Abstract

The utility model discloses a multifunction adjustable injection shoes mould, which is composed of a bottom mould, a mould frame, a movable frame assembly and a mould cover. The movable frame assembly is composed of a moving frame, an elastic piece and an adjusting bolt. The movable frame is arranged between the mould cover and the mould frame. The mould frame is provided with an electric heating device. The bottom of the bottom mould is provided with the electric heating device. The cavity quantity and a foaming clearance of the injection shoes mould is adjusted, the temperature of the injectin shoes mould is controlled, the kinds of injection materials of use are enlarged and the varites of developing shoes are increased of by the structure.

Description

Multi-functional adjustable injection moulded shoes mould

The utility model relates to a kind of equipment of processing footwear, is specifically related to a kind of injection moulded shoes mould.Produce injection molding footwear such as sport footwear, dress shoes, sneakers now; its moulding all needs to finish with the injection moulded shoes mould; existing injection moulded shoes mould is made up of bed die, framed, die cap, and the footwear mould of producing double-colored or polychrome footwear also comprises by bed die lid and the colour esensitized equipment that divides colour table to form.When using this footwear mould to process footwear, because it is unadjustable to regulate the chamber amount and the foaming gap of injection moulded shoes mould, footwear mould temperature can not be controlled, and can not satisfy different injected plastics material temperature requirements, and suitable injected plastics material is more single, and range of application is narrow.

The purpose of this utility model is to provide a kind of both adjustable shoes die cavity amount and foaming gap, can control the injection moulded shoes mould of footwear mould temperature again.

Injection moulded shoes mould of the present utility model comprises bed die, is provided with framed, activity box assembly, the die cap of electric heater unit.The activity box assembly is made up of activity box and elastic component and the governor motion be located on the activity box, activity box die cap and framed between.

Adopt said structure, because activity box is provided with governor motion and elastic component, thereby adjustable shoes die cavity amount and foaming gap, the framed electric space heater that is provided with of while, the temperature of controlled shoemaking mould, satisfy the temperature requirement of different injected plastics materials, the injection moulding of applicable EVA, PU, rubber, PVC, thermoplastic and expandability foamed material.Enlarge the range of application of injection moulded shoes mould, increase the kind of exploitation footwear.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 2 is Fig. 1 vertical view;

Fig. 3 is the cutaway view along Figure 1A-A line;

Fig. 4 is the cutaway view along Figure 1B-B line;

Fig. 5 is the upward view of Fig. 1;

Fig. 6 is the structure chart of another embodiment of governor motion;

Fig. 7 is the electric heater unit second embodiment structure chart;

Fig. 8 is electric heater unit the 3rd an embodiment structure chart;

Fig. 9 is the upward view of Fig. 8;

Fig. 1 to injection moulded shoes mould shown in Figure 3 by die cap 2, activity box assembly, framed 4 and bed die 6 form, the activity box assembly is made up of activity box 3, adjusting bolt 1, compression spring 5, activity box 3 is between die cap 2 and framed 4, its middle part is the cavity of a shoe-shaped, at least four cylindrical holes 11 and at least four screwed holes distribute around the cavity, be provided with compression spring 5 in the above-mentioned cylindrical hole 11, regulate bolt 1 and be located in the above-mentioned screwed hole, the length of adjusting bolt 1 and the foaming gap sum of adjusting are less than the thickness sum of die cap 2 with activity box 3.Die cap 2 is provided with three charge doors 10, respectively there is a steam vent 9 die cap 2 front and back, the waste gas that produces in the time of can discharging injection moulding, die cap 2 also with the cylindrical hole 11 of activity box and the corresponding position of screwed hole on cylindrical hole and cylindricality counterbore are set respectively, the cylindricality counterbore is a matched in clearance with regulating cooperating of bolt 1, guarantees to regulate bolt 1 and is not blocked by the cylindricality counterbore.So just can above die cap 2, regulate chamber amount and foaming gap.

When needing to regulate foaming gap and chamber amount, unscrew and regulate bolt 1, die cap 2 moves up under the effect of compression spring 5, and foaming gap and chamber amount increase, and tighten and regulate bolt 1, and die cap 2 moves down, compressing compression spring 5, and foaming gap and chamber amount reduce.

Shown in Figure 4, on framed 4 tops, around die cavity, offer the shape groove similar 14 to die cavity, the heating wire 13 that is with earthenware 12 is set in the groove 14, a temperature controller 7 is also installed on framed 4 next door, during 13 pairs of injection moulded shoes mould heating of heating wire, can draw the temperature of injection moulded shoes mould from temperature controller 7, when the temperature of injection moulded shoes mould satisfies the temperature of injected plastics material, temperature controller 7 is cut off the electricity supply automatically, and heating wire 13 stops heat supply, when the temperature of injection moulded shoes mould is lower than the required temperature of injected plastics material, temperature controller is connected power supply automatically, continues heating, makes the temperature of injection moulded shoes mould satisfy the temperature requirement of injected plastics material.

Shown in Figure 5, the bottom of bed die 6 sets up groove, and an electric boiling plate 8 is installed in the groove, according to actual needs, bed die 6 is heated.

Fig. 6 is the another kind of embodiment of regulating foaming gap and chamber amount, carry out following change in a last embodiment: the screwed hole on the activity box changes and is made as the cylindricality counterbore, and the cylindricality counterbore changes screwed hole on the relevant position of die cap, with adjusting bolt 1 coupling, just can below activity box 3, regulate chamber amount and foaming gap.

Fig. 7 provides another embodiment of heater, promptly respectively has a groove at framed 4 front and rear wall, and electric hot plate 15 is installed in the groove, and electric hot plate is fixed on framed 4 walls.

Fig. 8 and Fig. 9 provide another embodiment of heater, promptly in framed 4 bottom, open the groove of an even depth around die cavity, are provided with an electrical bar 17 in the groove.

The injection moulded shoes mould that mixes up chamber amount and foaming gap is heated, after meeting the demands,, annotates simultaneously from three charge doors 10 of die cap 2 and to advance injected plastics material, be full of whole die cavity, formation footwear body injection moulded shoes mould shift-in workbench.

Also need to increase colour esensitized equipment when producing double-colored or double-colored above footwear, colour esensitized equipment is by the bed die lid and divide colour table to form, be positioned at bed die above, and be flexible connection between the bed die.
