Description

Mould loading system

Technical Field

The invention belongs to the technical field of machinery, and relates to a mold loading system.

Background

Mould heat treatment is of greatest use for mould manufacture to further improve the accuracy of the mould, such as preventing thermal oxidation and non-decarburisation, vacuum degassing or outgassing, eliminating hydrogen embrittlement, and thereby improving the plasticity, toughness and fatigue strength of the material. Therefore, the molds of the prior art are basically subjected to a heat treatment process, and a heat treatment plant usually allows a transport driver to go to the mold plant, transport the molds back to the plant for processing, and transport the molds back to the mold plant after the heat treatment. However, for a large-sized male die, when the male die is loaded, a sucker is usually used for sucking the side edge of the male die, then a travelling crane is used for hoisting the male die to the travelling crane through the sucker, at the moment, the die is in an upright state, the sucker is taken down, and finally the male die is pushed down to complete loading.

However, the mold loading method has the following defects:

1. the center of gravity of the male die is usually inclined to the side edge, so that large manual thrust is needed when the male die is laid down and the bottom surface of the male die is attached to a vehicle;

2. the side area of the male die is small, the adsorbable area of the sucker is small, and dust, scrap iron and water drops are easily adhered to the sucker in a workshop, so that the magnetism between the sucker and the die is influenced, the die is easily dropped in the transportation process, operators are injured by crashing or the die is damaged;

3. when the mold is pushed down on a vehicle, the impact force is very large, which not only causes great abrasion to the vehicle, but also generates great noise.

The invention aims to provide a mould loading system aiming at the problems in the prior art, and the technical problems to be solved by the invention are as follows: how to improve the security when large-scale mould loading, reduce the impact to the freight train.

The purpose of the invention can be realized by the following technical scheme:

the utility model provides a mould loading system, set up screw hole one on the mould, a serial communication port, the loading system includes bolt ring, couple, driving and bottom plate, bolt ring can with a screw hole threaded connection on the mould, the lower extreme and the bolt ring looks lock joint of couple, the upper end and the driving looks lock joint of couple, the bottom plate can be fixed in on the carriage of car, the bottom plate is equipped with a plurality of draw-in groove along self length direction and width direction interval, the scarf joint has the cushion on the draw-in groove, the upper surface of cushion is higher than the last face of bottom plate.

The working principle is as follows: when the die is installed on a carriage of an automobile, the bolt ring can be screwed into the first threaded hole of the die, and the large die can be provided with the threaded hole on the die due to process requirements, so that only the corresponding bolt ring needs to be selected according to the threaded hole, and the die does not need to be additionally improved. After the bolt ring is installed, the upper end and the lower end of the hook are respectively buckled with a travelling crane and the bolt ring in a workshop, then the travelling crane is started, the mold is hung on a carriage, and the front end of the lower side surface of the mold is aligned to one cushion block; a descending button of the travelling crane is operated to drive the mould to descend, so that the front end of the lower side surface of the mould is abutted against the rear edge of the upper surface of the cushion block, the rear end of the lower side surface of the mould is abutted against the rear side surface of the cushion block or a carriage, and the mould has the tendency of backward inclination; the back button and the descending button of the traveling crane are alternately and repeatedly pressed, and the mold has the tendency of backward inclination, so that the bottom surface of the mold can gradually descend until the bottom surface is attached to the bottom plate under the action of gravity. The loading system has the advantages that the advantages can be more obvious when the male die is loaded, and because the center of gravity of the male die moves forwards when the male die is hoisted, the flat bottom surface of the male die is difficult to be attached to a carriage, and the convex surface which is protruded usually is attached to the carriage, so that the die is easy to shake and move in the transportation process; in the design, the cushion block is designed, so that the front side of the lower end surface of the die or the lower end surface of the convex part of the male die and the rear edge of the upper surface of the cushion block can change the forward tilting state of the male die into the backward tilting state under the action of the cushion block, and further, when the male die is finally put down, the flat bottom surface of the male die is attached to the bottom plate of a carriage, and the male die is prevented from shaking during transportation. Because the design has a plurality of draw-in grooves on the bottom plate, can select corresponding cushion to be used for pushing up the mould according to actual conditions when consequently loading, and other cushion that probably lean on with the mould bottom surface are pulled down, guarantee that the whole bottom surface homoenergetic of mould can be leaned on mutually with the carriage bottom plate.
