Detailed Description

The utility model provides a charging barrel dismounting jig, and in order to make the purpose, technical scheme and effect of the utility model clearer and clearer, the utility model is further described in detail below by referring to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit the scope of the utility model.

Referring to fig. 1-3, the utility model provides a charging barrel dismounting jig, which comprises a stop block 1 for placing into a charging barrel pouring port 41, wherein a portable structure is arranged at the top of the stop block 1, a first groove 11 is formed in the front end surface of the stop block 1, and a material pushing end of an injection plunger 2 can be opposite to the bottom surface facing the first groove 11 to realize impact.

When the charging barrel is disassembled, the injection head 2 firstly exits from the inner hole of the charging barrel, a worker lifts the check block 1 through a portable structure and puts the check block 1 into the pouring gate 41 of the charging barrel 4, the front end face of the check block 1 faces the injection head 2, and the check block 1 cannot axially move relative to the charging barrel 4 due to the limitation of the barrel wall of the charging barrel; then start the injection head 2, the injection head 2 stretches into the hole of feed cylinder 4, because dog 1 forms to block the injection head 2, the material pushing end of injection head 2 is pressed on the bottom surface of first recess 11, and the rear end face of dog 1 supports and presses on the section of thick bamboo wall of feed cylinder 4, then injection head 2 continues to promote dog 1 and feed cylinder axial displacement together, makes the feed cylinder break away from die casting machine 3 smoothly. The charging barrel dismounting jig provided by the utility model blocks the movement path of the injection head 2, and pushes the charging barrel 4 out of the die casting machine 3 skillfully by means of the driving force of the injection head 2, so that the dismounting efficiency is improved, and the labor force is saved.

In practical application, the block 1 is formed by machining cold-work die steel through a machine tool, and in order to avoid rigid collision between the pushing end of the injection plunger 2 and the block 1 to damage the injection plunger 2, a rubber layer is adhered to the bottom surface of the first groove 11 of the block 1.

Specifically, the top of dog 1 sets up for the arc top, is suitable for the structure of a batching section of thick bamboo on the one hand better, and on the other hand does not take place to interfere with die casting machine 3.

In this embodiment the handle structure comprises a hand grip 12 provided on an arc top 15 of the block 1. The stop 1 is lifted by the operator by holding the mouth 12.

In order to facilitate the extraction of the block 1, the hand holding openings 12 are symmetrically arranged, and the two hands of the worker can respectively hold the block 1 through the hand holding openings 12 to exert force.

Preferably, a threaded hole 13 is formed in the center of the arc top 15 of the stop block 1, the threaded hole 13 is matched with a hanging ring, and the hanging ring comprises a circular ring part and a screw part fixedly arranged at the bottom of the circular ring part. When the block 1 is difficult to take out of the pouring gate, the screw part is screwed into the threaded hole 13, the sling is penetrated in the circular ring part, and the sling is lifted by the suspension arm to enable the block 1 to move upwards to be separated from the pouring gate 41.

Preferably, in vertical projection, the bottom of the block 1 is V-shaped, i.e. forms a pointed corner 14 facing downwards. Through setting up like this, dog 1 puts into the sprue, and the closed angle 14 of dog 1 bottom supports presses on the inner wall of feed cylinder 4, ensures that the bottom of dog 1 can not cause the interference with the inner wall of feed cylinder 4.

Specifically, a second groove is formed in the rear end face of the stop block 1, and the first groove 11 and the second groove are identical in structure and are coaxially arranged. With this arrangement, even if the rear end face of the block 1 faces the injection plunger 2 when the block 1 is mounted, the dismounting work can be performed as usual, and the versatility is improved.

Preferably, the first groove 11 and the second groove are blind holes, which facilitate metal cutting on the one hand and also adapt to the shape of the press head 2 on the other hand.

Preferably, the radius of the arc top of the block 1 is the same as that of the barrel. During the sprue was put into to dog 1, dog 1 can inlay a complete axle form with the feed cylinder mutually for when the feed cylinder withdrawed from die casting machine 3, dog 1 can not take place to interfere with the mounting hole of die casting machine 3.

Preferably, the end faces of the two sides of the stop block 1 are vertically arranged, so that the stop block 1 is of a columnar structure.

In order to avoid the edge of the block 1 to be too sharp, the edge of the block 1 is chamfered.

It should be understood that the technical solutions and the inventive concepts according to the present invention may be equally replaced or changed by those skilled in the art, and all such changes or substitutions should fall within the protection scope of the present invention.
