Abstract
The utility model relates to an injection head for a plastic injection moulding machine. The injection head for a plastic injection moulding machine is composed of a material supply cylinder seat, an injection head, and a spring. The upper part of the material supply cylinder seat is provided with an annular groove for containing the spring and the injection head. A bolt which is arranged on the material supply cylinder seat is positioned in the annular groove arranged on the injection head. An injection hole on the injection head is communicated with a material supply hole through a material inlet which is communicated with the injection hole. Before materials are injected, the injection head is gored by the spring. The material inlet is positioned on a small opening position on the upper end of the material supply hole, and a material inlet passage is closed. When the materials are injected, the injection head is extruded by a mould. The material inlet is positioned on a large opening position on the lower end of the material supply hole, and the material inlet passage is smooth. The injection head for a plastic injection moulding machine can prevent a cold mould from being generated when plastics flow into a mould, and the quality of products can be enhanced. The injection head for a plastic injection moulding machine is convenient to disassemble, assemble, and clean.
Description
The utility model relates to a kind of plastic rubber ejection shaping apparatus with penetrating head.
Present normally used plastic rubber ejection shaping apparatus is with penetrating head, and its inside is provided with a perforated holes, pushes mould to when feed pipe integral body, makes to penetrate head and press mould at that time, and whole feed pipe continues to push a bit of distance to mould, to form a feeding path.This kind structure when plastics spray to cab over type perforated holes time one length, easily block this perforated holes, and cleaning is difficult for owing to penetrate head originally as one; Plastics flow into and easily produce cold mould phenomenon in the mould.
The purpose of this utility model provides a kind of plastic rubber ejection shaping apparatus with the structure-improved of penetrating head, has when shooting material opening, and the function of remaining silent when not shooting material can prevent that plastics from flowing into the interior phenomenon that produces cold mould of mould, penetrates the head mounting or dismounting, cleans conveniently, and is safe and reliable.
The utility model by the feeding cylinder base, penetrate the head and spring form, the top infeed end of feeding cylinder base (1) has putting spring (3) and penetrates the annular groove (5) of head (2), this annular groove (5) is provided with two groups of parallel through holes (6) with feeding cylinder base (1) outer rim, each is organized latch (7) is set in the through hole (6), and feeding cylinder base (1) center has the feed orifice (9) that the feed end opening is big, the infeed end opening is little.Tube (11) is penetrated by the central authorities of penetrating head (2), penetrate tube (11) central upper portion and have a perforation (10), the bottom is provided with several charging apertures (12) that communicates with perforation (10), penetrate head (2) upper end and have a loam cake (13), loam cake (13) has a ring body (14) that matches with annular groove (5), loam cake (13) overhead is in the upper limb of feeding cylinder base (1), and ring body (14) outer rim has annular groove (15).
Ring body (14) with respect to the latch place has otch (18).Loam cake (13) is provided with the otch (17) parallel with the otch (16) on the ring body (14); Latch (7) is arranged in the annular groove of ring body (14); Feeding cylinder base (1) bottom feed end has the internal thread (4) that can match with plastic rubber ejection shaping apparatus: with the vertical intersection end-grain cutting of latch (7) concave surface (8) is arranged in feeding cylinder base (1) outer rim.
Because the utility model adopted above-mentioned combining structure, feeding-passage can open and close as required, thereby has avoided plastics to flow in the mould and produce cold mould phenomenon, can improve the quality of products and increase work efficiency, and can prevent material spray simultaneously, saves plastics; Penetrating head and feeding cylinder base can install and remove easily, and it is convenient to clean, and penetrates head and can change as required.
Now in conjunction with the accompanying drawings and embodiments the utility model is described as follows:
Fig. 1 is the utility model stereogram;
Fig. 2 is the utility model three-dimensional exploded view;
Profile before Fig. 3 moves for the utility model shoots material;
Profile after Fig. 4 moves for the utility model shoots material;
Fig. 5 is another embodiment of the utility model.
Spring (3) places the annular groove (5) of feeding cylinder base (1) earlier, insert again and penetrate head (2), after ring body (14) is inserted annular groove (5), make latch (7) be arranged in the annular groove (15) of ring body (14), to penetrate head (2) half-twist this moment, make the latch (7) that is exposed to annular groove (5) leave otch (16) end of ring body (14), can make and penetrate head (2) and combine with feeding cylinder base (1).Owing to have a clearance (being the width of annular groove) between the annular groove (15) of latch (7) and ring body (14), and the tube (11) of penetrating of penetrating head (2) is arranged in the feed orifice (9), before the action that shoots material, penetrate head (2) by spring (3) overhead, and have certain space with feeding cylinder base (1), under this state, to penetrate a charging aperture (12) and be positioned at the little opening part in feed orifice (9) upper end, charging aperture is closed; When shooting material action, mould will be penetrated head (2) and spring (3) extruding, make and penetrate head (2) near feeding cylinder base (1), under this state, penetrate the big opening part that a charging aperture (12) is positioned at feed orifice (9), penetrate a charging aperture (12) and communicate with feed orifice (9), feeding-passage is opened, and gets final product feeding.Penetrate head (2) when mould leaves, then, make the feeding-passage sealing and carry out next program behavior because the elastic force of spring (3) makes to penetrate on the head (2) and moves.
The head (2) of penetrating of the present utility model also can be replaced with the open head of penetrating shown in Figure 5 by above-mentioned self-closing, and at this moment, the perforation (10) of penetrating head (2) directly connects the feed control (9) of feeding cylinder base (1), is in normal open state.
