Abstract
The utility model relates to an improved injection molding die. An upper die assembly and a lower die assembly are embedded to form a cavity and an exhaust passage; the upper die assembly comprises an upper die plate and an upper die core; the upper die plate and the upper die core are fixed by a bolt; the lower die assembly comprises a lower die plate and a lower die core; the lower die plate and the lower die core are fixed by a bolt; the lower end of a pouring device is embedded in the upper die core; the upper end of the pouring device is fixed on the upper die plate by a bolt; a feeding passage, a water inlet and outlet passage and a cooling water passage are formed inside the pouring device; the water inlet and outlet passage is communicated with the cooling water passage. Therefore the improved injection molding die is convenient and practical, the forming period can be shortened, working efficiency is improved and a defective rate is reduced, so that production cost is reduced.
Description
Technical field
The utility model relates to a kind of modified form injection mold, especially the injection mold through improvement to apparatus for pouring.
Background technology
Injection mold is the critical component of manufacturing plastic product, when entering the feeding-passage of apparatus for pouring of mould through the plastic raw materials of high temperature high pressure process, can produce impact to charging aperture and feeding-passage wall, long-time in process, repeatedly after cast, charging aperture and feeding-passage there will be breakage, if maintain and repair not in time, can improve the defect rate of finished parts, yet 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, while opening mould, plastic raw materials is difficult for disconnecting with the die joint of finished product, need artificial treatment, caused molding cycle lengthening, reduce production efficiency.
Utility model content
The technical problems to be solved in the utility model is: apparatus for pouring is easy to wear is difficult for demolition and maintenance, and after casting complete, the raw material in feeding-passage is excessively slow cool time, affects operating efficiency.
For addressing the above problem, the utility model discloses a kind of modified form injection mold, comprise that patrix is 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 with 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 by metal material.
The beneficial effects of the utility model: 1, reduce production costs; 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 the utility model modified form injection mold.
Fig. 2 is the top view of the apparatus for pouring of the utility model modified form injection mold.
The specific embodiment
By reference to the accompanying drawings specific implementation method of the present utility model is described further.
A kind of modified form injection mold, comprise that patrix is 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 ends are embedded in upper cores 2, apparatus for pouring 8 upper ends are bolted on cope match-plate pattern 1, apparatus for pouring 8 inside are 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 with tapering, the axis coinciding of the shaft core position of feeding-passage 9 and apparatus for pouring 8.
Apparatus for pouring 8 is made by 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, counterdie overall and apparatus for pouring 8, 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 ends are embedded in upper cores 2, and apparatus for pouring 8 upper ends are bolted on cope match-plate pattern 1, overall and the counterdie of patrix is totally by inlaying, formation die cavity 6 and exhaust passage 11.
As preferably, apparatus for pouring 8 is made by 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 being located at the sprue gate 5 in upper cores 2, enters formed die cavity 6.
As preferably, feeding-passage 9 is with tapering, the center superposition of the center of feeding-passage 9 and apparatus for pouring 8.
Cooling:
To turnover water channel 10 cooling waters on apparatus for pouring 8, afterwards, cooling water enters the cooling duct 7 in apparatus for pouring 8, carry out exchange heat 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 end, can manually pour out all the other cooling waters.
It is evident that above description and to record be only for example rather than in order to limit disclosure of the present utility model, application or use.Although described in an embodiment and be described in the drawings embodiment, but the optimal mode that the utility model does not limit by accompanying drawing example and the conduct of describing is in an embodiment thought to be at present to implement the specific examples of instruction of the present utility model, scope of the present utility model will comprise any embodiment of the description that falls into above and appended claim.
