Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1 and 2, for the utility model discloses a gate cutter, including base 1, the shutdown mechanism of installing on base 1 and the drive assembly that drives shutdown mechanism and remove in vertical direction, in this embodiment, drive assembly is cylinder 9. A controller is arranged on the side edge of the air cylinder 9, and two switch buttons and an emergency stop button are arranged on the two sides of the base 1. The top surface of the base 1 is provided with a mounting plate 3 with a U-shaped section and a fixing jig 4 borne on the mounting plate 3, and the fixing jig 4 is designed and manufactured according to the drawing of a product and a thick sprue. The fixed jig 4 is parallel to the base 1, and a clamping groove 41 for clamping and embedding the product and the thick sprue is formed in the top surface of the fixed jig 4. All seted up guide way 31 on the relative two inside walls of mounting panel 3, guide way 31 sets up along mounting panel 3's width direction, and fixed tool 4 slides and sets up in guide way 31. The length, width and height of the fixed jig 4 are all larger than those of the product and the thick sprue.

Referring to fig. 2 and 5, in order to facilitate the pushing and pulling of the fixing jig 4, a handle 44 is fixed to one end surface of the fixing jig 4 by a screw. The back of the mounting plate 3 is connected with an inductive switch 5 for inducing the fixed jig 4 to move in place, a product and a thick sprue are placed in a clamping groove 41 in the fixed jig 4, the fixed jig is pushed to the position of the inductive switch 5 by a handle 44, and the driving component can descend. An inclined guide plate 32 is arranged on the inner bottom wall of the mounting plate 3, one end, far away from the inductive switch 5, of the inclined guide plate 32 is arranged obliquely downwards, after the thick sprue is cut off from a product, the product falls down from the clamping groove 41, and slides down along the inclined guide plate 32 under the action of gravity of the product. To facilitate the collection of the cut products, a collecting box 8 is placed on one side of the base 1 close to the inclined guide plate 32.

Referring to fig. 3 and 4, the cutting mechanism includes a fixed cover 2 coupled to a driving end of the cylinder 9 and four upper cutters 21 provided on a bottom surface of the fixed cover 2. In order to improve the accuracy in cutting, a positioning assembly for ensuring the tool setting accuracy is fixed on the bottom surface of the fixed cover plate 2. In this embodiment, the positioning assembly includes four positioning pillars 22 arranged on the bottom surface of the fixed cover plate 2 in a rectangular array, correspondingly, the top surface of the fixed fixture 4 is provided with four positioning holes 42 for the positioning pillars 22 to be inserted, and the rectangular array of the positioning holes 42 is distributed with four. The top surface of the base 1 is provided with two guide posts 6 vertical to the top surface of the base 1, and the fixed cover plate 2 is provided with a through hole 61 for the guide posts 6 to pass through. When the cylinder 9 drives the fixed cover plate 2 to descend, the fixed cover plate 2 descends along the guide post 6 all the time, and the fixed cover plate 2 is guaranteed not to shift in the vertical direction, so that the notch is guaranteed to be flat.

Referring to fig. 4 and 6, a lower cutter 43 corresponding to the upper cutter 21 is fixed in the slot 41, and an elastic plate 7 parallel to the fixed cover plate 2 is fixed on the positioning column 22 in order to prolong the service life of the upper cutter 21 and the lower cutter 43 and reduce the impact force during tool setting. An elastic member 71 having an elastic direction consistent with the axial direction of the positioning column 22 is disposed between the elastic plate 7 and the fixed cover plate 2, and in this embodiment, the elastic member 71 is a spring. The elastic member 71 is sleeved on the positioning column 22, and the elastic plate 7 is provided with a yielding hole 72 for the upper cutter 21 to pass through. After the fixed apron 2 of cylinder 9 drive descends, the springboard 7 offsets with fixed tool 4 at first for fixed tool 4 is difficult for removing, thereby guarantees the stability when cutter 21 cuts off the runner, improves the precision of cutting off, thereby reduces the product defective rate.

The implementation principle of the embodiment is as follows: the product and the thick gate are placed in the slot 41 of the fixture 4, and the fixture is pushed to the position of the inductive switch 5 by the handle 44, and the driving component is lowered. After the cylinder 9 drives the fixed cover plate 2 to descend, the elastic plate 7 firstly offsets with the fixed jig 4, so that the fixed jig 4 is not easy to move.

The fixed cover plate 2 continues to descend after compressing the elastic piece 71, the upper cutter 21 extends out of the abdicating hole 72 and is aligned with the lower cutter 43 on the fixed jig 4, so that the thick sprue of the product is automatically separated from the product, a plurality of sprues are cut off at one time, time and labor are saved, the working efficiency is improved, the notch is smooth, and the reject ratio of the product is reduced.

After the thick gate and the product are cut off, the product falls from the slot 41, and slides down along the inclined guide plate 32 under the action of the gravity of the product and falls into the collection box 8. The cylinder 9 drives the fixed cover plate 2 to move upwards, the elastic piece 71 returns, and the worker draws the fixed jig 4 outwards along the guide groove 31 to take out the thick sprue.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
