Description

Technical Field

[0001] The utility model belongs to the technical field of production equipment for track fittings, and relates to an injection production line for track fittings. Background Art

[0002] Track fittings (embedded sleeves, under-rail pads, fasteners, etc.) are generally nylon parts produced by injection molding. During the injection molding process, the plastic is first heated to a temperature below the softening point by high temperature, and then the softened plastic is injected into the mold cavity under high pressure. After rapid cooling, the mold is opened to take out the product. Therefore, the internal stress concentration of the plastic product itself is the key to affecting the service life and strength of the plastic product. Usually, the products obtained by injection molding need to be subjected to water absorption modulation treatment. However, because the track fittings are all small parts, it is rather troublesome to carry out water absorption pre-treatment, and manual handling is mostly used, which is very troublesome. Therefore, in order to improve the production efficiency of track fittings, it is necessary to develop an automated production line for track fitting injection molding.

[0003] Chinese Utility Model Patent CN106629049U (Publication Date: May 10, 2017) discloses a water absorption conditioning treatment production line for nylon parts of high-speed and heavy-haul railway fasteners, including an injection molding machine, a conveying track, a water tank, and a motor. The conveying track is provided with conveying rollers, and the conveying rollers are driven by the motor. It is characterized in that: the conveying track includes a main track, an auxiliary track, a conditioning track, and a blanking track. The injection molding machines are distributed on both sides of the main track. The conditioning track is arranged at the bottom of the water tank. The feeding end of the conditioning track is connected to the main track through the auxiliary track, and the discharging end is connected to the blanking track through the auxiliary track.

[0004] Although the above production line realizes the automated production of track fittings, the materials entering the conveying track from the injection molding machine are in a disordered state. Their different positions, orientations, and stacking states will all affect their conveying speed, and the passing time when the materials pass through the water tank is also different, thus affecting the water absorption effect. Therefore, the injection production line for track fittings still needs further improvement. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an injection production line for track fittings, which realizes the automated production of track fittings and has the advantages of high production efficiency, good product quality, and reasonable and compact layout.

[0031] A second conveyor track 4, which conveys materials longitudinally. The conveying ends of the first conveyor tracks 2 are all connected to the second conveyor track 4, and the conveying end of the second conveyor track 4 corresponds to the sorting area 5 for packing materials into boxes;

[0032] A third conveyor track 6, which conveys the boxes longitudinally and is arranged above and below the second conveyor track 4. The conveying starting end of the third conveyor track 6 corresponds to the sorting area 5;

[0033] A fourth conveyor track 7, which conveys the boxes longitudinally and is arranged left and right of the third conveyor track 6. The conveying starting end of the fourth conveyor track 7 is connected to the conveying end of the third conveyor track 6. The conveying path of the fourth conveyor track 7 passes through a water tank 8, and its conveying end corresponds to a blanking area 9.

[0034] The operation process of this embodiment is as follows: The materials produced by the injection molding machine 1 fall from its discharge port 3 onto the first conveyor track 2. Each first conveyor track 2 conveys the materials produced by its corresponding injection molding machine 1 to the second conveyor track 4. The second conveyor track 4 conveys the materials uniformly to the sorting area 5. There are boxes placed in the sorting area 5, and the materials on the second conveyor track 4 automatically fall into the boxes. When the boxes are full, they are placed on the third conveyor track 6. The third conveyor track 6 conveys the boxes in the reverse direction to the fourth conveyor track 7. The fourth conveyor track 7 conveys the boxes into the water tank 8 for soaking and water absorption, and after leaving the water tank 8, they enter the blanking area 9 to complete the production.

The discharge port 3 of the injection molding machine 1 is provided with a discharge slide rail connecting the first conveying track 2, and the discharge slide rail is arranged to slope downwards along the conveying direction.

[0037] Since the third conveying track 6 has different conveying environments inside and outside the water tank 8, the third conveying adopts a multi-section independent conveying structure, that is: the third conveying track 6 includes an independent conveying track arranged inside the water tank 8.

[0038] In order to facilitate the setting of the second conveying track 4 and the third conveying track 6 and save space at the same time, the injection molding production line further includes a conveying support 10 arranged longitudinally. The conveying support 10 includes an upper conveying platform 11 and a lower conveying platform 12. The second conveying track 4 is laid on the lower conveying platform 12, and the third conveying track 6 is laid on the upper conveying platform 11; further, baffles are arranged on both sides of the second conveying track 4.
