Description
Technical Field
The utility model relates to a die mould technical field especially relates to an avoid lower die structure of product edge deformation.
Background
Rectangular housing product has flat extension muscle structure because the edge, takes place the in-process that breaks away from at cinder ladle and product, because the package tight power in cinder ladle and cinder ladle groove, causes the product edge to warp easily, in order to avoid the appearance of this condition, designs new lower mould structure very necessary.
Disclosure of Invention
The utility model aims to solve the technical problem that a lower die structure of avoiding product edge to warp is provided, have that exhaust effect is good, improve product quality, ensure that the product edge can not be by characteristics such as stretch bending deformation.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an avoid lower mode construction of product edge deformation, includes die holder, lower mould core and rectangle die cavity, die holder up end middle part embedding install down the mold core, lower mould core up end middle part arranged the rectangle die cavity, rectangle die cavity both sides equipartition put one row of lateral part cinder ladle groove of arranging side by side backward in the past, rectangle die cavity rear side arranged one row of rear portion exhaust cinder ladle, die holder up end rear end embedding install the exhaust piece, the exhaust piece through concentrating runner and rear portion exhaust cinder ladle intercommunication, lateral part cinder ladle groove middle part arranged the rectangular channel, lateral part cinder ladle groove is close to and has arranged the thimble hole in the rectangle die cavity one end.
The front end of the lower die core is provided with a spreader cone which is communicated with the front end of the rectangular die cavity through a runner, and the rear end of the runner adopts a structure of four branched runners.
The side slag ladle groove is communicated with the side wall of the lower die core through a shallow groove.
Has the advantages that: the utility model relates to an avoid lower die structure of product edge deformation, its concrete advantage as follows:
(1) the rear exhaust slag ladle and the side slag ladle groove are arranged to ensure that a large amount of gas is exhausted from the rectangular die cavity, so that the product quality is ensured;
(2) the rectangular groove is formed in the slag ladle, so that the slag ladle is prevented from inclining when being ejected out, and the edge of a product is prevented from being influenced by the slag ladle;
(3) and the synchronous parallel ejection of the product and the slag ladle is realized by arranging the thimble holes.
Drawings
Fig. 1 is a top view of the present invention;
fig. 2 is a structural view of the lateral slag ladle groove of the present invention.
The figure is as follows: 1. the mold comprises a lower mold base, 2 parts of a lower mold core, 3 parts of a spreader cone, 4 parts of a flow channel, 5 parts of a lateral slag ladle groove, 6 parts of a shallow groove, 7 parts of a rectangular mold cavity, 8 parts of a rear exhaust slag ladle, 9 parts of an exhaust block, 10 parts of a rectangular groove, 11 parts of a top needle hole.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The utility model discloses an embodiment relates to an avoid lower die structure of product edge deformation, as shown in fig. 1-2, including die holder 1, lower mold core 2 and rectangle die cavity 7, 1 up end middle part embedding of die holder install lower mold core 2, 2 up end middle parts of lower mold core arranged rectangle die cavity 7, 7 both sides equipartition of rectangle die cavity put one row of lateral part cinder ladle groove 5 of arranging side by side backward in the past, 7 rear sides of rectangle die cavity arranged one row of rear portion exhaust cinder ladle 8, 1 up end rear end embedding of die holder install exhaust piece 9, exhaust piece 9 through concentrating runner and rear portion exhaust cinder ladle 8 intercommunication, 5 middle parts of lateral part cinder ladle groove arranged rectangular channel 10, lateral part cinder ladle groove 5 is close to and has arranged thimble hole 11 in 7 one end of rectangle die cavity.
This technical scheme mainly is used for producing rectangle frame formula product, because rectangle frame formula product edge has than thin extension, in the time of the drawing of patterns, easy because the package tight power stretch bending extension of sediment package, thimble hole 11 has been designed among this technical scheme, be used for adopting thimble structure, make the synchronous drawing of patterns of sediment package and product, sediment package slope when avoiding the drawing of patterns simultaneously, rectangular channel 10 has been designed, rectangular channel 10 plays the positioning action, after the sediment package is deviate from completely, the package tight power that just need not consider the sediment package has been done all can.
The front end of the lower die core 2 is provided with a spreader cone 3, the spreader cone 3 is communicated with the front end of a rectangular die cavity 7 through a runner 4, and the rear end of the runner 4 adopts a structure of four branched runners.
The side slag ladle groove 5 is communicated with the side wall of the lower mold core 2 through a shallow groove 6.
The sediment package of ordinary structure, after the sediment package inslot contracts, partly can separate with sediment package groove lateral wall for the tight power of package between the two reduces, during the die sinking, and the sediment package structure is taken out by last mould easily, and in order to solve this problem, rectangular channel 10 among this technical scheme not only plays the positioning action, can increase the tight power of package between sediment package and the sediment package groove, avoids being taken out by last mould and influences product quality.
