Description

Technical Field

[0001] This invention relates to the technical field of manufacturing equipment for car door sealing products, and more particularly to a core-pulling device and manufacturing method for corner molds of frameless hollow car door sealing products. Background Technology

[0002] Frameless door sealing products have a unique structure. Compared to ordinary car models, frameless door sealing products have higher requirements for appearance and waterproofing. The product involved in this invention has the following characteristics: a sealing strip with a bubble tube in the middle of the injection molded plastic serves as an insert. This insert sealing strip acts as a transition, forming a frameless door sealing product with a closed bubble tube area by the injection molding sealing strip, the injection molded plastic, and the insert sealing strip. The function of the bubble tube in this area is to seal and waterproof.

[0003] These types of products are difficult to produce. The mold needs to be designed according to the product structure and select a reasonable process opening position to ensure that the core can be effectively and non-destructively extracted from the sealed bubble tube area. However, the existing molds have the problem of difficult core extraction, which affects their production efficiency. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provides a corner mold core-pulling device and production method for frameless car door hollow sealing products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A core-pulling device for the corner mold of a frameless hollow door sealing product includes a base, a top plate on the base, lifting power source components installed on opposite side walls of the base, the lifting power source components connected to the side walls of the top plate via connecting components, a flip plate hinged to one side wall of the top plate, a flip handle on the flip plate, a fourth core component hinged to the flip plate, a third core component on one side of the fourth core component on the flip plate, a telescopic power source component on the top plate, a first product forming plate connected to the telescopic power source component, a second product forming plate fixed above the first product forming plate, a through groove through the top plate containing a third product forming plate, the bottom of the third product forming plate fixed to the base, an inlet sealing strip mounting groove on the first product forming plate, an insert sealing strip mounting seat on the flip plate, and a first core component and a second core component on the top plate. The first core component and the second core component correspond to the first opening of the product, the third core component corresponds to the second opening of the product, and the fourth core component corresponds to the third opening of the product.

[0007] The top surface of the top plate is provided with a patch injection area, and the patch injection area is provided with a first patch injection groove, a second patch injection groove and a third patch injection groove.

[0008] A method for producing a frameless hollow door seal product, utilizing the aforementioned corner mold core-pulling device for the frameless hollow door seal product, includes the following specific steps:

[0009] S1. Preparation work:

[0010] The lifting power source assembly raises the top plate and opens the flip plate. The insert sealing strip is installed on the insert sealing strip mounting seat of the flip plate. Then the flip plate is closed. The first core assembly is pushed into the bubble tube of the insert sealing strip. The lifting power source assembly is lowered to reset the top plate and contact the base. Then the second core assembly, the third core assembly, and the fourth core assembly are reset in sequence. Then the feed sealing strip is installed into the feed sealing strip mounting groove on the first product molding plate. After filling, injection molding can be prepared.

[0011] S2. Injection molding process:

[0012] The mold injects the product into the cavity, and also injects the first patch, second patch and third patch into the first patch injection groove, the second patch injection groove and the third patch injection groove;

[0013] S3, Core pulling and demolding:

[0014] S31. The lifting power source assembly lifts the top plate, separating the top plate from the base, and separating the third product forming plate on the base from the product.

[0015] S32, The telescopic power source assembly drives the first product forming plate and the second product forming plate to move backward to separate them from the product;

[0016] S33. Manually pull out the first core component inserted into the first opening of the product. After the first core component is pulled out, there is operating space. Then manually pull out the second core component inserted into the first opening of the product.

[0017] S34. Open the flip plate, and the flip plate will lift the product synchronously. At this time, manually pull out the third core component inserted into the second opening of the product. Then, rotate the fourth core component to increase the demolding gap between the product and other parts. Then demold the product from the fourth core component.

[0018] S4, Patch Repair

[0019] Remove the first patch, second patch, and third patch, and then bond them to the corresponding openings on the product.

[0020] The beneficial effects of this invention are: the invention addresses the reasonable process opening positions of the product design, ensuring that each core can be effectively and non-destructively extracted from the sealed area, and then develops corresponding "patches" that are pasted onto each opening position of the product, ensuring that the functional area of ​​the injection-molded product is a closed area; this invention has stability, high efficiency and ease of operation.
