Abstract
The utility model relates to a vertical two plate injection moulding machine, which comprises a glue shooting mechanism and a mould locking mechanism, wherein the mould locking mechanism comprises a moving mould board (4), a fixed mould board (9), a mould locking draw rod (3), mould locking oil cylinders (1) and a thimble device (5), wherein the upper end of the mould locking draw rod (3) is fixed with the moving mould board (4), the lower end is fixed with a piston (2), and the mould locking draw rod (3) passes through the fixed mould board (9); the piston is crammed into the mould locking oil cylinder (1); the mould locking mechanism is provided with two mould locking oil cylinders (1) which are respectively arranged on two opposite angles of the fixed mould board (9); the thimble device (5) is arranged in the center of the fixed mould board (9). The utility model has the technical effects that the oil cylinders are arranged on the opposite angles, the thimble device is arranged in the center of the fixed mould board (9), so a thimble oil cylinder can not need to be arranged in the fixed mould board and the number and the distribution of thimbles can be arranged according to the needs. The push-out length of the thimbles can be adjusted optionally, the push force of the thimbles for an inner push needle plate of a mould is uniform and the films of products which are carried out injection moulding operations can be easily dropped.
Description
Technical field the utility model relates to injection-moulding plastic equipment, particularly relates to the clamping mechanism of injection machine.
Vertical two board injection machines of background technology comprise top injection mechanism and following clamping mechanism, and the Mode-locking oil cylinder 1 of existing clamping mechanism ' have only is positioned at fixed form 9 ' central authorities, as shown in Figure 1.The installation site of Mode-locking oil cylinder cause push pin device can only be installed in fixed form 9 ' in, and a thimble can only be set, simultaneously the piston that this thimble also must double as thimble oil cylinder.Said structure has the following disadvantages: the length that ejects of thimble can not regulated at will, and the thimble stroke is short; Top power to ejector retainner plate in the mould is inhomogeneous; Can not adapt to the requirement of multiple plastic parts demoulding.
The summary of the invention the technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind of thimble quantity and distribute vertical two board injection machines that the length of thimble can be regulated arbitrarily can arbitrarily be set.
The utility model solve the technical problem can be by realizing by the following technical solutions:
Design, a kind of vertical two board injection machines of use comprise injection mechanism and clamping mechanism, and described clamping mechanism comprises moving die plate, fixed form, locked mode pull bar, Mode-locking oil cylinder and push pin device again; Described locked mode pull bar upper end is fixed with moving die plate, and the lower end is fixed with piston, and this locked mode pull bar passes through described fixed form, and described piston is filled in the described Mode-locking oil cylinder; Described Mode-locking oil cylinder has two, is separately positioned on two diagonal angles of described fixed form, and described push pin device is arranged on the central authorities of described fixed form.
The head outer diameter of described piston and the inwall of described Mode-locking oil cylinder are fitted, the afterbody external diameter of described piston less than but as far as possible near described head outer diameter.
Compare with prior art, technique effect of the present utility model is: the oil cylinder diagonal angle distributes, and fixed form central authorities are used to install push pin device, so the thimble oil cylinder needn't be arranged in the fixed form, and the quantity and the distribution of thimble can be set as required; The ejecting length and can regulate arbitrarily of thimble, and thimble is even to the top power of ejector retainner plate in the mould, and the product demoulding after the injection moulding is easy.
Cavity space is little under the oil cylinder, and the oil mass of injecting during die sinking seldom just can realize quick die sinking, and utilizes equipment self-weight can realize quick locked mode, thereby the utility model can save quick oil cylinder, has reduced equipment cost.
Description of drawings
Fig. 1 be prior art vertical injection molding machine Mode-locking oil cylinder 1 ' fixed form 9 ' on the installation site schematic diagram;
Fig. 2 is the vertical two board injection machine vertical section schematic diagrames of the utility model;
Fig. 3 is the installation site schematic diagram of two Mode-locking oil cylinders 1 on fixed form 9 of described vertical two board injection machines.
The specific embodiment is described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
As shown in Figures 2 and 3, vertical two board injection machines of the utility model comprise the injection mechanism on top and the clamping mechanism of bottom, and described clamping mechanism comprises moving die plate 4, fixed form 9, locked mode pull bar 3, Mode-locking oil cylinder 1 and push pin device 5 again; Described locked mode pull bar 3 upper ends and moving die plate 4 are fixing, and the lower end is fixed with piston 2, and this locked mode pull bar 3 passes through described fixed form template 9, and described piston 2 is filled in the described Mode-locking oil cylinder 1.This Mode-locking oil cylinder 1 has two, is separately positioned on two diagonal angles of described fixed form 9, and described push pin device 5 is arranged on the central authorities of described fixed form 9.
As shown in Figure 2, head 21 external diameters of described piston 2 and the inwall of described Mode-locking oil cylinder 1 are fitted, afterbody 22 external diameters of described piston 2 less than but as far as possible near described head 21 external diameters.The unique design of this piston 2 makes Mode-locking oil cylinder 4 can realize quick die sinking, utilizes equipment self-weight can realize quick locked mode, thereby can save quick oil cylinder.As shown in Figures 2 and 3, the utility model also comprises two balancing poles 6, is separately positioned on other two diagonal angles of described fixed form 9, and described two balancing poles 6 pass through described fixed form 9 respectively, and these two balancing poles, 6 upper ends are fixed with described fixed form 9 respectively.Because the 4 diagonal angle settings of two Mode-locking oil cylinders, two other diagonal angle is provided with balancing pole 6, thereby makes die sinking of the present utility model and locked mode more steady, stressed more even.
As shown in Figure 2, during locked mode, open the full liquid valve in the oil piping system, described piston 2, pull bar 3, moving die plate 4 and be installed on injection mechanism on this moving die plate 4, under the deadweight effect, move down fast, realize quick matched moulds, and then give epicoele pressurization the carrying out high-voltage lock mould of described Mode-locking oil cylinder 1.During die sinking, after actions such as pressurize, injection and cooling are finished, give the pressurization of Mode-locking oil cylinder 1 cavity of resorption, described piston 2, pull bar 3, template 4 and the injection mechanism that is installed on this template 4 move up, and realize die sinking.
