Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a first-time product fixing structure of a two-color light distribution mirror for a headlight. Background Art

[0002] Currently, molds for dual-color headlight mirrors are primarily designed using a flip-up design, placing the gate on the ejection side. After the first part is molded, it needs to be retained on the rotating side. Because the first part lacks ribs or other structures, it cannot be stably fixed on the rotating side. This makes the mold prone to falling during rotation, making it unstable. Therefore, a new structure for securing the first part of the dual-color headlight mirrors has been proposed. Utility Model Content

[0003] (1) Technical problems solved

[0004] Aiming at the problem of products falling off when the mold rotates, the utility model provides a first product fixing structure of a two-color light distribution mirror for a headlight, which solves the problems raised in the above background technology.

[0005] (2) Technical solution

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a first product fixing structure for a two-color lens for a headlight, comprising a mold, an insert connected to the mold, a formed product provided in the insert, a fixing component capable of being displaced along the interior of the insert and capable of limiting and fixing the product, the fixing components being arranged in sequence along one side of the product; the fixing component comprising a slider insert capable of being moved along the interior of the insert, the end of the slider insert being provided with a contact plate capable of contacting the product.

[0007] Furthermore, the mold is provided with a slider seat that can be connected to the slider insert, and the slider seat is displaced along the slide groove inside the mold. The slide groove inside the mold is provided with a connecting rod that can push the slider seat to displace.

[0008] Furthermore, a cylinder body is provided on the outside of the mold, and the cylinder body is movable. A piston is provided in the cylinder body and can be connected to a connecting rod and can drive the connecting rod to move. A travel switch bracket connected to the connecting rod is provided in the mold.

[0009] Furthermore, the output end of the piston is provided with a guide block that can guide the movement of the connecting rod, the connecting rod is provided with a conflicting piece that can conflict with the guide block, and the connecting rod is provided with an anti-loosening gasket that can be installed on the connecting rod.

[0010] Furthermore, the distance between the guide block and the abutment piece is 2.3 mm.

[0011] Furthermore, the travel switch bracket is installed in the connecting rod through a long bolt, and the anti-loosening gasket is installed in the connecting rod through a short bolt.

[0012] Furthermore, the fixing components are arranged in sequence along the ends of the periphery of the product.

[0013] Furthermore, the end of the outer periphery of the product can be provided with a latch adapted to the abutment plate.

[0014] Furthermore, the number of card slots in the product is five.

[0015] Furthermore, the mold is provided with two products arranged opposite to each other, and the mold is provided with a fixing component that can be opposite to the two products.

[0016] This solution adds 5 locking positions to the product, which enables the cylinder body to drive the inserts and other structures to press the product, thus ensuring that the product will not move in the mold.

[0017] As with conventional two-shot molds, after the first molding, the part remains on the rotating side. The mold turntable rotates 180 degrees, carrying the part to the second molding location. In this structural improvement, because the surface of the headlight part is smooth, the clamping force is primarily concentrated on the fixed mold side. To keep the part on the rotating side, a hydraulic cylinder and slider inserts are installed around the part to hold it down, ensuring a stable first molding position.

[0018] When making this product, two operations are required. The first time, the middle part of the product (i.e., the movable side mold) is produced. After the production is completed, the cylinder body can drive the insert and other structures to press the middle part of the product. After that, when it is rotated to adjust its position, it is prevented from moving. After the second product is made on the first product (i.e., the structure is continued to be added around the first product, at this time, the cylinder body can be pushed back 2.3mm, and then the second product is produced in the mold. Then, the mold is opened to eject the product.

[0019] This solution has certain limitations: it uses a large number of travel switches, the molding machine must have a corresponding control interface, and there are high requirements for adjusting the travel and action sequence.

[0020] Compared with the existing technology, this is a first product fixing structure for a two-color lens for a headlight. By sequentially arranging oil cylinder bodies around the product to drive the slider insert to move, the slider insert can make the contact plate contact with the latch in the product during movement, thereby stably pressing the product at the position of the rotating side, thereby improving the practicality of the equipment.
