Description

Portable secondary ejection mold

Technical field

The utility model is related to a kind of mold, particularly a kind of portable secondary ejection mold.

Background technology

The back-off for designing some protrusions for usually requiring cylindrical outer surface on certain plastic cement products, if common Mold just needs to be molded and depanning with sliding block, and by two slider box wrap moldings, but mold rear slider separately makes production automatically Pint goes out, but die parting line and above structure complexity are had on product, thus it is necessary to design a kind of suitable small lot production New mold.

Invention content

For overcome the deficiencies in the prior art, the utility model provides a kind of portable secondary ejection mold.

Technical solution is used by the utility model solves its technical problem：

Portable secondary ejection mold, it is characterised in that：Including preceding mould, rear mold, preceding mold core and rear mold core, the rear mold core In be equipped with mold insert hole, be equipped with molding assembly in the mold insert hole, the molding assembly including molding seat, forming blocks, straight tube core and with Straight tube core inlays screwed pipe core together, is equipped with forming hole in the molding seat, and the forming hole inner wall be equipped with it is cyclic annular into Type groove, the straight tube core and screwed pipe core are respectively positioned in forming hole, and the molding seat is equipped with two counter sinks, in the counter sink Screw is installed with, which connect with forming blocks, and the top pressure spring that can rise molding seat, the forming blocks are installed on screw Rear mold core bottom surface is fixed on, is equipped with blind hole among the straight tube core, thimble is located in the through-hole.

Push plate is equipped in the rear mold, described thimble one end is fixed with push plate.

The molding seat is a frustum of a cone.

The straight tube core top is equipped with tapered boss, and the screwed pipe core bottom end is equipped with the cone coordinated with the tapered boss Type hole.

The beneficial effects of the utility model are：The utility model is pushed up product by the way of secondary depanning from mold Go out, do not need to complicated design, and die parting line is not had on product.

Description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is the explosive view of the utility model；

Fig. 2 is the three-dimensional view of straight tube core and screwed pipe core；

Fig. 3 is product and straight tube core, the three-dimensional view of the injection molding of screwed pipe core.

Specific embodiment

Referring to figs. 1 to Fig. 3, the utility model discloses a kind of portable secondary ejection mold, portable Double-ejection moulds Tool including preceding mould 1, rear mold 2, preceding mold core 3 and rear mold core 4, is equipped with mold insert hole 5 in the rear mold core 4, is equipped in the mold insert hole 5 Molding assembly, the molding assembly include molding seat 6, forming blocks 7, straight tube core 8 and inlay solenoid type together with straight tube core 8 Core 9, the molding seat 6 is interior to be equipped with forming hole 10, and 10 inner wall of forming hole is equipped with cyclic annular forming tank（It is not shown in figure）, The straight tube core 8 and screwed pipe core 9 are respectively positioned in forming hole 10, and the molding seat 6 is equipped with two counter sinks 11, the counter sink Screw is installed in 11（It is not shown in figure）, which connect with forming blocks 7, and being installed on screw can rise molding seat 6 Top pressure spring（It is not shown in figure）, the forming blocks 7 are fixed on rear 4 bottom surface of mold core, are equipped among the straight tube core 8 logical Hole, thimble 12 are located in the through-hole, push plate 13 are equipped in the rear mold, described 12 one end of thimble is fixed with push plate 13.

The molding seat 6 is a frustum of a cone, more easy when molding seat 6 is being ejected in this way.

Mode that straight tube core 8 and screwed pipe core 9 are inlayed specifically, 8 top of straight tube core is equipped with tapered boss 14, 9 bottom end of screwed pipe core is equipped with the coniform hole coordinated with the tapered boss 14, and thimble 12 can pass through through-hole top pressure coniform hole Bottom surface.

The utility model principle is sketched：The tube wall of product 15 is by between 10 inner wall of forming hole and straight tube core 8 and screwed pipe core 9 The round gap of formation is molded into, and the back-off on product 15 is molded by forming tank, and 9 surface of screwed pipe core is equipped with screw thread, Screw thread can be thus molded by tube wall, and when ejecting first time, screw thread can make product 15 with screwed pipe core 9 Ejection；The depanning of this product 15 makes two bites at a cherry, and first time depanning is made after preceding mold core and rear mold core separate by top pressure spring Molding seat 6 rises about 10mm, positions molding seat 6 with 11 phase card of counter sink by the nut of screw, in this process, production Product 15 are integral with screwed pipe core 9 and are detached from straight tube core 8, so as to be empty in the pipe of 15 bottom end of product, then carry out the Double-ejection pushes thimble 12 by push plate 13, and thimble 12 pushes screwed pipe core 9, then by force by product 15 from molding seat 6 Middle ejection, because be empty in the pipe of 15 bottom end of product, thus when back-off is deviate from from forming tank, 10 inner wall of forming hole squeezes Back-off makes tube wall carry out certain compressive deformation, so as to back-off be made to deviate from from forming tank so as to make entire product 15 from molding Deviate from hole 10, then we can be manually rotated screwed pipe core 9 and exit it from product 15, so as to complete entire knockout course.

The portable secondary ejection mold provided above the utility model embodiment, is described in detail, herein In apply specific case the principle and embodiment of the utility model be expounded, the explanation of above example is only used Understand the method and its core concept of the utility model in help；Meanwhile for those of ordinary skill in the art, according to this reality With novel thought, there will be changes in specific embodiments and applications, in conclusion the content of the present specification is not It is interpreted as the limitation to the utility model.
