Description

Technical Field

[0001] The utility model relates to the technical field of preheating furnaces, in particular to a track-type mold preheating furnace. Background Art

[0002] Some molds can only work after reaching a certain temperature, so the structure of the mold preheating furnace is introduced. Generally speaking, the mold is preheated by ignition. During preheating, the mold is placed in the radiation range of the heat after ignition to heat up to the set temperature;

[0003] For some larger molds, it is not easy to put the molds into the preheating furnace for heating because the molds are large and have heavy gravity. Therefore, the existing technology uses a trolley to drive the mold to move into the furnace body. At the same time, the existing technology uses a hook to connect two trolleys, so that multiple trolleys can drive multiple molds into the furnace body for preheating. However, since most of the existing trolley hooks are manually hung together, when the mold is preheated, the temperature on the trolley and the hook is also high, which makes it difficult to separate the adjacent trolleys later. Therefore, it is necessary to design a new track-type mold preheating furnace to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a track-type mold preheating furnace is proposed. The preheating furnace is provided with a limit block and a blocking ring, so that after the mold preheating is completed, when multiple mobile carts drive the mold out, the first hook and the second hook are automatically separated, thereby eliminating the need for manual separation of the mobile cart, and through the provision of a threaded rod and a threaded sleeve, the blocking ring can be removed when the mobile cart enters the furnace body, thereby avoiding the situation where the mold enters the preheating furnace and causes an impact, and at the same time, through the provision of a scraper, the particulate matter in the rolling groove can be cleaned, thereby avoiding the situation where the mobile cart runs unstable.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4 , a track-type mold preheating furnace, comprising a furnace body 1 installed above the ground, a mobile car 4 is provided on the right side of the furnace body 1, a plurality of mounting blocks 5 are fixedly connected to the lower end of the mobile car 4, adjacent sides of each two matching mounting blocks 5 are connected to a rotating shaft 6 for common rotation, two rotating shafts 6 are fixedly connected to two rollers 7, two rolling grooves 3 are provided on the ground, a plurality of rollers 7 are rollingly connected to the inner bottom of the corresponding rolling grooves 3, a fixed block 8 is installed at the lower end of the mobile car 4, a driving motor 9 is installed on the fixed block 8, the output shaft of the driving motor 9 is connected to the rotating shaft 6 on the right side through a transmission assembly 10, the transmission assembly 10 includes a sprocket arranged on the output shaft of the driving motor 9 and the rotating shaft 6, and the two sprockets are connected through a chain transmission;

[0024] It should be noted that when the drive motor 9 rotates clockwise, the moving vehicle 4 moves left, and when the drive motor 9 rotates counterclockwise, the moving vehicle 4 moves right, thereby being able to move the mold into the furnace body 1 or move the mold from the furnace body 1 to the outside.

[0025] The lower end of the mobile vehicle 4 is fixedly connected with a second hook 21, the lower end of the mobile vehicle 4 is fixedly connected with two vertical rods 11, the adjacent sides of the two vertical rods 11 are connected with a rotating rod for common rotation, the rotating rod is fixedly connected with a first hook 12 matched with the second hook 21, the lower end of the first hook 12 is fixedly connected with a cylinder, the right side of the cylinder is fixedly connected with a limited block 13, and the rotating rod is elastically connected to the vertical rod 11 located on the right side through a torsion spring;

[0026] It should be noted that the first hook 12 is located on the right side of the moving vehicle 4, and the second hook 21 is located on the left side of the moving vehicle 4. The right side of the first hook 12 is an inclined surface, so that the first hook 12 and the second hook 21 can make adjacent moving vehicles 4 hooked together and move synchronously.

[0027] Among them, a blocking ring 20 is provided above the ground, a threaded sleeve 18 is embedded in the ground, a threaded rod 19 is connected to the threaded sleeve 18, and the lower end of the blocking ring 20 is fixedly connected to the upper end of the threaded rod 19;

[0028] It should be noted that when the mobile vehicle 4 moves to the left, the blocking ring 20 will not be located on the ground. When the mold is preheated, the staff can install the blocking ring 20 on the ground by rotating the threaded rod 19 clockwise, so that when the mold moves to the right, the adjacent mobile vehicles 4 will be separated.

[0029] Among them, lifting doors 2 are arranged on the left and right sides of the furnace body 1 , and two electric telescopic rods 16 are fixedly connected to the upper end of the furnace body 1 . The telescopic ends of the two electric telescopic rods 16 are commonly fixedly connected to a rectangular plate 17 , and the two rectangular plates 17 are fixedly connected to the lifting doors 2 .

[0030] The lower end of the moving vehicle 4 is fixedly connected to two pneumatic rods 14 , and the telescopic ends of the two pneumatic rods 14 are fixedly connected to scrapers 15 , and the two scrapers 15 are slidably connected to the inner wall of the rolling groove 3 .

[0031] The functional principle of the utility model can be explained through the following operation mode: when the mold is preheated, the rollers 7 on the multiple moving carts 4 are first placed in the corresponding rolling grooves 3, and then the two adjacent moving carts 4 are relatively moved. Since the right side of the first hook 12 is an inclined surface, when the first hook 12 contacts the second hook 21, the first hook 12 will rotate downward. As the two adjacent moving carts 4 continue to move, the first hook 12 will rotate under the action of the torsion spring, so that the first hook 12 and the second hook 21 are hooked together;

[0032] At this time, the drive motor 9 located on the last moving vehicle 4 can be started, so that the output of the drive motor 9 rotates clockwise, so that the multiple molds are moved into the furnace body 1 for preheating. When the molds enter the furnace body 1, the multiple electric telescopic rods 16 are controlled to be compressed, so that the lifting door 2 moves down and the furnace body 1 door is closed. At this time, the molds can be preheated;

[0033] When preheating is completed, the staff can open the lifting door 2 and then control the drive motor 9 on the rightmost moving vehicle 4 to operate, so that the mold can be transported out of the furnace body 1. When preheating the mold, the staff can install the blocking ring 20 on the ground, so that when the moving vehicle 4 moves to the right, when the limit block 13 contacts the blocking ring 20, the limit block 13 drives the sleeve to rotate upward, so that the first hook 12 rotates downward, so that the first hook 12 is separated from the adjacent second hook 21, so that the rightmost moving vehicle 4 is separated from the adjacent moving vehicle 4, and then the corresponding drive motors 9 are controlled to operate from right to left in turn, so that each moving vehicle 4 is separated from the adjacent moving vehicle 4;

[0034] When the mobile vehicle 4 moves into the furnace body 1, the pneumatic rod 14 is in a retracted state. When the mobile vehicle 4 moves to the right, the staff can control the multiple pneumatic rods 14 to stretch, so that the scraper 15 contacts the inner bottom of the rolling groove 3, so that the scraper 15 can clean the rolling groove 3 to avoid impurities affecting the movement of the mobile vehicle 4.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
