[0002] Existing mold structures for manufacturing automotive seal molds consist of a single extruded die plate and splitter plate, such as figure 1 , figure 2 As shown, the core is fixed on the manifold with U-shaped brackets, such as image 3 As shown, after the core passes through the splitter plate, the product is produced through the extrusion mold; the mold of this design has only one outlet plate, and the glue output of the core is limited by the glue outlet and outlet when the mold is out. Due to the influence of glue speed, it is difficult for the molded products to meet the product requirements, and it is difficult to adjust the designed and processed molded boards online according to the actual molded results.

Embodiment
[0017] This example is Figure 4-Figure 8 As shown, it includes the extrusion die manifold, the extrusion die plate and the extrusion die equalizing plate designed with the extrusion die plate: the extrusion die manifold is equipped with a core (usually rubber material) Through the conical hole, there is an outlet hole for the corresponding product in the middle of the extrusion die plate, and the corresponding position of the extrusion die pressure plate is provided with a protrusion that matches the exit hole. In the working state, the extrusion die pressure plate and extrusion The molded die plate is assembled and matched, the protrusion is located in the die hole, and the gap between the protrusion and the die hole forms a cavity, and the protrusions and the periphery of the protrusion of the extrusion die equalizing plate are reserved for multiple glue outlets that can be adjusted in real time according to the actual die structure. Port 1, in the initial state, process th...

The invention discloses a mold structure of an automobile sealing element. The mold structure of the automobile sealing element is characterized in that an extrusion mold flow-dividing plate, an extrusion mold extruded plate and an extrusion mold pressure-equalizing plate matched with the extrusion mold extruded plate are included, a conical hole for a mold core to penetrate through is formed in the extrusion mold flow-dividing plate, an extruded hole corresponding to a product is formed in the middle of the extrusion mold extruded plate, a protrusion matched with the extruded hole is arrangedat the corresponding position of the extrusion mold pressure-equalizing plate, the extrusion mold pressure-equalizing plate and the extrusion mold extruded plate are in assembling fit with each otherin the working state, the protrusion is located in the extruded hole, a cavity is formed in a gap between the protrusion and the extruded hole, and a plurality of glue outlets for adjusting the glueoutlet amount are formed in the protrusion of the extrusion mold pressure-equalizing plate and the periphery of the protrusion.
Description
technical field [0001] The invention relates to a mold structure for an automobile seal, belonging to the technical field of mold manufacturing for an automobile seal. Background technique [0002] Existing mold structures for manufacturing automotive seal molds consist of a single extruded die plate and splitter plate, such as figure 1 , figure 2 As shown, the core is fixed on the manifold with U-shaped brackets, such as image 3 As shown, after the core passes through the splitter plate, the product is produced through the extrusion mold; the mold of this design has only one outlet plate, and the glue output of the core is affected by the glue outlet and outlet when the mold is out. Due to the influence of glue speed, it is difficult for the molded products to meet the product requirements, and it is difficult to adjust the designed and processed molded boards online according to the actual molded results. Tooling costs and commissioning costs. Contents of the invent...
