Description

Technical Field

[0001] The invention relates to the technical field of plastic blow molding equipment, in particular to a plastic blow molding equipment. Background Art

[0002] Extrusion blow molding is a method for manufacturing hollow thermoplastic parts. Well-known blow molding objects include bottles, barrels, cans, boxes and all containers for packaging food, beverages, cosmetics, medicines and daily necessities. The tubular plastic preform obtained by extrusion or injection molding of thermoplastic resin is placed in a split mold while hot. After the mold is closed, compressed air is immediately introduced into the preform to inflate the plastic preform and make it close to the inner wall of the mold. After cooling and demolding, various hollow products are obtained.

[0003] The existing blow molding device needs to use different blow molding molds when blow molding plastic products with different structures. The molds are generally fixed on the blow molding equipment by bolts and other connectors, which makes it difficult to replace molds with different structures. At the same time, one side of the mold is installed on a movable push plate, which is guided and moved by the rail shaft. Due to the presence of lubricating medium on the surface of the rail shaft and long-term exposure to the air, the viscosity of the lubricating medium easily absorbs various dust particles. The dust accumulates and adheres to the surface of the rail shaft to form resistance, affecting the normal movement of the movable push plate. Therefore, a plastic blow molding device is needed to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A plastic blow molding device comprises a blow molding processing table, a control module is arranged on the top of the blow molding processing table, and a plate group is arranged on the left side of the control module, the plate group comprises a frame plate, guide components are installed at the four corners of the inner wall of the frame plate, and the right side of the guide component is connected to the control module, a die assembly is movably installed on the outer side of the guide component, the die assembly comprises a pressing plate, a cylinder is connected to the left side of the pressing plate, and the cylinder end is connected and fixed to the inner wall of the frame plate, an installation groove is opened on the right side of the pressing plate, and a closing mold plate is embedded in the installation groove, and the two sides of the closing mold plate are locked and fixed by fixing components. When the closing mold plate is installed, the closing mold plate can be positioned by the installation groove of the pressing plate to ensure the convenience of installing the closing mold plate and keep the center of the closing mold plate and the control module on the same horizontal line.

[0006] Preferably, the guiding component comprises a rail shaft, and the rail shaft passes through the side of the pressure plate through a through groove. A spring scraper is sleeved on the outer side of the rail shaft, and both sides of the spring scraper are connected and fixed to the pressure plate and the inner wall of the frame plate. Through the design of the rail shaft, the pressure plate can be suspended to ensure the convenience of moving the pressure plate. The spring scraper is docked with the pressure plate through the right side. When the pressure plate moves on the surface of the rail shaft, the spring scraper can be controlled to retract and retract. The deformation generated when the spring scraper retracts and retracts can scrape and clean the dust blocks on the surface of the rail shaft.

[0007] Preferably, the fixing component includes a rotating shaft, a rotating disk is connected to the left side of the rotating shaft, and the rotating disk is installed inside the pressure plate through a rotating groove, an anti-dropping block is connected to the side of the rotating shaft, and the anti-dropping block is embedded in the side of the closing template through the groove, and a dial plate is connected to the side of the rotating shaft close to the anti-dropping block, and a rubber end is sleeved on the outer side of the rotating disk to increase the friction force when the rotating disk rotates, thereby preventing the anti-dropping block from easily moving after adjustment, and the dial plate is used to control the clamping state between the anti-dropping block and the closing template slot.

[0008] Preferably, two buckling components are symmetrically installed at the upper and lower ends of the right side of the pressure plate, and the buckling components include a movable shaft, which is inserted into the inside of the pressure plate through a through hole, and a reset spring is connected between the movable shaft and the through hole of the pressure plate, and a positioning buckle plate is connected to the bottom end of the right side of the movable shaft, and the positioning buckle plate is clamped on the surface of the closing template through a groove, and the movable shaft can be driven to move by the rebound force of the reset spring, so that the movable shaft can drive the positioning buckle plate to buckle in the groove on the side of the closing template during movement, and then the closing template can be positioned.

[0009] Preferably, the left and right movable shafts are connected and fixed by a connecting rod, and two limit blocks are symmetrically connected to both sides of the movable shaft, and the limit blocks are embedded in the inner wall of the through hole of the pressure plate through a limit groove. The limit block is embedded in the limit groove in the through hole of the pressure plate, which can prevent the limit block from escaping from the through hole of the pressure plate during movement.

[0010] Preferably, the pressure plate is provided with perfusion holes at the top and sides, a second locking screw cap is threadedly inserted into the perfusion hole at the top of the pressure plate, a first locking screw cap is inserted into the perfusion holes on both sides of the pressure plate, a pipe groove is provided in the perfusion hole of the pressure plate, and the ends of the pipe groove are connected with the through groove of the pressure plate, and by rotating and removing the first locking screw cap and the second locking screw cap, it is convenient for the staff to perfuse the lubricating medium into the pipe groove of the pressure plate, so that the lubricating medium can drip onto the surface of the rail shaft through the pipe groove.

The coating cotton tube is inserted in the through groove of the pressure plate, and the coating cotton tube is attached to the surface of the rail shaft. When the pressure plate moves, it can drive the coating cotton tube to move on the surface of the rail shaft. The coating cotton tube can evenly coat the lubricating medium on the surface of the rail shaft to ensure the smoothness of the movement of the pressure plate.

[0012] Preferably, fixed blocks are installed on both sides of the right side of the smear cotton tube, and the fixed blocks are inserted into the surface of the pressure plate through the slots, and protrusions are provided on both sides of the fixed blocks.

[0013] Preferably, a hanging rail is installed on the side of the frame plate through a guide groove, and the bottom end of the hanging rail is connected to a side transparent door panel. A handle is connected to the front of the side transparent door panel. The hanging rail can be guided by the guide groove of the frame plate to enable the side transparent door panel to move during suspension, thereby preventing the traditional side transparent door panel from falling to the ground and sliding, causing accumulation of debris in the rail groove.

[0014] The present invention has at least the following beneficial effects: 1. By setting up buckling parts and fixing parts, quick replacement of the mating templates can be achieved. Compared with the traditional structure, the device can drive the dial plate to rotate the rotating shaft by toggling the dial plate, and the rotating shaft can drive the anti-detachment block to rotate, and then control the anti-detachment block to disengage from the locking groove on the side of the mating template. At this time, the connecting rod can be pulled outward, and the movable shafts on both sides can be controlled to move in the through holes in the pressure plate, so that the positioning buckle plate is separated from the groove of the mating template.

[0015] 2. By setting up the guiding components, the scraping and cleaning of the attachments on the rail shaft surface can be achieved. The device pushes and displaces the pressure plate through the cylinder, and the pressure plate moves on the rail shaft surface, and then the spring scraper can be repeatedly compressed and extended. The spring scraper scrapes and cleans the rail shaft surface during repeated deformation, which is convenient for cleaning the dust blocks attached to the rail shaft surface, reducing the movement resistance of the pressure plate on the rail shaft surface, and ensuring the smooth movement of the pressure plate on the rail shaft surface.

[0016] 3. By setting up a smearing component, a first locking nut cover and a second locking nut cover, the cleaning and lubrication operations on the rail shaft surface are realized. The device inserts the smearing cotton tube into the sliding hole of the pressure plate, so that the fixed block is buckled on the side of the pressure plate slot, and the lubricating medium is put in from the through holes on the side and top of the pressure plate, so that the lubricating medium is soaked along the pipe groove smearing cotton tube. When the pressure plate moves, it can drive the smearing cotton tube to lubricate the rail shaft surface, thereby further improving the smoothness of the movement of the pressure plate.

[0021] Reference Figure 1-8 A plastic blow molding device includes a blow molding table 1, a control module 2 is arranged on the top of the blow molding table 1, and a plate group 3 is arranged on the left side of the control module 2, the plate group 3 includes a frame plate 31, guide components 35 are installed at the four corners of the inner wall of the frame plate 31, and the right side of the guide component 35 is connected to the control module 2, and a die assembly 4 is movably installed on the outer side of the guide component 35, and the die assembly 4 includes a pressing plate 41, a cylinder 42 is connected to the left side of the pressing plate 41, and the cylinder end of the cylinder 42 is connected and fixed to the inner wall of the frame plate 31, an installation groove is opened on the right side of the pressing plate 41, and a closing plate 43 is embedded in the installation groove, and the closing plate 43 is locked and fixed on both sides by fixing components 46.

A spring scraper 352 is sleeved on the outer side of the rail shaft 351 , and both sides of the spring scraper 352 are connected and fixed to the pressure plate 41 and the inner wall of the frame plate 31 .

[0023] The fixing component 46 includes a rotating shaft 462, a rotating disk 461 is connected to the left side of the rotating shaft 462, and the rotating disk 461 is installed inside the pressure plate 41 through a rotating groove, an anti-slip block 464 is connected to the side of the rotating shaft 462, and the anti-slip block 464 is embedded in the side of the closing template 43 through the groove, and a shift plate 463 is connected to the side of the rotating shaft 462 near the anti-slip block 464.

[0024] Two buckling parts 45 are symmetrically installed at the upper and lower ends of the right side of the pressure plate 41. The buckling parts 45 include a movable shaft 451. The movable shaft 451 is inserted into the inside of the pressure plate 41 through a through hole. A return spring 453 is connected between the movable shaft 451 and the through hole of the pressure plate 41. A positioning buckle plate 455 is connected to the bottom end of the right side of the movable shaft 451, and the positioning buckle plate 455 is clamped on the surface of the closing template 43 through a groove.

[0025] The left and right movable shafts 451 are connected and fixed by a connecting rod 454 . Two limit blocks 452 are symmetrically connected to both sides of the movable shaft 451 . The limit blocks 452 are embedded in the inner wall of the through hole of the pressing plate 41 through limit grooves.

[0026] The top and sides of the pressing plate 41 are provided with injection holes, a second locking screw cover 48 is threadedly inserted into the injection hole at the top of the pressing plate 41, and first locking screw covers 47 are inserted into the injection holes on both sides of the pressing plate 41. A pipe groove is provided in the injection hole of the pressing plate 41, and the ends of the pipe groove are connected to the through groove of the pressing plate 41.

[0027] A coating component 44 is inserted into the through groove of the pressing plate 41 . The coating component 44 includes a coating sponge 441 . The coating sponge 441 is inserted into the through groove of the pressing plate 41 . The coating sponge 441 is attached to the surface of the rail shaft 351 .

[0028] Fixed blocks 442 are installed on both sides of the right side of the smear cotton tube 441, and the fixed blocks 442 are inserted into the surface of the pressing plate 41 through the card slots.

[0029] A hanging rail 33 is suspended and installed on the side of the frame plate 31 through a guide groove, and the bottom end of the hanging rail 33 is connected to a side transparent door plate 32, and the front side of the side transparent door plate 32 is connected to a handle 34.

[0030] When installing the mating template 43, the mating template 43 can be positioned through the installation groove of the pressure plate 41 to ensure the convenience of installation of the mating template 43, so that the center of the mating template 43 and the control module 2 are maintained on the same horizontal line, and the pressure plate 41 can be guided by the guide component 35, and the piston end of the cylinder 42 can push the pressure plate 41 to move stably and avoid the displacement of the pressure plate 41 during movement. Through the design of the rail shaft 351, the pressure plate 41 can be suspended to ensure the convenience of movement of the pressure plate 41.

[0031] At the same time, the right side of the spring scraper 352 is connected to the pressure plate 41, and the pressure plate 41 can control the spring scraper 352 to extend and retract when the surface of the rail shaft 351 moves. The deformation of the spring scraper 352 when it extends and retracts can scrape and clean the dust blocks on the surface of the rail shaft 351, thereby ensuring the cleanliness of the surface of the rail shaft 351 and reducing the resistance of the pressure plate 41 when it moves. A rubber end is sleeved on the outer side of the turntable 461 to increase the friction force when the turntable 461 rotates, thereby preventing the anti-detachment block 464 from easily moving after the adjustment is completed. The design of the dial plate 463 on the side of the rotating shaft 462 can facilitate the staff to operate the dial plate 463, and then control the clamping state between the anti-detachment block 464 and the card slot of the closing template 43, thereby ensuring the stability of the closing template 43 after installation.

[0032] When the plate 43 is initially installed, the return force of the reset spring 453 can drive the movable shaft 451 to move, so that the movable shaft 451 can drive the positioning buckle plate 455 to buckle in the groove on the side of the plate 43 during movement, and then the plate 43 can be positioned to prevent the plate 43 from falling during installation. The limit block 452 is embedded in the limit groove in the through hole of the pressure plate 41 to prevent the limit block 452 from escaping from the through hole of the pressure plate 41 during movement. The elastic design of the reset spring 453 can quickly pull the movable shaft 451 back to its original position, change the limit state of the control positioning buckle plate 455 and the plate 43, and when the pressure plate 4 When the surface of the rail shaft 351 is displaced, the first locking screw cap 47 and the second locking screw cap 48 can be rotated and removed, so that the staff can pour the lubricating medium into the pipe groove of the pressing plate 41, so that the lubricating medium can drip onto the surface of the rail shaft 351 through the pipe groove, thereby ensuring the smooth movement of the pressing plate 41. The smearing cotton cylinder 441 is embedded in the through groove of the pressing plate 41. When the lubricating medium drips through the pipe groove, the smearing cotton cylinder 441 can be soaked. When the pressing plate 41 moves, the smearing cotton cylinder 441 can be driven to move on the surface of the rail shaft 351. The smearing cotton cylinder 441 can evenly smear the lubricating medium onto the surface of the rail shaft 351, thereby ensuring the smooth movement of the pressing plate 41.

[0033] When the smear cotton tube 441 is inserted into the through groove of the pressure plate 41, the fixed block 442 can be inserted into the groove of the pressure plate 41. Protrusions are set on both sides of the fixed block 442. The convex surface of the fixed block 442 is inserted into the corresponding concave surface of the inner wall of the groove of the pressure plate 41, which can ensure the convenience and stability of the installation of the smear cotton tube 441. The guide groove of the frame plate 31 can guide the hanging rail 33 so that the side transparent door panel 32 can move during the suspension, preventing the traditional side transparent door panel 32 from falling and sliding, causing debris to accumulate in the rail groove, and reducing the side transparent door panel. In order to reduce the probability of jamming of the frame plate 31 during movement, the side transparent door panel 32 is moved and then the side of the frame plate 31 is docked, which can reduce the probability of dust adhering to the surface of the rail shaft 351. The control module 2 has a built-in water cooling circulation module, a sample mold, and an external control panel. This structural combination belongs to the existing publicly known technology and will not be explained in detail here. The external control panel design of the control module 2 can conveniently control the start and stop of the water cooling circulation module and the closing operation of the sample mold. The design of the connecting rod 454 between the two movable shafts 451 can facilitate the synchronous movement of the two horizontal movable shafts 451.

[0034] By moving the dial plate 463, the dial plate 463 can drive the rotating shaft 462 to rotate, and the rotating shaft 462 can drive the anti-detachment block 464 to rotate, thereby controlling the anti-detachment block 464 to disengage from the locking groove on the side of the closing template 43. At this time, the connecting rod 454 can be pulled outward, and the movable shafts 451 on both sides can be controlled to move in the through holes in the pressure plate 41, so that the positioning buckle plate 455 is separated from the groove of the closing template 43. At this time, the closing template 43 can be pulled outward and pushed out from the rear side, ensuring the convenience of disassembly and assembly of the closing template 43.

[0035] Working principle: According to the attached Figure 1 With attached Figure 2 As shown, during use, the handle 34 can be held and pulled, and the handle 34 can be forced to drive the side transparent door plate 32 to move, and the side transparent door plate 32 can drive the hanging rail 33 to move in the slide groove of the inner wall of the frame plate 31. At this time, the frame plate 31 is unfolded, and the first locking screw cover 47 and the second locking screw cover 48 are twisted and removed, and the lubricating medium is added from the injection hole of the pressing plate 41, so that the lubricating medium flows through the pipe groove of the pressing plate 41, so that the lubricating medium soaks the smearing cotton tube 441, and when the piston end of the cylinder 42 is extended and retracted, the pressing plate 41 can drive the smearing cotton tube 441 to move on the surface of the rail shaft 351, and then the surface of the rail shaft 351 is evenly smeared, and the spring scraper 352 can be controlled to stretch and deform on the surface of the rail shaft 351 during the movement of the pressing plate 41, and the movement of the spring scraper 352 can scrape and clean the surface of the rail shaft 351, thereby reducing the probability of dust particles adhering to the surface of the spring scraper 352 to form blocks; Secondly, according to the attached Figure 4 , Attachment Figure 6 With attached Figure 7 As shown, the dial plate 463 can be moved, and the force on the dial plate 463 can drive the rotating shaft 462 to rotate, and the rotating shaft 462 can drive the anti-detachment block 464 to disengage from the slot on the side of the closing template 43. At this time, the connecting rod 454 is pulled outward, and the connecting rod 454 drives the movable shaft 451 to move during the movement, and then the reset spring 453 is stretched. At this time, the positioning buckle plate 455 can be separated from the groove on the surface of the closing template 43, so that the closing template 43 can be separated from the rear side of the placement slot of the pressure plate 41 and pulled out, and then the closing template 43 can be replaced conveniently.
