[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0024] Example

[0025] like Figure 1 As shown, Figure 1 What is shown is a three-dimensional schematic diagram of a cold core in an embodiment;

[0026] The cold core 10 is made by combining an upper core box and a lower core box. The cold core 10 includes a cavity 11. A seam 12 is formed at a parting surface in the cavity 11. The device scrapes off the seam 12 during the production of the cold core 10 (after curing and mold opening).

[0027] like Figure 2 , Figure 3 As shown, Figure 2 The figure shows a three-dimensional schematic diagram of the cooperation between the lower core box and the scraping assembly in the embodiment. Figure 3 What is shown is a three-dimensional schematic diagram of the seam scraping assembly in the embodiment, Figure 4 What is shown is a schematic diagram of the cold core in the embodiment cooperating with the device;

[0028] The device includes:

[0029] The lower core box, the working end of which is provided with a fixing module 21;

[0030] The seam scraping assembly 30 includes a scraper 31 movably disposed on the fixed module 21;

[0031] The scraper 31 forms a mold together with the fixed module 21 in a stationary state to form the cold core 10;

[0032] The scraper 31 scrapes off the seams of the formed cold core 10 in an active state.

[0033] The scraper 31 that is movably arranged can form a mold together with the fixed module 21 without affecting the forming of the cold core 10, and can also scrape off the seams of the cold core 10 after the cold core 10 is solidified. There is no need to remove the seams of the cold core 10 separately after the cold core is demolded, which greatly improves the production efficiency of the cold core.

[0034] The fixing module 21 includes a protrusion 22 adapted to the cavity 11 of the cold core 10, and the scraper 31 is lifted and arranged at the top of the protrusion 22;

[0035] The protrusion 22 is arranged to correspond to the cavity 11 , and the scraper 31 has the same shape as the top of the protrusion 22 . The scraper 31 moves vertically at the top of the protrusion 22 to scrape the seam 12 of the cold core 10 .

[0036] It should be noted that due to the gap between the scraper 31 and the fixed module 21, another seam will appear on the cold core 10, but the seam will be removed during the process of the cold core 10 being ejected and demolded: that is, after the scraper finishes its action and returns to its position, the seam is scraped off by the scraper 31 when the cold core 10 is ejected.

[0037] The scraping assembly 30 further includes a connecting rod 33, which is movably inserted from the non-working end of the lower core box and extends to the outside through the protrusion 22. The scraper 31 is arranged at one end of the connecting rod 33 extending outside. The end of the connecting rod 33 away from the scraper 31 is driven by an external force to drive the scraper 31 to move in the vertical direction to scrape the seam 12 of the cold core 10.

[0038] The external force is transmitted through the provided connecting rod 33 so that the scraper 31 can move in the vertical direction.

[0039] A plurality of raised portions 22 are provided on a fixed module 21, and a plurality of connecting rods 33 are provided at one end away from the scraper 31 and extending to the outside, and the same connecting plate 32 and a driving member 34 are provided in sequence. The output end of the driving member 34 is connected to the connecting plate 32, and the driving member 34 drives the connecting plate 32, the connecting rod 33 and the scraper 31 to move in the vertical direction.

[0040] Specifically, there are four protrusions 22 on a fixed module 21 and they are distributed circumferentially. The connecting plate 32 serves to install multiple connecting rods 33. The driving member 34 is a cylinder. The output end of the driving member 34 drives the connecting plate 32 to move in the vertical direction, thereby realizing the vertical movement of the scraper 31. The driving member 34 can be installed outside to ensure that its output end can move freely and play a driving role smoothly.

[0041] A plurality of fixing modules 21 are provided on a lower core box, and a plurality of groups of connecting rods 33 and scrapers 31 are provided corresponding to each fixing module 21 .

[0042] Arranging a plurality of fixing modules 21 can produce a plurality of cold cores 10 at the same time, and each cold core 10 is matched with a corresponding scraper 31. Compared with removing the seams 12 of each cold core 10 separately at a later stage, the use of the device can remove the seams 12 of the cold cores 10 of the same production batch at one time, ensuring that the seams 12 are removed accurately, completely and without omission.

[0043] Working principle: After the cold core 10 is solidified and the mold is opened, under the action of the driving member 34, the scraper 31 moves up and down with the connecting rod 33 to automatically remove the seam 12 at the parting surface of the cold core 10. After the seam 12 is removed, the cold core 10 is ejected from the lower core box to complete the production.

[0044] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
