Embodiment Construction
[0040] 1. According to Figure 1~4 The specific structure of the present invention will be described in detail.
[0041] The special radiator for CNC milling machine motor includes connecting rod 2, heat sink 5, radiator main body 1, and cast exhaust hole column 4. A semi-cylindrical bolt hole 3 is arranged behind the end surface of the radiator main body 1 in contact with the connecting rod 2. The rod 2 and the semi-cylindrical bolt hole 3 connect the radiator main body 1 to the motor of the CNC milling machine. The cooling fins 5 are located on both sides of the all-aluminum radiator main body 1, and the cooling fins on one side have a cast vent post 4.
[0042] The mold of the whole CNC milling machine motor special radiator is divided into two half-moulds, a movable mold and a fixed mold, and the movable mold and the fixed mold are respectively provided with cavities, and the mold cavities are designed according to the corresponding half of the interface 15 of the radiator...

Disclosed is a casting die for a special radiator of a numerically-controlled milling machine. The casting die for the special radiator of the numerically-controlled milling machine is integrally divided into two half dies, namely a moving die and a fixed die, the moving die and the fixed die are respectively provided with a cavity, and the cavities are designed to corresponding halves according to an interface of the radiator. Two sides of the moving die are respectively provided with a backward-pulling plates used for separating the moving die from the fixed die, the moving die and the fixed die are fixed on a casting machine through support plates, and a flying ring used for conveniently hoisting the dies is arranged at top ends of the moving die and the fixed die. Compared with a cast-iron radiator, the special radiator cast from total aluminum by the die is lighter. Compared with radiators made of current universal punch forming and investment casting molding processes, the special radiator is high in precision, smooth in surface and high in radiating efficiency.
Description
technical field [0001] The invention relates to a radiator casting mold. Background technique [0002] Precision casting is a special casting. Parts obtained by this method generally do not need to be machined. Such as investment casting, pressure casting, etc. Investment casting is a casting method relative to the traditional casting process. It can obtain relatively accurate shape and high casting precision. The more common method is: first design and manufacture the mold according to the product requirements (with a very small or no allowance), cast wax by casting method to obtain the original wax pattern; repeat coating and sanding on the wax pattern process, hardening the shell and drying; then melting the internal wax pattern for dewaxing to obtain the cavity; roasting the shell to obtain sufficient strength; pouring the required metal materials; clearing the sand after shelling, so as to obtain High-precision finished products. According to product needs or heat...
