Abstract

The invention provides an ejector mechanism that is applied to molds. The ejector mechanism comprises: an upper ejector plate; a lower ejector plate connected with the upper ejector plate and also provided with a waterway and an O-shaped ring; an insert, which is movably disposed in a core insert of a mold and in contact with a product, has inclined planes on both sides, and is provided with a waterway; and an ejector block, which has one end located in the insert and the other end located in the upper ejector plate, and is also provided with a waterway and an O-shaped ring. The ejector mechanism can eject the product and also give consideration to waterway emission, so that the product can get good cooling. Besides, the ejector mechanism of the invention saves plastic cement and reduces production cost.

Description

Ejecting mechanism

[technical field]

The present invention relates to a kind of ejecting mechanism, be used to eject product.

[background technology]

In die production, when product is transparent member, in order to guarantee the outward appearance of product, thimble seal can not appear on product, and in order to eject product when the die sinking, will design a kind of auxiliary flow and come subsidiary products to eject.See also shown in Figure 1ly, it illustrates existing ejecting mechanism sketch map.In existing ejecting mechanism, around product 1, design auxiliary flow 2, on auxiliary flow 2, be provided with some thimbles 3, after the mould die sinking, thimble 3 ejects mould with product 1 under the effect of board ejecting force.

Yet when ejecting product with auxiliary flow, the cool time of product is longer, the product easy deformation, and increased the consumption of plastic cement, the waste plastic cement has increased production cost.

In view of this, be necessary to develop a kind of ejecting mechanism in fact, this ejecting mechanism both can eject product, can take into account the discharging water route again, made product can access cooling preferably, and practiced thrift plastic cement, reduced production costs.

[summary of the invention]

Therefore, the purpose of this invention is to provide a kind of ejecting mechanism, this ejecting mechanism both can eject product, can take into account the discharging water route again, made product can access cooling preferably, and practiced thrift plastic cement, reduced production costs.

Ejecting mechanism of the present invention is applied in the mould, and this ejecting mechanism comprises:

Upper plate;

Lower roof plate, it is connected with above-mentioned upper plate, in this lower roof plate, is provided with water route and O type circle;

Go into son, its activity is located in the male model benevolence of mould, and contacts with product, and this is gone into sub-both sides and is respectively an inclined-plane, goes into also to be provided with the water route in the son at this;

Jacking block, one of which end are located at and are above-mentionedly gone in the son, and the other end is located in the above-mentioned upper plate, in this jacking block, also is provided with water route and O type circle.

Preferable, the end that above-mentioned jacking block is located at into son also is provided with screw thread.

Compared to prior art, ejecting mechanism of the present invention, simple in structure, be convenient to processing, the cooling effect of product is better, and provides cost savings.

Fig. 2 illustrates ejecting mechanism matched moulds view of the present invention.

[specific embodiment]

See also shown in Figure 2, ejecting mechanism of the present invention, it is applied in the mould, this ejecting mechanism comprises:

Upper plate 40;

Lower roof plate 50, it is connected with above-mentioned upper plate 40, in this lower roof plate 50, also is provided with first water route 51, and is provided with O type circle 22, to prevent infiltration;

Go into son 10, its activity is located in the male model benevolence 30 of mould, and contacts with product 1; Be used for shaped article 1, this is gone into sub 10 both sides and is respectively the inclined-plane, and is movable smooth and easy in the male model benevolence 30 of mould to guarantee it; Go in the son 10 also to be provided with second water route 11 at this, with cooling products 1;

Jacking block 20, one of which end are located at and are above-mentionedly gone in the son 10, and are provided with screw thread; So that with go into son 10 and be connected closelyr, these jacking block 20 other ends are located in the above-mentioned upper plate 40, in this jacking block 20, also are provided with the 3rd water route 21; The 3rd water route 21 1 ends are connected with above-mentioned second water route 11; The other end is connected with above-mentioned first water route 51, in this jacking block 20, also is provided with O type circle 22, to prevent infiltration.

When the mould matched moulds, a closed circuit is formed in first water route 51, second water route 11, the 3rd water route 21, with cooling products 1; When the mould die sinking; Under the effect of board mould opening force; The male model part of mould is partly separated with master mold, and the push rod of board (figure does not show) is given upper plate 40 and lower roof plate 50 1 ejecting forces through the bottom plate 60 of mould then, under this ejecting force effect; Upper plate 40 drives jacking block 20 and goes into son 10 jointly to the direction motion near caster 70, and product 1 is ejected.

Compared to prior art, novel slide block of the present invention mechanism, simple in structure, be convenient to processing, both can eject product, can take into account the discharging water route again, make product can access cooling preferably, and practice thrift plastic cement, reduce production costs.

Claims (2)

1. ejecting mechanism is applied to it is characterized in that in the mould that this ejecting mechanism comprises:

Upper plate;

Lower roof plate, it is connected with above-mentioned upper plate, in this lower roof plate, also is provided with water route and O type circle;

Go into son, its activity is located in the male model benevolence of mould, and contacts with product, and this is gone into sub-both sides and is respectively the inclined-plane, goes into also to be provided with the water route in the son at this;

Jacking block, one of which end are located at and are above-mentionedly gone in the son, and the other end is located in the above-mentioned upper plate, in this jacking block, also is provided with water route and O type circle.

2. ejecting mechanism according to claim 1 is characterized in that, the end that above-mentioned jacking block is located at into son also is provided with screw thread.
