Description

Technical Field

[0001] This utility model relates to the field of shell mold technology, and more specifically, to a shell mold used in casting production. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and other methods. Casting molds are a type of mold, generally formed by casting. To avoid voids or missing parts in the injected material, pressurization is usually used to improve the integrity of the injection molding. However, in the use of existing pressurized casting molds, most casting molds are directly fixed on the casting device, making it inconvenient to disassemble the casting mold and causing great inconvenience when maintaining or replacing it. Therefore, a pressurized casting mold for shell casting is proposed.

[0003] To address the aforementioned issues, patent document publication number CN222403342U discloses a pressure-boosting casting mold for shell casting, comprising a base and an upper mold. The base has two support feet on each of its left and right bottom sides, and columns on each of its left and right top sides. This pressure-boosting casting mold for shell casting uses two first handwheels to move two first positioning blocks in opposite directions, causing the two first positioning blocks to move out of their respective first positioning slots. At this point, the upper mold can be pulled downwards to disassemble it.

[0004] However, it still has some drawbacks in actual use. For example, when the mold is used, the huge pressing force generated by the die-casting machine will cause a large friction between the shell and the mold after the casting is completed, making it difficult to remove the shell from the mold.

[0005] Therefore, a shell mold for casting production was proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a shell mold for casting production, so as to solve the problem that when the existing mold is used, the huge pressing force generated by the die casting machine causes the shell to generate a large friction force between the shell and the mold after casting, making it difficult to remove the shell from the mold.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a shell mold for casting production, comprising...

[0008] Lower mold;

[0009] A support column, the bottom end of which is fixedly connected to the top of the lower mold;

[0010] A top plate, the bottom of which is fixedly connected to the top of a support column;

[0011] An automatic feeding assembly is disposed below the top plate;

[0012] The upper mold, the top of which is fixedly connected to the bottom of the automatic unloading assembly;

[0013] The automatic feeding assembly includes a hydraulic rod, a top column, and a spring. The top end of the hydraulic rod is fixedly connected to the bottom of the top plate. The bottom end of the top column is slidably connected to the inside of the upper mold. A connecting plate is fixedly installed on the top end of the top column. The top end of the spring is fixedly connected to the bottom of the connecting plate. The bottom end of the spring is fixedly connected to the top of the upper mold. A stop pin is fixedly installed on the top of the connecting plate. A force-bearing plate is fixedly installed on the bottom of the top plate.

[0014] It also includes a cleaning component, which is disposed on the back side of the lower mold.

[0015] The cleaning assembly includes a support plate and a moving mechanism. A fan is fixedly installed on the top of the support plate. A collection box is fixedly connected to the exhaust end of the fan. A filter screen is installed at the connection between the fan and the collection box. A connecting hose is fixedly connected to the side of the collection box away from the fan. A dust suction port is fixedly connected to the end of the connecting hose away from the collection box. The moving mechanism is installed on the top of the lower mold. The top of the moving mechanism is fixedly connected to the bottom of the dust suction port.

[0016] The moving mechanism includes a slide groove, a motor is fixedly installed at one end of the slide groove, a lead screw is rotatably installed inside the slide groove, one end of the lead screw is fixedly connected to the output end of the motor, a slider is slidably installed inside the slide groove, the inside of the slider is threadedly connected to the outer surface of the lead screw, a support frame is fixedly connected to the top of the slider, and the top of the support frame is fixedly connected to the bottom of the suction port.

[0017] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0018] In the above scheme, a lower mold, support column, top plate, automatic feeding component, and upper mold are set. The upper mold is driven to descend by a hydraulic rod. After the shell is cast by the upper and lower molds, the hydraulic rod is activated again, which drives the upper mold to rise until the stop pin contacts the force plate, preventing the connecting plate from rising further. At this time, the spring will tighten, and the top column will slide into the upper mold, pushing the shell out of the upper mold. After the hydraulic rod descends, the top column will return to the initial position under the spring rebound force. Through the above structure, the shell is automatically extruded after casting, avoiding the situation where the shell is stuck in the mold and difficult to remove.

[0019] The cleaning component is set up so that after processing is completed, the motor is started. The motor drives the lead screw to rotate, causing the slider to slide inside the groove. The support frame moves the dust suction port to the center of the lower mold. Then the exhaust fan is started, and the exhaust fan sucks the debris inside the lower mold into the dust suction port. The debris finally enters the collection box through the connecting hose. Through the above structure, the debris in the mold is cleaned after each processing, preventing the accumulation of debris from adversely affecting subsequent processing.
