Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 and fig. 2, in a preferred embodiment, the mold of the semi-automatic mold closing of the present invention mainly comprises an upper mold set 1 and a lower mold set 2, wherein the upper mold set 1 and the lower mold set 2 are made of metal, a cavity 3 is disposed on the upper surface of the lower mold set 2, an injection port 4 communicated with the cavity 3 is disposed on the side of the lower mold set 2, and a casting material can be injected into the cavity 3 through the injection port 4. The upper die set 1 comprises a base body 5, a vertical downwardly extending core pulling 6 is arranged on the lower surface of the base body 5 corresponding to the die cavity 3, and during die assembly, the end of the core pulling 6 extends into the die cavity 3 and is matched with the die cavity 3 to form the shape required by a casting.

The upper module 1 is provided with a core-pulling protection structure, and the core-pulling protection structure comprises a protection plate 7 and at least one elastic piece 8. The protection plate 7 is rectangular and is arranged below the base body 5 and opposite to the base body 5, the elastic piece 8 is arranged between the protection plate 7 and the base body 5, the protection plate 7 keeps a fixed distance from the base body 5 under the elastic action of the elastic piece 8, and when pressure is applied to the protection plate 7, the protection plate 7 can vertically move relative to the base body 5. The protection plate 7 is provided with an avoiding hole 9 corresponding to the loose core 6, and when the elastic piece 8 is in an initial state, the end part of the loose core 6 is accommodated in the avoiding hole 9, so that the loose core 6 is prevented from colliding with the outside. When the elastic piece 8 is compressed, the end part of the loose core 6 passes through the avoidance hole 9 from top to bottom and extends out of the lower end face of the protection plate 7.

The elastic member 8 includes a guiding post 10 and a spring 11, two ends of the guiding post 10 are respectively connected with the seat 5 and the protection plate 7, it should be noted that the guiding post 10 can be movably connected at two ends, or one end thereof is movably connected, so as to ensure that the protection plate 7 can move relative to the seat 5. The spring 11 is sleeved on the periphery of the guide post 10 and provides restoring elasticity for the protection plate 7.

At least one limiting column 12 is vertically arranged on the upper surface of the protection plate 7, and in the embodiment, the number of the limiting columns 12 is four, and the four limiting columns are respectively arranged at four corners of the upper surface of the protection plate 7. During the compound die, pedestal 5 moves and offsets with spacing post 12 behind the certain distance, and the moving distance of pedestal 5 is the length that 6 stretched out protection shield 7 lower extreme face promptly for loosing core this moment, that is to say, the length of 6 stretching into die cavity 3 of loosing core when can adjusting the compound die through the length of adjusting spacing post 12, makes the use of mould more nimble convenient.

The lower surface of protection shield 7 is equipped with a plurality of reference columns 13, and the upper surface of lower module 2 is equipped with the locating hole corresponding to reference column 13, before the compound die, inserts the reference column 13 of protection shield 7 in the locating hole to form the location to last module 1,

lower module

2 and 6 of loosing core, then carry out the compound die, can avoid 6 of loosing core to bump with the inner wall of die cavity 3 because of the location is inaccurate, thereby the protection is loosed core 6 and mould.
