Abstract
The utility model discloses an automobile engine cylinder body sand mould with a fully-coated sand hot core. The automobile engine cylinder body sand mould comprises a bottom plate made from the fully-coated sand hot core, a cylinder hole core, a water jacket, a riser, end sockets and exteriors, wherein the end sockets are arranged at the front side and the rear side of the bottom plate; the exteriors are arranged at the left side and the right side of the bottom plate; the cylinder hole core is arranged on the bottom plate; and the contact parts of the exteriors and the cylinder hole core are provided with the riser and the water jacket. The automobile engine cylinder body sand mould has the following benefits: the coated sand hot core is taken as a basis by the whole equipment; by utilization of the characteristics such as high strength, low thermal expansion and good fluidity of the coated sand hot core and through the mutual combination of different parts, sand core deformation and fracture can be effectively avoided, the size of a casting blank is more stable and machining allowance can be reduced; coated sand has the advantages of low gas evolution and good air permeability, therefore the defects such as pores of the manufactured engine cylinder body can be effectively avoided; and the coated sand is excellent in fluidity and the cavity surface of the sand mould is smoother and cleaner, the surface quality of the manufactured engine cylinder body can be enhanced and the defects such as sand holes can be reduced.
Description
Technical field
The utility model relates to technical field of automobile engine, the hot core automobile engine cylinder-body of particularly a kind of full precoated sand sand mold.
Background technology
The housing assembly of automobile engine is the skeleton of engine, and all major parts and the annex of engine is installed, and bears the various load in the motion.Therefore dimensional accuracy and the quality to cylinder body has higher requirements, in the hope of guaranteeing effective cooperation and the service life of engine between each part.But the sand mold of existing manufacturing engine cylinder-body exists, and coefficient of thermal expansion is big, the characteristics of insufficient strength, gas permeability difference; Therefore; Produced engine cylinder-body is easy to distortion and fracture; Also appear at the engine cylinder surface easily and defectives such as pore occur, cause the engine cylinder-body surface quality relatively poor.This is a problem demanding prompt solution.
The utility model content
The goal of the invention of the utility model is: the problem to above-mentioned existence provides a kind of novel automobile engine cylinder-body sand mold.
The technical scheme that the utility model adopts is such: the hot core automobile engine cylinder-body of a kind of full precoated sand sand mold; Comprise the base plate, cylinder hole core, water jacket, rising head, termination and the external form that adopt the hot core of full precoated sand to make; Said termination is arranged at both sides, base plate front and back; Said external form is arranged at the base plate left and right sides, and said cylinder hole core is arranged on the base plate, and said external form and cylinder hole core contact portion are provided with rising head and water jacket.
In sum; Owing to adopted technique scheme; The beneficial effect of the utility model is: entire equipment is the basis with the hot core of precoated sand, utilizes the high strength, low-thermal-expansion rate of the hot core of precoated sand, good characteristics such as flowability, through the mutual combination of different parts; Can effectively avoid core distortion and fracture, the more stable and minimizing allowance of spray size; The precoated sand gas forming amount is low, and good permeability can effectively avoid occurring on the produced engine cylinder-body defectives such as pore; The precoated sand good fluidity, the sand mold cavity surface is brighter and cleaner, can improve the engine cylinder-body surface quality of manufacturing, reduces defectives such as sand holes.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark among the figure: 1 is base plate, and 2 is cylinder hole core, and 3 is water jacket, and 4 is rising head, and 5 is the termination, and 6 is external form.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
As shown in Figure 1; The hot core automobile engine cylinder-body of a kind of full precoated sand sand mold; Comprise the base plate 1, cylinder hole core 2, water jacket 3, rising head 4, termination 5 and the external form 6 that adopt the hot core of full precoated sand to make, said termination 5 is arranged at both sides, base plate 1 front and back, and said external form 6 is arranged at base plate 1 left and right sides; Said cylinder hole core 2 is arranged on the base plate 1, and said external form 6 is provided with rising head 4 and water jacket 3 with cylinder hole core 2 contact portions.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
