Abstract
The utility model relates to a plastic extrusion die which comprises a flange plate and a machine head connecting body which are installed on a machine head of an extrusion machine, wherein a mouth die is installed in the mouth portion of the machine head connecting body, a core bar is arranged inside the mouth die, a mouth die fixing body is sleeved outside the mouth die, and an adjusting cushion block is arranged between the mouth die and the mouth die fixing body. The plastic extrusion die has the advantages that assembly is facilitated, adjustment of concentricity of the mouth die and the core bar is facilitated, sealing performance is good, and operation is convenient.
Description
Technical field
The utility model relates to the extrusion die technical field, especially relates to a kind of plastics extrusion die.
Background technology
Plastic extrusion mainly is the plasticity of utilizing plastics, makes plastics by processes such as extruder heating, melting, plasticizing, compacting, cooling and shapings, last moulding.Extrusion molding is mainly finished in handpiece body by mould; to utilize pressure, will clamp-on plug and mouthful intermode moulding by tripper through the plastics of the processing such as hot melt; yet the phenomenons such as inclined to one side wall, leakage material often can appear in traditional mould in process of production; mandrel axis and a mouthful mold shaft decentraction; it axially is difficult to coordinate with radially concerning when adjusting; adjust very difficult, time-consuming; and be not easy to form good sealing; coarsely can cause defective moulding with one heart, and then cause substandard product.
Therefore, a kind ofly be easy to realize to seal and to be convenient to adjust the appearance of concentric plastics extrusion die necessary.
The utility model content
The utility model is for solving the problems of the technologies described above, and is to provide a kind of and is easy to realize sealing and is convenient to adjust concentric plastics extrusion die.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of plastics extrusion die, comprise the ring flange and the head connector that are installed on the cross-head, installing port mould in the oral area of described head connector, in described mouthful of mould, plug is installed, wherein, outside described mouthful of mould, be arranged with a mouthful mould fixed body, between described mouthful of mould and described mouthful of mould fixed body, the adjusting cushion block be set also.
As preferred technical scheme, on described mouthful of mould fixed body, be evenly distributed with vertically two above hold down gags, the end of described hold down gag contacts with described adjusting cushion block.
As preferred technical scheme, described hold down gag is screw, and described screw is four.
As preferred technical scheme, on described mouthful of mould fixed body, radially be evenly distributed with two above adjusting devices, the end of described adjusting device contacts with described mouthful of mould.
As preferred technical scheme, described adjusting device is screw, and described screw is four.
The beneficial effect that the utlity model has is:
Be easy to assemble, be convenient to adjust the concentric and good seal performance of mouthful mould and plug, easy to operate.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model: a kind of structural representation of plastics extrusion die;
Wherein: 1-ring flange, 2-head connector, 3-mouth mould, 4-plug, 5-mouth mould fixed body, 6-regulate cushion block, 7-housing screw, 8-adjustment screw.
The specific embodiment
The below will be clearly and completely described the technical scheme among the utility model embodiment, and obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to shown in Figure 1, a kind of plastics extrusion die, comprise ring flange 1 and head connector 2, head connector 2 is comprised of mouth mould 3, plug 4, mouthful mould fixed body 5 and adjusting cushion block 6, mouth mould 3 is installed in the oral area of head connector 2, plug 4 is installed in mouthful mould 3, is provided with a mouthful mould fixed body 5 in the outer cover of mouth mould 3, also arranges between mouth mould 3 and mouthful mould fixed body 5 and regulates cushion block 6; Ring flange 1 and head connector 2 are installed on the cross-head.
In order better to regulate the position between mouthful mould fixed body 5 and the adjusting cushion block 6, the utility model proposes further improved technical scheme, on described mouthful of mould fixed body 5, be evenly distributed with vertically two above housing screws 7, shape and the size of the selective basis mouth mould fixed body 5 of housing screw 7 are distinguished to some extent, described housing screw 7 in the utility model is four, and the end of described housing screw 7 contacts with described adjusting cushion block 6.Radially be evenly distributed with two above adjustment screw 8 on described mouthful of mould fixed body 5, the described adjustment screw 8 in the utility model is four, and the end of described adjustment screw 8 contacts with described mouthful of mould 6.
When the needs adjustment is concentric, adjust four adjustment screw 8 of outlet side radial equipartition, mouthful mould is rotated around the ball pivot of its other end, convenient and swift, and bear high pressure by ball pivot one end in process of production, because the naturally concentric principle of ball pivot, it can not produce and depart from, and the adjustment cycle of corresponding whole mould prolongs greatly, by axial four uniform housing screws 7, the thrust between the sphere can be regulated, better sealing effectiveness can be realized.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
