Description

Technical Field

[0001] This utility model relates to the field of core shooting machine technology, and in particular to a core shooting machine. Background Technology

[0002] Core shooting machines for casting production are widely used in the casting industry. Their working principle is to inject a core sand mixture with liquid or solid thermosetting resin as a binder into a heated core box. The sand core is preheated in the core box and quickly hardens to a certain thickness before being removed, forming a high-quality sand core product with a smooth surface and accurate dimensions. The injection molding machine for casting production uses compressed air to evenly inject molding sand into the sand box for pre-compacting, and then applies pressure for compaction.

[0003] After the casting is formed, the upper and lower molds on the core shooting machine separate. The formed casting is located in the casting cavity of the lower mold. Since the casting cavity of the lower mold is a concave groove, and the casting is embedded in the groove, the workers need to spend time to remove the formed casting from the groove before production can continue, which affects the production efficiency and is quite inconvenient.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] This utility model provides, for example Figure 1-2The illustrated core shooting machine includes a worktable 1, a core shooting machine body 3, a drive mechanism 4, an upper mold 5, a positioning and ejection mechanism 6, and a lower mold 7. A mounting frame 2 is fixedly connected to the top of the worktable 1. The core shooting machine body 3 is fixedly mounted on the top of the mounting frame 2. The drive mechanism 4 is mounted on the mounting frame 2 and connected to the upper mold 5. The positioning and ejection mechanism 6 is mounted on the worktable 1 and has a lower mold 7. The upper mold 5 and the lower mold 7 cooperate with each other. By setting two lower molds 7 that cooperate with the upper mold 5 on the positioning and ejection mechanism 6, after the casting is formed by one lower mold 7 and the upper mold 5, the positioning and ejection mechanism 6 can quickly switch to the other lower mold 7 to continue production while simultaneously ejecting the formed casting. This improves production efficiency, avoids downtime caused by removing the casting, and makes the production process more continuous and stable, making it easy to use.

[0036] The drive mechanism 4 includes cylinders 41 and mounting plates 42. Cylinders 41 are symmetrically fixedly mounted on the top of the mounting frame 2, and the output ends of cylinders 41 are all connected to the mounting plates 42 for transmission. The upper mold 5 is fixedly mounted on the bottom of the mounting plate 42. The cylinders 41 can drive the upper mold 5 on the mounting plate 42 to move vertically, facilitating cooperation or separation with different lower molds 7. When casting is required, the cylinders 41 push the mounting plate 42 and the upper mold 5 downward to fit tightly with the corresponding lower mold 7, starting the casting process. After the casting of a part is completed, the cylinders 41 drive the mounting plate 42 and the upper mold 5 upward to disengage from the lower mold 7, leaving space for switching to the next lower mold 7 or performing other operations.

[0037] Example 2

[0038] Based on Example 1, such as Figure 3As shown, the positioning and ejection mechanism 6 includes a slider 61, a positioning plate 62, an ejection plate 63, an ejection rod 64, a fixing rod 65, a compression spring 66, a snap-fit ​​plate 67, a limit block 68, a gear 69, and a rack 610. A groove is provided at the top of the worktable 1, and the slider 61 is slidably inserted into the inner cavity of the groove. The lower mold 7 is symmetrically fixedly connected to the top of the slider 61. The positioning plate 62 is fixedly connected to both sides of the worktable 1, and its cross-section is C-shaped. The ejection plate 63 is slidably disposed inside the lower mold 7. An adjustment groove is provided inside the slider 61. One end of the ejection rod 64 is slidably inserted into the inner cavity of the adjustment groove, and the other end of the ejection rod 64 passes through the lower mold 7 and is fixedly connected to the ejection plate 63. One end of the fixing rod 65 is fixedly connected to the inner cavity of the adjustment groove. The wall is fixedly connected, and the other end of the fixed rod 65 is slidably inserted into the inner cavity of the ejector rod 64. The compression spring 66 is sleeved on the outside of the fixed rod 65, one end of the compression spring 66 is fixedly connected to the ejector rod 64, and the other end of the compression spring 66 is fixedly connected to the inner wall of the adjustment groove. The snap-fit ​​plate 67 is slidably disposed inside the adjustment groove, and the snap-fit ​​plate 67 is slidably inserted into the inner cavity of the positioning plate 62. The limiting block 68 is fixedly connected to the outer wall of the snap-fit ​​plate 67. A limiting groove is opened on one side of the inner wall of the adjustment groove, and the limiting block 68 is slidably inserted into the inner cavity of the limiting groove. The gear 69 is rotatably disposed inside the adjustment groove through a rotating shaft. The rack 610 is equidistantly fixedly connected to the side of the ejector rod 64 opposite to the snap-fit ​​plate 67, and the rack 610 is meshed with the gear 69. After the lower mold 7, located below the upper mold 5, completes the forming of the casting, the ejector plate 63 inside the other lower mold 7 can be pressed, causing the ejector rod 64 to slide downwards. This, in turn, drives the gear 69 to rotate via the rack 610, causing the locking plate 67 to retract into the slider 61 under the limit of the limiting block 68. At this time, the lower mold 7 can be switched by sliding the slider 61 normally. Simultaneously, when the lower mold 7 forming the casting contacts the inner wall of the other positioning plate 62, the elastic force of the compression spring 66 will eject the casting, causing the locking plate 67 to engage with the inner cavity of the positioning plate 62, thereby achieving positioning. This improves production efficiency, avoids downtime caused by removing the casting, and makes the production process more continuous and stable, making it easier to use.

[0039] Furthermore, the bottom end of the snap-fit ​​plate 67 is provided with a groove, and a roller 611 is rotatably installed inside the groove to fit against the inner wall of the slide. The roller 611 prevents the snap-fit ​​plate 67 from directly fitting against the inner wall of the slide, thus extending the service life of the snap-fit ​​plate 67.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
