[0036] During the production and processing of automobiles, the corners of the door frames will be sealed, which requires the lower door sealing strip to be realized, and the production of the lower door sealing strip requires the use of corner molds.

[0037] At present, the injection devices of domestic automobile door corner sealing machines generally do not have a mechanical anti-fall function. When the injection device is raised to the highest position, a hydraulic valve is used to prevent the injection device from falling. However, the hydraulic device cannot completely prevent the injection device from falling. There is a risk of a safety accident to the operator due to failure of the hydraulic device and the injection device falling.

[0038] In order to solve the above problems, the utility model proposes an injection device for an automobile door corner sealing machine, which aims to ensure the safety of the injection device and prevent the injection device from falling when it is lifted or moved. Figure 1 to Figure 2 The present invention is a schematic structural diagram of an embodiment of an injection device for an automobile door corner sealing machine provided by the present invention.

[0039] Please refer to Figure 1 to Figure 2 The utility model proposes an injection device 1000 for an automobile door sealing angle machine, comprising a barrel 1, an injection seat 2, a guide column 3 and an anti-drop mechanism 4, wherein the barrel 1 injects rubber into the mold; the barrel 1 is mounted on the injection seat 2; the injection seat 2 is sleeved on the guide column 3 and can move up and down along the guide column 3; the anti-drop mechanism 4 is mounted on the injection seat 2, and the anti-drop mechanism 4 includes a movable clamping portion 41; a matching portion 31 is provided on the guide column 3, and when the injection seat 2 moves upward along the guide column 3, the clamping portion 41 of the anti-drop mechanism 4 engages with the matching portion 31 to limit the injection seat 2 from moving downward.

[0040] In the technical solution of the utility model, an injection device 1000 for an automobile door corner sealing machine is proposed. When the injection seat 2 moves to the top of the guide column 3, the clamping part 41 is movably matched with the matching part 31, so as to restrict the injection seat 2, and prevent the injection seat 2 from falling from the top of the guide column 3 and damaging the automobile door corner sealing machine or causing harm to the operator, thereby avoiding the potential safety hazards that may be caused when the injection seat 2 of the automobile door corner sealing machine rises, and ensuring the safety during injection.

[0041] In an optional embodiment, to achieve the matching between the clamping portion 41 and the matching portion 31, the clamping portion 41 is a latch and the matching portion 31 is a clamping hole; or the clamping portion 41 is a stopper and the matching portion 31 is a limit plate. Figure 1 , the latch surface is set on one side of the guide column 3 and is connected to the output end of the driving member 43. The guide column 3 is formed with a clamping hole facing the latch. When the injection seat 2 is moved to the upper position of the injection seat 2 under the drive of the hydraulic system, the latch moves close to the clamping hole and is finally inserted into the clamping hole to realize the matching positioning of the latch. In this way, under the action of the latch and the clamping hole, the injection seat 2 is restricted and cannot move downward, which can prevent the injection seat 2 from falling and injuring the operator or machine below when it is lifted, thereby ensuring production safety. Optionally, the anti-drop mechanism 4 can be set at one end of the guide column 3, or at both ends of the guide column 3. It can be installed and set according to actual needs, and no specific limitation is made here.

[0042] In another optional embodiment, the clamping portion 41 is a stopper, and the matching portion 31 is a limit plate. Optionally, the matching portion 31 can be a limit plate provided on the guide column 3. When the injection seat 2 moves to the upper limit position, the stopper approaches the limit plate and moves to overlap the part of the structure above the limit plate, thereby realizing the overlap limit of the stopper and the limit plate, achieving the effect of limiting the fall of the injection seat 2, and ensuring the safety and stability of the injection seat 2.

[0043] In an optional embodiment, in order to further ensure the stable cooperation between the latch and the clamping hole, two clamping holes are provided on the guide column 3, and the two clamping holes are arranged in parallel in the extension direction of the guide column 3. By providing the two clamping holes at different heights on the guide column 3, an additional layer of protection is added for the latch and the clamping hole, so that even if the latch and the uppermost clamping hole are offset when docking and fail to cooperate, since the latch is still subjected to a thrust at this time, when the injection seat 2 falls to the position of the clamping hole below due to its own gravity, the latch is inserted into the clamping hole below to realize the anti-drop state of the injection seat 2, thereby ensuring that the latch and the clamping hole can be stably cooperated.

[0044] In an optional embodiment, in order to facilitate the installation and fixation of the driving member 43, the anti-drop mechanism 4 also includes a mounting seat 42 and a driving member 43, the mounting seat 42 is connected to the side wall of the injection seat 2, and the driving member 43 is installed on the mounting seat 42. Please refer to Figure 1 and Figure 2The mounting seat 42 is installed on one side of the injection seat 2, and the driving member 43 is connected to the side of the mounting seat 42 facing away from the injection seat 2. The mounting seat 42 is formed with a through hole corresponding to the clamping portion 41, and the clamping portion 41 passes through the through hole on the mounting seat 42 and is connected to the driving member 43. In this way, the through hole on the mounting seat 42 can also guide the clamping portion 41 when it moves back and forth left and right under the drive of the driving member 43, so as to prevent the clamping portion 41 from deviating downward when moving left and right. The driving member 43 provides power to the clamping portion 41 to cooperate with the matching portion 31 to prevent the injection seat 2 from falling. In this embodiment, the driving member 43 is a driving cylinder. Of course, in other embodiments, the driving member 43 can also be a driving element such as a linear motor, which is not specifically limited here.

[0045] In an optional embodiment, in order to facilitate the lifting and moving of the mounting seat 42, the automobile door corner sealing machine injection device 1000 further includes a slide plate 5, the slide plate 5 is vertically connected to the machine platform of the automobile door corner sealing machine, and the mounting seat 42 is slidably connected to the slide plate 5. Please refer to Figure 1 and Figure 2 The slide plate 5 is fixedly connected to the machine platform of the automobile door corner sealing machine, the mounting seat 42 is sleeved on the slide plate 5 and connected to one side of the injection seat 2, and the slide plate 5 can play a guiding role when the mounting seat 42 moves up and down, thereby ensuring the stability of the sliding and lifting of the mounting seat 42, thereby indirectly ensuring the accuracy of the movement and cooperation between the driving member 43 and the clamping part 41.

[0046] In an optional embodiment, in order to further ensure the safety of the injection device 1000 of the automobile door corner sealing machine, the injection device 1000 of the automobile door corner sealing machine further comprises a movable door 6, which is vertically connected to the machine platform of the automobile door corner sealing machine and is located on one side of the injection seat 2. The movable door 6 can be rotated relative to the injection seat 2 in the vertical direction to realize opening and closing. Please refer to Figure 2 In order to prevent the operator from putting his hand into the working area and causing safety hazards when the injection mechanism 1 of the automobile door corner sealing machine is running, a movable door 6 can be provided on one side of the injection mechanism 1 to prevent the operator from operating incorrectly. In this embodiment, the movable door 6 is provided on one side of the injection mechanism 1 and can be rotated relative to the injection mechanism 1 to realize the rotation and opening and closing of the movable door 6. The automobile door corner sealing machine is started after the movable door 6 is closed to avoid the safety hazard of the operator entering the working area when the automobile door corner sealing machine is working. In addition, the movable door 6 can also serve as a safety protection barrier. Even if the components above the injection mechanism 1 fall, the movable door 6 can block them to avoid injuring the operator.

[0047] In an optional embodiment, in order to further improve the safety protection effect of the movable door 6, the automobile door sealing angle machine injection device 1000 also includes a movable door limiting mechanism 7, and the movable door limiting mechanism 7 includes a first limiting portion 71 and a second limiting portion 72. The first limiting portion 71 is connected to the side wall of the mounting seat 42, and the second limiting portion 72 is connected to the movable door 6. The first limiting portion 71 cooperates with the second limiting portion 72 to limit the opening and closing of the movable door 6. In order to prevent the operator from accidentally opening the movable door 6 to enter the working area when the injection mechanism 1 is running, the first limiting portion 71 and the second limiting portion 72 are respectively provided on the mounting seat 42 and the movable door 6. When the injection seat 2 has not moved to the upper limit position, the first limiting portion 71 and the second limiting portion 72 cooperate to limit the opening of the movable door 6. In this way, even if the operator accidentally wants to open the movable door 6, the movable door 6 cannot be opened due to the limitation of the movable door limiting mechanism 7, thereby further ensuring the reliability of the injection device 1000 of the automobile door sealing angle machine.

[0048] In an optional embodiment, in order to achieve the cooperation and limitation of the first limiting portion 71 and the second limiting portion 72, the first limiting portion 71 and the second limiting portion 72 are hook plate structures arranged opposite to each other, and the injection seat 2 is lifted and slid relative to the guide column 3 to achieve the overlap of the first limiting portion 71 and the second limiting portion 72. Please refer to Figure 2 , the first limiting part 71 and the second limiting part 72 are bent toward each other to form a bending part. When the injection seat 2 has not moved to the upper limit position, the bending parts of the first limiting part 71 and the second limiting part 72 are in a mutually matched state, and the movable door 6 cannot be opened due to the action of the movable door limiting mechanism 7. When the injection seat 2 moves to the upper limit position, the clamping part 41 and the matching part 31 cooperate to limit to reach the anti-drop state of the injection seat 2. At this time, the first limiting part 71 and the second limiting part 72 are in a staggered state in the vertical direction and are out of cooperation, and the movable door 6 can be opened to facilitate the operator to operate. In other words, during the period when the injection seat 2 moves from the lower limit position to the upper limit position, the movable door 6 is restricted from opening by the movable door limiting mechanism 7 to ensure the safety of the operator. When the injection seat 2 moves to the upper limit position, the injection seat 2 is in an anti-drop state by the anti-drop mechanism 4, so that the operator can open the movable door 6 for operation. By combining the anti-drop mechanism 4 and the movable door limiting mechanism 7, the safety of the operator is guaranteed when the injection seat 2 is raised or lowered.

[0049] In another optional embodiment, the first position-limiting portion 71 is provided with a first magnetic member, the second position-limiting portion 72 is provided with a second magnetic member, and the first magnetic member and the second magnetic member are magnetically matched. Optionally, the first position-limiting portion 71 and the second position-limiting portion 72 can also be matched and disengaged by a magnetic structure. When the injection seat 2 has not yet moved to the upper limit, the first position-limiting portion 71 and the second position-limiting portion 72 are matched by magnetic matching of the first magnetic member and the second magnetic member. When the injection seat 2 moves to the top, the first magnetic member and the second magnetic member are disengaged to open the movable door 6. Optionally, the first magnetic member and the second magnetic member can be magnets with magnetism themselves, or can be electromagnets, which are not specifically limited here.

[0050] The utility model also proposes a car door corner sealing machine, which includes a car door corner sealing machine injection device 1000 and a machine platform, wherein the car door corner sealing machine injection device 1000 is arranged on the machine platform, the movable door 6 is located on one side of the car door corner sealing machine injection device 1000 and is rotatably connected to the machine platform, and a movable door 6 limiting structure is arranged at the free end of the movable door 6. The specific structure of the car door corner sealing machine injection device 1000 refers to the above embodiment. Since the car door corner sealing machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0051] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
