Detailed Description
The following description of the embodiments refers to the accompanying drawings, which are included to illustrate specific embodiments in which the invention may be practiced.
As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the present embodiment discloses a fixed die plate mold ejection device, which includes a fixed die plate 1 and at least one ejection cylinder 2, wherein the top of the fixed die plate 1 has at least one inward recessed mounting groove 11, the mounting grooves 11 are in one-to-one correspondence with the ejection cylinders 2, one end of the ejection cylinder 2 is installed in the mounting groove 11, and the other end of the ejection cylinder 2 can move telescopically and can extend out of the mounting groove 11 or retract into the mounting groove 11.
The ejection oil cylinder 2 is arranged in the fixed die plate 1, the die unloading work is realized through the pushing-out action of the ejection oil cylinder 2, the die unloading work can be rapidly completed in a short time, and therefore the rapid die unloading is realized. When the fixed template mold ejection device needs to work, the ejection oil cylinder 2 extends out of the mounting groove 11, so that the mold sprue bush and the injection chamber can be separated mechanically and automatically, and the fixed template mold ejection device is safe and reliable in the working process.
The number of the ejection oil cylinders 2 is two, and the two ejection oil cylinders 2 are respectively arranged at two ends of the fixed die plate 1. 2 mounting grooves 11 with the same size are processed in the fixed die plate 1, the two ejection oil cylinders 2 are respectively arranged on the 2 mounting grooves 11, the die is pushed out from the flange of the feeding barrel when the die is changed through the two ejection oil cylinders 2, the die unloading work can be rapidly completed in a short time, the rapid die unloading is realized, and the stability and the reliability are high.
The ejection oil cylinder 2 comprises a cylinder sleeve 21, an integral piston rod 22 and an oil cylinder front cover 23, the cylinder sleeve 21 is arranged in the installation groove 11, the oil cylinder front cover 23 is inserted into the installation groove 11 and connected to the fixed template 1, the integral piston rod 22 is installed in the cylinder sleeve 21 and penetrates through the oil cylinder front cover 23, the integral piston rod 22 can stretch and move in the cylinder sleeve 21, and the oil cylinder front cover 23 is used for limiting the integral piston rod 22 to be separated from the installation groove 11. The cylinder sleeve 21 is arranged in the installation groove 11, the integral piston rod 22 is installed in the cylinder sleeve 21, and finally the oil cylinder front cover 23 is connected with the fixed die plate 1 to realize the installation and locking. The rapid die unloading is realized by the telescopic movement of the integral piston rod 22; meanwhile, the ejection oil cylinder 2 is simple in structure, practical and convenient.
The oil cylinder front cover 23 is arranged in the mounting groove 11, and the end surface of the oil cylinder front cover 23 is not exposed out of the outer surface of the fixed die plate 1. The oil cylinder front cover 23 is not exposed out of the outer surface of the fixed die plate 1 and is positioned in the mounting groove 11, so that the large plane of the fixed die plate 1 can be tightly attached to the die surface of the die without a gap, and the fixed die plate die ejector cannot generate an interference phenomenon. When the fixed die plate mold ejection device is not used, the integral piston rod 22 retracts into the mounting groove 11, so that the whole structure of the fixed die plate mold ejection device cannot be exposed out of the outer surface of the fixed die plate 1.
