Description

Technical Field

[0001] The utility model belongs to the field of automobile parts production molds, in particular to a horizontal production line mold for automobile parts production. Background Art

[0002] Auto parts such as pump parts are produced by sand casting. Sand casting is the most widely used casting method in casting production. Sand is used as the main molding material. The sand is compacted to form a casting cavity. After the molten metal is poured and solidified, the sand mold is removed to take out the casting.

[0003] The traditional molding process is complicated and mostly done manually, that is, first place a base plate on the molding station, place a mold plate on the base plate, place a sand box outside the mold plate, inject molding sand into the sand box and compact it, and take out the mold plate. Since the mold plate has the shape of the molded part, the final sand box includes the corresponding cavity, and pouring can be completed by injecting liquid metal into the cavity. However, this molding process has high technical requirements and high labor intensity.

[0004] By changing the traditional manual modeling to the horizontal production line process, a large number of molds suitable for the production line are needed. The number of molds that can be molded at one time is usually one. Therefore, if a set of symmetrical castings is produced, the number of molds used will double, which is not conducive to controlling costs and improving production efficiency. Utility Model Content

There are two pump shell molds and the two are symmetrically arranged on the left and right. A pair of casting process packages are arranged on both sides of each pump shell mold, and fire sealing grooves are arranged around the pump shell mold and the casting process package. A channel mold package spanning the casting process packages corresponding to different pump shell molds is arranged at the bottom of the template, and a riser corresponding to the channel mold package is arranged on the top of the template. The riser is hemispherical, and exhaust holes are arranged on the casting process package and the riser.

[0007] Preferably, the side surface of the template is provided with blind holes distributed along the circumference direction thereof, and the blind holes are distributed close to the top surface of the template.

[0008] Preferably, the two pump shell parts are connected integrally.

[0009] Preferably, a character mold is provided on the pump shell mold.

[0010] Preferably, the pump shell mold is provided with a plurality of symmetrically distributed bolt connection mold holes.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Examples, such as Figures 1 to 4 As shown, the utility model provides a horizontal production line mold for automobile parts production, including a rectangular mold plate 1, a pump shell mold 2 is arranged on the mold plate 1, and mounting holes 3 are arranged at the corners of the mold plate 1. There are two pump shell molds 2 and the two are symmetrically arranged on the left and right. A pair of casting process packages 4 are arranged on both sides of each of the pump shell molds 2, and fire sealing groove-shaped convexities 5 are arranged around the pump shell mold 2 and the casting process package 4. A channel-shaped package 6 spanning the casting process packages 4 corresponding to different pump shell molds 2 is arranged at the bottom of the mold plate 1. The channel-shaped package 6 is a dumbbell-shaped structure, and its two ends correspond to two different casting process packages 4 respectively. A riser 7 corresponding to the channel-shaped package 6 is arranged on the top of the mold plate 1, and the riser 7 is a hemispherical surface. Exhaust holes 8 are arranged on the casting process package 4 and the riser 7. The exhaust holes 8 can ensure the smoothness of the molding surface and reduce the situation of local convex adhesion of the molding sand. At the same time, the production of the sand shell is also beneficial to improving the surface quality of the subsequent casting products.

[0023] Specifically, the mold can simultaneously create two symmetrical surfaces in the sand box. The symmetrical design of the pump shell mold 2 is conducive to balanced force and ensures the quality of the molding. The sand shell produced by the mold provides a relatively continuous channel for the pouring process, has a symmetrical pouring process package for forming a pouring inlet, and a reasonable riser 7 structure is arranged to reduce the number of shrinkage and pores in the casting. The fire-sealing groove convex 5 is used to ensure the uniformity and sealing of the poured metal liquid, which is beneficial to improving the quality of the casting, controlling costs and improving production efficiency.

[0024] In order to improve the utilization rate of the mold plate 1, the utility model is provided with blind holes 9 distributed along the circumference direction of the mold plate 1 on the side surface of the mold plate 1, and the blind holes 9 are distributed near the top surface of the mold plate 1. The blind holes 9 can be used as tool nodes for lifting the mold plate 1 from the sand box, and can be used as installation nodes for scraping strips. After the scraping strips are installed, they can be separated when the sand box is parted, and the sand on the parting surface is swept away by the scraping strips, which is beneficial to improve the quality of the castings formed by the subsequent pouring of the mold cavity.

[0025] In order to improve the pouring efficiency, the two pump shell molds 2 provided by the utility model are connected as one body, and the sand shells thereof are also integrated, so the pouring cavity is also connected, and the connecting function of the channel mold package 6 at the bottom of the two is beneficial to improve the pouring efficiency and pouring quality.

[0026] Furthermore, the utility model provides a mold on the pump shell mold 2 for forming a sand shell with the mold, and then pouring a casting with a code.

[0027] In order to improve product production efficiency, the utility model directly arranges a plurality of symmetrically distributed bolt connection mold holes 10 on the pump casing mold part 2, so that the final cast product is directly provided with holes after being formed, and only needs fine turning and fine drilling before leaving the factory, thus reducing the rough turning and rough drilling processes.

[0028] In order to improve the pouring quality, the edge of the fire-sealing groove convex 5 provided by the utility model is inclined to transition with the plate surface of the mold plate 1. In this way, the edge of the fire-sealing groove of the sand shell is narrowed, and the cast metal liquid can form an effective sealing structure in the fire-sealing groove, which is beneficial to reduce the probability of pores in the casting and ensure the integrity of the shape of the casting.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
