Further, the air outlet is a circular through hole.
Furthermore, the cross section of the clamping groove is V-shaped, and the shape of the lower end of the convex cylinder corresponds to that of the clamping groove.
Further, the bottom surface of the upper die is provided with an injection port.
The plastic cover body mold with the buffer mechanism is simple in structure and low in cost, a workpiece is easily separated from the lower mold when the workpiece is demolded, a worker can conveniently take the workpiece, and production efficiency is improved.
For a better understanding and practice, the invention is described in detail below with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic of the present invention.
Detailed Description
Referring to fig. 1, the present invention discloses a plastic cover mold with a buffer mechanism, which comprises an upper mold 10, a lower mold 20 and a demolding mechanism; a convex cylinder 11 protruding downwards is arranged at the bottom of the upper die 10, a clamping groove 21 is arranged on the surface of the lower die 20, and the convex cylinder 11 can be clamped into the clamping groove 21; after the upper die 10 and the lower die 20 are pressed together, a cavity for molding a plastic cover body is formed between the convex cylinder 11 and the lower die 20; the demolding mechanism comprises an air outlet hole 31, a demolding cylinder 32, a demolding module 33, an air guide pipeline 34 and a high-pressure air source 35; the air outlet hole 31 penetrates through the lower die 20 along the vertical direction, the demoulding block 33 is clamped into the air outlet hole 31, the upper end of a piston rod of the demoulding cylinder 32 is connected with the bottom surface of the demoulding block 33, and the demoulding cylinder 32 can drive the demoulding block 33 to move in the air outlet hole 31; the air guide duct 34 is arranged in the lower die 20, one end of the air guide duct 34 is connected with the high-pressure air source 35, the other end of the air guide duct is communicated to the air outlet hole 31, and the air guide duct 34 is communicated to the air outlet hole 31 from the side wall of the air outlet hole 31; the die further comprises a buffer mechanism, the buffer mechanism comprises a convex column 41, a containing groove 42 and a spring 43, the convex column 41 is arranged on the bottom surface of the upper die and positioned on the outer side of the convex column, the containing groove 42 is arranged on the top surface of the lower die, the containing groove 42 is positioned under the convex column 41, and the spring 43 is arranged in the containing groove 42. Before the upper die moves downwards to a position close to a target position, the convex column 41 is pressed against the spring 43, the downward movement speed of the upper die is slowed down by utilizing the elastic force generated when the spring 43 is compressed, and the phenomenon that the upper die moves too fast to cause large impact on the lower die is avoided.
The air outlet 31 is a circular through hole. The cross section of the clamping groove 21 is V-shaped, and the shape of the lower end of the convex cylinder 11 corresponds to that of the clamping groove 21. The bottom surface of the upper die 10 is provided with an injection port 12.
During the use, go up mould 10 to lower mould 20 pressfitting, the lower extreme card of protruding section of thick bamboo 11 is gone into to the draw-in groove 21, then liquid plastics follow in sprue 12 is to the die cavity, and after the work piece shaping, go up mould 10 and promote, drawing of patterns cylinder 32 drives it moves down to take off module 33, until will gas conduit 34 is in the export in venthole 31 exposes, then high-pressure gas source 35 to gas conduit 34 carries high-pressure gas, high-pressure gas passes through gas conduit 34 then follows venthole 31 flows out, from bottom to top with the work piece ejecting lower mould 20 makes things convenient for the workman to take off.
The plastic cover body mold with the buffer mechanism is simple in structure and low in cost, a workpiece is easily separated from the lower mold when the workpiece is demolded, a worker can conveniently take the workpiece, and production efficiency is improved.
The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
