[0019] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0020] Figures 1-3 The utility model discloses a whole structure schematic diagram of an engine cylinder liner production mold, please refer to Figures 1-3 The utility model discloses an engine cylinder liner production mold, including lower mould 100, the inside central part of lower mould 100 has the cylinder column 110, the inside of cylinder column 110 has the forming column 120 with its same axis, and the periphery side between cylinder column 110 and forming column 120 has the casting groove 130, and the inside of lower mould 100 still has the cooling cavity 140 that surrounds cylinder column 110, and the bottom of lower mould 100 has a plurality of limit guide bushings 160 that are communicated with the bottom of casting groove 130, and the inside of limit guide bushing 160 is vertically slidably matched with the top die bar 200, and the bottom of top die bar 200 is fixed with the mounting disc 210, and the bottom disc 220 is below the mounting disc 210, and a plurality of elastic members 230 are connected between the bottom disc 220 and the mounting disc 210, and the mounting disc 210 still is provided with vibrator 240, and the bottom disc 220 is driven to move up and down by the hydraulic rod one 250 arranged below, and the upper mould 410 that the lifting frame 400 is also matched with the upper side of lower mould 100 and is arranged at the bottom of lifting frame 400.

[0021] The utility model discloses a whole structure schematic diagram of an engine cylinder liner production mold, please refer to Figures 1-3 The inside of cooling cavity 140 still is provided with the spiral cooling pipe 150 that is wound in the periphery side of cylinder column 110 along its height direction, and the outside of lower mould 100 still has the liquid inlet and liquid outlet corresponding with the two ports of spiral cooling pipe 150 respectively, and can understand, and spiral cooling pipe 150 is connected with the refrigeration equipment such as compressor or water chiller through liquid inlet and liquid outlet, so that cooling liquid circulates, and specifically, when the engine cylinder liner mold in casting groove 130 is shaped, the cooling equipment is opened at random, and cooling liquid circulates through spiral cooling pipe 150, and the heat on cylinder column 110 and cylinder liner is taken away, plays the effect of heat exchange and cooling, is favorable to the surface microcontraction of cylinder liner and subsequent stripping.

[0022] The top die rod 200 is evenly distributed along the bottom of the casting groove 130, and the elastic member 230 is evenly distributed along the bottom plate 220. In the normal mold, the top of the top die rod 200 is flush with the bottom of the casting groove 130, and only when the mold is removed, the top die rod 200 is pushed out of the bottom of the casting groove 130. In addition, it can be understood that the elastic member 230 here can be a high-strength spring, a spring damper, a hydraulic damper, etc. The lifting frame 400 is vertically slid through the guide column 420 fixed to the top of the lower mold 100, and the guide column 420 is fixed to the top plate 430, and the hydraulic rod two 440 is arranged at the upper end of the top plate 430, and the bottom output shaft of the hydraulic rod two 440 is connected to the top of the lifting frame 400.
