Abstract

The utility model discloses a plastic product concealed thimble remolding structure which belongs to the field of plastic products remolding manufacture technology. The utility model comprises a moving die and a fixed die, wherein the moving die and the fixed die cooperate to form a die space in some certain shape; the thimble is set on the moving die; the moving die is also provided with a slipper block, wherein, the slipper block is set between top of the thimble and the product. The slipper block is pulled apart by a inclined guide pole, and the thimble hides on bottom of the slipper block.In the process of molding in the utility model, the slipper block resists the molded product, and the thimble hides beneath the slipper block and participates in molding indirectly, which avoids thimble blotting and raw edges; when the remold product is needed, the slipper block slips, and the thimble moves upward to eject the product and fulfill actions of product remolding. The utility model isprovided with advantages like simple usage and reasonable structure, and appearance of the product meets requirement of smooth surface.

Description

The concealed thimble demolding structure of plastic products

Technical field

The utility model discloses the concealed thimble demolding structure of a kind of plastic products, belongs to plastic products demolding structure class manufacturing technology field.

Background technology

Mould generally is made of the die cavity of definite shape dynamic model and cover half, form an article made to order and be compressed in die cavity or expand by raw material, fixed half and moving half separation and goods are detached die cavity.For some small-sized plastic products, the position of thimble does not have the local suitably thimble of size of arranging owing to goods are too little, but goods must be deviate from die cavity, if adopt very tiny thimble (for example: diameter is below 0.3) the thimble undercapacity can occur, easily flexural deformation can't be produced smoothly under powerful injection pressure, and leaves the thimble vestige and burr occur and projection bad on goods, having influenced the outward appearance of goods, is unallowed for the high goods of appearance requirement especially.

In addition, it is thinner to process small-sized plastic products wall, and the end face of this thin matter goods wall contacts difficulty with thimble, and precision was higher when this just required thimble is set, thereby had increased the cost of design difficulty and production mould.

So, the release problems of injection mo(u)lding product is that those skilled in the art face and will solve, and especially for small-sized goods, ejection technique requires high, so proposition of the present utility model is just arranged.

Summary of the invention

At the deficiency of existing small-sized goods ejection technique, the utility model provides a kind of rational in infrastructure, concealed thimble demolding structure of the simple plastic products of the demoulding.

The utility model is achieved through the following technical solutions:

The utility model comprises dynamic model and cover half, and dynamic model and cover half cooperate the die cavity that forms definite shape, and thimble is arranged at dynamic model, also is provided with slide block on the dynamic model, and wherein, described slide block is between the top ends and goods of thimble.

Described slide block is to draw back by the Angle Pin that is arranged on the cover half, and thimble is ensconced slider bottom, and after being pulled outwardly of slide block reached the position, thimble ejected goods again.

In the new forming process of this practicality, slide block is contacted with on the moulding product, and thimble is hidden in the below of slide block, does not participate in moulding directly, avoid occurring thimble trace and burr, when needs demoulding goods, the slide block slippage, at this moment, thereby thimble moves upward and ejects goods, finishes goods demoulding action.

The utlity model has following useful effect:

1, during moulding,, avoids occurring thimble trace and burr because thimble is not participated in moulding directly;

2, because thimble is not participated in moulding directly, and the diameter of thimble can suitably strengthen, and satisfies the demand of its strength and stiffness, produce to stablize successfully and carry out.

3, the utility model use is simple, rational in infrastructure, and products appearance reaches the requirement of smooth surface.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment: structure such as Fig. 1 are to shown in Figure 5, and the utility model comprises dynamic model and cover half, and dynamic model and cover half cooperate the die cavity that forms definite shape, and thimble is arranged at dynamic model, also is provided with slide block on the dynamic model, and wherein, slide block is between the top ends and goods of thimble.Slide block is to draw back by the Angle Pin that is arranged on the cover half, and thimble is ensconced slider bottom, and after being pulled outwardly of slide block reached the position, thimble ejected goods again.

In the new forming process of this practicality, as Fig. 4, slide block is contacted with on the moulding product, and thimble is hidden in the below of slide block, do not participate in moulding directly, avoid occurring thimble trace and burr, as Fig. 5, when needs demoulding goods, the slide block slippage, at this moment, thereby thimble moves upward and ejects goods, finishes goods demoulding action.After injection mo(u)lding, the core in the injection moulded products 5 is carried out the demoulding.

The above record only for utilizing the embodiment of this origination techniques content, anyly is familiar with modification, the variation that this skill person uses this creation to do to do, and all belongs to the claim of this creation opinion, and is not limited to those disclosed embodiments.

Claims
