Description

Technical Field

[0001] The utility model relates to the technical field of automobile roof production, in particular to a vacuum pumping mechanism for rapid cooling of the roof. Background Technique

[0002] The most important component of automobile molds is the panel molds. In a broad sense, automobile molds are the general term for molds that manufacture all parts of an automobile. For example, stamping molds, injection molds, forging molds, casting wax molds, glass molds, etc.

[0003] The roof of an automobile is an important part of the automobile interior. It not only has a decorative function, but also has the functions of sound insulation and heat insulation. The structure of the roof is very simple. Generally, it is formed by hot pressing with a composite of polyurethane foam materials. High-end cars use more materials and the roof is thicker. It can block most of the noise and heat from the top of the automobile.

[0004] However, in the production process of some existing automobile roof production molds, they are usually shaped by manual pressing with a simple tooling. The products cool slowly and the shaping time is long, resulting in low efficiency and affecting the output. Moreover, the products shaped manually have poor consistency. Therefore, there are certain limitations.

[0005] Therefore, we urgently need to provide a vacuum pumping mechanism for rapid cooling of the roof. Content of the Utility Model

[0006] The purpose of the utility model is to provide a vacuum pumping mechanism for rapid cooling of the roof, so as to solve the problems in the above-mentioned background technique that in the production process of some existing automobile roof production molds, they are usually shaped by manual pressing with a simple tooling, the products cool slowly and the shaping time is long, resulting in low efficiency and affecting the output; moreover, the products shaped manually have poor consistency.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A vacuum pumping mechanism for rapid cooling of the roof, including a processing table and a column. The column is fixedly connected to the rear end of the upper surface of the processing table. A vacuum pumping device is arranged inside the processing table, and a heating device is arranged above the column.

[0008] The vacuum pumping device includes a vacuum pumping unit and a fixing unit.

[0009] The vacuum pumping unit includes an electric lifting rod, a mold, an air extraction hose, and a vacuum pump. The two electric lifting rods are respectively installed on the front and rear sides inside the processing table. The mold is fixedly connected to the top of the electric lifting rod. The air extraction hose is fixedly connected to the center of the bottom of the mold. The air extraction port of the vacuum pump is connected to the bottom of the air extraction hose.

[0010] A further improvement is that suction holes are respectively formed on the front and rear sides of the upper surface of the mold. A suction chamber is formed at the bottom of the two suction holes. The top of the air extraction hose is connected to the suction chamber. After the ceiling raw material plate is placed on the processing table, the electric lifting rod is started to push the mold to fit the lower surface of the raw material plate. At this time, the vacuum pump is started to quickly extract the air between the mold and the raw material plate through the air extraction hose, the suction chamber and the suction holes to form a vacuum, forcing the raw material plate to fit the surface of the mold, so as to quickly complete the processing and forming of the ceiling.

[0011] A further improvement is that a lifting chamber is formed inside the processing table. The vacuum extraction device is installed inside the lifting chamber. A ventilation port is formed on the left outer surface of the processing table. A dust-proof net is installed inside the ventilation port. The airflow interaction between the lifting chamber and the outside is realized through the ventilation port. The setting of the dust-proof net avoids external dust from entering the inside of the lifting chamber.

[0012] A further improvement is that the fixing unit includes an annular pressing block, connecting ear plates and electric telescopic rods. The annular pressing block is installed above the processing table. The two connecting ear plates are respectively fixedly connected to the left and right outer surfaces of the annular pressing block. The two electric telescopic rods are respectively installed on the left and right sides of the processing table, and their tops are connected to the connecting ear plates. The raw material plate is placed on the processing table, and then the electric telescopic rods are started to pull the annular pressing block down, so as to press and fix the raw material plate on the processing table, avoiding the movement of the raw material plate during vacuum extraction.

[0013] A further improvement is that the heating device includes a lifting motor, a transmission member, a heating box and electric heating rods. The lifting motor is installed on the top of the column. The transmission member is connected to the output end of the lifting motor. The heating box is fixedly connected to the front end of the transmission member. The electric heating rods are installed inside the heating box.

[0014] A further improvement is that a guiding sliding groove is formed on the front surface of the processing table. The transmission member is installed inside the guiding sliding groove. U-shaped through holes are arranged in an array at the bottom of the heating box. Before vacuum extraction, the lifting motor is started to drive the screw rod in the transmission member to rotate, so as to drive the threaded sliding table on the screw rod and the heating box at its front end to move downward along the guiding sliding groove to above the raw material plate. At this time, the electric heating rods inside the heating box are started, and the heat is dissipated to the raw material plate through the U-shaped through holes to heat and soften it, which is more beneficial to the vacuum extraction forming.

[0015] A further improvement is that an electric control box is installed on the top of the right outer surface of the processing table. The vacuum extraction device and the heating device are respectively electrically connected to the electric control box. The heating temperature of the heating box is controlled through the electric control box, and vacuum extraction is carried out through the vacuum pump.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. The vacuum pumping mechanism for rapid cooling of the ceiling places the raw material plate on the processing table, and then starts the electric telescopic rod to pull the annular pressing block downward, thereby pressing and fixing the raw material plate on the processing table to prevent the raw material plate from moving during vacuum pumping.

[0018] 2. The vacuum pumping mechanism for rapid cooling of the ceiling, before vacuum pumping, starts the lifting motor to drive the transmission member to rotate, thereby driving the heating box to move above the raw material plate. At this time, start the electric heating rod inside the heating box, and dissipate the heat to the raw material plate through the U-shaped through hole to heat and soften it, which is more conducive to the vacuum forming process.

[0019] 3. The vacuum pumping mechanism for rapid cooling of the ceiling starts the electric lifting rod to push the mold to fit the lower surface of the raw material plate. At this time, start the vacuum pump to quickly extract the air between the mold and the raw material plate through the air extraction hose, the air suction cavity and the air suction holes to form a vacuum, forcing the raw material plate to fit the surface of the mold, thereby quickly completing the processing and forming of the ceiling.
