Description

Technical Field

[0001] This utility model relates to the field of sintering technology, and in particular to a workpiece sintering device for metal powder injection molding. Background Technology

[0002] Sintering is one of the main methods for agglomerating iron (concentrate) ore powder that cannot be directly added to a blast furnace. Sintering also improves the metallurgical properties of the raw materials. Sintering is also applied in non-ferrous metal smelting processes; in addition to agglomeration, sintering of non-ferrous metal sulfide concentrates also has a desulfurization effect. Heat treatment of metal workpieces at temperatures below the melting points of their main components aims to improve their strength through metallurgical bonding between particles.

[0003] In modern manufacturing, metal powder injection molding technology is widely used in aerospace, medical devices, and electronic communications due to its ability to produce complex-shaped, high-precision metal parts. However, most metal powder injection molding workpiece sintering devices currently adopt a split design, dispersing degreasing, sintering, and cooling processes into different devices for independent completion. The frequent transfer of workpieces between multiple devices not only significantly extends the processing cycle but also increases the risk of workpiece contamination and damage. To address these issues, we propose a workpiece sintering device for metal powder injection molding. Utility Model Content

[0004] The purpose of this invention is to provide a workpiece sintering device for metal powder injection molding, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] In a further embodiment, the front of the device body is provided with a discharge port, the inner wall of the discharge port is hinged with a sealing door, the front of the sealing door is connected with a handle, and the left side of the device body is provided with a feed port, the inner wall of the feed port is hinged with a protective door.

[0008] In a further embodiment, the inner wall of the conveying mechanism is connected to a conveying chain, one end of the conveying mechanism passes through the feed inlet and extends to the outside of the device body, and the bottom surface of the conveying mechanism is connected to two support legs.

[0009] In a further embodiment, a carrier plate is provided above the conveyor chain, and a material box is snapped into the inner wall of the carrier plate.

[0010] In a further embodiment, the exhaust gas treatment mechanism includes a ventilator connected to the back of the device body. The input end of the ventilator is connected to a first ventilator pipe, a second ventilator pipe, and a third ventilator pipe. The ends of the first, second, and third ventilators away from the ventilator all penetrate the device body and extend into the interior of the device body.

[0011] In a further embodiment, three potentiometers are connected to the inner top wall of the device body, and a temperature sensor is connected to the bottom surface of each potentiometer.

[0012] In a further embodiment, each of the seals includes an electric slide connected to the top wall of the device body, and a sealing partition is slidably connected to the inner wall of each electric slide. The inner wall of the device body is provided with two sets of limiting slide grooves, and each sealing partition is slidably connected to the limiting slide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device integrates degreasing, sintering, and cooling processes into its main body. Combined with the orderly transport of the conveyor mechanism, it avoids the need for workpieces to be transferred between multiple devices, significantly shortening the processing cycle, improving production efficiency, and reducing the risk of contamination and damage during workpiece transfer. Simultaneously, the potentiometer and temperature sensor work together to accurately monitor and control the sintering zone temperature in real time. Combined with effective isolation of each functional area by sealing components, it ensures a stable sintering process, effectively reducing quality problems such as workpiece cracks and deformation, and improving product qualification rate and consistency. Utilizing the exhaust gas treatment mechanism's air exchanger and multiple sets of air exchange pipes, it can promptly collect and purify the exhaust gas generated during the degreasing process, meeting environmental protection requirements and reducing environmental pollution. Furthermore, the sealed design of the inlet and outlet ensures the stability of the internal working environment of the device, further improving processing quality and equipment operational reliability.
