Description

Technical Field

[0001] The present invention relates to the technical field of injection molding, and particularly to a hardware handle. Background Art

[0002] In order to meet the corresponding usage requirements, existing hardware handles are provided with hardware parts as inner brackets inside the hardware handles, and the hardware handles are obtained by injection molding. In subsequent high and low temperature tests, after a certain period of high and low temperature conversion, cracking will occur, which does not meet the requirements. At the same time, due to problems such as uneven plastic flow on the surface of the product, defects such as flow marks will appear on the plastic high-gloss surface, affecting the product quality.

[0003] Therefore, there are defects in the prior art and improvements are needed. Summary of the Invention

[0004] The purpose of the present invention is to overcome some deficiencies of the prior art and provide a hardware handle.

[0005] The technical solution of the present invention is as follows: The present invention provides a hardware handle, and the manufacturing steps of the hardware handle are: providing a plastic inner bracket, placing the plastic inner bracket in an injection mold for injection molding, and obtaining the hardware handle after cooling.

[0006] Further, the material of the plastic inner bracket is PC (polycarbonate).

[0007] Further, when there are appearance defects in the hardware handle, the position of the plastic inner bracket is finely adjusted.

[0008] Further, during the molding process of the hardware handle, an auxiliary shaping fixture is used to shape the hardware handle during the molding process.

[0009] Further, a glue flow groove for facilitating glue flow is provided in the plastic inner bracket.

[0010] By adopting the above scheme, the beneficial effects of the present invention are as follows: By using a plastic inner bracket, the yield rate of the product during high and low temperature shock tests is increased from 30% to about 80%, and the surface appearance quality of the product is also improved. The injection molding cooling time is reduced, and the product cost is also reduced. It is also convenient to recycle the materials for defective products. Detailed Description

[0011] The following will describe the present invention in detail with reference to specific embodiments.

[0012] In this embodiment, the present invention provides a hardware handle. The manufacturing steps of the hardware handle are as follows: providing a plastic inner bracket, placing the plastic inner bracket in an injection mold for injection molding, and obtaining the hardware handle after cooling. The material of the plastic inner bracket is PC. Using a plastic inner bracket made of PC enables the obtained hardware handle to have good performance in both high and low temperature impact tests and wear resistance tests, avoiding problems such as cracking in high and low temperature tests caused by too large a difference in thermal expansion coefficients in the existing solutions, and also avoiding the problem of unqualified wear resistance tests of ABS materials. Moreover, it can achieve the effects of reducing glue and shortening the injection molding cycle.

[0013] Furthermore, when there are appearance defects such as avoiding air streaks and whitening, marks on the high-gloss surface, and displacement and exposure of overmolded parts in the hardware handle, the position of the plastic inner bracket can be finely adjusted to ensure the appearance quality of the product. At the same time, a glue flow groove convenient for glue flow can be set in the plastic inner bracket, which is convenient for glue flow during the injection molding process and helps improve the yield of the product.

[0014] Furthermore, during the molding process of the hardware handle, an auxiliary shaping fixture is used to assist in shaping the hardware handle during the molding process, which can avoid problems such as unstable dimensional shrinkage and a large fluctuation range of the total length dimension of the product, ensure the quality of the product, and facilitate subsequent assembly.

[0015] In summary, the beneficial effects of this solution are as follows: Using a plastic inner bracket increases the yield of the product from 30% to approximately 80% when subjected to high and low temperature impact tests. Moreover, the surface appearance quality of the product is improved, the injection molding cooling time is reduced, the product cost is also reduced, and it is convenient to recycle the materials for defective products.

[0016] The above is only a preferred embodiment of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
