The invention discloses an automobile shock absorber support forming die comprising a discharge device, a heating furnace, a die component, a feedback unit and a controller; one end of the heating furnace communicates with the discharge device through a feed pipe, and the other end communicates with the die component through a discharge pipe; the discharge pipe is provided with a first temperature detector, a discharge valve, a regulating valve and a second temperature detector, and the first temperature detector and the second temperature detector are arranged at both ends of the discharge pipe respectively; when the difference between a first detection temperature and a second detection temperature is larger than the preset threshold, a reflux signal is transmitted to the discharge valve from the controller, so that materials output from the heating furnace enter the feedback unit, or else enter the die component; the die cavity of the die component is provide with a capacity detector; when the capacity detector detects that the capacity of the materials in the die cavity of the die component reaches a first capacity threshold, the regulating valve is controlled by the controller to reduce the material flow rate of the discharge pipe; when the capacity of the materials reaches a second capacity threshold, the regulating valve is controlled by the controller and closed.
