In one embodiment, referring to fig. 1 to 3, a base bracket 10 for a television includes an injection molding frame 110 and an injection molding housing 120; the injection molding framework 110 comprises a supporting top seat 111 and two fixing foot seats 112, wherein a front mold positioning protrusion structure 1112 is arranged at the top of the supporting top seat 111, the two fixing foot seats 112 are respectively arranged at the left end and the right end of the supporting top seat 111, and a rear mold positioning protrusion structure 1121 is arranged at the bottom of each fixing foot seat 112; the injection molding housing 120 includes a top seat housing 121 and two foot seat housings 122, the top seat housing 121 covers the supporting top seat 111, an upper groove structure 1212 for the front mold positioning protrusion structure 1112 to penetrate through is disposed at the top of the top seat housing 121, the two foot seat housings 122 are respectively disposed at the left end and the right end of the top seat housing 121, each foot seat housing 122 covers each fixed foot seat 112, and a lower groove structure 1221 for the rear mold positioning protrusion structure 1121 to penetrate through is disposed at the bottom of each foot seat housing 122.
It should be noted that the base bracket 10 is a two-shot injection molding structure, the first shot injection molding structure is an injection molding framework 110, and the second shot injection molding structure is an injection molding housing 120; the injection molding process comprises the following steps: firstly, injection molding is carried out to form an injection molding framework 110, then the injection molding framework 110 is placed in a mold for injection molding to form an injection molding shell 120, the mold comprises a front mold and a rear mold, and a front mold positioning protruding structure 1112 is arranged on a supporting top seat 111 of the injection molding framework 110 and used for positioning a groove structure corresponding to the front mold; a rear mold positioning protruding structure 1121 is arranged on the fixing foot base 112 of the injection molding framework 110 and is used for positioning a groove structure corresponding to the rear mold; thereby realizing the positioning of the injection molding framework 110 in the injection molding shell 120 mold, and then performing the second injection molding to form the injection molding shell 120. Thus, the injection molding cycle of the base bracket 10 can be shortened, the injection molding cost is reduced, and the injection molding efficiency is improved; the injection molding framework 110 is used for improving the strength of the base support 10 and improving the weight supporting effect of the base support 10; the injection molding housing 120 is used for covering the injection molding frame 110, and can improve the appearance, thickness and waterproofness of the base support 10, thereby improving the quality of the base support 10.
In the injection molding process, the injection molding material can seriously affect the quality of the injection molded product. For example, a suitable melting point injection molding material is selected to ensure that the injection molding framework 110 does not generate flow marks due to high temperature in the second injection molding; if a material with too low rigidity is selected, the strength of the product is insufficient; if a material with too good rigidity is selected, the toughness of the product is insufficient, and the product is easy to break; through repeated theoretical and practical deduction, the following steps are finally determined: when the injection molding material of the injection molding framework 110 is PC plastic and the injection molding material of the injection molding housing 120 is PC plastic or ABS plastic, it can be ensured that the injection molding framework 110 does not generate flow marks due to high temperature during the second injection molding, and the base bracket 10 can have better processability and strength. Therefore, the injection molding framework 110 is a PC injection molding framework 110, and the injection molding housing 120 is a PC injection molding housing 120 or an ABS injection molding housing 120.
Further, the top of the supporting top seat 111 protrudes upwards to form a supporting boss 1111, the top of the top seat casing 121 protrudes upwards to form a boss casing 1211, and the boss casing 1211 covers the supporting boss 1111.
Further, the front mold positioning protrusion structure 1112 includes a plurality of square positioning blocks 1112a, and the plurality of square positioning blocks 1112a are respectively disposed at the periphery of the top of the supporting boss 1111. For example, the front mold positioning protrusion structure 1112 includes four square positioning blocks 1112a, and the four square positioning blocks 1112a are respectively disposed at four corners of the top of the supporting boss 1111. Accordingly, the upper groove structure 1212 is a square groove. Further, each rear mold positioning protrusion structure 1121 includes an inclined top positioning block 1121a and an arc-shaped positioning block 1121b, the inclined top positioning block 1121a is disposed at a peripheral position of the bottom of the fixed foot base 112, and the arc-shaped positioning block 1121b is disposed at a terminal end of the bottom of the fixed foot base 112. Accordingly, the lower groove structure 1221 is a pitched roof groove 1221a and an arc groove 1221 b. For example, the inclined top positioning block 1121a is provided in plurality, and the inclined top positioning blocks 1121a are disposed at intervals at the peripheral position of the bottom of the fixed foot base 112. In another example, the number of the inclined top positioning blocks 1121a is four.
Therefore, the square positioning block 1112a is arranged on the supporting top seat 111, and the inclined top positioning block 1121a and the arc positioning block 1121b are arranged on the fixing foot seat 112, so that the positioning effect of the injection molding framework 110 in the injection molding shell 120 mold can be improved, and the phenomenon that the placing position is wrong or the injection molding process is displaced is avoided.
Further, a fool-proof post 1213 is disposed at the center of the top of the boss casing 1211, and the fool-proof post 1213 is used for positioning and connecting with a corresponding groove structure of the television, so as to guide the installation of the base bracket 10 on the television.
Further, a first screw through hole 1113 is formed at one side of the fool-proof post 1213 on the top of the supporting boss 1111, and a second screw through hole 1214 is formed at a position corresponding to the first screw through hole 1113 on the top of the boss housing 1211. It should be noted that, corresponding screw through holes are formed in the television, and the second screw through hole 1214, the first screw through hole 1113, and the screw through hole of the television are sequentially inserted and locked through the tail portion of the bolt, so that the base bracket 10 can be firmly connected with the television. The bottom of the first screw through hole 1113 is outwardly formed with a first clearance groove 1114, and the bottom of the second screw through hole 1214 is outwardly formed with a second clearance groove 1215, which together conceal the head of the receiving bolt.
