Embodiment 1

[0063] In the present embodiment, the concrete steps of processing method are:

[0064] Step 1. Assemble the upper mold 100, middle mold 200 and lower mold 300 of the forming mold and install them on the vulcanizing machine. Set the temperature of the vulcanizing machine between 160°C and preheat the forming mold. When the temperature of the forming mold reaches 160°C , put rubber into the injection cavity 210 of the middle mould, pressurize 15Mpa to close the mould, and then lock the molding mould.

[0065] Step 2: The rubber material fills the mold cavity and starts to vulcanize. The wire harness rubber protective cover 600 is formed on the mold core 430 in the mold cavity. After the vulcanization is completed, the vulcanizer is turned off. The vulcanization time is 5 minutes, and the vulcanization temperature is 160°C.

[0066]Step 3, detach the upper mold 100 and the middle mold 200 in sequence, and then drive the keel 420 to move relative to the bracket 410 to push the mo...

Embodiment 2

[0069] In this embodiment, the preheating temperature of step 1 is 167°C, the pressure of pressurized mold closing is 18Mpa, the vulcanization time in step 2 is 7min, and the vulcanization temperature is 165°C. The performance of the wire harness rubber protective sleeve 600 produced in this implementation The test shows that the average insertion force of the same batch of wire harness rubber protective sleeves 600 is 41.4N, and the average extraction force is 77.7N.

Embodiment 3

[0071] In this embodiment, the preheating temperature of step 1 is 170°C, the pressure of pressurized mold clamping is 20Mpa, the vulcanization time in step 2 is 10min, and the vulcanization temperature is 170°C. The performance of the wire harness rubber protective sleeve 600 produced in this implementation The test shows that the average insertion force of the same batch of wire harness rubber protective sleeves 600 is 42.4N, and the average extraction force is 78.3N.

[0072] The processing method of the present invention relies on the forming mold with a demoulding mechanism for processing, so that the rubber sheath can complete the demoulding of all the wire harness rubber protective sleeves 600 at one time after the vulcanization process, replacing the traditional manual one by one The demoulding method greatly shortens the overall processing time, improves the production efficiency, and reduces the manufacturing cost. At the same time, the prepared wire harness rubber pr...

Abstract

The invention discloses a forming mold and a processing method for a wire harness rubber protective cover, belonging to the field of rubber parts manufacturing equipment. The forming mold of the present invention includes an upper mold, a middle mold and a lower mold capable of forming a plurality of mold cavities by clamping, the lower mold is provided with a demoulding mechanism, the mold core of the mold cavity is connected to the keel, the vulcanization process is completed and the mold is opened Finally, the keel of the demoulding mechanism can move relative to the bracket to push the mold core in the mold cavity away from the mold cavity, and at the same time, the stripper on the keel can move relative to the keel to remove the wire harness rubber protection sleeve on the mold core , so only one operation can be used to remove the protective sleeves on multiple mold cores in batches. The operation is convenient and the efficiency is high, and the removed protective sleeves will not be damaged due to violent removal. The processing method of the invention has simple operation, high demoulding efficiency and processing efficiency of the wire harness rubber protective sleeve, and the prepared wire harness rubber protective sleeve has better performance.

Description

technical field [0001] The invention relates to the technical field of rubber parts manufacturing equipment, and more specifically, to a molding die and a processing method for a wire harness rubber protective cover. Background technique [0002] With the continuous development of artificial intelligence in the automotive industry, there are more and more requirements for the transmission of signals between devices, and these signals usually require wiring harnesses as transmission carriers. The automobile wiring harness is the continuous carrier of each component of the automobile. Its main function is to complete the transmission of electrical signals, while ensuring the reliability of the connecting circuit, supplying the specified current value to the electronic and electrical components, preventing electromagnetic interference to the surrounding circuits, and eliminating Electrical short circuit. [0003] Therefore, the selection of the wire harness rubber protective s...
