Description

Technical Field

[0001] The present application relates to the technical field of injection molds, and in particular to an injection mold for a push-pull rod housing. Background Art

[0002] As a part installed on the upper door of a car, the push-pull rod can support the open car door, and the injection mold, as a production equipment for producing the push-pull rod shell, plays an important role.

[0003] In the prior art, there is a push-pull rod shell injection mold, which includes a fixed mold, a movable mold, an inner mold and a driving member, and an injection cavity is provided on both the fixed mold and the movable mold. The inner mold is arranged at one end of the fixed mold close to the movable mold, and is slidably connected with the fixed mold, and a protrusion molding groove is also provided inwardly on one end of the inner mold. A sleeve mold is also arranged on the inner mold, and the sleeve mold is located at the end of the end where the protrusion molding groove is located on the inner mold. The inner wall of the sleeve mold is also provided with a molding surface so that the end wall of the push-pull rod shell is formed into a specific shape. The driving member is used to drive the inner mold to slide. When in use, when the injection molded part in the injection mold cavity is completely formed, the fixed mold is away from the movable mold, so that the injection molded part is exposed, and then the driving member drives the inner mold to slide, so that the inner mold drives the sleeve mold to slide together, so that the sleeve mold is separated from the end of the injection molded part, and the inner mold gradually slides out of the injection molded part, so that the relevant personnel can remove the molded push-pull rod shell.

[0004] With regard to the above-mentioned related technologies, since the latch formed on the injection molded part is embedded in the latch molding groove, and the prior art drives the inner mold to slide through the driving part only after the injection molded part is completely molded, so that the inner mold is separated from the molded injection molded part. This means that when the inner mold gradually separates from the injection molded part, the latch on the injection molded part will abut against the latch molding groove, hindering the separation of the injection molded part from the inner mold, which makes it easy for the latch on the injection molded part to be damaged when separated from the inner mold, thereby reducing the molding quality of the injection molded part, so there is room for improvement. Summary of the invention

[0009] By adopting the above technical solution, the locking frame is set so that when the movable mold approaches the fixed mold, the locking frame on the movable mold can be gradually inserted into the locking groove on the sleeve frame in the fixed mold, thereby locking the sleeve frame, reducing the probability of accidental slippage of the sleeve frame during the injection molding process, and effectively ensuring the molding quality of the present application.

[0010] Preferably, the abutment frame is slidably connected to the sleeve frame, and the sliding direction is perpendicular to the sliding direction of the sleeve mold. The sleeve mold is also provided with an abutment groove for the abutment frame to be inserted. The abutment frame is also provided with a locking assembly. The locking assembly is used to drive the abutment frame to slide and be inserted into the abutment groove after the sleeve mold slides to a specified position.

[0011] By adopting the above technical solution, the locking component and the abutment frame are set so that after the sleeve mold slides to the specified position, the locking component can drive the abutment frame to slide, so that the abutment frame is inserted into the abutment groove of the sleeve mold, thereby locking the sleeve mold and the sleeve frame, reducing the probability of accidental slip of the sleeve mold during the injection molding process, and effectively ensuring the molding quality of the present application.

[0013] By adopting the above technical solution and the specific setting of the locking assembly, during the process of the locking frame being gradually inserted into the sleeve frame, the locking frame can abut against the driving frame to push the driving frame to slide, so that the driving frame drives the abutting frame to slide through the linkage member, and the end of the abutting frame is inserted into the abutting groove on the sleeve mold, thereby realizing the fixation between the sleeve mold and the sleeve frame and realizing the linkage between the locking frame and the abutting frame.

[0014] Preferably, the linkage member comprises a linkage frame, one end of the linkage frame is rotatably connected to the driving frame, and the other end of the linkage frame is rotatably connected to the abutting frame.

[0015] By adopting the above technical solution, the linkage frame is set so that when the driving frame slides downward after being driven by the locking frame, the driving frame can drive the linkage frame to rotate relative to itself, so that the end of the linkage frame away from the driving frame is displaced, and then the linkage frame drives the abutting frame to slide, thereby realizing the linkage between the locking frame and the abutting frame, effectively ensuring the fixation between the sleeve frame and the sleeve mold, and reducing the probability of accidental slippage of the sleeve mold during the injection molding process.

[0016] Preferably, the driving frame is further provided with an elastic member, and the elastic member is used for allowing the driving frame to return to an initial position through its own elastic force.

[0017] By adopting the above technical solution and arranging the elastic member, after the locking frame slides outward and disengages from the locking groove, the driving frame can gradually return to its initial position under the elastic force of the elastic member, so that the driving frame drives the abutting frame to slide, so that the abutting frame disengages from the abutting groove, so that the driving member can smoothly drive the sleeve mold to disengage from the end of the initially formed injection molded part, so that the end of the injection molded part can be smoothly opened, effectively ensuring the smooth demolding of the present application.

[0018] Preferably, the locking frame is also provided with an anti-slip mechanism, which includes an anti-slip frame and an anti-slip assembly. The anti-slip frame is located on a side of the locking frame close to the sleeve mold and is slidably connected to the locking frame. The sleeve mold is located on a sliding path of the anti-slip frame. The anti-slip assembly is used to drive the anti-slip frame to slide when the locking frame is inserted into the locking groove.

[0019] By adopting the above-mentioned technical solution and setting the anti-slip mechanism, during the process of the locking frame being inserted into the locking groove, the anti-slip component can drive the anti-slip frame to move relative to the locking frame, so that the anti-slip frame gradually approaches the end of the sleeve mold and finally abuts against the end of the sleeve mold, further reducing the probability of accidental slippage of the sleeve mold, thereby further ensuring the molding effect of the present application.

At this time, the sliding frame drives the rotating frame to rotate through the driving frame, thereby realizing the driving of the rotating frame, effectively realizing the linkage between the abutting frame and the rotating frame, and effectively facilitating the operation of relevant personnel.

[0024] Preferably, when the locking frame is inserted into the sleeve frame, it abuts against a side of the sleeve mold away from the injection molded part.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-8 This application is described in further detail.

[0037] Embodiment 1: Embodiment 1 of the present application discloses a push-pull rod housing injection mold. Figure 1 , Figure 2 and Figure 3 The push-pull rod shell injection mold includes a fixed mold 1, a movable mold 2, an inner mold 3 and a driving member 4, and a sleeve mold 5 is also provided on the inner mold 3. A sleeve frame 6 is also connected to the end of the inner mold 3, and the sleeve mold 5 is located in the sleeve frame 6 and is slidably connected to the sleeve frame 6, and the sliding direction is the sliding direction of the inner mold 3. The end of the sleeve mold 5 extends out of the sleeve frame 6 to be sleeved on the end of the injection molded part (that is, the injection molded push-pull rod shell). The driving member 4 is used to drive the sleeve mold 5 to slide, and an abutment frame 61 is also connected to the sleeve frame 6. The abutment frame 61 is located on the side of the sleeve mold 5 away from the injection molded part, and the abutment frame 61 is located on the displacement path of the sleeve mold 5.

[0038] Reference Figure 1 and Figure 2, a molding cavity is provided on one end of the fixed mold 1 and the movable mold 2 that are close to each other, so that when the fixed mold 1 and the movable mold 2 are attached to each other, a complete cavity is combined. In the embodiment of the present application, the fixed mold 1 is fixedly mounted on the machine body, and the movable mold 2 is connected to the lifting member (i.e., lifting cylinder or oil cylinder) on the machine body. The sleeve frame 6 is slidably connected to the fixed mold 1 through corresponding slide rails, and the sliding direction is the length direction of the fixed mold 1. A connecting frame 62 is provided on the side of the sleeve frame 6 close to the driving member 4, and the connecting frame 62 is fixedly connected to the sleeve frame 6 by bolts.

[0039] Reference Figure 3 and Figure 4 In the embodiment of the present application, the number of the inner molds 3 is set to two, and a protrusion forming groove 31 is provided on one end of each inner mold 3 close to the sleeve frame 6. One end of each of the two inner molds 3 passes through the sleeve frame 6 from the side of the sleeve frame 6 away from the connecting frame 62, and is fixedly connected to the connecting frame 62. In the embodiment of the present application, the driving member 4 is set to be a cylinder, which is fixedly installed on the fixed mold 1 through a bracket and bolts, and the piston rod extends into the fixed mold 1, and the extension direction is the same as the sliding direction of the sleeve frame 6.

[0040] Reference Figure 2 and Figure 3 The sleeve mold 5 is sleeved on the ends of the two inner molds 3 and is slidably connected to the inner molds 3. A connecting block 51 is also provided on the sleeve mold 5, and the connecting block 51 is fixedly connected to the end of the sleeve mold 5 away from the injection molded part. The connecting block 51 is located between the two inner molds 3. The piston rod in the cylinder is fixedly connected to the connecting block 51, so that the cylinder can drive the sleeve mold 5 to move through the connecting block 51.

[0041] Reference Figure 2 and Figure 3 The end of the sleeve mold 5 away from the driving member 4 extends out of the sleeve frame 6 to be sleeved on the end of the injection molded part. The end of the sleeve mold 5 extending out of the sleeve frame 6 also has a plurality of protrusions for molding, so that the end of the injection molded part is formed into a specific shape.

[0042] Reference Figure 2 and Figure 3 One end of the abutment frame 61 is clamped on the inner side wall of the sleeve frame 6, so that the abutment frame 61 can drive the sleeve frame 6 to slide together. The other end of the abutment frame 61 extends in the direction close to the connecting block 51, so that the other end of itself is located on the sliding path of the sleeve mold 5. A through slot is opened on the side wall of each abutment frame 61 for the corresponding inner mold 3 to pass through, so as to facilitate its own displacement.

[0043] Reference Figure 1 and Figure 2, two locking frames 7 are further provided on the side of the movable mold 2 close to the fixed mold 1, and the two locking frames 7 are fixedly connected to the movable mold 2. In other embodiments, a driving device for driving the locking frame 7 to slide relative to the movable mold 2 is further provided on the movable mold 2 to realize the separate driving of the locking frame 7.

[0044] Reference Figure 2 and Figure 3 Two locking grooves 8 are also provided on the outer wall of the sleeve frame 6 near the movable mold 2. The locking grooves 8 correspond to the locking frames 7 and are adapted to each other so that the locking frames 7 can be inserted into the locking grooves 8, thereby locking the sleeve frame 6. When the locking frames 7 are inserted into the locking grooves 8, the side walls of the locking frames 7 abut against the side walls of the sleeve mold 5 near the abutment frame 61, thereby reducing the probability of the sleeve mold 5 accidentally sliding away from the injection molded part by abutment.

[0045] The implementation principle of the push-pull rod housing injection mold in Example 1 of the present application is as follows: when the injection molded part is initially formed, the movable mold 2 is separated from the fixed mold 1, thereby driving the locking frame 7 to gradually separate from the locking groove 8. When the locking frame 7 is completely separated from the locking groove 8, the locking frame 7 cancels the locking of the sleeve mold 5 and the sleeve frame 6. Thereafter, the driving member 4 drives the sleeve mold 5 away from the injection molded part, so that the end of the injection molded part is exposed, and under the tension of its own material, it gradually opens a certain distance, so that the protrusion in the end of the injection molded part is separated from the protrusion molding groove 31 on the inner mold 3. When the injection molded part is completely formed, the driving member 4 drives the sleeve mold 5 away from the injection molded part again, and at this time, the sleeve mold 5 gradually abuts against the abutment frame 61, so that the sleeve mold 5 drives the sleeve frame 6 to move away from the injection molded part together, so that the inner mold 3 is gradually moved out of the injection molded part.

[0046] Embodiment 2: The difference between the second embodiment of the present application and the first embodiment is that: Figure 5 , Figure 6 and Figure 7 When the locking frame 7 is inserted into the locking groove 8, it does not abut against the side wall of the sleeve mold 5. Each abutting frame 61 is located at the lower side of the inner mold 3 and is slidably connected to the sleeve frame 6 through a slide rail, and the sliding direction is perpendicular to the sliding direction of the sleeve mold 5. Abutting grooves 511 are provided on the opposite side walls of the connecting block 51 for the corresponding abutting frames 61 to be inserted, so as to achieve the fixation between the connecting block 51 and the sleeve frame 6.

[0047] Reference Figure 6 and Figure 7Each abutting frame 61 is provided with a locking assembly 9, each locking assembly 9 includes a driving frame 91 and a linkage member 92, each driving frame 91 is located above the corresponding abutting frame 61, and is slidably connected to the inner wall of the sleeve frame 6 through a slide rail, and the sliding direction is the height direction of the sleeve frame 6. Each linkage member 92 includes two linkage frames 921, and the two linkage frames 921 are respectively located on opposite sides of the corresponding driving frame 91.

[0048] Reference Figure 7 and Figure 8 One end of each linkage frame 921 is rotationally connected to the corresponding driving frame 91 through a pin shaft, and the other end of each linkage frame 921 is rotationally connected to the corresponding abutting frame 61 through a pin shaft to realize transmission between the driving frame 91 and the abutting frame 61.

[0049] Reference Figure 7 and Figure 8 , each driving frame 91 is provided with an elastic member 93, and each elastic member 93 is located below the corresponding driving frame 91. In the embodiment of the present application, the elastic members 93 are configured as pressure springs, and each pressure spring is sleeved on the sleeve frame 6, and one end of each pressure spring abuts against the bottom end of the corresponding driving frame 91, and the other end abuts against the inner top wall of the sleeve frame 6, so that the driving frame 91 can be restored to the initial position by its own elastic force.

[0050] Reference Figure 7 and Figure 8 Each locking frame 7 is provided with an anti-slip mechanism 10, each anti-slip mechanism 10 includes an anti-slip frame 101 and an anti-slip assembly 102, each anti-slip assembly 102 includes a rotating frame 1021, a sleeve block 1022 and a driving member 1023, and each driving member 1023 includes a sliding frame 10231 and a driving frame 10232. In the embodiment of the present application, the number of the rotating frame 1021, the sleeve block 1022 and the driving frame 10232 on each locking frame 7 is set to two, and they are respectively located on opposite sides of the locking frame 7.

[0051] Reference Figure 7 and Figure 8 Each sliding frame 10231 is slidably connected to the corresponding locking frame 7, and the sliding direction is the height direction of the locking frame 7. Each driving frame 91 is located on the displacement path when the corresponding sliding frame 10231 moves together with the locking frame 7, so that the sliding frame 10231 can abut against the driving frame 91 and push the driving frame 91 to slide, so that the locking frame 7 passes through the sliding frame 10231 and abuts against the driving frame 91, and the abutting frame 61 passes through the driving frame 91 and abuts against the sliding frame 10231.

[0052] Reference Figure 7 and Figure 8In other embodiments, the locking frame 7 further extends a portion specifically for abutting the driving frame 91, so that the locking frame 7 directly abuts the driving frame 91. In other embodiments, the abutting frame 61 further extends a portion specifically for abutting the sliding frame 10231, so that the abutting frame 61 can directly abut the sliding frame 10231.

[0053] Reference Figure 5 , Figure 7 and Figure 8 In the initial state, that is, when the locking frame 7 is not inserted into the locking groove 8, the driving frame 91 is located on the side of its own sliding path away from the abutting frame 61, and the abutting frame 61 is not inserted into the abutting groove 511 on the connecting block 51. When the locking frame 7 is gradually inserted into the locking groove 8, the sliding frame 10231 gradually abuts against the driving frame 91, thereby driving the driving frame 91 to approach the abutting frame 61. At this time, the abutting frame 61, driven by the linkage frame 921, gradually approaches the connecting block 51, and is finally inserted into the abutting groove 511 on the connecting block 51, fixing the connecting block 51 and the sleeve mold 5.

[0054] Reference Figure 7 and Figure 8 , reset springs 103 are arranged on opposite sides of each locking frame 7, and each reset spring 103 is sleeved on the corresponding locking frame 7 and is located above the corresponding sliding frame 10231. One end of each reset spring 103 abuts against the top wall of the corresponding sliding frame 10231, and the other end abuts against the locking frame 7, so as to realize the reset of the sliding frame 10231.

[0055] Reference Figure 7 and Figure 8 One end of each rotating frame 1021 is located above the corresponding sliding frame 10231 and is rotatably connected to the corresponding locking frame 7 through a pin shaft, and the other end of each rotating frame 1021 is tilted downward. Each driving frame 10232 is sleeved on the corresponding rotating frame 1021 and is slidably connected to the corresponding rotating frame 1021. Each driving frame 10232 is rotatably connected to the corresponding sliding frame 10231 through a pin shaft.

[0056] Reference Figure 7 and Figure 8 Each set block 1022 is set on the bottom of the corresponding rotating frame 1021 and is slidably connected to the corresponding rotating frame 1021. Each set block 1022 is rotatably connected to the corresponding anti-slip frame 101 through a pin shaft, and each anti-slip frame 101 is slidably connected to the corresponding locking frame 7 through a slide rail, and the sliding direction is the same as the sliding direction of the set mold 5, and the set mold 5 is located on the displacement path of each anti-slip frame 101.

[0057] Reference Figure 5 , Figure 7 and Figure 8 In the initial state, the anti-slip frame 101 is located at one end of its own sliding path close to the sliding frame 10231, and the sliding frame 10231 is located at the bottom of the locking frame 7. When the locking frame 7 is inserted into the locking groove 8 and the sliding frame 10231 abuts against the driving frame 91, the sliding frame 10231 drives the driving frame 91 to slide. Thereafter, when the abutting frame 61 is inserted into the bottom of the abutting groove 511, the sliding frame 10231 remains stationary relative to the driving frame 91, and the locking frame 7 continues to slide, so that the sliding frame 10231 slides upward relative to the locking frame 7.

[0058] Reference Figure 7 and Figure 8 In this process, the position of the driving frame 10232 in the height direction of the locking frame 7 changes, so that the driving frame 10232 drives the rotating frame 1021 to rotate, so that the rotating frame 1021 drives the sleeve block 1022 to move, and the sleeve block 1022 slides relative to the rotating frame 1021. In this process, the anti-slip frame 101 slides under the drive of the sleeve block 1022, gradually approaches the sleeve mold 5, and finally abuts against the sleeve mold 5.

[0059] The implementation principle of the push-pull rod housing injection mold of the second embodiment of the present application is as follows: when the locking frame 7 is inserted into the locking groove 8 and the sliding frame 10231 abuts against the driving frame 91, the sliding frame 10231 drives the driving frame 91 to slide. Thereafter, when the abutting frame 61 is inserted into the bottom of the abutting groove 511, the sliding frame 10231 remains stationary relative to the driving frame 91, and the locking frame 7 continues to slide, so that the sliding frame 10231 slides upward relative to the locking frame 7.

[0060] During this process, the position of the driving frame 10232 in the height direction of the locking frame 7 changes, so that the driving frame 10232 drives the rotating frame 1021 to rotate, so that the rotating frame 1021 drives the sleeve block 1022 to move, and the sleeve block 1022 slides relative to the rotating frame 1021. During this process, the anti-slip frame 101 slides under the drive of the sleeve block 1022, gradually approaches the sleeve mold 5, and finally abuts against the sleeve mold 5.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
