Abstract

The utility model relates to the field of molds, in particular to an injection mold with an automatic nozzle removing function. An ejector pin plate is fixedly mounted on a mold base, an ejector pin penetrates through the inside of the ejector pin plate, the lower end of the ejector pin is tightly abutted to the upper side of the mold base, a positioning rod is fixedly mounted on the mold base, a nozzle ejector pin is mounted on the positioning rod, a movable mold is mounted at the upper end of the ejector pin and the upper end of the nozzle ejector pin, a fixed mold is mounted above the movable mold, a cavity is formed between a mold core of the fixed mold and a mold core of the movable mold, a product is positioned in the cavity, and a nozzle is positioned at the right end of the product. By the aid of the injection mold, a sprue can be automatically removed without manual removal, automatic production is realized, accordingly, production efficiency is improved, production cost is reduced, and the injection mold is applicable to producing products with higher requirements on surfaces of the finished products. In addition, the injection mold has the advantages that the injection mold is simple in operation and high in automation, working procedures are reduced, the cost is lowered, the production efficiency is enhanced, and the quality of the products of the mold is improved.

Description

The injection mold at a kind of automatic removal mouth of a river

Technical field

The utility model relates to mould applications, particularly a kind of injection mold with automatic removal mouth of a river function.

Background technology

Injection mo(u)lding is that the plastic material with the hot melt state is injected in the airtight molding space that has required form in the mould at high speed, wait the plastic material cooling curing after, open mould the plastic cement processing material that solidifies ejected, to obtain the method for moulding article.

In the prior art; Injection mold comprises cover half, dynamic model, ejecting mechanism, resetting-mechanism, guide-localization parts, cast mechanism, heat exchange mechanism etc., and wherein, cover half is provided with cover half benevolence; Dynamic model is provided with mavable module core; When cover half and dynamic model were fitted each other, cover half benevolence and mavable module core corresponding matching and the common airtight die cavity that forms were used for formed product.Ejecting mechanism comprises an ejector retainner plate, and the release link on this ejector retainner plate contacts with cover half, resets thereby promote ejector retainner plate; During die sinking, dynamic model moves backward, separates fully with dynamic model until cover half, behind certain distance, the plastic molded product in the dynamic model die cavity ejected fully makes it break away from mould.The plastic cement products that takes out needs manual removal cast gate or its to carry out secondary operations to remove cast gate with his equipment.In actual production, no matter be to remove or carry out secondary operations by hand with other equipment, all can increase production process and cost undoubtedly, extend manufacture cycle.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned not enough problem; The injection mold at a kind of automatic removal mouth of a river is provided; In order to solve exist in the prior art after the moulding product breaks away from mould, need manual or other equipment secondary operations to remove the problem of cast gate, minimizing operation; Save cost, practicality is stronger.

The technical scheme that the utility model adopts is: the injection mold at a kind of automatic removal mouth of a river; Comprise the mouth of a river, cover half, dynamic model, thimble, mouth of a river thimble, backstay, ejector retainner plate and die holder; It is characterized in that: ejector retainner plate is fixedly installed on the die holder, and thimble passes ejector retainner plate inside, and its lower end is close proximity on the die holder; Backstay is fixedly installed on the die holder, and mouth of a river thimble is installed on the backstay; Dynamic model is installed on thimble and mouth of a river thimble upper end, and cover half is installed on the dynamic model, constitutes die cavity between the die of fixed half and moving half, and goods are positioned at die cavity inside, and the mouth of a river is positioned at the goods right-hand member.

Must there be 2.5-3mm at the said mouth of a river apart from the goods most proximal end.

The utility model is simple in structure, adopts automatic water dividing gap device, for thin products; When requiring outer surface not allow gate vestiges, adopt usually and slip into push rod form cast gate, but cast gate needs the artificial removal; Adopt the utility model that cast gate is removed automatically, need not the artificial removal, realize automated production; Thereby enhance productivity, reduce production costs, and be applicable to the production of the demanding product of finished surface.

To sum up, the injection mold at the automatic removal mouth of a river that the utility model can provide is simple in structure, function is practical has simple to operately, and automation is strong, reduces operation, reduces cost, and enhances productivity, and improves the advantage of mould product quality.

Description of drawings

Accompanying drawing 1 is the structural representation of the injection mold at a kind of automatic removal mouth of a river.

Among the figure: 1, the mouth of a river 2, cover half 3, goods 4, die cavity 5, dynamic model 6, thimble 7, mouth of a river thimble 8, backstay 9, ejector retainner plate 10, die holder.

The specific embodiment

Specify the utility model below in conjunction with accompanying drawing, but the utility model is not limited to specific embodiment.

Shown in accompanying drawing 1, the injection mold at a kind of automatic removal of the utility model mouth of a river comprises the mouth of a river 1, cover half 2, dynamic model 5, thimble 6, mouth of a river thimble 7, backstay 8, ejector retainner plate 9 and die holder (10).

Ejector retainner plate 9 is fixedly installed on the die holder 10, and thimble 6 passes ejector retainner plate 9 inside, and its lower end is close proximity on the die holder 10, and backstay 8 is fixedly installed on the die holder, and mouth of a river thimble 7 is installed on the backstay; Dynamic model 5 is installed on thimble and mouth of a river thimble 7 upper ends, and cover half 2 is installed on the dynamic model, constitutes die cavity 4 between the die of cover half 2 and dynamic model 5, and goods 3 are positioned at die cavity inside, and the mouth of a river 1 is positioned at goods 3 right-hand members.

Must there be 2.5-3mm at the said mouth of a river 1 apart from goods 3 most proximal end.

Use this mould as shown in Figure 1 when the mold-closing injection moulding; Dynamic model 5 moves backward; Clearance position ejector retainner plate 9 has been done in thimble 7 belows in the mouth of a river, and mouth of a river thimble 7 was temporarily motionless when goods 3 were ejected under the effect of injector, and goods 3 are separated with cast gate by force; Mouth of a river thimble 7 ejected the mouth of a river 1 after goods 3 were ejected one section, finally reached stripping result.
