Description

Technical Field

[0001] The utility model relates to the field of mold processing, in particular to an automobile part mold with a dustproof function. Background Art

[0002] Auto parts molds are tools or equipment used to manufacture auto parts. These molds are usually made of metal or plastic and are designed and manufactured according to the required part shape and size. Auto parts molds can include die-casting molds, injection molds, and stamping molds. They are used to manufacture various auto parts including body structures, engine parts, and interior components.

[0003] After searching, Chinese patent announcement number: CN213495375U discloses an automobile part mold with dustproof function. The device first drives the first motor through the incomplete worm, thereby driving the rotating shaft to rotate, so that the first fan blade rotates, and then drives the second motor to rotate the incomplete worm, thereby driving the worm wheel and the bevel gear to rotate synchronously. The rotation of the worm wheel causes the traction rope and the spring to deform, so that the rotating box rotates in a reciprocating arc direction, so that the first fan blade rotates in the same arc, thereby increasing the range of heat dissipation and dust removal.

[0004] However, in actual use, since the lower mold is often in direct contact with the outside air before contacting the upper mold, it is impossible to achieve the effect of dust-proof treatment inside the mold by only accelerating the air flow speed in this area through a fan. At the same time, due to the accelerated air flow speed, the external dust will also re-attach to the lower mold due to movement. Therefore, an automotive parts mold with dust-proof function is proposed to solve the above problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 2The utility model provides an embodiment: an automobile part mold with dustproof function, comprising a support frame 1, a top plate 5 is fixedly connected to the upper end of the support frame 1, a placement frame 4 is fixedly connected to the upper surface of the support frame 1, a vacuum dust removal device 2 is arranged on the inner side of the support frame 1, an injection head 6 is contacted at the center of the inner surface of the top plate 5, and a dust blocking device 3 is arranged at the lower end of the inner surface of the injection head 6;

[0033] The vacuum dust removal device 2 includes an upper mold 201, a bellows 203 is fixedly connected to the lower surface of the upper mold 201, an insertion rod 204 is fixedly connected to the lower surface of the bellows 203, an air nozzle 202 is fixedly connected to the inner surface of the upper mold 201, and the air nozzle 202 is connected to a filter tank 205 through a hose.

[0034] A sliding rod is provided at the upper end of the support frame 1, so that the upper mold 201 can slide inside the support frame 1. A through hole is provided at the center of the inner surface of the top plate 5, so that the injection head 6 can be accommodated here. The interior of the placement frame 4 is hollow, and people are used to place the lower mold here. The upper end of the injection head 6 is connected to a feed pipe, so that raw materials can be transported through the pipeline. A cylindrical groove is provided on the upper surface of the placement frame 4, so that the bellows 203 can drive the insertion rod 204 to insert into the upper end of the placement frame 4 during the descent process, thereby avoiding the bellows 203 from being deformed due to changes in air pressure when the vacuum pump sucks out air. , a plurality of through holes are provided at the center of the inner surface of the upper mold 201, so that it can slide inside the support frame 1, and the air nozzle 202 can also pass through it. The diameter of the insertion rod 204 is the same as the inner diameter of the through hole provided on the upper surface of the placement frame 4, so that the insertion rod 204 can be fully inserted into the placement frame 4, and the air nozzle 202 passes through the upper mold 201. A through hole is provided at the upper end of the filter tank 205, so that the air between the upper mold 201 and the placement frame 4 can enter the filter tank 205 and be discharged from the filter tank 205 after being filtered. A through hole is provided at the lower end of the outer arc surface of the filter tank 205.

[0035] Reference Figure 1 , Figure 3 as well as Figure 4 The dust blocking device 3 includes a discharge port 301, a baffle 302 is fixedly connected to the lower end of the inner surface of the discharge port 301, an inner rod 305 is fixedly connected to the center of the inner surface of the baffle 302, a sealing block 304 is rotatably connected to the outer arc surface of the inner rod 305, and a limiting block 303 is fixedly connected to the front end of the baffle 302.

[0036] The upper end of the discharge port 301 is fixedly connected with the injection head 6, and a through hole is provided at the lower end of the discharge port 301, so that the material can flow out from it. The inner surface of the baffle 302 is provided with a rectangular groove, so that the sealing block 304 can be accommodated here. The outer arc surface of the inner rod 305 is elastically connected to the sealing block 304 through a spiral spring. Therefore, when the injection pressure at the upper end becomes smaller, the spiral spring can drive the sealing block 304 to rotate through its own elastic force. The rear end of the sealing block 304 is provided with a through hole, so that it can form a rotational connection with the inner rod 305. The end of the sealing block 304 close to the limit block 303 is set as an arc surface, so that it will not cause motion interference with the discharge port 301 during rotation, and the limit block 303 is set as an arc as a whole.

[0037] Working principle: When the device is in use, the upper mold 201 needs to be driven downward as a whole by an external driving device. At this time, the bellows 203 will move downward accordingly and insert the insertion rod 204 below it into the groove above the placement rack 4, thereby positioning the lower end of the bellows 203. At the same time, the bellows 203 will be squeezed to seal the area above the placement rack 4. At the same time, the vacuum pump needs to be connected to the filter tank 205, so that the vacuum pump can continuously extract the air and dust in the area between the placement rack 4 and the upper mold 201 through the hose and the air nozzle 202, and filter it through the filter tank 205. At the same time, the vacuum area can also reduce the amount of bubbles inside the mold during the injection process of the injection head 6.

[0038] In addition, during the injection process of the present device, since the discharge pressure on the inner side of the injection head 6 is relatively large, the sealing block 304 will be squeezed and rotated downward, thereby completing the normal discharge process. After the discharge is completed, since the discharge pressure on the inner side of the injection head 6 is relatively small, the volute spring will drive the sealing block 304 to rotate in the direction of the limit block 303 through its own elastic force, and enable the lower end of the discharge port 301 to be sealed by the sealing block 304, thereby reducing the possibility of external dust entering the lower end of the injection head 6, thereby reducing the possibility of raw materials being contaminated during the injection process.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
