[0012] The alignment is inserted into the alignment hole in the upper mold, when the pressing block contacts the top in the alignment hole, the pressing block is retracted into the limiting cylinder under force while the upper mold continues to move downward to the lower mold, the first spring is retracted, the connecting block moves to the lower end of the limiting cylinder together with the pressing block, the connecting rod also moves, drives the arc-shaped plate to expand outward, until the pressing block is completely immersed in the inside of the limiting cylinder, at this time, the outer side of the arc-shaped plate is tightly attached to the inner wall of the alignment hole.

[0013] At the same time, the upper mold enters the notch with the abutting rod and the pressing block, when the upper mold continues to move downward to the lower mold, the pressing block extrudes the inclined surfaces of the two triangular blocks, the two triangular blocks move to both sides under force, the second spring is retracted, the pressing block moves to the lower end of the two triangular blocks, the pressing block contacts the moving block, the two triangular blocks move towards each other under the action of the second spring, until the two triangular blocks contact the abutting rod; at the same time, the upper mold continues to move downward to the lower mold, the abutting rod moves downward with the pressing block against the moving block, drives the connecting rod and the ejector to move downward together, the third spring is retracted, at this time, the ejector is immersed in the ejection groove, until the upper mold and the lower mold are successfully closed.

[0016] The above technical solution, its principle and technical effects:

[0017] In the natural state, the upper end of the pressing block protrudes outside the limiting cylinder, when the lower mold and the upper mold are combined, the correction mechanism is inserted into the corresponding correction hole on the upper mold, as the upper mold continuously moves towards the lower mold, when the pressing block contacts the top in the hole, as the upper mold continues to move towards the lower mold, the pressing block is forced to shrink into the limiting cylinder, the first spring shrinks, and the connecting block moves towards the lower end of the limiting cylinder with the pressing block, in the process of moving, the connecting rod also moves, driving the arc plate to expand outward, until the pressing block completely sinks into the inside of the limiting cylinder, at this time, the outer side of the arc plate is attached to the inner wall of the correction hole, correcting the relative position of the lower mold and the upper mold when they are combined, reducing the positional deviation between the lower mold and the upper mold when they are combined, avoiding excessive error deviation

[0019] When the part casting is completed, the mold is demolded, the upper mold moves away from the lower mold, in the process of moving up the upper mold, due to the lower end of the triangular block against the upper end of the abutting block, the upper mold drives the abutting rod and the abutting block to move up together, at the same time, it drives the moving block, the connecting rod and the ejector to move up together, the upper end of the ejector moves out of the ejection slot, the part of the lower mold is ejected from the casting cavity, until the inclined surface of the triangular block contacts the abutting plate, the two triangular blocks are forced to move to both sides, the second spring shrinks, and the abutting block moves out of the slot between the two triangular blocks.

[0020] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0021] Fixed connection refers to the connection of parts or components after being fixed, without any relative movement. It is divided into detachable connection and non-detachable connection.

[0022] (1) Detachable connection is to fix the parts together by using screws, splines, wedge pins, etc. This connection method can be disassembled during maintenance and will not damage the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolt, key, wedge pin), and the fastening should be appropriate.

[0023] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly is required by forging, sawing, or oxy-acetylene cutting during repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.) when making connections.

[0024] A movable connection is a connection in which two components are joined together, allowing them to maintain relative movement. The connecting component itself is a part of the machine, such as the connection between a bearing and a journal, a cylinder and a piston, or a connecting rod and its body. Attention must be paid to the tolerances of movable connections to ensure the normal operation of the machine.

[0025] The beneficial effects of this invention are:

[0026] 1. The setting of the calibration mechanism: When the upper mold and the lower mold are closed, the calibration mechanism can reduce the relative positional deviation between the upper mold and the lower mold during the mold closing process, so as to avoid excessive deviation and cause the casting to not meet the standard dimensions.

[0027] 2. The ejection mechanism is designed so that when the upper mold separates from the lower mold, the ejection mechanism will automatically eject the casting from the lower mold during the separation process. Attached Figure Description

5. A method of using a mold processing device for parts, characterized in that, Including the part mold processing apparatus as described in claim 4, the specific steps are as follows: When the mold is closed, the motor (540) drives the second bevel gear (541) to rotate, the second bevel gear (541) drives the first bevel gear (531) to rotate, the first bevel gear (531) drives the threaded rod (530) to rotate, and the threaded rod (530) drives the slider (520) to move downward along the third slide groove (511), thereby driving the upper mold (400) to move downward. During calibration, the limiting cylinder (110) is inserted into the calibration hole on the upper mold (400). When the pressing block (142) contacts the top of the calibration hole, as the upper mold (400) continues to move towards the lower mold (300), the pressing block (142) is forced to retract into the limiting cylinder (110), the first spring (150) retracts, and at the same time, the connecting block (143) moves towards the lower end of the limiting cylinder (110) along with the pressing block (142). The connecting rod (160) also moves along with it, causing the arc plate (170) to expand outward until the pressing block (142) is completely submerged in the inner side of the limiting cylinder (110). At this time, the outer side of the arc plate (170) is tightly fitted with the inner wall of the calibration hole. Simultaneously, the upper mold (400), carrying the push rod (410) and the pressing block (411), enters from the slot (311). As the upper mold (400) moves continuously towards the lower mold (300), the pressing block (411) presses against the inclined surfaces of the two triangular blocks (220). The two triangular blocks (220) move to both sides under force, the second spring (230) contracts, and the pressing block (411) moves to the lower end of the two triangular blocks (220). The pressing block (411) contacts the moving block (210), and the two triangular blocks (220) are under the influence of the second spring. Under the action of (230), they move towards each other until the two triangular blocks (220) contact the push rod (410); at the same time, the upper mold (400) is constantly moving towards the lower mold (300), the push rod (410) moves downward against the moving block (210) with the pressing block (411), driving the first connecting rod (240) and the ejector (250) to move downward together, the third spring (260) contracts, at this time the ejector (250) is submerged in the ejection groove until the upper mold (400) and the lower mold (300) are successfully closed; Demolding: The motor (540) drives the second bevel gear (541) to rotate, the second bevel gear (541) drives the first bevel gear (531) to rotate, the first bevel gear (531) drives the threaded rod (530) to rotate, the threaded rod (530) drives the slider (520) to move upward along the third slide groove (511), thereby driving the upper mold (400) to move upward; Ejection: The upper mold (400) moves the push rod (410) and the pressing block (411) upward together. At the same time, it moves the moving block (210), the first connecting rod (240) and the ejector (250) upward together. The upper end of the ejector (250) moves out of the ejection groove and ejects the casting from the part casting cavity of the lower mold (300) until the inclined surface of the triangular block (220) contacts the baffle plate (312). The two triangular blocks (220) are forced to move to both sides, the second spring (230) contracts, and the pressing block (411) moves out of the groove (311) from between the two triangular blocks (220).
