Description
Technical field
The invention belongs to technical field of material formation, and in particular to a kind of forming method of injecting products and use the molding
A kind of injecting products that method obtains.
Background technique
Currently, insert molding process is the conventional process means for the moulding that production is enclosed with metal insert, by mould
The position that metal insert is reserved on tool, metal insert is embedded in mold, then injects the plastic cement material of melting in mold again
Material, can be obtained moulding after depanning.However, before depanning, metal insert expanded by heating, and plastic portions are due to being in high temperature
State and expand, during being cooled to room temperature after depanning, metal insert to the geometric center of its own shrink, plastic cement
Part is also shunk to the geometric center of its own, and since metal insert is embedded in plastic portions, when shrinking, metal is embedding
The shrinkage direction of part and the shrinkage direction of plastic portions are on the contrary, so as to cause the plastic parts point after metal insert and curing molding
From, and then form small gap.When the moulding is applied to waterproof product, water can enter product from these gaps
It is interior, it is greatly reduced so as to cause the waterproof performance of product, influences the quality of product.
Therefore it needs to propose a kind of new forming method, to solve after being molded due to metal insert and plastic cement caused by deforming
The gap generated between material.

Fig. 1 is the flow chart of the forming method of injecting products of the present invention.As shown in Figure 1, the invention proposes one
The forming method of kind of injecting products, injecting products include can plastic and at least one machinable inserts, can plastic there is cylinder
Inner wall, machinable inserts embedded in can on the cylinder shape inner wall face of plastic, and the upper edge of machinable inserts with can plastic
Inner wall flush, the forming method the following steps are included:
The matrix for making machinable inserts, make matrix include ontology and on the outer surface of ontology at least one is convex
It rises；
By can plastic be molded into the outer surface of matrix, make the protrusion on matrix be all included in can plastic inside, and it is cold
But it forms to moulding；
The inner wall of moulding is processed, whole ontologies of matrix are removed；
The inner wall of moulding is continued to be machined to compact dimensions；
The outer surface of moulding is carried out being machined to compact dimensions.
According to the demand of the inner wall of target injecting products, the external surface shape and protrusion of corresponding design ontology.Wherein,
The shape of the outer surface of ontology is designed to the shape of the inner wall of target injecting products, can reduce the manufacturing procedure in later period.It can
After plastic is molded into the outer surface of matrix, protrusion be wrapped in can plastic inside.By the ontology on matrix in addition to convex portion
Part is all after removal, and for protrusion embedded in can be in the inner wall of plastic, raised cross sectional shape is can be on the inner wall of plastic
The shape of machinable inserts, thus reach by the embedded connection of machinable inserts can plastic inner wall demand.
Fig. 2 is the structural schematic diagram of the injecting products of one embodiment of the invention.Fig. 3 is the corresponding base of injecting products in Fig. 2
The structural schematic diagram of body.As shown in Fig. 2, the target injecting products in the present embodiment include can plastic 10 and machinable inserts.Its
In, can plastic 10 be plastic material, have plasticity, machinable inserts be metal material.Can the inner wall of plastic 10 be equipped with
With inner wall be flush it is multiple in axial direction and the diamond-type metal block that arranges at equal intervals of circumferencial direction.
The matrix of corresponding metal material is made according to the structure feature of target injecting products.Due to target injecting products
Inner wall is cylindrical surface, therefore corresponding production outer surface is the ontology 20 of cylindrical surface, and outer in the cylinder of ontology 20
Surface be equipped with it is multiple in axial direction and the diamond block 21 that arranges at equal intervals of circumferencial direction.Wherein, the water chestnut on ontology 20
Inner wall of the relative positional relationship with target injecting products between the size of shape block 21, shape, quantity and multiple diamond blocks 21
Diamond-type metal block on face is consistent.The diameter dimension of ontology 20 is made smaller than the diameter ruler of the inner wall of target injecting products
It is very little, to be used to carry out whole removals to the ontology 20 after injection molding to process, it is finally reached the size needs of injecting products.
Wherein, the ontology 20 in the present embodiment is cylinder-like structure, and the outer surface of ontology 20 is equipped with and passes through numerically-controlled machine tool
Processing formed it is multiple in axial direction and the diamond block 21 that arranges at equal intervals of circumferencial direction.By ontology 21 in the present embodiment
Structure be set as cylinder-like structure and can reduce production cost, while reducing manufacturing procedure, improve processing efficiency.Of the invention
In other embodiments, corresponding ontology 21 and diamond block 22 can also be made using Shooting Technique.
Fig. 4 be Fig. 3 in matrix by can plastic injection molding after structural schematic diagram.As shown in figure 4, when ontology 20 is by all
Remove and be further worked into target injecting products inner wall diameter dimension, only reservation be embedded in can plastic 10 inner wall
Diamond block 21 after, can be formed on the inner wall of plastic 10 have it is multiple in axial direction and circumferencial direction is arranged at equal intervals
The diamond block 21 of column, and the upper edge of diamond block 21 with can the inner wall of plastic 10 be flush.The outer surface of moulding is carried out
Further processing, to meet the structure size demand of target injecting products.
In the present embodiment, the inner wall of moulding and outer surface are processed using numerically controlled lathe, can be improved processing
Efficiency.To guarantee that the inner wall of moulding can retain diamond block 21 after processing, rather than it is entirely removed, the present embodiment
In diamond block 21 upper edge away from the distance of the central axes of ontology 20 be greater than moulding cylinder shape inner wall face radius size.
It is real using the method for cutting metal by using the forming method and injecting products of injecting products of the present invention
Existing metal material and plastic material are inlayed, and the connection both made is more reliable and more stable, are improved between metal material and plastic material
The compactness of connection, effectively raises product quality.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of the claim
Subject to enclosing.
