Description

Technical Field

[0001] The invention relates to the technical field of heating furnaces, and in particular to a heating furnace for urea-formaldehyde powder materials. Background Art

[0002] Urea-formaldehyde powder plastics are widely used in the manufacture of parts for daily electrical appliances, electrical instruments, cultural and educational supplies, etc. In recent years, with the improvement of people's living standards, urea-formaldehyde powder plastics are used to make toilet seats. Urea-formaldehyde plastic is a plastic made of urea-formaldehyde resin as the basic component. It is a thermosetting plastic. Urea-formaldehyde powder plastic moldings are usually molded by compression molding. Urea-formaldehyde powder is added to the molding die for heating and pressure molding. Before compression molding, the urea-formaldehyde powder is usually required to have a certain initial temperature to avoid the problem that the internal temperature of thicker parts does not meet the standard when heated in the mold and the external temperature is excessively heated, resulting in excessive deformation of the molded urea-formaldehyde toilet seat cover; the current urea-formaldehyde powder material heating furnace is not convenient for wind-powered anti-adhesion heating. Urea-formaldehyde powder is easy to adhere, and its powder particles are not completely consistent, which is not convenient for separation and heating. It is very easy to cause small particles to be overheated and large particles to be incompletely heated, affecting the subsequent compression molding quality. At the same time, it is not convenient to add urea-formaldehyde powder more directly to the mold. Manual operation is required to put it into the mold. The control accuracy of the added amount is poor, which is easy to cause waste. The temperature of the urea-formaldehyde powder will also be lost during transportation. Excessive deformation of the urea-formaldehyde toilet seat cover will also increase the subsequent trimming and shaping process. Summary of the invention

The discharge piece 6 used can be matched with the emission control piece 7 to block the outside, improve the discharge accuracy, and avoid excessive emission of urea-formaldehyde powder. The emission control piece 7 can be attached to the lower die 204 of the molding die to avoid excessive emission. In order to prevent urea-formaldehyde powder from leaking, dust can be reduced, and waste caused by excessive urea-formaldehyde powder causing large flash on molded parts can be reduced. The lifting control inclined block 705 can control the support cylinder 704 to automatically lift and lower. Through the extrusion of the support spring 703, the support cylinder 704 can be driven to stick to the top surface of the upper surface of the mold mounting frame 202 to perform a fitting and sealing operation to avoid leakage caused by the impeller 302 blowing. The support cylinder 704 can be used to directly and quickly discharge the urea-formaldehyde powder to the lower mold 204 of the molding mold to reduce heat loss, and also prevent environmental impurities from mixing into the urea-formaldehyde powder to cause defects after molding.

[0040] The working principle of this embodiment is as follows: after the lower die 204 of the molding die is installed on the molding press, the lower die 204 of the molding die is installed under the upper die, and the shielding cover 104 is rotated to open, and the urea-formaldehyde powder is introduced into the feed pipe 103, and the driving motor 301 drives the impeller 302 to rotate to generate wind force.

At this time, the support cylinder 704 is also driven to move, and the support spring 703 is used to squeeze the support cylinder 704 to stick to the lower mold 204 of the molding mold. The discharging motor 601 drives the discharging auger 602 to rotate for discharging, and the spiral structure is used to realize pressurized discharging.

Under the extrusion guidance of the inclined surface, the support cylinder 704 is driven to move upward. As the driving hydraulic cylinder 203 continues to drive, the support cylinder 704 can be driven to stick to the upper surface of the mold mounting frame 202, and the extrusion of the support spring 703 is cooperated to perform elastic fitting and extrusion work, and the support cylinder 704 is blocked again.
