Description

Technical Field

[0001] This utility model belongs to the field of mold technology and relates to an injection mold for a motorcycle rearview mirror housing with a sloping ejector structure. Background Technology

[0002] In the production of motorcycle rearview mirror housings, injection molds are crucial equipment. Traditional injection molds often face difficulties in demolding rearview mirror housings with complex structures. For example, when the housing has angled slots or specially shaped protrusions, conventional demolding methods may lead to product damage and low production efficiency. Furthermore, existing mold structures are insufficient to meet the growing market demands in terms of molding precision, mold lifespan, and automation. Therefore, there is an urgent need to design a motorcycle rearview mirror housing injection mold with an angled ejector structure that can overcome these shortcomings.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a motorcycle rearview mirror frame processing mold [application number: 201921121448.3], which includes a base, a lower mold, an upper mold, and a protective shell. The lower mold is fixedly connected to the right side of the base, and the upper mold is located on the right side of the lower mold. An injection port is fixedly connected to the outside of the lower mold, and a fixing plate is provided on the surface of the lower mold. A vibration motor is connected to the surface of the fixing plate through a bolt seat, and a protective shell is installed on the outside of the vibration motor. This motorcycle rearview mirror frame processing mold adds a vibration motor to the outside of the lower mold and combines it with the ejection mechanism inside the mold. After the workpiece inside the mold is processed, the vibration motor first generates vibration force, which is transmitted to the inside of the mold cavity through a vibration rod, thereby vibrating and separating the workpiece from the mold cavity. Then, the ejection mechanism ejects the workpiece. However, this solution has the drawbacks of easy product damage and low production efficiency when dealing with rearview mirror housings with hole and groove structures that are different from the demolding direction. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a motorcycle rearview mirror housing injection mold with an inclined ejector structure.

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

[0006] A motorcycle rearview mirror housing injection mold with an inclined ejector structure includes a lower mold and an upper mold. The lower mold has a lower insert plate with two housing forming protrusions. An inclined straight ejector combined ejector structure extending into the lower mold and matching the shape of the housing forming protrusions is located below the lower mold. The upper mold has an upper insert plate with two forming cavities. The housing forming protrusions are directly opposite the forming cavities. A slot forming sliding assembly is provided between the lower and upper molds, capable of reciprocating linear motion along one end near or away from the housing forming protrusions.

[0007] In the above-mentioned injection mold for a motorcycle rearview mirror housing with an inclined ejector demolding structure, the inclined and straight ejector combined demolding structure includes an ejector fixing plate disposed below the lower mold of the motorcycle rearview mirror housing. The ejector fixing plate is provided with a plurality of inclined ejector rods and straight ejector rods, and the top of the inclined ejector rods is provided with an auxiliary molding block.

[0008] In the above-mentioned injection mold for a motorcycle rearview mirror housing with an inclined ejector structure, the inclined ejector rod and the ejector fixing plate are slidably connected by a sliding block, the inclined ejector rod and the straight ejector rod are arranged in a cross configuration, and the auxiliary molding block corresponds to the position of the housing molding protrusion and is matched in shape.

[0009] In the above-mentioned injection mold for a motorcycle rearview mirror housing with an inclined ejection structure, a first cylinder is provided on both sides of the lower mold for forming the motorcycle rearview mirror housing. A fixing block is connected to the power shaft of the first cylinder, and the fixing block is connected to the ejection fixing plate.

[0010] In the above-mentioned injection mold for a motorcycle rearview mirror housing with an inclined ejector structure, the slot forming sliding assembly includes a first sliding block and a second sliding block disposed between the lower mold and the upper mold of the motorcycle rearview mirror housing. The second sliding block is provided with a slot forming shaft, and the first sliding block and the second sliding block are arranged opposite each other.

[0011] In the above-mentioned injection mold for a motorcycle rearview mirror housing with a sloping ejector structure, the upper mold for forming the motorcycle rearview mirror housing is provided with cylinder fixing brackets at both ends, and the cylinder fixing brackets are provided with slidable inner sliding connecting blocks. The tails of the first sliding block and the second sliding block are provided with sloping sliding heads that slide in cooperation with the inner sliding connecting blocks.

[0012] In the above-mentioned injection mold for a motorcycle rearview mirror housing with a sloping top demolding structure, the inner sliding connecting block is provided with a sloping sliding groove, the sloping sliding head is slidably engaged with the sloping sliding groove, and the cylinder fixing bracket is provided with a second cylinder for driving the inner sliding connecting block to slide.

[0013] In the above-mentioned injection mold for a motorcycle rearview mirror housing with an inclined top demolding structure, the center lines of the first sliding block and the second sliding block are perpendicular to the center line of the inner sliding connecting block. When the inner sliding connecting block slides along the inside of the cylinder fixing bracket, the inclined sliding head slides in conjunction with the inclined sliding groove. The trajectory of the inclined groove drives the first sliding block and the second sliding block to reciprocate linearly towards or away from the housing forming protrusion.

[0014] In the above-mentioned injection mold for a motorcycle rearview mirror housing with an inclined ejector structure, a limiting frame plate is provided between the lower mold for forming the motorcycle rearview mirror housing and the upper mold for forming the motorcycle rearview mirror housing, and the first sliding block and the second sliding block are respectively slidably engaged with the limiting frame plate.

[0015] In the above-mentioned injection mold for a motorcycle rearview mirror housing with an inclined ejector structure, an injection main board is provided above the upper mold for forming the motorcycle rearview mirror housing.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. In use, this utility model is equipped with a combined inclined and straight ejector demolding structure. By intersecting the inclined ejector rods and straight ejector rods and adapting the auxiliary forming block at the top of the inclined ejector rod to the forming protrusion of the shell, it can effectively meet the demolding requirements of complex-shaped shells. Compared with the traditional single ejection method, it greatly improves the success rate of demolding and product quality, and reduces the risk of product damage during the demolding process.

[0018] 2. This utility model, through the first sliding block, the second sliding block, and the inclined slide head that cooperates with the inner sliding connecting block, can accurately realize the forming of the hole and groove under the drive of the second cylinder, ensuring the dimensional accuracy and positional accuracy of the hole and groove, improving the overall quality of the product, and solving the problem of insufficient accuracy of traditional molds in hole and groove forming.

[0019] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, a motorcycle rearview mirror housing injection mold with an inclined ejector structure includes a lower mold 1 and an upper mold 2 for forming the motorcycle rearview mirror housing. The lower mold 1 has a lower insert plate 33 with two housing forming protrusions 3. Below the lower mold 1, there is an inclined straight ejector combined ejector structure 4 that extends into the lower mold 1 and matches the shape of the housing forming protrusions 3. The upper mold 2 has an upper insert plate 5 with two forming cavities 6. The housing forming protrusions 3 and forming cavities 6 are directly opposite each other. Between the lower mold 1 and the upper mold 2, there is a slot forming sliding assembly 7 that can reciprocate linearly along one end close to or away from the housing forming protrusions 3.

[0027] In this embodiment, during the injection molding process, the lower insert 33 plays an important supporting and positioning role within the lower mold 1 for forming the motorcycle rearview mirror housing. Two housing forming protrusions 3 are disposed within the lower insert 33, and their shapes are precisely adapted to the internal shape of the motorcycle rearview mirror housing. During the injection molding process, these two housing forming protrusions 3 provide crucial shape support for the forming of the internal structure of the housing. The inclined and straight ejector combined demolding structure 4 is located below the lower mold 1 for forming the motorcycle rearview mirror housing and extends into the lower mold 1, matching the shape of the housing forming protrusions 3. During the demolding stage, the inclined and straight ejector combined demolding structure 4 plays a key role in smoothly ejecting the formed housing from the mold. Within the upper mold 2 for forming the motorcycle rearview mirror housing, the upper insert 5 is securely installed, and the two protrusions 3 within the upper insert 5... The molding cavity 6 is directly opposite the shell molding protrusion 3 of the lower mold. When the mold is closed, the shell molding protrusion 3 and the molding cavity 6 are precisely aligned, forming a complete molding cavity for the motorcycle rearview mirror shell. The slot molding sliding assembly 7 is located between the lower mold 1 and the upper mold 2 of the motorcycle rearview mirror shell. Its function is to perform the molding operation on the slot structure on the motorcycle rearview mirror shell during the injection molding process. Overall, this structural design is closely coordinated, enabling the mold to complete the injection molding of the motorcycle rearview mirror shell efficiently and accurately. Its beneficial effect is that, through the coordinated work of various components, the integrated molding from the shell body to the slot structure is achieved, improving production efficiency, reducing errors caused by multiple processing steps, and ensuring the precision and quality of the product.

[0028] Combination Figure 1-4 As shown, the inclined and straight ejector combined demolding structure 4 includes an ejector fixing plate 8 disposed below the lower mold 1 for forming the motorcycle rearview mirror housing. The ejector fixing plate 8 is provided with a plurality of inclined ejector rods 9 and straight ejector rods 10. The top of the inclined ejector rods 9 is provided with an auxiliary forming block 11.

[0029] Specifically, because the angled ejector rod 9 has an inclination angle, it can move along a specific trajectory during demolding. The auxiliary molding ejector block 11, along with the movement of the angled ejector rod 9, applies appropriate ejection force to the specific part corresponding to the shell molding protrusion 3. At the same time, the straight ejector rod 10 also pushes upward. The two work together to achieve full ejection of the shell. The beneficial effects of this design are significant. The cooperation between the angled ejector rod 9 and the auxiliary molding ejector block 11 can cleverly avoid the complex internal structure of the shell and accurately apply force to key parts, avoiding damage to the product during demolding. The synergistic effect of the straight ejector rod 10 ensures that the shell can be ejected stably and fully, greatly improving the efficiency and quality of demolding.

[0030] The inclined push rod 9 and the ejector fixing plate 8 are slidably connected by a slide block 12. The inclined push rod 9 and the straight push rod 10 are arranged crosswise. The auxiliary forming top block 11 corresponds to the position of the shell forming protrusion 3 and the shape is suitable.

[0031] In this embodiment, the slide block 12 provides a stable track for the movement of the inclined ejector rod 9 on the ejector fixing plate 8, enabling the inclined ejector rod 9 to slide precisely and stably along a predetermined trajectory. The inclined ejector rod 9 and the straight ejector rod 10 are arranged in a cross configuration. This layout makes full use of the space inside the mold. During demolding, the inclined ejector rod 9 and the straight ejector rod 10 can apply ejection force to the shell from different angles. The auxiliary molding ejector block 11 and the shell molding protrusion 3 not only correspond in position but also match perfectly in shape. During demolding, the auxiliary molding ejector block 11 can accurately act on the part of the shell that needs to be ejected. Its function is that the slide block 12 ensures the accuracy and stability of the movement of the inclined ejector rod 9, making the demolding process more reliable. The cross configuration of the inclined ejector rod 9 and the straight ejector rod 10 can better adapt to the complex shape and structure of the shell, apply force evenly from multiple angles, and prevent the shell from being damaged due to uneven force. The precise matching of the auxiliary molding ejector block 11 and the shell molding protrusion 3 further improves the reliability of demolding, ensures the integrity of the product, and effectively reduces the defect rate of the product during the demolding process.

[0032] Combination Figure 2 , Figure 3 As shown, the lower mold 1 for forming the motorcycle rearview mirror housing is provided with a first cylinder 13 on both sides. A fixing block 14 is connected to the power shaft of the first cylinder 13, and the fixing block 14 is connected to the ejector fixing plate 8.

[0033] In this embodiment, the first cylinder 13 serves as the power source for the entire demolding action. The movement of the ejector plate 8 can be precisely controlled via the fixed block 14. During demolding, the first cylinder 13 is activated, its power shaft extends, and it drives the fixed block 14 to move, thereby pushing the ejector plate 8 upwards. At this time, the inclined ejector rod 9 and the straight ejector rod 10 eject the housing as the ejector plate 8 rises. This cylinder-driven method has significant advantages over traditional manual or other mechanical drive methods. It greatly improves the degree of automation. Operators only need to control the start and stop of the first cylinder 13 to achieve the demolding action, reducing the tediousness and errors of manual operation. Simultaneously, the cylinder drive provides a more stable and precise power output, making the movement of the ejector plate 8 smoother and the control precision higher, thereby effectively improving production efficiency and ensuring product quality consistency.

[0034] The slot forming sliding assembly 7 includes a first sliding block 15 and a second sliding block 16 disposed between the lower mold 1 and the upper mold 2 for forming a motorcycle rearview mirror housing. The second sliding block 16 is provided with a slot forming shaft 17, and the first sliding block 15 and the second sliding block 16 are arranged opposite each other.

[0035] In this embodiment, during the initial stage of the injection molding process, the first sliding insert 15 and the second sliding insert 16 are in specific positions, providing space for the filling of the injection molding material. When it is necessary to form a groove, they will slide along a predetermined trajectory. During the sliding process, the groove forming shaft 17 extrudes and forms the injection molding material, thereby forming a precise groove structure on the motorcycle rearview mirror housing. This structural design is highly flexible and can flexibly control the forming position and size of the groove by adjusting the sliding trajectory of the first sliding insert 15 and the second sliding insert 16 according to different product requirements. Its beneficial effects are that it improves the diversity of products, can meet the production needs of different styles of motorcycle rearview mirror housings on the market, enhances the versatility and adaptability of the mold, and reduces the cost incurred by enterprises due to mold replacement.

[0036] Combination Figure 2 As shown, the upper mold 2 for forming the motorcycle rearview mirror housing is provided with cylinder fixing brackets 18 at both ends. The cylinder fixing brackets 18 are provided with slidable inner sliding connecting blocks 19. The tails of the first sliding insert 15 and the second sliding insert 16 are provided with oblique sliding heads 20 that slide in cooperation with the inner sliding connecting blocks 19.

[0037] In this embodiment, a slidable inner sliding connecting block 19 is disposed within the cylinder fixing bracket 18. The tail ends of the first sliding insert 15 and the second sliding insert 16 are provided with inclined sliding heads 20. The inclined sliding heads 20 are slidably engaged with the inner sliding connecting block 19. The sliding of the inner sliding connecting block 19 can drive the inclined sliding heads 20 to move. Thus, through the connection between the inclined sliding heads 20 and the first sliding insert 15 and the second sliding insert 16, the sliding of the first sliding insert 15 and the second sliding insert 16 is realized. This design achieves efficient power transmission and precise motion control of the components through ingenious mechanical connection and sliding engagement. Its function is that the cylinder fixing bracket 18 ensures the stability of the movement of the inner sliding connecting block 19. The engagement of the inner sliding connecting block 19 and the inclined sliding heads 20 transforms the linear motion of the inner sliding connecting block 19 into the sliding of the first sliding insert 15 and the second sliding insert 16 in a specific direction, so that the slot forming sliding assembly 7 can move precisely according to a predetermined trajectory, providing a reliable guarantee for the precise forming of the slot.

[0038] The inner sliding connecting block 19 is provided with an inclined sliding groove, and the inclined sliding head 20 is slidably engaged with the inclined sliding groove. The cylinder fixing bracket 18 is provided with a second cylinder 21 for driving the inner sliding connecting block 19 to slide.

[0039] In this embodiment, when the second cylinder 21 is started, it drives the inner sliding connecting block 19 to slide within the cylinder fixing bracket 18. Since the inclined sliding head 20 cooperates with the inclined sliding groove in the inner sliding connecting block 19, the linear motion of the inner sliding connecting block 19 is converted into the sliding of the inclined sliding head 20 in a specific direction through the inclined sliding groove. This drives the first sliding insert 15 and the second sliding insert 16 to make reciprocating linear motions toward or away from the housing forming protrusion 3. This method of using the inclined sliding groove and cylinder drive can accurately control the movement trajectory and position of the first sliding insert 15 and the second sliding insert 16. Its beneficial effect is that, compared with other simple driving methods, the design of the inclined sliding groove can convert linear motion into more complex and precise specific direction motion, which meets the high precision requirements of the hole and groove forming for the movement trajectory of the sliding component, ensures the accuracy of hole and groove forming, and improves the quality and consistency of the product.

[0040] Combination Figure 1-3 As shown, the center lines of the first sliding block 15 and the second sliding block 16 are perpendicular to the center line of the inner sliding connecting block 19. When the inner sliding connecting block 19 slides along the inside of the cylinder fixing bracket 18, the inclined sliding head 20 slides in conjunction with the inclined sliding groove. The trajectory of the inclined groove drives the first sliding block 15 and the second sliding block 16 to reciprocate linearly towards or away from the end of the housing forming protrusion 3.

[0041] In this embodiment, the center lines of the first sliding block 15 and the second sliding block 16 are perpendicular to the center line of the inner sliding connecting block 19. When the inner sliding connecting block 19 slides along the inside of the cylinder fixing bracket 18, the inclined sliding head 20 slides in conjunction with the inclined sliding groove. The trajectory of the inclined groove drives the first sliding block 15 and the second sliding block 16 to reciprocate linearly towards or away from the shell forming protrusion 3. This vertical setting and inclined groove coordination makes the motion conversion more stable and precise. Its function is that the vertical center line and the inclined groove coordination can better adapt to the complex spatial structure inside the mold, and achieve precise motion control in a limited space. Compared with the traditional parallel setting or simple linear drive method, this design can provide a more flexible and stable motion mode, ensuring that the first sliding block 15 and the second sliding block 16 move more smoothly during the movement, better meeting the needs of hole and groove forming, and improving the reliability and service life of the mold.

[0042] Combination Figure 1-3 As shown, a limiting frame plate 22 is provided between the lower mold 1 for forming the motorcycle rearview mirror housing and the upper mold 2 for forming the motorcycle rearview mirror housing. The first sliding block 15 and the second sliding block 16 are respectively slidably engaged with the limiting frame plate 22.

[0043] In this embodiment, the limiting frame plate 22 restricts the movement range of the first sliding block 15 and the second sliding block 16, ensuring their stability and accuracy during the sliding process. At the same time, the limiting frame plate 22 also enhances the stability of the overall mold structure, preventing the product quality from being affected by the shaking of the components during the injection molding process. Its beneficial effect is that, by setting the limiting frame plate 22, the accuracy of the movement of the slot forming sliding component 7 is guaranteed, the slot forming error caused by component movement deviation is reduced, and the product qualification rate is improved. In addition, the limiting frame plate 22 enhances the stability of the overall mold structure, extends the service life of the mold, and reduces the production cost of the enterprise.

[0044] Combination Figure 1 As shown, an injection molding main board 23 is provided above the upper mold 2 for forming the motorcycle rearview mirror housing.

[0045] In this embodiment, during the injection molding process, the injection molding main board 23 ensures that the injection molding material is uniformly filled into the cavity formed by the shell forming protrusion 3 and the forming cavity 6, as well as the space formed by the slot forming sliding assembly 7. Its function is to ensure the molding quality and dimensional accuracy of the product by precisely controlling the injection molding parameters. Different products have different requirements for injection molding parameters, and the injection molding main board 23 can be flexibly adjusted according to product needs to ensure that each motorcycle rearview mirror shell can meet the high-quality molding standard, improve the consistency and stability of the product, and meet the strict requirements of the market for product quality.

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

[0047] Before the injection molding process begins, the mold is installed on the injection molding machine and adjusted. First, the first sliding insert 15 and the second sliding insert 16 are in their initial positions, and the slot forming shaft 17 is in a ready state. The injection main plate 23 injects the molten injection material into the cavity composed of the housing forming protrusion 3 of the lower mold 1 for forming the motorcycle rearview mirror housing and the forming cavity 6 of the upper mold 2 for forming the motorcycle rearview mirror housing. At the same time, the material also fills the space around the slot forming sliding assembly 7. After the injection molding is completed and cooled and solidified, the demolding operation begins. The first cylinder 13 is started, and its power shaft pushes the ejector plate 8 upward through the fixing block 14. At this time, the inclined ejector rod 9 and the straight ejector rod 10 are pushed upward together. The auxiliary forming ejector block 11 at the top of the inclined ejector rod 9 pushes the housing forming protrusion upward. When the corresponding part is pushed out, due to the tilt angle of the inclined push rod 9, its movement trajectory can cleverly avoid the complex structure inside the shell and push the shell out of the mold. At the same time, the second cylinder 21 is started, driving the inner sliding connecting block 19 to slide in the cylinder fixing bracket 18. The inclined sliding groove in the inner sliding connecting block 19 cooperates with the inclined sliding head 20, driving the first sliding insert 15 and the second sliding insert 16 to slide away from the shell forming protrusion 3. The hole groove forming shaft 17 is pulled out from the formed hole groove, completing the demolding operation of the hole groove forming sliding assembly 7. Throughout the process, the limiting frame plate 22 ensures the stability of the movement of the first sliding insert 15 and the second sliding insert 16, so that the mold can efficiently and accurately complete the injection molding and demolding of the motorcycle rearview mirror shell.
