Background technology
In recent years, along with plastic mould the most powerful of micron order, the yield of plastic is increasing, and required precision is more and more higher, and the particularly mould of plastics of medical industries requires more and more higher.The plastic mould being used for producing plasthetics is important component part indispensable in the whole production process of plasthetics, and the structure of mould has directly impact to product quality and production process.The one-time formed product quantity of current needle cylinder mould is few; production efficiency is low, and generally cold runner die, molding cycle is long; injecting glue cast gate is arranged at the cylinder portion of syringe; cylinder portion is easily split due to stress, the hot flow path unprotect measure of injecting glue, fragile; the flowing of plastic cement has some setbacks; cast gate residual is many, and whole mould volume is big, and gate size is big.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of six chamber needle cylinder mould.This six chambeies needle cylinder mould cast gate is hidden, and gate vestiges is little, and molding cycle is greatly shortened, and one-time formed efficiency is high, and whole mould volume is little.
nullFor realizing above-mentioned technical purpose，Reach above-mentioned technique effect，The present invention is achieved through the following technical solutions: a kind of six chamber needle cylinder mould，Including nozzle body and six molding assemblies，Described nozzle body is cylindrical structural，Six molding assemblies are uniformly distributed in the periphery of nozzle body，And on the rear portion of this nozzle body, it is evenly distributed with six beryllium copper heads，Six molding assemblies connect one to one with six beryllium copper heads respectively，Each molding assembly includes front cavity、Rear cavity and interior core，Front cavity is provided with front mould top mold insert，Front cavity、Rear cavity and front mould top mold insert cooperatively form die cavity，This interior core is inserted in die cavity，Described nozzle body is provided with main hot flow path，The bottom of described main hot flow path be provided with six respectively with the position sub-runner one to one of beryllium copper head，Each beryllium copper head is made up of circular shell and the injecting glue core being arranged in circular shell，The outer end of injecting glue core stretches out in circular shell，And the outer end of injecting glue core connects with the rearward end of die cavity，The inside of each injecting glue core is respectively equipped with the injecting glue runner of connection corresponding with the sub-runner of nozzle body，Each injecting glue runner rearward end with the die cavity of corresponding molding assembly respectively is connected，And each sub-runner and each injecting glue runner are respectively in angularly disposed.
Further, the injecting glue core of described beryllium copper head is pointed.
Further, the rear portion of described front cavity is provided with receiving chamber, and the outer end of beryllium copper head is inserted in this receiving chamber.
The invention has the beneficial effects as follows: the needle cylinder mould of the present invention has six molding assemblies, can be with six products of one-shot forming, shaping efficiency is higher.The injecting glue runner of the injecting glue core of beryllium copper head is connected with the rearward end of the die cavity of molding assembly rather than gum-injecting port is arranged at the cylinder portion part of syringe die cavity as in the prior art, such that it is able to reduce stress, it is to avoid the damage of product.And, injecting glue core is placed in the circular shell of beryllium copper head, and injecting glue runner can be protected by circular shell, and the cast gate of injecting glue runner is hidden, and gate vestiges is little, and cast gate residual is few.It addition, the sub-runner of the injecting glue runner of beryllium copper head and nozzle body is all in angularly disposed, and the runner of plastic cement is hot flow path, thus is more beneficial for the flowing of plastic cement, reduces the resistance of plastic cement flowing.The whole mould volume of the present invention is less, and the gate diameter of injecting glue runner is less so that cast gate residual is less, and obtained product appearance is more excellent.

Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
As shown in Figures 1 to 4, a kind of six chamber needle cylinder mould, including nozzle body 1 and six molding assemblies 2, described nozzle body 1 is cylindrical structural, six molding assemblies 2 are uniformly distributed in the periphery of nozzle body 1, and on the rear portion of this nozzle body 1, it being evenly distributed with six beryllium copper heads 3, six molding assemblies 2 connect one to one with six beryllium copper heads 3 respectively.Each molding assembly 2 includes front cavity 21, rear cavity 22 and interior core 23, and front cavity 21 is provided with front mould top mold insert 24, and front cavity 21, rear cavity 22 and front mould top mold insert 24 cooperatively form die cavity, and this interior core 23 is inserted in die cavity.In the present embodiment, the rear portion of the front cavity 21 in each molding assembly 2 is provided with receiving chamber, and the outer end of each beryllium copper head 3 is inserted in the receiving chamber of the front cavity 21 in corresponding molding assembly.Described nozzle body 1 is provided with main hot flow path 11, the bottom of described main hot flow path 11 be provided with six respectively with sub-runner 12 one to one, position of beryllium copper head 3, each beryllium copper head 3 is made up of circular shell 31 and the injecting glue core 32 being arranged in circular shell 31, the outer end of injecting glue core 32 stretches out in circular shell 31, and the outer end of injecting glue core 32 connects with the rearward end of die cavity, the inside of each injecting glue core 32 is respectively equipped with the injecting glue runner 33 of connection corresponding with the sub-runner 12 of nozzle body 1, the cast gate of each injecting glue runner 33 rearward end with the die cavity of corresponding molding assembly 2 respectively is connected, and each sub-runner 12 and each injecting glue runner 33 are respectively in angularly disposed.
