A drying device for mold shells

Abstract

This utility model relates to the field of mold shell drying technology, specifically disclosing a mold shell drying device, including a support mechanism for providing a drying chamber. The support mechanism includes a drying box, with a box cover rotatably mounted on the front end of the drying box. A support grate is fixed at a lower position inside the drying box. The support mechanism is equipped with a drying mechanism for intermittently rotating and drying the placed mold shell on its outer ring. The drying mechanism includes a mounting bracket fixed to the rear wall of the drying box. Through the intermittent rotation component and the drying component of the drying mechanism, the power component drives the connected rotating shaft to rotate. The transmission gears on the two rotating shafts mesh and rotate, causing the semi-circular gear on the rotating shaft to rotate. The semi-circular gear and the driven gear between the semi-circular gears alternately mesh, causing the driven gear and the support shaft to reciprocate alternately in forward and reverse directions. When the support shaft rotates, it drives the drying component to rotate, forming a reciprocating drying process on the outside of the mold shell, thus improving the drying efficiency of the mold shell.

Description

Technical Field

[0001] This utility model relates to the field of mold shell drying technology, and in particular to a mold shell drying device. Background Technology

[0002] An existing drying device for mold shells, with publication number CN 213317518 U, involves placing the mold shell on the outside of support rods, which then move outwards to push and fix the mold shell. Hot air is then delivered to a heating chamber by a hot air blower. Combined with heating wires within the chamber, the hot air temperature rises again and flows into the inner cavity of the chamber through ventilation holes, effectively drying the mold shell. An exhaust fan further enhances airflow circulation within the chamber. However, this drying device primarily heats the inner cavity of the chamber through ventilation holes, resulting in relatively low drying efficiency and causing production problems. Utility Model Content

[0003] The purpose of this invention is to provide a drying device for mold shells in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-5 As shown, a drying device for mold shells includes a support mechanism for providing a drying chamber. The support mechanism includes a drying box 11, a box cover 12 is rotatably installed at the front end of the drying box 11, and a support grate 13 is fixed at a lower position inside the drying box 11. The support mechanism is provided with a drying mechanism for intermittently rotating and drying the placed mold shells in an outer ring.

[0024] In this embodiment: the drying mechanism includes a mounting frame 21 fixed to the rear wall of the drying chamber 11. A drying assembly is provided inside the drying chamber 11. An intermittent rotating assembly for reciprocating intermittent rotation of the drying assembly is provided on the mounting frame 21. The intermittent rotating assembly includes a support shaft 22 located at the center of the rear wall of the drying chamber 11. A driven gear 28 is mounted at the rear end of the support shaft 22. Rotating shafts 25 are provided on both sides of the support shaft 22 on the mounting frame 21. A transmission gear 26 meshes with each other and a semi-circular gear 27 alternately meshes with the driven gear 28 is mounted on the rotating shaft 25. A reduction motor 29 is connected to the rear end of one of the rotating shafts 25. 2 is rotatably connected to the drying chamber 11, and the rotating shaft 25 is rotatably connected to the drying chamber 11 and the mounting bracket 21; the semi-circular gear 27 and the transmission gear 26 are both fixedly connected to the rotating shaft 25; the rotating shaft 25 is driven to rotate by the operation of the reduction motor 29, and the transmission gear 26 on the two rotating shafts 25 rotates after meshing, causing the semi-circular gear 27 on the rotating shaft 25 to rotate, and alternately meshing with the driven gear 28 between the semi-circular gear 27, causing the driven gear 28 and the support shaft 22 to reciprocate alternately forward and reverse. When the support shaft 22 rotates, it drives the drying component to rotate, forming a reciprocating drying process on the outside of the mold shell, which improves the drying efficiency of the mold shell.

[0025] The drying assembly includes a turntable 23 fixed on a support shaft 22. The turntable 23 is located inside the drying chamber 11. A drying air duct 24 is provided on the turntable 23 near its edge. A connecting pipe is provided at the rear end of the drying air duct 24.

At least three drying air ducts 24 are distributed in an arc shape on the turntable 23, and the ends of the drying air ducts 24 are all connected through a pipe body. When the intermittent rotation assembly is working, it drives the drying air ducts 24 on the turntable 23 to reciprocate on the outer wall of the mold shell. The drying hot air blown out of the drying air ducts 24 accelerates the drying of the module.

[0026] The working principle and usage process of this utility model are as follows: The mold shell is placed on the support grate plate 13, the box cover 12 is closed, and the hot air source connected to the drying air duct 24 is turned on. The reduction motor 29 drives the connected rotating shaft 25 to rotate. The transmission gears 26 on the two rotating shafts 25 mesh and rotate, causing the semi-circular gear 27 on the rotating shaft 25 to rotate. The driven gear 28 between the semi-circular gear 27 meshes alternately, causing the driven gear 28 and the support shaft 22 to reciprocate alternately forward and reverse. In turn, the support shaft 22 drives the drying air duct 24 on the turntable 23 to perform reciprocating drying treatment on the outer wall of the mold shell, thereby improving the drying efficiency of the mold shell.
