Description

Technical Field

[0001] The invention relates to the technical field of injection molding machines, in particular to an intermittent multi-specification plastic injection molding machine. Background Art

[0002] An injection molding machine, also known as an injection molding machine or injection molding machine, is the primary molding equipment used to create plastic products of various shapes from thermoplastics or thermosetting plastics using plastic molding molds. An injection molding machine typically consists of an injection system, a mold clamping system, a hydraulic transmission system, an electrical control system, a lubrication system, a heating and cooling system, and a safety monitoring system. Depending on the arrangement of the injection and clamping mechanisms, injection molding machines can be categorized as vertical, horizontal, or a combination of vertical and horizontal types.

[0003] Intermittent multi-specification plastic injection molding machines can use plastics of various specifications to improve the applicability of the injection molding machine. In addition, intermittent multi-specification plastic injection molding machines can control the amount of plastic injected to avoid excessive use and waste of plastic.

[0004] The role of the mold clamping system in an injection molding machine is to ensure mold closure, opening, and ejection of the product. At the same time, after the mold is closed, sufficient clamping force is applied to the mold to resist the cavity pressure generated by the molten plastic entering the mold cavity, preventing the mold from cracking and causing poor product quality. Vertical injection molding machines are characterized by the mold clamping device and injection device being aligned in a straight line and perpendicular to the ground. However, during demolding, the ejected plastic parts of existing vertical injection molding machines are difficult to remove and often require manual removal. Manual operation is not conducive to continuous production and has high labor costs.

[0034] See also Figures 1 to 7 , the present invention provides a technical solution:

[0035] An intermittent multi-specification plastic injection molding machine, such as Figures 1 to 2 Shown, including:

[0036] L-shaped bracket 1;

[0037] An injection mechanism 2, which is fixedly mounted on the top of the L-shaped bracket 1;

[0038] An injection tube 3, which is fixedly mounted at the bottom of the injection mechanism 2 and is a hose;

[0039] and a mold clamping mechanism 4;

[0040] The mold clamping mechanism 4 is fixedly installed at the lower end of the injection tube 3, and the mold clamping mechanism 4 is conducive to taking out the plastic parts.

[0041] During operation, in the existing vertical injection molding machine, when demoulding, the ejected plastic parts are not easy to fall off and often need to be taken out manually. Manual operation is not conducive to continuous production and has high labor costs. The present invention provides a mold clamping mechanism 4, which can automatically take out the plastic parts, avoid manual removal, is conducive to continuous production, and reduces labor costs.

[0042] As an embodiment of the present invention, Figure 2 As shown, the clamping mechanism 4 includes an upper mold 41, a first lower mold plate 42 and a second lower mold plate 412, the first lower mold plate 42 and the second lower mold plate 412 are provided with mold cavities of the same size and shape, the lower end of the injection tube 3 is fixedly connected with the upper mold 41, the two sides of the upper surface of the upper mold 41 are fixedly connected with the second hydraulic rod 414 by setting a disassembly mechanism 5, and the top of the second hydraulic rod 414 is fixedly connected with a cross plate 413, and the cross plate 413 is fixedly installed on the outer surface of the L-shaped bracket 1, the first lower mold plate 42 is arranged below the upper mold 41, the lower surface of the first lower mold plate 42 is fixedly connected with the second lower mold plate 412, the outer surfaces of the first lower mold plate 42 and the second lower mold plate 412 are fixedly connected with a rotating shaft 411, the other ends of the two rotating shafts 411 are rotatably connected with a fixed plate 43, and the fixed plate 43 is fixedly connected to the L-shaped bracket 1, wherein the rotating shaft 411 on the left side passes through the fixed plate 43 and is fixedly connected with a motor 410;

[0043] A collecting box 47 is fixedly connected to the middle position of the bottom surface of the L-shaped bracket 1, and a telescopic part 48 is fixedly connected to the upper surface of the collecting box 47. A clamping plate 44 is fixedly connected to the upper surface of the telescopic part 48. The first hydraulic rod 49 is symmetrically fixedly connected to the lower surface of the clamping plate 44 on both sides. The lower surface of the first hydraulic rod 49 is fixedly connected to the L-shaped bracket 1, and a connecting pipe 45 is fixedly connected to the outer surface of the telescopic part 48. The other end of the connecting pipe 45 is fixedly connected to the exhaust fan 46, and the exhaust fan 46 is fixedly installed on the bottom surface of the L-shaped bracket 1.

[0044] During operation, in order to facilitate the removal of plastic parts and reduce labor costs, the present invention is used to drive the second hydraulic rod 414 to move downward, and the upper mold 41 fixedly connected to the second hydraulic rod 414 through the disassembly mechanism 5 is thereby moved downward. When the upper mold 41 moves to fit together with the first lower mold plate 42, the second hydraulic rod 414 is stopped from moving downward, and the upper mold 41 moves to fit together with the first lower mold plate 42 to form a closed mold. Then, the plastic particles are fed into the injection mechanism 2 through the feed port 15, and the plastic is injected from the injection molding machine through the injection mechanism 2. The tube 3 enters the mold cavity formed by the upper mold 41 and the first lower mold plate 42. After the plastic part is formed, the second hydraulic rod 414 is driven to move upward, and the upper mold 41 fixedly connected to the second hydraulic rod 414 moves upward accordingly. Then, the motor 410 is connected to the external power supply and driven to rotate the motor 410, and the rotating shaft 411 fixedly connected to the motor 410 rotates accordingly. It should be noted that the output shaft of the motor 410 is fixedly connected to the rotating shaft 411, and the motor 410 is fixedly connected to the fixed plate 43. Similarly, the second hydraulic rod 414 is driven to move upward, and the upper mold 411 fixedly connected to the second hydraulic rod 414 moves upward accordingly. The lower template 42 and the second lower template 412 rotate accordingly. When the first lower template 42 located at the top rotates to the bottom, the first hydraulic rod 49 is driven to move up, and the pressing plate 44 fixedly connected to the first hydraulic rod 49 moves up accordingly. When the pressing plate 44 moves up to fit together with the first lower template 42, the first hydraulic rod 49 is stopped from moving up. At this time, a closed cavity is formed between the first lower template 42, the telescopic part 48 and the collection box 47. Finally, the exhaust fan 46 is connected to the external power supply and the exhaust fan 46 is driven to Working, since the exhaust fan 46 is connected with the first lower template 42, the telescopic part 48 and the collection box 47 to form a closed cavity through the connecting pipe 45, the exhaust fan 46 can draw the cavity into a negative pressure state, so that the plastic parts on the first lower template 42 can be sucked into the collection box 47, so as to remove the plastic parts on the first lower template 42, avoiding manual removal and reducing labor costs. In addition, while taking out the plastic parts, the second lower template 412 rotates to the top, and injection molding can be continued, which is conducive to continuous production.

[0045] As an embodiment of the present invention, Figure 3As shown, the disassembly mechanism 5 includes a T-shaped slider 51, a bolt 52 and a T-shaped slot 53. The lower surface of the second hydraulic rod 414 is fixedly connected to the T-shaped slider 51. The upper surface of the upper mold 41 is provided with a T-shaped slot 53 that is compatible with the T-shaped slider 51. The T-shaped slider 51 is inside the T-shaped slot 53, and the T-shaped slider 51 and the T-shaped slot 53 are fastened together by bolts 52.

[0046] During operation, after the upper mold 41 has been used for a long time, it will naturally wear out and need to be replaced. By setting up the disassembly mechanism 5, when the upper mold 41 needs to be replaced, it is only necessary to unscrew the bolt 52 and then slide the T-shaped slider 51 out of the T-shaped slot 53 to replace the upper mold 41.

[0047] As an embodiment of the present invention, Figure 3 As shown, one side of the T-slot 53 is closed, and the front end of the T-slotted slider 51 is flush with the first lower template 42 and the second lower template 412 .

[0048] During operation, when installing the upper mold 41, it is necessary to align the upper mold 41 with the first lower mold 42 and the second lower mold 412. By setting one side of the T-slot 53 to a closed shape, slide the T-slot slider 51 into the inside of the T-slot 53, so that the rear end of the T-slot slider 51 is against the T-slot 53, and the front end of the T-slot slider 51 is flush with the upper mold 41. Since the front end of the T-slot slider 51 is flush with the first lower mold 42 and the second lower mold 412, the upper mold 41 is flush with the first lower mold 42 and the second lower mold 412.

[0049] As an embodiment of the present invention, Figure 2 As shown, a sealing ring 11 is fixedly connected to the outer edge of the upper surface of the first lower template 42 , the lower surface of the second lower template 412 , and the upper surface of the pressing plate 44 .

[0050] During operation, when the clamping plate 44 is fitted with the first lower template 42 and the second lower template 412, gaps may not be tight enough, causing the exhaust fan 46 to be unable to draw the closed cavity formed by the first lower template 42, the telescopic part 48 and the collection box 47 into a negative pressure state. By fixing the sealing ring 11 on the first lower template 42, the second lower template 412 and the clamping plate 44, the clamping plate 44 can be made to fit more tightly with the first lower template 42 and the second lower template 412 to prevent gaps from occurring.

[0051] As an embodiment of the present invention, Figure 5 As shown, the sealing ring 11 is fixedly embedded with a magnetic strip 12 , and the magnetic strips 12 on the first lower template 42 and the second lower template 412 and the magnetic strip 12 on the pressing plate 44 attract each other.

[0052] During operation, when the sealing ring 11 is pressed between the clamping plate 44 and the first lower template 42 or the second lower template 412, misalignment may occur. By installing a magnetic strip 12 inside the sealing ring 11, the sealing ring 11 can be attracted together to prevent misalignment.

[0053] As an embodiment of the present invention, Figure 4 As shown, a groove 10 adapted to the sealing ring 11 is provided at the outer edge of the lower surface of the upper mold 41 .

[0054] During operation, when the mold is closed, the sealing ring 11 on the first lower template 42 and the second lower template 412 may affect the mold closing, making it impossible for the upper mold 41 and the first lower template 42 or the second lower template 412 to fit together precisely, affecting the quality of the plastic part. By opening a groove 10 on the lower surface of the upper mold 41, when the mold is closed, the sealing ring 11 on the first lower template 42 and the second lower template 412 can enter the groove 10, and the upper mold 41 and the first lower template 42 or the second lower template 412 can fit together precisely.

[0055] As an embodiment of the present invention, Figure 6 As shown, U-shaped plates 6 are provided on both sides of the lower surfaces of the two fixed plates 43, and a slide groove 7 is provided on the outer surface of the fixed plate 43. The top of the U-shaped plate 6 is slidably installed inside the slide groove 7, and a third hydraulic rod 8 is fixedly connected to the outer surface of the U-shaped plate 6. The end of the third hydraulic rod 8 away from the U-shaped plate 6 is fixedly connected to a fixed block 9, and the fixed block 9 is fixedly connected to the fixed plate 43.

[0056] During operation, when the mold is closed, the upper mold 41 exerts downward pressure on the first lower mold 42 and the second lower mold 412, which may cause the first lower mold 42 and the second lower mold 412 to deflect. By setting the third hydraulic rod 8, when the mold is closed, the third hydraulic rod 8 is driven to contract, so that the U-shaped plate 6 moves to the bottom of the first lower mold 42 and the second lower mold 412 to support the first lower mold 42 and the second lower mold 412 to prevent them from deflecting. After the mold is closed, the first hydraulic rod 8 is driven to reset, and the U-shaped plate 6 fixedly connected to the third hydraulic rod 8 is reset accordingly, thereby avoiding the U-shaped plate 6 from obstructing the demoulding operation below during the injection molding of the plastic part after the mold is closed.

[0057] As an embodiment of the present invention, Figure 7 As shown, a buffer pad 13 is fixedly connected to the inner bottom surface of the collection box 47.

[0058] During operation, when plastic parts fall into the collection box 47, they may be damaged, reducing the production quality of the plastic parts. By fixing the buffer pad 13 on the bottom surface of the collection box 47, the plastic parts can be buffered to prevent damage.

[0059] As an embodiment of the present invention, Figure 7 As shown, the connecting pipe 45 is fixedly installed on the top of the outer surface of the telescopic portion 48 , and the top of the connecting pipe 45 is set as a bellows 14 .

[0060] During operation, when the connecting tube 45 is installed at a lower position, the plastic parts at the bottom of the collecting box 47 may block the connecting tube 45, and the exhaust fan 46 is unable to draw the closed cavity formed by the first lower template 42, the telescopic part 48 and the collecting box 47 into a negative pressure state. By fixing the connecting tube 45 on the top of the outer surface of the telescopic part 48, the plastic parts at the bottom of the collecting box 47 can be prevented from blocking the connecting tube 45, ensuring that the exhaust fan 46 draws the cavity into a negative pressure state. In addition, by setting the top of the connecting tube 45 as a bellows 14, it can cooperate with the telescopic part 48 to move up and down.

[0061] When the upper mold 41 is moved to fit together with the first lower mold plate 42, the second hydraulic rod 414 is stopped from moving downward, and the upper mold 41 is moved to fit together with the first lower mold plate 42 to form a closed mold. Then, plastic particles are fed into the injection mechanism 2 through the feed port 15, and the plastic is injected from the injection molding tube 3 through the injection mechanism 2 into the mold cavity formed by the upper mold 41 and the first lower mold plate 42. After the plastic part is formed, the second hydraulic rod 414 is driven to move upward, and the upper mold 41 fixedly connected to the second hydraulic rod 414 moves upward accordingly. Then, the motor 410 is connected to the external power supply and driven to rotate the motor 410, and the rotating shaft 411 fixedly connected to the motor 410 rotates accordingly. Similarly, the first lower mold plate 42 and the second lower mold plate 412 fixedly connected to the rotating shaft 411 rotate accordingly. When the template 42 rotates to the bottom, the first hydraulic rod 49 is driven to move up, and the clamping plate 44 fixedly connected to the first hydraulic rod 49 moves up accordingly. When the clamping plate 44 moves up to fit together with the first lower template 42, the first hydraulic rod 49 stops moving up. At this time, a closed cavity is formed between the first lower template 42, the telescopic part 48 and the collection box 47. Finally, the exhaust fan 46 is connected to the external power supply and driven to work. Since the exhaust fan 46 is connected to the closed cavity formed by the first lower template 42, the telescopic part 48 and the collection box 47 through the connecting pipe 45, the exhaust fan 46 can draw the cavity into a negative pressure state, thereby being able to suck the plastic parts on the first lower template 42 into the inside of the collection box 47, thereby removing the plastic parts on the first lower template 42, avoiding manual removal and reducing labor costs. In addition, while taking out the plastic parts, the second lower template 412 rotates to the top, and injection molding can be continued, which is conducive to continuous production.
