Detailed Description

To facilitate understanding of those skilled in the art, the present invention will be described in further detail below with reference to specific embodiments and the accompanying drawings.

Referring to fig. 1-5, a preferred embodiment of the present invention is shown.

Referring to fig. 1 and 2, a mold structure capable of preventing sundries from flying in comprises a movable mold (1) and a fixed mold (2), wherein an air outlet block (3) is arranged on the periphery of the movable mold (1), a wind blocking block (4) is arranged on the periphery of the fixed mold (2), and the air outlet block (3) and the wind blocking block (4) are arranged oppositely; the upper surface of the air outlet block (3) is provided with an annular air groove (32), the lower surface of the air outlet block (3) is provided with a plurality of air holes (31), the annular air groove (32) is communicated with the air holes (31), and the air holes (31) are all connected with an air inlet device (5).

This embodiment sets up out wind piece (3) and wind-break piece (4) respectively on movable mould (1) and location, and go out wind piece (3) and wind-break piece (4) and set up relatively, air inlet unit (5) convey gas to wind hole (31) and annular wind groove (32), make gas blow off from annular wind groove (32), and blow to wind-break piece (4), form one air curtain between play wind piece (3) and wind-break piece (4) promptly, the mould is when the die sinking, can effectively block impurity from the external world in flying into the mould through the effect of air curtain, thereby guaranteed the mould at the die sinking and the clean and tidy nature of reclosing the mould in-process, and clear away partial impurity, the forming quality of follow-up mould has been guaranteed.

Referring to fig. 1, in the present embodiment, the air inlet device (5) includes a fixing sleeve (51), an air pipe (52) and a blower (not shown), the fixing sleeve (51) is fixed at the air hole (31) and is communicated with the air hole (31), one end of the air pipe (52) is connected with the fixing sleeve (51), and the other end is connected with the blower. The fixed sleeve (51) is in threaded connection with the air outlet block (3). The air holes (31), the fixing sleeve (51) and the air pipe (52) are communicated with each other, and air produced by the blower sequentially passes through the air pipe (52), the fixing sleeve (51) and the air holes (31) and is finally blown out from the annular air groove (32). It should be noted that each air hole (31) corresponds to one air inlet device (5), and in order to save cost, a blower can be used for ventilating a plurality of air holes (31).

Referring to fig. 3, the air hole (31) of the present embodiment is a gradual changing hole, i.e. a circular truncated cone structure, and the diameter of the air hole (31) gradually decreases from the lower surface to the upper surface of the air outlet block (3) until the air hole is communicated with the annular air groove (32). The advantage of this kind of setting lies in, and wind blows to little aperture from big aperture, can effectively compress the volume for the wind pressure that blows out is bigger, and the wind channel is thinner.

Referring to fig. 4 and 5, in the present embodiment, the lower surface of the wind blocking block (4) is provided with a wind blocking groove (41), the wind blocking groove (41) is opposite to the annular wind groove (32), and the wind blocking groove (41) is an annular structure corresponding to the annular wind groove (32). The wind blocking groove (41) is of a gradual change structure, and the opening width of the wind blocking groove (41) is gradually reduced from the lower surface to the upper surface of the wind blocking block (4), namely, the wind blocking groove is of a trapezoidal structure. The wind blocking groove (41) can play a certain wind gathering role, and wind blown out from the annular wind groove (32) is prevented from contacting the wind blocking block (4) and then flying around.
