Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an adjustable automotive door handle injection mold. Background Technology

[0002] An injection mold for car door handles is a mold used to produce plastic parts for car door handles. It uses injection molding technology to inject molten plastic into the mold, which then cools and solidifies to form the plastic part of the door handle. The design and manufacture of the injection mold have a crucial impact on the quality and performance of the door handle. Currently, by changing and adjusting the mold, door handles of different shapes can be injection molded.

[0003] When using existing injection molds, after the plastic solidifies inside the mold, the surface of the material is tightly adhered to the inner cavity of the mold, which makes it inconvenient to remove the material. The material is easily damaged or deformed when the material is removed with large force or when tools are used. To address these issues, we propose an adjustable automotive door handle injection mold. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable automotive door handle injection mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable car door handle injection mold includes a mold base, a lower mold cavity installed above the mold base, and an upper mold cavity engaged above the lower mold cavity. A toggle mechanism is inserted on both sides of the lower mold cavity, and the end of the toggle mechanism is fixedly connected to the end of the drive mechanism. The side of the drive mechanism meshes with one side of a transmission gear, and the other side of the transmission gear meshes with a pusher mechanism. The transmission gear is mounted in a mounting plate via a rotating shaft.

[0007] Preferably, the actuating mechanism includes connecting rods, with connecting rods inserted into both sides of the lower mold cavity, and a pressing plate fixedly connected to the outer end of the connecting rod.

[0008] Preferably, both sides of the lower mold cavity are provided with strip-shaped through grooves adapted to the connecting rod, and the surface of the pressing plate is larger than the width of the strip-shaped through grooves.

[0009] Preferably, both ends of the pressing plate are provided with round holes, and a limiting rod is inserted into the round holes. The outer end of the limiting rod is fixedly connected to a connecting plate, and the two sides of the lower mold cavity are provided with insertion holes that are compatible with the limiting rod.

[0010] Preferably, two guide sliders are symmetrically fixed to the inner wall of the circular hole, and the surface of the limiting rod is provided with a groove that matches the guide sliders.

[0011] Preferably, the driving mechanism includes a driving column, the end of the connecting rod is fixedly connected to the driving column, and both sides of the driving column are fixedly connected to a first rack. A return spring is welded between the lower surface of the driving column and the inner wall of the lower mold cavity.

[0012] Preferably, the pushing mechanism includes a second rack, the transmission gear meshes with the side of the second rack, a pushing plate is fixedly connected to the top of the second rack, and a limiting plate is fixedly connected to the bottom of the second rack.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device can move the first rack within the lower mold cavity by a toggle mechanism, which in turn can cause the second rack to move in the opposite direction via a transmission gear. This facilitates pushing the pusher plate, which in turn lifts the material formed inside the lower mold cavity for easy removal. Furthermore, a return spring can assist in resetting the action of the toggle mechanism, allowing the pusher plate to return to its original position.

[0015] 2. This device allows for convenient control of the movement of the connecting rod via a pressing plate. The movement of the connecting plate also controls the function of two sets of limiting rods. By inserting the limiting rods into the outer side of the lower mold cavity, the connecting rods can be conveniently limited, preventing accidental activation of the limit. At the same time, the guide slider can guide the limiting rods. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-4 An adjustable car door handle injection mold includes a mold base 1, a lower mold cavity 2 installed above the mold base 1, and an upper mold cavity 3 engaged above the lower mold cavity 2. Actuating mechanisms 4 are inserted on both sides of the lower mold cavity 2, and the ends of the actuating mechanisms 4 are fixedly connected to the ends of the driving mechanisms 5. The actuating mechanisms 4 can conveniently control the action of the driving mechanisms 5. The side of the driving mechanism 5 meshes with one side of a transmission gear 6, and the other side of the transmission gear 6 meshes with a pushing mechanism 8. The transmission gear 6 is installed in a mounting plate 7 via a rotating shaft, and the mounting plate 7 is fixedly connected to the inner wall of the lower mold cavity 2, facilitating the installation of the two transmission gears 6.

[0027] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the actuating mechanism 4 includes a connecting rod 41. The connecting rod 41 is inserted into both sides of the lower mold cavity 2, and the outer end of the connecting rod 41 is fixedly connected to a pressing plate 42. By pressing the pressing plate 42, the movement of the connecting rod 41 can be controlled.

[0028] Furthermore, refer to Figure 3 and Figure 4 It can be seen that both sides of the lower mold cavity 2 are provided with strip-shaped through grooves that are compatible with the connecting rod 41. The surface of the pressing plate 42 is larger than the width of the strip-shaped through grooves. Through the strip-shaped through grooves provided on both sides of the lower mold cavity 2, the connecting rod 41 can move in the strip-shaped through grooves, which facilitates the control of the driving mechanism 5. The pressing plate 42 can also facilitate the driving of the connecting rod 41.

[0029] Furthermore, refer to Figure 3 and Figure 4It can be seen that both ends of the pressing plate 42 are provided with round holes, and a limiting rod 43 is inserted into the round holes. Through the round holes provided at both ends of the pressing plate 42, the limiting rod 43 can be moved along the round holes. The outer end of the limiting rod 43 is fixedly connected to the connecting plate 44. The connecting plate 44 can be used to move the two limiting rods 43. The two sides of the lower mold cavity 2 are provided with insertion holes that are compatible with the limiting rods 43. Through the insertion holes provided on the two sides of the lower mold cavity 2, the limiting rod 43 can be inserted into the insertion holes, which facilitates the function of limiting the pressing plate 42 and prevents the pressing plate 42 from being accidentally touched.

[0030] Furthermore, refer to Figure 3 and Figure 4 It can be seen that two guide sliders 45 are symmetrically fixed on the inner wall of the circular hole, and the surface of the limiting rod 43 is provided with a groove that matches the guide sliders 45. When the limiting rod 43 moves along the inside of the pressing plate 42, the guide sliders 45 can slide along the groove, which plays the role of limiting the guide rod 43.

[0031] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the driving mechanism 5 includes a driving column 51, the end of the connecting rod 41 is fixedly connected to the driving column 51, and the two sides of the driving column 51 are fixedly connected to the first rack 52. A return spring 53 is welded between the lower surface of the driving column 51 and the inner wall of the lower mold cavity 2. Through the multiple sets of return springs 53 welded to the lower surface of the driving column 51, the driving column 51 can be easily pushed to return to its original position.

[0032] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the pushing mechanism 8 includes a second rack 81, a transmission gear 6 meshing with the side of the second rack 81, a pushing plate 82 fixedly connected to the top of the second rack 81, and a limiting plate 83 fixedly connected to the bottom of the second rack 81. By moving the first rack 52, the transmission gear 6 can drive the second rack 81 to move in the opposite direction, so that the pushing plate 82 can push the material up. At the same time, the limiting plate 83 can limit the second rack 81.

[0033] Working principle: When this utility model is in use, when the mold base 1 needs to pick up materials, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4By pulling the connecting plate 44, the limiting rod 43 can be pulled out from the lower mold cavity 2. At this time, pressing the pressing plate 42 can cause the connecting rod 41 to drive the driving column 51 and the first rack 52 to move downward, so that the return spring 53 is in a compressed state. At this time, the transmission gear 6 can cause the first rack 52 to move downward, and the second rack 81 to move upward, so that the second rack 81 can push the pusher plate 82, which can easily lift the material formed inside the lower mold cavity 2 for easy removal. After the material is removed, the pressing plate 42 is released. Through the elastic force of the multiple sets of return springs 53, the driving column 51 can drive the first rack 52 to return to its original position, and the transmission gear 6 can cause the second rack 81 to drive the pusher plate 82 to return to its original position. At this time, pushing the connecting plate 44 can cause the connecting plate 44 to drive the limiting rod 43 to be inserted into both sides of the lower mold cavity 2, which can easily limit the connecting rod 41.

[0034] The above is the complete working principle of this utility model.
