Abstract
The invention discloses an injection molding mold for mechanical engineering castings, which comprises an upper mold, a lower mold and cavities, wherein an injection runner and a pouring gate are connected to the cavities; the cavities are a first cavity, a second cavity communicated with the first cavity and a third cavity; the cross section of the first cavity is trapezoidal; a round hole is formed in the upper surface of the first cavity and corresponds to the right side of the second cavity; the third cavity are two U-shaped grooves; a stop piece is arranged between the U-shaped grooves; and the U-shaped grooves are deeper than the first cavity and the second cavity. The injection molding mold has the advantages that mass production in enterprises can be realized, so as to improve the efficiency; technical requirements on operators are low; the production costs of the enterprises can be reduced; and products are high in precision and low in rejection rate.
Description
Technical field
The present invention relates to a kind of mould, particularly a kind of injecting molding die for the manufacture of the mechanical engineering foundry goods.
Background technology
The traditional diamond-making technique of component of machine: forging/turning-heat treatment, the parts quality that this processing method is produced depends on staff's technical merit height, therefore, enterprise is very high to staff's technical merit, this has increased the difficulty of recruiting the employee to enterprise, also employee's wage can be very high relatively, improved the production cost of enterprise; Also have the production efficiency of this processing method very low, can not produce in enormous quantities, greatly affected the benefit of enterprise.Therefore, present enterprise is all using injecting molding die, and this production technology is simple to operate, low to staff's technical merit requirement, and can produce in enormous quantities.The quality of parts will depend on filling-pressurize-cooling-demoulding four large processing steps, but yet will see the quality of mould die sinking die cavity.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to operate and high efficiency, high-precision mechanical engineering foundry goods injecting molding die.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of mechanical engineering foundry goods injecting molding die, comprise upper die and lower die and die cavity, described die cavity is connected with injection runner and cast gate, and described die cavity comprises the first die cavity, the second die cavity that is communicated with the first die cavity and the 3rd die cavity; The cross section of described the first die cavity is trapezoidal, has circular hole on its upper surface and with respect to the right side of the second die cavity; Described the 3rd die cavity is two " U " type grooves, is provided with block between described " U " type groove, and the degree of depth of " U " type groove is greater than the degree of depth of the first die cavity and the second die cavity.
As preferably, described circular hole has two, and the center of two circular holes is on same axis.
As preferably, described patrix is provided with projection, has the fixing hole in mating connection with projection on the described counterdie.
As preferably, described counterdie is provided with stripper apparatus.
In sum, the present invention has following beneficial effect:
Use die device of the present invention, enterprise can produce in enormous quantities, has improved efficient; Specification requirement to the operative employee is low; Can reduce the production cost of enterprise; The Product Precision of producing is high, and percent defective is low.
Description of drawings
Fig. 1 is the front view of counterdie of the present invention;
Fig. 2 is the front view of patrix of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
Shown in Fig. 1-2, a kind of mechanical engineering foundry goods injecting molding die comprises patrix 1 and counterdie 2; All be provided with die cavity 3 on patrix 1 and the counterdie 2.Die cavity 3 comprises the first die cavity 31, the second die cavity 32 that is communicated with the first die cavity 31 and the 3rd die cavity 33; The cross section of the first die cavity 31 is trapezoidal, has two circular holes 311 on its upper surface and with respect to the right side of the second die cavity 32; The center of two circular holes 311 is on same axis.The 3rd die cavity 33 is two " U " type grooves, is provided with block 10 between " U " type groove, and the degree of depth of " U " type groove is greater than the degree of depth of the first die cavity 31 and the second die cavity 32.The second die cavity 32 is communicated with injection runner 5 and cast gate 6.
Technical process: at first, patrix 1 and counterdie 2 are combined, be connected and fixed by the projection 9 on the patrix 1 and the fixing hole 8 on the counterdie 2, liquid injects die cavity 3 by the nozzle of injection machine through injection runner 5 and cast gate 6 again, through after pressurize-cooling, use the stripper apparatus 7 that is installed on the counterdie 2 to carry out the demoulding.
