Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molding equipment, in particular to a double-station integrated injection molding equipment. Background Art
[0002] The working principle of an injection molding machine is to inject plasticized, molten (i.e., viscous and fluid) plastic into a closed mold cavity using the thrust of a screw (or plunger). After solidification and finalization, the finished product is obtained. Injection molding is a cyclic process, with each cycle consisting of: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and part removal. After the part is removed, the mold is closed again, and the next cycle begins.
[0003] Existing injection molding machines primarily utilize a single-station design. The one-shot molding process is no longer sufficient to meet the current demand for product diversity, especially when adding accessories or parts to a continuous injection molding process. Especially when accessories have multiple specifications or styles to meet the production of different series of the same product, a single-station process requires a large number of molds that are roughly similar but with minor differences, directly resulting in extremely high production costs. If two processes have subtle differences and cannot be processed simultaneously using the same mold, the two production processes must be performed independently, requiring two injection molding machines to achieve this, which is costly and space-consuming. Utility Model Content
[0004] In response to the increasingly diversified demands for current products, the single workstation of injection molding equipment cannot meet the low-cost production problem of continuous processes. The utility model provides a double-station integrated injection molding equipment, which switches the workstations through a rotary table, so that the injection molding of two consecutive processes can be completed in one mold closing, greatly improving production efficiency.
[0005] To achieve the above-mentioned purpose, the present invention selects the following technical solutions: a dual-station integrated injection molding equipment, including an equipment body, an injection mechanism, a workbench and a manipulator, the workbench including a rotating table located below and a fixed table located above, the rotating table is provided with a first station and a second station that are continuous and have different processes, the injection mechanism is provided with a first nozzle and a second nozzle, the first nozzle and the second nozzle are arranged above the fixed table and pass through the fixed table during working movement to respectively cooperate with the first mold on the first station and the second mold on the second station for injection molding, the manipulator is fixed to the fixed table through a fixed base, the manipulator includes at least one joint manipulator arm and a fine-tuning rotating mechanism and a suction mechanism on the fine-tuning rotating mechanism, the manipulator is located at the second station and is adjusted by the joint manipulator arm to extend the suction mechanism into the second mold during working movement.

[0007] As a further improvement of the present invention: the suction mechanism includes a suction cylinder, a translation frame and a plurality of suction cups. The translation frame is suspended under the rotating frame and can be arranged to be translated and adjusted. The plurality of suction cups are arranged on the translation frame to suck the parts required for the second workstation and place them into the second mold.

[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] The utility model uses a rotary table to switch workstations, allowing injection molding of two consecutive processes to be completed in a single mold closing, greatly improving production efficiency. At the same time, when two consecutive processes with only slight differences are required, the need for an additional injection molding line is avoided. The previous and next processes can be produced simultaneously in a single mold closing of the same integrated injection molding equipment, greatly reducing production costs. The rotary table is used to effectively switch between two workstations to meet the diversity of production products. In the case of the same process, dual workstations can also be configured with dual molds to achieve double production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] One embodiment of the present invention provides a dual-station integrated injection molding machine, which is primarily designed for continuous processes on the same product or injection molded workpiece, and can achieve dual-station switching by rotating the worktable. In particular, when the workpieces of the two processes have the same appearance and the latter process only adds accessories or parts compared to the former process, a robot positioned at the second station automatically adds the corresponding accessories or parts to the latter process and the product, thereby improving production efficiency. In particular, when the accessories or parts added to the latter process have multiple styles or specifications, it is possible to avoid redesigning molds or producing supporting equipment for the corresponding products or processes. This embodiment can achieve the production of different series of styles for the same product by simply using the robot at the second station to absorb the accessories or parts and add them to the process. Furthermore, when it is necessary to insert related accessories in a secondary injection molding process so that the accessories are wrapped or embedded in the injection molded workpiece, this embodiment completes the primary injection molding process at the first station, then rotates the worktable to switch to the second station, and the robot adds the accessories to complete the secondary injection molding process. This allows the two injection molding processes of the two processes to be performed simultaneously on one machine, thereby improving production efficiency.
[0022] A dual-station integrated injection molding device in this embodiment, such as Figure 1-4 As shown, the device includes a main body 100, a glue injection mechanism 200, a workbench 300 and a manipulator 400. The workbench 300 includes a rotating table 310 located below and a fixed table 320 located above. The rotating table 320 is provided with a first workstation 510 and a second workstation 520 that are consecutive and have different processes. The glue injection mechanism 200 is provided with a first nozzle 210 and a second nozzle 220. The first nozzle 210 and the second nozzle 220 are arranged above the fixed table 320 and pass through the fixed table 320 during working movement. The first mold 610 on the first station 510 and the second mold 620 on the second station 520 cooperate for injection molding. The manipulator 400 is fixed to the fixed platform 320 through a fixed base 410. The manipulator 400 includes at least one joint robot arm 420 and a fine-tuning rotation mechanism 430 and a suction mechanism 440 on the fine-tuning rotation mechanism 430. The manipulator 400 is located at the second station 520 and is adjusted by the joint robot arm 420 to extend the suction mechanism 440 into the second mold 620 during working movement.
[0023] It should be noted that this embodiment does not impose any restrictions on the power structure, action and principle of the injection molding equipment used for mold closing and injection molding. Technical personnel can set them according to actual usage requirements. This embodiment uses existing technologies for other structures of the injection molding equipment, such as the movement of the workbench to enable the injection mold to close and open, the injection mechanism to perform injection molding after closing the mold, etc., as long as it can be used for conventional production and can realize its own structural functions.
[0024] Furthermore, the fine-tuning rotation mechanism 430 includes a rotating joint seat 431 and a rotating frame 432 . One end of the rotating joint seat 431 is connected to the joint robot arm 420 , and the other end is connected to the rotating frame 432 . The suction mechanism 440 is disposed on the rotating frame 432 .
[0025] In this embodiment, the fixed base 410 of the manipulator 400 is fixed on one side of the fixed platform 320 and aligned with the process center position of the second workstation 520. Then, the three-joint manipulator arm 420 is connected between the fixed base 410 and the fine-tuning rotation mechanism 430, so that the fine-tuning rotation mechanism 430 and the suction mechanism 440 have sufficient stroke to extend into the second mold, and the rotation adjustment is performed through the rotating joint seat 431 to correct the angle of the accessories or parts added to the relevant process.
[0026] Furthermore, the suction mechanism 440 includes a suction cylinder 441, a translation frame 442 and a plurality of suction cups 443. The translation frame 442 is suspended under the rotating frame 432 and can be adjusted translationally. The plurality of suction cups 443 are arranged on the translation frame 442 to suck the parts required for the second workstation and place them into the second mold. The suction cylinder 441 is arranged on the rotating frame 432 and is respectively connected to the plurality of suction cups 443.
[0027] In this embodiment, the translation frame 442 can be translated and adjusted below the rotating frame 432 to move the aligned process accessories in the left-right direction. Those skilled in the art will appreciate that the fine-tuning rotation mechanism and the translation frame can be locked with fasteners after rotation, and the suction pipes connecting the suction cylinder to the plurality of suction cups are not shown in the figure. However, these locking operations and the connection of the suction pipes are conventional methods in the art and will not be detailed in this embodiment.
[0028] Furthermore, the rotating platform 310 includes a rotating disk 311 with a rotational power and a first fixed plate 312 mounted on the rotating disk 311. The lower mold plates of the first mold 610 and the second mold 620 are fixed to the first fixed plate 312 and are symmetrically arranged about the rotation axis of the rotating disk 311. It should be noted that the rotation of the rotating disk and the mechanism for providing the rotational power are achieved using conventional technical means and will not be described in detail in this embodiment.
[0029] Furthermore, the fixing platform 320 is provided with positioning rings and winding sleeves corresponding to the first nozzle 210 and the second nozzle 220, respectively, and a second fixing plate 321. The winding positions of the first mold 610 and the second mold 620 are aligned with the winding sleeves, and the upper mold plates of each are fixed to the second fixing plate 321. It should be noted that the positioning rings and winding sleeves are conventional means in the field of injection molding machines to achieve precise alignment of the nozzles with the mold windings and to achieve glue injection, and this embodiment will not be described in detail.
[0030] In this embodiment, the first and second molds are identical, and the workstations are switched by rotating the turntable 180°. This embodiment uses a square and symmetrical product as an example. If the molds are asymmetrical, the molds in one of the workstations can be reversed. The lower mold plate and movable mold portion of the first mold are swapped with the lower mold plate and movable mold portion of the second mold via rotation, with the lower mold plate and movable mold portion of the first mold being transferred to the second workstation. That is, after a single mold-closing injection molding cycle, the second mold in the second workstation removes the molded product after mold opening. The turntable then rotates, transferring the movable mold portion of the first mold and the product to the second workstation. The movable mold portion and the fixed mold portion of the second mold are then combined for production. Prior to mold closing, a robotic arm is activated to grab the corresponding process component, place it in a pre-designated process position, and then eject it. This means that the component is placed in the pre-designated position on the product formed in the first workstation, allowing for subsequent production. Simultaneously, during this mold closing cycle, the first workstation also performs the preceding process, significantly improving production efficiency. Furthermore, in some embodiments, a robot may not be provided, and double production efficiency can be achieved in one-time mold closing and injection molding by configuring dual molds at dual stations.
[0031] In order to better understand the structure of the injection molding equipment, in an optional embodiment, for the secondary injection molding process, it is necessary to fix the parts on the primary injection molded part after the primary injection molding, and perform secondary injection molding, so that the injection molded product uses different injection molding compounds to fix the parts or products as an accessory and is accurately positioned and embedded in the upper and lower layers of plastics of different colors. For this type of secondary injection molded product, in this embodiment, the cavity heights of the first mold and the second mold after mold closing are different (this setting can be achieved by simply changing the height of the fixed mold on the first station and keeping the movable molds on the two stations consistent). First, injection molding is performed at the first station to form a first pre-injection molded part with a thinner film. Then, the two stations are switched by rotating the turntable so that the movable mold of the first mold is aligned with the fixed mold of the second mold. At this time, the corresponding accessories are sucked into the designated position by the robot. The designated position is pre-set relative to the process center by fine-tuning the rotation mechanism and the translation frame. After the corresponding accessories are placed on the first pre-injection molded part, the robot is controlled to exit. Then, mold closing is performed so that the movable mold of the second mold cooperates with the first mold for injection molding. After the mold is opened, the product is demolded and taken out. At the same time, the first pre-injection molded part of the first station is also produced synchronously. After switching the stations, the next production process can be carried out, which greatly improves production efficiency.
[0032] The above disclosure is only one or more preferred embodiments of the present invention, which is used to help understand the utility model concept of the technical solution, and does not limit the present invention in other forms. Technical personnel in the relevant field may make other equivalent or customary replacement solutions based on the features defined by the present invention, which still fall within the scope covered by the present invention.
