Description
Technical field
The utility model relates to mould applications, and more particularly, it relates to a kind of injection mold.
Background technology
Injection mold is a kind of instrument of producing plasthetics, can be divided into two kinds, thermosetting plastic mould, thermoplastic plastic's mould according to its shaping characteristic, can be divided into blow mold, injection mold, draw mould, injection mould etc. according to moulding process, traditional injection mold can be divided into again two kinds of cold flowing mould channel, hot runner moulds with running gate system, for injection mold, injection mould is a kind of conventional mould.
For injection mold, conventionally adopt mold insert, and on mold insert, be provided with forming surface, play the effect of assistant formation face moulding, the mould of particularly loosing core for some housings, owing to being difficult to loose core after moulding, the mobile mold insert that has generally adopted left and right to close up carries out the moulding of moulding, but the position that the mould of this mode moulding can close up in the left and right of moulding produces a die parting line, quality and the feel of moulding are affected greatly, so the inside of housing is generally by mold insert moulding, but for needs by the large-scale cavity of mold insert moulding in housing, can there are a lot of problems, for example the melt temperature of injection machine discharging is very high, cause the temperature of mold insert very high, the cooling effect variation of moulding, finally make the moulding cannot be completely cooling, in prior art, the patent of invention that application number is " 201210418954.5 " solves the problem of mold insert excess Temperature by be provided with water route in mold insert, but the chilling temperature difference of the diverse location that can bring mold insert can be brought in the water route arranging, finally on injection molding part, produce water wave, affect product quality.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of injection mold of good cooling results.
For achieving the above object, the utility model provides following technical scheme: a kind of injection mold, comprise mould bases and several mold inserts, one end of described mold insert is forming surface, described in each, mold insert is set in parallel on mould bases, on described mould bases, be provided with at least one group of water route, described water route comprises the first water route and the second water route, in described mold insert, be provided with the cooling chamber being communicated with the second water route, between described the first water route and the second water route, be provided with penetration piece, in described penetration piece, be provided with cavity, described cavity is communicated with cooling chamber and the first water route respectively, described penetration piece runs through the second water route and arranges.
As preferably, the end of described cooling chamber and penetration piece is formed with hybrid chamber.
Further, by being formed with hybrid chamber in the end of cooling chamber and penetration piece, in the flow process of cooling water, if cooling water only moves towards single direction, cooling water can be because the problem of the problem generation layering of water temperature, by being provided with hybrid chamber, the flow direction of cooling water is in the position of hybrid chamber, can turn to, thereby the water of layering is mixed, make to be flipped to top in the water of bottom, reduce the temperature of cooling water and cooling chamber sidewall contact, hybrid chamber also has the effect at this position combination cooling water, extend the time that this position contacts with cooling water, cooling water is in all right turbulization of flowing of this position simultaneously, turbulent flow can make the cooling water of layering mix, make cooling water that internal temperature is lower instead to top, reduce the temperature of cooling water, thereby increase the cooling effect of plastic.
As preferably, described penetration piece is hollow tube, and the sidewall of described hollow tube offers the screw thread with mould bases threaded engagement.
Further, be set to hollow tube by penetration piece, thereby naturally produce the gap being communicated with the second water route, simultaneously again by cavity is opened in inner tube, thereby realize the circulation in water route, the cooling chamber of the first water route, mold insert inside and the second water route are connected, and outer tube has also played the effect of flowing out the gap of cooling water between mould bases of preventing, prevents that cooling water from affecting the normal use of mould; Be provided with screw thread by the position contacting with mould bases in inner tube, screw thread has played and has strengthened the effect that is connected power between inner tube and mould bases, play the effect that is communicated with the first pipeline and cooling chamber, the sealing effectiveness of screw thread is better, by the cooperation of inner tube, prevent that the second water route and the first water route are communicated with in inner tube position.
As preferably, on described the second water route, be provided with the sheath coordinating with hollow tube, one end of described sheath is fixedly connected with the second water route, the other end of described sheath and mold insert butt.
Further, because the gap between penetration piece and cooling chamber disconnects in mold insert position, so can seep water in this position, by be provided with the sheath coordinating with hollow tube in this position, sheath has played and has prevented that cooling water from flowing into mould bases between the lower surface of mold insert from gap, reduce the service life of mould, by being provided with sheath, played the effect of waterproof.
As preferably, described cooling chamber is notch cuttype.
Further, by the shape of cooling chamber is arranged to notch cuttype, thereby facilitate penetration piece in assembling process, in the time of assembling, can not collide with the sidewall of cooling chamber, increased the flowing velocity of cooling water in gap simultaneously.
As preferably, described sheath has radially extended to form flange.
Further, sheath has radially extended to form flange, and flange has played the effect that facilitates sheath fixing, prevents that sheath from dropping from mould bases.
As preferably, described sheath is made up of elastomeric material.
Further, the sheath of being made by elastomeric material, its can with the sidewall generation butt of hollow tube, strengthen its water resistance and sealing effectiveness.
By adopting technique scheme, by being provided with the first water route and the second water route, between the first water route and the second water route, be provided with penetration piece simultaneously, penetration piece makes the first water route be communicated with the cavity in mold insert, the first water route can be discharged by Cooling Water, also can flow into by Cooling Water, because in the time of the cavity of cooling water flow in penetration piece, can play effect cooling or heating to penetration piece cooling chamber around, prevent the chilling temperature difference in mold insert, thereby cause the chilling temperature difference of the moulding on mold insert, finally make the problem of moulding at cooling rear generation water wave, can play balanced effect to entering and leave the water temperature of mold insert by penetration piece, prevent that water temperature from producing interim variation, prevent the generation of water wave.
