Description

Molding material-saving mold with fixed mold inclined ejection mechanism

Technical Field

The utility model relates to the injection mold industry, in particular to a mold which saves molding materials and is provided with a fixed mold inclined ejection mechanism.

Background

In the production of plastic articles using injection molds, products having a back-off structure are often encountered. Aiming at a general back-off structure, the side core pulling action at the back-off position can be realized by designing a common side core pulling structure. However, some products with special structures are partially arranged outside the inverted buckle structure (i.e. in the side core pulling direction), so that the conventional side core pulling mechanism cannot realize the action of disengaging the inverted buckle, and thus an inclined top structure needs to be arranged inside the products. And traditional oblique top structure need set up in cover half one side, and the setting of oblique top structure, need increase the polylith board in cover half part, still need flow sufficient motion space for ejection action simultaneously, consequently lead to the whole thickness greatly increased of cover half part, will let the length of runner and runner lengthen like this, length can reach more than the twice of ordinary structure under general condition, will lead to the material handle extension of staying in the runner at every turn like this, cause the waste of raw materials. When the product is made of a material with a high price, a great cost waste is caused. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects in the prior art, and provides the die which is simple in structure, ingenious in design and reasonable in layout, can be provided with a fixed die inclined top structure, and can greatly reduce the whole thickness of the side of the fixed die so as to achieve the purpose of reducing waste materials as much as possible.

The technical solution of the utility model is as follows: the utility model provides a saving forming material's mould that has cover half mechanism of pushing up to one side, includes the cover half part and the movable mould part that match each other, its characterized in that: the fixed die part comprises an upper fixed plate 1, a runner plate 2 is arranged below the upper fixed plate 1, an accommodating groove is formed in the runner plate 2, a pulling plate 3 is arranged in the accommodating groove, an A plate 4 is arranged below the runner plate 2, a first limiting bolt 5 is arranged between the upper fixed plate 1 and the runner plate 2, a second limiting bolt 6 is arranged between the upper fixed plate 1 and the pulling plate 3,

a fixed die insert 7 is fixedly connected to the bottom end surface of the pulling plate 3, an inclined surface is arranged on the fixed die insert 7 in the direction towards the cavity, a fixed die inclined top 8 is connected to the inclined surface in a sliding mode through a dovetail groove, an insert part 9 capable of extending into the cavity when die assembly is carried out is arranged at the bottom end of the fixed die inclined top 8,

a guide sleeve 10 is further arranged in the pulling plate 3, the guide sleeve 10 is slidably connected with a guide post 11, the bottom end of the guide post 11 is fixedly connected to the a plate 4, and a guide hole capable of accommodating the guide post 11 is further formed in the upper fixing plate 1.

Compared with the prior art, the utility model has the following advantages:

this kind of structural style's saving forming material's mould that has cover half mechanism of pushing up to one side, a structure is simple, design benefit, reasonable in layout, it needs to set up the polylith board to traditional cover half mechanism of pushing up to one side, and need leave the motion space of pushing up the ejecting action to one side and lead to the increase of the whole thickness in cover half side, and then cause the extravagant problem of material, a special structure is designed, it has seted up the holding tank in the runner board, and the direct drive pushes up the mechanism action to one side draws the board and then sets up in this holding tank, under the compound die state, draw the board and be in same level with the runner board, this kind of structure can be under the prerequisite that does not increase the whole thickness of cover half part, realize the side action of loosing core of pushing up the mechanism to one side, and then reach control runner length, save material, reduce cost's purpose. And the manufacturing process of the die is simple, the manufacturing cost is low, so that the die has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.

Detailed Description

The following description will explain embodiments of the present invention with reference to the accompanying drawings. As shown in fig. 1 to 4: a die with a fixed die inclined ejection mechanism for saving molding materials comprises a fixed die part and a movable die part which are matched with each other, wherein the fixed die part comprises an upper fixed plate 1, a runner plate 2 is arranged below the upper fixed plate 1, a containing groove is formed in the runner plate 2, a pulling plate 3 is arranged in the containing groove, an A plate 4 is arranged below the runner plate 2, a first limit bolt 5 is arranged between the upper fixed plate 1 and the runner plate 2, a second limit bolt 6 is arranged between the upper fixed plate 1 and the pulling plate 3,

The working process of the die with the fixed die inclined ejection mechanism for saving molding materials in the embodiment of the utility model is as follows: in a mold closing state (as shown in figure 1), an insert part 9 at the bottom end of a fixed mold inclined top 8 extends into a cavity and forms a part of the cavity, an injection molding machine injects molten materials into the cavity through a material channel, and the materials are cooled to form a product;

when the mold is opened (as shown in figure 2), the upper fixing plate 1 and the runner plate 2 are opened first, the fixed mold inclined top 8 does not act at the moment,

when the distance between the upper fixing plate 1 and the runner plate 2 reaches the triggering distance of the first limiting bolt 5, the runner plate 2 is driven to move upwards together (as shown in fig. 3), the runner plate 2 moves upwards and is separated from the pulling plate 3 in the accommodating groove, the pulling plate 3 does not move, the fixed die inclined top 8 does not move,

when the distance between the upper fixing plate 1 and the pulling plate 3 reaches the triggering distance of the second limiting bolt 6, the pulling plate 3 is driven to move upwards together (as shown in fig. 4), the pulling plate 3 moves upwards and drives the fixed mold insert 7 connected to the bottom end face of the pulling plate to move upwards, and as the inclined plane arranged on one side of the fixed mold insert 7 is slidably connected with the fixed mold inclined top 8 through the dovetail groove, and the fixed mold inclined top 8 cannot move longitudinally at the moment, the inclined plane can move horizontally under the action of the inclined dovetail groove, so that the insert part 9 at the bottom end of the fixed mold inclined top 8 can be drawn out of a product, and side core pulling action is realized;

when the mold is closed, the movement is reversed, all the mechanisms return to the state shown in fig. 1, and the next injection molding operation is waited.

Because the pulling plate 3 enters the accommodating groove arranged in the runner plate 2 in the matched die state, namely the two are positioned on the same horizontal plane, the longitudinal space can be greatly saved, namely the whole thickness of the fixed die part is not additionally increased, and therefore, the runner part of the die can not be prolonged compared with the runner part of a common die, and the purpose of saving materials can be achieved.
