Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a molding die for an automotive blow-molded spoiler. Background Technology

[0002] In automobile manufacturing, spoilers are important aesthetic and functional components. They reduce air resistance, increase downforce, and improve vehicle stability and fuel economy by altering airflow over the vehicle's surface. Currently, automotive spoilers are commonly produced using blow molding, which offers advantages such as high production efficiency and low cost. However, the structural design of the molding die directly affects the production quality and efficiency of the spoiler. Traditional automotive blow-molded spoiler molds typically employ a front mold and a one-piece rear mold structure, commonly known as a two-part mold. Because the rear mold is a fixed, one-piece structure, demolding complex-shaped spoilers can easily lead to problems such as demolding difficulties and damage to the spoiler surface. This not only affects the product yield but also increases production costs and reduces production efficiency. Therefore, this invention provides a reasonably structured, easily adjustable, and convenient demolding automotive blow-molded spoiler molding die. Utility Model Content

[0024] like Figures 1 to 5As shown, a molding die for a blow-molded automotive spoiler includes a front mold 1 and a combined rear mold. Both the front mold 1 and the combined rear mold are made of high-quality mold steel, possessing good strength and wear resistance. The combined rear mold includes a rear mold body 2 and a rear mold split body 3, the latter being movable relative to the rear mold body 2.

[0025] The molding die of this application, through the design of a combined rear mold, forms a three-part mold structure that can move relatively. During the production process, after blow molding is completed, the front mold is first driven to separate from the combined rear mold. Then, the rear mold split 3 is driven to move relative to the rear mold body 2, thereby expanding the demolding space. Finally, the molded automotive blow-molded spoiler is ejected by the ejection device, thus smoothly completing the demolding operation. For automotive blow-molded spoilers 5 with complex shapes, demolding can be easily achieved, avoiding damage to the spoiler surface caused by demolding difficulties, and greatly improving the product qualification rate.

[0026] In the specific implementation process of this application, see [link / reference]. Figure 4 and Figure 5 The rear mold body 2 is equipped with multiple parallel slide rails 21. These slide rails 21 are manufactured using high-precision machining processes, resulting in a smooth surface and high straightness. The rear mold sub-body 3 is equipped with a sliding connector 31 that matches the slide rails 21. The sliding connector 31 is fixed to the rear mold sub-body 3 by bolts and is slidably connected to the slide rails 21, allowing it to slide freely on the slide rails 21. This sliding connection structure provides stable guidance and support for the movement of the rear mold sub-body 3, ensuring that it can move smoothly and stably along a predetermined direction. This allows for relative position adjustment between the rear mold sub-body 3 and the rear mold body 2, improving the overall stability and reliability of the mold and thus adapting to the production needs of complex-shaped spoilers.

[0027] In the specific implementation process of this application, see [link / reference]. Figures 1 to 4 The rear mold body 2 is equipped with a drive device 4 to drive the movement of the rear mold segment 3, realizing automated control of the movement of the rear mold segment 3, eliminating the need for manual operation, reducing labor costs, and improving production efficiency. During the demolding process, the drive device 4 can move the rear mold segment 3, changing the internal structure of the mold, creating favorable conditions for the demolding of the spoiler, reducing demolding difficulties and product damage, and improving product quality and production efficiency. The drive device 4 can be selected from either a cylinder or a hydraulic motor. Cylinders and hydraulic motors have the advantages of strong power, fast response speed, and high control precision, providing stable and sufficient power for the movement of the rear mold segment 3, meeting the needs of different working conditions, and reducing errors and labor intensity caused by manual operation.

[0028] In the specific implementation process of this application, see [link / reference]. Figure 4 and Figure 5The drive unit 4 is equipped with an output shaft, which has a slot. The rear mold body 3 is equipped with a snap-fit ​​component 32, which engages with the slot. This snap-fit ​​mechanism enables power transmission between the drive unit 4 and the rear mold body 3. The structure is simple and the connection is robust, effectively ensuring that the power from the drive unit 4 is accurately transmitted to the rear mold body 3, allowing the rear mold body 3 to move according to predetermined requirements and guaranteeing the long-term stable operation of the mold.

[0029] As an example, in this embodiment, the driving device 4 uses a cylinder, which is fixedly installed on one side of the rear mold body 2. One end of the cylinder output shaft has a rectangular groove that matches the size of the snap-fit ​​component 32 on the rear mold body 3. The snap-fit ​​component 32 on the rear mold body 3 has a T-shaped limiting groove, enabling a tight snap-fit ​​with the end of the cylinder output shaft that has the groove. During production, after blow molding is completed, the cylinder starts working, the output shaft retracts, and the snap-fit ​​component 32 and the rear mold body 3 move backward along the slide rail 21, expanding the demolding space. Then, the ejector device smoothly ejects the molded automotive blow-molded spoiler 5 from between the front mold 1 and the rear mold, completing the demolding operation. After demolding, the cylinder extends, driving the rear mold body 3 to reset, ready for the next production cycle.

[0030] In other embodiments, the drive device 4 can also be a hydraulic motor. Hydraulic motors have higher torque output, enabling them to meet the demolding requirements of larger and heavier automotive blow-molded spoilers. The output shaft of the hydraulic motor is also equipped with a slot, and the engagement method between the locking member 32 of the rear mold assembly 3 and the slot is the same as described above. During production, the hydraulic motor provides power through the hydraulic system, enabling more precise control of the movement speed and displacement of the rear mold assembly 3, further improving production stability and product quality.

[0031] When using the molding die of this application to produce a blow-molded automotive spoiler, the front mold 1 and the combined rear mold are first joined together to form the spoiler's molding cavity. Then, plastic raw material is injected into the molding cavity through a blow molding process to form the spoiler. After the spoiler is formed, a demolding operation is required. At this time, the drive device 4 is activated, and the output shaft of the drive device 4 drives the rear mold body 3 to move along the slide rail 21, changing the internal structure of the mold and creating a certain gap between the spoiler and the mold to facilitate the demolding of the spoiler. After demolding is completed, the drive device 4 is turned off, allowing the rear mold body 3 to return to its initial position, preparing for the next molding.

[0032] It should also be noted that, without conflict, the embodiments of this utility model and the features therein can be combined with each other to obtain new embodiments.

The scope of protection of the present utility model should be determined by the scope of the claims. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model.
