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

1.  By setting a drawer plate at the bottom of the forming slot, the drawer plate can move inside the protective cover, and the gate opened at the top of the protective cover can be used to pour plastic material. The protective cover can effectively protect the operator, and the drawer plate can pass through the bottom two The slide rail at the end is movably connected to the bottom of the protective cover, so that the user can perform safe injection molding and take out the molded car door panel, and the exhaust fumes generated during the injection molding of the car door panel inside the protective cover are all sucked into the bottom by the smoking pipe. In the base to prevent people from inhaling smoke.
2. The utility model has a simple structure and a compact connection. By setting a reaction barrel inside the base, the reaction barrel is divided into three layers, the top water layer, the middle flue gas layer, the bottom activated carbon layer, and the flue gas collected in the flue gas layer to increase the reaction. The air pressure in the bucket causes the push plate to move upward to squeeze the water in the water layer into the outlet pipe, and then enters the cooling bucket at the bottom of the drawer plate to quickly cool the automobile door panel that is initially shaped in the forming tank, so that the door panel has high forming efficiency and smoke. After being gradually adsorbed by activated carbon, the air pressure in the reaction barrel dropped, the push plate moved down, and water entered the water layer again.

Detailed ways

In the following, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the implementation example. Based on the embodiments of the present invention, all other embodiments obtained by a person having ordinary skill in the art without making creative work belong to the protection scope of the present invention.

Example 1

Please refer to Fig. 1-5, a mold for an automobile door panel includes a bottom plate 1 and a forming groove 15, a protective cover 2 is provided on the top of the bottom plate 1, and a gate 3 is provided on the top of the protective cover 2. The protective cover 2 can prevent When high-temperature fluid splashes out of the molding tank 15, the user is burned. Smoking pipes 4 are provided on both sides of the protective cover 2, drawer plates 5 are provided inside the protective cover 2, slide rails 17 are provided at both ends of the bottom of the drawer plate 5, and drawers are provided. A cooling bucket 16 is provided below the plate 5, a slope bottom 18 is provided inside the cooling bucket 16, a molding groove 15 is provided on the top of the drawer plate 5, a base 8 is provided on the bottom of the bottom plate 1, and a movable cover 9 is provided on one end of the base 8. The movable cover 9 is opened It can be seen that the reaction barrel 10 is inside, the reaction barrel 10 is set inside the base 8, the water layer 11 is set inside the reaction barrel 10, a push plate 12 is set at the bottom of the water layer 11, and a smoke layer 13 is set below the push plate 12, An activated carbon layer 14 is provided below the gas layer 13. A water outlet pipe 7 is provided on the top of the water layer 11. A water inlet pipe 6 is installed on the top of the water outlet pipe 7. The water outlet pipe 7 is connected to the water layer 11 and the water inlet pipe 6 is connected to the cooling bucket 16.

Example 2

In addition, referring to Figs. 1-5, the difference from the first embodiment described above is that the water outlet pipe 7 is connected to the cooling bucket 16 through the water inlet pipe 6, and the water inlet pipe 6 is installed at the bottom end of the inclined bottom 18 of the slope. The water outlet pipe 7 enters the water inlet pipe 6 and finally enters the cooling bucket 16. The slope bottom 18 can make water return again. The drawer plate 5 is movably connected through the slide rail 17 and the protective cover 2, and the length between the drawer plate 5 and the protective cover 2 Equal, in order to make the drawer plate 5 easy to pull out the protective cover 2, and the length of the two is equal so that the gap between the drawer plate 5 and the protective cover 2 is small, the protective cover 2 is connected to the smoke layer 13 through the smoking pipe 4, and the push plate is pushed 12 and the flue gas layer 13 communicate with each other. In order to make a large amount of smoke enter the flue gas layer 13, the pressure of the reaction barrel 10 rises, so that the push plate 12 moves upward to squeeze water into the water pipe 7, and the bottom of the molding tank 15 A cooling bucket 16 is provided, and the top of the molding tank 15 and the gate 3 are symmetrically arranged. In order to enable the automobile door panel initially shaped in the molding tank 15 to be rapidly cooled, and the gate 3 can accurately insert the injection molding material into the molding tank 15 Between the movable cover 9 and the base 8 It is movably connected, and the reaction barrel 10 is installed on the side close to the movable cover 9. In order to make the movable cover 9 open the base 8 conveniently, the internal reaction barrel 10 is convenient for maintenance.

When the utility model is in use, first, the molten injection molding material is poured into the protective cover 2 along the gate 3 on the top of the protective cover 2, and the injection molding material enters the molding groove 15 for slow molding. A large amount of smoke is generated inside, and the inhalation of smoke into the body will affect health. The smoking pipe 4 sucks the smoke into the smoke layer 13 inside the reaction barrel 10, and the inside of the reaction barrel 10 is caused by a large amount of smoke in the smoke layer 13 The air pressure rises, and the rising air pressure pushes the push plate 12 to move upwards, squeezes the water in the water layer 11 into the water outlet pipe 7, and then enters the cooling bucket 16 along the water inlet pipe 6, and the cooling bucket 16 fits at the bottom of the molding tank 15, The injection molding material in the tank 15 is rapidly cooled. After a period of time, the activated carbon layer absorbs the flue gas, the internal pressure of the reaction barrel 10 is restored, and the bottom 18 of the slope returns the water to the water layer, so that the device can be repeatedly operated. Finally, the drawer plate 5 is pulled out It is sufficient to take out the automobile door panel in the molding groove 15.
