Activating the hydraulic cylinder causes the telescopic rod to extend and retract, causing the first telescopic mold to extend into or retract into the casting chamber.

[0007] Preferably, a flow channel is provided inside the first telescopic mold, and a connecting nozzle is provided on the side wall of the first telescopic mold, and the connecting nozzle is connected to the flow channel. A refrigerant is injected through the connecting nozzle to cool the corner piece after pouring, thereby facilitating rapid demolding of the corner piece.

[0008] Preferably, a mounting plate is fixedly connected between the rear mold and the rear fixing plate. The mounting plate is used to install a hydraulic motor or a drive motor, and its output end is fixedly connected to a driving gear and meshes with the gear to drive the expansion and contraction of the second telescopic mold.

[0009] Preferably, a countersunk hole is provided on the gear, and a fixing bolt is inserted into the countersunk hole to achieve a fixed connection between the two gears.

[0010] Preferably, a pouring gate is provided in the middle of the front mold, through which material is poured into the pouring cavity.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. Compared with sand casting, the combined mold has higher efficiency and better surface quality of corner parts.

[0013] 2. A flow channel is provided inside the first telescopic mold and a connecting pipe opening is provided on the surface. After the refrigerant is introduced, the cooling process can be carried out quickly, thereby improving the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
