Description

Technical Field

[0001] This invention relates to the field of testing instrument manufacturing, specifically to an injection mold for processing the casing of a testing instrument. Background Technology

[0002] The oxygen detector is a smart oxygen detection and alarm instrument that can be easily carried by a single hand. It is mainly used in underground tunnels, pipelines, manhole covers and other places to detect oxygen deficiency and trace amounts of oxygen. By detecting the concentration of oxygen in the environment, the oxygen detector can determine whether there is a risk of oxygen deficiency or explosion, or control the quality of products manufactured by enterprises through the oxygen concentration.

[0003] In the oxygen detector, the outer casing needs to be injection molded. The existing injection molding technology for the oxygen detector casing first installs the mold on a fixture, then moves the moving mold to the stationary mold by a cylinder, and then injects the material between the moving mold and the stationary mold through the injection head. After the injection is completed, the injection molded part is cooled. After cooling, the injection molded part is dropped off the mold by a pushing mechanism, and then the mold is collected. This completes the injection molding of the detector casing.

[0004] In existing technologies, when removing the injection molded part after injection molding, it is necessary to first wait for the injection molded part to cool on the mold. After cooling, the injection molded part needs to be removed from the stationary mold using ejector pins. Then, the loose injection molded part is manually removed from the stationary mold. However, waiting for the injection molded part to cool takes a certain amount of time, which affects work efficiency. Furthermore, after prolonged use, the surface of the mold will be covered with injection molding material, which will have a certain impact on the subsequent simple shaping and thus reduce product quality. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide an injection mold for processing the housing of a testing instrument, so as to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an injection mold for processing the housing of a testing instrument, comprising a base and a working chamber, wherein a first rotating mechanism is provided on the inner side of the working chamber, and the first rotating mechanism includes a first rotating shaft, a motor and a lifting mechanism, the first rotating shaft is located on the inner side of the working chamber, the motor is located at the end of the first rotating shaft, the lifting mechanism is located above the first rotating shaft, the inner wall of the first rotating shaft is provided with a sliding groove, and the sliding groove connects the first rotating shaft and the lifting mechanism, and a moving mold is provided on the inner side of the working chamber.

[0007] By adopting the above technical solution, after injection molding is completed, the motor is rotated through the first rotating shaft, and the sliding groove connection between the first rotating shaft and the lifting mechanism ensures that the lifting mechanism will not rotate when the first rotating shaft rotates, thereby driving the mold to rotate.

[0008] The present invention is further configured such that the lifting mechanism includes a cylinder, a telescopic column, two sets of fixed plates, a limiting rod, a connecting rod, and a sliding ring, wherein the cylinder is disposed above the first rotating shaft, the telescopic column is disposed below the cylinder, the two sets of fixed plates are disposed at the ends of the telescopic column, the limiting rod is disposed in the internal groove of the first rotating shaft, and two sets of connecting rods are disposed at both ends of the limiting rod, and each set of connecting rods has three rods, and the sliding ring is disposed in the inner wall groove of the first rotating shaft.

[0009] By adopting the above technical solution, the cylinder is activated, causing the two sets of fixed discs to move up and down. The first rotating shaft is connected to the fixed discs by a sliding ring through a sliding groove, ensuring that the fixed discs do not rotate when the first rotating shaft rotates, thus creating relative motion.

[0010] The present invention is further configured such that two sets of extrusion mechanisms are symmetrically arranged on the outer side of the first rotating shaft, and the extrusion mechanism includes a threaded sleeve, a gear and a transmission mechanism. The threaded sleeve is arranged on the outer side of the first rotating shaft, the gear is arranged on the outer side of the end of the threaded sleeve, and the transmission mechanism is arranged on the inner side of the threaded sleeve.

[0011] By adopting the above technical solution, when the outer teeth of the fixed disk and the gear are meshed, it is ensured that when the first rotating mechanism drives the threaded sleeve to rotate around the first rotating shaft, the gear completes its rotation, thereby causing the threaded sleeve to rotate. Furthermore, through the threaded connection between the threaded sleeve and the transmission mechanism, the transmission mechanism extends outward along the threaded sleeve.

[0012] The present invention is further configured such that the outer end of the fixed disk is provided with teeth, and the teeth on the outer end of the fixed disk form a meshing connection with the gear.

[0013] By adopting the above technical solution, the meshing connection between the teeth and gears on the outer side of the fixed disk ensures that when the first rotating shaft drives the gear to rotate around the first rotating shaft, the gear will complete its own rotation.

[0014] The present invention is further configured such that the transmission mechanism includes a threaded rod, a first rotating head and a second rotating shaft, wherein the threaded rod is disposed inside the threaded sleeve rod, the first rotating head is disposed at the end of the threaded rod, and the second rotating shaft is disposed inside the first rotating head and passes through the first rotating head.

[0015] By adopting the above technical solution, when the threaded rod extends outward, the limiting of the first rotating head and the second rotating shaft ensures that the threaded rod always moves forward, so that the mold completes the circumferential motion.

[0016] The present invention is further configured such that a second rotating mechanism is provided below the extrusion mechanism, and the second rotating mechanism includes a fixed column, a second rotating head and a third rotating shaft. The fixed column is located outside the first rotating shaft, the second rotating head is located at the end of the fixed column, and the third rotating shaft is located inside the second rotating head and passes through the second rotating head.

[0017] By adopting the above technical solution, when the mold is pushed by the extrusion mechanism, the mold rotates around the third rotating shaft. At this time, the rotating installation structure is completed in the groove at the bottom of the mold by the second rotating head, thereby ensuring that the mold completes the rotation and makes the mold tilt.

[0018] The present invention is further configured such that the interior of the moving mold is hollow, and a water inlet is provided on the outer side of the moving mold. Two sets of sliding grooves are provided on the side of the moving mold near the first rotating mechanism. The inner wall of the first set of sliding grooves on the side of the moving mold near the first rotating mechanism is provided with a groove. The groove on the inner wall of the first set of sliding grooves on the outer side of the moving mold and the second rotating shaft are slidably mounted. The other set of grooves on the side of the moving mold near the first rotating mechanism extends to the bottom of the moving mold. The second rotating head and the groove at the bottom of the moving mold form a rotating mounting structure.

[0019] By adopting the above technical solution, the sliding groove provided on the side of the moving mold near the first rotating mechanism ensures that the extrusion mechanism always supports the moving mold when the moving mold rotates with the center of the third rotating shaft, thereby ensuring that the moving mold completes the tilting state.

[0020] The present invention is further configured such that a cooling mechanism is provided on the outer side of the moving mold, and the cooling mechanism includes a support plate, an air bladder, an extrusion plate, a first water inlet pipe and a limiting block. The support plate is disposed between the moving mold and the first rotating mechanism, and the height of the support plate is lower than that of the extrusion mechanism. The air bladder is disposed on the inner side of the support plate, and the extrusion plate is disposed between the inner wall of the support plate and the outer wall of the air bladder. The first water inlet pipe is disposed on the outer side of the support plate and extends to the inner side of the moving mold. The limiting block is disposed at the end of the first water inlet pipe, and the width of the limiting block is greater than the width of the groove on the inner side of the moving mold.

[0021] By adopting the above technical solution, when the moving mold rotates around the third rotating shaft, the first water inlet pipe is pulled, causing the extrusion plate to pull the airbag. The water inside the airbag flows to the inside of the moving mold due to atmospheric pressure, thereby ensuring the cooling of the injection molded parts on the outside of the moving mold.

[0022] The present invention is further configured such that the cooling mechanism includes a water outlet pipe, a one-way valve and a water spray nozzle, wherein the water outlet pipe is located above the airbag, the one-way valve is located at the bottom of the water outlet pipe and the water spray nozzle is located at the end of the water outlet pipe.

[0023] By adopting the above technical solution, the water inside the airbag 702 is ensured to move only towards the water outlet pipe through the water outlet pipe and sprayed onto the surface of the moving mold through the water spray nozzle, thereby cleaning the surface of the moving mold.

[0024] In summary, the present invention has the following main beneficial effects: This invention comprises a first rotating mechanism, an extrusion mechanism, and a moving mold. When the motor starts, the first rotating shaft rotates. A groove connection between the first rotating shaft and the lifting mechanism ensures that the fixed plate remains stationary while the first rotating shaft rotates. At this time, the teeth on the outer side of the fixed plate mesh with the gear, causing the gear to drive the threaded sleeve to rotate. The transmission mechanism is threadedly connected to the threaded sleeve, and the end of the threaded sleeve is limited, causing it to extend outwards. This causes the moving mold to rotate around its bottom, completing an arc motion. This causes the injection molded part on the outer side of the moving mold to tilt. The downward component of the injection molded part's own weight causes it to fall. As the first rotating shaft continues to rotate, the two sets of injection molded parts work alternately, reducing the time spent waiting to clean the injection molded parts and improving work efficiency.

[0025] This invention incorporates a moving mold and a cooling mechanism. When the moving mold moves in an arc around its bottom, the pressure inside the airbag changes by pulling the limiting block, causing water inside the airbag to flow into the moving mold. This water cools the injection molded part, reducing the waiting time for the part to cool down. Furthermore, the water outlet pipe, one-way valve, and spray nozzle allow water from inside the airbag to be sprayed onto the outer surface of the moving mold, thus cleaning the surface of the moving mold. This reduces the time required for manual cleaning of the moving mold surface and improves production efficiency. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of the present invention will now be described.

[0030] An injection mold for processing the housing of a testing instrument, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a base 1 and a working chamber 2. A first rotating mechanism 3 is provided inside the working chamber 2. The first rotating mechanism 3 includes a first rotating shaft 301, a motor 302, and a lifting mechanism 303. The first rotating shaft 301 is located inside the working chamber 2, and the motor 302 is located at the end of the first rotating shaft 301. The lifting mechanism 303 is located above the first rotating shaft 301. A sliding groove is provided on the inner wall of the first rotating shaft 301, and the sliding groove connects the first rotating shaft 301 and the lifting mechanism 303. A moving mold 6 is provided inside the working chamber 2. After injection molding is completed, the motor 302 is rotated through the first rotating shaft 301. The sliding groove between the first rotating shaft 301 and the lifting mechanism 303 ensures that the lifting mechanism 303 will not rotate when the first rotating shaft 301 rotates, thereby driving the mold to rotate.

[0031] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The lifting mechanism 303 includes a cylinder 3031, a telescopic column 3032, two sets of fixed plates 3033, a limiting rod 3034, a connecting rod 3035, and a sliding ring 3036. The cylinder 3031 is located above the first rotating shaft 301, the telescopic column 3032 is located below the cylinder 3031, and the two sets of fixed plates 3033 are located at the ends of the telescopic column 3032. The limiting rod 3034 is located in the internal groove of the first rotating shaft 301, and the connecting rod 3035 has... Two sets are set at both ends of the limiting rod 3034, and each set of connecting rods 3035 is provided with three. The sliding ring 3036 is set in the inner wall groove of the first rotating shaft 301. By starting the cylinder 3031, the two sets of fixed disks 3033 move up and down. The sliding ring 3036 completes the groove connection between the first rotating shaft 301 and the fixed disks 3033, ensuring that when the first rotating shaft 301 rotates, the fixed disks 3033 will not rotate, thus forming relative motion.

[0032] Please see Figure 2 and Figure 6 Two sets of extrusion mechanisms 4 are symmetrically arranged on the outer side of the first rotating shaft 301. Each extrusion mechanism 4 includes a threaded sleeve 401, a gear 402, and a transmission mechanism 403. The threaded sleeve 401 is located on the outer side of the first rotating shaft 301, and the gear 402 is located on the outer side of the end of the threaded sleeve 401. The transmission mechanism 403 is located on the inner side of the threaded sleeve 401. When the outer teeth of the fixed disk 3033 mesh with the gear 402, it ensures that when the first rotating mechanism 3 drives the threaded sleeve 401 to rotate around the first rotating shaft 301, the gear 402 rotates, thereby causing the threaded sleeve 401 to rotate. Through the threaded connection between the threaded sleeve 401 and the transmission mechanism 403, the transmission mechanism 403 extends outward along the threaded sleeve 401.

[0033] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The outer end of the fixed disk 3033 is provided with teeth, and the teeth on the outer end of the fixed disk 3033 are meshed with the gear 402. The meshing connection between the teeth on the outer end of the fixed disk 3033 and the gear 402 ensures that when the first rotating shaft 301 drives the gear 402 to rotate around the first rotating shaft 301, the gear 402 will complete its own rotation.

[0034] Please see Figure 6 and Figure 7The transmission mechanism 403 includes a threaded rod 4031, a first rotating head 4032, and a second rotating shaft 4033. The threaded rod 4031 is located inside the threaded sleeve rod 401, and the first rotating head 4032 is located at the end of the threaded rod 4031. The second rotating shaft 4033 is located inside the first rotating head 4032 and passes through the first rotating head 4032. When the threaded rod 4031 extends outward, the first rotating head 4032 and the second rotating shaft 4033 limit the threaded rod 4031 to always advance forward, so that the mold completes the circumferential motion.

[0035] Please see Figure 6 and Figure 7 Below the extrusion mechanism 4, a second rotating mechanism 5 is provided. The second rotating mechanism 5 includes a fixed column 501, a second rotating head 502, and a third rotating shaft 503. The fixed column 501 is located outside the first rotating shaft 301, and the second rotating head 502 is located at the end of the fixed column 501. The third rotating shaft 503 is located inside the second rotating head 502 and passes through the second rotating head 502. When the mold is pushed by the extrusion mechanism 4, the mold rotates around the third rotating shaft 503. At this time, the rotating installation structure is completed in the groove at the bottom of the mold by the second rotating head 502, thereby ensuring that the mold completes the rotation and makes the mold tilt.

[0036] Please see Figure 6 , Figure 7 and Figure 8 The interior of the moving mold 6 is hollow, and two sets of sliding grooves are provided on the side of the moving mold 6 near the first rotating mechanism 3. The inner wall of the first set of sliding grooves on the side of the moving mold 6 near the first rotating mechanism 3 is provided with a groove, and the groove on the inner wall of the first set of sliding grooves on the outer side of the moving mold 6 and the second rotating shaft 4033 are slidably installed. The other set of grooves on the side of the moving mold 6 near the first rotating mechanism 3 extends to the bottom of the moving mold 6, and the second rotating head 502 and the groove at the bottom of the moving mold 6 form a rotating installation structure. Through the sliding grooves on the side of the moving mold 6 near the first rotating mechanism 3, it is ensured that when the moving mold 6 rotates with the third rotating shaft 503 at the center, the extrusion mechanism 4 always supports the moving mold 6, thereby ensuring that the moving mold 6 completes the tilting state.

[0037] Please see Figure 8A cooling mechanism 7 is provided on the outer side of the moving mold 6. The cooling mechanism 7 includes a support plate 701, an air bladder 702, an extrusion plate 703, a first water inlet pipe 704, and a limiting block 705. The support plate 701 is located between the moving mold 6 and the first rotating mechanism 3, and the height of the support plate 701 is lower than that of the extrusion mechanism 4. The air bladder 702 is located on the inner side of the support plate 701, and the extrusion plate 703 is located between the inner wall of the support plate 701 and the outer wall of the air bladder 702. The first water inlet pipe 704 is located on the outer side of the support plate 701. The first water inlet pipe 704 extends to the inner side of the moving mold 6, and the limiting block 705 is located at the end of the first water inlet pipe 704. The width of the limiting block 705 is greater than the width of the groove on the inner side of the moving mold 6. When the moving mold 6 rotates around the third rotating shaft 503, the first water inlet pipe 704 is pulled, causing the extrusion plate 703 to pull the air bag 702. The water inside the air bag 702 flows to the inner side of the moving mold 6 due to atmospheric pressure, thereby ensuring the purpose of cooling the injection molded part on the outer side of the moving mold 6.

[0038] Please see Figure 8 The cooling mechanism 7 also includes a water outlet pipe 706, a one-way valve 707, and a water spray nozzle 708. The water outlet pipe 706 is located above the airbag 702, the one-way valve 707 is located at the bottom of the water outlet pipe 706, and the water spray nozzle 708 is located at the end of the water outlet pipe 706. Through the arrangement of the water outlet pipe 706 and the one-way valve 707, it is ensured that the water inside the airbag 702 will only move towards the water outlet pipe 706, and the water inside the airbag 702 is sprayed onto the surface of the moving mold 6 through the water spray nozzle 708, thereby cleaning the surface of the moving mold 6.

[0039] The working principle of this invention is as follows: When injection molding is required, the moving mold assembly is first moved towards the stationary mold assembly by a power device (such as a cylinder) until the two molds are in contact and injection begins. After injection is completed, water is injected into the water inlet on the outside of the moving mold 6 through the second water inlet pipe 9, filling the moving mold 6 with cooling water. Then, the moving mold is returned to its original position by the cylinder. The first rotating shaft 301 is rotated by starting the motor 302. At this time, the fixed plate 3033 is connected to the first rotating shaft 301 by a sliding groove through the limiting rod 3034, the connecting rod 3035, and the sliding ring 3036. The fixed connection between the first rotating shaft 301, the second rotating mechanism 5, the moving mold 6, and the extrusion mechanism 4 is also achieved. The fixed connection between the output end of the lifting mechanism 303 and the working chamber 2 ensures that when the first rotating shaft 301 rotates, the fixed plate 3033 remains stationary. At this time, the teeth at the top of the lower fixed plate 3033 mesh with the gear 402, causing the threaded sleeve 401 to rotate. This causes the threaded sleeve 4031 to extend horizontally outward, pushing the second rotating shaft 4033 to rotate around the first rotating head 4032. Simultaneously, the first rotating head 4032 moves up and down along the groove on the outer wall of the moving mold 6, causing the moving mold 6 to rotate counterclockwise around the third rotating shaft 503. When the first rotating shaft 301 rotates 90°, the moving mold 6 rotates 90° around the first rotating shaft 301, and the water outlet pipe 706... The airbag 702 is stretched by atmospheric pressure, causing the internal air pressure to drop. Since the one-way valve 707 is a one-way valve, water inside the moving mold 6 flows into the airbag 702 through the first water inlet pipe 704. At this time, the cooling water inside the moving mold 6 cools the injection molded part on the outside of the moving mold 6. When the first rotating shaft 301 rotates 90°, the moving mold 6 rotates 90°, and through the push of the extrusion mechanism 4, the moving mold 6 tilts counterclockwise, causing the mold to fall off the surface of the moving mold 6 due to its own weight. Afterwards, the first rotating shaft 301 continues to rotate, at which point the cylinder 3031 is activated, causing the fixed plate 3033 to move downwards, causing the teeth at the bottom of the upper fixed plate 3033 to engage with the gear 40. The two parts are engaged, and the fixed plate 3033 below disengages from the gear 402. When the first rotating shaft 301 drives the extrusion mechanism 4 to rotate continuously, the gear 402 rotates in the opposite direction, causing the threaded rod 4031 to retract into the threaded sleeve rod 401, thereby resetting the moving mold 6. During the resetting, the second set of moving molds 6 is in the injection position. At the same time, the first water inlet pipe 704 drives the extrusion plate 703 to push the airbag 702, so that the water inside the airbag 702 flows through the extrusion to the water spray nozzle 708 and sprays it onto the surface of the moving mold 6, thereby cleaning the moving mold 6 and ensuring that the residue of the injection molding material will not affect the next injection molding, thereby improving the product. This completes the injection molding step on the outside of the testing instrument.
