Abstract
The invention relates to an improved injection mold. An upper mold main body and a lower mold main body are inlaid with each other to form a cavity and an exhausting channel, wherein the upper mold main body comprises an upper mold plate and an upper mold core, which are fixed by a bolt, the lower mold main body comprises a lower mold plate and a lower mold core, which are fixed by a bolt, the lower end of a pouring device is inlaid in the upper mold core, the upper end of the pouring device is fixed on the upper mold plate by a bolt, a feeding channel, a water inlet and outlet channel and a cooling water channel are arranged inside the pouring device, and the water inlet and outlet channel is communicated with the cooling water channel. The improved injection mold is convenient and practical, the molding period can be shortened, the working efficiency is improved, the defective rate is reduced and the production cost is further reduced.
Description
Technical field
The present invention relates to a kind of modified form injection mold, especially to the injection mold of apparatus for pouring through improvement.
Background technology
Injection mold is the critical component manufacturing plastic product, when the plastic raw materials through high temperature high pressure process enters the feeding-passage of the apparatus for pouring of mould, can produce charging aperture and feeding-passage wall and impact, passing through for a long time, repeatedly after cast, charging aperture and feeding-passage there will be breakage, if maintain and repair not in time, the defect rate of finished parts can be improved, but traditional injection mold, apparatus for pouring and whole mould are integrated, be not easy to detachable maintaining, take time and effort, and, traditional moulds is after injection moulding completes, when opening mould, plastic raw materials not easily disconnects with the die joint of finished product, need artificial treatment, result in molding cycle to lengthen, reduce production efficiency.
Summary of the invention
The technical problem to be solved in the present invention is: apparatus for pouring not easily demolition and maintenance easy to wear, and after casting complete, the raw material in feeding-passage is excessively slow for cool time, affects operating efficiency.
For solving the problem, the invention discloses a kind of modified form injection mold, comprise patrix overall, overall and the apparatus for pouring of counterdie, overall and the described counterdie of described patrix is totally by inlaying, form die cavity and exhaust passage, patrix totally comprises cope match-plate pattern and upper cores, both are bolted, counterdie totally comprises lower bolster and lower die, both are bolted, apparatus for pouring lower end is embedded in upper cores, apparatus for pouring upper end is bolted on cope match-plate pattern, apparatus for pouring inside is provided with feeding-passage, turnover water channel and cooling water channel, turnover water channel is connected with cooling water channel, upper cores is provided with sprue gate, the one end at sprue gate is connected with feeding-passage, the other end at sprue gate is connected with die cavity, feeding-passage is band tapering, the shaft core position of feeding-passage and the axis coinciding of apparatus for pouring.
As preferably, the width of cooling water channel is 5mm-20mm.
As preferably, described apparatus for pouring is made up of metal material.
Beneficial effect of the present invention: 1, reduce production cost; 2, shorten molding cycle, enhance productivity, reduction in the numbers of seconds, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of modified form injection mold of the present invention.
Fig. 2 is the top view of the apparatus for pouring of modified form injection mold of the present invention.
Detailed description of the invention
By reference to the accompanying drawings specific embodiment of the invention method is described further.
A kind of modified form injection mold, comprise patrix overall, overall and the apparatus for pouring 8 of counterdie, overall and the described counterdie of described patrix is totally by inlaying, form die cavity 6 and exhaust passage 11, patrix totally comprises cope match-plate pattern 1 and upper cores 2, both are bolted, counterdie totally comprises lower bolster 4 and lower die 3, both are bolted, apparatus for pouring 8 lower end is embedded in upper cores 2, apparatus for pouring 8 upper end is bolted on cope match-plate pattern 1, apparatus for pouring 8 inside is provided with feeding-passage 9, turnover water channel 10 and cooling water channel 7, turnover water channel is connected with cooling water channel 7, upper cores 2 is provided with sprue gate 5, the one end at sprue gate 5 is connected with feeding-passage 9, the other end at sprue gate 5 is connected with die cavity 6, feeding-passage 9 is band taperings, the shaft core position of feeding-passage 9 and the axis coinciding of apparatus for pouring 8.
Apparatus for pouring 8 is made up of metal material.
The width of cooling water channel 7 is 5mm-20mm.
Matched moulds:
As depicted in figs. 1 and 2, modified form injection mold, comprise that patrix is overall, the overall and apparatus for pouring 8 of counterdie, described patrix totally comprises cope match-plate pattern 1 and upper cores 2, and both are bolted, described counterdie totally comprises lower bolster 4 and lower die 3, both are bolted, and described apparatus for pouring 8 lower end is embedded in upper cores 2, and apparatus for pouring 8 upper end is bolted on cope match-plate pattern 1, overall and the counterdie of patrix totally by inlaying, formation die cavity 6 and exhaust passage 11.
As preferably, apparatus for pouring 8 is made up of metal material.
Injection molding:
As depicted in figs. 1 and 2, plastic raw materials, via the nozzle of injection machine, enters the feeding-passage 9 in apparatus for pouring 8, then through the sprue gate 5 be located in upper cores 2, enters formed die cavity 6.
As preferably, feeding-passage 9 is band tapering, the center of feeding-passage 9 and center superpositions of apparatus for pouring 8.
Cooling:
To turnover water channel 10 cooling water of on apparatus for pouring 8, afterwards, cooling water enters the cooling duct 7 in apparatus for pouring 8, exchange heat is carried out with feeding-passage 9, when water level rises to the height of turnover water channel 10 of the other end, unnecessary cooling water can flow out, and takes away heat, after cooling terminates, can manually pour out all the other cooling waters.
It is evident that, above description and record be only citing instead of in order to limit disclosure of the present invention, application or use.Although described in an embodiment and be described in the drawings embodiment, but the present invention do not limit by accompanying drawing example and describe in an embodiment as the optimal mode thought at present to implement the specific examples of instruction of the present invention, scope of the present invention will comprise any embodiment of description and the appended claim fallen into above.
