Specific embodiment
Below by specific embodiment and combine accompanying drawing the application is described in further detail.Described in literary composition
"front", "rear", "left", "right", " on ", D score is all with the laying state of the injection forming mold in accompanying drawing and injection forming mold
It is reference.It should be understood that these embodiments are merely to illustrate the application rather than limit scope of the present application.
The application is related to a kind of injection forming mold, and it includes template 1 and die 2, and die 2 is embedded in template 1.Specifically
Ground, this injection forming mold includes front template, front cavity, rear pattern plate and rear cavity, and wherein front cavity is embedded in front template, rear mold
Benevolence is embedded in rear pattern plate, and front template all offsets and constitutes airtight molding cavity with rear pattern plate and front cavity and rear cavity.This Shen
Please in the design of forward and backward die be substantially similar.The present embodiment, illustrates this injection forming mold taking rear pattern plate as a example
Basic structure, as depicted in figs. 1 and 2.
Specifically, this die 2 has the first baseplane, and template 1 has the second baseplane, and die 2 passes through the first baseplane
Fit with the second baseplane of template 1.This injection forming mold also includes heat-generating pipe 3, and its set-up mode can be as shown in Figure 1.
Heat-generating pipe 3 is C font, and two ends are fixed between the first baseplane and two ends and are left certain space, the body cincture of heat-generating pipe 3
The edge of the first baseplane arranges and is fixedly connected on the first baseplane.Certainly, heat-generating pipe 3 can also take other form and set
Put.Heat-generating pipe 3 is arranged on die 2 bottom margin by the application, avoids view field immediately below product, is prevented from die 2
Heart temperature is too high, is also beneficial to follow-up mould and safeguards.
As one kind improvement of the application injection forming mold, also include thermal insulation board 4, thermal insulation board 4 is fixed on die 2 and mould
Between plate 1, the heat for avoiding heat-generating pipe 3 is delivered to template 1 in a large number, make template 1 temperature too high lead to connect front template and
The guide pillar guide pin bushing of rear pattern plate burns or melts.
Further, the set-up mode of thermal insulation board 4 can be as shown in Figure 1.The shape of die 2 and template 1 is approximately rectangular
Body, the quantity of thermal insulation board 4 is four pieces, is shaped as flat board, is embedded in template 1 four sides inwall vertical with the second baseplane respectively,
Die 2 and template 1 are separated, to play the effect of protection template 1.Certainly, thermal insulation board 4 can also take other form setting.
As one kind improvement of the application injection forming mold, groove 5 is set in the first baseplane.Due to usual template material
The heat resistance of material is not so good as die material, and the purpose of so setting is to reduce the contact surface of the first baseplane and the second baseplane
Long-pending, thus reducing heat transmit from die 2 bottom surface to template 1, prevent that template 1 temperature is too high to lead to damage template 1.Preferably
Ground, groove 5 is arranged in the entire area of the first baseplane, can reduce connecing of the first baseplane and the second baseplane further
Contacting surface is amassed.It is further preferred that the set-up mode of groove 5 can be as shown in figure 1, include multiple first groove sections 51 and multiple second groove
Section 52, the extension line of each first groove section 51 and the second groove section 52 intersects, to form latticed groove 5.First groove section 51 and second
Angle between groove section 52 is preferably right angle, and so processing is relatively easy to, and under the conditions of groove section is the same number of, groove Duan
The distribution of one baseplane is the most uniform, can farthest reduce the contact area of the first baseplane and the second baseplane.When
So, groove 5 can also take other form setting.
As one kind improvement of the application injection forming mold, also include temperature sensor 6.This temperature sensor 6 is permissible
For thermoelectricity occasionally digital temperature instrument, and it is connected with outside temperature control system.For ensureing the uniformity of mould heating, temperature passes
Sensor 6 is located at the center within die 2, by monitoring die 2 internal temperature, temperature signal is sent to temperature control system
System, control the heated condition of flexible heat-generating pipe 3 further by the feedback of temperature control system, make mold cavity temperature stabilization and
Rapidly reach the injection mo(u)lding temperature needed for fibre-bearing composition material, solve the injection-molded finished surface floating fiber of fibre-bearing composition material
The impact that defect is processed to rear technique, qualification rate and first-pass yield that lifting fibre-bearing composition material injection produces, reduces cost.
As one kind improvement of the application injection forming mold, also include fixture 7, for heat-generating pipe 3 is fixed on the
One baseplane.Preferably fixture 7 along heat-generating pipe 3 bearing of trend be set to multiple.In FIG, the quantity of fixture 7 is six
Individual, the long side of wherein heat-generating pipe 3 is fixed using two fixtures 7, and two minor faces of heat-generating pipe 3 respectively adopt a fixture
7 are fixed, and two end points of heat-generating pipe 3 are respectively adopted a fixture 7 and are fixed.Certainly, fixture 7 can also adopt
Other forms and quantity setting.
As one kind improvement of the application injection forming mold, fixing groove is set in the first baseplane, for accommodating heating
Pipe 3.This fixing groove is used cooperatively with fixture 7, preferably heat-generating pipe 3 is fixed on the first baseplane.In actual production process
In, fixing groove and aforesaid groove 5 can be processed in the lump on the first baseplane, to save manufacturing procedure.
For solving the floating fibre problem in plastic product surface forming process, topmost method is to improve mold temperature, fall
Low fibrous material contact resistance with mold cavity in injection molding process, makes fiber and conventional injected plastics material in flowing
During speed difference diminish as far as possible.The heat-generating pipe 3 of the application is preferably electric heating tube, and material is preferably copper wire.So in mould
During tool processing, heat-generating pipe 3 can reach 200～300 DEG C of high temperature, makes conventional injected plastics material have thicker centre in flowing
Melting layer, and reduce the thickness on injected plastics material surface top layer, solve the floating fibre solving in plastic product surface forming process
Problem.
Therefore, the injection forming mold that the application provides carries a set of high temperature and stable mold heating system, can be true
Protect the injected plastics material of the fibre-bearing composition forming temperature required in injection mo(u)lding, solve surface floating fiber defect and rear technique is added
The impact of work, qualification rate and first-pass yield that lifting fibre-bearing composition material injection produces, reduces cost.
Although the application is open as above with preferred embodiment, it is not for limiting claim.Any this area skill
Art personnel, on the premise of conceiving without departing from the application, can make some possible variations and modification, therefore the application
Protection domain should be defined by the scope that claim is defined.
