Description
Technical field
The invention of this reality belongs to injection mold field, is combined more particularly, to one kind cooling with automatic demoulding
Injection mold.
Background technology
Injection mold is a kind of instrument for producing plasthetics, due to its production performance stable prod precision
It is higher to be easy to automated production, it is widely used in plastics automatic forming technique.Injection mold
The heat transfer of thermal equilibrium control injection machine and mould is the key for producing moulding.In order to meet to inject work
, it is necessary to there is thermoregulating system that the temperature of mould is adjusted, mould cools down for requirement of the skill to mold temperature
Conventional method be that cooling-water duct is opened up in mould, take away mould using the cooling water circulated
Heat, mould inside by plastic tape Lai heat by radiant heat transfer to material and the steel of mould,
By convection current to heat-conducting fluid, then heat is metabolized by fluid and reaches dynamic equilibrium.
In order to realize that the production automation just needs automatic dismoulding system, but existing release method is usually
, mainly will after die sinking by air pressure or hydraulic system using a set of dismoulding system is set below cover half
Casting ejects.But to be so not only that the mould form of dismoulding system complex designing or gas lead to
Road, also wants a set of hydraulic system of special configuration or pneumatic compression devices, and this undoubtedly adds setting for mould without foundation
Meter difficulty has drawn high production cost, and the unstability of system simultaneously.
The content of the invention
It is an object of the present invention to provide it is a kind of it is simple in construction, simple to operate, production efficiency is high, cheap
Automatic demoulding injection mold.
The technical scheme is that：Including alignment pin, die cavity, liftout plate, dynamic model, lower support base,
Heat dissipation channel, water inlet, dispersion pipe, delivery port, spring, clamp, counterbore, wherein the mould
Bottom be lower support base, be dynamic model above the lower support base, the upper surface surrounding of the dynamic model
Corner part sets multiple alignment pins respectively, and the upper surface center portion of dynamic model is die cavity, and die cavity lower surface is
Some counterbores, the interior installation liftout plate of counterbore, liftout plate lower surface connecting spring, spring are worn downwards
Enter the clamp of its lower surface connection simultaneously, the counterbore and heat dissipation channel through connection in counterbore, it is described to dissipate
The passage of heat is connected by dispersion pipe with water inlet and delivery port respectively.
Wherein, the ejection board size is differed within 4% with the size in old hole so that the inner surface of die cavity
Possess good sealing, further requirement liftout plate uses same material with die cavity, to ensure
The stabilization of contact gap size under high temperature, prevents the too small liftout plate in gap stuck or the excessive generation hair in gap
Side.
Wherein, the spring should be at tensioning state.
Wherein, the number of the counterbore and distribution should design according to the shape of die cavity, when making the demoulding by
Power is uniform.
Wherein, the clamp size is more than counterbore lower surface, and the upper and lower surface of clamp makes provided with through hole
Current can pass through.
The advantages of this reality is invented and beneficial effect are：By the cooling ring system reform by mould is cooled down simultaneously
It is used, the purpose of automatic demoulding is reached by the way of controlling and adjusting hydraulic pressure, mould can be being reduced
While having design difficulty, hydraulic pressure or pneumatic demoulding system and device are saved, saves production cost, fully
It is stripped using hydraulic pressure, and cleans mould, cool down casting mold, reducing flash makes plastic products Stability Analysis of Structures.

Embodiment
The specific embodiment of the present invention is elaborated below in conjunction with the accompanying drawings.
The injection mold that a kind of cooling is combined with automatic demoulding as shown in Figure 1, Figure 2, Figure 3 shows, including
Alignment pin 1, die cavity 2, liftout plate 3, dynamic model 4, lower support base 5, heat dissipation channel 6, water inlet 7,
Dispersion pipe 8, delivery port 9, spring 10, clamp 11 and counterbore 12, wherein the bottom of the mould
For lower support base 5, the lower top of support base 5 is dynamic model 4, the upper surface surrounding of the dynamic model 4
Angular position sets multiple alignment pins 1 respectively, and the upper surface center portion of dynamic model 4 is die cavity 2, the following table of die cavity 2
Face is some counterbores 12, and liftout plate 3, the lower surface connecting spring of liftout plate 3 are installed in counterbore 12
10, spring 10 down through its lower surface connects clamp 11 simultaneously in counterbore 12, the counterbore 12 with
The through connection of heat dissipation channel 6, the heat dissipation channel 6 by dispersion pipe 8 and water inlet 7 and go out respectively
The mouth of a river 9 connects.
The size of liftout plate 3 is differed within 4% with the size of counterbore 12, and the inner surface for the die cavity 2 for being is gathered around
There is good sealing, further requirement liftout plate 3 uses same material with die cavity 2, to protect
The stabilization of contact gap size under high temperature is demonstrate,proved, prevents the too small liftout plate 3 in gap stuck or the excessive production in gap
Setation side.The spring 10 should be at tensioning state.The number of the counterbore 12 is 8 two one
The arranged radiallys such as group, between every group each other 90 ° be equally spaced should, uniform force when making the demoulding.It is described
The size of clamp 6 is slightly larger than the lower surface of counterbore 12, and the upper and lower surface of clamp 6 is provided with through hole and makes current can
To pass through.
The course of work of this example：The termination of water inlet 7 is supplied water using low pressure during mold-closing injection,
The pressure of dispersion pipe 7, heat dissipation channel 6 and the lower surface of liftout plate 3 is relatively low, the 3 following table of liftout plate
The compression in face is less than the tension that spring 10 is given, and now lower platen is fitted tightly under die cavity 2
Surface, cooling system play cooling effect control mold temperature.The termination of water inlet 7 in mold process is divided
It is described using high service, the pressure rise of dispersion pipe 8, heat dissipation channel 6 and the lower surface of liftout plate 3
The demoulding that the compression on 3 following surface of liftout plate is more than tension and casting that spring 10 is given hinders
Power, liftout plate are raised above certain altitude, and casting is smoothly ejected, simultaneously because the size of clamp 11
It is that liftout plate 3 is unlikely to depart from counterbore in the presence of spring 10 more than counterbore 10.Other current
Overflow the effect for serving cleaning die cavity 3.The termination of water inlet 7 is supplied using low pressure again after completing the demoulding
Water, the pressure of dispersion pipe 8, heat dissipation channel 6 and the lower surface of liftout plate 3 reduce, 3 following table of liftout plate
The compression in face is less than the tension that spring 10 is given, and liftout plate returns to heavy in the presence of spring 8
Knockout course is completed in hole 10.
One embodiment of the present of invention is described in detail above, but the content is only the present invention's
Preferred embodiment, it is impossible to be considered as the practical range for limiting the present invention.It is all according to the present patent application model
Made equivalent change and improvement etc. are enclosed, all should still be belonged within the patent covering scope of the present invention.
