Abstract
The invention relates to an insert-positioning mechanism of a compaction forming die, comprising an insert and a die body. An insert die core is arranged at the tail end of an insert, and the die body is provided with a corresponding insert die core hole and mutually connected and the inset. The insert-positioning mechanism of the compaction forming die is characterized in that the insert die core is provided with at least one transverse hole in which a bulb plunger piston is assembled, and a bulb of the bulb plunger piston impacts and contacts with the inner wall of the insert die core hole when the insert die core is assembled in the insert die core hole. In the invention, the insert die core is provided with the transverse hole in which the bulb plunger piston is assembled, and when the insert die core is inserted in the insert die core hole, a spring in the bulb plunger piston impacts the bulb so that the bulb contacts with the inner wall of the insert die core hole, and the inset can not fall off from the die body due to friction.
Description
Technical field
The invention belongs to the technology of die manufacturing field, particularly relate to a kind of insert-positioning mechanism of compaction forming die.
Background technology
Compression mould is that mould is fixed on the hydraulic press, by the closing motion of hydraulic press, makes the upper and lower mould closure of mould, to the pressurization of heating of the material of putting into mold cavity, makes the material cured moulded plastic products simultaneously.Hydraulic press generally all is above-below direction motion, and when there is inserts in plastic products, and inserts is when inevitably appearing at the upper mould direction, the installation of mould inserts before the closed moulding goods with regard to difficult to solve.
Be fixed on inserts on the inserts core when packing mould into, can be subjected to the influence of gravity, may fall in the die cavity, cause mould to damage by pressure.In the prior art, for solving this type of problem, have plenty of by on mould, laying magnet, to hold the inserts core, but compression tool all will be heated to when moulding about 130 ℃-180 ℃, and under this higher temperature, magnet tends to lose magnetism, or owing to the press vibration is fallen down inserts, security is very low.Also have plenty of in addition by on the inserts core, loading onto spring leaf, rely on elastic force that the inserts core is fixed in the inserts cored hole of patrix, but it makes and use also inconveniently, have significant limitation.
Summary of the invention
The objective of the invention is at weak point of the prior art, a kind of novel structure, insert-positioning mechanism of compaction forming die reasonable in design are provided.
Purpose of the present invention realizes by following technical scheme: described insert-positioning mechanism of compaction forming die comprises inserts and mould body, the inserts tail end is provided with the inserts core, offer corresponding inserts cored hole on the mould body, inserts and mould body interconnect, it is characterized in that: offer at least one cross-drilled hole on the described inserts core, be equipped with the bulb plunger in the described cross-drilled hole, when inserts was contained in the mould body, the bulb of bulb plunger compressed the inwall of contact inserts cored hole.
Described bulb plunger comprises cylinder, stage clip, bulb, has axis hole on the cylinder, and stage clip one end is pressed in axis hole the inner, and the other end compresses bulb by liner.
As a further improvement on the present invention, described cross-drilled hole is provided with internal thread, and the bulb plunger is provided with external screw thread, and cross-drilled hole adopts with the bulb plunger and is threaded.
The present invention compared with prior art, by on the inserts core, offering cross-drilled hole and assemble the bulb plunger, when the inserts core inserts the inserts cored hole, spring compression bulb in the bulb plunger, make it to contact, rely on frictional force, inserts can not come off from mould body with the inwall of inserts cored hole.
Description of drawings
Fig. 1 is the assembling situation schematic diagram of inserts and mould body.
Fig. 2 is the schematic perspective view of inserts core of the present invention.
Fig. 3 is the structural representation of bulb plunger of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1, described insert-positioning mechanism of compaction forming die comprises inserts 4 and mould body 1, and inserts 4 tail ends are provided with inserts core 3, offers corresponding inserts cored hole 2 on the mould body 1, and inserts 4 and mould body 1 interconnect.
As shown in Figure 2, described inserts 4 tail ends are provided with inserts core 3, offer two cross-drilled holes 6 on the inserts core 3, and cross-drilled hole 6 is used to assemble bulb plunger 5.
As shown in Figure 3, described bulb plunger 5 comprises cylinder 11, stage clip 8, bulb 7, have axis hole 9 on the cylinder 11, stage clip 8 one ends are pressed in axis hole 9 the inners, the other end compresses bulb 7 by liner 10, when inserts core 3 was assemblied in the inserts cored hole 2, the bulb 7 of bulb plunger 5 compressed the inwall of contact inserts cored hole 2, relies on frictional force to make inserts 4 can not come off.
Described cross-drilled hole 6 is provided with internal thread, and bulb plunger 5 is provided with external screw thread, and cross-drilled hole 6 adopts with bulb plunger 5 and is threaded.
