Abstract

The utility model discloses a gate cutting device, which comprises a substrate (1) and is characterized in that the substrate (1) is longitudinally provided with a guide pillar (2); the guide pillar (2) is fixedly connected with a falsework (3); a gear (4) and a rack (5) which are meshed are arranged in the falsework (3); both ends of the rack (5) are smooth surfaces and are glidingly sheathed in the falsework (3); a handle (6) arranged outside the falsework (3) is fixedly connected with the axes of the gear (4); the lower end of the rack (5) is provided with an upper cutter (7); a lower cutter (8) arranged on the substrate (1) is matched with the position of the upper cutter (7); and a stop block (9) connected with the upper end of the rack (5) is located above the falsework (3). The gate cutting device has simple structure, skillful design, low labor strength and high production efficiency, can cut a main runner, trim a shunt gate and prune burrs and can complete the suspension work at a time.

Description

Pouring-head cutting device

Technical field

The utility model relates to a kind of cast gate instrument of cutting, especially a kind of can noresidue burr and suspension, make otch neat, level and smooth, avoid in cutting the cast gate operation, producing defective products the pouring-head cutting device of enhancing productivity.

Background technology

In the production of injection molding product, the product after the moulding all needs in general to need to rely on the operator to use and water brank through the step of cutting cast gate, and the excision sprue is pruned burr that finishing touch is residual and suspension to the shunting cast gate more earlier; So not only operation is loaded down with trivial details, and the operator's that places one's entire reliance upon skills involved in the labour, is difficult to obtain standardization, unitized product; When cutting cast gate work, also may cause the breakage of product simultaneously because of operator's error.Therefore need a kind of can addressing the above problem, can reduce labour intensity, can realize that standardization cuts cast gate, the device of enhancing productivity now.

Summary of the invention

The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, propose a kind of simple in structure, the design ingenious, can once finish and cut off sprue, prune shunting cast gate and dressing burr, suspension work, labour intensity is low, the pouring-head cutting device that production efficiency is high.

Concrete solution of the present utility model is: a kind of pouring-head cutting device, comprise pedestal 1, it is characterized in that: on pedestal 1, be vertically arranged with guide pillar 2, be fixedly connected with falsework 3 on the guide pillar 2, be provided with pitch wheel 4 and tooth bar 5 in the falsework 3, the both ends of tooth bar 5 are shiny surface, slip cap is connected in the falsework 3, being arranged on falsework 3 outer handles 6 fixedlys connected with the axle center of gear 4, the lower end of tooth bar 5 is provided with fixes a cutting tool 7, the bottom tool 8 that is arranged on the pedestal 1 matches with 7 positions of fixing a cutting tool, and the limited block 9 that links to each other with tooth bar 5 upper ends is positioned at falsework 3 tops.

Described tooth bar 5 protrudes on the part of falsework 3 tops and is socketed with back-moving spring 10.

The upper end of described limited block 9 and tooth bar 5 is for being threaded.

The utility model is compared with prior art, has following advantage:

Utilize pouring-head cutting device described in the utility model once cutting off in the action, finish and cut off sprue in the manual operations in the past, prune the work of shunting cast gate and dressing burr, suspension, greatly saved operator's labour intensity, improved production efficiency, and the cast gate after cutting off is neat, level and smooth, can allow the cast gate of product realize standardization, unitized, reduce because of cutting the disqualification rate of product in the cast gate operation; And this device is simple in structure, makes simply, with low cost, so it possesses extensive market prospects, very helps applying in the art.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.As Fig. 1, Fig. 2, shown in Figure 3: a kind of pouring-head cutting device, comprise pedestal 1, on pedestal 1, be vertically arranged with guide pillar 2, be fixedly connected with falsework 3 on the guide pillar 2, according to actual needs, falsework 3 can change the fixed position on guide pillar 2; Falsework 3 inside are provided with pitch wheel 4 and tooth bar 5, the both ends up and down of tooth bar 5 are shiny surface, can do to move longitudinally in falsework 2, then fixedly connected with the handle 6 that is arranged on falsework 3 outsides in the axle center of tooth bar 4, promptly by pulling handle 6 tooth bar 4 rotated; Fix a cutting tool 7 being provided with bottom of tooth bar 5, and the bottom tool 8 that is fixed on the pedestal 1 matches with 7 the position of fixing a cutting tool, fix a cutting tool 7 with the bottom tool 8 small distance that staggers mutually in the horizontal, utilize the gate cutting of the strength of two cutter relative motions with product 11; On the tooth bar 5 that is positioned at above the falsework 3, be socketed with back-moving spring 10, the upper end of tooth bar 5 also is threaded with limited block 9.

The course of work of the pouring-head cutting device of the utility model embodiment is as follows: when need be with the gate cutting of product 11, at first with product 11 below that is placed on bottom tool 8 as shown in Figure 3, gate portions is placed on accordingly on the cutter head of bottom tool 8, downward then pulling handle 6, under the drive of handle 6, gear 4 begins to rotate, and drive tooth bar 5 moves downward, fix a cutting tool 7 with bottom tool 8 move toward one another, the cast gate place is cut off; In the process that tooth bar 5 moves downward, be positioned at the also movement therewith of limited block 9 of its upper end, when the bottom of limited block 9 contacted with falsework 3 tops, tooth bar 5 stopped to move, and 7 excessive movements prevent to fix a cutting tool; After cast gate is cut off, unclamp handle 6, under the effect of back-moving spring 10, tooth bar 5 moves upward, driven gear 4 counter-rotatings, and handle 6 returns back to initial position.

According to size, shape and the user's of the product of required cutting actual conditions, it is fixing after the relative altitude on the guide pillar 2 to adjust falsework 3; According to needed depth of cut, can adjust the spiral degree of depth of limited block 9, decide 7 extreme positions that move downward of fixing a cutting tool.
