[0035] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0036] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0039] In one embodiment of this utility model, according to Figure 1-6 As shown, the system includes a support 100; an operating platform 110 is mounted on the support 100, and a slidable lower template 120 is mounted on the operating platform 110; a mold is mounted on the lower template 120; a driving device is also mounted on the lower template 120, which can drive the lower template 120 to slide linearly on the operating platform 110. A first injection molding device 200 and a second injection molding device 300 are mounted on the upper part of the operating platform 110. The first injection molding device 200 includes a first mold clamping device 210 and a first injection device 220; the first injection device 220 is mounted on the first mold clamping device 210. The second injection molding device 300 includes a second mold clamping device 310 and a second injection device; the second injection device is mounted on the second mold clamping device 310.

[0040] Specifically, by setting the first mold clamping device 210 and the second mold clamping device 310 on the operating platform 110, the height of the operating platform 110 can be reduced, making it easier for users to install molds. By setting the first injection molding device 200 and the second injection molding device 300, plastics of different colors or materials can be injected into the same mold to produce composite products, meeting the diverse injection molding processing needs of users.

[0041] It is understandable that when the mold is placed on the lower mold plate 120, and the user wants to make a two-color or two-material composite product, the first injection molding device 200 and the second injection molding device 300 perform injection molding in sequence to obtain a two-color or two-material composite product. Specifically, when the lower mold plate 120 is located at the position of the first injection molding device 200, the first mold closing device 210 closes the mold, the first injection device 220 performs injection molding, the mold opens, the driving device moves the lower mold plate 120 to the position of the second injection molding device 300, the second mold closing device 310 closes the mold, the second injection device performs injection molding, the mold opens, and the composite product is obtained.

[0042] like Figure 5 As shown, the lower template 120 is provided with multiple placement holes 122, and a universal ball 700 is provided in each placement hole 122. The universal ball 700 includes a housing 710. The housing 710 has a mounting cavity 720 with one end connected to the outside. The mounting cavity 720 has a base 730. The base 730 has a sliding groove 731. Multiple small balls 732 are placed on the sliding groove 731. A ball head 740 is placed on the multiple small balls 732. The mounting cavity 720 is covered with an end cap 750. The end cap 750 has a leakage hole. The ball head 740 is kept at least partially protruding from the leakage hole 751, so that the ball head 740 can rotate relative to the housing 710 under the action of external force for transporting the mold, making it easy to align the mold when changing the mold.

[0043] according to Figure 2-4As shown, as a preferred embodiment, the following structure of the drive device is selected, including two parallel racks 130 and a drive assembly 140 meshing with the two racks 130. The drive assembly 140 is connected to the lower template 120. The drive assembly 140 includes a motor 141. The motor 141 is connected to a reducer 142, and the reducer 142 is connected to a drive gear 143. A driven gear 144 is meshed with the drive gear 143. The drive gear 143 and the driven gear 144 are located between the two racks 130 and are respectively meshed with one of the racks 130. The motor 141 drives the drive gear 143 to rotate, thereby causing the lower template 120 to slide linearly on the operating platform 110.

[0044] Specifically, the reducer 142 is fixedly connected to the lower template 120. The motor 141 can be a servo motor 141. The motor 141 rotates and the speed is reduced by the reducer 142, which increases the torque to drive the drive gear 143 to rotate. The driven gear 144 follows the drive gear 143 to rotate. The drive gear 143 and the driven gear 144 are located between the two racks 130 and are respectively meshed with one of the racks 130, so that when the drive gear 143 rotates, it can move along the direction of the rack 130, thereby driving the lower template 120 to move on the operating platform 110.

[0045] It is understood that the drive unit may also include a cylinder 610 drive, a servo motor 141 with a lead screw module, and an electric push rod. The option of using a motor 141 with gears is preferred, as it offers high speed, a movement method with gear and rack 130 meshing, long service life, and stable movement.

[0046] according to Figure 1-3 As shown, the first mold closing device 210 includes a plurality of first mold closing pillars 211 and a first upper template 212 through which the plurality of first mold closing pillars 211 pass; one end of each first mold closing pillar 211 is connected to the operating platform 110 and the other end is connected to the first mold locking device, the first mold locking device acts on the first upper template 212, and the operating platform 110 is provided with a first lifting device, the first lifting device acts on the first upper template 212.

[0047] Specifically, there are four first mold clamping pillars 211, which are respectively installed at the four corners of the first upper mold plate 212 for greater stability. The first mold clamping device is located on the operating platform 110. In traditional vertical injection molding machines, the first mold clamping device is generally located at the bottom of the operating platform 110, which is large in size and occupies bottom space. It can only increase the height of the operating platform 110, which means that when changing molds, people generally need to use ladders to climb up for work, which is very inconvenient.

[0048] according to Figure 1-3As shown, the first mold-locking device includes two first mold-locking cylinders 213; the two first mold-locking cylinders 213 are respectively disposed on both sides of the first upper mold plate 212, each first mold-locking cylinder 213 is fixedly connected to the first mold-closing column 211, and the output shaft of each first mold-locking cylinder 213 acts on the first upper mold plate 212 and provides a mold-locking force to ensure that the mold will not open under the impact of the injection molding process. The first lifting device includes two first rapid mold-moving cylinders 214; the two first rapid mold-moving cylinders 214 are disposed on both sides of the first upper mold plate 212 corresponding to the two first mold-locking cylinders 213, and the two first rapid mold-moving cylinders 214 are fixedly disposed on the operating platform 110, and the output shaft of the first rapid mold-moving cylinders 214 acts on the first upper mold plate 212 and drives the first upper mold plate 212 to move up and down to realize mold closing and mold opening.

[0049] Specifically, two first mold-locking cylinders 213 are respectively located on both sides of the upper part of the first upper mold plate 212. Each first mold-locking cylinder 213 has a first mold-closing column 211 on both sides. The first mold-locking cylinder 213 fixes itself to the two adjacent first mold-closing columns 211 through a connecting device. Its output shaft is connected to the first upper mold plate 212 and acts on it to provide mold-locking force, ensuring that the mold will not be opened under the impact of the injection process. The greater the mold-locking force, the larger the first mold-locking cylinder 213. It is located at the bottom of the operating platform 110, has a large volume, occupies the bottom space, and can only increase the height of the operating platform 110.

[0050] Two first rapid mold moving cylinders 214 are respectively located on both sides of the bottom of the first upper mold plate 212. The first rapid mold moving cylinders 214 are arranged opposite to the first mold locking cylinder 213. Their main function is to provide high-speed, low-pressure motion during mold closing and mold opening, so as to improve production efficiency and reduce cycle time.

[0051] Two first mold-locking cylinders 213 and two first quick-moving mold-shifting cylinders 214 are respectively set on both sides of the first upper mold plate 212, making its structure more stable. The two first mold-locking cylinders 213 are changed from being set at the bottom to being set at the top, which changes the center of gravity and requires higher stability.

[0052] The first injection unit 220 includes an injection stage, a barrel, and a nozzle. The barrel is mounted on the injection stage, and the nozzle communicates with the barrel. A screw is installed inside the barrel, and the screw is connected to an injection cylinder. The injection cylinder is used to hydraulically push the screw forward, injecting the molten plastic inside the barrel into the mold cavity at high pressure and high speed. The injection stage is used to move the position of the nozzle to ensure that the nozzle fits snugly against the mold for injection. The injection stage includes two cylinders. It is understood that the first injection unit 220 is mature existing technology, and will not be described in detail here.

[0053] The second mold clamping device 310 includes a plurality of second mold clamping pillars 311 and a second upper mold plate 312 through which the plurality of second mold clamping pillars 311 pass. Each second mold clamping pillar 311 is connected at one end to an operating platform 110 and at the other end to a second mold clamping device. The second mold clamping device acts on the second upper mold plate 312. The operating platform 110 is provided with a second lifting device, which acts on the second upper mold plate 312. The second mold clamping device includes two second mold clamping cylinders 313. The two second mold clamping cylinders 313 are respectively located on both sides of the second upper mold plate 312. Each second mold clamping cylinder 313 is fixedly connected to the second mold clamping pillar 311. The output shaft of each second mold clamping cylinder 313 acts on the second upper mold plate 312 and provides a clamping force to ensure that the mold will not open under the impact of the injection molding process. The second lifting device includes two second rapid mold moving cylinders 314; the two second rapid mold moving cylinders 314 are corresponding to two second mold locking cylinders 313 and are arranged on both sides of the second upper mold plate 312. The two second rapid mold moving cylinders 314 are fixedly arranged on the operating platform 110, and the output shaft of the second rapid mold moving cylinders 314 acts on the second upper mold plate 312 and drives the second upper mold plate 312 to move up and down to realize mold closing and mold opening.

[0054] It is understood that the second injection molding device 300 and the first injection molding device 200 have the same structure, except that they can be filled with plastics of different colors or materials. This will not be repeated here.

[0055] like Figure 3 and 4 As shown, the operating platform 110 has guide strips 320 and second injection devices 400 on both sides. Each guide strip 320 and second injection device 400 has a guide edge 410 at its top. The lower template 120 has guide grooves 121 on both sides. The bottom of the guide grooves 121 slides in contact with the bottom of the guide edge 410, serving as a motion guide. Specifically, the two guide strips 320 and second injection devices 400 mainly serve a guiding function. To facilitate sliding, pulleys are also provided on both sides of the lower template 120 to assist sliding. The pulleys slide on the guide strips 320 and second injection devices 400. It can be understood that there is a pad under the lower template 120, and the lower template 120 slides on the pad and the rack 130, rather than being suspended in the air.

[0056] like Figure 3 As shown, the operating platform 110 is equipped with multiple proximity switches 500, which are used to detect the position of the lower template 120.

[0057] like Figure 6As shown, the bottom of the lower template 120 is also provided with an ejector pin assembly 600, which can assist in ejecting the molded workpiece from the mold. Specifically, compared with manual removal, it increases production efficiency. The ejector pin assembly 600 includes a cylinder 610 and an ejector 620. The ejector 620 includes a baffle 621. The output shaft of the cylinder 610 passes through a base plate 630 and acts directly on the baffle 621. The baffle 621 is provided with a number of ejector pins 622. The baffle 621 is also provided with two guide rods 623, which are connected to the base plate 630. The output shaft of the cylinder 610 extends and retracts, driving the baffle 621 to move, further driving the number of ejector pins 622 to pass through the lower template 120 and the mold to eject the molded workpiece.

[0058] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
