Abstract

The present invention relates to a kind of injection machine for making footwear, it comprises and a series ofly is contained in a mould on the runing rest, and two pairs of syringes that are arranged in corresponding to even number mould distance.This injector can be made monochromatic footwear in the high yield cycle, or with 4 kinds of combinations produce two-coloured shoes that difference is possible, also can two kinds of different combinations produce three look footwear.

Description

Injection machine for making footwear

The invention provides a kind of injection machine for making footwear, by this injector, available direct injection is produced the footwear of various combinations such as single, double and three looks.

The characteristics of injector of the present invention are the specific configurations of its parts, and this arranging can make it when monochrome is produced, and doubles standard speed work; Perhaps, when the different colours combinations produce, with normal speed work.

Know that the injector of making plastic shoes is basically by forming as lower member: a support, be equipped with a series of moulds on it, one then one on these moulds, they are associated with one or several syringe, and, when injection material turned cold, mould was opened, to take out final products.

These moulds are general to comprise a revolving part at least, so that before forwarding different moulds to injection zone, and order is made different layerings.

For example, in the time will producing double-colored product, corresponding mould forwards the contiguous first syringe place to; Injection material forms ground floor; Afterwards, support reach, make same mould forward second syringe to before, form one deck down.

Yet, because the idle time that exists in the production cycle, i.e. rotational time; The preceding shift time of syringe is so the output of this class machine is restricted.

The invention provides a kind of injection machine for making footwear,, also can obtain the different colours combination because the specific configuration of its parts both can overcome above-mentioned restriction.

For this reason, use two pairs of syringes, these syringes combine with the rotary system of support, thereby have advanced two moulds each time more.

Below, with reference to accompanying drawing the present invention is described in detail, wherein,

Fig. 1 illustrates the diagrammatic top view of injector of the present invention;

Fig. 2 illustrates the diagrammatic top view of another embodiment of injector of the present invention, and it is similar to a last injector, and constitutes with same inventive principle.

This injector is made of a runing rest basically, and a series of moulds are housed on its circumference.24 moulds are arranged in the accompanying drawings, with the numeral of order.This machine also comprises two pairs of syringes, respectively with I ₁-I ₂And I ₃-I ₄Expression.

The arrangement mode of two pairs of syringes is: the even number mould is arranged between two pairs of tactic syringes.

Because this specific configuration mode can realize the different courses of work.

For example, under the arrangement mode of Fig. 1, can finish double color injection with 4 kinds of various combinations, i.e. I ₁And I ₃, I ₁And I ₄, I ₂And I ₃, I ₂And I ₄

And in the injection of three looks, optional two kinds of combinations, that is, and I ₁, I ₂And I ₃Or I ₁, I ₂And I ₄

In order to overcome restriction from idle time, increase the output of machine, to arrange by this, support is subjected to moving of twice after each operating process, that is and, mould A will be from the position 1 moves on to position 3 after the rotation step.

In this case, just may be with I ₁And I ₂Inject being positioned at preceding two locational moulds simultaneously; With I ₃And I ₄Simultaneously the mould that is positioned on the position 5,6 is injected.

Each operation cycle finally, for example left footwear of a pair of footwear and right footwear are produced.Under syringe shown in Figure 2 is arranged situation, can carry out operation same as described above.In addition, it can produce monochromatic footwear, and improves machine production.

In fact, can use I ₁And I ₂Injection, and after support has advanced certain distance, take out oneself product through cooling, for example 8,9 taking-ups in the position, 13 and 14 inject again in the position.

When producing monochromatic footwear, output is redoublingd with uniform machinery.

More than Xu Shu embodiment is a kind of machine that 24 moulds are housed, yet clearly, the mould number can be different.

Certainly, size and material therefor also can change according to the needs of using.

Claims

1, is installed on the runing rest and a kind of injection machine for making footwear that constitutes is characterized in that provide two pairs of syringes, they are arranged apart with the spacing corresponding to the even number mould, and is associated with described mould along circumference by a series of moulds.

2, according to the injector of claim 1, it is characterized in that, provide suitable mechanism and start several syringes simultaneously, and, provide suitable mechanism support is advanced distance corresponding to one or two mould.
