Background
The riser refers to a supplemental portion that is added above or to the sides of the casting to avoid defects in the casting. The riser is communicated with the casting mould, the cavity of the riser is a cavity for storing liquid metal, the metal is supplied when the casting is formed, the main function of the riser is feeding, the effects of preventing shrinkage cavity, exhaust and slag collection are also achieved, and the riser with different design functions is different in form, size and opening position.
In production, there is the foundry goods that the size is great, the pressure angle is less, there is the restriction again in the external mold, can't install the large riser and feed, for example, the cylinder body foundry goods size (1184 x 618 x 900 mm) that I's department produced is great, is restricted by sand box size (1500 x 1200 x 900 mm), foundry goods highest position apart from pouring cup 120mm, the pressure angle only has 12.6, the foundry goods that casts out under this kind of circumstances, can form the shrink at foundry goods surface after molten iron cooling shrink. Therefore, the riser is required to be arranged at the highest point of the casting, but because the upper position of the outer die is too small, only the riser with a smaller base can be arranged, the volume of the riser is too small, and the feeding effect is poor.
Disclosure of Invention
In order to solve the problems in the background technology, the utility model provides a mould structure with a large-size technological riser arranged on a cylinder body with a special structure, and the mould structure can be provided with a riser with larger size so as to meet the requirement of compensating an casting.
The technical scheme adopted by the utility model is as follows: the utility model provides a special structure cylinder body sets up mould structure of jumbo size technology rising head, technology rising head sets up on the last external mold of cylinder body, go up the external mold including setting up the model board at the downside, be equipped with the cylinder body model on the model board, the periphery of cylinder body model is equipped with the external model, the highest department structure of cylinder body model is the air compressor machine installation department model, its up end sets up the rising head model, wherein, the position department of air compressor machine installation department model outside and external model upside is provided with the mold insert, the outer peripheral face of mold insert is equipped with the draft angle, the up end of mold insert is not less than the up end of air compressor machine installation department model, the medial surface of mold insert is extended to its fillet of air compressor machine installation department model one side cladding, rising head model width direction extends to the up end of mold insert.
Further, the outer side of the insert is coplanar with the outer side of the outer mold below the insert.
Further, the connection parts between the circumferential direction and the height direction of the riser model and the insert and the air compressor mounting part model are arranged in a step shape.
According to the die structure, the insert is added to the outer side of the air compressor installation part model by changing the shape structure of the upper outer die, so that the area of the upper outer die at the highest point of the cylinder body casting is increased, the riser with larger volume can be arranged, the feeding effect of the riser is greatly improved, and the complete casting can be formed after pouring and cooling.

Detailed Description
For a better understanding of the objects, structures and functions of the present utility model, a mold structure for a cylinder with a special structure provided with a large-sized process riser according to the present utility model will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-4, a mold structure with a large-size technological riser is arranged on a cylinder body with a special structure, the technological riser is arranged on an upper outer mold of the cylinder body, the upper outer mold comprises a mold plate 1 arranged at the bottom side, a cylinder body mold 2 is arranged on the mold plate 1, an outer mold 3 is arranged on the periphery of the cylinder body mold 2, the highest structure of the cylinder body mold 2 is an air compressor installation part mold 21, a riser mold 4 is arranged on the upper end face of the cylinder body mold 2, an insert 5 is arranged at the position of the outer side of the air compressor installation part mold 21 and the upper side of the outer mold 3, a draft angle is arranged on the outer peripheral surface of the insert 5, the upper end face of the insert 5 is not lower than the upper end face of the air compressor installation part mold 21, the inner side face of the insert 5 extends to the air compressor installation part mold 21 to cover a round angle, and the width direction of the riser mold 4 extends to the upper end face of the insert 5.
According to the utility model, by changing the shape structure of the upper outer die, adding the insert 5 and increasing the area of the collapsed position, the collapsed position can be ensured to be provided with a riser which is large enough, so that the casting process for arranging the riser is realized, the feeding effect of the riser is greatly improved, in addition, the sand core is provided with a structure corresponding to the insert 5, the insert 5 is filled, and the casting integrity of the cylinder body casting is not affected.
In this embodiment, the outer side surface of the insert 5 is coplanar with the outer side surface of the outer mold 3 below the insert 5, and the connection between the circumferential direction and the height direction of the riser mold 4 and the insert 5 and the air compressor mounting portion mold 21 is stepped, so that core assembly is facilitated.
