Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically a vertical injection molding machine with a turret mechanism. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

[0003] In existing vertical injection molding machines, after injection molding is completed, the mold is opened and the plastic part is ejected by ejector pins. The plastic part is then removed manually or by a robot. If the plastic part requires auxiliary tools for molding, manual assistance or a robot is needed to complete the process. This results in high labor costs, a simple structure, and the inability to automatically demold the plastic part after it has been molded with auxiliary tools to continue production. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a turret mechanism vertical injection molding machine to solve the problems mentioned in the background. This utility model has a novel structure. When plastic parts require auxiliary tools for molding in a vertical injection molding machine, it can automatically complete plastic injection and demolding, automating production, improving production efficiency, and facilitating quick replacement of auxiliary tools for plastic parts.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A vertical injection molding machine with a turret mechanism, including a machine housing, a turret mechanism mounted on the top surface of the machine housing, the turret mechanism including a core support plate, two sets of plastic part auxiliary tools mounted on the four sides of the top of the core support plate, a core ejection cylinder located at the bottom of the machine housing at the core support plate, and a demolding mechanism located on one side of the machine housing corresponding to the position of the core support plate, the demolding mechanism including a slide rail plate, the slide rail plate being fixed on the machine housing, and a demolding plate being slidably mounted on the upper end of the slide rail plate.

[0006] Furthermore, the turret mechanism also includes a fixing plate, the bottom of the rotating core ejection cylinder is fixed with the fixing plate, and the upper end of the fixing plate is provided with a guide plate. The extended end of the rotating core ejection cylinder passes through the guide plate, and both the fixing plate and the guide plate are fixed inside the machine housing.

[0007] Furthermore, a motor is fixed at the center of the fixed plate, and a rotating core is fixed at the output end of the motor. The rotating core of the motor is fixedly connected to the bottom center of the rotating core support plate.

[0008] Furthermore, a connecting plate is fixed to the top of the plastic part auxiliary tool, and ear plates are fixed to both ends of the connecting plate. The ear plates of the connecting plate on the two right-angled sides of the rotating core support plate are staggered vertically.

[0009] Furthermore, the ear plate has screw holes on its surface, and the screw holes of the two right-angled sides of the ear plate are on the same vertical line. The screw holes are threaded with fixing bolts, and the bottom of the fixing bolts is inserted into the top surface of the rotating core support plate.

[0010] Furthermore, the demolding mechanism also includes a demolding cylinder, which is fixed to the bottom of the slide rail plate, and the extended end of the demolding cylinder is fixedly connected to the demolding plate.

[0011] Furthermore, a plastic protective cover is fixed to the rear end of the template, and the plastic protective cover slides along the surface of the slide rail plate.

[0012] Furthermore, a launch device is provided on the top of the turret mechanism, and the launch device is fixedly connected to the chassis via a mounting bracket.

[0013] The beneficial effects of this utility model are:

[0014] 1. The plastic auxiliary tools on all four sides of the rotating core tray of this utility model are connected to the connecting plate. The ear plates on both sides of the connecting plate are aligned with the upper and lower sides of the two right-angled sides of the connecting plate. At the same time, the screw holes are on a straight line. The two ear plates can be locked by the fixing bolts while the fixing bolts are fixed on the rotating core tray, so that the four connecting plates and the plastic auxiliary tools are fixedly installed on the rotating core tray at the same time.

[0015] 2. When the plastic part needs to be demolded, the demolding cylinder moves forward, the demolding plate moves forward under the action of the guide rail, and the plastic part is taken out under the pushing action of the demolding plate and falls into the plastic part cover, thus completing the demolding.

[0016] 3. When replacing plastic auxiliary tools, this utility model allows for the selection of used and unused plastic auxiliary tools. The ear plate of the top connecting plate of the unused plastic auxiliary tool is separated from the plastic auxiliary tool with two right-angled sides, so that the remaining used plastic auxiliary tools can be removed as a whole. The plastic auxiliary tools with all four sides can be removed and replaced at the same time, or they can be removed and replaced individually or in multiple groups, which improves the convenience of disassembling and installing plastic auxiliary tools.

[0017] 4. The rotating core support plate of this utility model requires auxiliary tools for installing plastic parts. After the mold is closed and injection molding is completed, the mold is opened, the rotating core ejector cylinder moves the rotating core support plate upward to lift the plastic part, the motor drives the rotating core support plate to rotate, and rotates to the next plastic part auxiliary tool that has not been injected. The rotating core ejector cylinder moves downward, and the plastic auxiliary tool that has not been injected will fit with the mold. The mold is closed and the injection molding continues.

[0018] 5. Compared with the prior art, this utility model can automatically complete plastic injection and demolding when plastic parts in a vertical injection molding machine require auxiliary tools for molding, thus automating production, increasing production efficiency, and facilitating quick replacement of auxiliary tools for plastic parts.

[0028] Please see Figures 1 to 7This utility model provides a technical solution: a vertical injection molding machine with a turret mechanism, including a machine housing 1. A turret mechanism 3 is installed on the top surface of the machine housing 1. The turret mechanism 3 includes a core support plate 35. Two sets of plastic part auxiliary tools 36 are installed on the four sides of the top of the core support plate 35. A core ejection cylinder 34 is provided at the bottom of the core support plate 35 in the machine housing 1. A demolding mechanism 4 is provided on one side of the machine housing 1 corresponding to the position of the core support plate 35. The demolding mechanism 4 includes a slide rail plate 41. Fixed on the chassis 1, and the upper end of the slide rail plate 41 is slidably installed with the ejector plate 43. The top of the turret mechanism 3 is provided with the injection device 2, and the injection device 2 is fixedly connected to the chassis 1 through the mounting bracket. In this solution, the injection device 2 is the same as the injection system principle of the existing vertical injection molding machine. After the turret mechanism 3 closes the mold, the plastic auxiliary tool and the mold fit together to complete the injection molding. After the injection molding is completed, it is ejected and demolded by the demolding mechanism 4. The turret mechanism 3 rotates to replace the new plastic auxiliary tool, and the mechanical energy can continuously perform injection molding.

[0029] In this embodiment, the turret mechanism 3 further includes a fixed plate 31. The bottom of the rotating core ejection cylinder 34 is fixed with the fixed plate 31, and a guide plate 33 is provided at the upper end of the fixed plate 31. The extended end of the rotating core ejection cylinder 34 passes through the guide plate 33, and both the fixed plate 31 and the guide plate 33 are fixed inside the housing 1. A motor 32 is fixed at the center of the fixed plate 31, and a rotating core is fixed at the output end of the motor 32. The rotating core of the motor 32 is fixedly connected to the bottom center of the rotating core support plate 35. The rotating core support plate 35 requires auxiliary tools to install plastic parts. After the mold is closed and injection molding is completed, the mold is opened. The rotating core ejection cylinder 34 moves the rotating core support plate 35 upward to lift the plastic part. The motor 32 drives the rotating core support plate 35 to rotate to the next plastic part auxiliary tool 36 that has not been injected. The rotating core ejection cylinder 34 moves downward, and the plastic auxiliary tool that has not been injected will fit with the mold. The mold is closed and injection molding continues.

[0030] In this embodiment, a connecting plate 37 is fixed to the top of the plastic part auxiliary tool 36, and ear plates 38 are fixed to both ends of the connecting plate 37. The ear plates 38 of the connecting plate 37 on the two right-angled sides of the rotating core support plate 35 are staggered vertically. Screw holes 310 are opened on the surface of the ear plates 38. The screw holes 310 of the two right-angled sides of the ear plates 38 are on the same vertical line, and a fixing bolt 39 is threaded into the screw hole 310. The bottom of the fixing bolt 39 is inserted into the top surface of the rotating core support plate 35. The plastic part auxiliary tools 36 on all four sides of the rotating core support plate 35 are connected to the connecting plate 37. The ear plates 38 on both sides of the connecting plate 37 are vertically aligned with the ear plates 38 of the connecting plate 37 on the two right-angled sides. At the same time, the screw holes 310 are also aligned vertically. On a straight line, the two ear plates 38 can be locked by the fixing bolt 39 while the fixing bolt 39 is fixed to the rotating core plate 35, so that the four connecting plates 37 and the plastic part auxiliary tool 36 can be fixedly installed on the rotating core plate 35 at the same time. When replacing the plastic part auxiliary tool 36, the used and unused plastic part auxiliary tools 36 can be selected. The ear plates 38 of the top connecting plate 37 of the unused plastic part auxiliary tool 36 are separated from the two right-angled plastic part auxiliary tools 36, so that the remaining used plastic part auxiliary tools 36 can be directly removed as a whole. The plastic part auxiliary tools 36 on all four sides can be removed and replaced at the same time, or they can be removed and replaced individually or in multiple groups, which improves the convenience of disassembling and installing the plastic part auxiliary tools 36.

[0031] In this embodiment, the demolding mechanism 4 further includes a demolding cylinder 42. The demolding cylinder 42 is fixed to the bottom of the slide rail plate 41, and the extended end of the demolding cylinder 42 is fixedly connected to the demolding template 43. A plastic part cover 44 is fixed to the rear end of the demolding template 43, and the plastic part cover 44 slides along the surface of the slide rail plate 41. When the plastic part needs to be demolded, the demolding cylinder 42 moves forward, and the demolding template 43 moves forward under the action of the guide wire of the slide rail plate 41. The plastic part is taken out under the pushing action of the demolding template 43 and falls into the plastic part cover 44, thus completing the demolding.

[0032] When using the device, auxiliary tools are needed to install the plastic part on the rotating core support plate 35. After the mold is closed and injection molding is completed, the mold is opened, and the rotating core ejector cylinder 34 moves the rotating core support plate 35 upward to lift the plastic part. The motor 32 drives the rotating core support plate 35 to rotate to the next auxiliary tool 36 for the plastic part that has not been injected. The rotating core ejector cylinder 34 moves downward, and the auxiliary tool for the plastic part that has not been injected will fit with the mold. The mold is closed and injection molding continues. When the plastic part needs to be demolded, the demolding cylinder 42 moves forward, and the demolding plate 43 moves forward under the action of the guide rail plate 41. The plastic part is demolded by the demolding plate 43. Under the pushing action, it is taken out and falls into the plastic part cover 44, and the demolding is completed. When changing the plastic part auxiliary tool 36, you can choose to use and unused plastic part auxiliary tools 36. Separate the ear plate 38 of the top connecting plate 37 of the unused plastic part auxiliary tool 36 from the plastic part auxiliary tool 36 with two right angle sides, so that the remaining used plastic part auxiliary tools 36 can be directly removed as a whole. The plastic part auxiliary tools 36 with four sides can be removed and replaced at the same time, or they can be removed and replaced individually or in multiple groups, which improves the convenience of disassembling and installing the plastic part auxiliary tools 36.
