Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 2 As shown, a mold mechanism for automatic demoulding after ejection includes a bottom plate 1, a movable template 2, a fixed template 3 and an injection molding plate 4 in turn. The injection molding plate 4 has an injection port 41, and the movable template 2 has two A core 21 that protrudes from the surface of the movable template 2, the fixed template 3 has a first cavity 31 and a second cavity 32 that are sunken inside the fixed template 3, and the size of the first cavity 31 is smaller than that of the second cavity 32, the first cavity 31 and the second cavity 32 cooperate with a core 21 to form the first forming cavity 5 and the second forming cavity 6, preferably, the first cavity 31 and the second cavity The cavity 32 is arranged symmetrically along the axis line of the movable template 2, and the two...

Abstract

The invention belongs to the technical field of automobile supplies, in particular to a mold mechanism with popup after ejection in automatic demoulding. The mold mechanism with popup after ejection in automatic demoulding comprises a base plate, a movable mold plate, a fixed mold plate and an injection molding plate. The movable mold plate is provided with two mold cores protruding out of the surface of the movable mold plate. The fixed mold plate is provided with a first mold cavity and a second mold cavity. The first mold cavity and the second mold cavity concave towards the interior of thefixed mold plate. The first mold cavity and one mold core are used in cooperation to form a first forming cavity. The second mold cavity and the other mold core are used in cooperation to form a second forming cavity. The first forming cavity communicates with an injection molding port through an injection molding flow pass arranged in the fixed mold plate. The first forming cavity communicates with the injection molding port through an injection molding flow pass arranged in the fixed mold plate. With the mold mechanism with popup after ejection in automatic demoulding, multiple parts of anautomobile handle support can be formed integrally, the later assembly difficulty is reduced, the time consumed for assembly is shortened, and the combination strength of a product is guaranteed; andbecause of the design that the mold mechanism is provided with a slingshot ejector pin, the problem that because demoulding travel is not enough, film drawing is prone to happening according to a traditional ejection manner is solved, the product quality is guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile supplies, and in particular relates to a mold mechanism for ejecting and automatically ejecting from the mold. Background technique [0002] The traditional four-door handle of a car is assembled with multiple parts such as door panel, sheet metal, handle cover, etc., but the assembly tolerance of multiple products needs to be taken into account during assembly, which makes the assembly process complicated, product surface difference, gap control Not ideal, which does not meet the increasing and strict appearance requirements of car users. [0003] For example, a Chinese invention patent discloses a combined automobile door handle molding die [Application No.: 201420643490.2]. Plate, strong tie rod, secondary ejection mechanism, the floating plate is located under the top plate, the lower mold core is fixed in the lower formwork, the inclined top is inserted into the lower mold core from botto...
