Embodiment
[0049] Example: figure 2 A transmission controller bracket molding die disclosed by the present invention includes a movable template 4 and a fixed template 5 , the fixed template 5 is fixed in position, and the movable template 4 can move relative to the fixed template 5 . A gate 6 and a movable core 7 are fixed inside the movable template 4 (see image 3 ), the fixed template 5 is fixed with a fixed core 8 (see Figure 4 ).
[0050] like figure 1 As shown, a plate-shaped blocking piece 2 and a T-shaped blocking piece 2 are integrally formed vertically on the bottom plate 1 of the gearbox controller bracket, wherein the flat-shaped blocking pieces 2 are all located on one side of the bottom plate 1, and the T-shaped blocking piece 2 The two ends of the blocking piece 2 are located on both sides of the bottom plate 1 respectively.
[0051] like image 3 As shown, the surface of the fixed template 5 facing the movable template 4 is provided with two slide grooves, and a s...

The invention relates to the technical field of pressure casting, in particular to a gearbox controller support mold and a forming method thereof. The mold comprises a movable mold plate and a fixed mold plate. A sprue and a movable mold core are arranged in the movable mold plate, a fixed mold core is arranged in the fixed mold plate, an air cylinder is fixed to the side face of the fixed mold plate, a sliding block is connected to a piston rod of the air cylinder, a mold cavity is defined by the sliding block, the movable mold core and the fixed mold core, and the large side face of a blocking piece formed in the mold cavity is flatly attached to the sliding block, an oil cylinder with the fixed position is included, the fixed mold plate is located between the oil cylinder and the movable mold plate, a piston rod of the oil cylinder is connected with a first ejecting rod, a casing pipe is fixed in the fixed mold core, the top of the first ejecting rod is connected with an ejector pin, and the first ejecting rod, the ejector pin, the casing pipe and a column foot formed in the mold cavity are coaxial. Through the method that through ejector pin core pulling, a round groove is formed, a thread rod is machined, and the sliding block is controlled to release the inner stress of the bottom plate multiple times, the effect that the formed product does not deform is achieved.
Description
technical field [0001] The invention relates to the technical field of die casting, in particular to a mold for forming a gearbox controller bracket and a forming method thereof. Background technique [0002] At present, because the manual transmission vehicle has higher requirements on the driver and the operation is complicated, the automatic transmission vehicle is more and more popular. [0003] For automatic transmission vehicles, the front-end electronic shifter issues shift commands, and the electronic shift actuator performs mechanical actions to drive the gearbox to change gears, and feeds back the electrical signal of the gear position at that time to realize the gear shifting function. The electronic gear shift actuators in the prior art are generally relatively large in size, resulting in inconvenient installation in the limited space inside the car and occupying space. In order to reduce the space occupied by the electronic gear shift actuator, one method is to...
