Description

A kind of wallboard extrusion die with spliced transition part

Technical field

It the utility model is related to technical field of mold, more particularly to a kind of wallboard extrusion mould with spliced transition part Tool.

Background technology

Extrusion die is for completing extruding-out process, mainly using pressure by by the treated modeling such as hot melt Material is squeezed into mouth mold by tripper and is molded.The most of wallboard extrusion dies used at present, its transition part by polylith rebound Accumulation is formed, and as shown in Figures 1 to 3, the transition part of wallboard mould is made up of four pieces of accumulations of rebounds 01, between rebound 01 by Multiple screws are fixed, and four pieces of rebounds 01 collectively form a die cavity 011 and face the transition part that section is inverted trapezoidal, due to every piece of mistake Cab apron 01 is made of independent wire cutting, is then spliced into transition part, so results in：Every two pieces rebounds 01 to contact with each other The edge of die cavity 011 is it is difficult to ensure that smoothly transit, and easily formation stepped ramp type dead angle, is unfavorable for the circulation of material for making clothes, so as to cause putty.

Utility model content

The purpose of this utility model is to overcome above-mentioned technical deficiency, it is proposed that a kind of wallboard with spliced transition part Extrusion die, transition part is made up of the rebound of polylith in the prior art for solution, causes the die cavity of every two pieces of adjacent rebounds Edge easily forms dead angle, is unfavorable for the technical problem of the circulation of material for making clothes it is difficult to ensure that smoothly transit.

To reach above-mentioned technical purpose, the technical solution of the utility model provides a kind of wallboard with spliced transition part Extrusion die, including be fixedly connected sequentially from the bottom to top die body, rebound, supporting plate, mouth mold；The rebound is tight by two pieces The tactile splice plate of contiguity is formed, and the one side that two pieces of splice plates contact with each other is equipped with a groove, and two grooves surround to be formed The die cavity that one cross-sectional area gradually increases from the bottom to top.

Compared with prior art, the beneficial effects of the utility model include：The rebound of the extrusion die uses two pieces of phases The splice plate of setting is formed, the one side that splice plate contacts with each other is provided with a groove, and the groove can directly use CNC milling machine Process at one time, ensure that the shape and precision of groove, after two pieces of splice plates are had reeded one side close contact, be combined into The die cavity that one cross-sectional area gradually increases from the bottom to top, avoid the appearance at stepped ramp type dead angle.

Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining The utility model, it is not used to limit the utility model.

Fig. 4~6 are referred to, the present embodiment provides a kind of wallboard extrusion die with spliced transition part, including under The supreme die body 1 being fixedly connected sequentially, rebound 2, supporting plate 3, mouth mold 4.

Die body 1, the lower surface of the die body 1 set a charging aperture 11, and the upper surface of die body 1 sets one first clamping groove 12。

Rebound 2, the rebound 2 are made up of the splice plate 21 of two pieces of close contacts, and two splice plates 21 are mutual The one side of contact is equipped with a groove 211, and the groove 211 can be machined directly using CNC milling machine, ensure that groove 211 shape and precision, two grooves 211 surround to form the die cavity that a cross-sectional area gradually increases from the bottom to top, and when recessed When the bottom surface and two sides of groove 211 are arc-shaped curved surface, former mould is inconvenient to process by wire cutting, and the present embodiment The die cavity of rebound 2 surrounded and formed by the groove 211 on two pieces of splice plates 21, the groove 211 can pass through CNC milling machine It is processed as arbitrary smooth curve so that flowing of the hot melting plastic in die cavity is more unobstructed；The lower surface of the rebound 2 and mould The upper surface of body 1 is fixedly connected, and the upper surface of rebound 2 is fixedly connected with the lower surface of supporting plate 3, along type on the splice plate 21 The left and right sides of chamber are respectively arranged two and ranked first lock-screw 5, and first lock-screw 5 is threadedly coupled two pieces closely successively The splice plate 21 of contact, the mode of screw-threaded coupling make it that the contact of two pieces of splice plates 21 is more close；The splice plate is about 21 End is respectively equipped with a lug boss so that the upper and lower end after the mutually splicing of two pieces of splice plates 21 formed respectively second boss 212, First boss 213, the first clamping groove 12 are used for clamping first boss 213, so as to limit the rebound 2 of working condition The deformation occurred by the extruding of internal hot melting plastic；The lower end of die body 1 is equipped with upwardly multiple second lock-screws 6, Second lock-screw 6 is threadedly coupled die body 1, rebound 2 successively so that it is close overall that die body 1, rebound 2 form one Structure.

Supporting plate 3, the upper and lower end face of the supporting plate 3 are respectively fixedly connected with the lower surface of mouth mold 4, the upper end of rebound 2 Face, the lower surface of supporting plate 3 set one second clamping groove 31, and the second clamping groove 31 is used for clamping second convex 212 Platform, so as to limit the deformation that the rebound 2 of working condition is occurred by the extruding of internal hot melting plastic.

Mouth mold 4, the upper end of the mouth mold 4 are equipped with multiple 3rd lock-screws 7, the 3rd lock-screw 7 downwards Mouth mold 4, supporting plate 3, rebound 2 are threadedly coupled successively, mouth mold 4, supporting plate 3, rebound 2 is formed a close overall knot Structure.

Operation principle:Die body 1, transition are squeezed into successively from the charging aperture 11 of the lower end of die body 1 by the plastics for heating treated The inside die cavity of plate 2, supporting plate 3, finally by mouth mold 4, extrusion molding is completed, rebound 2 of the present utility model uses two pieces The splice plate 21 being oppositely arranged forms, and the one side that two pieces of splice plates 21 contact with each other is equipped with a groove 211, and the groove 211 can Directly to be processed at one time using CNC milling machine, the shape and precision of groove 211 are ensure that, two pieces of splice plates 21 are had recessed After the one side of groove 211 is in close contact, the die cavity that a cross-sectional area gradually increases from the bottom to top is combined into, avoids stepped ramp type dead angle Occur.

Specific embodiment of the present utility model described above, the restriction to scope of protection of the utility model is not formed.
