Description

Technical Field

[0001] This utility model belongs to the field of demolding structures, specifically relating to a demolding structure for automotive headlight trim strips. Background Technology

[0002] As a crucial lighting component for vehicles, automotive headlights require exterior trim designs that ensure both excellent illumination and aesthetic appeal, while also prioritizing safety. During headlight production, the trim is typically molded using injection molding. However, with the increasing diversity and complexity of vehicle designs, the trim features more intricate details, such as intricate structures like undercuts, posing challenges during demolding. Traditional demolding methods often fail to effectively handle trims with undercut features, leading to decreased product quality or reduced production efficiency. Therefore, a new demolding structure for automotive headlight trim is needed to address these issues. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a demolding structure for automotive headlight trim strips, which addresses the issue mentioned in the background art that existing automotive headlight trim strips on the market are difficult to demold due to their complex structure and inverted design.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A demolding structure for automotive headlight trim strips, comprising:

[0006] The base plate, first top plate, second top plate, fixed template, moving template, and internal mold core are set in sequence.

[0007] The base plate is provided with a plurality of first fixing grooves, a first slide block is installed in the first fixing groove, a first inclined push rod is slidably connected on the first slide block, and a first waist-shaped hole is provided on the first top plate to restrict the movement of the first inclined push rod.

[0008] The second top plate is provided with a plurality of second fixing grooves, and a second slide block is installed in the second fixing groove. A second inclined push rod is slidably connected to the second slide block.

[0009] As a further improvement to this utility model, four sets of driving cylinders are provided on the side of the fixed template, and the output end of the driving cylinder is fixedly connected to the first top plate and the second top plate.

[0010] As a further improvement to this utility model, the first slide block is symmetrically arranged on the base plate, and the inclination direction of the opposite first inclined push rod is opposite.

[0011] As a further improvement to this utility model, the second slide block is symmetrically arranged on the first top plate, and the second inclined push rod has a different inclination direction from the first inclined push rod.

[0012] As a further improvement to this utility model, it also includes a plurality of ejector pins, which are disposed between the two sets of opposing first inclined ejector pins.

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

[0014] This invention improves demolding efficiency by using a number of inclined ejector rods set on the base plate, the first top plate, and the second top plate. The lifting of the top plate causes the inclined ejector rods to move, thereby demolding the undercut part of the product. Attached Figure Description

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention provides the following embodiments:

[0024] A demolding structure for automotive headlight trim strips, comprising:

[0025] The following components are arranged in sequence: base plate 1, first top plate 2, second top plate 3, fixed template 4, moving template 5, and internal mold core.

[0026] The base plate 1 is provided with a plurality of first fixing grooves 11, and a first slide block 12 is installed in the first fixing groove 11. A first inclined push rod 13 is slidably connected to the first slide block 12. A first waist-shaped hole 21 is provided on the first top plate 2 to restrict the movement of the first inclined push rod 13. The first slide blocks 12 are symmetrically arranged on the base plate 1, and the inclination direction of the corresponding first inclined push rods 13 is opposite.

[0027] The second top plate 3 is provided with a plurality of second fixing grooves 32, and a second slide block 33 is installed in the second fixing groove 32. A second inclined push rod 34 is slidably connected to the second slide block 33. The second slide block 33 is symmetrically arranged on the first top plate 2, and the second inclined push rod 34 is inclined in a different direction from the first inclined push rod 13.

[0028] This utility model improves demolding efficiency by using a number of inclined ejector rods set on the base plate 1, the first top plate 2, and the second top plate 3. The lifting of the top plate causes the inclined ejector rods to move, thereby demolding the undercut part of the product.

[0029] The fixed template 4 is provided with four sets of driving cylinders 6 on its side. The output end of the driving cylinder 6 is fixedly connected to the first top plate 2 and the second top plate 3. The driving cylinder 6 drives the first top plate 2 and the second top plate 3 to rise, thereby driving the first inclined ejector rod 13 and the second inclined ejector rod 34 to move and causing the undercut part to be demolded.

[0030] It also includes a number of ejector pins 7, which are located between the two sets of opposing first inclined ejector pins 13. The ejector pins 7 drive the product to be demolded at the same time as the undercut part of the product is demolded.
