Description
Technical field
The utility model relates to the injection mold field, relates in particular to the injection core cooling device.
Background technology
In the production process of plastic products, need utilize mold injection molding, in the process of mold injection molding; Cooling becomes an extremely important link, can influence technical characterictics such as performance of products and product purity to the assurance of cooling off, therefore; In the production process of plastic products, often need control, especially in the corner of product to the speed and the cooling means of cooling; In the process of plastic products cooling; Corner cooling is too fast, and the local stress that may cause plastic product is excessive and rupture, thereby can not produce qualified product according to demand.
Traditional core rod cooling structure, in application on July 5 calendar year 2001, on January 30th, 2002 was announced as its wind of king; Application number is 01113461.4; Notification number is the patent of CN1333121, and name is called die core for plastic pipe formation, it is characterized in that said core rod is a hollow tubular structures; The inner chamber of tubulose core rod is the cooling water circulation canal, and has the cooling water turnover mouth of pipe to be communicated with the circulation canal import and export respectively.This invention implements to force cooling to tubing, to improve shaping speed, to shorten the moulding distance.For condition has been created in the enforcement of some other special process.Thereby make the moulding of some special tubing become possibility.This core rod cooling device though accomplished the core rod cooling procedure in the injection molding process, is not analyzed from the mechanics angle, and very possible stress raiser at moulding causes and breaks, and causes the production disqualification rate to increase.
Summary of the invention
The utility model is bad to cooling effect in the prior art, shortcomings such as fracture appear in product easily, and a kind of injection core cooling device of the cooling control in the product corner is provided.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
The injection core cooling device comprises pedestal and core rod, is provided with cooling-water duct in the middle of the core rod, and cooling-water duct inside is equipped with water pipe, and core rod is arranged in the pedestal, is provided with nylon jacket in the core rod, and nylon jacket is arranged between water pipe and the core rod.
Core rod is installed in mould inside, is used for cooling off the product that injection moulding is produced, and adopts the method for current that mould is cooled off; Cooling water is from being installed in the inner water pipe turnover of core rod; Cooling water is in the inner cavity flow mistake of core rod, thereby mould is cooled off, and on the circulation passage of cooling water, nylon jacket is installed; Be used for adjusting water velocity, and reach the effect of control cooling velocity.
As preferably, water pipe comprises water inlet and delivery port, and water pipe is provided with three fixture blocks that are uniformly distributed with, and fixture block is stuck in the delivery port place of cooling-water duct, and the lower end of water pipe and core rod inwall have the space.Water pipe is positioned in core rod inside; And need in the inner cavity of core rod, flow; So cooling water can be flowed in the cavity from water inlet with regard to needing feed pipe to flow out certain space; The most deeply locate to leave a fixed gap at water pipe, water pipe just need be stuck in the core rod opening part, through three fixture blocks that are connected on the water pipe position of water pipe is limited.
As preferably, the ladder inclined-plane is arranged on the core rod, nylon jacket and core rod inwall fit at the place, ladder inclined-plane of core rod, and nylon jacket matches with the profile on the ladder inclined-plane of core rod with the one side that core rod fits.
The profile that the ladder inclined-plane is set on mould is according to production working of plastics determines, it is convenient that being provided with of ladder inclined-plane can be that follow-up production and processing is created, and reduces production time and cost.Nylon jacket and core rod inwall fit at the place, ladder inclined-plane of core rod, and nylon jacket matches with the profile on the ladder inclined-plane of core rod with the one side that core rod fits.
Because in the process of cooling; The corner of product is easy to take place that stress is concentrated and the defective situation that causes production; And be exactly the place, ladder inclined-plane on the core rod in pairing position on the core rod, the place, ladder inclined-plane that nylon jacket is installed in core rod just can control this regional cooling effect.
As preferably, leave the slit between said nylon jacket and the water pipe.
Because the water permeability of nylon jacket is not good; Just need be in a side away from core rod; The part slot milling of just pressing close to water pipe guarantees water flow velocity; Because the existence of nylon jacket is arranged, and the core rod cooling velocity at place, ladder inclined-plane just can descend, and so just can come injecting products is cooled off with the cooling velocity of the best.According to the technical scheme of the utility model, the cooling procedure of injection core can be through crossing general goal and nylon jacket is installed optimizes properties of product being prone to local stress.
Description of drawings
Fig. 1 partly cuts open figure for the utility model embodiment's.
Fig. 2 is the profile of the utility model embodiment nylon jacket.
The toponym that each number designation referred in the above accompanying drawing is following:
1-nylon jacket, 2-delivery port, 3-water inlet, 4-core rod, 5-water pipe, 6-cooling-water duct, 41-ladder inclined-plane, 51-fixture block, 52-space, 61-slit.
The specific embodiment
Below in conjunction with attaching Fig. 1 and 2 and the specific embodiment describes in further detail the utility model:
According to attaching Fig. 1 and 2; The injection core cooling device comprises pedestal and core rod 4, is provided with cooling-water duct 6 in the middle of the core rod 4; Cooling-water duct 6 inside are equipped with water pipe 5; It is characterized in that: core rod 4 is arranged in the pedestal, is provided with nylon jacket 1 in the core rod 4, and nylon jacket 1 is arranged between water pipe 5 and the core rod 4.Water pipe 5 comprises water inlet 3 and delivery port 2, and water pipe 5 is provided with three fixture blocks that are uniformly distributed with 51, and fixture block 51 is stuck in delivery port 2 places of cooling-water duct 6, and the lower end of water pipe 5 and core rod 4 inwalls have space 52.Ladder inclined-plane 41 is arranged on the core rod 4, and nylon jacket 1 fits at 41 places, ladder inclined-plane of core rod 4 with core rod 4 inwalls, and nylon jacket 1 matches with the profile on the ladder inclined-plane 41 of core rod 4 with the one side that core rod 4 fits.Leave slit 61 between nylon jacket 1 and the water pipe 5.
Cooling water gets into water pipe 5 from water inlet 3, and the bottom that always flows to water pipe 5 gets in the cavity 6 of core rod 4, under the hydraulic pressure effect of cooling water; Cooling water flows through from cavity 6, finally flows out from delivery port 2, at delivery port 2 places; Water pipe 5 utilizes three fixture blocks 51 that the water pipe card is gone up in place so that cooling water flows in the cavity 6 from water pipe 5, and ladder inclined-plane 41 is arranged on core rod 4, is placed with nylon jacket 1 in the cavity 6; When cooling water passes through nylon jacket 1, have a spot of cooling water to infiltrate nylon jacket 1, remaining cooling water flows through through the slit 61 between nylon jacket 1 and the water pipe 5; Nylon jacket 1 has increased the thickness of ladder inclined-plane 41 place's core rods, 4 outer walls, has reduced the cooling velocity of plastic product, because nylon jacket 1 has elasticity; Therefore can be securely fixed in 41 places, ladder inclined-plane, increase the stability of core rod cooling device.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
