Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing pad processing equipment, in particular to a processing mould for an automobile shock-absorbing pad. Background Art

[0002] The main function of automobile shock absorbers is to reduce noise and vibration during vehicle driving and improve passenger comfort. Automobile shock absorbers are mainly rubber products. When producing rubber shock absorbers on automobiles, they are basically made of one-piece injection molding. Two molds that are compatible with the rubber pads are used, and the injection molding solution is poured between the two molds for solidification and molding.

[0003] In order to improve the efficiency of processing automobile shock absorber pads, the prior art has made many improvements to automobile shock absorber pad processing molds, such as the patent with patent announcement number CN220180003U, which discloses an automobile shock absorber pad processing mold, including a placement plate, a placement groove is provided on the top of the placement plate, and the first and second molds that match each other are slidably installed at both ends of the inner bottom of the placement groove, and the bottoms of the first and second molds are provided with mutually matching fixed grooves, and a heat sink is installed at the middle end of the inner bottom of the placement groove, and the two ends of the heat sink are respectively located in the two fixed grooves, and the two ends of the top of the placement plate are slidably installed with a movable plate. The utility model heat sink can quickly dissipate the solution injected inside it through the first and second molds, so that the injection molding solution of the shock absorber pad can be quickly solidified, and the mold processing efficiency of the shock absorber pad can be improved when used.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative document, the first mold and the second mold are closed, and the injection molding solution is filled in the closed first mold and the second mold. After the injection molding solution in the first mold and the second mold is formed, the first mold and the second mold are moved in opposite directions. In actual operation, since the outer side surface of the molded shock-absorbing pad is tightly against the inner side walls of the first mold and the second mold, the first mold and the second mold can be separated from the shock-absorbing pad at the same time only when the friction between the inner side walls of the first mold and the second mold and the outer side surface of the shock-absorbing pad is the same. When the friction between the inner side walls of the first mold and the second mold and the outer side surface of the shock-absorbing pad after molding is different, the molded shock-absorbing pad can only be demolded from one mold, and the molded shock-absorbing pad will be stuck in the mold where the friction between its outer side and the inner side wall of the mold is large. Therefore, it is necessary to manually remove the molded shock-absorbing pad, which reduces the production efficiency of the automobile shock-absorbing pad. Therefore, there is an urgent need in this field to improve the automobile shock-absorbing pad processing mold to solve the defects of the prior art. Utility Model Content

When the push-out plate 6 is located in the placement groove 7, one side of the push-out plate 6 is flush with the inner side wall of the mold body 1 and the push-out plate 6 is in a sealed state with the placement groove 7, and each mold body 1 is provided with an elastic feeding pipe 18 on the upper side, and a heat dissipation plate 17 matched with the two mold bodies 1 is provided on the bearing platform 2, and a sealing ring 19 is embedded between the two mold bodies 1. The cross section of the push-out plate 6 is T-shaped, and the placement groove 7 is matched with the push-out plate 6.

[0029] Specific implementation method in this embodiment: when the automobile shock absorber pad is injection molded, the two mold bodies 1 are driven to move toward each other by the driving unit 3, the two mold bodies 1 are molded together and the sealing ring 19 is squeezed to improve the sealing effect of the two mold bodies 1 after the mold is closed. At this time, the ejection plate 6 is located in the placement groove 7, and one side of the ejection plate 6 is flush with the inner wall of the mold body 1, the ejection plate 6 and the placement groove 7 are in a sealed state, the injection molding solution is injected into the two mold bodies 1 through the feeding pipe 18, and after the injection molding solution is molded, the two mold bodies 1 are cooled by the heat dissipation plate 17, and the two mold bodies 1 are driven to move back to each other by the driving unit 3 at the same time. When the two mold bodies 1 move, the fixed rod 5 will not move with the mold body 1, and several ejection plates 6 limit the position of the shock absorber pad after molding, and the two mold bodies 1 slide along the fixed rod 5, so that the molded shock absorber pad is separated from the two mold bodies 1 at the same time, thereby improving the efficiency of the production and processing of the automobile shock absorber pad, and by setting the ejection plate 6 to have a T-shaped cross-section, the placement groove 7 is adapted to the ejection plate 6, and the sealing of the ejection plate 6 after being located in the placement groove 7 is improved.

[0030] Embodiment 2

[0031] See also Figure 1 , Figure 2 and Figure 4 This embodiment includes the above-mentioned embodiment, wherein the driving unit 3 includes a driving motor 8 fixedly installed at one end of the supporting platform 2, sliders 9 are fixedly installed on the lower sides of the two mold bodies 1, a slide groove 10 adapted to the slider 9 is opened on the supporting platform 2, and a bidirectional screw rod 11 is rotatably connected in the slide groove 10, the bidirectional screw rod 11 passes through the slider 9 and is threadedly connected to the slider 9, and one end of the bidirectional screw rod 11 passes through the supporting platform 2 and is fixedly installed at the output end of the driving motor 8.

[0032] The specific implementation method in this embodiment is as follows: when the two mold bodies 1 need to be moved toward or away from each other, the drive motor 8 is started, and the output end of the drive motor 8 drives the bidirectional screw rod 11 to rotate. The thread teeth on the side of the bidirectional screw rod 11 are symmetrical and in opposite directions. When the bidirectional screw rod 11 rotates, it will drive the two sliders 9 to move toward or away from each other in the slide groove 10, and the corresponding sliders 9 drive the mold body 1 to move on the supporting platform 2.

[0033] Among them, the above-mentioned drive motor 8 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The drive motor 8 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0034] Implementation Three

[0035] See also Figure 3, this embodiment includes all the above embodiments, which further includes: the end of the fixing rod 5 away from the mold body 1 passes through the bearing column 4, the end of the fixing rod 5 away from the mold body 1 is fixedly connected with a stopper 12, a spring 13 arranged on the side of the fixing rod 5 is fixedly connected between one side of the stopper 12 and the side of the bearing column 4, a limiting block 14 is fixedly connected to one side of the ejection plate 6 close to the fixing rod 5, a limiting groove adapted to the limiting block 14 is opened at one end of the fixing rod 5 close to the ejection plate 6, and a fixing bolt 15 with one end threadedly connected to the limiting block 14 passes through the stopper 12 and the fixing rod 5.

[0036] Specific implementation method in this embodiment: the spring 13 has a pulling force on the stopper 12 in the direction of the mold body 1. When the mold body 1 moves, due to the friction between the side of the molded shock-absorbing pad and the inner wall of the mold body 1, a certain resistance will be generated when the mold body 1 moves. When the friction between the inner wall of the mold body 1 and the side of the shock-absorbing pad after molding is large, suddenly extruding the molded shock-absorbing pad out of the mold body 1 will cause damage to the side of the shock-absorbing pad. The spring 13 is stretched and its pulling force on the stopper 12 is gradually increased, and the shock-absorbing pad is slowly extruded out of the mold body 1 to avoid damage to the appearance of the molded shock-absorbing pad. By setting a polygonal limit block 14 and a fixing bolt 15, it is convenient to assemble the push-out plate 6 and the fixing rod 5. The limit block 14 is inserted into the limit groove at one end of the fixing rod 5, and one end of the fixing bolt 15 passes through the stopper 12 and the fixing rod 5 and is threadedly connected to the limit block 14, and the fixing bolt 15 is tightened.
