrete component can be discharged from the discharge port 12 for recovery.

[0037] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
