DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a fast demoulding hot pressing forming mold for automobile interior decoration parts, comprising a lower mold 1, a top plate 101 connected to the lower mold 1, four guide pillars connected to the top of the lower mold 1, the top of the four guide pillars are commonly connected to the bottom of the top plate 101, a hydraulic rod is installed on the top of the top plate 101, an upper mold 2 slidably connected to the bottom of the top plate 101, the bottom end of the hydraulic rod is connected to the top of the upper mold 2, the upper mold 2 is slidably connected to the outer wall of the four guide pillars, and a mold groove 201 connected to the inside of the lower mold 1;

[0027] After the plastic part is placed in the mold cavity 201 and heated, the hydraulic rod is driven to drive the upper mold 2 to move downward, thereby squeezing the plastic part in the mold cavity 201 to form it.

[0028] Two pressing plates 3 are slidably connected to the top of the lower mold 1, and each pressing plate 3 has a slot adapted to the upper mold 2;

[0029] When the upper mold 2 moves up and out of the mold groove 201, the lower end of the upper mold 2 can move in the internal slot of the pressure plate 3. Under the action of the pressure plate 3, the interior decoration parts inside the mold groove 201 can be prevented from moving up synchronously with the upper mold 2, thereby effectively separating the interior decoration parts adhered to the outer wall of the upper mold 2 from the upper mold 2.

[0030] A driving mechanism is provided inside the lower mold 1 to push the two pressing plates 3 to move horizontally;

[0031] Through the driving mechanism, the two pressing plates 3 can be translated on the surface of the lower mold 1, so as to facilitate the subsequent separation of the interior decoration parts from the mold cavity 201;

[0032] A push plate 4 is slidably connected inside the mold groove 201. By driving the push plate 4 to rise and fall inside the mold groove 201, the interior decoration parts formed inside the mold groove 201 can be ejected, thereby facilitating rapid demoulding of the interior decoration parts.

[0033] The driving mechanism includes a connecting rod 1 301, a connecting rod 2 302, a rack 303, a gear 304 and a driving member;

[0034] Two connecting rods 301 are rotatably connected inside the lower mold 1, and the upper and lower ends of each connecting rod 1 301 are rotatably connected to connecting rods 302. The other end of any connecting rod 2 302 is rotatably connected to the inner wall of the pressure plate 3, and the other end of the other connecting rod 2 302 is rotatably connected to the rack 303. The outer walls of the two racks 303 are meshed with a gear 304, and the gear 304 is rotatably connected to the inner wall of the lower mold 1.

[0035] The driving member includes a motor and a rotating rod 305;

[0036] The outer wall of the lower mold 1 is connected with a motor, and a rotating rod 305 is sleeved on the output end of the motor. The rotating rod 305 is rotatably connected to the inner wall of the lower mold 1, and the gear 304 is sleeved on the outer wall of the rotating rod 305.

[0037] By driving the motor, the rotating rod 305 rotates, which in turn drives the gear 304 to rotate synchronously, so that the two racks 303 meshing with the outer wall of the gear 304 move horizontally inside the lower mold 1, and the connecting rod 2 302 connected to the rack 303 moves synchronously, thereby driving the connecting rod 1 301 to rotate inside the lower mold 1, and the connecting rod 2 302 connected to the top of the connecting rod 1 301 pulls the pressure plate 3 to slide on the surface of the lower mold 1, so that the two pressure plates 3 no longer block the mold groove 201.

[0038] Four T-shaped slide grooves are provided inside the lower mold 1 , and a T-shaped slider is slidably connected inside each set of T-shaped slide grooves, and every two T-shaped sliders are connected to the bottom end of any pressing plate 3 .

[0039] The pressing plate 3 moves on the surface of the lower mold 1 and drives the T-shaped slider to slide inside the T-shaped slide groove, thereby limiting the pressing plate 3 when it moves.

[0040] Two movable plates 404 are connected to the bottom end of the push plate 4 , and each movable plate 404 is slidably connected to the inside of the mold cavity 201 .

[0041] The outer wall of the rotating rod 305 is connected with two conical teeth 1 401 , and the outer wall of each conical tooth 1 401 is meshed with a conical tooth 2 402 . The interior of each conical tooth 2 402 is connected with a screw rod 403 , and each screw rod 403 is threadedly sleeved inside the movable plate 404 .

[0042] The rotating rod 305 drives the gear 304 to rotate, and at the same time drives the conical tooth 1 401 to rotate, so that the conical tooth 2 402 meshing with the outer wall of the conical tooth 1 401 rotates synchronously, and the screw 403 rotates inside the lower mold 1, so that the movable plate 404 slides inside the lower mold 1 and drives the push plate 4 to slide inside the mold groove 201, so that the push plate 4 can push the formed interior decoration parts out of the mold groove 201.

[0043] Two limit blocks are connected to the bottom end of the outer wall of each movable plate 404. When the movable plate 404 moves, it drives the limit blocks to move synchronously, which can prevent the movable plate 404 from escaping from the mold cavity 201, thereby limiting the moving distance of the movable plate 404.

[0044] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
