The present invention has the beneficial effects that: since direct injection molding is conducted by means of metal injection molding to obtain the golf panel according to the present invention, and the different thickness and bending design on the golf panel may be directly finished through the injection molding, which abandons the traditional manufacturing methods of metal sheet cutting, impact molding and CNC processing, and has few working procedures, and few subsequent processes. Therefore, the production efficiency is high and the production cost is greatly reduced. Moreover, the golf panel manufactured by the means of injection molding has the advantages of high product precision and fine surface, which greatly increases the product quality. Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustration purposes only and are not intended to limit the scope of the present disclosure in any way. The present invention is further described in detail hereinafter with reference to the drawings and the embodiment.
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.
A process of manufacturing a golf panel provided by the present invention comprises the following steps:
Step 1) Preparing materials, wherein a corresponding mould is manufactured according to appearance of a product, and proper injection materials are mixed according to the performance requirements of the product. The injection materials comprise various metal particles, adhesive, molding powder, catalyzer, etc., for example, the metal particles comprise magnesium hydrate, magnesium chloride and other magnesium compounds. To be specific, a designer uses 3D design software to design a 3D model according to the appearance of the product, then a construction drawing capable of being used for direct preparation and production is generated according to the designed 3D model, and a site constructor manufactures the mould according to the construction drawing. The mould comprises an injection system and a cavity. A material allocation personnel deploys the ratio of various materials according to the performances of the product to be manufactured, and tries to manufacture for many times to satisfy the performances of the product to be manufactured, so as to determine the ratio of the materials, and prepare the injection materials according to the ratio of materials determined.
Step 2) Injection molding, wherein the mixed materials are injected into the mould prepared according to step 1) by means of metal injection molding, so as to obtain a product workblank needed. To be specific, the cavity of the mould is uniformly greased before injection to facilitate demoulding, and make the mould be in an injectable status. Afterwards, the mixed injection materials are placed in a material heating barrel for heating, and since the injection material is fused by heating, a flowable injection fluid can be formed. Driven by a screw or a plunger, the injection fluid enters a mould cavity through a nozzle and an injection system of the mould, and the injection material is hardened and shaped in the cavity after a certain time to become the product workblank.
Step 3) Demoulding, which refers to demoulding and taking down the product workblank obtained in step 2) from the mould. After the injected material is formed into the product workblank, the product workblank is successively taken down from the mould without damage through a demoulding tool or under the condition without the assistance of the demoulding tool.
Step 4) Degreasing, which refers to degreasing the product workblank took down in step 3). Because the cavity in the mould is greased before injecting the fluid the product workblank can be adhered with grease after the product workblank is taken out. The product workblank is placed in a utensil for degreasing, a degreasant is placed in the utensil, and the degreasant in the utensil is heated to a temperature of 75° C. and then maintained for 30 min under that temperature, so as to better eliminate the grease adhered to the product workblank. After degreasing, the product workblank is taken out and dried.
Step 5) Sintering, which refers to sintering the degreased product workblank in step 4). After the product workblank is degreased and dried, the product workblank is further processed by using a sintering device. The product workblank is placed in the sintering device and heated to a temperature of about 560° C., and a catalyzer capable of promoting the generation of small particle size, large lattice constant and small microcrystal is added. The temperature of 560° C. is kept for about 1.5 h to obtain a polycrystal material, and cause cementation between the material particles in the product workblank, so as to increase the strength of the product workblank. Wherein, the polycrystal material comprises crystal, glass, air hole, etc.
Further, the product workblank is processed by the numerically-controlled machine tool after sintering, so as to obtain the golf panel 10 that is needed. In the process, a control module of the numerically-controlled machine tool is programmed, and then the numerically-controlled machine tool processes the product workblank according to the preset program. For example, multitasking manner is used in a cutter of the numerically-controlled machine tool through the set program, so as to eliminate the redundant filler according to an established motion trail, and process the product workblank into the golf panel 10 as shown in
