Description

Injection molding mold for soft rubber special-shaped product

Technical Field

The utility model relates to an injection moulding field, especially a flexible glue dysmorphism product injection moulding mould.

Background

When the workpiece shown in fig. 1 is processed by using an injection molding mode, the workpiece is made of a soft rubber material and is integrally in a thin-walled cylinder shape, and the workpiece can be tightly wrapped on the insert after injection molding. Demoulding has therefore traditionally only been achieved with such workpieces in a manually assisted manner. Therefore, the production cost is increased, and the production efficiency is greatly reduced. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed can realize the drawing of patterns of flexible glue dysmorphism product with automizing to reach the forming die who uses manpower sparingly, improve purposes such as work efficiency.

The technical solution of the utility model is that: the utility model provides a flexible glue dysmorphism product injection moulding mould, is including the cover half part and the movable mould part that match each other, form die cavity, its characterized in that after cover half part and the movable mould part compound die: the movable mould part is internally provided with an ejector plate 1, the ejector plate 1 is connected with an ejector column 2, the top end of the ejector column 2 is connected with an ejector block 3, the ejector block 3 is connected with a first insert 4, the ejector block 3 is also connected with an inflation pipeline 5, the inflation pipeline 5 is communicated with an air passage arranged in the ejector block 3 and the first insert 4, the air passage penetrates through the first insert 4, the movable mould part is also connected with a slide block 6 in a sliding manner, the slide block 6 is provided with a second insert 7 matched with the first insert 4, the slide block 6 is provided with an inclined guide groove, and the fixed mould part is provided with an inclined guide post 8 matched with the inclined guide groove.

Compared with the prior art, the utility model, have following advantage:

the injection molding die for the flexible glue special-shaped product in the structural form is simple in structure, ingenious in design and reasonable in layout, solves the problems existing in the traditional die in the process of preparing flexible glue products in certain special shapes, designs a special die structure, directly ejects an insert by utilizing an ejection plate and an ejection column, creatively sets an inflatable air path in the insert, and can rapidly peel off the flexible glue product and the insert in an inflatable mode after the insert drives the flexible glue product on the insert to be separated from a movable die and a fixed die, so that the flexible glue product and the insert can be rapidly stripped by matching the action of a manipulator and the rapid demoulding action of the product can be realized. Compared with the traditional scheme, the die can greatly improve the working efficiency and reduce the labor cost, and meanwhile, the manufacturing process 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 drawings. As shown in fig. 1 to 4: an injection molding die for a soft rubber special-shaped product comprises a fixed die part and a movable die part which are matched with each other, wherein a cavity is formed after the fixed die part and the movable die part are matched, an ejector plate 1 is arranged in the movable die part, an ejector column 2 is connected to the ejector plate 1, the top end of the ejector column 2 is connected with an ejector block 3, a first insert 4 is connected to the ejector block 3, an inflation pipeline 5 is further connected to the ejector block 3, the inflation pipeline 5 is communicated with an air passage arranged in the ejector block 3 and the first insert 4, the air passage penetrates through the first insert 4, a slide block 6 is further connected to the movable die part in a sliding manner, a second insert 7 matched with the first insert 4 is arranged on the slide block 6, an inclined guide groove is formed in the slide block 6, and an inclined guide post 8 matched with the guide groove is arranged in the fixed die part.

The utility model discloses flexible glue dysmorphism product injection moulding mould's work process as follows: after the die is closed, the first insert 4 and the second insert 7 are contacted with each other to form a complete insert, a cavity between the insert and the fixed die part and the movable die part is a die cavity, a forming machine injects molten materials into the die cavity, the materials are cooled to form a product 9, and the product 9 is shown in figure 1 and is attached to the surfaces of the first insert 4 and the second insert 7;

when the mold is opened, under the action of the inclined guide post 8, the slide block 6 can drive the second insert 7 to move towards the direction away from the cavity, namely, the side core-pulling action of the second insert 7 is realized, and the second insert 7 is separated from the first insert 4 and is pulled out from the end part of the molded product 9;

after the mould is opened, the forming machine drives the ejection plate 1 to move, the ejection column 2 pushes the ejection block 3 to move together with the first insert 4 on the ejection block, the first insert 4 is released from the mould cavity, and at the moment, the product 9 is still included on the outer surface of the first insert 4; then, a manipulator 10 matched with the forming machine moves to the end part of the product 9, the port of the product 9 is clamped, an approximately closed inner cavity is formed in the product 9 at the moment, the product 9 is inflated through an inflation pipeline 5, air enters the inner cavity of the product 9 after passing through air passages in the ejection block 3 and the first insert 4, the product 9 originally attached to the first insert 4 can be separated from the first insert 4 under the action of the air, and at the moment, the manipulator 10 is only required to pull out the product 9 from the first insert 4, so that the demolding action of the product 9 is completed.
