Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment:

a high-efficiency mold cavity cleaning mechanism for injection molding comprises a first support frame 1, a first cavity 2 is arranged at the bottom end of the first support frame 1, a second support frame 3 is inserted into the first cavity 2, a chute 4 is arranged in the first support frame 1 at the left side in the first cavity 2, the sliding chute 4 is communicated with the first cavity 2, the sliding block 5 is arranged in the sliding chute 4 in a sliding way, the right side of the sliding block 5 is fixedly connected with the left side of the second supporting frame 3, when the second supporting frame 3 moves downwards in the first cavity 2, the second supporting frame 3 drives the sliding block 5 to slide downwards in the sliding groove 4, therefore, when the sliding block 5 slides downwards to a certain position, the sliding block 5 is blocked and limited by the inner wall of the bottom end of the sliding groove 4, at this time, the second supporting frame 3 is also limited, thereby avoiding the second support frame 3 and the first support frame 1 from falling off, and further influencing the use condition.

The right side of the second supporting frame 3 is evenly provided with a plurality of slots 6, a first through groove 7 is arranged in the first supporting frame 1 on the right side of the inner wall of the first cavity 2, a compression spring 8 is fixedly arranged in the first through groove 7, an inserting rod 9 is fixedly arranged at the left end of the compression spring 8, the inserting rod 9 is matched with the slots 6, a connecting groove 10 is arranged at the right side of the first supporting frame 1, the connecting groove 10 is communicated with the first through groove 7, a connecting rod 11 is inserted in the connecting groove 10, the left end of the connecting rod 11 is fixedly connected with the right end of the inserting rod 9, when the device is used, the left end of the inserting rod 9 is inserted in the slots 6, so that the second supporting frame 3 is fixedly connected with the first supporting frame 1, when the position of the second supporting frame 3 in the first cavity 2 needs to be adjusted, the connecting rod 11 is held to be pulled outwards, at the moment, the connecting rod 11 is forced to, at this moment, the inserting rod 9 is not clamped and matched with the inserting groove 6 any more, and the first supporting frame 1 can be held to be pulled up and down, so that the position of the second supporting frame 3 in the first cavity 2 is adjusted, the operation is simple and convenient, and the device is convenient for workers to operate and use.

The bottom end of the second supporting frame 3 is fixedly provided with a fixed bin 12, the fixed bin 12 is fixedly provided with a switch 22, the bottom end of the fixed bin 12 is provided with a second cavity 13, the top end inside the second cavity 13 is fixedly provided with a motor 14, all electrical appliances used in the application are products which can be directly purchased in the market, the principle of the electrical appliances is the prior art which is well known to the technical personnel in the field, the description is omitted, the bottom end of the motor 14 is fixedly provided with a rotating shaft 15, the bottom end of the rotating shaft 15 is provided with a connecting frame 17, the bottom end of the connecting frame 17 is fixedly provided with a sponge cleaning plate 16, the top end of the connecting frame 17 is provided with a second through groove 18, the bottom end of the rotating shaft 15 is inserted into the second through groove 18, the two sides of the rotating shaft 15 are both provided with second threaded grooves 20, the two sides of the connecting frame 17 are both provided with first threaded grooves, the inner part of the first thread groove 19 is provided with a bolt 21 through threads, the inserting end of the bolt 21 extends to the inner part of the second thread groove 20, the bolt 21 is held and rotated, when the bolt 21 rotates to a certain position, the bolt 21 is not connected with the second thread groove 20 for limiting, the connecting frame 17 is not connected with the rotating shaft 15, and the sponge cleaning plate 16 can be detached from the rotating shaft 15, so that the sponge cleaning plate 16 can be cleaned and replaced.

The working principle is as follows: when the staff uses this device, at first with this device switch on to for this device provides electric power and supports, through holding first support frame 1 during the use, aim at the die cavity that needs the clearance with sponge cleaning plate 16, open switch 22, starter motor 14, at this moment motor 14 work output drives axis of rotation 15 and rotates, thereby it is rotatory to drive sponge cleaning plate 16, through sponge cleaning plate 16 high-speed rotatory and with the die cavity laminating, thereby carry out high-efficient cleanness with the raw materials in the die cavity.

When the sponge cleaning plate 16 is contaminated with more raw materials and needs to be cleaned or replaced, the bolts 21 are screwed, and when the bolts 21 are screwed to a certain degree, the bolts 21 are no longer fixedly connected with the second thread grooves 20, and at this time, the connecting frame 17 is no longer fixedly connected with the rotating shaft 15, so that the sponge cleaning plate 16 can be detached, and the sponge cleaning plate 16 can be cleaned and replaced.

When the dark clearance of the degree of depth of some die cavitys is inconvenient, through holding connecting rod 11 and outwards stimulate, at this moment connecting rod 11 drives inserted bar 9 extrusion compression spring 8 and inwards shrink, when inserted bar 9 contracts to a certain position, inserted bar 9 no longer with slot 6 block cooperation, hold first support frame 1 at this moment and upwards stimulate, thereby adjustable second support frame 3 is in the inside position of first cavity 2, and then the height of adjusting device body, thereby the die cavity clearance of the more degree of depth of adaptation.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
