Description

Technical Field

[0001] The present invention relates to the field of injection molding equipment, and particularly to an injection molding equipment for the production of power covers and a usage method thereof. Background Art

[0002] Power covers are widely used in power facilities for cable trench laying in environments such as power transmission lines, substations, and power plants. Power covers are usually injection molded using corrosion-resistant composite resin materials and need to be produced and processed by special injection molding equipment during the production process.

[0003] The existing patent (Publication No.: CN118219489B) discloses a rapid injection molding equipment for injection molded products, including a machine body, and further includes a glue injection device. A feeding device is fixedly installed on the top of the machine body. In the process of implementing this solution, the following problems in the prior art are found to have not been well solved: 1. During the use of the injection molding equipment, the production of the next injection molded part can only be carried out after the previous injection molded part is disassembled, resulting in low work efficiency; 2. Usually, the glue injection port of the injection molding equipment is far from the position of the glue injection screw rod. After the injection molding stops, a large amount of injection molding raw material will adhere to the position of the glue injection port. This injection molding raw material is prone to solidification. During the use of this injection molding equipment, only the position of the glue injection port can be sealed by a sealing block, and it is difficult to discharge the excess raw material at the position of the glue injection port, reducing the occurrence of solidification of the injection molding raw material, thereby affecting the quality of subsequent injection molding production. Summary of the Invention

One end of the pressing rod is movably inserted through the surface of the movable sleeve. The end of the glue injection pipe away from the discharge chute is fixedly connected with a stop block that cooperates with the pressing rod;

[0016] A rectangular plate is fixedly connected to the surface of the pressing rod. There are eight rectangular plates, and the eight rectangular plates are fixedly connected to the surface of the pressing rod at equal intervals along the circumference. Every four rectangular plates are set as a group, and the two groups of rectangular plates are arranged in a staggered manner. A waist-shaped groove is formed in the middle of the rectangular plate. A sliding pin is slidably connected inside the waist-shaped groove. A U-shaped scraping plate is fixedly connected between the two ends of the sliding pin. The U-shaped scraping plate is movably inserted through the surface of the glue injection pipe;

[0018] Preferably, the end of the U-shaped scraping plate away from the glue injection pipe is an arc surface. Adjacent two U-shaped scraping plates are lapped. A chamfer is formed on the surface of the U-shaped scraping plate.

[0019] Preferably, the cross bar is T-shaped, and a counterbore that cooperates with the cross bar is formed on the surface of the cover plate punch.

[0020] Preferably, positioning pin sleeves are fixedly connected to the four sides of the cover plate die, and positioning pin shafts are fixedly connected to the four sides of the cover plate punch. The four positioning pin shafts correspond to the four positioning pin sleeves one by one;

[0021] Discharge chute grooves are formed on the front and back sides of the injection molding machine bracket. The two discharge chute grooves correspond to the two cover plate dies one by one.

[0022] A use method of an injection molding device for power cover plate production includes the following steps:

[0023] S1. When in use, first start the drive motor to drive the turntable and the adjusting pin to rotate. At this time, during the sliding cooperation of the adjusting pin and the adjusting plate, the adjusting plate drives the support ring to move back and forth on the surface of the support pipe. When the support ring moves forward to the limit position, the support ring will press against the limit ring on the front side of the support pipe and drive the support pipe to move forward on the surface of the sliding rod. On the contrary, when the support ring moves backward to the limit position, the support ring will press against the limit ring on the rear side of the support pipe and drive the support pipe to move backward on the surface of the sliding rod. In this way, during the back-and-forth movement of the two support pipes, the support pipes drive the corresponding connecting ring frames, cover plate dies and cover plate punches to move synchronously;

[0024] S2. During the forward movement of the support tube, the cover plate die on the front side of the support tube is synchronously moved forward with the cover plate punch through the guide rod. At the same time, under the action of the guide spring, the cover plate punch and the cover plate die are gradually separated to realize the mold opening action. At this time, the docking sleeve on the cover plate punch releases the pressure on the injection tube, and under the elastic recovery of the compression spring, the injection tube moves toward the side wall of the cover plate punch. At this time, the pressure rod on the injection tube releases the contact with the cleaning ring on the inner wall of the adjacent discharge trough, so that the cleaning ring moves toward the outside of the discharge trough under the action of the return spring. Then the cleaning ring cooperates with the cushion rod to move the sealing cone block to the port position of the discharge trough to seal the discharge trough. At the same time, the moving cleaning ring scrapes the inner wall of the discharge trough to reduce the injection molding material adhering to the inner wall of the discharge trough.

[0025] S3. During the forward movement of the injection tube at the front side of the injection molding machine bracket, the movable sleeve inside the injection tube is restricted at the outlet position of the discharge trough by the T-shaped connecting rod. After the injection tube moves forward, the block on the injection tube releases the pressure on the extrusion rod inside the movable sleeve. Under the elastic recovery of the extrusion spring, the extrusion rod moves inside the movable trough with the rectangular plate. At this time, the waist groove on the rectangular plate cooperates with the sliding pin on the U-shaped scraper to slide. Then the U-shaped scraper moves along the side wall of the movable sleeve toward the inner wall of the injection tube, so that eight U-shaped scrapers form a ring and are attached to the inner wall of the injection tube. As the injection tube moves, the eight scrapers scrape off the injection molding materials remaining on the inner wall of the injection tube, and the scraped injection molding materials fall into the Y-shaped unloading plate for discharge.

[0026] S4. At the same time, the cover plate die installed on the rear side of the support tube through the connecting ring frame moves forward and moves toward the feeding dragon pipe with the cover plate punch. At this time, the cover plate die and the cover plate punch behind the injection molding machine bracket are molded together and move with the docking sleeve and the adjacent injection tube to the discharge slot position of the side wall of the feeding dragon pipe, so that one end of the injection tube is plugged and sealed with the corresponding discharge slot, and the other end of the injection tube is sealed with the docking sleeve on the corresponding cover plate punch. In this process, the cleaning ring inside the discharge slot is pressed and moved by the pressure rod at the end of the injection tube, so that the cleaning ring is released from the sealing state with the discharge slot through the pad rod and the sealing cone block. At the same time, the stopper on the injection tube is pressed against the extrusion rod position on the surface of the corresponding movable sleeve, so that the rectangular plate on the extrusion rod slides with the U-shaped scraper, and the U-shaped scraper moves toward the side wall of the movable sleeve, so that the inside of the injection tube is completely penetrated for injection molding, so that the two molds before and after the injection molding machine bracket can perform continuous power cover injection molding production in a staggered manner.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the present invention, through the coordinated use of components such as an injection molding machine bracket, a feeding auger pipe, and an adjustment mechanism, during the operation of the adjustment mechanism, the cover die and the cover punch on the front and rear sides of the injection molding machine bracket are matched with the feeding auger pipe in a misaligned manner for injection molding processing. This misaligned injection molding method can achieve continuous injection molding production and improve work efficiency.

[0029] In the present invention, through the coordinated use of components such as a feeding auger pipe, an adjustment mechanism, and a discharge switching mechanism, during the mold opening operation of the cover die and the corresponding cover punch, under the operation of the discharge switching mechanism, the excess injection molding raw materials in the discharge groove and the inner wall of the injection pipe can be discharged, reducing the occurrence of solidification of the injection molding raw materials inside the injection pipe and improving the quality of subsequent injection molding.

Detailed implementation manner

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 to 11 , the present invention provides a technical solution: an injection molding device for the production of power covers, including an injection molding machine bracket 1, a drive motor 2 is fixedly connected to the inner bottom surface of the injection molding machine bracket 1, and a turntable 3 is fixedly connected to the rotating end of the drive motor 2. It should be noted that: a groove is provided on the inner bottom surface of the injection molding machine bracket 1, and the drive motor 2 is fixedly connected inside the groove.

[0044] Both sides of the inner wall of the injection molding machine bracket 1 are fixedly connected with slide bars 4, a support tube 5 is slidably connected to the middle of the slide bars 4, and an adjustment mechanism 6 is movably connected between the surfaces of the two support tubes 5 and the top of the turntable 3. It should be noted that: both ends of the slide bar 4 are fixedly connected with mounting blocks, and the slide bar 4 is fixedly connected to the inside of the injection molding machine bracket 1 through the mounting blocks.

[0045] Connecting ring frames 7 are symmetrically fixedly connected to the surface of the support tube 5, a cover die 8 is fixedly connected between the two opposite connecting ring frames 7, and a cover punch 9 is movably connected to one side of the cover die 8.

[0046] On the right side of the inner wall of the injection molding machine bracket 1, a feeding auger pipe 10 is fixedly connected. The feeding auger pipe 10 is arranged between two cover plate punches 9. At the left end of the feeding auger pipe 10, a discharge switching mechanism 11 is provided. The two ends of the discharge switching mechanism 11 correspond to the two cover plate punches 9 one by one. On the left side of the injection molding machine bracket 1, a Y-shaped discharge plate 12 that cooperates with the discharge switching mechanism 11 is fixedly connected. It should be noted that: after the discharge switching mechanism 11 discharges the excess injection molding raw materials, the excess injection molding raw materials will fall into the interior of the Y-shaped discharge plate 12 and then be discharged. The Y-shaped discharge plate 12 is arranged above the support pipe 5 to avoid interference.

[0047] On both sides of the cover plate punch 9, guide rods 13 are symmetrically and fixedly connected. On both sides of the cover plate die 8, guide blocks 14 are symmetrically and fixedly connected. The guide rods 13 are movably inserted through the middle parts of the corresponding guide blocks 14. A guide spring 15 that cooperates with the guide rod 13 is movably sleeved on the middle part of the guide rod 13. It should be noted that: the cooperation of the guide rod 13, the guide block 14 and the guide spring 15 facilitates the mold opening operation of the cover plate punch 9 and the cover plate die 8, and the discharging operation after mold opening is an existing technology, which will not be described in detail here.

[0048] In this embodiment, as Figures 1 to 11 shown, the adjusting mechanism 6 includes an adjusting pin 601, and the adjusting pin 601 is eccentrically installed on the top of the turntable 3.

[0049] Support rings 602 are slidably connected to the middle parts of the two support pipes 5. A connecting plate 603 is fixedly connected between the bottoms of the two support rings 602. An adjusting groove 604 is formed in the middle of the connecting plate 603. The connecting plate 603 is slidably connected to the surface of the adjusting pin 601 through the adjusting groove 604. It should be noted that: when the turntable 3 drives the eccentrically arranged adjusting pin 601 to rotate, the adjusting groove 604 on the connecting plate 603 cooperates with the adjusting pin 601 to slide, so that the connecting plate 603 drives the support ring 602 to slide reciprocally on the surface of the support pipe 5.

[0050] Limiting rings 605 that cooperate with the support rings 602 are symmetrically and fixedly connected to both sides of the support pipe 5. The two limiting rings 605 are arranged between the two connecting ring frames 7 on the same side.

[0051] In this embodiment, as Figures 1 to 11 shown, the distance that the support pipe 5 slides on the surface of the sliding rod 4 is set to be twice the distance from the axis of the adjusting pin 601 to the axis of the turntable 3. It should be noted that: when the turntable 3 drives the adjusting pin 601 to rotate one circle, the support pipe 5 can slide reciprocally on the surface of the sliding rod 4 once. During this reciprocating sliding process, the connecting ring frame 7 on the support pipe 5 drives the corresponding cover plate punch 9 to move, so that the two cover plate punches 9 at the front and rear positions on the injection molding machine bracket 1 can alternately cooperate with the discharge switching mechanism 11 on the feeding auger pipe 10 for injection molding processing, thereby realizing continuous injection molding operations.

[0052] In this embodiment, Figures 1 to 11 As shown, the discharge switching mechanism 11 includes a discharge trough 1101, and there are two discharge troughs 1101. The two discharge troughs 1101 are symmetrically opened at the left end of the feeding dragon pipe 10. The inner wall of the discharge trough 1101 is fixedly connected with four cushion blocks 1102 at equal intervals along the circumference. The surface of the cushion block 1102 is slidably connected with a cushion rod 1103. A cleaning ring 1104 is fixedly connected between one ends of the four cushion rods 1103. The cleaning ring 1104 is arranged inside the discharge trough 1101. The middle movable sleeve 1113 of the cushion rod 1103 is connected with a return spring 1105 matched with the cleaning ring 1104. A sealing cone block 1106 is fixedly connected between the other ends of the four cushion rods 1103. The sealing cone block 1106 is arranged at the port position of the discharge trough 1101. It should be noted that: the discharge trough 1101 is located at one end of the dragon pipe and is provided with a conical chamfer that cooperates with the sealing cone block 1106; when the surface of the cleaning ring 1104 is released from the pressure state, under the action of the return spring 1105, the pad rod carries the cleaning ring 1104 to move inside the discharge trough 1101 to clean the inner wall of the discharge trough 1101, and at the same time, the pad rod 1103 carries the sealing cone block 1106 and cooperates with the conical chamfer position of the discharge trough 1101 to seal.

[0053] The two discharging troughs 1101 are symmetrically and fixedly connected with cross bars 1107 at their opposite ends, and a conical sleeve 1108 is slidably connected between two adjacent cross bars 1107. A compression spring 1109 that cooperates with the conical sleeve 1108 is movably sleeved on the surface of the cross bar 1107, and a glue injection tube 1110 is fixedly connected inside the conical sleeve 1108. One end of the glue injection tube 1110 is symmetrically and fixedly connected with a pressure rod 1111 that cooperates with the cleaning ring 1104. It should be noted that: the inner wall of the discharge trough 1101 away from the end of the feeding dragon pipe 10 is set to be a cone that matches the cone sleeve 1108; the length of the pressure rod 1111 is set to 0.8 times the length of the discharge trough 1101. When the injection tube 1110 moves toward the discharge trough 1101 and seals with the discharge trough 1101, the pressure rod 1111 will press against the surface of the cleaning ring 1104 inside the discharge trough 1101, so that the cleaning ring 1104 moves with the pad rod 1103 and the sealing cone block 1106. At this time, the sealing cone block 1106 releases the seal on the discharge trough 1101.

[0054] The inner wall of the discharge chute 1101 is fixedly connected with a T-shaped connecting rod 1112. One end of the T-shaped connecting rod 1112 is fixedly connected with a movable sleeve 1113. The movable sleeve 1113 is movably inserted into the interior of the adjacent glue injection tube 1110. An activity groove 1114 is formed inside the movable sleeve 1113. The inner wall of the activity groove 1114 is fixedly connected with a compression spring 1115. One end of the compression spring 1115 is fixedly connected with a compression rod 1116. One end of the compression rod 1116 is movably inserted through the surface of the movable sleeve 1113. The end of the glue injection tube 1110 away from the discharge chute 1101 is fixedly connected with a stop block 1117 that cooperates with the compression rod 1116.

[0055] A rectangular plate 1118 is fixedly connected to the surface of the compression rod 1116. There are eight rectangular plates 1118, and the eight rectangular plates 1118 are fixedly connected to the surface of the compression rod 1116 at equal intervals along the circumference. Every four rectangular plates 1118 are set as a group, and the two groups of rectangular plates 1118 are arranged in a staggered manner. A waist-shaped groove 1119 is formed in the middle of the rectangular plate 1118. A sliding pin 1120 is slidably connected inside the waist-shaped groove 1119. A U-shaped scraping plate 1121 is fixedly connected between the two ends of the sliding pin 1120. The U-shaped scraping plate 1121 is movably inserted through the surface of the glue injection tube 1110. It should be noted that when the glue injection tube 1110 moves towards the corresponding discharge chute 1101, the stop block 1117 will press against the end of the compression rod 1116 on the surface of the movable sleeve 1113. At this time, the compression rod 1116 drives the rectangular plate 1118 to move. During the sliding process of the cooperation between the waist-shaped groove 1119 and the sliding pin 1120, the U-shaped scraping plate 1121 extends out from the inside of the movable sleeve 1113, and the U-shaped scraping plate 1121 cleans the inside of the moving glue injection tube 1110.

[0056] The side wall of the cover plate punch 9 is fixedly connected with a docking sleeve 1122 that cooperates with the glue injection tube 1110. It should be noted that the interior of the docking sleeve 1122 is a conical surface, the end of the glue injection tube 1110 is conical and is matched with the docking sleeve 1122, and a sealing gasket is arranged at the position of the conical surface to ensure the sealing performance during the cooperation between the cover plate punch 9 and the glue injection sleeve.

[0057] In this embodiment, as Figures 1 to 11 shown, the end of the U-shaped scraping plate 1121 away from the glue injection tube 1110 is an arc surface, and two adjacent U-shaped scraping plates 1121 are overlapped. A chamfer is formed on the surface of the U-shaped scraping plate 1121. It should be noted that this overlapping setting enables the eight U-shaped scraping plates 1121 to form a ring and fit on the inner wall position of the glue injection tube 1110.

[0058] In this embodiment, as Figures 1 to 11As shown, the cross bar 1107 is set to be T-shaped, and a counterbore matching with the cross bar 1107 is formed on the surface of the cover plate punch 9. It should be noted that the counterbore is provided to avoid interference between the cover plate punch 9 and the end of the cross bar 1107 during the injection molding process.

[0059] In this embodiment, as Figures 1 to 11 shown, positioning pin sleeves are fixedly connected to the four sides of the cover plate die 8, and positioning pin shafts are fixedly connected to the four sides of the cover plate punch 9. The four positioning pin shafts correspond to the four positioning pin sleeves one by one.

[0060] Discharge chute are formed on the front and rear sides of the injection molding machine bracket 1, and the two discharge chutes correspond to the two cover plate dies 8 one by one. It should be noted that the discharge chute is provided to facilitate the discharging operation after mold opening.

[0061] In this embodiment, as Figures 1 to 11 shown, a method for using an injection molding device for power cover plate production includes the following steps:

[0062] S1. During use, first start the drive motor 2 to drive the turntable 3 and the adjusting pin 601 to rotate. At this time, during the sliding cooperation between the adjusting pin 601 and the adjusting plate 603, the adjusting plate 603 drives the support ring 602 to reciprocate back and forth on the surface of the support tube 5. When the support ring 602 moves forward to the limit position, the support ring 602 will press against the limit ring 605 at the front side of the support tube 5 and drive the support tube 5 to move forward on the surface of the slide rod 4. On the contrary, when the support ring 602 moves backward to the limit position, the support ring 602 will press against the limit ring 605 at the rear side of the support tube 5 and drive the support tube 5 to move backward on the surface of the slide rod 4. In this way, during the reciprocating back and forth movement of the two support tubes 5, the support tube 5 drives the corresponding connecting ring frame 7, cover plate die 8 and cover plate punch 9 to move synchronously;

[0063] S2. During the forward movement of the support tube 5, the cover die 8 on the front side of the support tube 5 drives the cover punch 9 to move forward synchronously through the guide rod 13. At the same time, under the action of the guide spring 15, the cover punch 9 and the cover die 8 are gradually separated to realize the mold opening action. At this time, the docking sleeve 1122 on the cover punch 9 releases the pressing on the glue injection tube 1110. Under the elastic recovery of the compression spring 1109, the glue injection tube 1110 moves towards the side wall direction of the cover punch 9. At this time, the pressure rod 1111 on the glue injection tube 1110 releases the contact with the cleaning ring 1104 on the inner wall of the adjacent discharge chute 1101, so that the cleaning ring 1104 moves towards the outside direction of the discharge chute 1101 under the action of the return spring 1105. Then, the cleaning ring 1104 cooperates with the cushion rod 1103 to drive the sealing cone block 1106 to move to the port position of the discharge chute 1101 to seal the discharge chute 1101. At the same time, the moving cleaning ring 1104 scrapes the inner wall of the discharge chute 1101 to reduce the injection molding raw materials adhered to the inner wall position of the discharge chute 1101;

[0064] S3.
