Description

Technical Field

[0001] The utility model relates to the technical field of injection molding vehicle lamp molds, in particular to an injection molding vehicle lamp mold which can be automatically cooled. Background Art

[0002] Headlights are a common automotive accessory. They are used to illuminate the road at night and to send out various driving signals. They are generally divided into headlights, taillights, turn signals, etc. The combined headlights are located at the front of the car and they mainly serve as lighting and signaling. The light emitted by the headlights can illuminate the road conditions in front of the car, allowing the driver to drive safely at night. The external lampshade is generally injection molded by a special mold during the production process.

[0003] The existing patent technology CN202022143284.3 proposes that the movable mold seat is made of metal as a whole, so its own weight is very heavy. After a long time, it will be easy to slightly bend the four movable guide pillars, which will cause the movable guide pillars to deform, which will affect the fitting integrity between the two mold seats. Based on this, a fast cooling type injection molding headlight mold is proposed, which can roll on the base through nine stable rollers, so as not to hinder the normal molding operation of the movable mold seat, and at the same time, it can also prevent the four movable guide pillars from being deformed due to the long-term influence of the weight of the movable mold seat. However, after the injection molding of the product raw material, the injection molding headlight mold still has a shaping step, which requires waiting for the injection molding raw material in the molding cavity to cool and shape, and finally form the product. However, the injection molding headlight mold does not have an auxiliary cooling and molding mechanism, and relies on the natural cooling of the product to complete, so that the efficiency of product shaping still needs to be improved. For this reason, we designed an automatic cooling injection molding headlight mold to solve the above problems. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides an injection molding vehicle lamp mold capable of automatic cooling, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: an automatically cooled injection molding headlight mold, comprising a fixed seat, a top plate and a movable platform, wherein evenly distributed guide rods are connected between the fixed seat and the top plate, and the movable platform is slidably sleeved on the outside of the guide rods, and an electric telescopic rod is fixedly sleeved on the middle part of the top plate, and a driving rod of the electric telescopic rod is fixedly connected to the movable platform, a lower mold groove is provided in the fixed seat, an upper mold corresponding to the position of the lower mold groove is sleeved on the movable platform, and a cold air unit is connected to the outside of the movable platform, a cavity is provided in the upper mold, and the upper mold and the cold air unit are connected through a No. 2 connecting pipe, an injection molding tube connected to the lower mold groove is sleeved on the outside of the fixed seat, and a cooling cavity located on the outside of the lower mold groove is provided in the fixed seat.

[0006] Furthermore, the lower mold groove and the upper mold match each other, and the lower mold groove and the upper mold can form an injection cavity, and the movable table is provided with an exhaust hole matching the injection cavity.

[0007] Furthermore, the No. 2 connecting pipe extends to the inner side of the upper mold, and the upper mold is provided with evenly distributed heat conducting plates.

[0008] Furthermore, a discharge hole extending to the top of the movable table is formed at the top of the upper mold, and a discharge hole communicating with the cooling cavity is formed at the outside of the fixing seat.

[0009] Furthermore, two groups of No. 1 connecting pipes that are symmetrically distributed are connected in the cooling chamber, a sleeve pipe is sleeved on the No. 1 connecting pipe, and a butt pipe matching the sleeve pipe is connected below the cold air unit.

[0010] Furthermore, a sealing ring is sleeved on the top end of the sleeve pipe, and the inner diameter of the sealing ring is smaller than the outer diameter of the butt pipe.

[0011] Furthermore, the cross section of the cooling cavity is U-shaped, and the cooling cavity is entirely wrapped around the outer side of the lower mold groove.

[0012] The utility model provides an automatic cooling injection lamp mold, which has the following beneficial effects:

[0013] 1. The automatically cooled injection lamp mold, through the coordinated use of No. 1 connecting pipe and cooling cavity as well as No. 2 connecting pipe and cooling air unit, enables the automatically cooled injection lamp mold to open a cooling cavity located outside the lower mold groove in the fixed seat, and open a cavity inside the upper mold. The cold air prepared by the cooling air unit can be injected into the cooling cavity and the interior of the upper mold through the No. 1 connecting pipe and the No. 2 connecting pipe respectively, so that the temperature of the outside of the upper mold and the outside of the lower mold groove is reduced, which promotes the shaping of the injection lamp product between the upper mold and the lower mold groove, and effectively improves the molding efficiency of the injection lamp mold product after injection.

[0014] 2. The automatically cooled injection molding headlight mold uses a cold air unit and a butt joint as well as a No. 1 connecting pipe and a sleeve pipe in coordination, so that when the movable table is moved to the top of the fixed seat, the lower mold groove cooperates with the upper mold to form an injection cavity, and at the same time, the butt joint pipe below the cold air unit is docked with the sleeve pipe on the No. 1 connecting pipe, and the connection is sealed by the sealing ring. When the product is cooled and finalized, the cold air prepared by the cold air unit can be output through the No. 2 connecting pipe and the butt joint, and at the same time, the temperature of the outer side of the lower mold groove and the outer side of the upper mold is reduced, so that the automatically cooled injection molding headlight mold can reduce the cooling area on the two sets of molds at the same time through a single refrigeration device, thereby reducing the production cost.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figures 1 to 4The utility model provides a technical solution: an automatically cooled injection lamp mold, comprising a fixed seat 1, a top plate 2 and a movable platform 5, evenly distributed guide rods 3 are connected between the fixed seat 1 and the top plate 2, the movable platform 5 is slidably sleeved on the outside of the guide rods 3, an electric telescopic rod 4 is fixedly sleeved on the middle part of the top plate 2, a driving rod of the electric telescopic rod 4 is fixedly connected to the movable platform 5, and the electric telescopic rod 4 can drive the movable platform 5 to move along the guide of the guide rod 3 as a whole through its driving shaft when working.

[0023] A lower mold groove 7 is provided in the fixed seat 1, and an upper mold 11 corresponding to the position of the lower mold groove 7 is mounted on the movable platform 5, and a cooling air unit 6 is connected to the outer side of the movable platform 5. The lower mold groove 7 and the upper mold 11 match each other, and the lower mold groove 7 and the upper mold 11 can form an injection cavity. When the movable platform 5 moves to the top of the fixed seat 1, the lower mold groove 7 can cooperate with the upper mold 11 to form an injection cavity, and injection raw materials can be injected into the injection cavity through the injection tube 9. An exhaust hole matching the injection cavity is provided on the movable platform 5, and the gas in the cavity is discharged through the exhaust hole until the raw material fills the injection cavity. A cavity is provided in the upper mold 11, and the upper mold 11 is connected to the cooling air unit 6 through a No. 2 connecting pipe 12.

[0024] The No. 2 connecting pipe 12 extends to the inner side of the upper mold 11, and the cold air prepared by the cold air unit 6 can be output through the No. 2 connecting pipe 12. The upper mold 11 is provided with evenly distributed heat conducting plates 15. The cold air transported in the No. 2 connecting pipe 12 is passed into the upper mold 11, and the temperature outside the upper mold 11 is quickly reduced under the action of the heat conducting plates 15. The top of the upper mold 11 is provided with a discharge hole extending to the top of the movable table 5. The discharge hole at the top of the upper mold 11 can facilitate the discharge of the cold air passed into the upper mold 11.

[0025] See also Figures 2 to 5 The outside of the fixed seat 1 is provided with a discharge hole connected to the cooling cavity 13, and the discharge hole on the outside of the fixed seat 1 can facilitate the discharge of the cold air introduced into the cooling cavity 13. The cross-section of the cooling cavity 13 is U-shaped. The U-shaped structure of the cooling cavity 13 can ensure the wrapping effect of the cooling cavity 13 on the outside of the lower mold groove 7, and the cooling cavity 13 is wrapped around the outside of the lower mold groove 7 as a whole, so that when the internal temperature of the cooling cavity 13 drops, the temperature in the lower mold groove 7 can be effectively reduced. The outside of the fixed seat 1 is provided with an injection tube 9 connected to the lower mold groove 7, and the fixed seat 1 is provided with a cooling cavity 13 located on the outside of the lower mold groove 7. Two groups of No. 1 connecting pipes 8 are symmetrically distributed and connected to the cooling cavity 13. When the movable platform 5 moves to the top of the fixed seat 1, the docking pipe 14 under the cooling air unit 6 docks with the sleeve pipe 10 on the No. 1 connecting pipe 8.

[0026] A sleeve tube 10 is sleeved on the No. 1 connecting pipe 8, and a docking tube 14 matching the sleeve tube 10 is connected to the bottom of the cold air unit 6, so that a channel is formed between the cold air unit 6 and the cooling chamber 13, which is convenient for passing cold air into the cooling chamber 13. The cold air unit 6 is electrically connected to the injection molding equipment and can be automatically started after the injection molding is completed. A sealing ring 16 is sleeved on the top of the sleeve tube 10. During the docking process between the docking tube 14 and the sleeve tube 10, the outside of the docking tube 14 can squeeze the sealing ring 16, causing the sealing ring 16 to deform. The inner diameter value of the sealing ring 16 is smaller than the outer diameter value of the docking tube 14. After the docking tube 14 and the sleeve tube 10 are connected, the sealing ring 16 can close the gap at the connection to ensure the connection effect.

[0027] In summary, when the automatic cooling injection molding headlight mold is used, the electric telescopic rod 4 works and drives the movable platform 5 to move along the guide of the guide rod 3 through its driving shaft. When the movable platform 5 is moved to the top of the fixed seat 1, the lower mold groove 7 cooperates with the upper mold 11 to form an injection molding cavity. At the same time, the butt joint 14 below the cooling air unit 6 is butted with the sleeve pipe 10 on the No. 1 connecting pipe 8. The connection is sealed under the action of the sealing ring 16. The injection molding raw material is injected into the injection molding cavity through the injection molding pipe 9. After the raw material fills the injection molding cavity, the cooling air unit 6 works and assists in the cooling and shaping of the product. The cold air prepared by the cooling air unit 6 can be respectively passed through the No. 2 connecting pipe 8 and the No. 3 connecting pipe 8. The connecting pipe 12 and the butt pipe 14 are output, the cold air transported in the No. 2 connecting pipe 12 is passed into the upper mold 11, and the temperature of the outer part of the upper mold 11 is quickly reduced under the action of the heat conductive sheet 15, and the cold air output from the butt pipe 14 enters the cooling chamber 13 through the sleeve pipe 10 and the No. 1 connecting pipe 8, and at the same time reduces the temperature of the outer side of the lower mold groove 7 and the outer part of the upper mold 11, and the cold air in the cooling chamber 13 and the upper mold 11 is discharged through the discharge hole until the product in the injection molding cavity is completely cooled and shaped, the electric telescopic rod 4 works again and drives the movable table 5 to reset, and the working process of the entire automatic cooling injection lamp mold is completed.
