Description

Technical Field

[0001] This utility model belongs to the field of sealing strip processing technology, and specifically relates to an automatic top strip insertion clamp device. Background Technology

[0002] With the rapid development of my country's automotive industry, automobile production scale is expanding, and the demand for sealing strips, as an integral part of automobiles, is also increasing. A complete sealing strip requires two production processes: cutting and injection molding, to form a finished product. To meet the demand for large-volume production, automated production lines integrating cutting and injection molding are being established to improve production efficiency. Previously, when inserting the top-mounted sealing strip in the injection molding process, personnel needed to pre-assemble the strip on the mold before inserting it into the mold cavity using an insertion mechanism on the mold. Furthermore, since the two ends of the same sealing strip needed to be joined on two different molds, this required two pre-assembly operations. However, because automated production lines require robots to handle multiple types of sealing strips, the pre-assembly method on the mold is no longer suitable for current production needs, as it requires versatility and efficient handling of various sealing strips.

[0003] Therefore, the existing insert technology still needs to be improved. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide an automatic top bar insertion clamping device, which has a simple structure, reasonable design, is easy to produce, has a high degree of automation, and reduces manual labor. By optimizing the structure of the mold, and through the cooperation of the insertion clamping device and the insertion power mechanism, the top bar sealing strip is inserted into the mold cavity with an arc, so as to realize the automatic insertion.

[0005] Technical solution: To achieve the above objectives, this utility model provides an automatic top bar insertion clamping device, comprising:

[0006] The lower mold has a lower mold cavity.

[0007] A drive mechanism for moving the insert strip, the drive mechanism being connected to the lower mold;

[0008] An insert strip positioning fixture is mounted on the lower mold and the two are movably connected; the output end of the insert strip power mechanism can drive the insert strip positioning fixture to move. This utility model discloses an automatic top strip inserting fixture device. By optimizing the mold structure and cooperating with the insert strip positioning fixture and the insert strip power mechanism, the top strip sealing strip is inserted into the mold cavity with an arc shape, achieving automated insertion. This effectively solves the current problem of difficult strip insertion. Furthermore, since the sealing strip is installed on the insert strip sheet metal fixture in a single operation, the traditional step of manually installing the strip again when connecting the other end to the mold is eliminated. When the other end of the top strip sealing strip needs to be connected to the mold, the robot simply connects the other end of the insert strip sheet metal fixture to another mold, thereby reducing the need for multiple manual strip installations and improving production efficiency.

[0009] The lower mold includes a lower template, which has an extension section on one side of the insert power mechanism. The extension section has a sliding groove, and a sliding block is located within the through hole. The sliding block is connected to the insert positioning fixture via a set of positioning pins. The end of the sliding block is connected to the insert power mechanism via a power connecting rotating pin and a power connecting block. When the power connecting rotating pin and the power connecting block are combined, the insert power mechanism can rotate and push the sliding block on the power connecting rotating pin, which in turn drives the power connecting block, thus enabling the sliding block to slide with an arc, becoming a curved insert.

[0010] Furthermore, a set of limiting blocks are provided above the sliding block. The limiting blocks can limit the upper part of the sliding block and improve its sliding stability.

[0011] Furthermore, the lower mold extension section is provided with limiting mechanisms on both sides of the sliding groove.

[0012] Preferably, the limiting mechanism includes a first limiting block and a second limiting block, which are disposed opposite to each other on both sides of the sliding groove.

[0013] Furthermore, the insert positioning fixture includes a fixture base plate, a strip assembly sheet metal, a set of support blocks, and a set of elbow clamp positioning components. The strip assembly sheet metal is mounted on the fixture base plate, and the support blocks are also mounted on the fixture base plate, positioned opposite each other on both sides of the strip assembly sheet metal. The elbow clamp positioning components are mounted on one side of the fixture base plate via mounting seats, and the positioning end of the elbow clamp positioning components is equipped with a sealing strip pressure block. The insert positioning fixture can position the sealing strip and prevent it from shifting during the insertion process.

[0014] Preferably, the lower mold is provided with insert plates and slider assemblies on both sides of the mold cavity. The insert plates and slider assemblies, when entering the mold cavity, guide the sealing strip into the receiving mold cavity through the cooperation of the guides on the insert plates, the guides on the slider assemblies, and the guides in the lower mold cavity.

[0015] More preferably, the insert power mechanism includes an insert drive mechanism, the output end of which is connected to the power connection rotating column via a connector.

[0016] Furthermore, the sliding groove adopts a T-shaped arc sliding groove, and the sliding block adopts a T-shaped arc positioning sliding block, which cooperates with the sliding groove. The T-shaped arc sliding groove and the T-shaped arc positioning sliding block can control the insertion path of the sealing strip, allowing it to better meet the processing needs.

[0017] In addition, a transport bracket is provided on one side of the insert positioning fixture, and the transport bracket is connected to the robot transport chuck. The connection between the transport bracket and the robot transport chuck facilitates the robot's handling and control of the insert.

[0018] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0019] 1. The automatic top strip insertion clamping device of this utility model optimizes the structure of the mold and, through the cooperation of the insertion positioning clamp and the insertion power mechanism, inserts the top strip sealing strip with an arc into the mold cavity, realizing automated insertion. This effectively solves the current problem of difficult insertion. Furthermore, since the sealing strip is installed on the insertion sheet metal clamp in one go, the original step of manually installing the strip again when connecting the mold at the other end can be eliminated. The robot only needs to connect the other end of the insertion sheet metal clamp to another mold, thereby reducing the need for multiple manual strip installations and improving production efficiency.

[0020] 2. The installation of the strip positioning fixture can position the sealing strip and prevent it from shifting during the insertion process.

[0021] 3. The setting of the insert plate and slider assembly: When entering the mold cavity, the sealing strip is guided into the receiving mold cavity by the cooperation of the guide on the insert plate, the guide of the slider assembly and the guide of the lower mold cavity.

[0022] 4. During the insertion of the sealing strip, the sliding block and the sliding groove limit the arc of the sealing strip, and the forward distance of the sealing strip continuously changes the insertion angle. This is to meet the arc requirements of the mold cavity caused by the arc of the molded product itself and to solve the problem of difficult insertion of the arc-shaped strip.

Detailed Implementation

[0031] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. Example

[0032] like Figures 1 to 6 An automatic insert clamping device for top strips is shown, comprising: a lower mold 11, an insert power mechanism 12 for driving movement, and an insert positioning clamp 13. The lower mold 11 is provided with a lower mold cavity. The insert power mechanism 12 is connected to the lower mold 11. The insert positioning clamp 13 is disposed on the lower mold 11, and the two are movably connected. The output end of the insert power mechanism 12 can drive the insert positioning clamp 13 to move.

[0033] The lower mold 11 includes a lower template. The lower template has a lower mold extension section 111 on one side of the insert power mechanism 12. The lower mold extension section 111 has a sliding groove 112, and a sliding block 113 is located within the through hole. The sliding block 113 is connected to the insert positioning fixture 13 via a set of positioning pins 114. The end of the sliding block 113 is connected to the insert power mechanism 12 via a power connecting rotating pin 115 and a power connecting block 123. After the power connecting rotating pin 115 and the power connecting block 123 are combined, the insert power mechanism can rotate and push the sliding block on the power connecting rotating pin. The power connecting rotating pin then drives the power connecting block, thus enabling the sliding block to slide with an arc, thereby becoming an arc-shaped insert.

[0034] A set of limiting blocks 116 are provided above the sliding block 113.

[0035] like Figure 3 The lower mold extension section 111 shown is provided with limiting mechanisms 117 on both sides of the sliding groove 112. The limiting mechanism 117 includes a first limiting block 1171 and a second limiting block 1172, which are positioned opposite each other on both sides of the sliding groove 112. It should be noted that the first limiting block 1171 is an L-shaped limiting block, and the second limiting block 1172 is an L-shaped support strip limiting block. These can be adjusted according to actual production needs to meet those requirements.

[0036] like Figure 1 , Figure 3 , Figure 6 The insert positioning fixture 13 shown includes a fixture base plate 131, a strip mounting sheet metal 132, a set of support blocks 133, and a set of elbow clamp positioning components 134. The strip mounting sheet metal 132 is disposed on the fixture base plate 131, and the support blocks 133 are disposed on the fixture base plate 131 and are disposed opposite to each other on both sides of the strip mounting sheet metal 132. The elbow clamp positioning components 134 are mounted on one side of the fixture base plate 131 through a mounting seat, and the positioning end of the elbow clamp positioning components 134 is provided with a sealing strip pressure block 135.

[0037] The lower mold 11 is provided with insert plates 14 and slider assemblies 15 on both sides of the mold cavity.

[0038] like Figures 1 to 4 The insert power mechanism 12 shown includes an insert drive mechanism 121, the output end of which is connected to the power connection rotating column 115 via a connector 122. It should be noted that the insert drive mechanism 121 uses a servo motor, but other drive mechanisms can also be used as needed to meet production requirements.

[0039] like Figure 3The sliding groove 112 shown is a T-shaped arc sliding groove, and the sliding block 113 is a T-shaped arc positioning sliding block, which cooperates with the sliding groove 112. During the insertion of the sealing strip, under the arc limitation of the sliding block 113 and the sliding groove 112, the forward distance of the sealing strip continuously changes the insertion angle, thereby meeting the arc requirement of the mold cavity caused by the arc of the molded product itself and solving the problem of difficulty in inserting the arc-shaped strip.

[0040] Example 2

[0041] The automatic top bar insert clamping device described in this embodiment has the same structure as that in Embodiment 1.

[0042] The insert positioning clamp 13 is provided with a transport bracket 16 on one side, and the transport bracket 16 is connected to the robot transport chuck 17.

[0043] The working principle of the automatic top strip insertion clamp device described in this embodiment is as follows: First, the sealing strip to be processed is installed on the insertion positioning clamp 13, and the sealing strip pressing block 135 on the elbow clamp positioning component 134 presses the sealing strip onto the strip mounting sheet metal 132.

[0044] The robot (not shown in the figure) transports the insert positioning fixture 13 with the sealing strip installed to the lower mold 1. At the same time, the positioning hole of the fixture base plate 131 in the insert positioning fixture 13 docks with the positioning post 114 on the T-shaped arc positioning sliding block 113 in the lower mold 1, and the top of the second limiting block 1172 lifts the lip of the sealing strip on the insert side to facilitate the subsequent insertion of the lip.

[0045] After docking is completed, the insert drive mechanism 121 in the insert power mechanism 12 drives the power connection block 123 and the power connection rotating column 115 to drive the sliding block 113 to move forward along the sliding groove 112. At the same time, the sliding block 113 drives the insert positioning fixture 13 to move forward along the arc of the T-shaped arc sliding groove of the sliding groove 112 and enter the first limit block 1171 and the second limit block 1172 until it stops at the mold connection position.

[0046] During operation, the insert positioning fixture 13 moves forward with the sealing strip into the mold cavity. When entering the mold cavity, the sealing strip is guided into the mold cavity by the guide on the insert plate 14, the guide on the slider assembly 15, and the guide of the lower mold cavity. During the insertion process, under the curvature limit of the sliding block 113 and the sliding groove 112, the sealing strip will continuously change the insertion angle as it moves forward, so as to meet the curvature requirement of the mold cavity caused by the curvature of the molded product itself and solve the problem of difficult insertion of the curved strip.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
