[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] Example 1

[0037] This embodiment relates to a mold structure, which can shorten the mold development cycle and reduce development costs, thereby facilitating adaptation to the rapid development needs of the market.

[0038] In terms of overall structure, Figure 1 and Figure 2 As shown, the mold structure of this embodiment includes an integrally formed fixed mold 10. Furthermore, the fixed mold 10 is formed with a base plate 11, a fixed mold plate disposed on the base plate 11, and a structural reinforcement 13 disposed between the fixed mold plate 10 and the base plate 11. Furthermore, the fixed mold plate 10 is provided with a molding surface 121 for forming the mold cavity, and a plurality of structural reinforcements 13 are arranged at intervals around the fixed mold plate 10.

[0039] At this time, as set above, the fixed mold 10 can be integrally formed to solve the problems of the fixed mold 10 plate in the traditional technology, such as long preparation cycle and roughing and stress relief cycle, and high development cost, so as to shorten the mold development cycle and reduce the mold production cost. At the same time, it can also effectively avoid the deficiency of weak mechanical strength of the fixed mold 10 based on the use of the structural reinforcement part 13, and ensure the structural strength of the mold structure, thereby meeting the market demand for short development cycle and low cost of new cars.

[0040] Based on the above overall introduction, in detail, in this embodiment, during specific implementation, the fixed mold 10 plate preferably has four side surfaces, and the number and arrangement of the structural reinforcement parts 13 can be set according to the actual structural reinforcement requirements of the fixed mold 10. For example, the four sides of the fixed mold 10 plate respectively have five reinforcement structural parts that are evenly spaced, etc., so that the fixed mold 10 as a whole has good structural strength.

[0041] It should be mentioned that the relevant structural parts not mentioned in the mold structure of this embodiment can refer to the fixed mold 10 structure or the various structures in the mold structure used for bumper molding well known to those skilled in the art, and will not be described in detail here.

[0042] Continue to see Figure 1As shown, in this embodiment, as a preferred implementation form, the structural reinforcement portion 13 includes a reinforcing rib provided between the bottom plate 11 and the fixed mold 10. It can be understood that the use of reinforcing ribs, and the reinforcing ribs provided between the bottom plate 11 and the fixed mold 10, makes the structure simpler, easier to manufacture, and achieves a cost-effective design.

[0043] At the same time, in this embodiment, as a preferred implementation form, see Figure 2 As shown, a hot runner connection port 111 is provided on the bottom plate 11, and a runner connecting the hot runner connection port 111 and the mold cavity is provided on the fixed mold plate 10 to ensure that the injection material remains in a molten state in the runner, thereby ensuring that the injection material can be smoothly injected into the mold cavity to form the desired injection molded product.

[0044] In specific implementation, in this embodiment, as a preferred implementation form, a plurality of avoidance grooves 112 are provided on the bottom of the base plate 11 (i.e., the side of the base plate 11 away from the fixed mold plate 12), and at least some of the avoidance grooves 112 are used to avoid hot runner components connected to the hot runner connection port 111. Providing multiple avoidance grooves 112 on the base plate 11 can achieve a weight-reducing design, which is conducive to improving the lightweight of the mold structure. At the same time, at least some of the avoidance grooves 112 are used to avoid hot runner components connected to the hot runner connection port 111, which can facilitate the layout and installation of the hot runner system.

[0045] Moreover, if necessary, according to the space occupied by the hot runner components and the actual weight reduction requirements of the fixed mold 10, at least part of the avoidance groove 112 can be extended through the bottom plate 11 toward the fixed mold plate 12 to enhance the avoidance effect and weight reduction effect of the avoidance groove 112.

[0046] Of course, the hot runner connection port 111 of this embodiment is preferably arranged at the bottom of the base plate 11 (that is, the side of the base plate 11 away from the fixed mold plate 12). At the same time, each avoidance groove 112 is also arranged at the bottom of the base plate 11, wherein at least part of the avoidance grooves 112 are arranged corresponding to the hot runner connection port 111, and the number and arrangement of the hot runner connection buckles can be set and adjusted according to the melting temperature requirements of the injection material of the fixed mold 10. For example, the hot runner connection port 111 is specifically four spaced apart at the bottom of the base plate 11, and the four hot runner connection ports 111 respectively correspond to an avoidance groove 112, etc.

[0047] In addition, in this embodiment, as a preferred implementation form, refer again to Figure 1 and Figure 2 As shown in , the bottom plate 11 is provided with a first weight-reducing hole 113 arranged through it, and the first weight-reducing hole 113 is arranged in a plurality of intervals around the fixed mold 10. This can help reduce weight and improve the lightweight of the mold structure.

[0048] In specific implementation, in this embodiment, four or six first weight-reducing holes 113 are provided on the bottom plate 11 at evenly spaced intervals corresponding to the four sides of the fixed mold 10, so as to achieve a relatively better weight-reducing effect without affecting the overall structural strength of the fixed mold 10. Of course, in addition to the above-mentioned setting, the number of the first weight-reducing holes 113 on the bottom plate 11 corresponding to the four sides of the fixed mold 10 can also be set and adjusted accordingly according to the actual weight-reducing requirements of the fixed mold 10, as long as it does not affect the structural performance of the fixed mold 10.

[0049] Furthermore, in this embodiment, as a preferred implementation form, multiple first weight-reducing holes 113 and multiple structural reinforcements 13 are staggeredly arranged along the direction surrounding the fixed mold plate 10. The main advantage of this arrangement is that it can achieve a lightweight design while ensuring that the mold structure has good structural strength.

[0050] In addition, in this embodiment, see Figure 1 As shown, as a preferred embodiment, the fixed mold 10 is provided with a parting surface 122 arranged around the edge of the molding surface 121 to facilitate the removal of the molded plastic part from the mold cavity.

[0051] In specific implementation, in this embodiment, as a preferred implementation, the fixed mold plate 10 is provided with a mating surface located outside the parting surface 122. The mating surface includes a positioning mating surface 123 for positioning the movable mold. Also, as a preferred implementation, the mating surface includes a guide mating surface 124 for guiding the movement of the movable mold. It will be appreciated that the coordinated use of positioning mating surface 123 and guide mating surface 124 helps ensure the quality of the molded plastic part.

[0052] In addition, see Figure 1 As shown, in this embodiment, as a preferred implementation form, at least part of the structural reinforcement portion 13 is provided with a second weight-reducing hole 131 , and at the same time, a hoisting portion 14 for hoisting the fixed mold 10 is also preferably provided on the bottom plate 11 .

[0053] This arrangement can further enhance the lightweighting of the mold structure by combining the second lightening holes 131 with the first lightening holes 113. Furthermore, the hoisting portion 14 can be utilized to facilitate the hoisting and use of the fixed mold 10. In a specific structure, as a preferred embodiment, each structural reinforcement portion 13 is provided with a second lightening hole 131. The size of the second lightening hole 131 can be determined so as not to affect the structural performance of the structural reinforcement portion 13.

[0054] Secondly, in this embodiment, in order to achieve further weight reduction effect, a third weight reduction hole can be set on the groove wall of the avoidance groove 112 when necessary, especially a third weight reduction hole can be set on the groove wall of two adjacent avoidance grooves 112. In this way, not only can the avoidance groove 112, the first weight reduction hole 113 and the second weight reduction hole 131 be combined to effectively improve the lightweight of the fixed mold 10, but it also has the effect of facilitating the arrangement and installation of hot runner components.

[0055] The mold structure of this embodiment allows the fixed mold 10 to be integrally formed, which can solve the problems of long preparation cycle and roughing and stress relief cycle and high development cost of the fixed mold 10 plate in traditional technology, thereby shortening the mold development cycle and reducing mold manufacturing costs. At the same time, the integrally formed structural reinforcement part 13 can also effectively avoid the problem of weak mechanical strength of the fixed mold 10, ensuring the structural strength of the mold structure, thereby meeting the market demand for short new car development cycle and low cost.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
