Description

Technical Field

[0001] This utility model relates to the field of brick making technology, specifically a quick-release mold for making dock bricks. Background Technology

[0002] Dock bricks are special types of bricks used in ports, docks, and other heavy-duty areas, primarily for paving surfaces to support the weight of ships, cargo, and heavy equipment. Dock bricks are typically made of high-strength concrete or masonry materials, possessing excellent wear resistance, compressive strength, and frost resistance, enabling them to adapt to various climatic conditions and heavy-duty environments.

[0003] The production process of dock bricks generally includes the following steps. First, suitable raw materials are selected, mainly including cement, sand, gravel, and water. Different proportions of raw materials are prepared according to design requirements to ensure the strength and durability of the bricks. Next, the raw materials are mixed evenly to form a concrete slurry. Then, the mixed concrete is poured into brick molds, and vibration equipment is used to remove air bubbles, ensuring the density of the bricks. After pouring, the bricks need to be cured, generally through pressing and heating.

[0004] Existing demolding methods for dock bricks include manual demolding, pneumatic demolding, vibration demolding, and mechanical demolding. However, due to the inherent stickiness of the dock brick blanks, the edges tend to adhere to the mold after curing, making demolding difficult and requiring repeated demolding operations. This is especially true for irregularly shaped dock bricks, where the edges and corners are more prone to sticking to the mold, necessitating multiple vibration demolding attempts and wasting time. To address these issues, a rapid demolding mold for dock bricks is provided. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release brick-making mold for dock bricks, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release brick-making mold for wharf bricks, comprising a frame and a bottom mold;

[0007] The frame is equipped with a sliding rod and side strips. The side of the bottom mold is slidably sleeved on the sliding rod, and a first spring is sleeved on the outer wall of the sliding rod to apply a downward elastic force to the bottom mold.

[0008] Lifting mechanism;

[0009] Used to move the bottom mold upwards, the lifting mechanism disengages from the bottom mold, the bottom mold falls rapidly under the elastic force of the first spring, stops after hitting the side strip on the side of the bottom mold, and the brick blank inside the bottom mold is vibrated and quickly demolded.

[0010] As a preferred technical solution of this utility model, the bottom mold has multiple mold holes inside, and a pressure plate for pressing the brick blank inside the mold holes is slidably installed inside the frame.

[0011] As a preferred technical solution of this utility model, a telescopic plate for receiving brick blanks is slidably installed on the inner bottom surface of the bottom mold.

[0012] As a preferred technical solution of this utility model, the lifting mechanism includes a telescopic rod, a locking block, a slide rail, and a pressure block. The telescopic rod is installed on the bottom surface inside the frame, and a block is installed on the upper end of the telescopic rod. The locking block is slidably installed inside the block, and one end of the locking block extends out from one side of the block. The slide rail is fixedly installed inside the frame, and the block is slidably installed inside the slide rail. The pressure block is fixedly installed on the upper end of the slide rail groove.

[0013] As a preferred embodiment of this utility model, a second spring is installed inside the block of the telescopic rod to apply elastic force to the locking block.

[0014] As a preferred technical solution of this utility model, one end of the card block is provided with a first inclined surface, the upper end of the card block is provided with a right-angled triangular prism, and the lower end of the pressure block is provided with a second inclined surface that matches the inclined surface of the right-angled triangular prism.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses a lifting mechanism to move the bottom mold upwards. After the lifting mechanism disengages from the bottom mold, the bottom mold falls rapidly under the elastic force of the first spring and stops after hitting the edge strip on the side. The brick blank inside the bottom mold is quickly demolded by the vibration generated after the bottom mold hits the edge strip. This solves the problem that when demolding existing bricks, the edges of the bricks stick to the mold after the bricks have solidified, making them difficult to demold. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-8 This embodiment provides a quick-release brick-making mold for dock bricks, including a frame 1 and a bottom mold 2. The frame 1 is based on a brick-making machine of model QT10-15. Two side strips are fixedly installed on the bottom surface of the inner side of the frame 1. Two sliding rods 21 are also fixedly installed inside the frame 1, with the lower ends of the sliding rods 21 fixedly connected to the upper ends of the side strips. The two sides of the bottom mold 2 are slidably sleeved on the sliding rods 21. A pressure plate is also slidably installed inside the frame 1, and the pressure plate moves up and down inside the frame 1 driven by a hydraulic column. Figure 2 As shown, a sliding cavity is provided on the bottom surface of the frame 1, and a telescopic plate 11 is slidably installed in the sliding cavity. The telescopic plate 11 is also driven by a hydraulic column.

[0028] The bottom mold 2 has multiple mold holes. During use, a steel plate is placed on the telescopic plate 11. After the telescopic plate 11 moves upward, the steel plate fits against the lower end of the bottom mold 2, supporting the bottom mold 2 while sealing the area below the mold holes. Then, the injection device injects brick raw material into the mold holes of the bottom mold 2. After injection, the pressure plate moves downward, compressing the brick raw material in the mold holes. After compression, the bottom mold 2 is heated or the raw material is allowed to air dry to form a brick blank. During demolding, the telescopic plate 11 moves downward, and the brick blank in the rotating hole slides downward under its own weight, finally landing on the steel plate. At this point, the steel plate is removed, and the brick blank can be taken away for the next brick-making process (baking or drying, etc.).

[0029] However, in actual operation, it was found that the brick raw material has a certain degree of stickiness. After the bricks are dried into brick blanks, the edges of the brick blanks will stick to the mold holes of the bottom mold 2, making it difficult to demold. In order to facilitate the demolding of the brick blanks, a first spring 22 is sleeved on the outer wall of the slide rod 21, and a lifting mechanism 3 for raising the height of the bottom mold 2 is also installed in the frame 1.

[0030] The first spring 22 applies a downward elastic force to the bottom mold 2. The lifting mechanism 3 includes a telescopic rod 31, a locking block 32, a slide rail 33, and a pressure block 34. The telescopic rod 31 is installed on the bottom surface inside the frame 1 and is a hydraulic rod. A block is installed on the upper end of the output rod of the telescopic rod 31. A groove is opened on the side of the block facing the bottom mold 2. The locking block 32 is slidably installed in the groove of the block, and one end of the locking block 32 extends from the end of the groove facing the bottom mold 2. A second spring 321 is also installed in the groove of the block. The second spring 321 applies an elastic force to the locking block 32 in the direction of the bottom mold 2, causing one end of the locking block 32 to extend from the end of the groove. The slide rail 33 is fixedly installed inside the frame 1, and the block is slidably installed inside the slide rail 33, stabilizing the movement of the block through the slide rail 33. Figure 4 and Figure 6 As shown, the end of the locking block 32 facing the bottom mold 2 is provided with a first inclined surface. After the output rod of the telescopic rod 31 retracts, the first inclined surface of the locking block 32 contacts the edge of the bottom mold 2 and retracts. After the locking block 32 is located below the side of the bottom mold 2, the locking block 32 can be ejected by the elastic force of the second spring 321.

[0031] like Figure 1 As shown, when the bottom mold 2 needs to be lifted, the output rods of the telescopic rods 31 of the two lifting mechanisms 3 extend synchronously, and the locking block 32 engages with the side of the bottom mold 2, causing the bottom mold 2 to move upward. At this time, the first spring 22 is compressed. The pressure block 34 is fixedly installed on the upper end of the rail groove of the slide rail 33. The upper end of the locking block 32 is provided with a right-angled triangular prism, and the lower end of the pressure block 34 is provided with a second inclined surface that matches the inclined surface of the right-angled triangular prism. During the upward movement of the bottom mold 2, the inclined surface of the right-angled triangular prism on the locking block 32 fits against the second inclined surface of the pressure block 34. The pressure block 34 applies pressure to the locking block 32 through the right-angled triangular prism, causing the locking block 32 to retract into the sliding groove of the block, so that the locking block 32 is separated from the edge of the bottom mold 2. The elastic force of the first spring 22 and the weight of the bottom mold 2 itself cause the bottom mold 2 to fall rapidly. After hitting the edge strip at the edge of the bottom mold 2, it generates vibration. The strong vibration causes the brick blanks in the bottom mold 2 to fall synchronously and rapidly onto the steel plate, completing the rapid demolding.

[0032] Compared to existing methods for demolding dock bricks, this new method utilizes the downward force of the first spring 22 and the weight of the bottom mold 2 to rapidly descend, generating strong vibrations upon impact with the edge strip, thus facilitating rapid demolding of the brick blank within the mold. This design effectively leverages gravity and the elasticity of the first spring 22, breaking away from traditional demolding methods that rely on push rods or manual tapping. This allows the bottom mold 2 to fall quickly during demolding, minimizing the time required for demolding. This rapid descent mechanism not only improves production efficiency but also reduces the curing time of the brick within the bottom mold 2, thereby enhancing overall production capacity. The strong vibrations generated when the edge of the bottom mold 2 impacts the edge strip help reduce the adhesion between the brick blank and the bottom mold 2. Through vibration, the brick blank can separate from the bottom mold 2 more quickly. The uniform circumferential vibration causes all parts of the brick blank to simultaneously detach from the mold cavity, effectively avoiding the edge damage problems caused by traditional single-point ejection and reducing the risk of brick damage during demolding. This efficient demolding method ensures the integrity and surface quality of the brick, reducing the scrap rate caused by improper demolding. Furthermore, this design features a relatively simple structure. Traditional demolding methods often require complex pneumatic systems, resulting in high maintenance and operating costs. This design, through a simple lifting structure, gravity, and spring mechanism, reduces the complexity and failure rate of the equipment, thereby improving the reliability of the mold.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
