Description

Technical Field

[0001] This utility model relates to the field of optical module component molding technology, specifically to an optical module component demolding molding device. Background Technology

[0002] Optical module components have complex structures, and traditional machining is inefficient and costly. Metal injection molding technology is used to produce high-precision optical module components. Through mold forming, production efficiency is improved while the processing cost is expected to be reduced to one-third of that of machining. Injection molding requires molding equipment. After molding, the optical module components are demolded for further debinding and sintering.

[0003] In a movable device for injection molding with an arc-shaped handle disclosed in existing patent publication number CN223147598U, the demolding mechanism includes a mold shell, which is slidably connected to the outer wall of a sliding rod. The outer wall of the mold shell has multiple circular holes (I). A control rod (I) is slidably connected to the inner wall of each circular hole (I). Multiple circular holes (II) are opened on the front side of the mold shell, and a control rod (II) is slidably connected to the inner wall of each circular hole (II). Multiple springs are fixedly connected to the rear side of each control rod (I), and a fixing plate is fixedly connected to the rear side of each spring. The control rod (II) is placed in the circular holes (II) and positioned on the inner wall of the mold groove. The fixing plates on both sides of the springs help the control rods (I) and (II) reset. When the mold shell moves to the left, its right outer wall disengages from the mold cover plate, and the springs release their thrust, causing the control rods (I) and (II) to move to the right. Because the control rod (I) is in contact with the inner wall of the mold groove when it contracts, when the control rod (I) moves to the right, it ejects the injection-molded product from the mold.

[0004] In the aforementioned equipment, demolding after injection molding mainly relies on control lever one and control lever two ejecting the injection-molded product under the action of springs. However, the reliability of demolding is affected by the spring-released thrust. To address these issues, a demolding device for optical module components is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a demolding and molding device for optical module components to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A demolding and molding device for optical module components, including a base;

[0008] A cover mounted on top of a machine base, comprising a frame and a mounting base disposed within the frame; and a fixed mold mounted on the frame.

[0011] And a demolding mechanism is provided on the side of the moving frame near the moving mold, which includes a moving plate slidably disposed between the upper and lower sets of connecting seats and a fixed block connected to one side of the moving mold. The moving plate is connected to the moving plate through a buffer member. A demolding ejector is installed on one side of the moving plate and inserted into the moving mold. A pressing frame is installed on one side of the mounting seat to press the moving plate closer to the moving mold.

[0013] In one alternative: the buffer includes a first spring and a sliding rod connected to the side of the fixed block away from the moving mold, the end of the first spring away from the fixed block contacting a pad block on one side of the moving plate, and the sliding rod sliding through a sliding hole in the moving plate.

[0014] In one alternative embodiment: the ejector includes a fixed plate mounted on the side of the movable plate near the moving mold, a plurality of ejector pins are connected to the fixed plate, and the moving mold is provided with ejector holes for the ejector pins to pass through.

[0015] In one alternative: the top and bottom of the movable plate are both connected to adsorption iron blocks, and electromagnets corresponding to the adsorption iron blocks are installed on the side of the two sets of connecting seats that are close to each other.

[0016] In one alternative: it also includes a discharge mechanism installed in the base for discharging the optical module component after it has been ejected between the fixed mold and the moving mold.

Four sets of second springs are connected to the bottom of the guide plate, and the height of the end of the guide plate near the hopper is lower than the height of the end of the guide plate away from the hopper.

[0019] In one alternative: the machine cover further includes a protective cover attached to the frame and a movable cover slidably disposed on the top of the frame.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] In this utility model, the demolding mechanism is directly integrated between the connecting seats of the moving mechanism, without the need for additional equipment space. The structure is compact, and the demolding action is linked with the mold opening process, resulting in a rapid response. During demolding, the pressure frame continuously squeezes the moving plate, causing it to slide along the sliding rod towards the moving mold. The buffer effectively absorbs the impact force of the pressure frame, making the ejection process smooth and gentle, and avoiding scratches on the product surface or structural deformation.

[0022] This invention can quickly adapt to the production needs of different types of optical module components by replacing the fixed mold, the moving mold, and the corresponding demolding ejector pins, and has strong versatility. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5 In this embodiment, the optical module component demolding and molding device includes a base 1;

[0032] The machine cover 2, which is installed on the top of the machine base 1, includes a frame 21 and a mounting base 22 disposed within the frame 21; and a fixed mold 3, which is installed on the frame 21.

[0033] The moving mold 4 is located on one side of the fixed mold 3;

[0034] The moving mechanism 5 is used to adjust the movement of the moving mold 4. It includes a moving frame 51 and a connecting seat 52 connecting the moving mold 4 and the moving frame 51. The mounting seat 22 is equipped with a moving component for adjusting the movement of the moving frame 51.

[0035] And a demolding mechanism 6 is provided on the side of the movable frame 51 near the moving mold 4. It includes a movable plate 61 slidably disposed between the upper and lower sets of connecting seats 52 and a fixed block 62 connected to one side of the moving mold 4. The movable plate 61 is connected by a buffer. A demolding ejector is installed on one side of the movable plate 61 and inserted into the moving mold 4. A pressing frame 55 is installed on one side of the mounting seat 22 to press the movable plate 61 toward the moving mold 4. The movable plate 61 is slidably disposed between the connecting seats 52, without occupying extra space, and is adapted to the demolding requirements of optical module components of different specifications.

[0036] Using the above scheme, after the optical module component is formed between the fixed mold 3 and the moving mold 4, the moving mechanism 5 drives the moving mold 4 to separate from the fixed mold 3. The demolding process is linked with the movement of the moving mold 4. The pressing frame 55 on one side of the mounting base 22 presses the moving plate 61, and the demolding ejector is ejected.

[0037] like Figure 3 As shown, the movable component includes a hydraulic telescopic rod 53 installed on the side of the mounting base 22 away from the moving mold 4. The movable rod at the power output end of the hydraulic telescopic rod 53 passes through the mounting base 22 and connects to the movable frame 51. Four sets of guide rods 54 are connected between the fixed mold 3 and the mounting base 22. The moving mold 4 is provided with guide holes 41 that slide with the guide rods 54. Specifically, the hydraulic telescopic rod 53 can adjust the movement of the movable frame 51, thereby driving the moving mold 4 to move. The guide rods 54 provide stable guidance for the movement of the moving mold 4.

[0038] like Figure 4 As shown, the buffer includes a first spring 63 and a sliding rod 64 connected to the side of the fixed block 62 away from the moving mold 4. The end of the first spring 63 away from the fixed block 62 contacts a pad on the side of the moving plate 61, and the sliding rod 64 slides through a sliding hole on the moving plate 61. Specifically, the buffer composed of the first spring 63 and the sliding rod 64 can alleviate the impact force of the pressure frame 55 on the moving plate 61, reduce mechanical wear, and extend the service life of the mechanism. At the same time, the first spring 63 can assist the moving plate 61 to reset.

[0039] like Figure 4 As shown, the ejector component includes a fixed plate installed on the side of the movable plate 61 near the moving mold 4. Several ejector pins 65 are connected to the fixed plate. The moving mold 4 is provided with ejector holes for the ejector pins 65 to pass through. Specifically, the size and model of the ejector pins 65 can be set according to actual needs. Through the precise matching of the ejector pins 65 and the ejector holes of the moving mold 4, the optical module components are ensured to be subjected to uniform force, avoiding product deformation or damage due to excessive local force.

[0040] like Figure 4 As shown, the top and bottom of the movable plate 61 are connected to adsorption iron blocks 67, and electromagnets corresponding to adsorption iron blocks 67 are installed on the side of the two sets of connecting seats 52 that are close to each other. Specifically, the cooperation between the electromagnets and the adsorption iron blocks 67 realizes the control of the demolding action. When the moving mold 4 needs to move away from the fixed mold 3, the electromagnets are de-energized, the adsorption force disappears, and the pressing frame 55 on the side of the mounting seat 22 squeezes the movable plate 61, causing it to move towards the moving mold 4 along the sliding rod 64. At this time, the demolding ejector rod 65 passes through the demolding hole of the moving mold 4 and pushes the molded optical module component out of the cavity. After demolding is completed, the moving mechanism 5 drives the moving mold 4 to reset, and the first spring 63 pushes the movable plate 61 to reset under the action of the fixed block 62. The demolding ejector rod 65 exits the demolding hole of the moving mold 4, and the electromagnet is energized again to adsorb the movable plate 61, waiting for the next molding cycle.

[0041] like Figure 2 As shown, it also includes a discharge mechanism 7 installed in the base 1, which is used for the discharge of the optical module mechanism component after it is ejected between the fixed mold 3 and the moving mold 4.

[0042] like Figure 2 As shown, the base 1 includes a base body 11 and a discharge cavity 12 disposed within the base body 11. The top of the base body 11 is provided with a discharge port corresponding to the space between the fixed mold 3 and the moving mold 4. The discharge cavity 12 is connected to the discharge port, and one side of the discharge cavity 12 is connected to the outside. Specifically, after the fixed mold 3 and the moving mold 4 are separated, the formed optical module component is ejected and can be discharged from the discharge port.

[0043] like Figure 5 As shown, the discharge mechanism 7 includes a guide plate 71 disposed in the discharge chamber 12. The guide plate 71 has an opening near the discharge chamber 12 with a hopper 73 installed in the discharge chamber 12. Four sets of second springs 72 are connected to the bottom of the guide plate 71. The height of the end of the guide plate 71 near the hopper 73 is lower than the height of the end of the guide plate 71 away from the hopper 73. Specifically, after the formed optical module component is ejected, it falls onto the guide plate 71 through the discharge port. The second springs 72 can act as a buffer. The formed optical module component slides along the top of the guide plate 71 into the hopper 73, making it easy for personnel to remove.

[0044] like Figure 1 and Figure 2 As shown, the housing 2 also includes a protective cover 23 connected to the frame 21 and a movable cover 24 slidably disposed on the top of the frame 21; specifically, the movable cover 24 moves to facilitate cleaning and replacement of the fixed mold 3 and the moving mold 4. In actual use, the corresponding fixed mold 3 and moving mold 4 can be replaced according to the specific model of the optical module mechanism.

[0045] The working principle of this utility model is as follows: the hydraulic telescopic rod 53 pushes the moving frame 51 to move towards the fixed mold 3, and drives the moving mold 4 to slide along the guide rod 54 until it is completely closed with the fixed mold 3 to form a closed cavity. Molten plastic is injected into the cavity, and the optical module mechanism is cooled and formed in the mold. After the injection molding is completed, the hydraulic telescopic rod 53 retracts, pulls the moving frame 51 and the moving mold 4 to move and separate from the fixed mold 3. When the pressure frame 55 fixed on the mounting base 22 comes into contact with the moving plate 61, the electromagnet on the connecting base 52 is de-energized, and the moving plate 61 is no longer attracted and fixed. The pressure frame 55 continues to squeeze the moving plate 61, so that it overcomes the pre-tightening force of the first spring 63 and slides along the sliding rod 64 towards the moving mold 4.

[0046] The movement of the movable plate 61 causes the demolding ejector pin 65 in front of it to be inserted into the demolding hole of the moving mold 4, which smoothly ejects the formed optical module mechanism from the cavity, and the buffer absorbs the impact force of the pressure frame 55.

[0047] After demolding is completed, the hydraulic telescopic rod 53 pushes the moving mold 4 to reset, preparing for the next mold closing. The pressure frame 55 disengages from the moving plate 61. Under the action of the rebound force of the first spring 63, the moving plate 61 drives the demolding ejector rod 65 to return to its original position.

[0048] When the electromagnet is energized, it re-attracts the adsorption block 67 on the moving plate 61, fixing it in place, waiting for the next demolding cycle;

[0049] The ejected optical module components fall into the guide plate 71 through the discharge port. Under the buffering effect of the second spring 72, the components are protected from collision damage. They automatically slide into the hopper 73 by the tilt angle of the guide plate 71, completing the material collection and making it convenient for operators to collect them.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
