Background technology

Plastics Jet forming machine ejaculator is a machine of making formed products, its formed products mainly is based on high molecular polymer material, and its finished product is to inject mould under pressure via the moulding material of plasticizing, and in die cavity solidified forming, and this ejaculator kind probably includes ejaculator, multiple jet gun ejaculator, two-stage type plunger ejaculator, two-stage type screw rod plunger ejaculator and the multi-drop rotation ejaculator etc. that depart from mold center, and the utility model is discussed at the multiple jet gun of multiple jet gun ejaculator and with the mould machine of its collocation especially.

The multiple jet gun ejaculator of present this industry, it mainly arranges in pairs or groups automatically by multiple jet gun, and the mould machine of die change penetrates operation, penetrate operating efficiency thereby improve, and at present the collocation mode of multiple jet gun and mould machine is: mould that should the mould machine is controlled this multiple jet gun carry out all around and move, thereby finish the finished product that multilayer penetrates or polychrome penetrates.But space and the power shared owing to the feed mechanism of this multiple jet gun start are very big, and the required expense height of feed mechanism of its electric power and design forward-reverse, therefore do not meet the principle of general practicality really.

The utility model content

The purpose of this utility model is the above-mentioned deficiency at prior art, proposes a kind of multiple jet gun ejaculator of the expense that reduces multiple jet gun power output and feed mechanism and the location structure of mould.

Above-mentioned purpose of the present utility model is achieved through the following technical solutions: the location structure of a kind of multiple jet gun ejaculator and mould includes:

The mould machine, it has base and the moving portion of mould movable up and down, wherein is provided with die shoe in base, and is pivoted with the die holder with some upper bolsters in the moving portion of mould;

Multiple jet gun, the die shoe of its corresponding collocation mould machine, and make multiaxis to moving;

The base upper surface of mould machine forms two corresponding parallel guide rails, and die shoe forms guide groove, this guide groove correspondence is mounted on this guide rail, be installed with drivening piece in the base side in addition, this drivening piece connects die shoe, to drive the slippage start on base of this die shoe, in view of the above, multiple jet gun only needs the single axial start, can finish the finished product that multilayer penetrates or polychrome penetrates.

Compare with prior art, the utlity model has following beneficial effect: mainly utilize drivening piece, to drive die shoe slippage start on base, make this multiple jet gun only need the single axial start, can finish the finished product that multilayer penetrates or polychrome penetrates, thereby reduce the expense of output of multiple jet gun power and feed mechanism.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

At first please cooperate and consult Fig. 1 to shown in Figure 3, the location structure of multiple jet gun ejaculator of the present utility model and mould mainly is made up of mould machine 10 and multiple jet gun 20, wherein:

This mould machine 10, it has base 11 and the moving portion 12 of mould movable up and down, wherein be provided with die shoe 13 thereon for counterdie 131 installings in base 11, and in the moving portion 12 of mould, be pivoted with die holder 14 with some upper bolsters 15, this upper bolster 15 is kept supplying the mould installing thereon, it should be noted that, base 11 upper surfaces of this mould machine 10 form two corresponding parallel guide rails 16, and these guide rail 16 inboards form guiding protruding 161, this guides protruding 161 and with base 11 upper surfaces one segment distance is arranged apart, moreover, place, bottom, two sides in this die shoe 13 forms guide groove 132, and the notch of two guide grooves 132 in the opposite direction, these guide groove 132 correspondences are mounted on this guide rail 16, and the guiding of this guide rail 16 protruding 161 is positioned at the guide groove 132 of this die shoe 13, in addition, (for example: oil hydraulic cylinder) be installed with drivening piece 17 in these base 11 sides, its depression bar 171 free ends see through spacer 18 and are connected (as shown in Figure 4) with the side of this die shoe 13, to drive the slippage start on base 11 of this die shoe 13;

This multiple jet gun 20 is penetrated rifle 21 and second to penetrate rifle 22 is that example is illustrated to include first, the die shoe 13 of these multiple jet gun 20 corresponding these mould machines 10 of collocation, and do suitable moving, to finish the finished product that multilayer penetrates or polychrome penetrates.

The above is the mutual alignment relation and the structure of each main member of the utility model.

Please cooperate Fig. 4 and shown in Figure 5 again, treat that first of the machine of penetrating 20 penetrates rifle 21 and carried out the operation that shoots material the first time more, at this moment, can control this actuator 17 is the oil hydraulic cylinder start, its die shoe 13 that connect to drive is moved right along the guide rail 16 of base 11 promptly away from the loophole of this multiple jet gun, and then, as shown in Figure 6, more control should penetrate machine 20 and carry out lateral displacement, make second penetrate 22 pairs in rifle should die shoe 13 so that carry out secondary operation that shoots material, treat that second penetrates rifle 22 location and finish, as shown in Figure 7, same this drivening piece 17 of control, make die shoe 13 be moved to the left promptly loophole along the guide rail 16 of base 11 near this multiple jet gun, by this, can carry out the operation that shoots material the second time, to finish the finished product that multilayer penetrates or polychrome penetrates, therefore, via structural design of the present utility model, make multiple jet gun only need carry out the single axial start, can finish the finished product that multilayer penetrates or polychrome penetrates, thereby reduce the expense of output of multiple jet gun power and feed mechanism, and, more can highlight the rapid and economic advantage of ejection formation machined, and be widely used in a large amount of production plastic processing goods.
