Abstract

The utility model discloses a cylinder body jacket core cold box die blast nozzle which comprises a blast nozzle body (2) fixedly arranged on a blast plate (1), wherein the cross section of the internal hole (4) of the blast nozzle main body (2) is of an oval shape; and a blast nozzle sealing ring (3) is connected to the lower end of the blast nozzle main body (2). The cylinder body jacket core cold box die blast nozzle t is high in rate of core-making finished products and high in production efficiency.

Description

Cylinder body water jacket core cold-box mould is penetrated Sha Zui

Technical field

The utility model relates to automobile engine cylinder-body jacket core cold-box technical field of mold, specifically is that a kind of cylinder body water jacket core cold-box mould is penetrated Sha Zui.

Background technology

At present, the cylinder body water jacket core of automobile engine is narrow sand wall product, and the sand mouth of penetrating of four cylinders of the automobile engine of prior art, six cylinder cylinder body water jacket core cold-box moulds is that circle is penetrated Sha Zui; In the process of system cylinder body water jacket core; Since circular penetrate the sand mouth penetrate the little and solid gas triethylamine of sand area to advance the amine area little, so the cylinder body water jacket core that causes making is not full, triethylamine solidifies imperfect; In large batch of coremaking process; The core yield rate is lower, and the while die debugging is more complicated also, and production efficiency is low.

The utility model content

The technical problem that the utility model will solve is, overcomes the defective of above prior art, provide a kind of coremaking yield rate high, and the high cylinder body water jacket core cold-box mould of production efficiency penetrated Sha Zui.

The technical solution of the utility model is; Provide a kind of cylinder body water jacket core cold-box mould with following structure to penetrate Sha Zui: it comprises being fixedly mounted on to penetrate penetrates sand mouth body on the sand plate; The described endoporus cross section of penetrating sand mouth body is for oval, and the lower end of penetrating sand mouth body is connected with and penetrates sand mouth sealing ring.

After adopting above structure, the utility model cylinder body water jacket core cold-box mould is penetrated the sand mouth compared with prior art, has the following advantages: this cylinder body water jacket core cold-box mould is penetrated the endoporus cross section of sand mouth for oval; This ellipse is penetrated the sand mouth and has been increased and penetrate the sand area and advance the amine area; Therefore the cylinder body water jacket core of making is full, and it is complete that triethylamine is solidified, and the yield rate of coremaking is high; And prolonged cleaning, the life cycle of mould, improved production efficiency.

As preferably, the described sand mouth body of penetrating is penetrated sand mouth body for what process with the H13 steel, so its long service life, and is durable.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4,

The utility model cylinder body water jacket core cold-box mould is penetrated Sha Zui, and it comprises being fixedly mounted on to penetrate penetrates sand mouth body 2 on the sand plate 1, and described endoporus 4 cross sections of penetrating sand mouth body 2 are for oval, and the lower end of penetrating sand mouth body 2 is connected with and penetrates sand mouth sealing ring 3.

The described sand mouth body 2 penetrated is penetrated sand mouth body for what process with the H13 steel.

Claims

1. a cylinder body water jacket core cold-box mould is penetrated Sha Zui; It comprises being fixedly mounted on to penetrate penetrates sand mouth body (2) on the sand plate (1); It is characterized in that: described endoporus (4) cross section of penetrating sand mouth body (2) is for oval, and the lower end of penetrating sand mouth body (2) is connected with and penetrates sand mouth sealing ring (3).
