Description

Technical Field

[0001] This utility model relates to the field of film mold technology, specifically to a dual-core interchangeable film mold. Background Technology

[0002] Diaphragm-type products are used in automotive vacuum boosters, located in the engine compartment in front of the brake pedal. The pedal pushrod is connected to the brake pedal lever, and the rear end is bolted to the brake master cylinder. The pushrod at the center of the vacuum booster rests on the first piston rod of the brake master cylinder. Therefore, the vacuum booster assists in the braking process between the brake pedal and the brake master cylinder. It primarily works by creating a pressure difference between the booster's internal environment and the external air through the pedal, which then applies force to the brake master cylinder via the pushrod, helping the car achieve braking quickly. Diaphragm failure results in a lack of pressure difference between the booster's internal and external environments, leading to brake failure and compromising driving safety. While diaphragm-type products have some versatility, the diaphragm molds are difficult to modify. For new boosters with low production volumes, two sets of molds are often required for simultaneous development, resulting in wasted mold resources and increased costs.

[0003] The front and rear membranes are identical except that the front membrane has a through hole and the rear membrane does not. However, since the membrane is a single-cavity mold with a complex structure, developing one set of positive air boosters requires developing two sets of molds, which is costly, has low utilization, and is not competitive in the market. Utility Model Content

[0004] The purpose of this invention is to provide a dual-core interchangeable film mold, which solves the technical problems of mold resource waste and increased cost.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A dual-core interchangeable mold includes an upper plate and a lower plate. An upper template is fixedly installed on the lower end of the upper plate by a plurality of upper fastening bolts. A lower template that mates with the upper template is fixedly installed on the upper end of the lower plate by a plurality of lower fastening bolts. A processing mold core is detachably installed on the upper template, and a mold core groove that mates with the processing mold core is provided on the lower template.

[0007] Preferably, both the upper and lower pads are provided with stepped holes for installing fastening bolts, and the depth of the stepped holes is greater than the height of the bolt head.

[0008] Preferably, a support column is provided between the upper pad and the lower pad.

[0009] Preferably, a guide post is fixedly provided at the lower end of the upper pad, and a guide hole that cooperates with the guide post is provided on the lower pad.

[0010] Preferably, a sealing groove is provided between the upper and lower templates when they are sealed together.

[0011] Preferably, the upper template is provided with stepped screw holes, and mounting bolts for installing the processing mold core are threaded onto the stepped screw holes.

[0012] Preferably, a sealing ring is fitted around the outer periphery of the mounting bolt, and the sealing ring is in a sealed fit with the bottom of the stepped bolt hole groove.

[0013] Preferably, the installation mode of the processing mold core includes through-mounting and non-through-mounting.

[0014] Preferably, when the processing mold core is installed through, the lower end of the upper template is provided with a mold core flange that cooperates with the processing mold core, and the mold core flange is provided with a limiting buckle that fits against the outer periphery of the processing mold core.

[0015] Preferably, when the processing mold core is non-through-mounted, the lower end of the upper template is provided with a mold core flange that mates with the processing mold core, and the mold core flange is provided with a mold core sealing plate for sealing the processing mold core.

[0016] The beneficial effects of this utility model are as follows: Compared with the old-fashioned mold, the innovative double-core interchangeable mold has greatly improved the processing efficiency. The CNC milling workload at the mold core is reduced, and the double-core interchangeability avoids the need to open a new mold, saving time and costs. In addition, the mold core is a vulnerable part, and the interchangeable mold structure extends the service life of the mold. At the same time, through double-core interchangeability, one set of molds can produce two different products. Attached Figure Description
