The transfer type ejector pin demoulding device is composed of a plurality of independent ejector pin mechanisms, each independent ejector pin mechanism comprises an independent ejection cylinder and a corresponding ejector pin, and the ejector pins can stretch into a die cavity along ejector pin holes formed in the die under the driving of the ejection cylinders to finish ejection actions. The mold working condition monitoring device comprises a temperature sensor and a pressure sensor which are arranged in a mold cavity.
The independent thimble mechanisms are divided into two types, one type is a main thimble mechanism 1, the other type is an auxiliary thimble mechanism 2, the number of the main thimble mechanisms 1 is 3, the main thimble mechanisms are uniformly distributed along the central line position when the automobile power battery box is formed, the position corresponds to the position with the highest wall thickness strength of a product, larger thrust can be borne, the middle position helps to uniformly diffuse local stress to the periphery, the local pressure is further reduced, the number of the auxiliary thimble mechanisms 2 is 4, the auxiliary thimble mechanisms are symmetrical in pairs, and the auxiliary thimble mechanisms are distributed along the corresponding positions of the flange edge when the automobile power battery box is formed. The ejector pins are arranged in the mode, so that the situation that when the ejector pins are ejected, the surface of the power battery box of the automobile is damaged due to overlarge local stress on the surface of the power battery box can be prevented, and the main ejector pin mechanism and the auxiliary ejector pin mechanism are symmetrically distributed, so that the ejection adjustment can be correspondingly performed according to the symmetry principle when the local die sticking occurs.
The temperature sensor 3 and the pressure sensor 4 are arranged at the bottom of the die cavity of the fixed die and are externally connected with a human-computer interaction interface through data lines. The reason for this is to reduce the direct effect of the gate feed on the real time data from the temperature and pressure sensors. The temperature sensor 3 is arranged at the middle position of the bottom of the fixed die cavity, and the middle position has higher indication significance on the temperature of the fluid in a stable state. Wherein pressure sensor 4 total 3 lay respectively in cover half die cavity central point, marginal position and the position that has complex structure and be close to die cavity intermediate position, can effectively reflect the pressure gradient of fluid in different positions in the forming process, and then confirm whether marginal position and complex structure position accomplish the action of filling the mould, can prevent that the shaping defect from appearing in the product.
