Description
The application is divisional application, the invention and created name of original application: a kind of agricultural machinery foundry goods injecting molding die, application number: 201210479786.0, the applying date: 2012-11-23.
Technical field
The present invention relates to a kind of mould, particularly a kind of injecting molding die for the manufacture of agricultural machinery 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 the technical merit height of staff, therefore, enterprise is very high to the technical merit of staff, this adds the difficulty of recruiting employee to enterprise, also the wage of employee can be very high relatively, improves the production cost of enterprise; Also have the production efficiency of this processing method very low, can not produce in enormous quantities, greatly have impact on the benefit of enterprise.Therefore, present enterprise is all using injecting molding die, this production technology, simple to operate, low to the technical merit requirement of staff, and can produce in enormous quantities.The quality of parts will depend on the large processing step of filling-pressurize-cooling-demoulding four, but yet will see the quality of mould die sinking die cavity.
Summary of the invention
The object of this invention is to provide a kind of structure simple, easy to operate and high efficiency, high-precision agricultural machinery foundry goods injecting molding die.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of agricultural machinery 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, described die cavity comprises the first die cavity and the second die cavity, between the first die cavity and the second die cavity, be provided with bumping post, described bumping post is the reeded cylinder of band; Cross central line along them in the first die cavity and the second die cavity is respectively provided with horizontal block; The end of the block of described first die cavity and the second die cavity respectively has " recessed " type groove; On the surface of patrix and counterdie, the longitudinal centre line along the first die cavity and the second die cavity respectively has " u " type groove, is provided with guide rod in described " u " type groove.
As preferably, the degree of depth of described " recessed " type groove is less than the degree of depth of the first die cavity and the second die cavity.
As preferably, described patrix is provided with projection, and described counterdie has the fixing hole in mating connection with projection, and described counterdie is provided with stripper apparatus.
The method of work of above-mentioned agricultural machinery foundry goods injecting molding die, it comprises: liquid injects mold cavity through injection runner and cast gate, after pressurize, cooling, by being arranged on the stripper apparatus demoulding of counterdie by the nozzle of injection machine.
In sum, the present invention has following beneficial effect: use die device of the present invention, enterprise can produce in enormous quantities, improves efficiency; Low to the technical requirement of operative employee; The production cost of enterprise can be reduced; The Product Precision produced is high, and percent defective is low.
Accompanying drawing explanation
Fig. 1 is the front view of counterdie of the present invention;
Fig. 2 is the front view of patrix of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1-2, a kind of agricultural machinery foundry goods injecting molding die, comprises patrix 1 and counterdie 2.Patrix 1 and the surface of counterdie 2 are respectively equipped with protruding 9 and fixing hole 8, and projection 9 and fixing hole 8 cooperatively interact and are connected and fixed.The die cavity 3 of injecting molding die comprises the first die cavity 31 and the second die cavity 32, between the first die cavity 31 and the second die cavity 32, be provided with bumping post 4, and bumping post 4 is cylinders of a band fluted 41.In the first die cavity 31 and the second die cavity 32, the direction along the cross central line of the first die cavity 31 and the second die cavity 32 is respectively provided with one piece of horizontal block 10; " recessed " type groove 7 is respectively had in the end of block 10.The degree of depth of " recessed " type groove (7) is less than the degree of depth of the first die cavity (31) and the second die cavity (32).At patrix 1 with on the surface of counterdie 2, the longitudinal centre line along the first die cavity 31 and the second die cavity 32 respectively has " u " type groove 12, is provided with guide rod 13 in described " u " type groove 12.
In addition, die cavity 3 is communicated with injection runner 5 and cast gate 6, workflow: liquid injects mold cavity 3 by the nozzle of injection machine through injection runner 13 and cast gate 14, after pressurize, cooling, by being arranged on stripper apparatus 11 demoulding of counterdie 2.
