Abstract
The utility model discloses a structure of a rapid cooling reaming tooth mould, which comprises templates and a mould core among the templates and is characterized by also comprising reaming teeth, a driving device and a forced cooling loop, wherein at least one reaming tooth made of a beryllium copper material is arranged, and the reaming teeth are arranged on one of the templates together with a transmission mechanism for the reaming teeth; the driving device is linked with the transmission mechanism through a transmission part; and the forced cooling loop comprises heat dissipation cavities and air conveying pipes, wherein the heat dissipation cavities are respectively arranged in the reaming teeth; the air conveying pipes are arranged outside the reaming teeth; and the heat dissipation cavities and the air conveying pipes can be communicated to respectively form a whole gas current passage. The reaming teeth made of the beryllium copper materials are respectively and additionally provided with a forced cooling structure, so that the reaming teeth can be rapidly cooled, and the shaping precision and the mould stripping efficiency of plastic injection products are ensured, whereas inner pipes are respectively attached to the heat dissipation cavities of the reaming teeth, thereby, the heat convection efficiency of the inner walls of the reaming teeth is improved, and the cooling speed of the reaming teeth is further increased.
Description
Technical field
The utility model relates to a kind of injection mold structure, specifically is a kind of structure of quick cooling strand tooth mould.
Background technology
Quite a lot of precise injection molding spare has requirement and have internal thread when moulding, so that use machine tooth screw rather than self-tapping screw in the actual installation.So, in injection mold, must use the core/mold insert of strand tooth, affiliated facility such as driving mechanism control strand tooth mould depanning also will be arranged simultaneously and reset.
In above-described strand tooth injection mold, its strand tooth position its meat of residing product of strand tooth form core/mold insert is thick and inconsistent, and thickness is widely different sometimes, to such an extent as to each section cooling velocity is inconsistent, causes twisting and deforms after tooth is deviate from; Though it is thick even perhaps to twist tooth position meat, numerical value is all too big, to such an extent as to cooling velocity is slow, depanning efficient reduces.A kind of demand is so just arranged, make strand tooth mould possess good cooling performance, with quality and the efficient that guarantees that injecting products strand tooth is shaped.
The utility model content
At above demand, the utility model proposes a kind of structure of quick cooling strand tooth mould, its technical scheme is as follows:
A kind of structure of quick cooling strand tooth mould comprises the core rod between template, the template, also comprises:
The strand tooth (111) of beryllium copper material, at least one is placed on one of them template (103) together with its transmission mechanism (133);
Drive unit (130) is by driving member (132) and described transmission mechanism (133) interlock; And
Force cooling circuit, this pressure cooling circuit comprises the heat radiation chamber (112) in the strand tooth (111) and twists the appendix (113) of tooth outside that this heat radiation chamber (112) can be communicated with the complete current path of formation with appendix (113).
Preferred person as technical solutions of the utility model, can do following improvement:
In one preferred embodiment, described drive unit (130) and described strand tooth (111) and transmission mechanism (133) are fixed in the same one deck template (103) on the mould.
In one preferred embodiment, described drive unit (130) comprises drive motors; Described transmission mechanism (133) comprises a gear-box; Described driving member comprises a driving chain.
In one preferred embodiment, have in the heat radiation chamber (112) of described strand tooth (111) along its inner interior pipe (114) that extends.
In one preferred embodiment, described interior pipe (114) is communicated with the induction part and the outlet gas part of described appendix (113) respectively with described heat radiation chamber (112).
The beneficial effect that the utility model brings is:
1. the strand tooth of beryllium copper material adds the structure of air blast cooling, and the strand tooth can be cooled off rapidly, guarantees the forming accuracy and the depanning efficient of injecting products.
2. the subsidiary interior pipe in the heat radiation chamber of strand tooth improves strand tooth inner surface heat convection efficiency, the cooling velocity of further raising strand tooth.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Fig. 1 is the utility model embodiment synoptic chart;
Fig. 2 is that Fig. 1 embodiment twists tooth part detail view.
The specific embodiment
As shown in Figure 1, the synoptic chart of the utility model embodiment.Upper plate 101, push pedal 102 and lower plate 103 are the main template of this mould, in the core rod 108 of product 200 between upper plate 101 and push pedal 102.
Fig. 2 has showed this some details of cooling fast.In fact in the heat radiation chamber 112 of strand tooth 111, also has a coaxial interior pipe 114, should make the air-flow in the heat radiation chambeies 112 separate fully by interior pipe 114 at two rightabouts, press among the figure shown in the arrow, cold air from appendix 113 enters interior pipe 114, by interior pipe 114 chamber 112 of deeply dispelling the heat, between interior pipe 114 outer walls and heat radiation chamber 112 inwalls, blow out again, thereby get back in the direction of arrows in the lower plate 103.So just brought into play the performance of beryllium copper strand tooth 111, adopted air blast cooling, the cooling velocity of strand tooth 111 is improved greatly.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
