Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
This utility model is the oblique mould unloading structure in a kind of straight top, and as shown in Figure 2 and Figure 3, it includes die 2, the top of die 2 Portion is provided with straight jacking block groove, is provided with straight jacking block 3 in straight jacking block groove, straight jacking block 3 top be provided with product 1 bottom the product of intermediate match Groove, is provided with the pin groove 9 connected with product groove, is provided with pin 5 in pin groove 9 bottom straight jacking block 3.Pin 5 includes rear, centre Section, head section, one end of rear is fixed on the bottom of straight jacking block groove, and rear connects interlude, and interlude connects head section, from rear to Head section attenuates successively, and the interlude of pin 5 is cased with pin spring 4, and the thickness of interlude is more than the aperture of product trench bottom, head The thickness of section is less than the aperture of product trench bottom.The head end of pin 5 matches with the inclined hole A of product 1, and the tail end of pin 5 passes through Being fixed on the spacing connection of limited block 15 of the bottom of straight jacking block groove, limited block 15 is fixed on straight jacking block groove by limited block screw 16 Bottom.Straight jacking block 3 is connected by pin 6 with through the first thimble 7 bottom die 2, and the side of the first thimble 7 is provided with two For the second thimble 8 of ejecting product 1, the outward flange of product 1 is withstood in one end of the second thimble 8 through the top of die 2, and second The other end of thimble 8 is fixed on top board, and one end of the first thimble 7 sequentially passes through from the bottom to top and pushes up with straight bottom top board, die 2 Block 3 connects.The other end of the first thimble 7 is provided with projection, is provided with a up-small and down-big hole in the middle of top board, hole above less than convex The size risen, more than protruding size below hole, the first thimble 7 can move up and down in the hole of top board.First thimble 7 The other end is fixing with the thimble screw 14 that can slide up and down in dynamic mould fixing plate 12 to be connected, and the first thimble 7 is cased with thimble Spring 13, thimble spring 13 is located between projection and dynamic mould fixing plate 12.Dynamic mould fixing plate 12 is provided with two through apical pores. Top board is made up of with Ejector Retainer Plate 11 ejector retainner plate 10, and ejector retainner plate 10 is located at Ejector Retainer Plate 11 and above and is connected with Ejector Retainer Plate 11, The other end of the second thimble 8 is connected through ejector retainner plate 10 with Ejector Retainer Plate 11.
Its ejection die, after injection completes, is divided into two steps by product 1:
The first step: upwards pushed up by Ejector Retainer Plate 11 by two through apical pores on dynamic mould fixing plate 12, drives two The product 1 that second thimble 8 props up above it upwards pushes up;Simultaneously as Ejector Retainer Plate 11 upwards pushes up, decrease and be applied at thimble Pressure on spring 13 so that the first push rod 7 is upwards pushed up by thimble spring 13 by its elastic force, in causing straight jacking block 3 and die 2 Straight jacking block groove slowly separate, the head end of pin 5 is slowly extracted out by the elastic force of pin spring 4 in the inclined hole A of product 1, as Shown in Fig. 4.
Second step: after the head end of pin 5 is extracted out completely in the inclined hole A of product 1, continues upwards to push up Ejector Retainer Plate 11, Now, owing to being stuck under the position-limiting action in dynamic mould fixing plate 12 with the first fixing thimble screw 14 being connected of push rod 7 so that straight Jacking block 3 no longer moves up;And product 1 will continue through the second thimble 8 and upwards push up so that the centre position of product 1 and Zhi Ding The product groove at block 3 top slowly departs from, until the smooth depanning of product 1, as shown in Figure 5.
This utility model ensure that die sinking and the return of out-of-order, it is to avoid complicated structure.This structure entirety is used skilful Wonderful, die sinking distance and stroke make adjustment, evades the unsafe factor that mould is a lot, it is achieved that automatically produce, greatly Improve greatly production efficiency.
