Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mold base processing, and more particularly to an automatic heat treatment device for mold base processing. BACKGROUND

[0002] The mold base is the skeleton of the mold, and its function is to install and fix the core components of the mold (such as the core, cavity, slider, etc.). In modern manufacturing industries such as plastic injection, die casting, and stamping, the quality of the mold base directly determines the precision, service life, and production stability of the final mold. Heat treatment is a crucial process in mold base processing, and its core purpose is to change the internal metallographic structure of steel through heating, holding, and cooling to obtain the required hardness, strength, wear resistance, toughness, and dimensional stability. For mold bases, especially medium and large mold bases, uniform and controllable heat treatment is the key to avoiding deformation, cracking, and premature wear during use.

This not only has high labor intensity and low efficiency, but also has a high-temperature and high-risk working environment, which is prone to scalding, bruising, and other safety accidents. Moreover, manual control of heating temperature, holding time, and quenching medium stirring and cooling speed has poor stability and repeatability.

[0064] Embodiment two

[0065] In actual use, it is found that in order to avoid the third motor 6024 entering the quenching liquid, the vertical plate 7 and the third motor 6024 need to be arranged at a high position of the second pull rod 6015, so that after the mold frame enters the quenching solution with the supporting platform 401, the third motor 6024 is still located above the liquid level, which will cause the third sprocket 6027 on the third motor 6024 to have a large distance with the third sprocket 6027 on the supporting platform 401, and the third chain 6028 has a long length and is easy to deform under the action of gravity, which will affect the meshing effect of the third chain 6028 and the plurality of third sprockets 6027.

[0066] Please refer to Figure 7 and Figure 10 As shown in the drawings, two symmetrical transverse grooves 8 are formed in the vertical plate 7, and a pressing rod 9 is transversely and slidably connected in each of the two transverse grooves 8.

[0067] On the basis of the above embodiment, when the staff finds that the third chain 6028 is loose during use, the limiting cylinder 11 can be counterclockwise rotated to make the limiting cylinder 11 disengaged from the vertical plate 7. At this time, the pressing rod 9 can freely move in the transverse groove 8.
