Abstract

The utility model relates to a novel injection mould plastic filling structure with an automatic stub bar abscission function. The novel injection mould plastic filling structure comprises a female die core and a male die core, wherein a cavity for producing a plastic article by injection molding is arranged between the female die core and the male die core; a horizontal runner is arranged on the male die core cavity; a male die insert is arranged at a position, at the runner, of the male die core; a blade is mounted at a position, at the connection part of the runner and the cavity, of the male die insert; the blade is a hollow rectangular frame; a knife edge is arranged on a upper side, matched with an inner hole of the hollow rectangular frame, of the runner. The novel injection mould plastic filling structure solves the problem that a product can not meet the standard when a plastic filling opening in the appearance of the product is cut off; with the adoption of the structure, the processing and the mounting are more convenient, and the core pulling type plastic filling manners such as a sliding block or a angular pin are replaced, so that the die cost is greatly reduced, the function of automatically cutting off the plastic filling opening in the die is realized, the production efficiency is improved, and the product percent of pass is increased.

Description

A kind of injection mould of Novel belt automatic cutting camera function enters plastic structure

Technical field

The utility model belongs to injection mold technical field, and the injection mould that particularly relates to a kind of Novel belt automatic cutting camera function enters plastic structure.

Background technology

The glue mode of entering of traditional injection moulding mould is all that molten plastic flows into die cavity by runner, after moulding completes, runner and product can connect together and be ejected mould, now need operating personnel that runner is cut from the cast gate of product edge, when pruning cast gate, easily injure product, cause and scrap.

When cast gate must design in product appearance side, for fear of the impact when pruning, product appearance being caused, can enter glue mode by what enter that glue mode is designed to slide block or this belt transect side core drawing structure of oblique top, the slide block of form enters glue as shown in Figure 1, allow runner slip into slide block inside, by slide block, flow into die cavity, die sinking rear slider is loosed core, and deviates from runner.Each cast gate place can have more a set of side core drawing structure like this, to mould manufacture and processing, brings more workload, also likely can strengthen the size of mould, increases die cost.

Summary of the invention

The injection mould that technical problem to be solved in the utility model is to provide a kind of Novel belt automatic cutting camera function enters plastic structure, can automatic break gate after injection moulding completes, enhance productivity and the qualification rate of product, and reduce die cost and manufacturing cycle.

The utility model solves the technical scheme that its technical problem adopts: provide a kind of injection mould of Novel belt automatic cutting camera function to enter plastic structure, comprise mother module core and male die core, it between described mother module core and male die core, is the die cavity of injection molding product, described male die core die cavity is provided with the runner of level, described male die core is positioned at runner place and is provided with male die insert, blade is equipped with in the junction that described male die insert is positioned at runner and die cavity, described blade is the rectangle framework of a hollow, and the endoporus of described blade rectangle framework hollow and the runner top that matches is provided with the edge of a knife.

Described blade endoporus both sides arrange pin-and-hole, and described blade is installed on male die insert by pin.

Described male die insert is with cushion block, and described cushion block pad, at blade opposite side, matches the die cavity after male die insert, blade and the rear profile of cushion block installation and mother module core, male die core amalgamation.

Beneficial effect

Of the present utility modelly enter glue gate form and successfully avoid pruning cast gate product appearance is impacted, save slide block, the pulled core structures such as oblique top, can also realize mould from the function of dynamic circuit breaker cast gate simultaneously, realize mould from the function of dynamic circuit breaker cast gate, save human cost, eliminated the waste that artificial pruning cast gate causes, improve qualification rate, save slide block, the pulled core structures such as oblique top, simplify mould structure, reduce die cost, shorten the Mould Machining cycle.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.

As shown in Fig. 2 to 5, a kind of injection mould of Novel belt automatic cutting camera function enters plastic structure, comprise mother module core 1 and male die core 6, between described mother module core 1 and male die core 6, it is the die cavity of injection molding product 2, described male die core 6 die cavities are provided with the runner 3 of level, described male die core 6 is positioned at runner 3 places and is provided with male die insert 7, described male die insert 7 is positioned at runner 3, with the junction of die cavity, blade 4 is housed, the rectangle framework that described blade 4 is a hollow, the endoporus of described blade 4 rectangle framework hollows and runner 3 top that matches is provided with the edge of a knife.

Described blade 4 endoporus both sides arrange pin-and-hole, and described blade 4 is installed on male die insert 7 by pin.

Described male die insert 7 is with cushion block 5, and described cushion block 5 pads, at blade 4 opposite sides, match the die cavity after male die insert 7, blade 4 and the cushion block rear profile of 5 installation and mother module core 1, male die core 6 amalgamations.

After completing 2 moulding of injection moulding process product, because blade 4 designs are at product 2 edges and die joint intersection, cast gate can have with the appearance of product a bit of distance, destroys Surface Appearance while having avoided pruning cast gate.

Because blade 4 endoporus tops are with the edge of a knife, and blade 4 itself is fixed on male model side, and product 2 is in the process being ejected, and the edge of a knife of blade 4 just in time cuts off.

Product 2 is by after ejection die completely, and the interior residue of runner 3 is completely separated with product, realized automatic break gate function.
