Description

Technical Field

[0001] The present invention relates to the technical field of injection molding, in particular to an injection molding device for processing plastic products. Background Art

DETAILED DESCRIPTION

[0028] The technical solution provided by the present invention will be further described below with reference to the accompanying drawings and according to specific implementation methods.

[0029] like Figures 1 to 10As shown, an injection molding device for processing plastic products includes an injection molding base 1, the injection molding base 1 includes a bottom plate 101, and multiple pairs of main support rods 106 are fixedly installed on the bottom plate 101. Each pair of main support rods 106 are parallel to each other. A molding mechanism 2 is fixedly installed on the injection molding base 1. The molding mechanism 2 includes a top support gear 201, and the top support gear 201 is longitudinally rotatably installed on the top of the main support rod 106. The molding mechanism 2 includes a bottom support gear 223, and the bottom support gear 223 is longitudinally rotatably installed in the middle of the main support rod 106. A support conveyor belt 202 is rolled between the two top support gears 201 and the two bottom support gears 223. The two support conveyors rolling on the same pair of main support rods 106 are rotated. A plurality of mold positioning frames 203 are fixedly installed between the conveyor belts 202, and the rolling directions of the mold positioning frames 203 on the two pairs of adjacent main support rods 106 are opposite. A round-headed tooth plate 224 is fixedly installed at the bottom of the mold positioning frame 203, and the round-headed tooth plates 224 at the bottom of the two pairs of adjacent mold positioning frames 203 are meshed with each other. An injection half mold 204 is installed in the mold positioning frame 203 for horizontal sliding, and a tension spring is fixedly installed between the injection half mold 204 and the mold positioning frame 203. The injection half mold 204 is divided into a left half mold and a right half mold, which are respectively installed in the mold positioning frames 203 on the two pairs of adjacent main support rods 106. The injection half molds 204 between the two pairs of adjacent main support rods 106 are in contact with each other, and a semi-arc feed port is fixedly installed on the top of the injection half mold 204. After the two injection mold halves 204 are spliced ​​together, a feed port is formed to transfer injection material into the mold formed by splicing the two injection mold halves 204. An air inlet groove 222 is provided inside and outside the injection mold halves 204. An air delivery hole is provided in the air inlet groove 222. The air delivery hole is connected to the inner side of the air inlet groove 222 and is used to inject air into the mold formed by splicing the injection mold halves 204 after injection molding, so that the injection molded part is separated from the inner wall of the injection mold halves 204, which is convenient for subsequent demolding. A detection rotating plate 220 is installed on the inner side of the air delivery hole of the injection mold halves 204 for horizontal rotation. A torsion spring is fixedly installed between the detection rotating plate 220 and the injection mold halves 204. A detection contact is provided on the inner side of the air delivery hole on the air inlet groove 222. The detection point is connected to the external detection system. The detection rotating plate 220 and the detection contact are connected. The detection rotating plate 220 is driven by the torsion spring to maintain a certain tilting angle on the injection half mold 204. When there is an injection molded part in the injection half mold 204, the injection molded part presses the detection rotating plate 220 to make it fit with the detection contact. After the injection molded part is separated, the detection rotating plate 220 is tilted again by the torsion spring to a certain angle, so as to detect whether the injection molded part in the injection half mold 204 is normally demolded. A pair of switch sliders 219 are longitudinally slidably installed in the injection half mold 204. The switch sliders 219 are respectively longitudinally slidably installed on the upper and lower sides of the air inlet groove 222. Compression springs are fixedly installed between the outer ends of the switch slider 219 and the injection half mold 204. The two switch sliders 219 are in contact with each other and are used to control the opening and closing of the air supply hole.This prevents the injection molding material from flowing out of the air delivery holes on the air inlet groove 222. At the same time, when demoulding is required, the air pressure generated by the air injected into the air inlet groove 222 can push the switch slider 219 open for demoulding.

[0030] like Figures 1 to 10 As shown, a cover plate 210 is fixedly mounted on the main support rod 106, and an adjusting motor 211 and a driving motor 213 are fixedly mounted on both ends of the cover plate 210. The cover plates 210 fixedly mounted on two pairs of adjacent main support rods 106 are installed in opposite directions, and the installation positions of the adjusting motor 211 and the driving motor 213 are relative. The driving motor 213 is fixedly connected to the top support gear 201, and is used to drive the support conveyor belt 202 to roll, and to make the support conveyor belts 202 on the two adjacent pairs of main support rods 106 roll in different directions, so that the mold positioning frame 203 and the injection half mold 204 on the two adjacent support conveyor belts 202 can be aligned and spliced ​​with each other to form a conveyor belt for injection molded parts.

[0031] like Figures 1 to 10 As shown, a positioning groove is provided on the bottom of the outer side of the injection mold half 204, a pair of positioning support rods 107 are fixedly installed on the bottom plate 101, and a pair of support wheels 205 are longitudinally rotatably installed on the positioning support rod 107. The two support wheels 205 are respectively fixedly installed on the inner side of the main support rod 106 and are in the same straight line position as the main support rod 106. A support belt 206 is rotatably installed between the two support wheels 205, and a support push rod 207 is horizontally slidably installed on the support belt 206. A compression spring is fixedly installed between the support push rod 207 and the support belt 206, and the support push rod 207 is in contact with the injection mold half 20 4. The bottom plate 101 is fixedly mounted with a support frame 108, which is supported on the inner circle of the support belt 206. The support push rod 207 contacts and cooperates with the positioning groove on the injection mold half 204 to push the injection mold half 204 to slide outward on the mold positioning frame 203, so that the two injection mold halves 204 are spliced ​​together to form a mold. At the same time, when the support conveyor belt 202 rolls and drives the mold positioning frame 203 to move, the support belt 206 is driven to roll synchronously through the cooperation of the support push rod 207 and the positioning groove at the bottom of the injection mold half 204, thereby improving the stability of the equipment operation.

[0032] like Figures 1 to 10As shown, a gas delivery rod 217 is fixedly installed between the top support gear 201 and the bottom support gear 223, and a gas delivery connector 218 is provided on the gas delivery rod 217, which contacts and cooperates with the gas inlet groove 222. An air inlet is provided on the gas delivery rod 217, and the air inlet on the gas delivery rod 217 is connected to the gas delivery connector 218. A second support ring 209 and a first support ring 208 are rotatably installed on the top support gear 201, and a ventilation groove is fixed on the second support ring 209. The ventilation groove on the second support ring 209 contacts and cooperates with the air inlet of the gas delivery rod 217. A gear is fixedly installed on the outer ring of the second support ring 209, and an adjusting motor 211 is fixedly installed on the cover plate 210. An adjusting motor 211 is fixedly installed on the adjusting motor 211. The segment gear 212 and the adjusting gear 212 are engaged with the gear on the second support ring 209 to limit the rotation angle of the second support ring 209 on the top support gear 201. When the driving motor 213 drives the mold positioning frame 203 to roll to the demolding area, air is injected into the air delivery rod 217 through an external air pump, and the air is delivered to the air delivery hole in the air inlet groove 222 through the air delivery connector 218 to demold the injection molded part in the injection half mold 204. At the same time, the adjusting motor 211 is started to drive the adjusting gear 212 to rotate, and the rotation of the adjusting gear 212 drives the second support ring 209 to rotate, thereby adjusting the position of the ventilation groove on the second support ring 209, so that the demolding position of the injection molded part can be changed as needed.

[0033] like Figures 1 to 10 As shown, a cooling groove 221 is provided on the outside of the injection half mold 204, and a plurality of cooling support rods 109 are fixedly installed on the bottom plate 101. The cooling support rods 109 are fixedly installed in the same straight line position as the two main support rods 106. A first transmission disc 214 and a second transmission disc 215 are longitudinally rotatably installed on the cooling support rods 109. A gear pattern is provided on the inside of the support conveyor belt 202. Gears are fixedly installed on the top of the first transmission disc 214 and the second transmission disc 215. The gears on the first transmission disc 214 and the second transmission disc 215 are aligned with the inner side of the support conveyor belt 202. The gear patterns are engaged, and a plurality of cooling rods 216 are installed on the first transmission disc 214 and the second transmission disc 215 for horizontal sliding. The cooling rods 216 on the first transmission disc 214 and the second transmission disc 215 are staggered at different heights, and the cooling rods 216 are in contact with the cooling groove 221. The first transmission disc 214 and the second transmission disc 215 are driven to rotate on the inner circle of the support conveyor belt 202 by the rolling of the support conveyor belt 202, so that the cooling rods 216 are in contact with the cooling groove 221 for heat dissipation, which is used to cool and mold the injection half mold 204 during the movement.

[0034] like Figures 1 to 10As shown, a feeding telescopic rod 105 is fixedly mounted on the bottom plate 101, and the feeding telescopic rod 105 is fixedly mounted between two pairs of main support rods 106, and is fixedly mounted at the starting position of the rolling direction of two adjacent supporting conveyor belts 202. A feeding mechanism 3 is fixedly mounted on the feeding telescopic rod 105, and the feeding mechanism 3 includes a feeding bracket 301, and the feeding bracket 301 is fixedly mounted on the top of the feeding telescopic rod 105. A feeding pipe 302 is fixedly mounted on the top of the feeding bracket 301, and the feeding pipe 302 is connected to an external feeding pump. The bottom front end of the feeding bracket 301 The top of the joint base 303 is fixedly installed, the bottom of the joint base 303 is fixedly installed with a joint pipe 304, the bottom of the joint base 303 is fixedly installed with a clamping plate 305, the clamping plate 305 is fixedly installed on the outside of the joint pipe 304, and is spaced a certain distance from the joint pipe 304. The semi-arc feed port on the injection half mold 204 is slidably matched with the gap between the joint pipe 304 and the joint pipe 304, and is used to prevent the two injection half molds 204 from separating due to the large internal pressure when injecting the injection plastic. The bottom of the joint pipe 304 slides longitudinally The injection joint 306 is dynamically installed, and the outer wall of the injection joint 306 is provided with a discharge hole for injecting plastic into the injection half mold 204 from the side. The injection joint 306 is connected to the feed pipe 302. When injection molding is required in the injection half mold 204, the injection mechanism 3 is driven down by starting the injection telescopic rod 105, so that the joint pipe 304 extends into the feed port at the top of the injection half mold 204, and the clamping plate 305 wraps the semi-arc feed port at the top of the injection half mold 204 on both sides. Then, the injection pump is started to inject plastic into the injection half mold 204. When When the injection plastic in the injection half mold 204 is full, the injection molding at the top of the injection half mold 204 will push the support belt 206 to retract into the joint pipe 304, so that the joint pipe 304 covers the discharge hole on the outer wall of the injection joint 306 to prevent the injection plastic from overflowing. At the same time, if a molded injection molded part fails to be demolded normally and remains inside the injection half mold 204, when the joint pipe 304 is extended into the feed port at the top of the injection half mold 204, the injection joint 306 will be pushed back into the joint pipe 304 by the injection molded part and injection molding cannot be carried out, thereby avoiding damage to the mold.

[0035] like Figures 1 to 10 As shown, a plurality of discharge baffles 102 are fixedly mounted on the bottom plate 101, a discharge belt 103 is rotatably mounted on the discharge baffle 102, a discharge motor 104 is fixedly mounted on the discharge baffle 102, the discharge motor 104 is connected to the discharge belt 103, and the discharge baffle 102 is fixedly mounted at the end of the rolling direction of two adjacent support conveyor belts 202, opposite to the injection telescopic rod 105, for receiving injection molded parts.

[0036] Working principle: By starting the drive motor 213, the top support gear 201 is driven to rotate on the main support rod 106, and the support conveyor belt 202 is driven to roll between the top support gear 201 and the bottom support gear 223. At the same time, the rotation directions of the top support gears 201 on the two adjacent pairs of main support rods 106 are opposite. At the same time, the two injection half molds 204 are aligned and spliced ​​with each other through the push of the support push rod 207 to form an injection mold.

[0037] Start the injection telescopic rod 105 to drive the injection mechanism 3 to descend, so that the joint pipe 304 extends into the feed port at the top of the injection half mold 204, and the semi-arc feed port at the top of the injection half mold 204 is clamped by the clamping plate 305, and start the external injection pump to inject injection material into the injection half mold 204 through the injection joint 306. After the injection is completed, the injection half mold 204 is driven by the support conveyor belt 202 to move toward the demolding position.

[0038] During the movement, the injection mold half 204 is cooled by the cooling rod 216, so that the injection material in the injection mold half 204 is gradually formed. When the injection mold half 204 moves to the end of the conveyor belt, the two injection mold half 204 are no longer pushed by the support push rod 207, so that the two injection mold half 204 are separated from each other by the tension spring. At the same time, the air supply connector 218 contacts and cooperates with the air inlet groove 222, and air is injected into the air inlet groove 222 by starting the external air pump. The switch slider 219 is opened by air pressure to inject air into the injection mold half 204. The molded injection part is separated from the injection mold half 204 by air pressure, and is collected by the discharge baffle 102 and output through the discharge belt 103.

[0039] During this period, the rotation angle of the second support ring 209 can be adjusted by starting the adjustment motor 211, and the position of the ventilation groove on the second support ring 209 can be changed, so as to facilitate the advance or delay of the time of separating the injection molded parts according to the size of the injection molded parts, change the position where the injection molded parts fall, and facilitate the collection of the discharge baffle 102.
