Abstract
The utility model discloses a mould being clamped by an oblique surface, and the mould at least comprises two templates and one mould base, and the mould is characterized in that one surface of the template, which is opposite to a mould joint adopts an oblique surface, simultaneously the mould base also adopts a corresponding oblique surface to be matched with the oblique surface of the template, each template suffers the compression force of a nozzle in the direction of the mould joint, and the templates are integrally tightly wedged into the mould base as a wedge block. The force of the nozzle acting on the templates in injection molding can be transferred onto the mould base through the templates, so that a branch counter-force which is vertical to the oblique surface is generated by the mould base on the smooth oblique surface for the templates, surplus component force of the branch counter-force except for the component force for balancing the compression force of the nozzle on the templates is the mould clamping force, so that the mould clamping force can be multiplied by the compression force of the nozzle on the templates by analyzing the stress balance of the templates, and the mould clamping force is larger when the oblique angle is smaller. The mould device is used for injection molding, so that a special mould clamping mechanism can be omitted, the structure and the size of the injection molding machine can be simplified, and the mould is particularly suitable for a small-sized experiment injection molding system.
Description
Technical field
The utility model relates to a kind of forming materials device, particularly injection molding die device.
Background technology
Injection mo(u)lding is one of main method of plastic shaping.Injection machine is injected mould to plastics barrel in fusion from barrel through nozzle with plastic melt through screw rod, and in mould, flowing into mold cavity forming through running gate system is goods.Be anti-leak-stopping material, nozzle will compress template in the injection molding process, will lock between each template of mould.
Injection machine is powerful and celebrated with clamp force, and owing to clamp force is not done work, thereby the powerful clamping mechanism of injection machine has been wasted mass energy.In addition, powerful clamping mechanism has increased the size requirements of injection machine and mould.
Summary of the invention
The purpose of the utility model is to let template utilize the inclined-plane to pass through to become with this thrust from the thrust acquisition of nozzle the clamp force of certain multiplication factor, simplifies clamping system.
The purpose of the utility model realizes through following technical scheme: a kind of mould that utilizes the inclined-plane locked mode is provided; At least comprise two templates, a mould bases; It is characterized in that; On the template and the die joint facing surfaces adopt the inclined-plane, promptly and the angle between the die joint non-vanishing, also adopt the inclined-plane of respective angles to cooperate on the while mould bases with the inclined-plane of template, template is along the thrust that receives nozzle on the direction of die joint.
Utilize the die device of the utility model to carry out injection mo(u)lding; The active force that nozzle compresses template is delivered to mould bases through template; Cause mould bases template to be produced the support reaction perpendicular to the inclined-plane at smooth bevel; This support reaction is removed the balance nozzle outer all the other components (component) of the thrust of template promptly can be used as clamp force; Can know that according to the stress balance analysis of template clamp force size is relevant with the angle of inclination on template inclined-plane, be nozzle to template thrust big or small K times (K be nozzle to the cotangent of angle between the thrust direction of template and template inclined-plane 1/2), the more little clamp force in angle of inclination is big more.
Utilize the die device of the utility model to carry out injection mo(u)lding, can save special clamping mechanism, simplified injection machine structure and size, saved the energy loss of locked mode.

Fig. 2 is the force analysis figure of the utility model.
Among the figure: 1, template; 2, nozzle; 3, mould bases; 4, die joint; 5, inclined-plane.
The specific embodiment
Describe the specific embodiment of the utility model in detail below in conjunction with accompanying drawing.
A kind of mould that utilizes the inclined-plane locked mode; As shown in Figure 1; At least comprise that two templates 1, the contact-making surface that 3, two templates 1 of mould bases fit tightly are die joint 4, template 1 is to be close on the smooth bevel 5 of respective angles of mould bases 3 with the smooth bevel 5 at 4 one-tenth certain angles of inclination of die joint.Nozzle 2 edges of injection machine are pressed on the template 1 with die joint 4 parallel directions, the integral body that two templates 1 constitute like a voussoir wedging in mould bases 3.
As shown in Figure 2, during injection moulding, nozzle 2 edges apply F with die joint 4 parallel directions to template 1
NozzleThe clamping force of size, according to the stress balance analysis, template 1 must receive mould bases 3 along the support reaction F perpendicular to inclined-plane 5 directions
Normal direction, can know support reaction F according to force resolution
Normal directionOne of component F
Vertical componentWith F
NozzleIn the opposite direction, size is F
Nozzle1/2, support reaction F is arranged simultaneously
Normal directionAnother component F
The matched moulds componentWith F
NozzleDirection (being die joint 4 directions) is vertical, size is F
Vertical componentCot θ doubly, wherein θ is the angle of inclination of template 1 ramp 5, also is the thrust direction of nozzle 2 and the angle between template 1 ramp 5, F
The matched moulds componentAlso equal 1/2 cot θ nozzle, because θ can be very little (is 5 degree like θ), F
The matched moulds componentCan several times (θ be 5 be about 5.7 times when spending) in F
Nozzle, to satisfy the needs of locked mode between the template 1.
The inclined-plane locked mode mould of using the utility model carries out injection moulding, need not special clamping mechanism, has reduced the energy loss of injection moulding processing, has also reduced the hardware requirement to injection machine, is specially adapted to small test and uses injection molding system.
