Description

Technical Field

[0002] Prefabricated parts refer to building components that are prefabricated in factories or on-site and can be directly transported to the construction site for installation. There are many types of prefabricated parts, and the more widely used prefabricated parts are prefabricated concrete parts and prefabricated steel components. Among them, common prefabricated concrete components include plates, columns, beams and wall panels, which are made by pouring concrete in molds in factories and then curing them. Common prefabricated steel components include steel columns, steel beams and steel frames, which are processed and manufactured using steel in factories and have the characteristics of high strength and light weight.

[0003] The manufacturing method commonly used in existing precast concrete parts is to use a skeleton made of steel bars, place the skeleton in a mold, pour the prepared concrete into the mold cavity, and demold the concrete after it solidifies, finally forming a precast concrete part. However, the existing precast concrete component forming device still has shortcomings when used. For example, before pouring the precast concrete part, it is usually necessary to spray a mold release agent on the surface of the mold cavity. The existing oil sprayer sprays oil in a fixed position of the mold by manually holding a nozzle or by a fixed nozzle. The oil spraying efficiency is low and the spraying range is small, which is not conducive to quickly completing the oil spraying operation, affecting the preliminary preparations for the production of precast concrete parts, resulting in a long preparation time before pouring, which in turn affects the production efficiency of precast concrete parts, is not conducive to the efficient production of precast parts, and further affects the production efficiency.

[0015] In the above technical solution, the technical effects and advantages provided by the present invention are: (1) An injection mechanism is arranged in the mold shell of the mold assembly. The injection mechanism mainly sprays the release agent into the mold cavity of the mold shell of the mold assembly. In the process of spraying the release agent into the mold cavity, it is only necessary to insert the injection mechanism into the mold shell and then withdraw it to complete the release agent injection work. In this process, the high-pressure gas ejected from the injection pipe impacts the inner wall of the mold shell to complete the cleaning of the inner wall of the mold shell. At the same time, the exhaust pipe on one side of the injection pipe extracts the gas in the mold shell to timely extract the dust-containing impurities. The outer nozzle sprays the release agent on the inner wall of the mold shell and the inner nozzle sprays the release agent on the outer wall of the mold tube. The process is automated and fast, which effectively shortens the preparation time before the casting of prefabricated parts. In factories that produce prefabricated parts in batches, the use of the injection mechanism is conducive to optimizing the casting of prefabricated parts and improving the overall production efficiency.

[0016] (2) By arranging a pretreatment device at the end of the injection mechanism, before the injection mechanism is inserted into the mold shell, the pretreatment device is first inserted into the mold shell, and the outer wall of the mold tube that has been in the mold shell is cleaned, and the injection pipe and the exhaust pipe are used to complete the cleaning task of all structures in the mold shell. Keeping the mold cavity in the mold shell and the outer wall of the mold tube clean is conducive to the adhesion of the release agent, thereby facilitating the role of the release agent, improving the demolding success rate, reducing the defective products caused by demolding failure, and effectively improving the economic benefits.

[0017] (3) By setting a rotating ring in the pretreatment device, the pretreatment device passes through the mold tube again during the process of pulling out the injection mechanism. At this time, high-pressure gas is injected into the secondary air intake ring through the conduit. The secondary air intake ring guides the gas into the main air intake channel of the second pipeline. The high-pressure gas is ejected from the port of the main air intake channel and blown to the groove on the side of the rotating ring. The rotating ring rotates due to the continuous high-pressure gas blowing. During the rotation, the release agent is evenly applied to the outer wall of the mold tube, which is beneficial to improve the uniformity of the release agent on the outer wall of the mold tube, which is beneficial to further ensure smooth demolding and optimize processing performance.

When the rotating ring 7322 moves, the scraper ring 7331 scrapes the dust on the outer surface of the mold tube 3 without directly scratching the outer wall of the mold tube 3. The pretreatment device 73 also includes a second pipe 732 connected to the end of the third pipe 733, the end of the second pipe 732 is connected to the first pipe 731, the outer wall of the second pipe 732 is provided with a main air inlet channel 7321, the extension end of the main air inlet channel 7321 extends to the inner wall of the second pipe 732, the inner wall of the second pipe 732 is provided with a placement groove 7323 on one side close to the extension end of the main air inlet channel 7321, a rotating ring 7322 is provided on one side of the placement groove 7323, the inner wall of the rotating ring 7322 is provided with a coated rubber ring 7326, and one side of the rotating ring 7322 is provided with a plurality of The air collecting groove 7325 is provided with a slip ring 7324 on the other side. A sliding groove 7311 matching with the slip ring 7324 is provided on the side of the first pipe 731 close to the second pipe 732. A secondary air intake ring 735 is sleeved on the outer wall of the second pipe 732. The interior of the secondary air intake ring 735 is a hollow structure, and a hole corresponding to the main air intake channel 7321 is provided on the inner wall of the secondary air intake ring 735. Two hoses 7351 are symmetrically provided on the outer wall of the secondary air intake ring 735. The lengths of the hoses 7351 and the connecting pipe 7341 are mainly selected according to the lengths required in the specific installation process to ensure smooth installation. A conduit 751 is further provided at one side of the end of the air inlet pipe 75 close to the air jet pipe 72.

The air collecting groove 73 25 is arranged at an angle on the rotating ring 7322, and the gas pushes the rotating ring 7322 to rotate in the placement groove 7323, and the rotating ring 7322 rotates more smoothly and stably under the cooperation of the slip ring 7324 and the slide groove 7311. The rotating ring 7322 moves horizontally outside the mold tube 3 while rotating outside the mold tube 3, and the mold release agent on the outer surface of the mold tube 3 is evenly applied, so that the mold release agent on the outer surface of the mold tube 3 will not sag and will not drip downward, which is conducive to improving the success rate of demoulding.

[0025] By closing the solenoid valve 752, the gas only passes through the conduit 751 and is delivered to the primary air intake ring 734 and the secondary air intake ring 735.

At this time, the pretreatment device 73 is just inserted into the mold shell 5 and is sleeved on the outside of the mold tube 3. The gas is mainly ejected from the injection pipe 72 and impacts the inner wall of the mold shell 5.

Use a bolt (not shown in the figure) with a screw rod of sufficient length to pass through the threaded holes 78 of the first pipe 731, the second pipe 732, and the third pipe 733 to connect the three pipe structures in series, and the end of the bolt is threadedly connected with the threaded hole 78 on the end face of the inner nozzle 77. The pretreatment device 73 is fixed as a whole on the end face of the inner nozzle 77, and the holes in the middle of the first pipe 731, the second pipe 732, and the third pipe 733 correspond to the circular holes on the surface of the inner nozzle 77. The diameters of the two holes are the same, so that the mold tube 3 can pass through the above two holes. The end of the air inlet pipe 75 is inserted into the through hole 79 from the front surface of the outer nozzle 76. The air inlet pipe 75 is pushed to pass through the through hole 79, and then the jet pipe 72 and the conduit 751 (such as Figure 8 , Fig. 9 and Fig.10 As shown), similarly, the end of the exhaust pipe 74 is also inserted into the through hole 79 from the front surface of the outer nozzle 76, and the exhaust pipe 71 is plugged into its end.
