Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a linking structure for an injection mold for new energy vehicles. Background Technology

[0002] A mold is a tool used to create shaped objects. Car storage boxes are produced using injection molds. Because storage boxes are deep-cavity products, after the storage box is injection molded and cooled, it needs to be ejected completely from the cavity through a combination of primary and secondary ejection. However, both ejection processes require two different hydraulic cylinders to drive them, which increases the production cost of the mold.

[0003] The prior art patent application with publication number CN215283109U discloses an injection mold for new energy vehicles, including an upper mold, a lower mold, a positioning rod, a positioning hole, and an extrusion mechanism. This utility model utilizes the positioning rod and positioning hole, and through the cooperation of the extrusion mechanism, after completing one ejection, the extrusion mechanism separates the positioning rod from the positioning hole, allowing the hydraulic cylinder to continue driving the vertical ejector rod to rise for a second ejection. Both ejections can be completed using only one hydraulic cylinder, reducing the production cost of the mold.

[0004] However, in the existing technology, when the mold is closed, the operator needs to manually pick up the upper mold for alignment and adjustment. Manual mold closing may cause deviation between the upper and lower molds, which reduces the practicality of the device. Utility Model Content

[0005] The purpose of this utility model is to provide a connection structure for injection molds of new energy vehicles, which aims to solve the problem that in the prior art, when the mold is closed, the operator needs to manually pick up the upper mold for alignment and adjustment, which may cause deviation between the upper and lower molds, reducing the practicality of the device.

[0006] To achieve the above objectives, this utility model provides a connection structure for an injection mold of a new energy vehicle, including an upper mold, a lower mold, and a connecting mechanism. The connecting mechanism includes two first mounting plates, two second mounting plates, two support rods, a support plate, a pull rod, and two locking components. The upper mold is located above the lower mold. The two first mounting plates are fixedly connected to both ends of the lower mold, and the two second mounting plates are fixedly connected to both ends of the upper mold. The two support rods are fixedly connected to the two first mounting plates and slidably connected to the two second mounting plates. The two ends of the support plate are fixedly connected to the two support rods and are located above the upper mold. The pull rod is fixedly connected to the upper mold and slidably connected to the support plate, extending above the support plate. The two locking components are disposed at both ends of the upper mold.

[0007] The locking assembly includes a fixed plate, a telescopic kit, a movable frame, and a fixed rod. The support rod has two fixing holes, the upper mold has two mounting slots, the fixed plate is fixedly connected to the upper mold and located at one end of the mounting slots, the telescopic kit is disposed between the fixed plate and the movable frame, the fixed rod is fixedly connected to the movable frame, and one end of the fixed rod is slidably connected to the support rod and located in the fixing hole.

[0008] The telescopic kit includes a telescopic spring and a telescopic rod. The two ends of the telescopic spring are fixedly connected to the fixed plate and the movable frame, respectively. The two ends of the telescopic rod are fixedly connected to the fixed plate and the movable frame, respectively, and are located inside the telescopic spring.

[0009] The locking component further includes a slider and a slide groove. The slide groove is disposed on the upper mold and located in the mounting groove. The slider is fixedly connected to the movable frame and slidably connected to the upper mold, and is located in the slide groove.

[0010] The connecting mechanism further includes two limiting posts. The lower mold has two limiting holes located above it. The two limiting posts are fixedly connected to both ends of the upper mold and located below it. The two limiting posts are slidably connected to the lower mold.

[0011] This utility model discloses a connection structure for an injection mold of a new energy vehicle. When the mold is closed, pulling the pull rod upwards controls the two locking components to disengage the upper mold from the two support rods. The operator then slowly moves the pull rod downwards, causing the upper mold to move towards the lower mold until they are tightly fitted together. At this point, the two locking components reconnect and fix the upper mold to the two support rods, ensuring that the upper and lower molds will not separate during injection molding. This method of mold closing eliminates the need for manual alignment and adjustment by the operator, avoiding deviations during mold closing and thus increasing the practicality of the device.

Detailed Implementation

[0018] Please refer to Figures 1-2, where, Figure 1 This is a schematic diagram of the connection structure of the injection mold for new energy vehicles according to this utility model. Figure 2 This is a schematic diagram of the connection structure in another direction of the injection mold for new energy vehicles according to this utility model. Figure 3 This is a front view of the connection structure of the injection mold for new energy vehicles according to this utility model. Figure 4 This is a structural schematic diagram of the locking component of this utility model.

[0019] This utility model provides a connection structure for an injection mold of a new energy vehicle, including an upper mold 102, a lower mold 101, and a connecting mechanism. The connecting mechanism includes two first mounting plates 103, two second mounting plates 104, two support rods 105, a support plate 106, two limiting posts 108, a pull rod 107, and two locking components. The lower mold 101 has two limiting holes 109. The locking components include a fixing plate 112, a telescopic kit, a slider 118, a slide groove 117, a moving frame 115, and a fixing rod 116. The support rod 105 has two fixing holes 110. The upper mold 102 has two mounting grooves 111. The telescopic kit includes a telescopic spring 114 and a telescopic rod 113. The aforementioned solution solves the problem in the prior art where, when the mold is closed, the operator needs to manually lift the upper mold 102 for alignment and adjustment. Manual mold closure may cause deviations between the upper mold 102 and the lower mold 101, reducing the practicality of the device.

[0020] In this embodiment, the upper mold 102 is located above the lower mold 101. Two first mounting plates 103 are fixedly connected to both ends of the lower mold 101, and two second mounting plates 104 are fixedly connected to both ends of the upper mold 102. Two support rods 105 are fixedly connected to the two first mounting plates 103 and slidably connected to the two second mounting plates 104. Two ends of a support plate 106 are fixedly connected to the two support rods 105 and are located above the upper mold 102. A pull rod 107 is fixedly connected to the upper mold 102 and slidably connected to the support plate 106, extending above the support plate 106. Two locking components are disposed on the upper mold. At both ends of 102, when the device closes the mold, pulling the pull rod 107 upward controls the two locking components to release the connection between the upper mold 102 and the two support rods 105. The operator slowly moves the pull rod 107 downward, and the upper mold 102 moves towards the lower mold 101 until the upper mold 102 and the lower mold 101 are tightly fitted. At this time, the two locking components reconnect and fix the upper mold 102 to the two support rods 105, ensuring that the upper mold 102 and the lower mold 101 will not separate during the injection molding process. By closing the mold in the above manner, the operator does not need to manually align and adjust it, avoiding deviations when the upper mold 102 and the lower mold 101 are closed, thereby increasing the practicality of the device.

[0021] Furthermore, the fixing plate 112 is fixedly connected to the upper mold 102 and located at one end of the mounting groove 111. The telescopic kit is disposed between the fixing plate 112 and the movable frame 115. The fixing rod 116 is fixedly connected to the movable frame 115. One end of the fixing rod 116 is slidably connected to the support rod 105 and located in the fixing hole 110.

[0022] Furthermore, the two ends of the telescopic spring 114 are fixedly connected to the fixed plate 112 and the movable frame 115 respectively, and the two ends of the telescopic rod 113 are fixedly connected to the fixed plate 112 and the movable frame 115 respectively, and are located inside the telescopic spring 114.

[0023] In this embodiment, when the device closes the mold, the pull rod 107 is pulled upwards, and the moving frame 115 is pulled away from the support rod 105. The telescopic spring 114 and the telescopic rod 113 are compressed, and the fixing rod 116 moves out of the fixing hole 110. Then, the other fixing rod 116 is moved out of the fixing hole 110 in the same way. The connection between the upper mold 102 and the two support rods 105 is released. The operator slowly moves the pull rod 107 downwards, and the upper mold 102 moves towards the lower mold 101 until the upper mold 102 and the lower mold 101 are tightly fitted. At this time, the fixing rod 116 moves to the side of the fixing hole 110 located below the support rod 105. Under the action of its own elastic potential energy, the telescopic spring 114... The upper mold 102 extends and moves the fixing rod 116 toward the fixing hole 110. The two fixing rods 116 are respectively inserted into the two fixing holes 110. The upper mold 102 is reconnected and fixed to the two support rods 105 to ensure that the upper mold 102 and the lower mold 101 will not separate during the injection molding process. The mold is closed in the above manner without the need for manual alignment and adjustment by the operator, avoiding deviations when the upper mold 102 and the lower mold 101 are closed, thereby increasing the practicality of the device. When the mold is opened, the same method is used. The two fixing rods 116 are respectively inserted into the two fixing holes 110 located above the two support rods 105, so that the upper mold 102 is fixed above the lower mold 101, so that the operator can remove the workpiece.

[0024] Furthermore, the slide groove 117 is disposed on the upper mold 102 and located in the mounting groove 111, the slider 118 is fixedly connected to the movable frame 115, the slider 118 is slidably connected to the upper mold 102 and located in the slide groove 117.

[0025] In this embodiment, when the movable frame 115 moves, the slider 118 slides within the slide groove 117. The slider 118 and the slide groove 117 limit and guide the movement of the movable frame 115 and the fixed rod 116. At the same time, the two fixed rods 116 bear the weight of the upper mold 102. The slide groove 117 is arranged in a cross shape to ensure that the slider 118 is stuck within the slide groove 117, thereby ensuring that the fixed rod 116 will not deform, thus increasing the structural stability of the device.

[0026] Furthermore, the two limiting posts 108 are fixedly connected to both ends of the upper mold 102 and located below the upper mold 102, and the two limiting posts 108 are slidably connected to the lower mold 101.

[0027] In this embodiment, when the upper mold 102 approaches the lower mold 101, the two limiting posts 108 are respectively inserted into the two limiting holes 109. The two limiting posts 108 and the two limiting holes 109 play a limiting and guiding role in the movement of the upper mold 102.

[0028] When using this invention, during mold closing, pulling the pull rod 107 upwards pulls the movable frame 115 away from the support rod 105, compressing the telescopic spring 114 and the telescopic rod 113. The fixing rod 116 moves out of the fixing hole 110, and then the other fixing rod 116 is moved out of the fixing hole 110 in the same manner. The connection between the upper mold 102 and the two support rods 105 is released. The operator slowly moves the pull rod 107 downwards, moving the upper mold 102 towards the lower mold 101 until the upper mold 102 and the lower mold 101 are tightly fitted. At this point, the fixing rod 116 moves... When the spring 114 moves to the side of the fixing hole 110 located below the support rod 105, it extends under the action of its own elastic potential energy, and drives the fixing rod 116 to move towards the fixing hole 110. The two fixing rods 116 are respectively inserted into the two fixing holes 110. The upper mold 102 is reconnected and fixed to the two support rods 105, ensuring that the upper mold 102 and the lower mold 101 will not separate during the injection molding process. The mold is closed in the above manner without the need for manual alignment and adjustment by the operator, avoiding deviations when the upper mold 102 and the lower mold 101 are closed, thereby increasing the practicality of the device.

Those skilled in the art will understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
