Description
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of mould with wide-angle oblique top.
Background technology
At present, some mould is when oblique top back-off distance is very large, and because needs depart from product completely, solution is the distance that moves up and down that (1) strengthens L2(oblique top at present) height; (2) increase the residing angle of oblique top, realize oblique ejection from product.If but increase L2 height, may cause mould too high, final injection machine is put to be entered, and increases again the waste of material height; One section of existing mold is only applicable to being no more than 15 degree, if oblique top angle strengthens, surpasses 15 when spending, and oblique top is changed by force direction, be easy to fracture, thus waste processing and material again.
Summary of the invention
The present invention is intended at least solve one of technical problem existing in prior art.
For addressing the above problem, the present invention proposes a kind of mould with wide-angle oblique top, comprising: caster; Mother module core and male die core, described mother module core is located at the below of described caster, and described male die core is located at the below of described mother module core, limits the die cavity of processed product between described mother module core and male die core, and described product has overhead kick; Male model plate, described male model plate is located at the below of described male die core; With oblique top, tilted footstock and movable block, described oblique top connects the overhead kick of described product through described male model plate and its upper end, the lower end of described oblique top and the upper end of tilted footstock are provided with ball-and-socket, the two ends of described movable block are provided with bulb, between oblique top and movable block and between tilted footstock and movable block, all by described bulb, are connected with ball-and-socket.
The mould with wide-angle oblique top according to the present invention is by adding a movable block between the oblique top original and tilted footstock, thereby reaches oblique top wide-angle, the not easily broken possibility of falling of oblique top.Between oblique top and tilted footstock and movable block, by bulb ball-and-socket, be connected, can make to occur between three universal rotational.Therefore, mould of the present invention has the oblique top of wide-angle, even if mold thickness is high, also can not realize the complete demoulding of oblique top, and oblique top fracture may greatly reduce to reduce material.
In addition, the mould with wide-angle oblique top according to the present invention also has following additional technical feature:
Preferably, the length of described movable block is 15-20mm.
Preferably, the length of described overhead kick is 5.34mm.
Preferably, described tilted footstock is arranged on ejector pin retaining plate.
Preferably, the distance that described ejector pin retaining plate moves up and down is 35mm.
Additional aspect of the present invention and advantage in the following description part provide, and part will become obviously from the following description, or recognize by practice of the present invention.
Accompanying drawing explanation
Above-mentioned and/or additional aspect of the present invention and advantage accompanying drawing below combination obviously and is easily understood becoming the description of embodiment, wherein:
Fig. 1 is the structural representation that the present invention has the mould of wide-angle oblique top.
description of reference numerals:
Caster 1; Mother module core 2; Male die core 3; Male model plate 4; Overhead kick 5; Oblique top 6; Tilted footstock 7; Movable block 8; Ejector pin retaining plate 9.
The specific embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the present invention, and can not be interpreted as limitation of the present invention.
In description of the invention, unless otherwise prescribed and limit, it should be noted that, term " installation ", " being connected ", " connection " should be interpreted broadly, for example, can be mechanical connection or electrical connection, can be also the connection of two element internals, can be to be directly connected, also can indirectly be connected by intermediary.For the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.
Below with reference to Fig. 1, describe according to a kind of mould with wide-angle oblique top of the embodiment of the present invention.As shown in Figure 1, the mould with wide-angle oblique top of the present invention comprises caster 1, mother module core 2, male die core 3, male model plate 4, overhead kick 5, oblique top 6, tilted footstock 7, movable block 8 and ejector pin retaining plate 9.
Mother module core 2 is located at the below of described caster 1, and described male die core 3 is located at the below of described mother module core 2, limits the die cavity of processed product between described mother module core 2 and male die core 3, and described product has overhead kick 5; Described male model plate 4 is located at the below of described male die core 3; Described oblique top 6 connects the overhead kick 5 of described product through described male model plate 4 and its upper end, the upper end of the lower end of described oblique top 6 and tilted footstock 7 is provided with ball-and-socket, the two ends of described movable block 8 are provided with bulb, between oblique top 6 and movable block 8 and between tilted footstock 7 and movable block 8, all by described bulb, are connected with ball-and-socket.
The mould with wide-angle oblique top according to the present invention is by adding a movable block 8 between the oblique top 6 original and tilted footstock 7, thereby reaches oblique top 6 wide-angles, the not easily broken possibility of falling of oblique top 6.Between oblique top 6 and tilted footstock 7 and movable block 8, by bulb ball-and-socket, be connected, can make to occur between three universal rotational.Therefore, mould of the present invention has the oblique top 6 of wide-angle, even if mold thickness is high, also can not realize the complete demoulding of oblique top 6, and oblique top fracture may greatly reduce to reduce material.
The length of described movable block 8 is 15-20mm.If the too high meeting of movable block 8 causes center of gravity to improve, impact is subject to force direction; If too low, oblique top 6 swings is obstructed, and limitation is very large.Concrete size according to actual needs size is adjusted, if die pitched roof is very large, also can adjust the length of washing movable block 8.
The concrete example according to the present invention, the length of described overhead kick 5 is 5.34mm.Described tilted footstock 7 is arranged on ejector pin retaining plate 9.The distance that described ejector pin retaining plate 9 moves up and down is 35mm.
Although illustrated and described embodiments of the invention, those having ordinary skill in the art will appreciate that: in the situation that not departing from principle of the present invention and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is limited by claim and equivalent thereof.
