referring to fig. 6 and 7 of the specification, in the present embodiment, the length of the first scraping block 74 is different from the length of the second scraping block 75.
In this embodiment, the end of the scraper 62 extending into the cavity of the shaping mold 4 is pointed.
In this embodiment, the length of the first scraping block 74 is greater than the length of the second scraping block 75, and the length of the first scraping block 74 may also be set to be smaller than the length of the second scraping block 75, so that the contact portions of the first scraping block 74 and the second scraping block 75 with the scraper 62 are not in the same plane, which prevents the first scraping block 74 and the second scraping block 75 from having the same length, and the contact portions of the first scraping block 74 and the second scraping block 75 with the scraper 62 are in the same plane, when the scraper 62 is scraped, a part of tin is scraped and then clamped between the first scraping block 74 and the second scraping block 75, which affects the surface contact condition of the first scraping block 74 and the second scraping block 75 with the scraper 62; in this embodiment, the end of the scraper 62 is set to be pointed, and the pointed end has a smaller contact degree with the molten tin than the flat surface, so that when the scraper 62 is removed from the cavity of the shaping mold 4, the adhesion of the molten tin to the pointed end of the scraper 62 can be reduced, and the solidification of the tin on the scraper 62 can be reduced.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims; the scope of the invention is defined by the appended claims and equivalents thereof.
