Description

Technical Field

[0001] This application relates to the field of decorative insert sheet fixing technology, specifically to an in-mold surface decorative insert rotating fixture. Background Technology

[0002] In-mold decorative inserts are decorative components used in the plastic injection molding process. They are typically embedded in the mold and become part of the final product. Their main function is to create a decorative effect directly within the mold, avoiding secondary processing such as spraying or film application. This improves production efficiency, reduces costs, and enhances the product's aesthetics. In-mold decorative inserts are widely used in industries such as automotive, home appliances, and electronic equipment, especially in products that require a refined appearance, smooth surface, and durability. Their design and manufacturing process involves precise mold technology and high-quality material selection to ensure the durability of the decorative effect and the overall quality of the product.

[0003] In practice, traditional sheet insert fixing methods have drawbacks such as low precision, complex operation, limited mold design, and difficulty in meeting special needs. Because the sheet is fixed by horizontal movement of the slider, it is easy to cause inaccurate positioning. There is also a lack of clear visual feedback during operation, which increases the difficulty of operation. In addition, the traditional device structure is bulky and occupies a lot of space, resulting in increased mold size and cost. At the same time, for some special process requirements and complex mold shapes, traditional designs are difficult to provide stable and accurate sheet positioning, which affects production efficiency and product quality. Summary of the Invention

[0004] Therefore, this application provides an in-mold surface decorative insert rotation fixture to solve the problems of low precision, complex operation, and bulky mold structure of traditional sheet insert fixing methods in the prior art, which cannot effectively adapt to special process requirements, resulting in inaccurate positioning and low production efficiency. To achieve the above objectives, this application provides the following technical solution: A rotating retainer for an in-mold surface decorative insert includes a fixed base, under which a positioning pin and a countersunk screw are respectively connected. The fixed base is provided with a fixing device for limiting the position of an external structure. The fixing device is covered with a rotating device for rotating outside the fixing device. A push plate is connected to one side of the rotating device.

[0005] Optionally, the fixing device includes a rectangular groove, which is formed in the fixing seat, and two vertical plates are connected in the rectangular groove, with the same rotating shaft connected to the two vertical plates.

[0006] Optionally, the fixing seat has two semi-circular grooves, and the rotating shaft extends into the semi-circular grooves.

[0007] Optionally, the rotating device includes a pressing plate, a push plate is fixedly connected to one side of the pressing plate, two sleeves are symmetrically arranged under the pressing plate, the sleeves are sleeved on the outside of the rotating shaft, and a return torsion spring is sleeved on the rotating shaft.

[0008] Optionally, the rotating shaft and the sleeve form a rotatable connection structure.

[0009] Optionally, one end of the reset torsion spring is engaged in the pressing plate, and the other end of the reset torsion spring is engaged in the rectangular groove. Compared with the prior art, this application has at least the following beneficial effects: 1. In this utility model, when it is necessary to place the insert sheet, the pressing plate is rotated open, and then the insert sheet is inserted under the push plate. Then the pressing plate is released, and at this time the reset torsion spring applies elastic force to the pressing plate, so that the pressing plate drives the sleeve to rotate outside the rotating shaft. At this time, the pressing plate drives the push plate to rotate synchronously. After the insert sheet under the push plate is subjected to force, it can be easily placed into the mold, thereby improving the positioning accuracy and production efficiency of the sheet insert. Moreover, the structure is simple, the size is very small, and it can be flexibly set to the desired process requirement position. It is especially suitable for large, non-porous or curved plastic molds. It can be stably fixed in high temperature environment and can be used as a standardized component of the mold.

[0013] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please see Figures 1-4 , This utility model provides a technical solution: an in-mold surface decorative insert rotating fixture, including a fixing base 1, a positioning pin 2 and a countersunk screw 3 respectively connected to the fixing base 1, a fixing device 4 for limiting the external structure is provided inside the fixing base 1, a rotating device 5 for rotating outside the fixing device 4 is provided outside the fixing device 4, and a push plate 6 is connected to one side of the rotating device 5.

[0014] Specifically, such as Figures 1-4 As shown, the fixing device 4 includes a rectangular groove 41, which is formed inside the fixing base 1. Two vertical plates 42 are connected inside the rectangular groove 41, and the same rotating shaft 43 is connected to the two vertical plates 42. Two semi-circular grooves are formed inside the fixing base 1, and the rotating shaft 43 extends into the semi-circular grooves. The rotating device 5 includes a pressing plate 51, and a push plate 6 is fixedly connected to one side of the pressing plate 51. Two sleeves 52 are symmetrically arranged below the pressing plate 51. The sleeves 52 are sleeved outside the rotating shaft 43. By setting the sleeves 52 and the rotating shaft 43, the sleeves 52... 2. When rotating outside the rotating shaft 43, the rotating shaft 43 can limit the sleeve 52 to prevent the sleeve 52 from shaking or dislodging during rotation; the rotating shaft 43 is fitted with a reset torsion spring 53. By setting the reset torsion spring 53, the reset torsion spring 53 can apply elastic force to the pressing plate 51, so that the pressing plate 51 can rotate quickly and reset; the rotating shaft 43 and the sleeve 52 form a rotating connection structure. One end of the reset torsion spring 53 is locked in the pressing plate 51, and the other end of the reset torsion spring 53 is locked in the rectangular groove 41.

[0015] During operation, when insert sheet material needs to be placed, rotate to open the pressing plate 51, then insert the insert sheet material into the push plate 6, and then release the pressing plate 51. At this time, the reset torsion spring 53 applies elastic force to the pressing plate 51, causing the pressing plate 51 to drive the sleeve 52 to rotate outside the rotating shaft 43. At this time, the pressing plate 51 drives the push plate 6 to rotate synchronously. After the insert sheet material under the push plate 6 is subjected to force, it can be easily placed into the mold. When insert sheet material is inserted, the push plate 6 can limit the insert sheet material to avoid displacement during the pressing process, thereby improving the positioning accuracy and production efficiency of the sheet insert.

[0016] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
