Technical Field
[0001] This utility model relates to the field of casting mold technology, specifically a casting mold for precast beams and slabs used in highways. Background Technology
[0002] Casting molds are tools or equipment used to produce precast components. They define the shape and size of the precast components. In highway construction, casting molds are widely used to produce various precast components, including precast beams and slabs for highways, which are formed using casting molds.
[0003] For example, Chinese patent CN212859844U (A precast beam mold for highways) includes a bracket and a base. An observation window is provided on the upper part of the bracket. The lower end of the bracket is fixedly connected to the upper end of the base. A moving mechanism is fixedly connected between the inner walls of the bracket. The moving mechanism includes a ball screw, a slide bar, a T-shaped bracket, and a first motor. A stroke nut is fixedly connected to one end of the T-shaped bracket, and a slide bar ring is fixedly connected to the other end. The stroke nut is threaded onto the ball screw, and the slide bar ring is slidably connected to the slide bar. A first hydraulic telescopic rod is fixedly connected to the lower end of the T-shaped bracket, and a moving block is fixedly connected to the lower end of the first hydraulic telescopic rod. The length and width of the moving block are the same as the dimensions of the inner cavity of the base. The moving block slides within the inner cavity of the base. This technical solution solves the problem in the prior art that the precast beam mold cannot be adjusted to adapt to the length of precast beams of different lengths.
[0004] However, existing casting molds adjust dimensions using ball screw slides, which require continuous power, resulting in wasted electricity. Furthermore, when the moving end of the ball screw slide is subjected to opposing forces, positional deviations can easily occur, leading to errors in casting dimensions and affecting the size and stability of precast beams for highways. Therefore, these methods do not meet current requirements. To address this, we propose a new casting mold for precast beams for highways. Utility Model Content
[0005] The purpose of this utility model is to provide a casting mold for precast beams and slabs for highways, in order to solve the problems mentioned in the background art, which are that the existing casting molds adjust the size by means of ball screw slide rails. The ball screw slide rails need to be constantly powered, which leads to power waste. Furthermore, when the moving end of the ball screw slide rail is subjected to opposite forces, positional deviations are prone to occur, resulting in errors in the casting size, affecting the size and stability of the precast beams and slabs for highways.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a precast beam casting mold for highways, comprising: a first mold plate, a second mold plate disposed on one side of the first mold plate, an adjustment component disposed inside the space formed by merging the first mold plate and the second mold plate, connecting components disposed at both ends of the connection between the first mold plate and the second mold plate, a connecting base disposed on the lower surface of the first mold plate and the second mold plate, and a threaded fastener disposed at one end of the connecting base.
[0007] Preferably, the adjustment assembly includes a first adjustment plate, a second adjustment plate is provided on one side of the first adjustment plate, and a limiting seat is provided on the inner surface of one end of both the first adjustment plate and the second adjustment plate.
[0008] Preferably, the adjustment assembly further includes a positioning frame, one side surface of which is provided with a limiting movement groove, and the limiting seat moves along the limiting movement groove.
[0009] Preferably, the upper surface of the positioning frame is provided with an adjustment groove, and the adjustment groove is interconnected with the limiting movement groove. One side surface of one end of the first adjustment plate and the second adjustment plate is provided with an extension seat. The upper end of the extension seat is provided with a single-headed fastener. One end of the single-headed fastener passes through the extension seat and the adjustment groove in sequence and is then fixed by an external fixing nut.
[0010] Preferably, both ends of the first mold plate are provided with sleeves, the front surface of the sleeves is provided with threaded grooves, both ends of the second mold plate are provided with inserts, and multiple inserts and sleeves are provided.
[0011] Preferably, the connecting assembly includes a connecting seat and a connecting sleeve, and the connecting sleeve is located on the side surface of one end of the connecting seat and is sleeved outside the sleeve. The other side surface of one end of the connecting seat is provided with a through hole, and a fastener is inserted into one end of the through hole. The fastener is threaded and fixed to the threaded groove after passing through the through hole.
[0012] Preferably, the front surface of the connector near the other end is provided with a slot, and the insert plate is inserted along the slot, and a stabilizing plate is provided on one side surface of the other end of the connector.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model sets an adjustment component inside the space after the first mold plate and the second mold plate are combined. The adjustment component mainly includes a first adjustment plate and a second adjustment plate. Before pouring, the positions of the first adjustment plate and the second adjustment plate are adjusted according to the size of the precast beam slab, thereby realizing the adjustment of the pouring size of the precast beam slab. After adjustment, one end of the single-head fastener passes through the extension seat and the adjustment groove in sequence and is fixed by the external fixing nut, which fixes the first adjustment plate and the second adjustment plate. After being subjected to force, it is not easy to shift the position, thereby improving stability. Compared with the existing method of using ball screw slide rails for size adjustment, this method is more stable. In terms of construction, it is less prone to positional deviation and does not require constant power to maintain stability, saving energy and facilitating operation even without power. It is also less likely to have cement adhering to the ball screw slide rail during pouring, which could obstruct its movement. Maintenance costs are low. It solves the problems of existing casting molds that use ball screw slide rails for size adjustment, which require constant power supply, resulting in wasted electricity. Furthermore, when the moving end of the ball screw slide rail is subjected to opposing forces, positional deviations can easily occur, leading to errors in the pouring dimensions and affecting the dimensions and stability of precast beams and slabs used in highways.
[0015] (2) By setting connecting components at both ends of the connection between the first mold plate and the second mold plate, when installing the connecting components, the connecting sleeve is placed outside the sleeve base, the insert plate is inserted along the slot, and then one end of the fastener passes through the through hole and is threaded to the threaded groove to fix the connecting components. Since the insert plate is inserted along the slot, it has a limiting effect on the second mold plate, preventing it from separating from the first mold plate after being subjected to force, improving the stability of the connection between the first mold plate and the second mold plate, and also making it easier to replace the connecting components when damaged, thus improving flexibility.
