Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a mold for processing plastic handles for automotive interiors. Background Technology

[0002] As an important functional component inside a car, automotive interior plastic handles are typically manufactured using injection molding. In traditional injection molding, the plastic handle needs to be removed from the mold after molding. However, because freshly molded plastic handles are very hot, frequent manual removal is not only inconvenient but also poses a risk of burns, impacting production efficiency and worker safety.

[0003] To address this issue, existing technologies typically incorporate auxiliary material-grabbing grippers on the outside of the injection mold, using mechanical structures to replace manual material handling. For example, pneumatic or electric clamps are used to grip the molded plastic handle, reducing manual intervention.

[0004] However, existing auxiliary material handling grippers still have certain shortcomings in actual operation. Typically, the material handling process of an auxiliary material handling gripper includes three basic actions: clamp positioning, clamp gripping, and clamp retraction. However, the control design of existing material handling grippers is relatively decentralized. For example, the movement, clamping, and resetting of the clamp are achieved by different control mechanisms at different operating positions, making it impossible for the operator to complete all actions from a single centralized location. This not only increases operational complexity but may also affect material handling efficiency and even lead to product damage or mold damage due to improper operation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0006] A mold for processing plastic handles for automotive interiors includes a rotating rod, one end of which is disposed on one side of a lower mold, and the other end of which is disposed on a clamp. The rotating rod rotates around one end to rotate the clamp above the lower mold, and the rotating rod can slide vertically to connect the clamp to a molded handle on the lower mold.

[0007] The clamp includes a base plate and a sliding plate. The base plate is fixedly connected to the rotating rod, and the sliding plate is slidably disposed on the base plate and forms a clamping space with the base plate for release and separation from the handle.

[0008] A grip is slidably mounted on the rotating rod. The sliding direction of the grip is the same as that of the skateboard, and the grip is connected to the skateboard via a connector to drive the skateboard to slide synchronously.

[0009] As a preferred embodiment of this utility model, the rotating rod includes a horizontal bar and a first vertical bar and a second vertical bar disposed at both ends of the horizontal bar. The first vertical bar is fixedly connected to the clamp, and the second vertical bar is inserted into the sleeve seat. The second vertical bar is axially rotatably connected to the sleeve seat. The sleeve is fixedly disposed on one side of the lower mold, and a limiting member is provided at the bottom of the second vertical bar to restrict the second vertical bar from coming out of the sleeve seat.

[0010] As a preferred embodiment of this utility model, a first limiting baffle is provided on the second vertical rod, and a second limiting baffle is provided on the lower mold. When the first limiting baffle and the second limiting baffle are connected, the clamping space is located directly above the handle.

[0011] As a preferred embodiment of this utility model, a sliding groove is provided on the crossbar, an embedded groove is provided in the sliding groove, a bearing is slidably disposed in the embedded groove, and the handle is disposed in the bearing.

[0012] As a preferred embodiment of this utility model, a movable locking structure is provided on the side of the sliding groove away from the clamp, the movable locking structure being used to limit the grip and the slide plate to the position of the clamping handle.

[0013] In a preferred embodiment of this utility model, the connecting member is an L-shaped rigid connecting rod.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention integrates a handle onto a rotatable and height-adjustable lever, and links the handle with the clamp for control. This allows the operator to control the rotation and height of the lever and the opening and closing of the clamp by simply gripping a single handle, thereby simultaneously controlling the positioning, gripping, and resetting actions of the clamp. This effectively solves the problems of scattered control terminals and cumbersome operation in existing auxiliary material handling grippers. It not only simplifies the material handling process and avoids the trouble of switching control in multiple steps, but also significantly improves the continuity of material handling actions and operational efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figure 1 As shown, this embodiment provides a mold for processing plastic handles for automotive interiors, including an upper mold, a lower mold 2, and a rotating rod 1 disposed on one side of the lower mold 2. One end of the rotating rod 1 is disposed on one side of the lower mold 2, and the other end is connected to a clamp 3. The rotating rod 1 can rotate around its end disposed on the lower mold 2, thereby driving the clamp 3 to move horizontally to a position directly above the molded handle 4 above the lower mold 2. In addition, the rotating rod 1 is also designed to slide vertically (i.e., perpendicular to the plane of the lower mold 2) to achieve contact and separation between the clamp 3 and the molded handle 4. Specifically, the rotating rod 1 can be made of high-strength stainless steel to ensure its stability and durability during frequent rotation and sliding. The vertical sliding stroke of the rotating rod 1 is adjusted according to the actual height of the molded handle 4 to ensure that the clamp 3 can accurately connect to the surface of the handle 4.

[0025] The clamp 3 includes a base plate 5 and a sliding plate 6. It can be used as follows: Figure 1 As shown, the base plate 5 is L-shaped and fixedly connected to the free end of the rotating rod 1 by bolts or welding, serving as the fixing base for the clamp 3. The sliding plate 6 is slidably mounted on the base plate 5 via a groove, forming an adjustable clamping space 7 between the sliding plate 6 and the base plate 5 for clamping the molded plastic handle 4. The size of the clamping space 7 can be adjusted by sliding the sliding plate 6 to facilitate clamping the handle 4 and accommodate handles 4 of different sizes.

[0026] like Figure 1 As shown, the grip 8 is slidably mounted on the rotating rod 1, and its sliding direction is consistent with the sliding direction of the slide plate 6 in the clamp 3 to achieve synchronous movement. The grip 8 is mechanically connected to the slide plate 6 through the connector 19, so that by operating the grip 8, the slide plate 6 can be slid to complete the opening and closing action of the clamping space 7, realizing the clamping and releasing of the handle 4. In specific implementation, the grip 8 can be designed as an ergonomic cylindrical handle with a surface covered with non-slip rubber material to facilitate the operator's application of force. The sliding stroke of the grip 8 is consistent with that of the slide plate 6 to ensure precise and efficient clamping action.

[0027] In actual operation, the operator only needs to grasp a single handle 8, then operate the rotating rod 1 to rotate it above the handle 4, and then apply downward force to press the rotating rod 1 down so that it is aligned with the handle 4. Finally, move the handle 8 away from the clamp 3, which will drive the slide plate 6 to move through the connecting piece 19 and clamp the handle 4 in the clamping space 7. Finally, move the handle 8 upward to drive the handle 4 to demold. Finally, rotate the rotating rod 1 to take the handle 4 away from the lower mold 2 to realize the material removal. The operator only needs to operate the handle 4 to complete all the actions in the whole process, which is simple to operate.

[0028] In existing technologies, there are many ways to achieve both rotation and telescopic movement of the rotating rod 1. For example, the telescopic movement of the rotating rod 1 can be achieved through a linear slide rail, and the rotation of the rotating rod 1 can be achieved through a bearing 17 or a rotating structure. However, the implementation of the above methods is relatively complex, and the manufacturing and maintenance costs are high, although they are not convenient. Therefore, a specific structural design for the rotating rod 1 is further presented. Specifically, the rotating rod 1 includes three parts: a horizontal rod 9, a first vertical rod 10, and a second vertical rod 11. The horizontal rod 9 is the horizontal part of the rotating rod 1, connecting the first vertical rod 10 and the second vertical rod 11. The first vertical rod 10 and the second vertical rod 11 are located at both ends of the horizontal rod 9, and their lengths are designed according to the mold dimensions. The horizontal rod 9 adopts a rectangular or circular cross-section to provide sufficient rigidity.

[0029] like Figure 1 As shown, the first vertical rod 10 is fixedly connected to one end of the horizontal rod 9 and is fixedly connected to the base plate 5 of the clamp 3 by bolts or welding. The second vertical rod 11 is disposed at the other end of the horizontal rod 9 and is inserted into the sleeve seat 12 fixed to one side of the lower mold 2. The sleeve seat 12 has a cylindrical structure, ensuring that the second vertical rod 11 can rotate freely around its axis while supporting vertical sliding. A limiting element, such as a limiting ring, is provided at the bottom of the second vertical rod 11 to prevent the second vertical rod 11 from completely dislodging from the sleeve seat 12. The diameter of the limiting element is slightly larger than the inner diameter of the sleeve seat 12, thereby achieving a reliable limiting function.

[0030] Example 2

[0031] like Figure 1As shown, based on Embodiment 1, this embodiment adds a limiting stop to further improve the positioning accuracy of the fixture 3. Specifically, the first limiting stop 13 is disposed on the outer surface of the second longitudinal rod 11, for example, fixed to the middle position of the second longitudinal rod 11 by welding or threaded connection. The first limiting stop 13 has an inverted L-shaped structure as shown in the figure, leaving a distance for the second longitudinal rod 11 to slide, preventing the first limiting stop 13 from interfering with the sleeve. The second limiting stop 14 is fixedly disposed on the side of the lower mold 2, corresponding to the position of the first limiting stop 13. When the rotating rod 1 rotates to the position of the clamping space 7 directly above the forming handle 4, the first limiting stop 13 and the second limiting stop 14 contact each other, forming a mechanical limit, ensuring the accuracy of the clamping action, so that the operator can achieve precise positioning of the fixture 3 without visual inspection or multiple adjustments, significantly improving the material handling efficiency, and reducing the risk of damage to the handle 4 or mold due to positioning errors.

[0032] Example 3

[0033] like Figure 2 and Figure 3 As shown, this embodiment improves the ease of use of the handle 8, making it more ergonomic for operators in practical applications. Based on embodiment 2, this embodiment further designs a sliding structure on the crossbar 9. Specifically, a sliding groove 15 is provided on the crossbar 9, which is a rectangular groove along the length of the crossbar 9. The inner walls on both sides of the sliding groove 15 are recessed inward to form an embedded groove 16 for accommodating the bearing 17.

[0034] The bearing 17 is slidably disposed within the inner groove 16. It is either a ball bearing 17 or a sliding bearing 17. The outer diameter of the bearing 17 matches the width of the inner groove 16 to ensure smooth sliding without significant wobble. The handle 8 is mounted on the bearing 17, allowing the handle 8 to slide stably along the sliding groove 15 while also rotating.

[0035] The rotating handle 8 makes it more convenient for the operator to operate with one hand. When the operator is operating, the handle 8 can always rotate the crossbar 9 with its tip facing the operator. That is, the handle 8 can be held by the operator in a state perpendicular to the crossbar 9. After the crossbar 9 is rotated to the point where it is displaced from the handle 4, the handle 8 can be parallel to the crossbar 9, which makes it more convenient to use.

[0036] Furthermore, the connector 19 employs an L-shaped rigid link, with one end rotatably connected to the bottom of the handle 8. This L-shaped rigid link ensures stable force transmission and eliminates the need for a reversing structure to adjust the direction of the connector 19. For example, when the connector 19 uses a traction rope, the rope connects the slide plate 6 and the handle 8 in a straight line, making it easier for the rope to rub against the substrate 5 when the handle 8 moves. One end of the L-shaped link is rotatably connected to the bottom of the handle 8, and the other end is connected to the slide plate 6. The L-shaped design of the link makes the force transmission path more compact, reducing the risk of deviation during sliding. This allows the sliding action to be transmitted efficiently and accurately to the slide plate 6, ensuring that the opening and closing of the clamping space 7 is completely consistent with the operator's intention, further improving the ease of mold operation.

[0037] Example 4

[0038] like Figure 3 As shown, based on embodiment 3, this embodiment adds a movable locking structure 18 to ensure that after the handle 8 drives the slide plate 6 to move and fixes the handle 4, the position of the handle 8 can be limited to prevent it from sliding close to the clamp 3 and releasing the handle 4.

[0039] Specifically, the movable locking structure 18 is located within the sliding groove 15 on the side away from the clamp 3 (i.e., the end closest to the second longitudinal rod 11). This structure can be in the form of a spring-loaded ball or a rotatable locking plate. For greater ease of use, a spring-loaded ball structure with a certain resistance can be used, for example. The spring-loaded ball includes a ball protruding from the side of the sliding groove 15 and a spring located on the side of the sliding groove 15. The protruding ball provides resistance to prevent the handle 8 from sliding, while applying greater force to slide the ball can press it down, thus allowing it to slide. Its working principle is similar to the ball on an umbrella rib, making it more flexible in actual use.

[0040] With the movable locking structure 18, the clamp 3 can maintain a stable clamping state when clamping the handle 4, avoiding loosening due to external force or vibration, thereby improving the safety and reliability of the material handling process.

[0041] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
