Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automobile bumper injection mold. Background Art

[0002] The car bumper is a safety device that absorbs and mitigates external impact and protects the front and rear parts of the car body. In addition to maintaining the protective function, the front and rear bumpers of the car must also pursue harmony and unity with the body shape and pursue their own lightweight. The front and rear bumpers of the car are made through injection molding, which people call plastic bumpers.

[0003] The application number is CN202122003486.2, which discloses an automobile bumper injection mold, including a bottom plate: a top plate is provided above the bottom plate, the upper surface of the bottom plate is fixedly inlaid with a first bearing and a second bearing, and the bottom surface of the top plate is fixedly inlaid with a first bearing and a second bearing. The automobile bumper injection mold, through the motor provided, can allow the conveyor belt to indirectly drive the first threaded rod and the second threaded rod to rotate, and can realize the function of allowing the fixed plate to drive the upper mold to rise and fall. Through the cooperation of the pressure sensor provided and the single-chip microcomputer, the pressure sensor can transmit the signal to the single-chip microcomputer in real time, and the single-chip microcomputer can stop the servo motor from working, and can accurately control the thickness of the cast bumper, which is conducive to the later installation and use.

[0004] After the injection molding of the device is completed, during the process of removing the bumper, the connecting rod, the upper mold and the second threaded rod will block the bumper, which is easy to cause a collision during the process of removing the bumper, resulting in damage to the bumper. Utility Model Content

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is an injection mold for automobile bumper, comprising an operation box, a control button is fixedly connected to the front of the operation box, a top outlet is opened on the top of the operation box, and a moving mechanism comprises two slide rails fixedly connected to the top of the operation box, sliders are slidably connected inside the two slide rails, and a placement frame is fixedly connected to one end of the two sliders close to each other, so that the sliders can be conveniently moved, and the sliders can drive the placement frame to move.

[0007] Furthermore, a push rod is fixedly connected to one side of the placement frame away from the top outlet, and a connecting rod is rotatably connected to one end of the push rod away from the placement frame, and a rotator is fixedly connected to one end of the connecting rod away from the push rod. This arrangement is to enable the gears to mesh with each other so that they can rotate when they rotate around the threaded rod, thereby enhancing the cleaning effect.

[0008] Furthermore, a lifting mechanism is arranged above the placement frame, and the lifting mechanism includes a top plate slidably connected to the inner wall of the placement frame, and a plurality of springs are fixedly connected to the top of the top plate. This arrangement is to compress the springs when the top plate is pushed up by an external force, and the baffle can be quickly reset when the force pushing the baffle disappears.

[0009] Furthermore, a plurality of piston rods are fixedly connected to one side of the top plate close to the spring, a lower mold is fixedly connected to the top of the placement frame, and a plurality of piston holes are opened on one side of the lower mold close to the placement frame. This arrangement allows the safety rod to be ejected by moving the piston rod.

[0010] Furthermore, the interior of the piston hole is slidably connected to the outer wall of the piston rod, and a first electric telescopic rod is fixedly connected to the inner bottom of the operating box. The first electric telescopic rod is located directly below the control button. This arrangement is to facilitate the first electric telescopic rod to be raised above the operating box.

[0011] Furthermore, the diameter of the top plate is larger than the diameter of the bottom opening of the placement frame, and the springs are symmetrically arranged around the center of the top plate, so as to prevent the top plate from detaching from the bottom of the placement frame.

[0012] Furthermore, a casting mold mechanism is arranged above the operation box, and the casting mold mechanism includes a plurality of fixing rods fixedly connected to the top of the operation box, and one end of the fixing rods away from the operation box is fixedly connected to a mounting plate.

[0013] Furthermore, a second electric telescopic rod is fixedly connected to one side of the mounting plate close to the fixed rod, an upper mold is fixedly connected to an output end of the second electric telescopic rod, an injection pipe is connected to one side of the upper mold close to the second electric telescopic rod, and the right side of the upper mold is fixedly connected to an end of the rotator away from the connecting rod. This arrangement is used to drive the upper mold to move by the second electric telescopic rod to facilitate mold casting.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model controls the second electric telescopic rod to rise by a control button. When the second electric telescopic rod rises, the second electric telescopic rod drives the upper mold to rise. The rise of the upper mold drives the rotator to rise. The rise of the rotator drives the connecting rod to rise, so that the vertical length of the connecting rod changes. Therefore, the bottom end of the connecting rod moves to the left, thereby pushing the push rod to move to the left. The push rod pushes the placement frame to move to the left along the direction of the slide rail, thereby pushing the lower mold to the left, preventing the lower mold from colliding with the fixed rod and the upper mold when taking the bumper, causing damage to the bumper.

[0016] (2) The utility model starts the first electric telescopic rod, and the output end of the first electric telescopic rod rises, passes through the top outlet and contacts the top plate, and then pushes the top plate to rise. The rising top plate compresses the spring and pushes the piston rod to rise. The rising piston rod passes through the piston hole, so that the bumper is separated from the lower mold, which is convenient for removing the bumper.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
