Abstract

The utility model discloses a cooling water conveying device used for a colorful injection molding machine, comprising a rotary disc which injects water into a die, a water feeding core shaft positioned and connected with the rotary disc, a water feeding shaft sleeve sleeved on the water feeding core shaft, and a pressing cover connecting the water feeding shaft sleeve to an injection molding; the circumference of the end surface of the rotary disc is symmetrically provided with four pairs of water inlet holes and water outlet holes which are corresponding to the water inlets and water outlets of the cooled water of the injection molding die; the axes core of the rotary disc is provided with four pairs of water inlet holes and water outlet holes; the external circumference of the water feeding core shaft is provided with a ring-shaped water conveying trough; the water feeding core shaft is internally provided with a water conveying passage which is respectively communicated with the water inlet and outlet trough and the axes core water inlet and outlet holes; the water feeding shaft sleeve is internally provided with a water conveying hole; the pressing cover is provided with a water inlet hole and a water outlet hole; when the rotary disc rotats, the water inlet hole and the water outlet hole are always communicated with the injection molding die without the requirement of re-connecting with the water conveying pipeline, and cooled water can be continuously supplied to the die, thus the problem that the production efficiency is affected because the cooled water can not be provided by the cooling device in color injection is solved.

Description

The cooling water conveying device that is used for injection mold

Technical field

The utility model relates to injection machine, particularly a kind of conveying device that is used for double coloured plastic injection machine to injection mold conveying cooling water.

Background technology

In the prior art, injection machine is when producing plastic cement products, in order to shorten cool time, enhance productivity, often need in mould, offer cooling water channel, and double-colored machine be because its punch will ° carry out the injection of second kind of color again with the rotating disk Rotate 180 after inject a kind of color, the also variation thereupon of the position of the cooling nozzle on its mould, and the water supply position on the injection machine is fixed, flexible pipe can only be installed to be connected, when work, flexible pipe swings back and forth with the rotation of mould, and is not only dangerous but also not attractive in appearance, therefore, a lot of producers have to cancel cooling nozzle when designing mould, prolonged the cool time of mould, thereby influence production efficiency.

The utility model content

The technical problems to be solved in the utility model is, a kind of cooling water conveying device that overcomes above-mentioned shortcoming in the prior art is provided, can carry out continuously injection mold being carried cooling water when multi-color injection molded at double coloured plastic injection machine, need not reconnect the flow pipe road, improve production efficiency.

The technical scheme that the utility model provides is: design a kind of cooling water conveying device that is used for multi-color injection molding machine, comprise the rotating disk that injects cooling water to mould; It is characterized in that, also comprise with described rotating disk is located by connecting and send the water mandrel, be sleeved on described the sending the water axle sleeve and the described water axle sleeve that send is connected the injection mold upper press cover on the water mandrel of sending.

In above-mentioned cooling water conveying device, be arranged with on the end face periphery of described rotating disk four pairs with the corresponding paddle hole of injection mold cooling water intake-outlet, axle center part at described rotating disk is provided with four pairs of axle center part paddle holes that are communicated with described end face paddle hole, on the described excircle that send the water mandrel, be provided with the annular water delivery groove that four roads distribute vertically, wherein twice are intake chamber, twice are effluent trough in addition, in the described water transport channel that is provided with the paddle hole that is communicated with described turnover tank and described axle center part respectively in the water mandrel of sending, be provided with the water hole that is communicated with described turnover tank respectively in the water axle sleeve described sending, on described gland, be provided with and the described paddle hole that send the water hole in the water axle sleeve to be communicated with.

Implement a kind of cooling water conveying device that the utility model provides, by on rotating disk, mandrel and axle sleeve, offering the intake-outlet that is communicated with the mould intake-outlet, employing is from the mode of rotating shaft center Inlet and outlet water, shunting around rotating disk, when dial rotation, paddle hole on the rotating disk keeps connected state with injection mold all the time, need not reconnect hydraulic pipeline, can provide cooling water to mould continuously, solved when multi-color injection molded, former cooling device can not provide cooling water and influence the problem of production efficiency.

Description of drawings

Fig. 1 is the utility model cooling water conveying device front view;

Fig. 2 is the partial sectional view of conveying device shown in Figure 1;

Fig. 3 is the front view that send the water mandrel in the conveying device shown in Figure 1;

Fig. 4 is the A-A schematic diagram of Fig. 3.

The specific embodiment

As shown in Figure 1 and Figure 2,, be provided with and send water mandrel 3, gland 1, send water axle sleeve 2, mould 4 by the cooling water conveying device that the utility model provides.Cooling water is sent in the cannelure of water mandrel 3 through sending water axle sleeve 2 to flow into by the water entry that send water mandrel gland 1, being divided into four road delivery ports everywhere that flow to mould 4 then sends, and be connected with cooling water inlet on the mould, cooling water water return outlet on the same mould also respectively be arranged on rotating disk on water return outlet everywhere be connected, four road backwater flow into to merge in the cannelure during sending water mandrel 3 leads up to the delivery port outflow of sending water axle sleeve 2 and sending water mandrel gland 1; Thereby finish the cooling procedure of mould.

Fig. 3, shown in Figure 4 be the structural representation that send water mandrel 3; Axially offer 8 deep mixed water channels that send at it, wherein water channel R is consistent respectively with the degree of depth of R1, B and B2, C and C3, D and D4, be axially arranged with 4

road cannelures

31,32,33,34 in the excircle upper edge of sending water mandrel 3, wherein twice are intake chambers, and twice are effluent troughs in addition; R and R1 water channel communicate (from left to right) with first groove, and C and C3 hole communicate with second groove, and B and B2 hole communicate with the 3rd groove, and D and D4 hole communicate with the 4th groove, and its A and B, A1 and B2 form a loop respectively, and all the other in like manner.Flow into respectively in first and second cannelures by the water that send the water axle sleeve to come in use, through A, A1, C, the C3 hole is divided into four the road and flows to the water inlet that connects behind the mould on mould, equally, the backwater that flows out from the mould delivery port flows into B, B2 respectively through rotating disk 4, D, behind the D4 water channel, to converge be one the road to flow to the apopore that send water axle sleeve 2 to the effect by cannelure again, finishes cooling procedure.
