Technical Field
[0001] This utility model relates to the technical field of lens barrel injection molding equipment, specifically to a lens barrel injection mold that facilitates material handling. Background Technology
[0002] The camera lens barrel is an important component of a mobile phone camera. In the processing of mobile phone camera lens barrels, injection molding is the most common method. Mobile phone camera lens barrel injection molds are key tools used to manufacture mobile phone camera lens barrels, which can effectively improve the efficiency of injection molding production of mobile phone camera lens barrels.
[0003] For example, the utility model patent disclosed in publication number CN219820484U, a mobile phone lens barrel injection mold for easy material handling, belongs to the field of mobile phone lens barrel injection molding technology. This easy-to-handle mobile phone lens barrel injection mold includes a mold body, a dredging mechanism, and a material handling mechanism. The mold body includes a lower mold base with several fixing holes on its top. An installation cavity is formed inside the lower mold base, and the installation cavity is connected to the fixing holes. A sleeve is installed in each fixing hole, and a fixing rod is slidably connected inside the sleeve. A stop plate is installed at the bottom of the fixing rod, and a through hole is formed at the center of the bottom of the sleeve. The material handling mechanism includes a first threaded rod and a second threaded rod, both of which are mounted inside the installation cavity via bearings. A coupling connects the first and second threaded rods, and the threads of the first and second threaded rods are opposite to each other. Through the use of the material handling mechanism, the entire collection lens barrel inside the mold can be ejected at once, achieving a rapid material handling effect.
[0004] Although the aforementioned equipment can eject the molded lens barrel parts via a connecting rod, its ejection structure, which uses a lead screw and connecting rod, is overly complex, resulting in insufficient durability and high cost. Furthermore, the stability of ejecting the molded lens barrel parts is also insufficient, reducing the equipment's practicality in processing these parts. Therefore, there is an urgent need for a lens barrel injection mold that facilitates material removal to address these issues. Utility Model Content

[0011] Preferably, the material guiding device includes a supporting base plate, with fixed sliding shafts provided at the four corners of the upper end face of the supporting base plate, and return springs provided at the four corners of the upper end face of the supporting base plate and coaxially with the supporting base plate. Material guiding slide plates are provided at equal intervals on the upper part of the supporting base plate, and a sealing push ring is provided at the top of the material guiding slide plates. Pen-shaped cylinders are symmetrically arranged on the side of the upper end face of the supporting base plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model, by setting up an injection molding device and a material guiding device, enables the automated ejection and unloading of the mirror barrel injection molded parts. Two sets of pen-shaped cylinders can synchronously drive the support base plate and multiple sets of material guiding slide plates to move upward. The material guiding slide plates can drive the injection molded parts inside the injection cavity to move upward synchronously through the sealing push ring. This effectively improves the automation level of the equipment for synchronous ejection of multiple injection molded parts, and also improves the stability of the equipment for ejecting injection molded parts.

[0024] Injection cavity 8 is equidistantly opened on the upper end face of injection mold 4, and injection mold core 1 is provided at the middle of the inner end face of injection cavity 8. Injection mold core 1 is used for shaping and support.
[0025] Injection molding device 2 is fixedly installed on the upper part of the limiting guide seat 7. Injection molding device 2 is used to inject molding into the inside of injection mold 4.
[0026] The material guiding device 5 is elastically slidably engaged with the lower end face of the injection mold 4. The material guiding device 5 is used to extract and export the injection molded parts inside the injection mold 4.
[0027] like Figure 3 The injection molding device 2 includes a positioning top plate 27. A thin cylinder 21 is provided at the upper center of the positioning top plate 27, and an upper injection mold 23 is provided at the output end of the thin cylinder 21. A guide tube 22 is provided at the center of the front end face of the upper injection mold 23. Injection heads 24 are provided at equal intervals on the lower end face of the upper injection mold 23. Two sets of support pins 26 are provided on the side end face of the positioning top plate 27 opposite to the corner. Two sets of positioning guide pins 25 are symmetrically provided on the side of the lower end face of the upper injection mold 23.
[0028] like Figure 4 The material guiding device 5 includes a support base plate 51. Fixed sliding shafts 52 are provided at the four corners of the upper end face of the support base plate 51, and return springs 53 are provided at the four corners of the upper end face of the support base plate 51 and at the coaxial position of the support base plate 51. Material guiding slide plates 55 are provided at equal intervals on the upper part of the support base plate 51, and a sealing push ring 54 is provided on the top of the material guiding slide plate 55. Pen-shaped cylinders 56 are symmetrically arranged on the side of the upper end face of the support base plate 51.
[0029] The upper injection mold 23 is adapted to the positioning guide groove 3 through the positioning guide shaft 25 and is slidably engaged on the upper surface of the lower injection mold 4. This can effectively improve the stability of the axial displacement of the upper injection mold 23 on the upper part of the lower injection mold 4, thereby improving the accuracy of subsequent injection positioning.
[0030] The upper injection mold 23 is then sealed and engaged with the upper part of the injection cavity 8 via the injection head 24. The opening of the injection head 24 does not contact the injection mold core 1. The injection head 24 can seal and engage the upper opening of the injection cavity 8, thereby improving the stability of subsequent injection molding.

[0032] Working principle: Before injection molding, the operator can connect the external material supply conduit to the guide pipe 22 to facilitate the rapid introduction of the injection molding material into the upper injection mold 23. During injection molding, the operator can activate the thin cylinder 21, which moves the bottom upper injection mold 23 downward. Subsequently, the upper injection mold 23 is positioned and closed at the opening of the injection cavity 8 by the injection head 24. After alignment, the external material supply conduit can supply material to the upper injection mold 23 through the guide pipe 22, and then the injection head 24 can guide the material into the injection cavity 8. The injection molding operation is completed inside cavity 8. When the lens barrel injection molded part is shaped and unloading is carried out, two sets of pen-shaped cylinders 56 are activated. At this time, the pen-shaped cylinders 56 can drive the bottom support plate 51 to rise. The support plate 51 can drive multiple sets of guide slide plates 55 and sealing push rings 54 to move upward synchronously. At this time, the sealing push rings 54 can eject the lens barrel injection molded part inside the injection molding cavity 8. Subsequently, the external material unloading module can collect the shaped lens barrel injection molded part. After collection, the reset spring 53 can drive the support plate 51 to elastically reset, which facilitates the subsequent cyclic ejection operation.
