Detailed Description
In order to make the above objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.
As shown in fig. 1-3, the utility model provides a built-in draw bar device for mould, built-in draw bar device includes:
the top end of the rod sleeve 2 is fixed on the upper template 13; and
the bottom end of the pull rod 3 is fixed on the ejector plate 11, and the pull rod 3 is inserted into the rod sleeve 2 and is movably connected with the rod sleeve 2.
In some embodiments, the rod sleeve 2 is in a shape of a circular tube with an upper opening and a lower opening, an annular convex body 21 is arranged on the inner side of the bottom end of the rod sleeve 2, and the annular convex body 21 is matched with the pull rod 3.
In some embodiments, the rod sleeve 2 is fixed at the top end to the upper template 13, and at the bottom end to pass through the upper template 13 and the lower template 12 in sequence.
In some embodiments, the pull rod 3 is a round rod, and the outer diameter of the pull rod 3 is not larger than the inner diameter of the annular convex body 21.
In some embodiments, a stop ring 31 is detachably connected to the top end of the pull rod 3, the outer diameter of the stop ring 31 is larger than the inner diameter of the annular convex body 21 but smaller than the inner diameter of the rod sleeve 2, and the top end of the pull rod 3 can extend into the top end of the rod sleeve 2.
Specifically, the conventional die body 1 generally includes a base, an ejector plate 11, a lower die plate 12, an upper die plate 13, an ejector seat, an ejector pin, a return pin, a guide pillar, and the like, and the ejector pin ejects the product to be demolded by ejecting the ejector plate 11 upward to separate the upper die plate 13 from the lower die plate 12. And the space in which the ejector plate 11 can move is limited, the distance separating the upper and lower templates 13 and 12 is limited. The reason why the space in which the guide posts can be raised is also limited is to avoid the need to reassemble the upper die plate 13 after the demolding, because the upper die plate 13 and the top base are completely separated from the die main body 1. In order to make the distance between the upper and lower templates 13 and 12 larger, the die body 1 is usually made taller, so that the overall volume of the die body 1 becomes larger and the manufacturing cost becomes much higher.
The rod sleeve 2 of this embodiment is the pipe form, and the equal opening in top and bottom sets up, and the bottom inboard of rod sleeve 2 sets up cyclic annular convex body 21, and pull rod 3 sets up to the pipe form, and 3 tops of pull rod can insert into rod sleeve 2 in, and there is a spacing ring 31 on 3 tops of pull rod through threaded connection, and the cooperation of mutually of spacing ring 31 and cyclic annular convex body 21 can be so that rod sleeve 2 can not separate with pull rod 3. Fix the top of rod cover 2 in four angles departments on cope match-plate pattern 13 top, the bottom of pull rod 3 is then fixed on four angles of thimble board 11, set up corresponding through-hole on cope match-plate pattern 13 and lower bolster 12, rod cover 2 passes the through-hole of cope match-plate pattern 13 and lower bolster 12 down, pull rod 3 inserts into from the bottom of rod cover 2, the length of pull rod 3 can set up a little, make the top of pull rod 3 can be in the top of rod cover 2, can make the space maximize between cope match-plate pattern 13 and the lower bolster 12 like this. After 11 up movements certain distance at thimble board, the thimble separates certain distance with cope match-plate pattern 13 and lower bolster 12, lift certain height back up with cope match-plate pattern 13 again and decide, make 2 upward movement certain distances of rod cover, can not separate with pull rod 3 again, space grow between cope match-plate pattern 13 and the lower bolster 12 this moment makes things convenient for the drawing of patterns, and whole mould body 1 can not separate again, the drawing of patterns during operation of moulding plastics next time need not to reassemble, directly put down cope match-plate pattern 13 can. Furthermore, the pull rod 3 is not separated from the rod sleeve 2, and the pull rod 3 and the rod sleeve 2 have a guiding function on the upper template 13, so that the upper template 13 is not required to be aligned with the lower template 12 again in a laborious manner when being put down.
Because built-in during this embodiment, the space requirement to the mould is little, and the mould body 1 volume can set up a bit less, and can not influence the whole outward appearance aesthetic property of mould body 1, and it is also convenient simple to install.
The utility model also provides a mould, the mould includes mould body 1, and sets up the built-in pull rod device for mould as above any one on the mould body 1, built-in pull rod device can under the unchangeable circumstances of mould body 1 volume, increase mould body 1's drawing of patterns space.
In some embodiments, the number of built-in tie bar arrangements is four.
To sum up, the utility model comprises a rod sleeve 2 with the top end fixed on an upper template 13; and the bottom end of the pull rod 3 is fixed on the ejector plate 11, and the pull rod 3 is inserted into the rod sleeve 2 and is movably connected with the rod sleeve 2. The utility model discloses still provide a mould. By adopting the design, the size of the die can be smaller, the space is saved, the appearance of the die is not influenced, the installation is convenient, and the processing cost is lower.
The above-described embodiments are merely illustrative of one or more embodiments of the present invention, and the description thereof is more specific and detailed, but the scope of the invention is not limited thereto. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
