Description

Technical Field

[0001] The invention relates to the technical field of plastic parts processing, and more specifically to a rapid demoulding device for a plastic parts processing injection molding machine. Background Art

[0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, make it eject and fill the mold cavity, and then cool the mold to solidify the molten plastic to form a plastic part, completing the processing of the plastic part. Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling cooling - mold opening and part removal. After taking out the plastic part, the mold is closed again for the next cycle. However, because the plastic part is inside the mold, it is difficult to take out the plastic part manually, so a demoulding device is needed.

[0003] When the existing demoulding equipment is in use, the ejector rod is driven to move upward by a telescopic device such as a telescopic rod, thereby driving the plastic part in the mold to move upward, and then ejecting the plastic part in the mold, and then manually taking the mold out, so as to facilitate the workers to take out the plastic part. However, when the demoulding equipment is in use, the mold needs to be fully opened before the demoulding equipment is started to eject the plastic part, and the demoulding equipment needs to drive the ejector rod to move by the telescopic moving device to eject the plastic part, which makes the ejection speed of the plastic part slower, thereby reducing the working efficiency of the demoulding equipment.

[0042] See also Figures 1 to 12, a rapid demoulding device for a plastic parts processing injection molding machine, comprising a fixed seat 2, a lower mold 12 is fixedly connected to the upper surface of the fixed seat 2, an upper mold 10 is arranged above the lower mold 12, a No. 3 mounting groove 13 is opened on the upper surface of the fixed seat 2, a sliding mounting plate 15 is slidably connected inside the No. 3 mounting groove 13, and the upper surface of the sliding mounting plate 15 is fixedly connected to evenly distributed ejector rods 14, and the ejector rods 14 pass through the upper surface of the lower mold 12, an ejector assembly 5 is arranged between the upper mold 10 and the lower mold 12, and rectangular evenly distributed positioning rods 51 are fixedly connected to the lower surface of the upper mold 10;

[0043] The upper surface of the lower mold 12 is provided with rectangular positioning holes 52 evenly distributed, and the positioning rods 51 are slidably connected to the positioning holes 52, the inner wall of the No. 3 mounting groove 13 is provided with a No. 1 mounting groove 53 on both sides, and the positioning holes 52 pass through the No. 1 mounting groove 53, the interior of the No. 1 mounting groove is slidably connected to a No. 1 slider 54, and both ends of the sliding mounting plate 15 extend to the interior of the No. 1 mounting groove 53 and are fixedly connected to the No. 1 slider 54, and through holes 55 are provided at both ends of the upper surface of the No. 1 slider 54, and the positioning rods 51 pass through the through holes 55.

[0044] like Figure 1 As shown, the lower surface of the fixed seat 2 is fixedly connected to the bottom plate 1, the upper surface of the upper mold 10 is fixedly connected to the top plate 4, the center position of the upper surface of the upper mold 10 is fixedly connected to the injection port 11, and the injection port 11 passes through the upper surface of the top plate 4, and four rectangular and evenly distributed telescopic rods 3 are fixedly connected between the bottom plate 1 and the top plate 4.

[0045] like Figure 1 , Figure 2 As shown, a cooling cavity 16 is provided inside the upper mold 10 and the lower mold 12, and two connecting pipes are fixedly connected to one side of the inner wall of the cooling cavity 16, and the two connecting pipes are a water inlet pipe and a water outlet pipe respectively.

[0046] like Figure 2 , Figure 3 , Figure 4 As shown, there are two No. 1 sliders 54, and No. 2 mounting grooves 56 are provided inside the two No. 1 sliders 54, and two No. 2 sliders 57 are slidably connected inside the No. 2 mounting grooves 56, and grooves 511 are provided on the sides of the outer surfaces of the two No. 2 sliders 57 that are close to each other, and a No. 1 spring 59 is provided between the two opposite grooves 511, and a No. 1 clamping block 58 is fixedly connected on the sides of the outer surfaces of the two No. 2 sliders 57 that are close to each other, and the two No. 1 clamping blocks 58 are respectively penetrated in the through holes 55, and the lower side of the outer cylindrical surface of the positioning rod 51 is provided with a clamping groove 510 near the No. 1 clamping block 58.

[0047] When in use, the telescopic rod 3 is started to drive the top plate 4 to move downward, thereby driving the upper mold 10 to move downward, so that the upper mold 10 and the lower mold 12 are molded together, and then the molten plastic injection device is externally connected through the injection port 11 to inject the molten plastic into the mold, so that the molten plastic fills the cavity between the upper mold 10 and the lower mold 12, and then the coolant injection device is externally connected through the water inlet pipe to inject the coolant into the cooling cavity 16 to cool the molten plastic so that the molten plastic forms a plastic part and the processing of the plastic part is completed. The coolant can be returned to the coolant injection device through the water outlet pipe to facilitate the recycling of the coolant. At the same time, the coolant is made to flow in the cooling cavity 16, thereby improving the cooling effect of the coolant on the molten plastic. Then, the telescopic rod 3 is started again to drive the upper mold 10 to move upward, thereby opening the upper mold 10 and the lower mold 12, and then the sliding mounting plate 15 is driven to move upward by the external telescopic moving device, thereby driving the ejector rod 14 to move upward, and then the plastic part in the lower mold 12 is ejected to complete the demoulding of the plastic part.

[0048] However, the demoulding device needs to completely open the mold before the plastic part can be ejected from the lower mold 12, which reduces the working efficiency of the demoulding device. Therefore, an ejection assembly 5 is provided. When the mold is closed, the positioning rod 51 moves downward in the positioning hole 52 at the same time, so that the positioning rod 51 passes through the through hole 55. When the mold is opened, the positioning rod 51 is driven to move upward at the same time. When the slot 510 on the positioning rod 51 moves into the through hole 55, the two No. 2 sliders 57 are driven to move outward inside the No. 2 mounting slot 56 by the No. 1 spring 59, thereby driving the two No. 1 clamping blocks 58 to move outward, so that the two No. 1 clamping blocks 58 are respectively clamped into the two slots 510, thereby fixing the positioning rod 51 and the No. 1 slider 54, so that the positioning rod 51 drives the No. 1 slider 54 to move upward in the No. 1 mounting slot 53, thereby driving the sliding mounting plate 15 to move upward, and driving the ejection rod 14 to move upward, and then ejecting the plastic part in the lower mold 12, so that the demoulding device can drive the ejection rod 14 to move upward when the mold is opened, thereby ejecting the plastic part in the lower mold 12, thereby improving the demoulding speed of the demoulding device, thereby improving the working efficiency of the demoulding device.

[0049] like Figure 3 , Figure 5As shown, a stabilizing component 6 is arranged between the sliding mounting plate 15 and the lower surface of the No. 3 mounting groove 13, and the stabilizing component 6 includes a T-shaped clamping rod 64 fixedly connected to the lower end of the No. 3 mounting groove 13, and a No. 1 sliding groove 61 is commonly provided between the two No. 2 mounting grooves 56, and a No. 1 through-hole 63 penetrating through the lower surface of the sliding mounting plate 15 is provided at the lower end of the inner wall of the No. 1 sliding groove 61, and the T-shaped clamping rod 64 passes through the No. 1 through-hole 63, and one side of the outer surface of the two No. 2 sliding blocks 57 inside the No. 2 mounting groove 56 on one side is fixedly connected with a clamping plate 62, and one end of the two clamping plates 62 passes through the No. 1 sliding groove 61 and is fixedly connected to the two No. 2 sliding blocks 57 on the other side.

[0050] like Figure 4 , Figure 6 , Figure 7 As shown, the upper surfaces of the two No. 2 sliders 57 are provided with a releasing assembly 7, and the releasing assembly 7 includes trapezoidal grooves 71 respectively opened on the upper surfaces of the two No. 2 sliders 57, and the upper surface of the No. 1 slider 54 is provided with No. 2 openings 72 near the two trapezoidal grooves 71, and the two No. 2 openings 72 pass through the upper end of the inner wall of the No. 2 mounting groove 56, and the upper end of the inner wall of the No. 1 mounting groove 53 corresponding to the two No. 2 openings 72 are fixedly connected with trapezoidal blocks 73.

[0051] In the above embodiment, the ejection assembly 5 can drive the positioning rod 51 to move upward at the same time when the mold is opened, and then the positioning rod 51 and the No. 1 slider 54 are fixed by the engagement of the No. 1 clamping block 58 and the two clamping grooves 510, thereby driving the No. 1 slider 54 to move upward, thereby driving the sliding mounting plate 15 and the ejection rod 14 to move upward to eject the plastic part in the lower mold 12. However, when the positioning rod 51 and the No. 1 slider 54 are not fixed, because the positioning rod 51 is slidably connected to the through hole 55, and the No. 1 slider 54 is slidably connected to the No. 1 mounting groove 53, when the positioning rod 51 moves upward, the No. 1 slider 54 is easy to shake up and down in the No. 1 mounting groove 53, which reduces the stability of the ejection assembly 5. Therefore, a stabilizing assembly 6 is provided. When the positioning rod 51 and the No. 1 slider 54 are not fixed, the positioning rod 51 can be used to make the two No. 1 sliders 54 move upward. The No. 1 card block 58 moves toward the inside of the No. 2 mounting groove 56, and drives the two No. 2 sliders 57 to move toward the inside of the No. 2 mounting groove 56, thereby driving the two card plates 62 to move closer to each other in the No. 1 slide groove 61, so that the two card plates 62 are stuck under the T-shaped card rod 64, thereby fixing the sliding mounting plate 15 in the No. 3 mounting groove 13, which can effectively prevent the No. 1 slider 54 from shaking up and down in the No. 1 mounting groove 53, thereby improving the stability of the ejection assembly 5 when used, and when the positioning rod 51 and the No. 1 slider 54 are fixed, the two No. 2 sliders 57 move toward the outside of the No. 2 mounting groove 56, and at the same time drive the two card plates 62 to move away from each other in the No. 1 slide groove 61, so that the two card plates 62 are separated from the T-shaped card rod 64, and at the same time the T-shaped card rod 64 passes through the No. 1 opening 63, thereby releasing the fixing of the sliding mounting plate 15 and the No. 3 mounting groove 13.

[0052] In the above embodiment, the ejector assembly 5 can simultaneously drive the sliding mounting plate 15 and the ejector rod 14 to move upward when the mold is opened, so as to eject the plastic part in the lower mold 12. However, after the plastic part is ejected, the sliding mounting plate 15 and the ejector rod 14 cannot be reset in time because the positioning rod 51 and the first slider 54 are fixed, which affects the next use of the ejector assembly 5 and reduces the working efficiency of the demoulding device. Therefore, a release assembly 7 is provided. When the first slider 54 drives the sliding mounting plate 15 and the ejector rod 14 to move upward, when the first slider 54 moves to the upper end of the first mounting groove 53, the two trapezoidal blocks 73 respectively pass through the two second openings 72, so that the two trapezoidal blocks 73 are respectively inserted into the two trapezoidal grooves 71. The two trapezoidal blocks 73 are respectively inserted into the two trapezoidal grooves 71, and the two No. 2 sliders 57 can be driven to move closer to each other, so that the two No. 1 clamping blocks 58 are moved into the No. 2 mounting groove 56, thereby releasing the fixation of the positioning rod 51 and the No. 1 slider 54. Then, because the sliding mounting plate 15 slides in the No. 3 mounting groove 13, the sliding mounting plate 15 and the ejector rod 14 are driven to move downward in the No. 3 mounting groove 13 by their own weight, so that the sliding mounting plate 15 and the ejector rod 14 can be reset, which is convenient for the next use of the ejector assembly 5 and improves the working efficiency of the demoulding equipment.

[0053] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, there are four positioning holes 52 and four positioning rods 51, and a reset assembly 8 is arranged inside the positioning hole 52. The reset assembly 8 includes a No. 2 slide groove 81 respectively opened on the side of the inner circle surface of the four positioning holes 52 close to the No. 3 mounting groove 13, and a No. 1 rack 84 is slidably connected inside the four No. 2 slide grooves 81. A No. 4 slide groove 85 is opened on the lower surface of the lower mold 12 close to the four No. 2 slide grooves 81, and a connecting groove 87 is opened between the No. 2 slide groove 81 and the No. 4 slide groove 85. Gears 88 are rotatably connected inside the four connecting grooves 87, and the No. 1 rack 84 is meshed with the gear 88. A No. 1 slide rod 86 is slidably connected inside the four No. 4 slide grooves 85, and a No. 2 rack 89 is opened on the outer surface of the four No. 1 slide rods 86 close to the gear 88, and the No. 2 rack 89 is meshed with the gear 88.

[0054] like Fig.10 , Fig.11 As shown, a No. 3 slide groove 83 is opened on one side of the outer circular surface of the four positioning rods 51 close to the No. 2 slide groove 81, and a movable plate 82 is fixedly connected to the upper end of one side of the outer surface of the four No. 1 racks 84, and the four movable plates 82 pass through the No. 2 slide groove 81 and extend into the No. 3 slide groove 83.

[0055] In the above embodiment, by releasing the assembly 7, the fixing of the positioning rod 51 and the first slide block 54 can be promptly released after the plastic part in the lower mold 12 is ejected, so that the sliding mounting plate 15 and the ejection rod 14 can be reset. However, the sliding mounting plate 15 and the ejection rod 14 are driven by their own weight to move downward in the third mounting groove 13, so that the sliding mounting plate 15 and the ejection rod 14 are reset slowly, which further affects the next use of the ejection assembly 5 and reduces the working efficiency of the demoulding device. Therefore, a reset assembly 8 is provided. When the fixing of the positioning rod 51 and the first slide block 54 is released, the sliding mounting plate 15 and the ejection rod 14 are continuously reset. The positioning rod 51 is moved upward, thereby driving the moving plate 82 to move upward in the No. 2 slide groove 81 through the No. 3 slide groove 83, and driving the No. 1 rack 84 to move upward. Since the No. 1 rack 84 is meshed with the gear 88, the gear 88 can be driven to rotate in the connecting groove 87, and the gear 88 is meshed with the No. 2 rack 89, which can drive the No. 2 rack 89 to move downward, thereby driving the No. 1 slide bar 86 to move downward in the No. 4 slide groove 85, and then pushing the sliding mounting plate 15 to move downward, so that the sliding mounting plate 15 and the ejector rod 14 can be quickly reset, which is convenient for the next use of the ejector assembly 5, and improves the working efficiency of the demoulding equipment.

[0056] like Fig.10 , Fig.11 , Fig.12 As shown, a fixing component 9 is arranged above the No. 1 slider 54, and the fixing component 9 includes a connecting slot 91 opened between the two No. 4 slots 85 located above the No. 1 slider 54, and two No. 3 sliders 92 are slidably connected inside the two connecting slots 91, and a No. 2 spring 94 is arranged between the two No. 3 sliders 92, and a fixing block 93 is fixedly connected to the side of the outer surfaces of the two No. 3 sliders 92 away from each other, and the two fixing blocks 93 both penetrate into the two No. 4 slots 85.

[0057] like Fig.10 , Fig.12 As shown, the upper surfaces of the two No. 3 sliders 92 are each provided with a trapezoidal slide groove 95 that penetrates the No. 3 slider 92, the upper ends of the inner walls of the connecting slide grooves 91 are each provided with a No. 5 slide groove 96, and the lower ends of the No. 5 slide grooves 96 penetrate the lower ends of the inner walls of the connecting slide grooves 91, the two No. 5 slide grooves 96 are both slidably connected with No. 2 slide bars 97, and the two No. 2 slide bars 97 respectively penetrate the two trapezoidal slide grooves 95, the outer surfaces of the two No. 2 slide bars 97 are each provided with a trapezoidal slot 98 at the lower ends on one side that is close to each other, the upper and lower ends of the two No. 2 slide bars 97 are both fixedly connected with straight rods 99, and the straight rods 99 penetrate the upper and lower surfaces of the lower mold 12.

[0058] In the above embodiment, the sliding mounting plate 15 and the ejector rod 14 can be quickly reset by the reset component 8. However, after the sliding mounting plate 15 is reset, because the sliding mounting plate 15 is slidably connected to the No. 3 mounting groove 13, the sliding mounting plate 15 is easy to shake up and down, affecting the stability of the sliding mounting plate 15 and the ejector rod 14. Therefore, a fixing component 9 is provided. When the No. 1 slide bar 86 pushes the sliding mounting plate 15 downward to the lower end of the No. 3 mounting groove 13, the No. 2 spring 94 drives the two No. 3 sliders 92 to move away from each other in the connecting slide groove 91, thereby driving the two fixing blocks 93 to move away from each other, so that the two fixing blocks 93 are respectively inserted into the two No. 4 slide grooves 85, and the fixing block 93 is located above the No. 1 slide bar 86, thereby fixing the No. 1 slide bar 86, and then fixing the sliding mounting plate 15, which can effectively prevent sliding. The mounting plate 15 swings up and down, which improves the stability of the sliding mounting plate 15 and the ejector rod 14. Then, when the mold is closed, the upper mold 10 drives the two straight rods 99 on the upper side to move downward, thereby driving the two No. 2 slide bars 97 to move downward in the No. 5 slide groove 96, and the two No. 2 slide bars 97 respectively penetrate the two trapezoidal slide grooves 95, thereby driving the two No. 3 slide blocks 92 to move closer to each other, and then driving the two fixed blocks 93 to move into the connecting slide groove 91, so that the two fixed blocks 93 are fixed in the connecting slide groove 91, thereby releasing the fixation of the No. 1 slide bar 86. When the mold is opened, when the sliding mounting plate 15 moves to the lower surface of the lower mold 12, it will push the two straight rods 99 on the lower side to move upward, so that the trapezoidal slot 98 is engaged with the trapezoidal slot 95, thereby releasing the fixation of the two fixed blocks 93, which is convenient for the next use of the fixing component 9.

[0059] Instructions for use: Start the telescopic rod 3 to drive the top plate 4 to move downward, thereby driving the upper mold 10 to move downward, so that the upper mold 10 and the lower mold 12 are molded together, and at the same time, the straight rod 99 is pressed down to fix the fixing block 93 in the connecting slide groove 91, and at the same time, the stabilizing component 6 is started to fix the No. 1 slider 54 in the No. 1 mounting groove 53, and then the molten plastic injection device is connected to the injection port 11 to inject the molten plastic into the mold so that the molten plastic fills the cavity between the upper mold 10 and the lower mold 12, and then the coolant injection device is connected to the water inlet pipe to inject the coolant into the cooling cavity 16 to cool the molten plastic so that the molten plastic forms a plastic part, and the plastic part is completed. The mold is then opened, and the positioning rod 51 is driven to move upward, so that the No. 1 card block 58 is inserted into the card slot 510, the positioning rod 51 is fixed to the No. 1 slider 54, and the No. 1 slider 54 is released from the No. 1 mounting slot 53, thereby driving the sliding mounting plate 15 and the ejector rod 14 to move upward, and the plastic part in the lower mold 12 is ejected, and then the fixation between the sliding mounting plate 15 and the No. 1 slider 54 is released by the release component 7, and the straight rod 99 is pushed up at the same time to release the fixing block 93, and then the positioning rod 51 is continued to be moved upward, thereby starting the reset component 8 to push the sliding mounting plate 15 to move downward, and then the sliding mounting plate 15 is fixed by the fixing component 9.
