Description
Technical Field
The utility model relates to a water pump casting field, in particular to water pump body casting mould.
Background
The water pump is a machine for conveying liquid or pressurizing liquid; the energy-saving device transmits mechanical energy or other external energy of a prime motor to liquid to increase the energy of the liquid, is mainly used for conveying the liquid including water, oil, acid-base liquid, emulsion, suspoemulsion, liquid metal and the like, and can also convey liquid, gas mixture and liquid containing suspended solids; structural parts on the water pump are relatively more, and many parts need be produced through casting, such as the pump body, impeller, pump body etc. all are the sand core casting, and its cost is relatively low.
At present, at the in-process of casting the pump body of water pump, at present, the valve body to the butterfly valve is carrying out the in-process of processing, can adopt the as cast mode to carry out the shaping usually, at the in-process of carrying out the casting, can use the template, the core box, the psammitolite etc. and because the characteristic of valve body structure itself, the centre of valve body is hollow cavity promptly, consequently when forming middle cavity, need set up corresponding psammitolite in the centre of template, and adopt such structure when casting, can be because the refrigerated nonconformity on the inner wall of one side that the valve body is close to middle psammitolite, thereby lead to appearing the phenomenon of shrinkage cavity, and then lead to the product of production to scrap.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a can reduce water pump body casting mould that the scrapped product produced.
In order to solve the technical problem, the utility model adopts the technical scheme that: the utility model provides a water pump body casting mould, its innovation point lies in: comprises that
The pump body cavity is formed by combining the upper template and the lower template;
the outer walls of the upper template and the lower template are also provided with a plurality of first chills which are uniformly distributed along the outer edge of the first shell or the second shell, the inner walls of the upper template and the lower template are also provided with a plurality of second chills which are distributed in the first cavity or the second cavity, and the inner walls of the upper template and the lower template are also provided with mounting grooves for embedding and mounting the second chills;
the top of the upper shaping plate is also provided with a plurality of air outlet rods, a first riser is arranged in the middle of the upper shaping plate, a second riser communicated with the first cavity is additionally arranged at an inlet of the upper shaping plate close to the first cavity, and the second riser is of a hollow cylindrical structure with an opening at the upper end.
Further, still be provided with a locating component on last template and the template down, locating component is: one side that is located the import department of first die cavity on the upper shaping plate has a convex first location shell that makes progress to form the first location chamber that is linked together with first die cavity, the import department that is located the second die cavity on the lower shaping plate has convex second location shell downwards, thereby forms the second location chamber that is linked together with the second die cavity, first location chamber, second location chamber form a location chamber that is linked together with water pump body die cavity after upper shaping plate and lower shaping plate compound die together, the location chamber is the cuboid form, and the length that the one side that the location chamber contacts with water pump body die cavity will be greater than the length that one side that water pump body die cavity contacts with the location chamber.
The utility model has the advantages that: the utility model discloses in, through add on the lateral wall of last template, lower template and inside wall and establish first chill, second chill and chill to eliminate the phenomenon of shrinkage cavity, in addition because the import department of first die cavity is close to the import of whole die cavity, keep away from first chill, second chill promptly, consequently cooperate through adding to establish the second rising head, further elimination shrinkage cavity phenomenon.
The design of the positioning assembly on the upper template and the lower template is matched with the first positioning shell and the second positioning shell, so that a positioning cavity is realized, the positioning limitation on the position of the sand core is conveniently carried out after the sand core is placed into the template, and the situation that the sand core moves left and right in a cavity of a water pump body to influence the quality of the formed water pump body is avoided in the pouring process.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the utility model discloses a water pump body casting mould's last template's schematic diagram.
Fig. 2 is the utility model discloses a schematic diagram of lower template of water pump body casting mould.
Detailed Description
The following examples are presented to enable those skilled in the art to more fully understand the present invention and are not intended to limit the scope of the present invention.
The casting mold for the pump body of the water pump shown in figures 1 and 2 comprises
A pair of upper template 1, lower template 2 that upper and lower distribution direction distributes side by side have an upwards convex first die shell 11 on the side of upper template 1 to form first die cavity, have a downward convex second die shell 21 on the side of lower template 2, thereby form the second die cavity, first die cavity, second die cavity form a water pump body die cavity jointly after upper template 1 and lower template 2 compound die.
A plurality of air outlet rods are further arranged at the top end of the upper mould plate 1, a first riser is arranged in the middle of the upper mould plate 1, a second riser 13 communicated with the first mould cavity is further additionally arranged at the position, close to the inlet of the first mould cavity, of the upper mould plate 1, and the second riser 13 is of a hollow cylindrical structure with an opening at the upper end.
Still be provided with a locating component on last template 1 and lower template 2, locating component is: one side that is located the import department of first die cavity on last template 1 has a convex first location shell 12 that makes progress, thereby form the first location chamber that is linked together with first die cavity, the import department that is located the second die cavity on template 2 has convex second location shell 22 downwards, thereby form the second location chamber that is linked together with the second die cavity, first location chamber after last template 1 and lower template 2 compound die, the second location chamber forms a location chamber that is linked together with water pump body die cavity jointly, the location chamber is the cuboid form, and the length that the one side that the location chamber contacts with water pump body die cavity will be greater than the length that one side that water pump body die cavity contacts with the location chamber.
