Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a cylinder die-casting mold. Background Art

[0002] The engine cylinder block die-casting mold usually consists of an upper mold and a lower mold. The metal pressure casting technology is used to inject molten metal (such as aluminum alloy) into the mold, and the engine cylinder block is formed after cooling and solidification.

[0003] Chinese patent publication number CN220462170U discloses an engine cylinder die-casting mold, comprising a lower base, an upper base, and two sets of die-casting mold bodies that can be molded together, wherein the upper base and the lower base are connected by guide pillars, and the surfaces of the lower base and the upper base are respectively provided with a lower mold and an upper mold. The utility model provides a receiving cavity for accommodating the die-casting mold body inside the lower mold, and a driving component for pre-opening the die-casting mold body is provided between the lower base and the lower mold. The driving component can be provided to drive the die-casting mold body to descend inside the receiving cavity, thereby opening the die-casting mold body with the die-casting mold body inside the upper mold, and after the two sets of die-casting mold bodies are opened, the support component can be further moved to open the upper mold and the lower mold again, thereby separating the opening between the two sets of die-casting mold bodies and between the upper mold and the lower mold, thereby facilitating the overall opening.

[0004] In the above-mentioned prior art, the movement of the die-casting mold body is controlled to assist in the opening of the upper mold and the lower mold, thereby improving the mold opening effect. However, during the die-casting production of the engine cylinder block, the melting point, fluidity and other properties of the casting material may affect the adhesion between it and the mold. For example, casting materials with a lower melting point are more likely to adhere to the mold during the die-casting process, which will affect the smoothness of the mold opening and the demolding of the casting.

[0054] In order to facilitate the demolding of the finished cylinder body in the die-casting mold body 2, a spraying structure for spraying a release agent onto the die-casting mold body 2 in the base 1 is arranged on one side of the base 1, and a driving structure for controlling the movement and spraying of the spraying structure is arranged on the spraying structure.

[0055] Among them, the spraying structure includes a storage box 3 arranged on one side of the base 1 for storing the release agent, a delivery pump 301 arranged on one side of the storage box 3, the liquid suction end of the delivery pump 301 penetrates into the storage box 3, a delivery pipe 302 arranged on the infusion end of the delivery pump 301, a diversion pipe 303 arranged at one end of the delivery pipe 302 and connected to the delivery pipe 302, a nozzle 304 arranged on the diversion pipe 303 for spraying the release agent, a sliding frame 305 arranged on the diversion pipe 303, and a fixed frame 306 arranged on the base 1 for supporting the sliding frame 305.

[0063] Working principle:

[0064] After the mold is opened, the multi-stage electric push rod 4 and the delivery pump 301 are turned on. The delivery pump 301 can extract the release agent in the storage box 3 and deliver it to the diversion pipe 303 through the delivery pipe 302, and finally spray it on the surface of the base 1 through the nozzle 304. During the process, the output end of the multi-stage electric push rod 4 will push the linkage plate 402 to move, and the moving linkage plate 402 will drive the linkage shaft 407 to move in the linkage sliding hole 406. At the same time, the linkage shaft 407 will squeeze the linkage sliding hole 406 and flip one end of the movable link 1 403, so that the movable link 1 403 rotates on the movable link 2 404 and drives one end of the movable link 2 404 to move. The other end of the movable link 2 404 will rotate above the connecting bar 405 and push the connecting bar 405 to move. The moving connecting bar 405 can drive the sliding The movable frame 305 moves, and the continuously moving sliding frame 305 can drive the diversion pipe 303 and the nozzle 304 to move above the base 1, so that by controlling the extension and contraction of the output end of the multi-stage electric push rod 4, the nozzle 304 can be moved back and forth above the base 1, and the release agent is evenly sprayed in the die-casting mold body 2 in the base 1, and during the movement of the connecting bar 405, the liquid-absorbing sponge 5 can be driven to move. The liquid-absorbing sponge 5 can contact the surface of the base 1 and absorb the excess release agent sprayed on the surface of the base 1, that is, around the die-casting mold body 2. When the liquid-absorbing sponge 5 moves back, it will be squeezed by the extrusion plate 502, and the released agent adsorbed by it will be squeezed out. The extruded released agent can fall into the liquid receiving funnel 501 and then flow into the storage box 3 through the liquid receiving funnel 501. The excess release agent can be recovered and reused to reduce waste.
