[0031] Example

[0032] like Figure 1 The fixing plate 60 shown includes a head and a plate body. The plate body is wide and flat. Two round holes 601 are opened in the head and a strip groove 602 is opened between the head and the plate body.

[0033] Reference Figure 2 As shown, this utility model discloses a molding die for a fixed plate 60, including a panel 10, an upper moving die 20, a lower fixed die 30, an ejector plate 40, and a base 50 from top to bottom. The upper moving die 20 is fitted with an upper die core 201, and the lower fixed die 30 is fitted with a lower die core 301. The lower fixed die 30 has side molding blocks 302 on both sides of the lower die core 301. When the die is closed, the upper die core 201 and the lower die core 301 are closed, and the side molding blocks 302 are pressed against the closed sides formed by the upper die core 201 and the lower die core 301.

[0034] Reference Figure 3-6As shown, the upper mold core 201 has a first forming groove 2011 on both sides along the length direction, the lower mold core 301 has a second forming groove 3011 on both sides along the length direction, and the side forming block 302 has a number of T-shaped grooves 3021 on the end face near the lower mold core 301. The first forming groove 2011, the second forming groove 3011 and the T-shaped grooves 3021 close to form a cavity. Specifically, in this embodiment, the upper mold core 201 has four first forming grooves 2011 on each side, and the corresponding lower mold core 301 has four second forming side grooves on each side. When the mold is closed, the first forming grooves 2011 correspond one-to-one with the second forming grooves 3011, and the first forming grooves 2011 and the second forming grooves 3011 are interconnected. Then, the side forming blocks 302 are controlled to adhere tightly to the lower mold core 301, that is, the T-slots 3021 cover the first forming grooves 2011 and the second forming grooves 3011, forming vertically arranged side-by-side forming cavities on both sides. The vertical forming structure is combined with the traditional flat forming structure, which allows for the design of as many forming cavities as possible within the limited mold space. In this embodiment, eight fixing plates 60 are formed in one step, improving efficiency. The side forming blocks 302 have two bosses 3022 on the horizontal part of the T-slots 3021. The bosses 3022 are used to form the round holes 601 at the head of the fixing plates 60.

[0035] In addition, the side forming block 302 has two strip protrusions 3023 between the horizontal and vertical parts of the T-slot 3021. The strip protrusions 3023 are used to form the strip groove 602 between the head of the fixing plate 60 and the sheet body.

[0036] Reference Figure 8 As shown, the lower mold core 301 has a primary injection groove 303 and a secondary injection groove 3031. The primary injection groove 303 connects to the secondary injection groove 3031, and the secondary injection groove 3031 has at least two injection ports that connect to the second molding groove 3011. Specifically, when the mold is closed, hot melt adhesive enters the primary injection groove 303 from the injection port on the panel 10. The primary injection groove 303 connects to four secondary injection grooves 3031, and one secondary injection groove 3031 connects to two second molding grooves 3011. In this embodiment, each end of the secondary injection groove 3031 has two injection ports, and one second molding groove 3011 corresponds to two injection ports, thereby improving injection efficiency.

[0037] Reference Figure 7 As shown, several ejector pins 401 are provided on the ejector plate 40. The upper end of the ejector pins 401 is flat and can slide upward through the lower fixed mold 30. The lower mold core 301 is placed at the bottom of the second forming groove 3011. Specifically, when the mold opens, the forming blocks 302 on both sides and the upper mold core 201 leave the lower mold core 301, the product falls into the lower mold core 301, and then the ejector plate 40 pushes the ejector pins 401 to push the product out of the lower mold core 301. The flat ejector pins 401 are designed to fit the structure of the narrow head of the fixed plate.

[0038] Furthermore, a positioning groove is provided at the bottom of the side forming block 302, and the lower fixed mold 30 is provided with elastic positioning protrusions on both sides of the lower mold core 301. When the mold is closed, the side forming block 302 is close to the lower mold core 301, and the elastic positioning protrusions are placed in the positioning groove, which plays the role of positioning the side forming block 302.
