Description

Technical Field

[0001] The utility model relates to the technical field of mold cleaning, in particular to a mold cleaning device for a brake pad hot press. Background Art

[0002] A hot press is a device that heats two pre-fluxed and tinned parts to a temperature high enough to melt and flow the solder. After solidification, a permanent electrical and mechanical connection is formed between the parts and the solder. Depending on the product, the heating rate can be selected. The titanium alloy pressure head ensures uniform temperature, fast heating and long service life. The pressure head is specially designed with a horizontal adjustable design to ensure that the components are evenly pressed. Existing brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The insulation layer is composed of non-heat-conducting materials for the purpose of heat insulation. The friction block is composed of friction material and adhesive. When braking, it is squeezed on the brake disc or brake drum to generate friction, thereby achieving the purpose of vehicle deceleration and braking. In most cases, the brake pad manufacturing process is to put the evenly mixed friction material into a mold and press it into a friction pad through a hot press. However, in the process of brake pad manufacturing, whether the friction material and adhesive put into the mold are evenly distributed on the steel plate mold will directly affect the density of the pressed product, and whether the inside of the hot pressing hole is clean directly affects the distribution of the friction material on the mold. Uneven distribution of friction material often causes looseness or air holes in the pressed brake pad, and in more serious cases, it may directly lead to the scrapping of the brake pad. The patent number is CN213767347U, and its name is a brake pad hot press mold cleaning device. Although it can clean the mold table and hot pressing holes, the hot pressing raw materials cannot be cleaned out of the hot pressing holes. The newly added friction material will cause certain changes in the material quality and proportion in the hot pressing holes, thereby affecting the quality of the brake pads. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a mold cleaning device for a brake pad hot press.

[0004] According to the technical solution provided in the embodiment of the present application, a mold cleaning device for a brake pad hot press includes a mold table and a plurality of hot pressing holes arranged on the mold table. A mobile cleaning device is provided on the mold table. The mobile cleaning device realizes lateral movement through a lateral slide rail on the mold table and realizes longitudinal movement through a longitudinal slide rail on the lateral slide rail. The mobile cleaning device is connected to the longitudinal slide rail through a slider; the cleaning device on the mobile cleaning device moves up and down relative to the slider, and the cleaning brush on the cleaning device is connected to a dust extraction device, which extracts dust and materials cleaned by the cleaning brush.

[0005] Furthermore, the cleaning brush on the cleaning device is rotated in the horizontal direction through the transmission motor, so as to facilitate the cleaning of the material on the inner wall of the hot pressing hole.

[0006] Furthermore, the cleaning brush includes a brush shaft and bristles, the bristles are fixed to the lower end of the outer end surface of the brush shaft, the brush shaft is hollow inside, and the transmission gear on the transmission motor is meshed with the gear teeth on the outer end surface of the brush shaft.

[0007] Furthermore, the dust extraction device includes an exhaust fan and an exhaust pipe, the exhaust fan is connected to the cleaning brush through the exhaust pipe, and the exhaust pipe is fixedly inserted into the brush shaft through a bearing, so as to realize dust and material extraction while cleaning.

[0008] Furthermore, the exhaust pipe is a telescopic pipe, which ensures the connection between the dust extraction device and the cleaning device when the cleaning pipe moves up and down.

[0009] Furthermore, the transverse slide rail is placed in the groove on the end surface of the mold table, thereby reducing the influence of the mobile cleaning device arranged on the mold table on the hot pressing molding.

[0010] To sum up, the beneficial effects of the present application are as follows: the device of the present application connects the exhaust fan with the cleaning brush of the cleaning device. When the cleaning brush is working, the exhaust fan is turned on, so that the dust swept by the cleaning brush or the material adhering to the inner wall of the hot pressing hole can be drawn out of the hot pressing hole, and the hot pressing hole can be thoroughly cleaned, so that the quality and proportion of the material newly loaded into the hot pressing hole are uniform, and the production quality of the brake pad is prevented from being affected by hot pressing due to the material being retained in the hot pressing hole; at the same time, since the cleaning brush can move on the mold table through the horizontal slide rail and the longitudinal slide rail, and the cleaning brush can move up and down relative to the slider, the upper end surface and the hot pressing hole of the mold table can be automatically cleaned, the degree of automation is high, and the work efficiency is greatly improved.
