[0058] The following is in conjunction with the appendix Figure 1 To be continued Figure 28 The specific embodiments of the present invention will be described in detail below. It should be noted that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the present invention. Example 1

[0059] This embodiment uses a single mold and a single cavity. This embodiment provides a camera base injection mold for molding. Figures 1-3The camera base 1 is a camera base injection mold comprising an upper mold 2 and a lower mold 3. The lower mold 3 has a lower molding insert 4 connected to an ejector mechanism and a gating device. The gating device is located on the lower mold 3, ensuring the product material exits from the back of the product, guaranteeing a smooth overall appearance and eliminating gate marks. The upper mold 2 includes a panel 5, with an A-plate 6 at its lower part. An upper cavity 7 is formed on the A-plate 6, and a side molding device 8 is installed within the upper cavity 7. Multiple cooling holes 9 are provided within the A-plate 6 for installing cooling pipes to cool the mold; this is a conventional technique and will not be elaborated upon here. The upper cavity 7, lower molding insert 4, and side molding device 8 work together to form the camera base 1. The side molding device 8 includes two... A side forming slider 11 is used to form the side hole 10 of the workpiece. The shape of the part of the side forming slider 11 that mates with the side hole 10 of the workpiece is made according to the side hole 10 of the workpiece, which will not be described in detail here. The side forming slider 11 extends to the top of the A plate 6. The two shoulders 60 on the top of the side forming slider 11 are provided with clamping blocks 12. The clamping blocks 12 are placed in the clamping block mounting groove 13 on the top of the A plate 6. The clamping blocks 12 and the clamping block mounting groove 13 are connected by screws. A shovel base 14 is slidably arranged between the two side forming sliders 11. The shovel base 14 extends to the panel 5. The top of the shovel base 14 is fixedly connected to the panel 5 by fastening screws 15. When the panel 5 is separated from the A plate 6, the panel 5 drives the shovel base 14 to move, thereby driving the two side forming sliders 11 to be removed from the side hole 10 of the workpiece.

[0060] The lower mold 3 includes a B plate 16, on which a lower mounting cavity 17 is provided. A lower forming insert 4 is installed in the lower mounting cavity 17. The lower forming insert 4 is fixed to the lower mounting cavity 17 by screws or the like. The B plate 16 is connected to the base plate 19 by a mold leg 18. The mold leg 18 is connected to the B plate 16 and the base plate 19 by screws or the like.

[0061] Preferably, in order to achieve precise positioning and improve processing accuracy, positioning protrusions 20 are provided on the four corners of the B plate 16, and positioning grooves 21 that cooperate with the positioning protrusions 20 are provided on the A plate 6; as is well known, the upper mold 2 is provided with guide pillars 22, and the lower mold 3 is provided with guide sleeves 23 that cooperate with the guide pillars 22, so as to facilitate the positioning and opening and closing of the mold.

[0062] The working principle of this embodiment is as follows: After the mold is closed, the injection molding machine pours through the pouring device set in the lower mold 3. After pouring is completed, the mold is opened after cooling. The panel 5 and the A plate 6 are separated first. The shovel base 14 moves to drive the side forming slider 11 to disengage from the workpiece side hole 10. Then the A plate 6 and the B plate 16 are opened. The hydraulic injection molding machine uses the hydraulic pump to convert the mechanical energy of the electric motor into the pressure energy of the hydraulic oil. The hydraulic oil enters the oil cylinder through the pipeline and control elements, pushes the oil cylinder piston to move, drives the ejection mechanism to move, and ejects the molded camera base 1. Example 2

[0063] This embodiment describes the lower molded insert 4, specifically:

[0064] The lower molding insert 4 includes a main molding insert 24, which includes a double-ear molding part 25 and a bottom molding part 26. The double-ear molding part 25 cooperates with the upper cavity 7 to form the double ears 51 of the camera base. The bottom molding part 26 cooperates with the upper cavity 7 to form the base 27. The bottom molding part 26 has a through hole 28, and a lower mounting hole molding insert 29 and a lower mounting hole molding insert 30 are disposed in the through hole 28. The lower mounting hole molding insert 29 and the lower mounting hole molding insert 30 are used to form the mounting post 31 of the camera base. Specifically:

[0065] The lower mounting hole forming insert 29 includes an inner hole forming rod 32, which is used to form the inner hole 33 of the mounting column 31. An outer wall forming rod 34 is provided on the outside of the inner hole forming rod 32, and the outer wall forming rod 34 cooperates with the inner hole forming rod 32 to form the outer wall 35 of the mounting column 31. The bottom plane of the through hole 28 contacts the top plane of the outer wall forming rod 34. The lower mounting hole forming insert 30 includes a first forming section 36, a second forming section 37, and a third forming section 38 connected in sequence. The diameters of the first forming section 36, the second forming section 37, and the third forming section 38 increase sequentially. The lower mounting hole forming insert 30 is designed to form the mounting column 31 without affecting the ejection mechanism, thus better achieving ejection. The first forming section 36, the second forming section 37, and the third forming section 38... 37. The three sections 38 are integrally formed. The diameter of the first section 36 is equal to the diameter of the inner hole 33, and the length of the first section 36 is equal to the length of the inner hole 33. The inner hole forming rod 32 includes an inner hole forming section 1 39, an inner hole forming section 2 40, and an inner hole forming section 31 connected in sequence. The diameters of the inner hole forming sections 1 39, 2 40, and 3 41 increase sequentially. The diameter of the inner hole forming section 1 39 is equal to the diameter of the inner hole 33, and the length of the inner hole forming section 1 39 is equal to the length of the inner hole 33. The outer wall forming rod 34 of the mounting hole is set on the outside of the inner hole forming section 2 40, and the top of the outer wall forming rod 34 of the mounting hole is flush with the top of the inner hole forming section 2 40. Example 3

[0066] This embodiment describes the ejection mechanism, specifically:

[0067] The ejection mechanism includes an ejector pin 42 and an inclined ejector rod 43. The inclined ejector rod 43 extends to the arc-shaped portion 44 of the double-ear forming portion 25. The inclined ejector rod 43 is connected to the inclined ejector seat 45, which is fixed to the top plate 46 by screws or other structures. The ejector pin 42 extends to the narrow walls 47 on both sides of the double-ear forming portion 25 and the top of the bottom forming portion 26. The ejector pin 42 is connected to the top plate 46. A bottom plate 48 is provided at the lower part of the top plate 46.

[0068] This application uses the cooperation of ejector pin 42 and inclined ejector rod 43 to eject the injection-molded camera base 1, resulting in a better ejection effect. The ejection marks are on the back of the camera base 1, which does not affect the aesthetics of the camera base 1 and can ensure the processing accuracy of the camera base 1. Example 4

[0069] This embodiment describes the casting device, specifically:

[0070] The casting device includes a hot runner 49, which is fixed on the base plate 19 and extends to the top of the bottom forming part 26 through the top plate upper plate 46 and the bottom plate lower plate 48; a positioning ring 50 is provided at the corresponding position on the outer side of the hot runner 49 on the base plate 19.

[0071] The injection molding machine injects material into the camera base molding cavity, which consists of the upper cavity 7, the lower molding insert 4, and the side molding device 8, through the hot runner 49, to form the camera base 1. In this embodiment, the casting device is inverted, and the product material exits from the back of the product. There are no gate marks on the product appearance, ensuring the overall smoothness of the product appearance. Example 5

[0072] To better control the separation of panel 5 from board A 6 and board A 6 from board B 16, in this embodiment, a pull rod is fixed on panel 5. The pull rod extends from board A 6 to board B 16. The pull rod includes a rod body 52, and a movable part 53 is provided at the bottom of the rod body 52. ​​The diameter of the movable part 53 is larger than the diameter of the rod body 52. ​​The movable part 53 extends into the placement groove 54 of board B 16.

The top of the rod body 52 is flush with board A 6, and a connecting bolt 61 is provided on panel 5 to fix the pull rod.

[0073] Preferably, a rubber plug 58 is provided on the B plate 16, and a rubber plug hole 59 is provided on the A plate 6 to cooperate with the rubber plug 58; during the mold opening process, the rubber plug 58 rubs against the A plate 6 to fasten it to the A plate 6.

[0074] Under the action of the rubber stopper 58, plate B 16 is fastened to plate A 6, and plate 5 is separated from plate A 6 first. The shovel base 14 drives the side forming slider 11 to move, and the moving part 53 of the pull rod moves along the moving groove 55. When plate A 6 moves to the limit distance of the pull rod, plate A 6 and plate B 16 open. The injection molding machine outputs hydraulic power to the oil cylinder, and the oil cylinder makes an ejection action, so that the formed camera base 1 is separated from the lower forming insert 4, and the product is taken out. Example 6

[0075] This embodiment provides a method for injection molding a camera base, including the following steps:

[0076] Step 1: Mold closing. The injection molding machine pours the material through the gating device set in the base plate 19. Specifically, the material enters the camera base molding cavity composed of the upper cavity 7, the lower molding insert 4, and the side molding device 8 through the hot runner 49 to form the camera base 1.

[0077] Step 2: After injection molding is complete, open the mold after cooling;

[0078] Step 3: Panel 5 and A plate 6 are separated first, and the shovel base 14 moves to drive the slider of side forming 11 to disengage from the workpiece side hole 10 of camera base 1.

[0079] Step 4: When plate A6 moves to the limit distance of the pull rod, plate A6 and plate B16 open;

[0080] Step 5: The injection molding machine outputs power through the hydraulic system to drive the ejection mechanism to eject the molded camera base 1;

[0081] Step Six: Repeat steps one through five.

[0082] In summary, due to the adoption of the above technical solution, this application has the following advantages:

[0083] 1. One shovel base drives two side forming sliders to move, which can realize simultaneous demolding of both sides undercutting in a small space;

[0084] 2. The fit between the lower molding insert and the upper cavity, with the mold parting from the bottom of the camera base, ensures that the parting line on the product surface is neat and follows the regular shape of the product, without any other clamping lines.
