Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamp cover production, and particularly relates to a forming die for a front car lamp cover. Background Art

[0002] Injection molding is a processing method used in mass-producing some parts with complex shapes. Specifically, it refers to injecting the heat-melted material into the mold cavity, and after cooling and solidifying, the formed product is obtained. An injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. When injection molding, the moving mold and the fixed mold are closed to form the gating system and the cavity, and when the mold is opened, the moving mold and the fixed mold are separated to take out the plastic product.

[0003] When producing automobile lamp covers, injection molds are usually required. However, the natural cooling speed of existing injection molds is relatively slow, and single air cooling or liquid cooling cannot effectively cool the injection material in the forming mold in a short time, thus affecting the shape of the material during the separation process. Summary of the Invention

[0004] The purpose of the utility model is to provide a forming die for a front car lamp cover to solve the above-mentioned defects in the prior art.

[0005] A forming die for a front car lamp cover includes a mold support. One side of the mold support is provided with a liquid storage water tank. The top end of the liquid storage water tank is provided with an input end of a circulation pump. The top end of the liquid storage water tank is connected through a drain check valve. One side of the drain check valve is provided with a cooling mechanism, and the cooling mechanism performs circulating water cooling operation on the mold, thereby shortening the time of the liquid during the cooling process. One side of the mold support is provided with a shaping mechanism, and the shaping mechanism performs shaping treatment on the material during the injection molding process, thereby producing lamp covers of different sizes.

[0006] Preferably, the shaping mechanism includes an electric cylinder, an upper mold base, shaping modules, a lower mold base, and shaping grooves. The electric cylinder is installed on one side of the mold support. The output end of the electric cylinder is connected to the upper mold base. The lower end of the upper mold base is equidistantly provided with shaping modules. The lower mold base is arranged directly below the shaping modules. The top end of the lower mold base is equidistantly provided with shaping grooves.

[0007] Preferably, the lower mold base is connected to the output end of the circulation pump through an internally provided heat absorption cavity.

[0008] Preferably, the cooling mechanism includes a liquid storage water tank, a wind box, a motor, a semiconductor refrigeration chip, and mixing blades. The motor is installed on one side of the wind box. One side of the wind box is provided with a liquid storage water tank. The semiconductor refrigeration chips are symmetrically arranged inside the liquid storage water tank. The mixing blades are axially connected inside the liquid storage water tank.

[0009] Preferably, the liquid storage water tank is connected to the output end of the motor through the mixing blades arranged inside.

[0010] Preferably, the liquid storage water tank and the heat absorption cavity form a circulation mechanism through the circulation pump and the drain check valve arranged at the top end.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. During use, multiple shaping modules with the same size are installed at the bottom end of the upper mold base, so that the shaping modules are inserted into the shaping grooves. Then, the heat absorption cavity absorbs the heat of the injection molding material. Then, by injecting circulating liquid, the circulating liquid takes away the heat of the injection molding material. By using the mixing blades, the flow rate of the liquid is accelerated, and the inhaled liquid is cooled by the semi-circular semiconductor refrigeration sheet. Then, the liquid is pumped into the heat absorption cavity again by the circulation pump.

[0013] 2. When the motor drives the mixing blades to rotate, the motor drives the fan blades in the air box to rotate, thereby accelerating the flow rate of the air through the rotating fan blades, further accelerating the flow rate of the air in the lower mold base, and thus shortening the cooling time of the mold.

[0021] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figures 1 to 5 shown, a forming mold for a vehicle headlamp cover includes a mold support 1. A liquid storage water tank 10 is provided on one side of the mold support 1. The input end of a circulation pump 8 is provided at the top of the liquid storage water tank 10. A liquid discharge one-way valve 9 is connected through the top of the liquid storage water tank 10. A cooling mechanism 11 is provided on one side of the liquid discharge one-way valve 9. The cooling mechanism 11 performs circulating water cooling operation on the mold, thereby shortening the time of the liquid during the cooling process. A shaping mechanism 7 is provided on one side of the mold support 1. The shaping mechanism 7 performs shaping treatment on the material during the injection molding process, thereby producing lamp covers of different sizes.

[0023] In this embodiment, the shaping mechanism 7 includes an electric cylinder 2, an upper mold base 3, shaping modules 4, a lower mold base 5 and shaping grooves 6. The electric cylinder 2 is installed on one side of the mold support 1. The output end of the electric cylinder 2 is connected to the upper mold base 3. The shaping modules 4 are equidistantly arranged at the bottom end of the upper mold base 3. The lower mold base 5 is provided directly below the shaping modules 4. The shaping grooves 6 are equidistantly opened at the top end of the lower mold base 5. By inserting the shaping modules 4 into the shaping grooves 6, the lower mold base 5 takes away the heat of the material.

[0024] In this embodiment, the lower mold base 5 is connected to the output end of the circulation pump 8 through an internal heat absorption cavity 16. The heat absorption cavity 16 cools the material inside the shaping grooves 6 to prevent poor shaping stability of the material caused by excessive heat.

[0025] In this embodiment, the cooling mechanism 11 includes a liquid storage water tank 10, an air box 12, a motor 13, a semiconductor refrigeration sheet 14 and a mixing blade 15. The motor 13 is installed on one side of the air box 12. The liquid storage water tank 10 is provided on one side of the air box 12. The semiconductor refrigeration sheets 14 are symmetrically arranged inside the liquid storage water tank 10. A mixing blade 15 is rotationally connected inside the liquid storage water tank 10. By driving the mixing blade 15 to rotate by the motor 13 and simultaneously rotating the blades inside the air box 12, the lower mold base 5 is assisted in cooling by air cooling.

[0026] In this embodiment, the liquid storage water tank 10 is connected to the output end of the motor 13 through the mixing blade 15 provided inside. The mixing blade 15 accelerates the flow of the liquid and the contact area between the semiconductor refrigeration sheet 14 and the liquid, shortening the liquid cooling time.

[0027] In this embodiment, the liquid storage water tank 10 and the heat absorption cavity 16 form a circulation mechanism through the circulation pump 8 and the drain check valve 9 provided at the top. The liquid is continuously circulated and injected through the circulation pump 8, and then after the liquid is cooled, it is injected into the heat absorption cavity 16 again.

[0028] When this vehicle headlamp molding die is actually applied, it includes the following working contents:

[0029] Step 1: The operator installs the circulation pump 8 and the drain check valve 9 on one side of the shaping module 4, installs the circulation pump 8 and the drain check valve 9 on the top of the liquid storage water tank 10, and directly introduces the liquid into the inside of the liquid storage water tank 10 and the heat absorption cavity 16. The operator drives the upper mold base 3 and the shaping module 4 to move vertically downward through the electric cylinder 2, so that the shaping module 4 is inserted into the shaping groove 6 provided below, and then the melted material is injected into the shaping groove 6 through the injection pump.

[0030] Step 2: During the shaping process of the material, by turning on the motor 13, the fan blades in the air box 12 are driven to rotate by the motor 13. The flow rate of the air is accelerated by the fan blades in the air box 12, and the bottom end of the lower mold base 5 is subjected to circulating cooling treatment. Then, by turning on the circulation pump 8, the liquid inside the liquid storage water tank 10 is pumped out by the circulation pump 8, and the liquid is injected into the heat absorption cavity 16. The injection molding material is cooled by the circulating liquid.

[0031] Step 3: When the liquid is injected into the heat absorption cavity 16, at the same time, the mixing liquid blades 15 are driven to rotate by the motor 13. The speed of the liquid circulation is accelerated through the mixing liquid blades 15, and the liquid is cooled by the semiconductor refrigeration sheet 14. The cooled liquid is continuously injected into the heat absorption cavity 16 through the circulation pump 8, and the heat-absorbed liquid inside the heat absorption cavity 16 is directly discharged through the drain check valve 9, thereby completing the refrigeration and circulation process of the liquid.

[0032] Step 4: Then, the electric cylinder 2 is turned on again, and the upper mold base 3 and the shaping module 4 are driven to move vertically upward by the electric cylinder 2, so that the shaping module 4 moves out of the shaping groove 6. The product is ejected from the mold cavity by the ejection system and leaves the mold. The drain check valve 9 and the circulation pump 8 can be closed. After the injection molding material is taken out, the upper mold base 3 and the lower mold base 5 are then docked.

[0033] Therefore, the above disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
