Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0015] Such as figure 1 , 2 An inorganic resin oil heating warming core box shown includes a core box with a sand core cavity 1, the core box includes an upper core box 2 and a lower core box 3, and the upper core box 2 and the lower core box 3 are jointly composed The above sand core cavity 1 is provided with a sand shot hole 4 communicating with the sand core cavity 1 on the upper core box 2 . In this embodiment: several oil heating pipelines 5 are arranged in the core box and around the sand core cavity 1. Generally, the diameter of the oil heating pipelines 5 is 5-30mm, and the oil heating pipelines 5 and the sand core The relative spacing of the cavity 1 is kept at about 10-40mm.

[0016] The core box of the present invention is placed on the bottom frame 6 and connected with the lower top core system 9; the sand shooting hole 4 on the upper core box ...

Abstract

The invention relates to an inorganic resin oil heated warm core box, which comprises a core box with a sand core cavity. The core box comprises an upper core box and a lower core box; the sand core cavity is formed by the upper core box and the lower core box; the upper core box is provided with a sand jet hole communicated with the sand core cavity; and a plurality of oil heating pipelines are arranged at the periphery of the sand core cavity in the core box and are connected with an external oil temperature machine. The core box is heated and cured through the oil heating pipelines, the oil heating pipelines are convenient to arrange, uniform heating is realized, the temperature is controllable, the core box can continuously work, and processing quality is ensured while processing efficiency is improved.

Description

technical field [0001] The invention relates to an inorganic resin oil heating core box. Background technique [0002] Warm core box core making refers to a core making method in which the heating temperature range of the core box is 140-180 ° C, and the use of inorganic water-soluble resin cores has less pollution to the environment, and can be directly placed in water when cleaning castings , so the two are widely used in combination. [0003] At present, the core box generally adopts gas heating to cure the formed sand core, but the gas heating effect is not good, uneven, difficult to control, and it is difficult in continuous production. The quality of the final casting is affected. Contents of the invention [0004] The invention provides an inorganic resin oil heating warming core box, and the applicable heating temperature of the core box is between 120-250°C. [0005] In order to achieve the above object, the technical scheme adopted in the present invention is:...
