Technical Field

[0001] This utility model relates to the technical field of injection mold feeding mechanisms, and in particular to an injection mold feeding mechanism that can flexibly swing. Background Technology

[0002] Injection molds are complex and precise tools that integrate mechanics, thermodynamics, and materials science. Their principle is to efficiently and repeatedly complete the shaping, cooling, and demolding processes of polymer materials through a precise metal system. In the production of some injection molded parts, a feeding mechanism is needed to accurately place a pre-processed insert into the designated position of the mold to meet the production requirements of the corresponding injection molded part.

[0003] Existing injection mold feeding mechanisms typically use a track-type drive mechanism to adjust the position of the gripper. This means that whether the gripper is pneumatic or electrically controlled, an adjustable-length connecting line or pipe is often required to control the gripper's operation, making the maintenance of the injection mold feeding mechanism very troublesome.

[0015] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Example

[0016] Reference Figure 1 , Figure 2 and Figure 3 The present invention discloses an injection mold feeding mechanism that can flexibly swing, comprising: an outer ring 1, an inner plate 2 rotatably mounted inside the outer ring 1, a plurality of piston cylinders 3 being threaded through the outer ring 1 at equal intervals, a piston plate 4 being slidably mounted inside the piston cylinder 3, and the bottom side of the piston plate 4 being fixedly connected to the inner bottom wall of the piston cylinder 3 through an elastic element 5, and a round tube 6 being fixedly mounted at the center of the bottom side of the piston plate 4, and the bottom of the round tube 6 extending to the bottom of the corresponding piston cylinder 3 and threadedly mounted with a pneumatic gripper 10; The one-way pressure relief valve 11 and the push-button pressure relief valve 12 are symmetrically fixed and installed through the top side of the piston plate 4, and their interiors are connected to the interiors of the corresponding circular tubes 6. The drive mechanism 7 is located on the outer periphery of the middle part of the inner plate 2 and is used to drive the outer ring 1 to rotate. The air injection mechanism 8 and the adjustment mechanism 9 are symmetrically arranged on the outer periphery of the top of the inner plate 2, and are used for air injection into the piston cylinder 3, height adjustment of the circular tube 6, and pressing of the press-type pressure relief valve 12, respectively.

[0017] In this embodiment (please refer to...), Figure 1 As shown, the inner plate 2 is connected to the injection mold placement platform through the existing track-type adjustment mechanism. When the improved injection mold feeding mechanism is used, the overall position of the device is adjusted through the track-type adjustment mechanism, and multiple inserts or multiple inserts of the same type are grabbed at one time by the rotation of the outer ring 1. With the overall displacement of the device and the rotation of the outer ring 1, the inserts are placed in the injection mold, and then the injection of the injection part is completed according to the existing injection mold usage method. The aforementioned insert gripping method involves driving the outer ring 1 to rotate via the drive mechanism 7 (which mainly consists of a servo motor, gears, a gear ring, and a baffle plate). This sequentially moves the piston cylinder 3 below the gas injection mechanism 8. Subsequently, the gas injection mechanism 8 is activated, injecting a corresponding amount of gas into the piston cylinder 3. Due to the obstruction of the one-way pressure relief valve 11 and the push-type pressure relief valve 12, the gas injected into the piston cylinder 3 first forms a high-pressure chamber at the top of the piston cylinder 3. The gas can push the piston plate 4, pushing the circular tube 6 out of the piston cylinder 3, thereby driving the pneumatic gripper 10 to move downwards, allowing the pneumatic gripper 10 to move into the material box. At the position of the insert, as the pressure inside the piston cylinder 3 further increases, after the pressure difference across the one-way pressure relief valve 11 reaches the threshold, some of the gas inside the piston cylinder 3 flows through the one-way pressure relief valve 11 into the circular tube 6, and the circular tube 6 guides the gas into the pneumatic gripper 10 to start the pneumatic gripper 10 to complete the gripping of the insert. Then the drive mechanism 7 continues to drive the outer ring 1 to rotate, moving the piston cylinder 3 away from the bottom side of the gas injection mechanism 8. At this time, the gas inside the piston cylinder 3 flows out from the top opening of the piston cylinder 3. At this time, the elastic element 5 pushes the piston plate 4 upward, driving the circular tube 6 to retract into the piston cylinder 3 until the piston plate 4 and the inner wall of the piston cylinder 3 come into contact with each other. The above-mentioned method of placing the insert into the injection mold is as follows: by rotating the outer ring 1, the piston cylinder 3 is moved sequentially to the lower part of the adjusting mechanism 9. Then, the adjusting mechanism 9 is activated to push the piston plate 4 downward by a corresponding distance. The insert is moved into the corresponding position in the injection mold through the round tube 6 and the gripper. Then, the adjusting mechanism 9 presses the pressure relief valve 12. Excess gas in the round tube 6 and the pneumatic gripper 10 flows out from the pressure relief valve and out from the top opening of the piston cylinder 3 to complete the pressure relief in the pneumatic gripper 10, thereby disconnecting the insert from the pneumatic gripper 10. Then, the adjusting mechanism 9 releases the downward state of the piston plate 4, and the elastic element 5 drives the piston plate 4 to move upward and reset, so as to remove the gripper from the injection mold. In summary, this improved injection mold feeding mechanism can pick up multiple inserts or various types of inserts and place inserts in one or more injection molds by rotating and moving the outer ring 1. Moreover, the device has a simple structure and does not require long pipelines. Controlling the operation of the pneumatic gripper 10 facilitates the maintenance of the injection mold feeding mechanism.

[0018] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the elastic element 5 includes a limiting cylinder 51 and a spring 52. The limiting cylinder 51 is fixedly installed in the bottom opening of the corresponding piston cylinder 3, and the two ends of the spring 52 are fixedly connected to the inner bottom wall of the corresponding limiting cylinder 51 and the corresponding piston plate 4, respectively. In this embodiment, please refer to Figure 3As shown, the limiting cylinder 51 can constrain the maximum downward movement of the piston plate 4 to prevent the piston plate 4 from sliding out of the piston cylinder 3 and to lock the maximum length of the circular tube 6 and the piston cylinder 3 as a whole. After the external force on the piston plate 4 disappears (i.e., the pushing force of the gas in the piston cylinder 3 on the piston plate 4 or the downward pressure of the adjusting mechanism 9 on the piston plate 4), the spring 52 stretches upward to push the piston plate 4 and push the round tube 6 into the piston cylinder 3 until the piston plate 4 and the inner wall of the piston cylinder 3 come into contact with each other.

[0019] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the air injection mechanism 8 includes an air pump 81, which is fixedly connected to the outer wall of the top of the inner plate 2 through a connecting plate 82, and the air pump 81's suction end passes through the connecting plate 82. In this embodiment, please refer to Figure 2 and Figure 4 As shown, after the piston cylinder 3 moves below the connecting plate 82, gas is injected into the piston cylinder 3 by the air pump 81. The connecting plate 82 can be used in conjunction with the inner plate 2 to support and limit the air pump 81, so that the distance between the air pump 81 and the outer ring 1 remains unchanged.

[0020] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the air pump 81 is fitted with a sealing gasket 83 at the air extraction end, and the sealing gasket 83 is fixedly connected to the connecting plate 82. The outer ring 1 of the bottom side of the sealing gasket 83 is arc-shaped. In this embodiment, please refer to Figure 2 and Figure 4 As shown, during the process of the piston cylinder 3 moving below the connecting plate 82, the sealing gasket can be squeezed along the arc surface of the sealing gasket in conjunction with the connecting plate 82, so that the bottom side of the sealing gasket fits against the top side of the piston cylinder 3, thereby sealing the gap between the connecting plate 82 and the top side of the piston cylinder 3, and preventing the gas injected into the piston cylinder 3 from flowing out through the gap between the piston cylinder 3 and the connecting plate 82.

[0021] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 5 As shown, the adjustment mechanism 9 includes a driver 91, which is fixedly connected to the outer wall of the top of the inner plate 2 via a limiting plate 92. The driving end of the driver 91 is fixedly installed through a sleeve 93, and the bottom of the sleeve 93 rotates through the limiting plate 92. A motor 94 is fixedly installed above the limiting plate 92 via a support rod. The driving end of the motor 94 is threadedly fitted with a square rod 95 via a threaded rod, and the bottom of the square rod 95 slides through the sleeve 93. In this embodiment, please refer to Figure 2 , Figure 3 and Figure 5As shown, the square rod 95 is driven to move up and down reciprocally through the cooperation of the motor 94 and the threaded rod, thereby cooperating with the spring 52 to drive the round rod to move up and down reciprocally inside the piston cylinder 3; Specifically, the piston cylinder 3 is moved below the limiting plate 92 by the rotation of the outer ring 1. At this time, the motor 94 starts to drive the threaded rod to rotate. Due to the constraint of the actuator 91 and the sleeve 93 on the square rod 95, the square rod 95 cannot rotate with the threaded rod (the actuator 91 is mainly composed of the housing, servo motor, gear ring transmission mechanism and locking mechanism). The rotating threaded rod pushes the square rod 95 to move downward or upward. The piston plate 4 and the round tube 6 can be pushed downward by the mutual contact between the square rod 95 and the piston plate 4, or the piston plate 4 can be driven upward to reset by the spring 52.

[0022] In a further preferred embodiment of this utility model, such as Figure 3 , Figure 5 and Figure 6 As shown, a pressure plate 96 is fixedly installed on the outer wall of the bottom of the square rod 95, and both sides of the pressure plate 96 are arc-shaped. In this embodiment, please refer to Figure 3 , Figure 5 and Figure 6 After the insert is placed into the injection mold, the driver 91 drives the sleeve to rotate 180 degrees, and the square rod 95 rotates together with the inner wall of the sleeve 93 through mutual contact, so as to move the pressing position to the top side of the press-type pressure relief valve 12, so as to complete the pressing of the press-type pressure relief valve 12 through mutual contact between the arc surface of the pressure plate 96 and the pressing end of the press-type pressure relief valve 12 (the press-type pressure relief valve can be a valve core). As the press-type pressure relief valve opens, the excess gas in the pneumatic gripper 10 and the round tube 6 flows into the press-type pressure relief valve. After the pressure relief operation of the pneumatic gripper 10 is completed, the driver 91 continues to drive the sleeve 93 to rotate 180 degrees, so that the pressure plate 96 is reset.

[0023] Working principle: When this improved injection mold feeding mechanism is used, the overall position of the device is adjusted by the track-type adjustment mechanism, and the rotation of the outer ring 1, combined with the telescopic movement of the round rod in the piston cylinder 3, and the opening and closing of the pneumatic gripper 10, grabs multiple inserts or multiple inserts of the same type at one time. With the overall displacement of the device and the rotation of the outer ring 1, the inserts are placed in the corresponding positions in the injection mold. Finally, the injection molding of the injection part is completed according to the existing injection mold usage method.

[0024] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
