Description

Technical Field

[0001] This invention belongs to the field of mold technology, specifically an ejection structure for a lamp housing mold. Background Technology

[0002] Car lights are mainly used for illumination; they can be considered the eyes of a car. The headlight housing is an important component, and it is generally made using injection molding. The glass covers of the headlights and taillights of most vehicles are injection molded from high-grade polycarbonate.

[0003] During the manufacturing process of the lamp housing, the completed lamp housing needs to be removed from the mold, which is an important processing step. Since the structure of the lamp housing is generally quite complex, the lamp housing mold is also relatively complex. The lamp housing mold is characterized by its large size and weight.

[0004] In current technologies, when removing the lamp housing mold, some ejection mechanisms directly contact the surface of the lamp housing mold. This can cause scratches on the side surface of the mold when the mold and mold frame are separated, affecting the forming of the lamp housing.

[0005] Therefore, the present invention provides an ejection structure for a lamp housing mold. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: An ejection structure for a lamp housing mold, comprising a mold frame and a support base; the mold frame is composed of an upper mold frame, a lower mold frame, a front mold frame, a rear mold frame, a left mold frame, and a right mold frame; the upper mold frame is composed of a first frame and a second frame; an injection port is formed at the junction of the first frame and the second frame, as shown in the attached figure. Figure 1 As shown; cylinder frames are fixedly connected to both the left and right sides of the bearing seat; the telescopic ends of the two cylinder frames are respectively connected to the left mold frame and the right mold frame; a telescopic cylinder is fixedly connected to the lower part of the lower mold frame, and the outer surface of the telescopic cylinder is fixedly connected to the outer surface of the bearing seat;

[0008] During operation, in the initial state, the upper mold frame, lower mold frame, front mold frame, rear mold frame, left mold frame, and right mold frame are all joined together to form a sealed cavity. The first and second upper frames are also joined together to form the upper injection port. Molding liquid is injected into the sealed cavity through the injection port, gradually forming the lamp housing mold. When the lamp housing mold has cooled and solidified after a certain period, it needs to be removed. At this time, the extension end of the externally controlled cylinder moves, causing the extension end to drive the left and right mold frames respectively... The left and right mold frames move away from the lamp housing mold, separating them from the mold and no longer adhering to it. Then, the lower mold frame is lifted upwards by controlling the telescopic cylinder, ejecting the lamp housing mold. Finally, the worker can remove it. This invention divides the mold frame into multiple mold frames, allowing for individual removal of each frame, facilitating the ejection of the lamp housing mold. It also solves the problem in existing technologies where some ejection mechanisms directly contact the lamp housing mold, causing scratches on the mold's side surface, thus reducing the defect rate during lamp housing processing.

[0009] Preferably, a support frame is fixedly connected to the upper surface of each of the two cylinder frame telescopic ends; a connecting frame arranged symmetrically is fixedly connected to the outer surface of each support frame; a connecting wheel is rotatably connected to the surface of each connecting frame; symmetrically arranged columnar rods are fixedly connected to the upper surfaces of both the first and second frames; an arc-shaped seat is fixedly connected to the outer surface of each columnar rod; a telescopic spring is fixedly connected to the upper surface of each arc-shaped seat; and the connecting wheel is located near the lower surface of the arc-shaped seat.

[0010] During operation, as the cylinder frame extends and retracts, it moves the left and right mold frames away from each other. Simultaneously, the extension and retraction ends move the support frame on the upper surface, which in turn moves the connecting frame. Since the connecting wheel at one end of the connecting frame presses against the lower surface of the arc-shaped seat, the connecting wheel presses against the extension spring along the lower surface of the arc-shaped seat when the connecting frame and connecting wheel move. This causes the arc-shaped seat to move the column rod. The column rods at different positions move the first and second frames, respectively, causing the first and second frames to move away from the upper surface of the lamp housing mold. At this time, the mold frames on the top, left, and right sides of the mold are away from the mold surface, preventing the mold frames from sticking to the mold. This further facilitates the removal of the lamp housing mold and avoids scratches on the upper surface of the mold when the upper mold frames are removed.

[0011] Preferably, the outer surface of the arc-shaped seat has an arc-shaped groove on the middle side; the shape of the arc-shaped groove is adapted to the shape of the connecting wheel; the outer surface of the connecting frame is provided with a rotating shaft adapted to the connecting wheel;

[0012] During operation, an arc-shaped groove is opened on the surface of the arc-shaped seat, which helps to limit the positioning of the connecting wheel, thus facilitating the rolling of the connecting wheel inside the arc-shaped groove. This also facilitates the lifting of the arc-shaped seat by the connecting wheel, thereby facilitating the ejection of the first and second frames.

[0013] Preferably, the outer surfaces of both the first and second frames are provided with limiting grooves; the lower surface of the bearing seat is fixedly connected to a limiting post; the bottom end of the limiting post passes through the interior of the limiting groove.

[0014] During operation, limit slots and limit posts are provided to limit the movement of the first and second frames, preventing them from shifting during movement.

[0015] Preferably, an elastic compression column is fixedly connected to the outer surface of the bearing seat; an inclined seat is fixedly connected to one end of the elastic compression column near the mold frame; a pressing rod is fixedly connected to the outer surface of the telescopic end of the cylinder frame; the pressing rod and the inclined seat are arranged on the same plane; a fixing rod is fixedly connected to the outer surface of the inclined seat; two fixing rods are provided and are respectively fixedly connected to the outer surfaces of the front mold frame and the rear mold frame;

[0016] During operation, as the cylinder frame moves at its telescopic end, it simultaneously drives the pressure rod to move. During this movement, the pressure rod contacts and presses against the inclined surface of the inclined seat, causing the inclined seat to compress the elastic compression column. The inclined seat then drives the fixed rod to move a certain distance. Subsequently, the fixed rods at different positions will drive the front mold frame and the rear mold frame to move away from each other. Therefore, the upper mold frame, front mold frame, rear mold frame, left mold frame, and right mold frame of the mold frame will move away from the lamp housing mold, exposing the lamp housing mold to the outside. This ensures that every surface of the lamp housing mold is flat, avoiding scratches on its outer surface and improving the forming rate of the lamp housing mold.

[0017] Preferably, the shape of the pressure bar near the inclined seat is arc-shaped, which is beneficial for the pressure bar to press against the inclined seat and make the inclined seat move a certain distance; the outer surface of the elastic compression column is fixedly connected to a compression spring, which can facilitate the recovery of the elastic compression column when it is not compressed.

[0018] Preferably, each of the mold frames has symmetrically arranged embedded rods slidably connected to its outer surface; each of the mold frames has an electric rod fixedly connected to its outer surface; the top end of the electric rod is connected to the lower surface of the embedded rod; a pressing frame is rotatably connected to the outer surface of the embedded rod; a scraper is rotatably connected to the outer surface of the pressing frame; and a rotating column adapted to the pressing frame is provided on the outer surface of the embedded rod.

[0019] During operation, after the lamp housing mold is removed, the various mold frames are separated from each other. The operator can manually rotate the pressure frame, causing the pressure frame to drive the scraper to press against the inner side of the mold frame. Then, the electric rod is driven, causing the electric rod to move the embedding rod. The embedding rod then drives the scraper to move along the inner side of the mold frame, allowing the scraper to process the mold waste on the inner surface of the mold frame, thus automatically cleaning up the waste.

[0020] Preferably, a plurality of elastic rods are fixedly connected to the outer surface of the pressing frame; the plurality of elastic rods are arranged at equal intervals on the outer surface of the pressing frame; the side of each elastic rod away from the pressing frame is fixedly connected to the outer surface of the scraper.

[0021] During operation, multiple elastic rods are installed. These elastic rods can press against the outer surface of the scraper, so that the scraper is pressed tightly against the inner surface of the mold frame, which facilitates the scraper to remove waste material from the inner surface of the mold.

[0022] Preferably, each mold frame has a sliding groove on its outer surface that is adapted to the embedded rod; one end of the embedded rod is slidably connected inside the sliding groove; the sliding groove adapted to the embedded rod is provided to help maintain the embedded rod moving along the axis and facilitate the scraping of waste by the scraper.

[0023] Preferably, the outer surface of the bearing seat is provided with a circular groove adapted to the elastic compression column; one end of the elastic compression column passes through the interior of the circular groove; the circular groove facilitates the movement of the elastic compression column and the removal of the front and rear mold frames.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. The ejection structure of the lamp housing mold described in this invention uses a telescopic cylinder to lift the lower mold frame upwards, causing the lower mold frame to eject the lamp housing mold upwards, which can then be removed by the operator. This invention divides the mold frame into multiple mold frames, allowing different mold frames to be removed one by one, thus facilitating the ejection of the lamp housing mold. It also solves the problem in the prior art where some ejection mechanisms directly contact the lamp housing mold, causing scratches on the mold's side surface, thereby reducing the defect rate during lamp housing processing.

[0026] 2. The ejection structure of the lamp housing mold described in this invention uses an inclined seat to drive a fixed rod to move a certain distance. Then, the fixed rods at different positions will drive the front mold frame and the rear mold frame to move away from each other. Therefore, the upper mold frame, front mold frame, rear mold frame, left mold frame and right mold frame of the mold frame will move away from the lamp housing mold, exposing the lamp housing mold to the outside. As a result, each side of the lamp housing mold is flat, avoiding scratches on its outer surface and improving the forming rate of the lamp housing mold.

[0027] 3. The ejection structure of the lamp housing mold of the present invention, by rotating the pressing frame, causes the pressing frame to drive the scraper to press against the inner side of the mold frame, and then drives the electric rod to move the embedded rod. The embedded rod then drives the scraper to move along the inner side of the mold frame, so that the scraper can process the mold waste on the inner surface of the mold frame, thereby playing the role of automatically cleaning waste.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] Example 1

[0040] like Figures 1 to 7As shown in the figure, the ejection structure of a lamp housing mold according to an embodiment of the present invention includes a mold frame 1 and a support base 2; the mold frame 1 is composed of an upper mold frame, a lower mold frame, a front mold frame, a rear mold frame, a left mold frame, and a right mold frame; the upper mold frame is composed of a first frame 101 and a second frame 102; an injection port is formed at the junction of the first frame 101 and the second frame 102, as shown in the attached figure. Figure 1 As shown; cylinder frames 3 are fixedly connected to both the left and right sides of the bearing seat 2; the telescopic ends of the two cylinder frames 3 are respectively connected to the left mold frame and the right mold frame; a telescopic cylinder 4 is fixedly connected to the lower part of the lower mold frame, and the outer surface of the telescopic cylinder 4 is fixedly connected to the outer surface of the bearing seat 2.

[0041] In existing technologies, when removing the lamp housing mold, some ejection mechanisms directly contact the surface of the lamp housing mold. This can cause scratches on the mold side surface when the mold and mold frame separate, affecting the forming of the lamp housing. In the mold frame of this invention, in the initial state, the upper mold frame, lower mold frame, front mold frame, rear mold frame, left mold frame, and right mold frame are all joined together to form a sealed cavity. The first frame 101 and the second frame 102 above are joined together to form an injection port. Molding liquid is introduced into the sealed cavity through the injection port, gradually forming the lamp housing mold through the sealed cavity. After the lamp housing mold cools for a certain period of time... When the lamp housing mold needs to be removed during molding, the telescopic end of the external control cylinder frame 3 is moved, causing the telescopic end to drive the left and right mold frames to move away from the lamp housing mold respectively. The left and right mold frames separate from the lamp housing mold, so that they are no longer attached to the lamp housing mold. Then, the telescopic cylinder 4 is controlled to push the lower mold frame upward, so that the lower mold frame pushes the lamp housing mold upward, and finally the worker can take it out. The present invention divides the mold frame 1 into multiple mold frames, which can remove different mold frames one by one, thereby facilitating the ejection of the lamp housing mold. It also solves the problem in the prior art that some ejection mechanisms are in direct contact with the lamp housing mold, causing scratches on the side surface of the mold, thus reducing the defect rate during lamp housing processing.

[0042] Support frames 5 are fixedly connected to the upper surfaces of the telescopic ends of both cylinder frames 3; symmetrically arranged connecting frames 6 are fixedly connected to the outer surface of each support frame 5; connecting wheels 61 are rotatably connected to the surface of each connecting frame 6; symmetrically arranged columnar rods 7 are fixedly connected to the upper surfaces of the first frame 101 and the second frame 102; an arc-shaped seat 8 is fixedly connected to the outer surface of each columnar rod 7; a telescopic spring 81 is fixedly connected to the upper surface of each arc-shaped seat 8; the connecting wheels 61 are located on the lower surface near the arc-shaped seat 8.

[0043] During operation, when the telescopic ends of the cylinder frame 3 drive the left and right mold frames away from each other, the telescopic ends will simultaneously drive the support frame 5 on the upper surface to move. The support frame 5 drives the connecting frame 6 to move. Since the connecting wheel 61 at one end of the connecting frame 6 presses against the lower surface of the arc-shaped seat 8, when the connecting frame 6 and the connecting wheel 61 move, the connecting wheel 61 will press against the telescopic spring 81 along the lower surface of the arc-shaped seat 8, causing the arc-shaped seat 8 to drive the column rod 7 to move. The column rod 7 at different positions will drive the first frame 101 and the second frame 102 to move, so that the first frame 101 and the second frame 102 move away from the upper surface of the lamp housing mold. At this time, the mold frames on the top, left and right sides of the mold are away from the mold surface, so that the mold frames no longer stick to the mold, which further facilitates the removal of the lamp housing mold and avoids scratches on the upper surface of the mold when the upper mold frames are removed.

[0044] An arc-shaped groove 9 is formed on the outer surface of the arc-shaped seat 8 near its center; the shape of the arc-shaped groove 9 is adapted to the shape of the connecting wheel 61; the outer surface of the connecting frame 6 is provided with a rotating shaft adapted to the connecting wheel 61; the shape of the bottom surface of the arc-shaped seat 8 is as shown in the attached figure. Figure 4 As shown;

[0045] During operation, an arc-shaped groove 9 is formed on the surface of the arc-shaped seat 8, which helps to limit the position of the connecting wheel 61, thereby facilitating the rolling of the connecting wheel 61 inside the arc-shaped groove 9. This also facilitates the lifting of the arc-shaped seat 8 by the connecting wheel 61, thus facilitating the ejection of the first frame 101 and the second frame 102.

[0046] The outer surfaces of the first frame 101 and the second frame 102 are both provided with limiting grooves 10; the lower surface of the bearing seat 2 is fixedly connected to a limiting post 11; the bottom end of the limiting post 11 passes through the interior of the limiting groove 10.

[0047] During operation, a limiting groove 10 and a limiting post 11 are provided to limit the movement of the first frame 101 and the second frame 102, thereby preventing the first frame 101 and the second frame 102 from shifting during movement.

[0048] An elastic compression column 12 is fixedly connected to the outer surface of the bearing seat 2; an inclined seat 13 is fixedly connected to one end of the elastic compression column 12 near the mold frame; a pressing rod 14 is fixedly connected to the outer surface of the telescopic end of the cylinder frame 3; the pressing rod 14 and the inclined seat 13 are arranged on the same plane; a fixing rod 15 is fixedly connected to the outer surface of the inclined seat 13; two fixing rods 15 are provided and are fixedly connected to the outer surfaces of the front mold frame and the rear mold frame respectively;

[0049] During operation, as the telescopic end of the cylinder frame 3 moves, it simultaneously drives the pressing rod 14 to move. During the movement, the pressing rod 14 comes into contact with and presses against the inclined surface of the inclined seat 13, causing the inclined seat 13 to compress the elastic compression column 12. The inclined seat 13 then drives the fixed rod 15 to move a certain distance. Subsequently, the fixed rods 15 at different positions will drive the front mold frame and the rear mold frame to move away from each other. Therefore, the upper mold frame, front mold frame, rear mold frame, left mold frame, and right mold frame of the mold frame 1 will move away from the lamp housing mold, exposing the lamp housing mold to the outside. As a result, each side of the lamp housing mold is flat, avoiding scratches on its outer surface and improving the forming rate of the lamp housing mold.

[0050] The shape of the pressure rod 14 near the inclined seat 13 is arc-shaped, which is conducive to the pressure of the pressure rod 14 on the inclined seat 13, so that the inclined seat 13 can move a certain distance; the outer surface of the elastic compression column 12 is fixedly connected with a compression spring, which can facilitate the recovery of the elastic compression column 12 when it is not compressed.

[0051] Each of the mold frames has symmetrically arranged embedded rods slidably connected to its outer surface; each of the mold frames has an electric rod 161 fixedly connected to its outer surface; the top end of the electric rod 161 is connected to the lower surface of the embedded rod 16; a pressure frame 17 is rotatably connected to the outer surface of the embedded rod 16; a scraper 18 is rotatably connected to the outer surface of the pressure frame 17; and a rotating column adapted to the pressure frame 17 is provided on the outer surface of the embedded rod 16.

[0052] During operation, after the lamp housing mold is removed, the mold frames are separated from each other. The operator can manually rotate the pressing frame 17, causing the pressing frame 17 to drive the scraper 18 to press against the inner side of the mold frame. Then, the electric rod 161 is driven, causing the electric rod 161 to move the embedded rod 16. The embedded rod 16 then drives the scraper 18 to move along the inner side of the mold frame, so that the scraper 18 can process the mold waste on the inner surface of the mold frame, thus automatically cleaning up the waste.

[0053] A plurality of elastic rods 19 are fixedly connected to the outer surface of the pressure frame 17; the plurality of elastic rods 19 are arranged at equal intervals on the outer surface of the pressure frame 17; the side of each elastic rod 19 away from the pressure frame 17 is fixedly connected to the outer surface of the scraper 18;

[0054] During operation, multiple elastic rods 19 are provided. These elastic rods 19 can press against the outer surface of the scraper 18, so that the scraper 18 is pressed tightly against the inner surface of the mold frame, which facilitates the scraper 18 to scrape the waste material on the inner surface of the mold.

[0055] Each mold frame has a sliding groove on its outer surface that is adapted to the embedded rod 16; one end of the embedded rod 16 is slidably connected inside the sliding groove; the sliding groove adapted to the embedded rod 16 is provided to help maintain the embedded rod 16 moving along the axis and facilitate the scraping of waste material by the scraper rod 18.

[0056] Example 2

[0057] like Figure 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the outer surface of the bearing seat 2 is provided with a circular groove 20 that is adapted to the elastic compression column 12; one end of the elastic compression column 12 passes through the interior of the circular groove 20; the circular groove 20 is provided to facilitate the movement of the elastic compression column 12 and facilitate the removal of the front and rear mold frames.

[0058] During operation, in the initial state, the upper mold frame, lower mold frame, front mold frame, rear mold frame, left mold frame, and right mold frame are all joined together to form a sealed cavity. The first frame 101 and the second frame 102 above are also joined together to form the upper injection port. Molding liquid is injected into the sealed cavity through the injection port, gradually forming the lamp housing mold. When the lamp housing mold has cooled and solidified after a certain period, and needs to be removed, the telescopic end of the externally controlled cylinder frame 3 moves, causing the telescopic end to drive the left and right mold frames. The left and right mold frames move away from the lamp housing mold, separating from it and no longer adhering to it. Then, the lower mold frame is pushed upward by the telescopic cylinder 4, causing it to eject the lamp housing mold. Finally, the worker can remove it. This invention divides the mold frame 1 into multiple mold frames, which can be removed one by one, thus facilitating the ejection of the lamp housing mold. It also solves the problem in the prior art where some ejection mechanisms are in direct contact with the lamp housing mold, causing scratches on the mold side surface, and reduces the defect rate during lamp housing processing.

[0059] When the telescopic ends of the cylinder frame 3 drive the left mold frame and the right mold frame to move away from each other, the telescopic ends will simultaneously drive the support frame 5 on the upper surface to move. The support frame 5 drives the connecting frame 6 to move. Since the connecting wheel 61 at one end of the connecting frame 6 presses against the lower surface of the arc seat 8, when the connecting frame 6 and the connecting wheel 61 move, the connecting wheel 61 will press against the telescopic spring 81 along the lower surface of the arc seat 8, causing the arc seat 8 to drive the column rod 7 to move. The column rod 7 at different positions will drive the first frame 101 and the second frame 102 to move, so that the first frame 101 and the second frame 102 move away from the upper surface of the lamp housing mold. At this time, the mold frames on the upper, left and right sides of the mold are away from the mold surface, so that the mold frames no longer stick to the mold, which is more conducive to the removal of the lamp housing mold and avoids scratches on the upper surface of the mold when the upper mold frames are removed.

[0060] An arc-shaped groove 9 is formed on the surface of the arc-shaped seat 8, which facilitates the limiting of the connecting wheel 61, allowing the connecting wheel 61 to roll inside the arc-shaped groove 9. This facilitates the lifting of the arc-shaped seat 8 by the connecting wheel 61, thereby facilitating the ejection of the first frame 101 and the second frame 102. A limiting groove 10 and a limiting post 11 are provided to limit the movement of the first frame 101 and the second frame 102, preventing them from shifting during movement. When the telescopic end of the cylinder frame 3 moves, its telescopic end will simultaneously drive the pressing rod 1. 4. During the movement, the pressing rod 14 will contact and press against the inclined surface of the inclined seat 13, causing the inclined seat 13 to compress the elastic compression column 12. The inclined seat 13 will drive the fixed rod 15 to move a certain distance. Then, the fixed rods 15 at different positions will drive the front mold frame and the rear mold frame to move away from each other. Therefore, the upper mold frame, front mold frame, rear mold frame, left mold frame and right mold frame of the mold frame 1 will move away from the lamp housing mold, so that the lamp housing mold is exposed to the outside. Thus, each side of the lamp housing mold is flat, avoiding the problem of scratches on its outer surface and improving the forming rate of the lamp housing mold.

[0061] After the lamp housing mold is removed, the mold frames are separated. The operator can manually rotate the pressing frame 17, causing the pressing frame 17 to drive the scraper 18 to press against the inner side of the mold frame. Then, the electric rod 161 is driven, causing the electric rod 161 to move the embedded rod 16. The embedded rod 16 then drives the scraper 18 to move along the inner side of the mold frame, allowing the scraper 18 to process the mold waste on the inner surface of the mold frame, thus automatically cleaning the waste. Multiple elastic rods 19 are provided, which can press against the outer surface of the scraper 18, so that the scraper 18 is tightly pressed against the inner surface of the mold frame, which facilitates the scraper 18 to remove the waste from the inner surface of the mold. A sliding groove adapted to the embedded rod 16 is provided, which helps to keep the embedded rod 16 moving along the axis, facilitating the scraper 18 to remove the waste.
