Description

Technical Field

[0001] The present application relates to the technical field of blind paving brick molds, and in particular to a new blind paving brick mold. Background Art

[0002] Currently, most of the tactile paving bricks on the market are made of glazed materials, and the production process mainly relies on plastic molds. Traditional plastic molds usually produce one tactile paving brick at a time. Although this production method is simple and easy, it is inefficient under the requirements of large-scale production and rapid laying. With the acceleration of urbanization, the demand for high-quality and high-efficiency tactile paving bricks is increasing, which puts higher requirements on existing production technology.

[0003] There are two main traditional methods: one is single-piece mold production, and the other is multi-piece mold combination production. The advantage of single-piece mold production is that the mold structure is simple and easy to maintain and replace, but the production efficiency is low and it is not suitable for mass production. Multi-piece mold combination production combines multiple mold units together to complete the production of multiple blind paving bricks at one time, but this method has complex mold design and high cost, and is prone to precision errors in actual operation, resulting in unstable product quality.

[0004] The main problem with single-piece mold production is low production efficiency, which makes it difficult to meet the needs of large-scale production. The problem with the combined production of multiple molds is that the mold design is complex, the cost is high, and it is prone to wear and deformation after repeated use, resulting in a decline in product quality. Therefore, how to improve production efficiency while ensuring product quality has become a technical problem that needs to be solved urgently.

[0005] For this reason, the present application proposes a novel blind paving brick mould. Utility Model Content

Due to the improvement in production efficiency, more products can be produced per unit time, reducing unit costs and improving product quality. Through precise mold design and automated production processes, the size consistency and surface quality of each blind paving brick are ensured, thereby improving the market competitiveness of the product and greatly improving the practicality of the device.

[0007] In order to achieve the above objectives, this application adopts the following technical solutions:

[0010] By coating a layer of Teflon coating on the surface of the mold, the anti-sticking property is improved, which facilitates demoulding and thus improves the practicality of the device.

Each positioning post is fixedly connected to the four corners of the bottom of the upper mold, and a positioning hole is opened inside the four corners of the lower mold, and each positioning post extends into the interior of the positioning hole.

[0012] The positioning mechanisms are arranged at the four corners of the main mold frame to ensure that the sub-mold units remain precisely aligned during mold closing and opening, thereby improving the practicality of the device.

[0013] As a preferred embodiment, a buffer mechanism is provided between the upper die and the lower die, and the buffer mechanism includes an elastic gasket, and two elastic gaskets are respectively provided on the mating surfaces of the upper die and the lower die;

[0014] By adding an elastic gasket between the upper mold and the lower mold of the sub-mold unit, it is used to absorb the impact force when the mold is closed, thereby extending the service life of the mold and improving the practicality of the device.

[0015] As a preferred embodiment, a monitoring mechanism is provided inside the main mold frame, and the monitoring mechanism includes temperature sensors, each of which is provided around the main mold frame;

[0016] By adding temperature sensors around the main mold frame, the mold temperature is monitored in real time, and the heating and cooling speeds are adjusted through the control system to further improve the molding quality, thereby enhancing the practicality of the device.

[0017] As a preferred embodiment, a vibration mechanism is provided at the bottom of the main mold frame, and the vibration mechanism includes a high-frequency vibrator, and the high-frequency vibrator is fixedly connected to the bottom of the lower mold;

[0032] Reference Figure 1-4 A monitoring mechanism 6 is provided inside the main mold frame 1. The monitoring mechanism 6 includes temperature sensors 61. Each temperature sensor 61 is respectively provided on the four sides of the main mold frame 1. By adding temperature sensors 61 on the four sides of the main mold frame 1, the mold temperature is monitored in real time, and the heating and cooling speeds are adjusted through the control system to further improve the molding quality, thereby enhancing the practicality of the device.

[0033] Reference Figure 1-4A vibration mechanism 7 is provided at the bottom of the main mold frame 1, and the vibration mechanism 7 includes a high-frequency vibrator 71, which is fixedly connected to the bottom of the lower mold 22; by adding a high-frequency vibrator 71 at the bottom of the main mold frame 1, high-frequency vibration is used to help the plastic fully fill the mold cavity, reduce the generation of bubbles and voids, and thus improve the practicality of the device.

[0034] Working principle: When working, first place the main mold frame 1 on the workbench of the injection molding machine, and press the main mold frame 1 through the hydraulic system to ensure a good seal. Then, the injection molding machine injects the molten plastic into the four sub-mold units 2 in the main mold frame 1, and fills the mold cavity with high pressure. After the injection is completed, it is cooled for a certain period of time to solidify the plastic into shape. Then, the electric cylinder 231 drives the demoulding mechanism 23 to push the lower mold 22 up and eject the formed blind paving bricks from the mold. Finally, the blind paving bricks are manually taken out to complete a production cycle. The whole process has a high degree of automation and significantly improves production efficiency. Regarding the operating steps and precautions, place the main mold frame 1 Place the frame 1 on the workbench of the injection molding machine, ensure that the positioning device is aligned with the positioning point of the injection molding machine, start the hydraulic system, press the main mold frame 1, check whether the seal is in good condition, start the injection molding machine, and inject the molten plastic into the four sub-mold units 2 in the main mold frame 1. Set the injection pressure to 100 MPa and the injection time to 10 seconds. Turn off the injection molding machine and start the cooling process. The cooling time is 30 seconds to ensure that the plastic is completely solidified. Start the cylinder to push the lower mold 22 up and push the formed tactile bricks out of the mold. Manually remove the tactile bricks, clean the remaining plastic fragments in the mold, and check the quality of the tactile bricks to ensure that the surface is smooth, the size is consistent, and there are no obvious defects.

[0035] The mold includes a main mold frame 1, four sub-mold units 2 and a positioning mechanism 4. The main mold frame 1 is a rectangular frame structure with four evenly distributed sub-mold units 2 inside. Each sub-mold unit 2 includes an upper mold 21, a lower mold 22 and a demoulding mechanism 23. The upper mold 21 and the lower mold 22 are both made of stainless steel and the surface is finely polished to ensure that the surface of the blind paving brick is smooth and flat after molding. The demoulding mechanism 23 is driven by an electric cylinder 231 and is located at the bottom of the main mold frame 1. It is connected to the lower mold 22 through a connecting rod 3 to realize the automatic demoulding function. The positioning mechanism 4 is set at the four corners of the main mold frame 1 to ensure that the sub-mold unit 2 remains accurately aligned during the mold closing and opening process. The mold is tightened by a hydraulic system to ensure that the mold is well sealed during the injection molding process to prevent overflow. By adding temperature sensors 61 around the main mold frame 1, the mold temperature is monitored in real time, and the heating and cooling speeds are adjusted through the control system to further improve the molding quality. In addition, by adding a high-frequency vibrator 71 at the bottom of the main mold frame 1, high-frequency vibration helps the plastic to fully fill the mold cavity, reducing the generation of bubbles and voids. By adding an elastic gasket 51 between the upper mold 21 and the lower mold 22 of the sub-mold unit 2 to absorb the impact force when the mold is closed, the service life of the mold is extended. At the same time, a layer of Teflon coating 232 is coated on the mold surface to improve the anti-sticking performance and facilitate demolding.
