[0002] Two-color injection molding machine is a kind of injection molding equipment specially used for producing plastic products with two different colors or materials. It has two or more injection units, which can inject plastic materials of different colors in the same working cycle, thus realizing the process of two-color injection molding.

[0003] At present, when a two-color injection molding machine is in use, the upper mold inside is in a stationary state, while the lower mold is in an active state. When the working area is in a high temperature and humid environment, the exposed end faces of the two molds are in the above environment for a long time, which will produce a large number of rust spots. In severe cases, the peeling of the rust spots will interfere with the shaping of the molten material in the inner mold cavity.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] An integrated injection molding device for automobile interior decoration parts provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings. Embodiment 1:

[0024] Combination Figure 1-Figure 11 As shown, the present invention provides an integrated injection molding device for automotive interior parts, comprising an injection molding machine 100, a positioning mechanism 200 arranged on the injection molding machine 100, a propulsion mechanism 300 arranged on the positioning mechanism 200, a chip removal mechanism 400 arranged on the propulsion mechanism 300, and two sets of die end grinding mechanisms 500 arranged on the chip removal mechanism 400.

[0025] The position control mechanism 200 includes a top plate 210 and a support plate 240, a hydraulic component 260 disposed in the support plate 240, a suspension 270 installed at the bottom end of the hydraulic sub-rod in the hydraulic component 260, a ring rail 280 installed at the bottom of the suspension 270, a notch is opened in the middle of the top surface of the top plate 210, and the support plate 240 is installed in the notch, a screw sleeve 220 installed on the top plate 210, a progressive screw rod 230 that penetrates into the top plate 210 and is installed in the screw sleeve 220, a sliding sleeve 250 disposed in the middle of the inner side of the support plate 240, and two return compression springs 290 that bear pressure in the sliding sleeve 250 and the support plate 240; The propulsion mechanism 300 includes a lifting assembly 310 disposed on the ring rail 280 and a pressure-bearing assembly 350 disposed in the lifting assembly 310; The chip removal mechanism 400 includes a wind bin 410 disposed on the pressure-bearing assembly 350 and a dust removal end 420 for emptying waste chips; The die end grinding mechanism 500 includes a dust collecting bin 510 installed outside the wind bin 410, a grinding head 540 arranged in the dust collecting bin 510 and attached to the end surface of the die, an oiling assembly 550 for oiling, a cushion 520 installed at the bottom of the dust collecting bin 510, a first bearing 530 installed inside the cushion 520, and a tensioning adjustment assembly 560 arranged on the dust collecting bin 510; The oiling assembly 550 includes an oil storage pipe 551, an oil drain tank 552 installed on the oil storage pipe 551, a tension spring 553 connected to the inside of the oil drain tank 552, and a plug gasket 554 connected to the top of the tension spring 553; The tensioning adjustment assembly 560 includes two limit members 561 installed on both sides of the elliptical hole, a slide plate 562 movably installed in the two limit members 561, a clamp 563 installed in the middle of the slide plate 562, a second bearing 564 installed in the clamp 563, and a limit gasket 565 arranged on the threaded section of the clamp 563, and a nut is arranged on the threaded section of the clamp 563, and the nut is pressed on the top of the limit gasket 565.

[0026] Because the traditional two-color injection molding machine is affected by the humid air and high temperature in the working area during use, the end faces of the upper and lower molds inside the injection molding machine will rust. As the degree of rust on the end faces of the mold increases, the molten material will be disturbed by the rust residue on the end faces of the mold. As the rust residue rises, the workers will have certain safety hazards to their hands in the process of cleaning the rust residue.

[0027] The device is provided with a suspended ring rail 280 in the middle of the upper mold and the lower mold, and the beam rail 311 is provided on the ring rail 280. When the flip motor 320 is running, the beam rail 311 will be turned sideways at a uniform speed along the two molds under the auxiliary pressure of the three sliding sleeves 313. At the same time, the two driving screws 460 installed on the transmission shaft of the running servo motor 440 can simultaneously drive the two linkage shafts 570. At this time, the two linkage shafts 570 can cooperate with the two chains 580 to drive the two grinding heads 540. At this time, the two grinding heads 540 can be suspended on the top of the two molds in a non-pressurized state. When the hydraulic sub-rod in the hydraulic component 260 is slightly extended downward, the two suspended grinding heads 540 will grind the end face of the mold at the moment of rotation until the rust residue is removed. At this time, the two dust suction bins 510 can exhaust air to the outside to extract the raised waste chips, thereby avoiding contamination of the inner cavity of the injection molding machine. After the two oiling components 550 arranged on the two dust suction bins 510 are injected with different oils in sequence according to the use requirements, the two mold end faces can be polished after rust removal until the purpose of coating protection is achieved, thereby reducing the difficulty of operation for workers and efficiently cleaning the mold end faces in a small space. Embodiment 2:

[0028] Combination Figure 2-Figure 4 As shown, based on the embodiment 1, a slot is provided on the outside of the sliding sleeve 250, and the progressive screw rod 230 passes through the column head on the inner side of the support plate 240 and is adapted and snapped into the slot; The hydraulic component 260 is fixedly installed inside the sliding sleeve 250 , a sliding groove is provided at the bottom of the supporting plate 240 , and the hydraulic sub-rod in the hydraulic component 260 is adapted to penetrate directly below the sliding groove.

[0029] By controlling the rotating wheel at the outer end of the progressive screw 230, the progressive screw 230 will extend along the inside of the screw sleeve 220, and the column head at the inner end of the progressive screw 230 will control the sliding sleeve 250 to extend at a uniform speed along the inner side of the support plate 240. At this time, the hydraulic component 260 installed inside the sliding sleeve 250 can drive the suspension 270 and the ring rail 280 to adjust the spacing along the outside of the mold. At this time, the ring rail 280 can provide multi-angle position control for the two sets of mold end grinding mechanisms 500 after flipping. At this time, the two sets of mold end grinding mechanisms 500 after flipping can be quickly flipped without being disturbed by the edges and corners of the mold. Embodiment three:

[0030] Combination Figure 5-Figure 11 As shown, based on the embodiment 1, the lifting assembly 310 includes a beam rail 311 horizontally placed just above the mold, three end columns 312 fixedly mounted on the beam rail 311, and three sliding sleeves 313 movably mounted outside the three end columns 312; A slideway is provided inside the beam rail 311, and symmetrically distributed transverse grooves are provided on both sides of the beam rail 311. A booster motor 330 and an extended screw rod 340 installed on the transmission shaft inside the booster motor 330 are installed at one end of the bottom of the beam rail 311. A flip motor 320 is fixedly installed on the top of the beam rail 311, and the gear on the transmission shaft inside the flip motor 320 is adapted to mesh with the tooth opening outside the ring rail 280; The pressure-bearing assembly 350 includes a pulley 353 movably mounted in a slideway inside the beam rail 311, and guide rods at both ends of the pulley 353 respectively penetrate into the transverse grooves on both sides of the beam rail 311, and a clamp seat 351 is arranged outside the pulley 353, and a column head 352 is arranged inside the clamp seat 351; A threaded hole adapted to fit the extended screw rod 340 is formed inside the column head 352 .

[0031] By movably installing the clamp seat 351 and the pulley 353 inside the beam rail 311, when the booster motor 330 is started, its internal transmission shaft will drive the extension screw 340, and the column head 352 and the clamp seat 351 will extend at a uniform speed along the outside of the extension screw 340. At this time, the pressure-bearing component 350 placed horizontally in the beam rail 311 can drive the chip removal mechanism 400 and the two sets of die end grinding mechanisms 500 to fully grind the end face of the closed mold, and the size of the grinding head 540 close to the upper mold can be selected according to the width of its cross section, and the size of the other grinding head 540 does not need to be limited, so the end face of the mold is fully cleaned during the lateral movement of the two grinding heads 540. Embodiment 4:

[0032] Combination Figure 7-Figure 11As shown, on the basis of Example 1, a rectangular hole is opened in the middle of the inner cavity of the wind bin 410, and a guide plate 430 is arranged in the middle of the rectangular hole, and arc surfaces for guiding waste chips are opened on both sides of the guide plate 430; The top of the wind bin 410 is equipped with an energy supply box 450 and a servo motor 440, and the energy supply box 450 is connected to the poles on the servo motor 440 through a wire; Two symmetrically distributed driving screws 460 are installed at both ends of the transmission shaft of the servo motor 440; An air outlet is provided on the end of the dust collecting bin 510 away from the wind bin 410, and the dust collecting bin 510 is made of stainless steel. A cylindrical hole is provided at one end of the dust collecting bin 510, and an elliptical hole is provided at the other end of the dust collecting bin 510. A linkage shaft 570 is disposed in the elliptical hole, and the linkage shaft 570 is composed of a deflection gear, a column and a gear plate; The rod body at the top of the grinding head 540 penetrates into the interior of the first bearing 530, and the rod body at the top of the grinding head 540 is provided with symmetrically distributed oil guide grooves, and a gear ring is provided on the rod body at the top of the grinding head 540; The gear ring inside the grinding head 540 and the gear disk inside the linkage shaft 570 are connected to each other by a chain 580; The rod at the top of the grinding head 540 is adapted to penetrate into the oil drain tank 552 , and the rod at the top of the grinding head 540 is pressed against the bottom of the plug pad 554 .

[0033] By installing two dust collecting bins 510 at both ends of the wind bin 410, the wind bin 410 and the inner cavities of the two dust collecting bins 510 are in a connected state. When the dust exhaust terminal 420 is connected to the wind bin 410, as the dust exhaust terminal 420 discharges air outward, high-pressure airflow will be generated in the inner cavities of the two dust collecting bins 510. At this time, the waste chips raised on the end faces of the two molds can be sucked outward by the high-pressure airflow. Then, the two external oil pipes are connected to the end pipes of the two oil storage pipes 551 respectively. As the two external oil pipes inject different oils in sequence, the grinding head 540 driven by the chain 580 can grind the end surface of the mold to obtain oil infiltration, thereby improving the smoothness of the end surface of the mold. After the end surface of the mold is polished, the anti-rust oil is poured along the grinding head 540 to the surface of the mold, and the gasket at the bottom of the grinding head 540 is replaced, so that the surface of the mold can be fully coated with the anti-rust oil without being damaged, thereby improving the maintenance of the mold surface.

[0034] The working principle and use process of the present invention are as follows: due to the increase in humidity and temperature of the environment in which the traditional two-color injection molding machine is located during long-term use, the end faces of the upper mold and the lower mold inside the injection molding machine will be corroded. In severe cases, a large number of rust spots will be generated on the surface of the mold. Affected by the space in which the mold of the injection molding machine is set, workers' cleaning of rust stains on the end faces of the mold will be hindered. In order to reduce the difficulty of workers in cleaning the end faces of the mold and increase the interference of rust slag falling on the shaping of the molten material, the device is set on the top plate of the traditional two-color injection molding machine.

[0035] By installing the support plate 240 in the slide groove at the top of the top plate 210, and setting two symmetrically distributed return compression springs 290 on the inner side of the support plate 240, the sliding sleeve 250 set in the middle of the two return compression springs 290 will provide a stable support force for the hydraulic component 260. When the progressive screw rod 230 is controlled to rotate along the screw sleeve 220, the sliding sleeve 250 pushed by the inner end of the progressive screw rod 230 will control the hydraulic component 260, the suspension 270 and the ring rail 280 to perform fine adjustment along the outside of the mold as a whole. At this time, the three ends set on the inner side of the beam rail 311 The column 312 and the three sliding sleeves 313 are supported on the inner side of the ring rail 280, and the gear on the internal transmission shaft of the flip motor 320 installed on the top of the beam rail 311 can engage with the teeth on the outside of the ring rail 280. At this time, the beam rail 311 as a whole can be stably pressed on the ring rail 280. At this time, the pressure-bearing component 350 set in the beam rail 311 can drive the chip removal mechanism 400 and the two sets of die end grinding mechanisms 500 to be suspended on the end surface of the top of the mold. In the initial state, the two sets of die end grinding mechanisms 500 are attached to the end surfaces of the two molds after they are attached.

[0036] When the hydraulic component 260 is running, its internal hydraulic sub-rod will cause the ring rail 280 and the two sets of die end grinding mechanisms 500 to drop appropriately as a whole. At this time, the two grinding heads 540 can press the end faces of the upper die and the lower die. At the same time, the rod body on the top of the grinding head 540 will push the plug pad 554 in the opposite direction to extend toward the inner cavity of the oil drain bin 552. At this time, after the oil storage pipe 551 and the oil drain bin 552 are connected, the external oil pipe is connected to the upper end of the oil storage pipe 551. The transferred oil will drip from the hole at the bottom of the oil drain bin 552 along the rod body on the top of the grinding head 540, and will eventually be accompanied by the polishing of the die end face after rust removal by the rotating grinding head 540. After the oil is replaced, the die end face can be polished by adding anti-rust oil for coating.

[0037] According to the instruction manual Figure 1As shown in , a grinding head 540 close to the upper mold can be set according to the width of the outer end face of the mold, while the specifications of the other grinding head 540 arranged on the lower mold are not limited. As the booster motor 330 runs and drives the extension screw 340, the pressure-bearing component 350 will drive the two sets of mold end grinding mechanisms 500 to grind along the end faces of the two molds, and when the dust exhaust end head 420 discharges air to the outside, the air vents opened at the outer ends of the two dust suction bins 510 can suck out the rust residue raised on the end faces of the mold. After the rust residue is sucked out, the mold end face is processed according to the above-mentioned oil polishing and oil coating methods. As the flipping motor 320 drives the propulsion mechanism 300 and the two sets of mold end grinding mechanisms 500 to rotate along the outside of the ring rail 280, the hydraulic sub-rod in the hydraulic component 260 drives the ring rail 280 as a whole to rise and fall along the mold, and the two sets of flipped mold end grinding mechanisms 500 can adapt to the four end faces of the two molds.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
