Detailed Description

The present invention will be further described with reference to the following detailed description of preferred embodiments thereof, which is to be read in connection with the accompanying drawings.

First, an automatic gate shearing jig according to an embodiment of the present invention will be described with reference to fig. 1~5, which is used for shearing a gate 4 in a mold, instead of a manual work.

As shown in 1~5, the utility model discloses an automatic shearing runner tool of embodiment has back template 1, back mould benevolence 2 and automatic shearing module.

Specifically, as shown in fig. 1 and 5, in the present embodiment, the rear mold core 2 is disposed on the rear mold plate 1; the automatic shearing module is arranged in the rear mold core 2 and the rear mold plate 1 and is used for automatically shearing the sprue 4. The back mould benevolence 2 is put in back template 1 support, and back mould benevolence 2 is used for moulding plastics of product 5, can realize through the automatically cropped module that the runner 4 behind the 5 injection moulding of automatically cropped product cuts the separation with product 5 and runner 4, reduces the manpower demand, reduces the shaping cycle, improves production efficiency.

Further, as shown in fig. 1~3, the auto-shearing module comprises: a shear assembly and a drive assembly. In the embodiment, the shearing assembly is arranged inside the back mold core 2; the driving assembly is arranged in the rear template 1 and drives the shearing assembly to shear the pouring gate 4, so that automatic shearing processing is realized.

Further, as shown in fig. 1~3, in the present embodiment, the shearing module includes: spring 32 seat 31, spring 32 and cutter 33. The spring 32 seat 31 is arranged inside the rear die core 2; the spring 32 is arranged in the spring 32 seat 31; the cutter 33 is arranged inside the rear die core 2 and the bottom end of the cutter 33 is connected with the spring 32 seat 31. The cutter 33 can be driven to move upwards by enabling the spring 32 seat 31 to move upwards, so that the sprue 4 is cut, and the spring 32 is used for driving the spring 32 seat 31 to reset, so that the cutter 33 resets.

Further, as shown in fig. 1~3, in the present embodiment, the shearing module further includes: and the guide insert 34 is arranged in the back mold core 2 and used for guiding the cutter 33 and ensuring the accuracy and stability of the cutting of the gate 4 by the cutter 33.

Further, as shown in 1~3, in the present embodiment, the cutting knife 33 is perpendicular to the spring 32 seat 31, so that the cutting knife 33 can cut the gate 4 upwards in a stable straight line under the driving of the spring 32 seat 31.

Further, as shown in fig. 1~3, in the present embodiment, the driving assembly includes: an ejector plate 35, a bottom plate 36, a high-pressure cylinder 37 and an ejector rod 38. The ejector plate 35 is arranged at the bottom of the rear template 1; the bottom plate 36 is arranged at the bottom of the ejector plate 35; the high-pressure oil cylinder 37 is arranged on the bottom plate 36; the ejector rod 38 is arranged inside the ejector pin and the rear template 1, the top end of the ejector rod 38 is attached to the spring 32 seat 31, and the bottom end of the ejector rod 38 is connected with the high-pressure oil cylinder 37. The ejector plate 35 and the bottom plate 36 are used for supporting and installing a high-pressure oil cylinder 37, and the high-pressure oil cylinder 37 is used for driving an ejector rod 38 to eject upwards and eject the spring 32 seat 31.

Further, the center point of the lower wall surface of the spring 32 seat 31 and the center point of the upper wall surface of the ejector rod 38 are on the same straight line, so that the ejector rod 38 can eject the center of the spring 32 seat 31, the spring 32 seat 31 moves upwards stably, the spring 32 seat 31 is prevented from being inclined and deviated easily during ejection, and the cutting effect of the cutter 33 is indirectly influenced.

The spring 32 can reset the spring 32 seat 31, so that the cutter 33 is indirectly driven to reset, the mold can perform normal mold opening action, and when the injection molding machine gun barrel punches the mold cavity to keep the pressure, the high-pressure oil cylinder 37 performs ejection action under the action of the oil pressure motor of the injection molding machine. The knock-out rod 38 is moved upward by the force of the high-pressure cylinder 37. The ejector rod 38 abuts against the spring 32 seat 31 to move the spring 32 seat 31 upward. The cutter 33 cuts the gate upwards under the upward acting force of the spring 32 seat 31, so that the product 5 is separated from the gate 4, and after the gate 4 is cut by the cutter 33, the mold is opened normally.

Above, have described with reference to 1~5 according to the utility model discloses an automatic cutout runner tool, at 2 internally mounted sprues 4 cutters 33 of back mould benevolence, will advance the separation of sprue 4 excision and product 5 when making the injection molding machine pressurize end, reduce the manpower demand, reduce the shaping cycle, simplify the mould structure, improve production stability, simplify the mould structure, reduce the mould maintenance cost.
