Description
Technical field
A kind of injection mold is the utility model is related to, specifically, more particularly to the injection mold without flash.
Background technology
Because silastic material has good oil resistant, a solvent resistance, at the same its have very outstanding ductility and
Stretch-resistance, therefore by large-scale application in machinery equipment field, especially as the seal in device, made extensively
With.
But due to the particularity of injection molding, therefore during processing enterprise carries out silicon rubber part processing, generally
It will use to identical mould when being molded with other materials.Because the characteristic between different materials is not quite similar, therefore use this
When class universal mold carries out the processing of silicon rubber part, its processing result is often all unsatisfactory.
Specifically, current processing enterprise is in the forming process of silicon rubber part of mini zone endoporus is carried out, mostly
The mould structure of push type will be used, this kind of mould is in generally three plate flat-crushing type molding structures, in the forming process of part,
First raw material is placed in the forming area of lower template plate, subsequent matched moulds pressurization makes raw material sulfidization molding.When using it is this into
When type scheme carries out Product processing, in order to ensure that the product after machining is not in scarce material problem, generally used by it
The grammes per square metre of raw material can increase by 20% on the basis of product net weight.So, the process that unnecessary raw material will pressurize in matched moulds
In overflow on the die joint of mould, formed die parting line flash, so as to cause product obstruction of inner pores, influence product use.
In summary, the shaping to silicon rubber part how is completed, while avoids endoporus present in conventional processes
The problem of obstruction, just become those skilled in the art's urgent problem to be solved.
Utility model content
The purpose of this utility model is to overcome the shortcomings of the prior art, there is provided a kind of injection mold of no flash.
The purpose of this utility model is achieved through the following technical solutions：
Injection mold without flash, including template, the template are made up of cope plate and lower template, are set in the lower template
There is die, the die cavity for forming parts is provided with the die, the original for being used for holding injection raw material is provided with the cope plate
Hopper, the raw material tank are connected by the pipeline being arranged in the cope plate with the die cavity, the raw material tank, pipeline and
Die cavity three coordinates the injection molding for completing part；The bottom of the die is at least provided with making the die and the upper mould
Two springs that the lower surface of plate is close to completely, respectively positioned at the both sides of the die bottom, and one end of the spring is fixed
In the lower template, the other end abuts with the lower surface of the die.
Preferably, the pipeline includes cast gate and runner, and the entrance of the runner is connected with the raw material tank, the runner
Outlet be connected with the entrance of the cast gate, the outlet of the cast gate is connected with the die cavity.
Preferably, cover plate is additionally provided with the cope plate, a briquetting has been bolted on the cover plate, and it is described
Briquetting is rare to be extended partially into the raw material tank.
Preferably, height of the height of the lower surface of the cover plate to the briquetting lower surface equivalent to the raw material tank
Degree.
Preferably, the upper surface of the die does not protrude from described in the die in the case of by the cope plate pressure
The distance of the upper surface of lower template is 0.5-1 millimeters.
The beneficial effects of the utility model are mainly reflected in：Exquisiteness simple in construction, by complete between die and cope plate
Full closed seamless gap fitting, it can be ensured that in injection molding process clout can not flash between die and cope plate, effectively
Ground avoids the generation of phenomena such as flash, while also greatly improves the yields of product, improves production efficiency.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Fig. 1：Overall structure sectional view of the present utility model.
Embodiment
The utility model is described in detail below with reference to embodiment shown in the drawings.But these embodiment party
Formula is not limited to the utility model, structure that one of ordinary skill in the art is made according to these embodiments, method or
Conversion functionally is all contained in the scope of protection of the utility model.
As shown in figure 1, the utility model discloses a kind of injection mold of no flash, including template, the template is by upper
Template 1 and lower template 2 are formed, and die 9 is provided with the lower template 2, the die cavity for forming parts is provided with the die 9,
It is provided with the raw material tank 4 for being used for holding injection raw material in the cope plate 1, the raw material tank 4 is by being arranged in the cope plate 1
Pipeline 5 be connected with the die cavity, the raw material tank 4, pipeline 5 and die cavity three coordinate the injection molding for completing part；Institute
Stating pipeline 5 includes cast gate 51 and runner 52, and the entrance of the runner 52 is connected with the raw material tank 4, the outlet of the runner 52
It is connected with the entrance of the cast gate 51, the outlet of the cast gate 51 is connected with the die cavity.
The bottom of the die 9 at least provided with being close to make the die 9 completely with the lower surface of the cope plate 1
Two springs 8, respectively positioned at the both sides of the bottom of die 9, and one end of the spring 8 is fixed in the lower template 2, separately
