Description

Technical Field

[0001] This utility model relates to the field of automotive parts injection molding technology, specifically a demolding structure for an air filter cover injection mold. Background Technology

[0002] With the automotive industry's ever-increasing demand for plastic components such as air filter caps, injection molding technology has become a crucial production process in this field. Air filter caps, as one of the essential air filtration components in automobiles, typically require precision injection molds for molding during production. Traditional injection mold designs often have limitations in their demolding structures, leading to less smooth demolding processes and consequently affecting production efficiency and product quality. Many existing mold designs rely on single mechanical structures or complex component mating, which can easily cause mold jamming, component damage, and scratches or tears on the product's appearance during demolding.

[0003] Traditional injection mold demolding structures often rely on combinations of components such as sliding cores and ejector pins. These components may experience positional misalignment and inaccurate movement during demolding. Especially when processing complex shapes, existing molds often cannot guarantee that the product surface will not be damaged during demolding. Furthermore, after prolonged use, the moving parts of the mold may wear out significantly, leading to decreased demolding accuracy and impacting production efficiency. In addition, the complex structure of existing molds often requires multiple adjustments and replacements of parts, increasing production costs and maintenance complexity.

[0004] Another drawback of existing mold designs is insufficient demolding accuracy and stability, leading to dimensional deviations and appearance defects in mass production. These problems not only affect the stability of the production process but also increase the cost of subsequent inspection and repair. Therefore, while ensuring high precision and high quality, traditional molds often face a series of challenges such as poor demolding smoothness, high processing difficulty, and low production efficiency, urgently requiring optimization and improvement through innovative design.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] like Figures 1-9 As shown in the figure, the present invention provides a demolding structure for an air filter cover injection mold, including a mold base plate 1, and a filter cover mold base 2 is provided on the surface of the mold base plate 1. An installation groove 11 is provided on the side of the mold base plate 1, and a cylinder seat 8 is provided inside the installation groove 11. A telescopic cylinder 7 is installed on the surface of the cylinder seat 8. A fixing groove 13 is provided on the surface of the mold base plate 1, and a fixing base 9 is provided on both sides inside the fixing groove 13.

[0032] Two fixed bases 9 are slidably connected to a slider seat 6 on their sides. A pin seat 5 is slidably connected inside the slider seat 6, and an air inlet pin 4 is connected to the side of the pin seat 5. The telescopic end of the telescopic cylinder 7 is connected to the surface of the pin seat 5, and the air inlet pin 4 passes through the slider seat 6 and is connected to the side of the pin seat 5.

[0033] The fixed base 9 has a first guide slide on its side, and the slider seat 6 has a first guide strip on its side. The slider seat 6 is slidably connected to the side of the fixed base 9 through the cooperation of the first guide strip and the first guide slide.

[0034] The slider seat 6 has a second guide slide inside, and the pin holder 5 has a second guide strip on its side. The pin holder 5 is slidably connected to the inside of the slider seat 6 through the cooperation of the second guide strip and the second guide slide.

[0035] The slider seat 6 has a positioning block 14 inside.

[0036] The slider seat 6 is connected to the side of the sliding guide block 10, and the surface of the sliding guide block 10 is provided with a receiving groove 18. The sliding block 15 is slidably connected inside the receiving groove 18. One end of the driving block 16 is connected to the surface of the slider seat 6. The lower surface of the sliding block 15 is provided with a T-shaped groove. The upper surface of the driving block 16 is provided with a T-shaped slider, and the sliding block 15 is slidably connected to the driving block 16 through the cooperation of the T-shaped slider and the T-shaped groove.

[0037] Guide platforms are provided on both sides of the sliding block 15, and vertical guide grooves 17 are provided on both sides inside the receiving groove 18. A drive block 16 is slidably connected to the lower surface of the sliding block 15. The guide platforms on the sliding block 15 are tightly slidably connected to the vertical guide grooves 17, and the setting angle of the guide platforms and the vertical guide grooves 17 is 1 degree or more relative to the vertical direction of the sliding guide block 10, biased towards the slider seat 6. Preferably, it is 1 degree (see reference). Figure 8 , 9 ).

[0038] In one embodiment of this utility model, before demolding, the air inlet pin 4 is embedded inside the filter cover product 3, while the sliding block 15, the driving block 16, and the sliding guide block 10 are in close contact with the filter cover product 3. During demolding, the telescopic end of the telescopic cylinder 7 drives the pin holder 5 to move horizontally, and the pin holder 5 drives the air inlet pin 4 fixedly connected to it to move horizontally together, thus demolding it from the filter cover product 3.

[0039] When the side of the needle holder 5 abuts against the positioning block 14 on the slider holder 6, and the needle holder 5 continues to be driven, the needle holder 5 drives the slider holder 6 to slide on the fixed base 9 through the positioning block 14. At this time, the slider holder 6 drives the drive block 16 and the position guide block 10 fixedly connected to it to move together. The position guide block 10 will disengage from the groove 19 on the filter cover product 3, and the drive block 16 will also disengage from the surface of the filter cover product 3.

[0040] Since the drive block 16 and the sliding block 15 are connected by a T-shaped sliding connection, the support thickness of the drive block 16 gradually decreases during the retraction process, thereby driving the sliding block 15 to slide downward inside the receiving groove 18, and causing the guide platform to slide downward inside the vertical guide groove 17.

[0041] Specifically, the engagement angle between the guide platform of the sliding block 15 and the vertical guide groove 17 is 1 degree or more off-center from the vertical direction of the sliding guide block 10 towards the slider seat 6. Therefore, the sliding block 15 will shift away from the filter cover product 3 and eventually separate from it. This offset angle is designed taking into account the outer surface shape of the filter cover product 3, especially its outer surface surface which has a certain slope, to ensure that the sliding block 15 can be demolded smoothly and to avoid damage to the product surface.

[0042] During the demolding process, the precise drive of the telescopic cylinder 7, the translation of the insert seat 5, and the cooperation of the positioning block 14 ensure smooth movement of all components of the mold, guaranteeing high efficiency and precision. Furthermore, due to the angular offset design, the sliding block 15 avoids direct contact with the surface of the filter cover product 3, effectively reducing the risk of surface scratches and ensuring the appearance quality of the filter cover product. Simultaneously, this design reduces the complexity of mold processing, making the mold structure simpler, improving production efficiency, reducing wear during long-term use, and extending the mold's service life.

[0043] Overall, this demolding structure effectively solves the problems of jamming, surface damage, and high processing difficulty associated with traditional molds during demolding. Simultaneously, through rational structural design and motion coordination, it optimizes mold stability and precision, improving production efficiency while ensuring product quality. This technical solution is not only suitable for the production of complex precision plastic parts in industries such as automotive, electronics, and home appliances, but also holds promise for wider application in high-precision injection molding, demonstrating a promising market outlook.

[0044] In this embodiment, a floating limiting block 12 is installed inside the fixed groove 13, and the floating limiting block 12 is in close contact with the lower surface of the slider seat 6.

[0045] This design significantly improves mold stability and demolding accuracy. The floating limit block 12, through contact with the slider seat 6, provides additional support and restraint during mold operation, preventing excessive shaking or displacement of the slider seat 6 during movement, thereby ensuring the overall structural stability of the mold.

[0046] Furthermore, the floating limit block 12 provides more precise limiting functionality, controlling the movement range of the slider seat 6 and preventing incomplete or uneven mold demolding due to errors. In this way, the mold can maintain high precision during multiple demolding cycles, reducing product defects and dimensional errors caused by unstable movement. Moreover, the design of the floating limit block 12 can alleviate the instability that may arise from the hydraulic transmission system driven by the cylinder, ensuring smoothness and consistency during demolding, thereby improving mold lifespan and production efficiency.

[0047] In summary, this invention solves the problems of difficult demolding, product appearance damage, and high processing difficulty that traditional molds encounter during long-term use by optimizing the demolding structure design. Through the introduction of innovative designs such as floating limit blocks, precise angular offset, and T-shaped sliding connections, the mold's movement is more stable, the demolding process is smoother, and scratches and damage to the product surface are effectively reduced. This technology not only improves the demolding accuracy and service life of the mold but also reduces manufacturing costs and processing difficulty, enhances production efficiency, and has significant economic benefits and application prospects.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
