Description

[Technical field]

[0001] The utility model relates to the technical field of automobile parts processing, in particular to the technical field of a cooling structure used for the production of an engine heat insulation cover. [Background technology]

[0002] The diesel engine heat shield is an important automotive component. Its main function is to insulate, protect the engine and other ancillary equipment from high temperature, and ensure the normal operation of the engine. The engine heat shield is usually made of metal and has good thermal insulation performance. It can effectively reduce the impact of engine high temperature on the surrounding environment and other components, which can not only extend the life of the engine, but also improve the overall performance and fuel economy of the car. In addition to the thermal insulation effect, the engine heat shield can also effectively block the invasion of dust, water vapor and other impurities, and reduce the possibility of the engine being affected by the external environment. This is very important for protecting the normal operation of the internal components of the engine and extending its service life. In general, the engine heat shield plays an indispensable role in automobile manufacturing. In addition to meeting basic thermal insulation protection needs, it can also improve the overall performance and aesthetics of the car.

[0003] Existing automobile engine heat shields are usually formed by hot pressing with sound-absorbing cotton, and the formed engine heat shield needs to be cooled after being taken out from the hot pressing mold. Among them, the engine heat shield taken out from the hot pressing mold cavity is usually directly placed on a work station or a material rack for cooling. On the one hand, the long cooling time affects the production efficiency. On the other hand, the materials used in various parts of the engine heat shield are uneven and the shapes are different. There is a situation where the cooling shrinkage is uneven and causes deformation, and the non-woven fabric covering the surface of the engine heat shield is wrinkled.

[0004] In order to solve the problems raised in the background technology, publication number CN214606113U discloses a cooling tool for the production of engine heat shields. Through the heat dissipation holes at the bottom of the accommodating cavity, the air on the convex surface of the engine heat shield can be kept circulating to quickly dissipate heat. Moreover, the heat of the engine heat shield is guided out through the tool body, which has a higher cooling efficiency than placing the engine heat shield directly on a work station or a material rack. A ventilation cavity is provided in the middle of the tool body, and the heat dissipation holes are connected to the ventilation cavity. The ventilation cavity is provided with an exhaust port to facilitate the exhaust of the heat dissipation holes by a fan, thereby greatly improving the cooling efficiency of the engine heat shield. However, this structure still has the following shortcomings:

[0005] 1. Although the device is connected to the ventilation cavity through the heat dissipation holes and uses a fan to suck out the heat from the heat dissipation holes, the cooling form is relatively simple and the cooling speed is relatively slow, which affects the processing efficiency. [Contents of the utility model]

[0006] The purpose of the utility model is to solve the problems in the prior art and to propose a cooling structure for the production of engine heat shields, which can utilize the coordinated use of an air cooling mechanism and a water cooling mechanism to achieve rapid cooling of the engine heat shield, and the water cooling and air cooling cooperate with each other, thereby improving the processing efficiency.

[0007] To achieve the above-mentioned purpose, the utility model proposes a cooling structure for the production of engine heat insulation covers, including a workbench, legs, a base, a placement groove, a column, a top plate, an air cooling mechanism, a water cooling mechanism, and a control switch. The lower end of the workbench is provided with a plurality of legs, a base is provided in the middle of the upper end of the workbench, a placement groove matched with the engine heat insulation cover is opened on the upper end of the base, columns are provided at the four corners of the upper end of the base, a top plate is commonly provided at the upper ends of the columns, an air cooling mechanism is provided on the top plate, a water cooling mechanism matched with the air cooling mechanism is provided on the workbench, and the control switch is provided on the front side wall of the workbench.

[0008] Preferably, the inner bottom wall of the placement groove is provided with a plurality of heat dissipation holes, and the heat dissipation holes penetrate the base, the workbench and communicate with the outside.

[0009] Preferably, the air cooling mechanism includes a motor and a hair dryer, the motor is arranged in the upper middle part of the top plate, and the hair dryer is arranged in the lower middle part of the top plate, the output end of the motor passes through the top plate and is connected to the hair dryer, the input end of the motor is electrically connected to the control switch, and the air outlet of the hair dryer is facing the direction of the placement slot.

[0010] Preferably, a cooling cavity is provided inside the base, and the cooling cavity is arranged in a spiral shape.

[0011] Preferably, the water cooling mechanism includes a liquid storage tank, a liquid pump, a first liquid inlet pipe, and a first liquid outlet pipe. Cooling liquid is stored in the liquid storage tank. A liquid pump is provided on one side of the liquid storage tank. The input end of the liquid pump is connected to the liquid storage tank through the first liquid inlet pipe, and the output end of the liquid pump is connected to the first liquid outlet pipe. The first liquid outlet pipe passes through the interior of the base and is connected to the liquid inlet of the cooling chamber, and the liquid pump is electrically connected to the control switch.

[0012] Preferably, a circulation pump is arranged on the upper side of the workbench, the input end of the circulation pump is connected to a second liquid inlet pipe, the second liquid inlet pipe passes through the interior of the base and is connected to the liquid outlet of the cooling chamber, the output end of the circulation pump is connected to a second liquid outlet pipe, the second liquid outlet pipe is connected to the liquid storage tank, and the circulation pump is electrically connected to the control switch.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model can realize rapid cooling of the engine heat shield through the coordinated use of the air cooling mechanism and the water cooling mechanism. When the engine heat shield is taken out of the hot pressing mold and placed in the placement groove, the motor and the liquid extraction pump are started at the same time. The motor drives the hair dryer to rotate, and then the hair dryer discharges air in the direction of the placement groove to achieve the effect of air cooling. The liquid extraction pump extracts the coolant in the liquid storage tank through the first liquid inlet pipe, and transports the coolant to the cooling cavity through the first liquid outlet pipe, so that the coolant circulates in the cooling cavity, and then the engine heat shield in the placement groove achieves the effect of water cooling. The cooperation of water cooling and air cooling improves the processing efficiency, and the heat is further discharged by setting the heat dissipation holes, which solves the problem of relatively single cooling form and relatively slow cooling speed.

[0015] 2. The utility model can circulate the coolant through the coordinated use of the circulation pump, the second liquid inlet pipe and the second liquid outlet pipe. When the circulation pump is started, the circulation pump draws the coolant in the cooling chamber through the second liquid inlet pipe, and transports the coolant to the liquid storage tank through the second liquid outlet pipe, thereby realizing the effect of recycling, which not only saves resources but also improves processing efficiency.
