Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical casting, and in particular relates to a device for increasing the sand-shooting capacity. Background Technology
[0002] In the field of automotive parts casting, sand casting is widely used. (e.g., for automotive parts...)
[0003] The production and manufacturing of automotive turbochargers, etc. Automotive parts, specifically turbocharger sand casting, involves pouring high-temperature molten steel into the cavity of a pre-shaped turbocharger sand mold. After the mold cavity cools, a blank of the corresponding automotive part is obtained. However, during the production process, some turbocharger housing sand molds are large and heavier than the equipment's injection sand storage capacity, making single-shot sand casting insufficient. During production, a second sand injection is required to complete the turbocharger sand mold forming. A single-shot turbocharger sand mold forming can be completed in (140 seconds), while a second-shot forming requires at least (190 seconds).
[0004] In the sand casting production process of automotive turbochargers, if a single sand shot fails to form the desired shape, a second sand shot is typically used to compensate for the unformed sand mold. The disadvantages of this method are as follows:
[0005] 1. Low work efficiency, wasting human and material resources;
[0006] 2. The equipment suffers significant wear and tear. Utility Model Content
[0007] The purpose of this utility model is to provide a device for increasing sand injection capacity, so as to solve the technical problem of low work efficiency and high equipment wear caused by the need for secondary sand injection to supplement the sand mold forming of the turbocharger shell of automotive parts due to the large sand mold.
[0008] To achieve the above objectives, the specific technical solution of the present invention for increasing the sand-shooting capacity is as follows:
[0009] A device for increasing sand-shooting capacity includes: a sand-shooting plate and a sand-storing iron frame; wherein the sand-shooting plate is located at the bottom of the sand-storing iron frame; the four sides are sand-storing iron frames higher than the sand-shooting plate; several screws are fixed to the drilled holes of the sand-shooting plate in the cold core box; positioning pins are locked on the screws to lock the screws to the sand-storing iron frame.
[0010] Furthermore, the sand-shooting plate is a metal structure plate made of rectangular iron plate, steel plate, or stainless steel plate; the outer rectangular plate has a length × width of 1250mm × 1100mm; the inner rectangular plate has a length × width of 1150mm × 900mm, the distance from the inner length to the edge is 100mm, the distance from the inner width to the edge is 50mm, and the thickness of the iron plate is 40mm; the rectangular plate has several holes arranged longitudinally and laterally, with six rows longitudinally and six rows laterally in two groups, each group having four rows in the middle of the longitudinal and transverse directions, for a total of 24 holes, with six holes in each row; there is one row at each end, with four holes in each row, for a total of 8 holes, evenly arranged at both ends of the plate body with the transverse center as the dividing line.
[0011] Furthermore, the distance with the center line in the horizontal direction as the dividing line is 1150mm / 2.
[0012] Furthermore, the height of the sand storage iron frame is 40mm.
[0013] Furthermore, several positioning posts are installed on the sand storage iron frame, which are connected to the inside of the screws to position the core box and the equipment.
[0014] The device for increasing shot blasting capacity of this invention has the following advantages:
[0015] This invention has a simple structure, which not only solves the problem of secondary sand-shooting in the equipment and improves production efficiency, but also reduces the input of manpower and material resources and the problem of large equipment wear and tear. Attached Figure Description
