Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to a mold for an automobile hood sealing strip. Background Art

[0002] A sealing strip is correspondingly installed in the sealing structure of an automobile hood, which plays a role of buffering and sealing during the opening and closing process. It must have strong tensile strength, good elasticity, and also relatively good heat resistance and aging resistance. In order to ensure the fastening of the rubber strip and the profile, the cross-sectional structure size of the rubber strip must match the profile. Generally, different harder materials are formed on the soft rubber strip to form a spliced sealing strip for use. After the spliced sealing strip is formed, the formed part of the sealing strip has a complex structure and it is difficult to take out the sealing strip. Summary of the Invention

[0003] In view of this, the purpose of the utility model is to overcome the deficiencies in the prior art and provide a mold for an automobile hood sealing strip.

On the left and right sides of the upper end of the displacement plate 5.1, inclined holes are symmetrically opened. Slide columns 5.2 are slidably matched at the inclined holes. The lower ends of the slide columns 5.2 are connected with a connecting bar 5.3 that is slidably matched with the lower mold 1 in the left and right directions. On the side of the connecting bar 5.3 away from the medium-sized block 2, a push rod 5.4 is arranged. The lower end of the side block 3 is connected with a flipping block 5.5 that is flipped by the push rod 5.4.

[0015] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0016] Refer to Figures 1 to 4, the utility model provides an automobile hood sealing strip mold, which comprises an upper mold and a lower mold 1. On the left and right sides of the upper end of the lower mold 1, medium-sized blocks 2 are symmetrically arranged. On the left and right sides of the medium-sized blocks 2, edge-shaped blocks 3 rotatable on the lower mold 1 are symmetrically arranged. On the front and back sides of the lower mold 1, L-shaped fixing blocks 6 are symmetrically installed. The edge-shaped blocks 3 are rotatably arranged between the two fixing blocks 6. A lower mold cavity is formed between the medium-sized blocks 2 and the edge-shaped blocks 3. The part of the insert sealing strip inserted into the edge-shaped block of the lower mold cavity is closed-molded and cast to form a spliced sealing strip. On the rear side of the lower mold 1, a cylinder 4 is longitudinally arranged. The piston rod of the cylinder 4 is connected with a flipping assembly 5 used to drive the edge-shaped blocks 3 to flip and symmetrically arranged left and right. The part of the insert sealing strip inserted into the edge-shaped block of the lower mold cavity is closed-molded and cast to form a spliced sealing strip. The cylinder drives the edge-shaped blocks and the spliced sealing strip to flip to the side away from the medium-sized block through the flipping assembly, so that the spliced sealing strip is separated from the medium-sized block, which is convenient for taking out.

[0017] Refer to Figure 3 , Figure 4 , the flipping assembly 5 comprises a displacement plate 5.1 slidably fitted to move back and forth on the lower mold 1. On the left and right sides of the upper end of the displacement plate 5.1, inclined holes are symmetrically opened. Slide columns 5.2 are slidably fitted at the inclined holes. The lower ends of the slide columns 5.2 are connected with a connecting strip 5.3 slidably fitted to move left and right on the lower mold 1. On the side of the connecting strip 5.3 away from the medium-sized block 2, a push rod 5.4 is arranged. The lower end of the edge-shaped block 3 is connected with a flipping block 5.5 flipped by the push rod 5.4. The cylinder drives the displacement plate to move backward. The inclined holes of the displacement plate drive the two side connecting strips to move horizontally to one side of the displacement plate through the slide columns. The push rods on the connecting strips push the flipping block to the side of the displacement plate, so that the flipping block and the edge-shaped block rotate outward around the rotation point of the fixing block, which is convenient for peeling off the spliced sealing strip. Then the displacement plate moves forward and resets. The inclined holes of the displacement plate drive the connecting strip and the push rod to move horizontally to the side away from the displacement plate through the slide columns. The push rod pushes the flipping block to the side away from the displacement plate, so that the flipping block and the edge-shaped block rotate in the reverse direction and reset.

[0018] On the side of the connecting strip 5.3 away from the medium-sized block 2, a convex part extends upward. The push rod 5.4 is longitudinally connected to the upper end of the convex part.

[0019] The flipping block 5.5 is in a concave shape. The push rod 5.4 is longitudinally arranged in the lower groove of the flipping block 5.5. The lower groove can limit the push rod, so as to limit the slide column on the connecting strip. The push rod moves in the direction of the displacement plate and pushes the flipping block to flip. The push rod moves in the direction away from the displacement plate and pushes the flipping block to rotate in the reverse direction and reset.

[0020] At the end of the piston rod of the cylinder 4, a push-pull rod is arranged. On the upper ends of the two displacement plates 5.1, a long strip 8 is horizontally connected. At the rear end of the long strip 8, a T-shaped block 7 with a T-shaped groove is connected. The push-pull rod pulls and pushes the T-shaped block 7 through the T-shaped groove. The cylinder pulls and pushes the T-shaped block through the push-pull rod, and the T-shaped block then pulls and pushes the long strip, so as to pull and push the displacement plate, which is convenient for installation and avoids hard connection.

[0021] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
