Description

Technical Field

[0001] This utility model belongs to the field of mold technology and relates to a high-gloss injection molding mold for electric vehicle headlight decorative parts. Background Technology

[0002] With the rapid development of the electric vehicle industry, consumers' demands for the refinement of vehicle appearance are constantly increasing. Headlight trim, as a core visual component of the front fascia, not only needs to possess aesthetic decorative functions but also needs to meet the molding requirements of high-gloss surface quality and complex structures (such as multi-directional snap-fits and curved shapes). Traditional injection molds have many shortcomings in producing such products: 1. The snap-fit ​​structure at the side end of the trim is multi-directionally distributed. Traditional unidirectional core-pulling mechanisms easily lead to snap-fit ​​deformation after molding or tearing during demolding, directly affecting product assembly accuracy; 2. High-gloss surfaces require extremely high mold cavity smoothness and demolding stability. Traditional ejection structures, due to concentrated force, easily leave ejection marks on the product surface, destroying the high-gloss effect; 3. Insufficient coordination among the various moving components of the mold, causing interference or jamming during core-pulling and demolding actions, resulting in low production efficiency and a high scrap rate; 4. Waste material in the runner needs to be manually cleaned, which is not synchronized with product demolding, increasing the cost of subsequent processes and affecting production continuity. Therefore, it is essential to design a high-gloss injection molding mold for electric vehicle headlight decorative parts that can adapt to complex structural molding, ensure high-gloss surface quality, and provide efficient and stable demolding.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a high-gloss molding mold for electric vehicle headlight decorative parts [Application No.: 202020824101.1], which includes an upper mold plate and a lower mold plate. Both the upper and lower mold plates have mold cavities. Multiple sliders are symmetrically fixedly connected to the side walls of the two mold cavities on opposite sides. The inner walls of the upper and lower mold plates have multiple grooves that match the sliders. Each groove has a positioning rod, and the two ends of the positioning rod are fixedly connected to the two side walls of the groove. Multiple sliders are movably sleeved with multiple positioning rods. Multiple positioning rods are also movably sleeved with springs, and the two ends of the springs are fixedly connected to the side walls of the grooves and the side walls of the sliders. However, this solution is still prone to deformation of the snap-fit ​​after molding or tearing during demolding during the core-pulling process, which directly affects the product assembly accuracy. During ejection, ejection marks are still easily left on the product surface, damaging the high-gloss effect. In addition, the waste material in the runner still needs to be manually cleaned. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a high-gloss injection molding mold for electric vehicle headlight decorative parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, a high-gloss injection molding mold for electric vehicle headlight decorative parts includes a lower mold 1 and an upper mold 2 for headlight decorative parts. An injection molded part 3 is provided above the upper mold 2. An upper mold embedded molding plate 4 is provided inside the upper mold 2. A lower mold embedded molding plate 5 is provided inside the lower mold 1 for headlight decorative parts. When the upper mold embedded molding plate 4 and the lower mold embedded molding plate 5 are fitted together, a cavity is formed. A side end auxiliary molding core-pulling component 6 that can move along one end close to or away from the lower mold embedded molding plate 5 is provided inside the lower mold 1 for headlight decorative parts. A straight inclined ejector auxiliary molding demolding structure 7 and a waste ejector 8 are provided below the lower mold 1 for headlight decorative parts. The straight inclined ejector auxiliary molding demolding structure 7 is slidably engaged with the lower mold embedded molding plate 5.

[0029] In this embodiment, during the injection molding process, the outlet of the injection molded part 3 is connected to the cavity, responsible for accurately introducing the molten plastic into the cavity; the upper mold 2 for forming the headlight trim part is embedded with the upper mold inlay plate 4 through the positioning groove, and the lower mold 1 for forming the headlight trim part is embedded with the lower mold inlay plate 5 at the corresponding position. The mating surfaces of the upper mold inlay plate 4 and the lower mold inlay plate 5 are precision ground, and after mating, they form a closed cavity that perfectly matches the shape of the electric vehicle headlight trim part, ensuring the dimensional accuracy of the product outline. The lower mold 1 for forming the headlight trim part has a sliding groove processed on its inner side, and the side end auxiliary forming core-pulling component 6 is installed in the sliding groove. It can move horizontally towards or away from the lower mold inlay plate 5 through the sliding rail structure in the groove, which can be used to form the headlight trim part. The molded cavity is closed at the side end during molding and detaches from the side structure of the product during demolding. A straight and inclined ejector molded demolding structure 7 and a waste ejector 8 are set below the lower mold 1 for the headlight decorative part. The top of the straight and inclined ejector molded demolding structure 7 passes through the reserved through hole of the lower mold embedded molding plate 5 and contacts the bottom of the cavity. The product demolding is completed through the combined vertical and inclined motion. The straight and inclined ejector molded demolding structure 7 and the through hole of the lower mold embedded molding plate 5 adopt a clearance fit to ensure smooth movement without jamming. By combining the multi-directional core pulling at the side end with the straight and inclined ejector composite demolding structure, a multi-component collaborative action mechanism is designed for the complex structural characteristics of the high-gloss decorative part, which is "buckle + curved surface". This solves the problem of product deformation and surface damage caused by the single action direction of traditional molds.

[0030] Combination Figure 1-5 As shown, the side end auxiliary molding core-pulling assembly 6 includes four end core-pulling slides 9 and two side core-pulling slides 10 disposed in the lower mold 1 for molding headlight trim. The end core-pulling slides 9 are provided with end molding core-pulling plates 11 on their inner sides, and the side core-pulling slides 10 are provided with side molding core-pulling plates 12 on their inner sides.

[0031] Specifically, during mold closing, the end core-pulling slide 9 and the side core-pulling slide 10 move along the slide rail towards the cavity, causing the end forming core-pulling plate 11 and the side forming core-pulling plate 12 to fit tightly with the upper mold inset forming plate 4 and the lower mold inset forming plate 5, together forming the side end contour of the cavity; during mold opening and core pulling, the core-pulling slide drives the core-pulling plate to move in the opposite direction, detaching from the side end structure of the product, realizing the core-pulling action. The distributed design of multiple sets of core-pulling slides and core-pulling plates can be adapted to different structures of the ends and sides of the decorative parts, avoiding motion interference of a single core-pulling mechanism, and improving the flexibility and accuracy of complex structure molding.

[0032] The inner side of the end-forming core-pulling plate 11 is provided with an end-snap forming protrusion 13, and the inner side of the side-forming core-pulling plate 12 is provided with a side-snap forming protrusion 14.

[0033] In this embodiment, when the mold is closed, the end snap-fit ​​protrusion 13 is embedded in the cavity, forming a complete structure of the end snap-fit ​​of the decorative part together with other molded components; when demolding and pulling the core, as the end core-pulling slide 9 moves horizontally, the end snap-fit ​​protrusion 13 disengages from the snap-fit ​​groove in the horizontal direction before the main body of the product, avoiding deformation or breakage of the snap-fit ​​under force, and the side snap-fit ​​protrusion 14 is seamlessly connected with the cavity wall, forming a complete outline of the side snap-fit, ensuring that the snap-fit ​​structure is full; when the mold is opened and the core is pulled, the side snap-fit ​​protrusion 14 disengages from the snap-fit ​​in the horizontal direction along with the side core-pulling slide 10, avoiding the pulling damage to the side snap-fit ​​caused by the traditional vertical demolding method.

[0034] The lower mold 1 for forming the headlight decorative part is provided with an end guide rail 15 and a side guide rail 16. The end core-pulling slide 9 is slidably engaged with the end guide rail 15, and the side core-pulling slide 10 is slidably engaged with the side guide rail 16.

[0035] In this embodiment, the end core-pulling slide block 9 is slidably engaged with the end guide rail 15 through a "T"-shaped groove, and the side core-pulling slide block 10 is slidably engaged with the side guide rail 16 through a "T"-shaped groove. The surface of the guide rail is coated with high-temperature wear-resistant grease.

[0036] Combination Figure 5 As shown, the straight and inclined ejector auxiliary molding and demolding structure 7 includes an ejector rod fixing slide plate 17 disposed below the lower mold 1 for headlight decorative parts. The ejector rod fixing slide plate 17 is provided with a straight ejector rod 18 and an inclined ejector rod 19. The inclined ejector rod 19 is connected to the ejector rod fixing slide plate 17 through a connecting slide block 20. The bottom of the inclined ejector rod 19 is in sliding engagement with the connecting slide block 20.

[0037] In this embodiment, the straight and inclined ejector-assisted molding and demolding structure 7 includes an ejector rod fixing slide plate 17 horizontally disposed below the lower mold 1 for forming the headlight trim. The ejector rod fixing slide plate 17 is slidably connected to the lower mold 1 for forming the headlight trim via four guide pillars and can move up and down in the vertical direction. The straight ejector rod 18 is vertically fixed on the ejector rod fixing slide plate 17, and its top passes through the through hole of the molding plate 5 embedded in the lower mold and contacts the bottom of the cavity. The inclined ejector rod 19 is installed on the ejector rod fixing slide plate 17 via a connecting slide block 20. The connecting slide block 20 is fixed to the ejector rod fixing slide plate 17 by bolts, and the connecting slide block 20 has a groove with an inclination angle of 15°. The slider at the bottom of the inclined ejector 19 is embedded in the slide groove and can slide along the slide groove. When the ejector fixed slide plate 17 rises, the straight ejector 18 pushes the product vertically. At the same time, the slider at the bottom of the inclined ejector 19 slides in the slide groove of the connecting slide block 20, so that the inclined ejector 19 generates horizontal displacement while rising, realizing the inclined demolding action. Through the inclined slide groove design of the connecting slide block, the vertical movement of the ejector fixed slide plate is cleverly transformed into the "vertical + horizontal" compound movement of the inclined ejector. Multi-directional demolding can be achieved without additional drive mechanism, simplifying the mold structure and improving the coordination and stability of the demolding action.

[0038] The top of the straight push rod 18 is provided with a first auxiliary forming insert 21, and the top of the inclined push rod 19 is provided with a second auxiliary forming insert 22. The first auxiliary forming insert 21 and the second auxiliary forming insert 22 are arranged alternately.

[0039] In this embodiment, the first auxiliary molding insert 21 and the second auxiliary molding insert 22 are staggered at the bottom of the cavity, and the top of the insert is flush with the bottom surface of the cavity of the lower mold embedded molding plate 5, together forming the complete bottom surface of the cavity.

[0040] Combination Figure 1-4 As shown, the lower mold embedded forming plate 5 has a flow channel 23, and the waste ejector 8 is located directly below the flow channel 23.

[0041] In this embodiment, the top of the waste ejector 8 is directly opposite the bottom end of the flow channel 23, and the corresponding position of the molded plate 5 embedded in the lower mold is machined with an ejection through hole to ensure that the solidified waste in the flow channel 23 can be completely ejected when the waste ejector 8 rises.

[0042] Combination Figure 1-4 As shown, the waste ejector 8 includes a waste straight ejector rod 24 disposed on the ejector rod fixing slide plate 17, and the waste straight ejector rod 24, straight ejector rod 18 and inclined ejector rod 19 are arranged alternately.

[0043] In this embodiment, the straight ejector pins 24, 18, and 19 are arranged in a matrix-like staggered pattern on the ejector pin fixing slide plate 17. The distance between each pin is greater than the stroke, ensuring that they do not interfere with each other during the ejection process. The staggered arrangement of the multiple pins avoids motion interference and ensures that the product ejection and waste ejection are synchronized, thus improving demolding efficiency. The clearance fit structure can effectively prevent molten plastic from overflowing into the gap between the ejector pin and the through hole, reducing the amount of mold cleaning work and lowering maintenance costs.

[0044] Combination Figure 1-2 As shown, the injection molded part 3 includes an injection main board 25, an injection manifold 26, and two injection tubes 27 disposed above the upper mold 2 for the headlight trim part.

[0045] In this embodiment, the injection molded part 3 includes an injection main board 25, an injection manifold 26, and two injection tubes 27. The injection main board 25 is fixedly installed on the top of the upper mold 2 for the headlight trim part by bolts. The injection manifold 26 is embedded in the groove of the injection main board 25 and is precisely positioned with the injection main board 25 by locating pins. One end of each of the two injection tubes 27 is connected to the outlet of an external injection molding machine through a flange, and the other end passes through the injection main board 25 and communicates with the flow channel inside the injection manifold 26. The multiple outlets of the injection manifold 26 are respectively connected to the inlet of the manifold 23 of the lower mold embedded molding plate 5 through pipes.

[0046] The working principle of this utility model is as follows:

[0047] During mold closing, the upper mold 2 and lower mold 1 of the headlight trim part are closed under the drive of the mold closing mechanism. The upper mold inner molding plate 4 and the lower mold inner molding plate 5 are tightly fitted to form a closed cavity. The end core-pulling slide 9 and the side core-pulling slide 10 of the side auxiliary molding core-pulling assembly 6 move towards the cavity along the end guide rail 15 and the side guide rail 16. The end molding core-pulling plate 11 and the side molding core-pulling plate 12 are fitted with the inner molding plate. The end snap-fit ​​molding protrusion 13 and the side snap-fit ​​molding protrusion 14 are embedded in the cavity to form a snap-fit ​​structure. The external injection molding machine injects molten plastic through the injection pipe 27, which is evenly introduced into the cavity through the injection manifold 26 and the manifold 23. After the plastic cools and solidifies, when the mold is opened and the core is pulled, the mold closing mechanism drives the upper mold 2 of the headlight trim part to move upward and separate from the lower mold 1 of the headlight trim part. The core-pulling slide of the auxiliary molding core-pulling assembly 6 moves in the opposite direction along the guide rail. The end molding core-pulling plate 11 and the side molding core-pulling plate 12 drive the snap-fit ​​molding protrusion to disengage from the product snap, completing the side end core-pulling action and preparing for subsequent demolding. During demolding, the ejection mechanism drives the ejector rod fixing slide plate 17 to move upward, simultaneously driving the straight ejector rod 18, the inclined ejector rod 19, and the waste straight ejector rod 24 to rise. The straight ejector rod 18 vertically pushes the bottom of the product through the first auxiliary molding insert 21, and the inclined ejector rod 19 tilts under the action of the sliding groove of the connecting slide 20, tilting and pushing the side of the product through the second auxiliary molding insert 22. The two work together to achieve demolding without damage to the product. At the same time, the waste straight ejector rod 24 ejects the solidified waste in the diversion channel 23, realizing the synchronous removal of the product and the waste. After the ejection is completed, each component is reset and enters the next production cycle.
