Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding equipment technology, and in particular to an injection transfer device for a plastic injection molding machine. Background Technology
[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment for making various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics, causing them to be injected and fill the mold cavity.
[0003] Chinese patent document CN222681576U discloses an injection transfer mechanism for an injection molding machine. This mechanism is installed between the injection stage and the machine frame and is used to adjust the position of the injection stage. The injection stage and the machine frame are slidably connected. The injection transfer mechanism includes a drive component and an injection transfer assembly. The injection transfer assembly includes a ball screw, a nut seat, a separator, a guide sleeve, and several bearings. An installation hole is provided on the injection stage, and the nut seat is arranged within the installation hole. The ball screw and the nut seat are threadedly connected. The bearing is sleeved on the leading end of the ball screw. The guide sleeve is arranged on the outside of the bearing and is located between the outer circumferential surface of the bearing and the inner wall of the installation hole. The separator is arranged between the nut seat and the guide sleeve and is mounted on the guide sleeve. Through the design of the guide sleeve and the separator, the nut seat and the bearing do not need to be installed separately from both sides; they can be installed and disassembled from only one side, greatly shortening the installation time and the disassembly time for later maintenance of the screw and bearing.
[0004] The existing technology has the following problems:
[0005] The way the lead screw is mounted on the ejector mechanism means that it needs to be removed from the transmission components during maintenance. This increases the complexity of installation and disassembly, and increases maintenance costs. In addition, the lead screw and bearing sleeve are connected together, making it difficult to maintain them separately. Utility Model Content
[0006] This invention provides an injection transfer device for a plastic injection molding machine to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0008] A plastic injection molding machine injection device includes a mechanism platform, a rotating mechanism is movably mounted on the right side of the mechanism platform near the front side, a mounting bracket is fixedly connected to the right side of the mechanism platform near the upper and lower sides, a fixing mechanism is fixedly sleeved on the inner side of the mechanism platform, an injection mechanism is movably mounted on the left side of the fixing mechanism, and a stabilizing mechanism is fixedly connected to the front and rear sides of the injection mechanism.
[0009] The fixing mechanism includes a mechanism sleeve, the outer side of which is fixedly sleeved onto the inner side of the mechanism platform. A bearing is fixedly sleeved onto the inner side of the mechanism sleeve. A limit seat is movably mounted on the inner side of the bearing. A connecting plate is movably sleeved onto the inner side of the limit seat. A lead screw is fixedly connected to the left side of the connecting plate. A threaded sleeve is threadedly connected to the outer side of the lead screw. A first telescopic rod is fixedly connected to the inner right side of the mounting frame. A rotating seat is rotatably connected to the left side of the first telescopic rod.
[0010] Preferably, a frustum is fixedly connected to the outer side of the lead screw near the right side, and a stabilizing seat is fixedly connected to the left side of the limiting seat, with the outer side of the frustum movably sleeved on the inner side of the stabilizing seat.
[0011] Preferably, a rubber pad is fixedly connected to the outer side of the frustum.
[0012] Preferably, the stabilizing mechanism includes a slide table, the sides of which are movably mounted on the front and rear sides of the injection mechanism. A locking platform is movably sleeved on the outer side of the slide table. A movable plate is fixedly connected to the side of the locking platform away from the injection mechanism. Several inclined grooves distributed front and back are opened on the upper and lower sides of the movable plate. Two adjusting plates distributed upper and lower are overlapped on the upper and lower sides of the movable plate. A second telescopic rod is fixedly connected to the side of the two adjusting plates that are far apart from each other. Several guide shafts distributed front and back are rotatably connected to the side of the two adjusting plates that are close to each other. The outer side of the guide shaft is slidably connected to the inner side of the inclined groove.
[0013] Preferably, the outer side of the slide table and the inner side of the card table are both isosceles trapezoids, and the inner side of the card table is rotatably connected to several needle rollers distributed in the front and back.
[0014] Preferably, the outer sides of the moving plate, the guide shaft, and the adjusting plate are all provided with a wear-resistant layer.
[0015] Preferably, a plurality of limiting rods distributed front to back are fixedly connected to the side of the movable plate away from the injection mechanism.

A fixed plate is movably sleeved on the outer side of the limiting rods near the right side. A spring is movably sleeved on the outer side of the plurality of limiting rods, and the spring is positioned between the fixed plate and the limiting plate.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. This utility model uses a fixing mechanism, specifically by directly inserting a pin between the rotating seat and the connecting plate. Then, the first telescopic rod drives the rotating seat to move and tightly press the frustum against the inner side of the stabilizing seat, thus fixing the lead screw. This makes installation and disassembly convenient and facilitates later maintenance. At the same time, the bearing and the lead screw are separated from each other, so they will not interfere with each other during maintenance.
[0018] 2. This utility model sets up a stabilizing mechanism, specifically by using a second telescopic rod to drive the mounting plate and the slide plate to fit tightly together, so that the injection mechanism can be quickly installed and disassembled on the stabilizing component. At the same time, it avoids the problem of large wear between components caused by directly using a connecting frame, which leads to overall instability in operation. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figures 1-5 As shown, a plastic injection molding machine injection device includes a mechanism platform 1. A rotating mechanism 2 is movably installed on the right side of the mechanism platform 1 near the front side. A mounting bracket 3 is fixedly connected to the right side of the mechanism platform 1 near the upper and lower sides. A fixing mechanism 4 is fixedly sleeved on the inner side of the mechanism platform 1. An injection mechanism 5 is movably installed on the left side of the fixing mechanism 4. A stabilizing mechanism 6 is fixedly connected to the front and rear sides of the injection mechanism 5.
[0027] The fixing mechanism 4 includes a mechanism sleeve 41. The outer side of the mechanism sleeve 41 is fixedly sleeved on the inner side of the mechanism platform 1. A bearing 42 is fixedly sleeved on the inner side of the mechanism sleeve 41. A limit seat 43 is movably installed on the inner side of the bearing 42. A connecting plate 49 is movably sleeved on the inner side of the limit seat 43. A lead screw 410 is fixedly connected to the left side of the connecting plate 49. A threaded sleeve 46 is threadedly connected to the outer side of the lead screw 410. A first telescopic rod 44 is fixedly connected to the inner right side of the mounting bracket 3. A rotating seat 45 is rotatably connected to the left side of the first telescopic rod 44.
[0028] It should be noted that the injection mechanism 5 has the same structural design as the component with the same function in the reference case. The rotating mechanism 2 is used to drive the rotating seat 45 to rotate. During installation, the connecting plate 49 is directly inserted into the inner side of the limiting seat 43. The limiting seat 43 is fixed in the bearing 42. It is difficult to disassemble and assemble the two directly by plugging and unplugging. However, the connecting plate 49 can be quickly removed and put into the limiting seat 43 by plugging and unplugging. Then, the connecting plate 49 and the rotating seat 45 are fixed with a pin. This pin is fixed with a spring clip or threaded nail to prevent the pin from coming out of the rotating seat 45. The first telescopic rod 44 is a hydraulic rod. By driving the rotating seat 45 to move to the right, the connecting plate 49 is tightened, so that the lead screw 410 is quickly fixed. During maintenance, there is no need to operate the rotating seat 45, which reduces the maintenance difficulty.
[0029] like Figure 3 As shown, a frustum 47 is fixedly connected to the outer side of the lead screw 410 near the right side, and a stabilizing seat 48 is fixedly connected to the left side of the limiting seat 43. The outer side of the frustum 47 is movably sleeved on the inner side of the stabilizing seat 48.
[0030] It should be noted that the shape of the frustum 47 is such that after the frustum 47 is inserted into the inside of the stabilizer 48, the stabilizer 48 stabilizes the position of the frustum 47, thus preventing the lead screw 410 from deflecting due to gaps between components.
[0031] like Figure 3 As shown, a rubber pad is fixedly connected to the outer side of the frustum 47.
[0032] It should be noted that the rubber pad is used to avoid rigid contact between the frustum 47 and the stabilizer 48, which would cause excessive compression between the components when the first telescopic rod 44 pulls the connecting plate 49, resulting in component deformation. The rubber pad is located on the outer bottom of the frustum 47. When the outer part of the frustum 47 near the upper side is tightly fitted with the stabilizer 48, the rubber pad is in a compressed state, which avoids the rubber pad from completely covering the frustum 47 and causing the lead screw 410 to be unstable due to its own compressibility.
[0033] like Figure 4 , Figure 5As shown, the stabilizing mechanism 6 includes a slide table 61. The sides of the slide table 61 are movably mounted on the front and rear sides of the injection mechanism 5. A locking table 62 is movably sleeved on the outer side of the slide table 61. A movable plate 63 is fixedly connected to the side of the locking table 62 away from the injection mechanism 5. Several inclined grooves 64 distributed front and back are opened on the upper and lower sides of the movable plate 63. Two adjusting plates 66 distributed upper and lower overlap on the upper and lower sides of the movable plate 63. A second telescopic rod 67 is fixedly connected to the side of the two adjusting plates 66 that is far away from each other. The movable end of the second telescopic rod 67 is fixed on the adjusting plate 66, while the fixed end is installed on the support frame around the equipment. The support frame is used to support the stabilizing mechanism 6 as a whole. This is a prior art. As in the reference case, the connecting frame is installed in the whole structure. Several guide shafts 68 distributed front and back are rotatably connected to the side of the two adjusting plates 66 that is close to each other. The outer side of the guide shaft 68 is slidably connected to the inner side of the inclined groove 64.
[0034] It should be noted that the second telescopic rod 67 is a hydraulic rod. The second telescopic rod 67 drives the adjusting plate 66 to move, so that the guide shaft 68 slides in the inclined groove 64, thereby pushing the clamping table 62 towards the slide table 61, so that the slide table 61 is quickly installed on the clamping table 62.
[0035] like Figure 5 As shown, the outer side of the slide table 61 and the inner side of the mounting plate 62 are both isosceles trapezoids, and several needle rollers distributed in the front and back are rotatably connected to the upper and lower sides of the inner side of the mounting plate 62.
[0036] It should be noted that the shapes of the slide table 61 and the locking table 62 stabilize the slide table 61, and the needle roller is used to reduce the wear on the slide table 61. Even if the slide table 61 is worn, it can be stabilized again by relying on the second telescopic rod 67.
[0037] like Figure 5 As shown, wear-resistant layers are provided on the outer sides of the movable plate 63, the guide shaft 68, and the adjusting plate 66.
[0038] It should be noted that the wear-resistant layer is used to improve the wear resistance of the components, and the relative movement between the components only occurs when the slide 61 is installed on the clamping table 62 or during disassembly.
[0039] like Figure 5 As shown, a number of limiting rods 65 distributed front to back are fixedly connected to the side of the movable plate 63 away from the injection mechanism 5. A limiting plate 610 is fixedly connected to the outer side of the limiting rods 65 near the left side. A fixed plate 69 is movably sleeved on the outer side of the limiting rods 65 near the right side. A spring 611 is movably sleeved on the outer side of the limiting rods 65, and the spring 611 is positioned between the fixed plate 69 and the limiting plate 610.
[0040] It should be noted that the spring 611 is a tension spring. By pulling the fixed plate 69, when the adjusting plate 66 is reset, the spring 611 pulls the locking plate 62, causing the locking plate 62 to move away from the outside of the slide table 61.
[0041] The working principle of this utility model is as follows: First, during installation, the connecting plate 49 is directly inserted into the inner side of the limiting seat 43. Then, a pin is used to fix the connecting plate 49 and the rotating seat 45. The first telescopic rod 44 is a hydraulic rod that drives the rotating seat 45 to move to the right, tightening the connecting plate 49, so that the lead screw 410 is quickly fixed. During maintenance, there is no need to operate the rotating seat 45, reducing the maintenance difficulty. The shape of the truncated cone 47 ensures that after the truncated cone 47 is inserted into the inner side of the stabilizing seat 48, the stabilizing seat 48 stabilizes the position of the truncated cone 47, preventing the lead screw 410 from deflecting due to gaps between components. By directly inserting a pin between the rotating seat 45 and the connecting plate 49, and then the first telescopic rod 44 drives the rotating seat 45 to move, pressing the truncated cone 47 tightly against the inner side of the stabilizing seat 48, the lead screw 410 is fixed. Installation is convenient, disassembly is convenient, and later maintenance is easy. At the same time, the bearing 42 is separated from the lead screw 410, and during maintenance, both are easily separated. Without mutual interference, the second telescopic rod 67 is a hydraulic rod. The second telescopic rod 67 drives the adjusting plate 66 to move, causing the guide shaft 68 to slide in the inclined groove 64, thereby pushing the clamping platform 62 towards the slide table 61, so that the slide table 61 is quickly installed on the clamping platform 62. The shape of the slide table 61 and the clamping platform 62 makes the slide table 61 stable. The needle roller is used to reduce the wear on the slide table 61. Even if the slide table 61 is worn, it can be stabilized again by relying on the second telescopic rod 67. The spring 611 is a tension spring. By pulling the fixing plate 69, when the adjusting plate 66 is reset, the spring 611 drives the clamping platform 62, so that the clamping platform 62 moves away from the outside of the slide table 61. The second telescopic rod 67 drives the clamping platform 62 to be tightly attached to the slide table 61, so that the injection mechanism 5 can be quickly installed and disassembled on the stabilizing component. At the same time, it avoids the problem of large wear between components caused by directly using the connecting frame, which leads to the instability of the overall operation.
[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
