Abstract
Description
Technical Field
[0001] This utility model relates to the field of porous extrusion hose mold processing technology, specifically to a drilling device for porous extrusion hose mold processing. Background Technology
[0002] A porous extrusion hose mold is a special extrusion molding die used to produce porous hoses. It is a type of molding die that processes raw materials into hoses with a porous structure through an extrusion process. It is widely used in the fields of plastics, aluminum and other materials. It is a sub-type of molding die. Drilling is required when processing a porous extrusion hose mold.
[0003] In the prior art, a Chinese patent document with publication number CN209681220U was proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a drilling device for high-precision mold processing, including a base, an electric push rod fixedly connected to the upper surface of the base, a movable plate fixedly connected to the telescopic end of the electric push rod, a rotary motor fixedly connected to the bottom surface of the movable plate, and a drill rod fixedly connected to the output end of the rotary motor.
[0004] To address the dust collection issue during mold drilling, existing technology employs a setup of inclined blocks, cavity A, cavity B, a filter, a fan, and a dust extraction hole. Dust and debris generated during drilling are either restricted by limiting grooves. The fan then generates suction, causing airflow that carries dust and debris through the through-hole into cavity A for processing. However, the suction hole is located below the placement plate, and the suction is covered by the plate, resulting in incomplete dust collection. In particular, dust and debris generated above the placement plate cannot be effectively sucked into the through-hole, leaving a significant amount of dust and debris remaining in the working area, failing to achieve the desired cleanliness. Utility Model Content
[0005] The purpose of this invention is to provide a drilling device for processing multi-hole extrusion hose molds, so as to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A drilling device for processing multi-hole extrusion hose molds includes a drilling device, which includes a support bracket.

[0027] 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.
[0028] Example 1
[0029] like Figure 1-5 As shown, this utility model provides a drilling device for processing multi-hole extrusion hose molds, including a drilling device 1. The drilling device 1 includes a support bracket 2. A bearing plate 3 is fixedly installed on the bottom right side of the support bracket 2. A dust collection box 4 is fixedly installed on the top of the bearing plate 3. A hydraulic cylinder 21 is fixedly installed on the top of the support bracket 2. A piston rod 22 is fixedly installed on the output end of the hydraulic cylinder 21. A dust collection unit is provided at the bottom of the support bracket 2. A processing unit is provided on the right side of the support bracket 2. The dust collection unit includes a piston rod 22 fixedly installed at the bottom of the support bracket 2. 2. A connecting cylinder 23 is attached to the other end. A connecting ring plate 24 is fixedly sleeved on the outer surface of the connecting cylinder 23. A sliding rod 25 is movably inserted around the connecting ring plate 24. A dust collection cover 26 is fixedly connected to the other end of the sliding rod 25. The dust collection cover 26 is slidably sleeved on the outer surface of the connecting cylinder 23. A return spring 27 is sleeved on the outer surface of the sliding rod 25 between the connecting ring plate 24 and the dust collection cover 26. A ring suction cover 28 is fixedly installed around the dust collection cover 26. A suction nozzle 29 is fixedly installed on the inner side of the ring suction cover 28. A drill bit 210 is provided at the bottom end of the connecting cylinder 23.
[0030] Furthermore, the piston rod 22 is driven downward by the hydraulic cylinder 21, which causes the connecting cylinder 23 and the drill bit 210 at the bottom to descend vertically and drill holes in the multi-hole extrusion tube mold. When drilling, the dust collection hood 26 first contacts the mold surface and stops moving downward due to the mold's obstruction. Meanwhile, the connecting cylinder 23 continues to descend and compresses the return spring 27, so that the dust collection hood 26 fits tightly against the mold surface, forming a closed dust collection space to prevent dust generated during drilling from overflowing.
[0031] Example 2
[0032] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the processing unit includes a dust pump 41 fixedly installed on the right side of the support bracket 2 at the top right side of the dust collection box 4. The connecting end of the dust pump 41 extends into the inside of the right side of the dust collection box 4 and is fixedly installed with a dustproof net. A suction pipe 211 is fixedly installed on the right side of the ring suction cover 28. The other end of the suction pipe 211 is fixedly installed inside the top left side of the dust collection box 4. A corrugated pipe 212 is provided in the middle position of the suction pipe 211.
[0033] Furthermore, by starting the vacuum pump 41, a negative pressure suction is generated in conjunction with the vacuum pipe 211 and the corrugated pipe 212. Then, the vacuum nozzle 29 on the inner side of the ring suction hood 28 is brought close to the drilling area to suck the dust and debris generated during drilling into the ring suction hood 28. The dust and debris are then transported to the interior of the dust collection box 4 through the vacuum pipe 211, so that drilling and vacuuming can be carried out simultaneously.
[0034] Example 3
[0035] like Figure 1-5 As shown, based on embodiments 1-2, this utility model provides a technical solution: Preferably, a gathering cover 42 is fixedly installed at the top of the dust collection box 4, a circulation pump 43 is fixedly installed at the bottom rear side of the dust collection box 4, a liquid extraction pipe 44 is fixedly installed at the input end of the circulation pump 43, the other end of the liquid extraction pipe 44 is fixedly installed inside the rear side of the dust collection box 4, a drain pipe 45 is fixedly installed at the output end of the circulation pump 43, the other end of the drain pipe 45 extends inside the top of the dust collection box 4 and is fixedly connected to a spray plate 46, the spray plate 46 is fixedly installed on the top of the gathering cover 42, a filter frame 47 is movably inserted into the middle position of the front side of the dust collection box 4, and a filter frame 48 is movably inserted into the top of the filter frame 47.
[0036] Furthermore, after the dust-laden airflow enters the dust collection box 4 through the suction pipe 211, larger dust particles initially settle to the bottom of the dust collection box under the action of gravity, while smaller dust particles rise with the airflow. At this time, the circulation pump 43 is started in conjunction with the liquid extraction pipe 44 to extract the liquid at the bottom of the dust collection box 4, and it is transported to the spray plate 46 through the drain pipe 45. The spray plate 46 sprays liquid onto the top of the gathering hood 42 to form a water mist. The water mist comes into contact with the rising dust-laden airflow, achieving dust settling. The settled liquid and dust mixture falls back to the bottom of the dust collection box 4, and is further filtered by multiple layers of filter frames 47 and 48 to trap dust, thereby realizing liquid recycling and improving dust reduction.
[0037] The solution uses a PLC as the core control component. The PLC establishes a connection with the hydraulic cylinder 21, the dust pump 41, and the circulation pump 43 via RS-485 communication. When it is necessary to start the hydraulic cylinder 21, the dust pump 41, and the circulation pump 43, the PLC sends a start command to the hydraulic cylinder 21, the dust pump 41, and the circulation pump 43, causing them to start.
[0038] The working principle of the drilling device for processing porous extrusion hose molds will be explained in detail below.
[0039] like Figure 1-5As shown, the piston rod 22 is driven downward by the hydraulic cylinder 21, which in turn drives the connecting cylinder 23 and the drill bit 210 at the bottom to descend vertically and drill holes in the multi-hole extrusion tube mold. During drilling, the dust collection hood 26 first contacts the mold surface and stops descending due to the mold's obstruction. Meanwhile, the connecting cylinder 23 continues to descend, compressing the return spring 27, causing the dust collection hood 26 to fit tightly against the mold surface, forming a closed dust collection space to prevent dust generated during drilling from overflowing. Then, the dust pump 41 is activated, working in conjunction with the suction pipe 211 and the corrugated pipe 212 to generate negative pressure suction. The suction nozzle 29 inside the ring suction hood 28 is then placed close to the drilling area to suck the dust and debris generated during drilling into the ring suction hood 28, and then transported to the dust collection box via the suction pipe 211. Inside the dust collection box 4, drilling and dust collection are carried out simultaneously to prevent dust from spreading outward. After the dust-laden airflow enters the dust collection box 4 through the suction pipe 211, larger dust particles initially settle to the bottom of the dust collection box under the action of gravity, while smaller dust particles rise with the airflow. At this time, the circulation pump 43 is started and the liquid extraction pipe 44 is used to extract the liquid at the bottom of the dust collection box 4. The liquid is then transported to the spray plate 46 through the drain pipe 45. The spray plate 46 sprays liquid onto the top of the gathering hood 42 to form a water mist. The water mist comes into contact with the rising dust-laden airflow, achieving dust settling. The settled liquid and dust mixture fall back to the bottom of the dust collection box 4. After being filtered through multiple layers of filter frames 47 and 48, the dust is further trapped, thereby realizing liquid recycling and improving dust reduction.
[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
