New Description: [New Technology Field] This creation is aimed at the molding die structure in the backlight unit. It is designed to provide a structure that can form two or more different molding materials without any other assembly parts or assembly structures. Forming mold structure. [Prior Art] In recent years, the development of liquid crystal displays has become more widely used and more fully functional with the integration of electronic components. However, the production of liquid crystal displays has become more complicated. . In general, liquid crystal displays can be classified into reflective liquid crystal displays, transmissive liquid crystal displays, or semi-reflective semi-transmissive liquid crystal displays. Generally, in a transmissive liquid crystal display and a transflective transflective liquid crystal display, a backlight module is installed on the back surface of the liquid crystal display, so as to provide a surface light source required for the liquid crystal display panel for display purposes. The assembly structure of the general backlight module is as shown in the first figure, and includes a light guide plate 1 1 , a frame 12 2 and a light source 13 . The light guide plate 11 and the frame 12 are respectively formed by injection molding, and in particular, the protrusions 1 1 1 are respectively designed on the two sides of the light guide plate 11 and the protrusions 1 are corresponding to the two sides of the frame 12 The 1 1 is provided with a fastening portion 1 2 1, which is used to assemble and position the light guide plate 1 1 and the frame 12 2 to each other. However, in order to assemble the light guide plate and the frame, the protruding portion designed on the side surface of the light guide plate can easily condense light there, thereby causing optical problems such as bright lines and vignetting angles, and in order to reduce weight and thickness. The trend is that the light guide plate and the frame in the backlight module must also be thinner and thinner. However, the thinning of the light guide plate and the frame will greatly reduce the assembly strength between the two, which will affect the structural strength of the product M307131 degrees 0 [ New content] In view of this, this creation is to provide a structure that can form two or more different raw materials, without the need for other assembled parts or a group structure. For the above purposes, the molding die of the creation can be divided into the movable mold side and the static mold, and the movable mold side is provided with two or more mold holes, and can form a movement, and is respectively connected to each mold cavity. There is an independent runner structure, each sprue structure is connected to =, and forms money π, and there are more than two molding cavity points in each cavity, and the movement of the pull side makes the respective cavities sequentially and respectively The shampoo structure corresponds to each other, and the different molding materials, such as the light guide plate forming raw materials and the frame forming material, can be injected into the same cavity to form the light guide. Structure to increase the assembly strength of the light guide plate and the frame. [Embodiment] The forming die structure of the light guide plate and the frame of the creative factory can be divided into a movable mold side and a static mold side, and the movable "seam puller is connected to the static mold side and is formed with a gate. On the upper molding cavity, the movement of the movable mold side causes the respective cavity A A 5 to have two corresponding structures, and the gate, the main A, / i sequence are not injected with the sprue junction. Forming the raw material 'to make each molding raw material 2', as shown in the second embodiment of the drawing, the forming mold forming a molding die 21' can be divided into the movable mold side 22 and the static mold side 23, in the form of M307131, pulling The first and second mold holes 2 4, 2 5 are provided in the inner portion 2, and the first and second mold wash structures are respectively connected in the first and second molds 8 24: 2 5 respectively. The first and second casting structures 2 Θ and 2 7 are connected to the static mold side 2 3 and are formed with first and second washing ports 28 and 29. The movable mold side 22 is provided with first and second mold cavities 24 and 25 And can form an f motion, the movable mold side 2 2 and is provided with an ejector structure 2 2 i, which can eject the finished product in the cavity.
