Description

Technical Field

[0001] This utility model belongs to the field of casting technology, specifically relating to a mold for elevator rope pulleys. Background Technology

[0002] An elevator pulley is a movable pulley installed on an elevator, typically located at the top or bottom of the car or on the upper part of the counterweight frame. Its main function is to create different traction ratios by having the traction steel wire rope pass around the anti-pulley, thereby reducing the output power and torque of the traction machine, controlling the tension and position of the traction steel wire rope, and adjusting the speed and acceleration of the elevator. Patent CN220612202U discloses a sand mold for casting elevator pulleys, including an upper mold and a lower mold. The upper and lower molds are connected together by a connecting block 43 and a fixing block horizontally inserted. However, this connection method only ensures that the upper and lower molds do not detach, but cannot guarantee that the upper and lower molds are in a tight pressed state. Especially after long-term use, the upper and lower molds are not pressed tightly together, resulting in poor mold performance. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] Example: Figures 1-3 As shown, this embodiment provides a mold for elevator rope pulleys, including an upper mold 1, a lower mold 2, and a U-shaped clamping frame 3; several vertical limiting grooves 11 are formed on the outer peripheral wall of the upper mold 1, and the lower end of the vertical limiting grooves 11 passes through the lower end of the upper mold 1; several vertical limiting members 21 are fixedly arranged on the outer peripheral wall of the lower mold 2, and the vertical limiting members 21 are correspondingly engaged with the vertical limiting grooves 11 for positioning, and the vertical limiting members 21 are provided with first mounting holes 211; the U-shaped clamping frame 3 is matched and fastened to the outer peripheral wall of the upper mold 1. The two ends of the U-shaped clamping frame 3 are located on opposite sides of the upper mold 1, and the middle structure of the U-shaped clamping frame 3 is in contact with part of the upper surface of the upper mold 1; several second mounting holes 31 are opened at both opposite ends of the U-shaped clamping frame 3; the second mounting holes 31 of the U-shaped clamping frame 3 are aligned one-to-one with the second mounting holes 31 of part or all of the vertical limiting members 21 on opposite sides of the lower mold 2; the locking member 4 is used to pass through the first mounting holes 211 and the second mounting holes 31 aligned one-to-one to lock the upper mold 1 and the lower mold 2.

[0026] Through the above settings, the vertical limiting component 21 and the vertical limiting groove 11 are used for insertion and positioning to ensure that the upper mold 1 and the lower mold 2 are aligned vertically, thus playing a role in pre-positioning the upper mold 1 and the lower mold 2. The U-shaped clamping frame 3 is fastened on the upper mold 1 and locked vertically with the vertical limiting component 21 of the lower mold 2 through the locking component 4, thereby pressing and positioning the upper mold 1 and the lower mold 2 vertically. During use, it is avoided that the upper mold 1 and the lower mold 2 will move laterally relative to each other or separate vertically, thus ensuring the normal use of the mold.

[0027] In this embodiment of an elevator rope sheave mold, a positioning groove 12 is provided on the outer wall of the upper mold 1 for the U-shaped clamping frame 3 to be matched and embedded for positioning. This arrangement serves to position the U-shaped clamping frame 3, improves the installation stability of the U-shaped clamping frame 3, and facilitates quick installation of the U-shaped clamping frame 3.

[0028] In this embodiment of an elevator rope sheave mold, the U-shaped clamping frame 3 has a handle 32 for easy access to the U-shaped clamping frame 3.

[0029] In this embodiment of an elevator sheave mold, there is a gap between the vertically aligned first mounting hole 211 and the second mounting hole 31. This arrangement facilitates adjustment of the clamping force on the upper mold 1 and the lower mold 2.

[0030] In this embodiment of an elevator rope pulley mold, the U-shaped clamping frame 3 is a U-shaped rod structure. This design is simple and low-cost.

[0031] In this embodiment of an elevator sheave mold, there are several U-shaped rod structures, which are evenly distributed on the upper mold 1. This arrangement ensures uniform pressing of the upper mold 1 and the lower mold 2 by using multiple U-shaped rod structures to press them together.

[0032] In this embodiment of an elevator sheave mold, two adjacent vertical limiting members 21 are fixedly connected by a connecting rod 5. This arrangement improves the structural stability of the vertical limiting members 21.

[0033] In this embodiment of the elevator sheave mold, the connecting rod 5 has three members: two horizontal rods 51 and one inclined rod 52. One end of the inclined rod 52 is fixedly connected to one end of one of the horizontal rods 51, and the other end of the inclined rod 52 is fixedly connected to one end of the other horizontal rod 51. The two horizontal rods 51, the inclined rod 52, and two adjacent vertical limiting members 21 form two triangular stabilizing structures. This arrangement, using the triangular stabilizing structure formed by the connecting rod 5 and the vertical limiting member 21, further improves the structural strength of the vertical limiting member 21.

[0034] In this embodiment of an elevator pulley mold, the locking component 4 consists of a matching bolt and nut. This design results in a simple structure, stable and convenient installation, and low cost.

[0035] In this embodiment of the elevator sheave mold, the vertical limiting member 21 is a rod-shaped structure or a plate-shaped structure. This design simplifies the structure and reduces costs.
