Abstract
The utility model discloses a die for precisely casting a combustion chamber insert block of an internal combustion engine. The die comprises a first die part and a second die part, wherein the first die part and the second die part are matched to form a die cavity; the die also comprises a third die part; the third die part is movably arranged in the first die part; one end of the third die part extends out of a first die core; the first die core enters the die cavity along with a matched through hole which is formed in the first die part; an elastic part is also arranged between the third die part and the first die part; the die also comprises a fastening part; the fastening part is used for pressing the third die part in the first die part. After casting, the fastening part can be unlocked and the third dir part is stably popped out in the presence of the elastic part at the moment, thus stably drawing the first die core out of a wax part die, avoiding the deformation of the wax part die when manually opening the die and guaranteeing the precision of the wax part die.
Description
Technical field
The utility model relates to field of metal casting technology, is specifically related to a kind of Combustion Chamber Insert In Internal Combustion Engine precision casting mold.
Background technology
In engineering, have a lot of foundry goods to need hot investment casting, the casting method generally using at present, normally obtains foundry goods from Mold Making, wax-pattern processed, shell processed, roasting, casting metal.But for the extra high foundry goods of precision requirement, due to the restriction of the self structure of foundry goods, at wax-pattern processed and dewaxing mould be, easily cause the certain distortion of wax-pattern, affect the quality of foundry goods.
Especially for Combustion Chamber Insert In Internal Combustion Engine, Combustion Chamber Insert In Internal Combustion Engine is a part that requirement is very accurate, and particularly plot ratio requires very highly, and error requirements≤0.1%, otherwise affect the mixed proportion of combustion gas and air, affects combustion efficiency.In Combustion Chamber Insert In Internal Combustion Engine mould, there is oblique through hole, original precision casting mold structural design is simple, artificial die sinking is extracted workpiece from through hole, oblique extracting by it, in this process, very easily cause the distortion to a certain degree of wax part, cause wax part dimensional accuracy low, be difficult to ensure product size precision.
Therefore, need a kind of novel mould structure, automatic die sinking, automatic flexible depoling, can ensure dimensional accuracy and the uniformity of wax part, and can meet large batch of Production requirement, meets the technical requirement of product to plot ratio completely.
Summary of the invention
The utility model provides a kind of Combustion Chamber Insert In Internal Combustion Engine precision casting mold, automatic die sinking, and automatic flexible depoling, has ensured dimensional accuracy and the uniformity of wax part.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical proposals: Combustion Chamber Insert In Internal Combustion Engine precision casting mold, comprise the first mold members, the second mold members, after coordinating with the second mold members, described the first mold members forms mold cavity, it is characterized in that, also comprise the 3rd mold members, described the 3rd mold members is movably set in described the first mold members, the first mold core is extended in described the 3rd mold members one end, the through hole that described the first mold core can prolong the coupling of being located at described the first mold members enters in mold cavity, between described the 3rd mold members and described the first mold members, be provided with elastic component, also comprise described the 3rd mold members is pressed on to the securing member in described the first mold members.After having cast, can untie described securing member, now described the 3rd mold members is ejected stably under elastic component effect, and the first mold core is extracted out stably from wax part mould, the distortion of having avoided artificial die sinking to cause wax part mould, has ensured the precision of wax part mould.
As preferably, described elastic component is spring.When die sinking, rely on the elasticity of spring that the first mold core is extracted out stably from wax part mould.
As preferably, described securing member is the first fastening assembly being connected with described the first mold members and the second fastening assembly being connected with described the first fastening assembly or described the first mold members.Connected mode can be for being spirally connected or other dismountable connections, when the first fastening assembly is fixed in the first mold members, after the second fastening assembly is fixed in the first fastening assembly or the first mold members, described the 3rd mold members can be pressed in described the first mold members, now the first mold core enters in mold cavity through the through hole mating with it in the first mold members, and spring is compressed simultaneously.When die sinking, take off the first fastening assembly and the second fastening assembly, described the 3rd mold members is ejected stably under spring action, and the first mold core is extracted out stably from wax part mould.
As preferably, described the second mold members is provided with the second mold core.Described the second mold core participates in forming described mold cavity, when die sinking, can, by taking off the second mold core, take out easily wax part mould, and the distortion of simultaneously having avoided artificial delivery to cause wax part mould has ensured the precision of wax part mould.
As preferably, oblique the stretching in mold cavity of described the first mold core.In Combustion Chamber Insert In Internal Combustion Engine mould, have oblique through hole, when artificial die sinking, more easily cause the distortion to a certain degree of wax part, automatic die sinking can ensure the precision of product.
Compared with prior art, the utlity model has following beneficial effect:
The utility model automatic die sinking, the distortion of having avoided artificial die sinking to cause wax part mould, has ensured the precision of wax part mould.
Automatic mould-opening device of the present utility model is simple in structure, and changing traditional cylinder die sinking is that elastic component ejects die sinking, has saved equipment cost, and die sinking is effective.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail: Combustion Chamber Insert In Internal Combustion Engine precision casting mold, comprise the first mold members 2, the second mold members 6, after coordinating with the second mold members 6, described the first mold members 2 forms mold cavity 7, also comprise the 3rd mold members 4, described the 3rd mold members 4 is movably set in described the first mold members 2, the first mold core 41 is extended in described the 3rd mold members 4 one end, the through hole that described the first mold core 41 can prolong the coupling of being located at described the first mold members 2 enters in mold cavity 7, between described the 3rd mold members 4 and described the first mold members 2, be provided with elastic component, also comprise described the 3rd mold members 4 is pressed on to the securing member in described the first mold members 2.In present embodiment, described elastic component is spring 5.In present embodiment, described securing member is the first fastening assembly 1 being connected with described the first mold members 2 and the second fastening assembly 3 being connected with described the first fastening assembly 1, certain the second fastening assembly 3 also can be connected to described the first mold members 2, and connected mode can be for being spirally connected or other dismountable connections.
