Description

Technical Field

[0001] The present invention belongs to the technical field related to lamp housing moulds, and more specifically, particularly relates to an integrated injection mould for producing automobile lamp housings. Background Art

[0002] With the development of economy, people's requirements for travel quality are increasing, and the total demand for automobiles is increasing. Lamp housing is an indispensable part of automobiles. The requirements for molds for producing lamp housings in production workshops are also increasing. The quality of the mold will directly affect the appearance and quality of the subsequent lamp housings. However, the lamp housing molds in the prior art have the following defects:

[0003] In the prior art, after the lamp housing has cooled, it is necessary to eject the lamp housing. After multiple ejection processes, the ejector rod will be worn to varying degrees. When wear occurs, during the process of ejecting the lamp housing, the worn area will damage the surface of the lamp housing, thereby affecting the appearance and quality of the mold. The process of workers replacing the ejector rod during polishing is time-consuming and affects production.

[0004] In the prior art, during the ejection process of the lamp housing, there is a small amount of relative movement between the ejector rod and the lamp housing, which will generate friction, and the ejector rod needs to exert a certain pressure to eject the lamp housing from the mold. This pressure will aggravate the friction. When the contact area between the lamp housing and the ejector rod is small or the surface roughness of the ejector rod is large, the friction force per unit area will increase, which is not conducive to the relative sliding between the lamp housing and the ejector rod, and will cause scratches to appear at the contact part between the lamp housing and the ejector rod, resulting in failure of product quality inspection and affecting output efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Through the operation of the hydraulic pushing device, the push plate is driven to slide, and the push plate pushes the threaded rod to slide, and the threaded rod slides in the toothed threaded sleeve.

During rotation, since a plurality of grinding tools are arranged in the grinding cylinder, the grinding tools will grind the surface of the push rod to ensure the smoothness of the surface of the push rod.

[0020] The integrated injection mold for producing automobile lamp housings of the present invention has a grinding cylinder that drives the ring to rotate during grinding, and the fan blades generate gas flow during rotation. The external gas enters the second cavity through the gas flow port provided on the mounting plate, blows the debris in the second cavity, and at the same time, the debris enters the debris channel through the debris passing port on the push rod, and then is discharged to the outside. At the same time, with the increase of gas, the heat dissipation effect of the push rod during grinding is also improved, thereby improving the grinding efficiency, further ensuring the ejection efficiency, and better improving the production efficiency.

[0048] Preferably, a plurality of connecting rods 13 are arranged between the movable table plate 20 and the fixed table plate 21, a locking mechanism 14 is arranged on the side of the movable table plate 20 away from the template 15, the locking mechanism 14 drives the movable table plate 20 to move, a first hydraulic device 16 is arranged on the side of the locking mechanism 14, the first hydraulic device 16 drives the locking mechanism 14 to operate so that the core plate 27 and the cavity plate 28 are close to each other and locked, a second hydraulic device 17 is arranged on the side of the fixed table plate 21 away from the template 15, the second hydraulic device 17 supports the fixed table plate 21 to maintain its position, a protective shell 19 is sleeved on the outer side of the first hydraulic device 16, the protective shell 19 is fixedly mounted on the base 54, and a control device 18 is fixedly mounted on the base 54.

[0049] Specific use of the present invention:

[0050] When in use, the control device 18 controls the start of the first hydraulic device 16, and the first hydraulic device 16 drives the locking mechanism 14 to move. The locking mechanism 14 will push the movable platen 20 to move when moving, until the cavity plate 28 and the core plate 27 are abutted against each other, and then stop and lock, so that a lamp housing forming cavity 30 is formed between the cavity plate 28 and the core plate 27, and then the control device 18 controls the valve in the hopper 11 to open, and the plastic liquid in the hopper 11 will pass through the barrel 12 and then be sprayed into the lamp housing forming cavity 30 by the nozzle 24, and the plastic liquid will be cooled and formed in the lamp housing forming cavity 30, thereby completing the production of the lamp housing of the vehicle lamp.

[0051] During demoulding, the hydraulic pushing device 53 drives the push plate 23 to slide, and the push plate 23 drives the push rod 22 and the threaded rod 26 to slide. The threaded rod 26 slides in the toothed threaded sleeve 36. When sliding, it drives multiple toothed threaded sleeves 36 to rotate. Since the second convex teeth 55 and the first convex teeth 43 are meshed with each other, the toothed threaded sleeve 36 drives the toothed cylinder 33 to rotate while rotating. When the toothed cylinder 33 rotates, the grinding cylinder 32 also rotates accordingly. During rotation, since multiple grinding tools 34 are arranged in the grinding cylinder 32, the grinding tools 34 will grind the surface of the push rod 22 to ensure the smoothness of the surface of the push rod 22. At the same time, since the second cavity 40 is eccentrically arranged, during grinding, the second cavity 40 in the grinding cylinder 32 will discharge the debris generated by grinding. At the same time, since the toothed cylinder 33 and the push rod 22 are concentric The setting will ensure that the grinding tool 34 grinds all parts of the surface of the push rod 22 during rotation. Since a plurality of grinding tools 34 are arranged in the grinding cylinder, the distance between the grinding tool 34 and the push rod 22 gradually decreases. The grinding tool 34 with a large distance will first cut off the impurities on the push rod 22, and then the grinding tool 34 with a small distance will cut off the impurities on the push rod 22 again, forming a sequential cutting effect. When facing a thick magazine to be cut, the extrusion force between the grinding tool 34 and the push rod 22 can be reduced by layered cutting, thereby reducing the wear of the grinding tool 34 and increasing the number of uses. In addition, the extrusion force on the push rod 22 is controlled within a small range, thereby reducing the adverse effects of the grinding process on the push rod 22, so as to avoid the push rod 22 being subjected to a large extrusion force and causing itself to deform.

[0052] At the same time, when the toothed cylinder 33 rotates, the arc-shaped grinding tool 47 pops out and grinds the smooth surface of the end of the push rod 22, so as to better ensure the smooth surface of the push rod 22 and ensure that the surface of the lamp housing will not be affected by the push rod 22 when the mold is in the process of ejecting the lamp housing. The appearance and quality of the lamp housing surface will not be affected by the push rod 22, and the cost will not be increased due to damage to the lamp housing after cooling and molding. At the same time, the production efficiency of the lamp housing is improved, and the push rod 22 continues to extend outward to resist the sliding plate 51. The sliding plate 51 slides into the fifth cavity 48 to open the passage of the push rod 22, and the push rod 22 ejects the lamp housing from the mold.

[0053] At the same time, during grinding, the grinding cylinder 32 will drive the ring 38 to rotate. During the rotation, the fan blades 39 will generate gas flow. The external gas enters the second cavity 40 through the gas flow port 52 set on the mounting plate 56, and blows the debris in the second cavity 40. At the same time, the debris enters the debris channel 31 through the debris passing port on the push rod 22, and then is discharged to the outside, so as to avoid the debris generated by grinding from affecting the push rod 22, and better ensure the smoothness of the surface of the push rod 22. At the same time, with the increase of gas, the heat dissipation effect of the push rod 22 during grinding is also improved, thereby improving the grinding efficiency, further ensuring the ejection efficiency, and better improving the production efficiency.

[0054] After ejection and demolding, the push rod 22 retracts inward, and the sliding plate 51 slides on the surface of the push rod 22. When sliding to the end of the push rod 22, the material remaining at the end of the push rod 22 will be cut and scraped off to prevent the material on the lamp housing from adhering to the push rod 22 after the ejection process, which will affect the next ejection.

[0055] At the same time, the grinding process will grind the push rod 22 once when the push rod 22 is extended, and the grinding process will grind the push rod 22 twice when the push rod 22 is retracted, so as to always keep the smoothness of the push rod 22, ensure the ejection effect, and improve the production efficiency.

[0056] At the same time, the fixing block 35 will push the debris to move, ensuring the discharge of the debris, and at the same time, the wiping block 37 wipes the surface of the push rod 22 to further improve the smoothness of the surface of the push rod 22.

[0057] like Fig. 9 As shown, since the grinding cylinder 32 is eccentrically arranged relative to the push rod 22, during grinding, the grinding cylinder 32 rotates around the axis of the push rod 22, and one side of the inner wall of the grinding cylinder 32 will be close to the outer peripheral surface of the push rod 22, and the other side will be away from the outer peripheral surface of the push rod 22. A larger space will appear on the side away from the push rod 22, and debris will escape into this space, thereby achieving all-round cleaning of the outer peripheral surface of the push rod 22 by the grinding cylinder 32 while enhancing the chip removal effect, reducing the risk of chip jamming, and helping to improve the surface quality of grinding.

[0058] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
