DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] like Figures 1 to 6 As shown, a demoulding device for a molded part with mirror attachment in an embodiment of the utility model comprises a sealing base 1, a quick clamping mechanism 2 and a movable mold insert 3.

[0035] By setting the sealing structure of the sealing base 1, the gas transported by the air inlet pipe 101 is not easily leaked, and thus the problem of being unable to blow out the mirror-attached molded part due to insufficient air pressure is not easily caused.

[0036] The sealing base 1 is connected to an air inlet pipe 101 for connecting to an air compressor to ensure that the gas pressure in the sealing base 1 is sufficient, so as to blow out the mirror-attached molded part in the attachment cavity 301 .

[0037] Preferably, for mirror-attached molded parts of different sizes and shapes, different demoulding forces may be required. Therefore, the air inlet pipe 101 can be connected to air compressors with different air pressure ranges to ensure that the mirror-attached molded parts can be blown out smoothly.

[0038] In addition, the sealing base 1 is provided with a plurality of air outlets 102, and the inside of the sealing base 1 is connected to the outside through the air outlets 102. The gas in the sealing base 1 is blown toward the mirror-attached molded part in the attachment cavity 301 through the air outlets 102 and the through holes 302, thereby achieving demoulding effect.

[0039] Specifically, a sealing groove is provided on the outside of the air outlet 102, and a sealing ring is installed in the sealing groove. When the top column 206 is fixed on the upper side of the mold movable insert 3, the top column 206 can fully squeeze the sealing ring between the sealing base 1 and the mold movable insert 3, so that the gas is not easy to leak from the gap between the sealing base 1 and the mold movable insert 3, thereby ensuring the stability of the air pressure.

[0040] like Figures 1 to 6 As shown, a plurality of control mechanisms are installed on the sealing base 1 , and the control mechanisms correspond to the air outlets 102 .

[0041] The control mechanism includes a valve 103 , which is installed in the sealing base 1 and corresponds to the gas outlet 102 . The valve 103 is used to control the gas flow of the gas outlet 102 .

[0042] In addition, a plurality of control switches 104 are installed on the sealing base 1, and the plurality of control switches 104 correspond to the plurality of valves 103 one by one. Different control switches 104 can control the opening and closing of the corresponding valves 103, thereby confirming the demoulding of the mirror-attached molded part at the specific air outlet 102 position.

[0043] Specifically, a control unit is installed in the sealing base 1, and the control unit is connected to a plurality of valves 103 and a plurality of control switches 104. When a worker operates the control switch 104, the control switch 104 feeds back instructions to the control unit, and the control unit can control the operation of the valve 103.

[0044] like Figures 1 to 6 As shown, a first bracket 105 is installed on the sealing base 1, and the first bracket 105 is used to fix the air pressure detection gauge 106.

[0045] Among them, an air pressure detection gauge 106 is installed on the first bracket 105, and the air pressure detection gauge 106 is installed on the air intake pipe 101. The air pressure detection gauge 106 is used to detect whether the air pressure of the flowing gas in the air intake pipe 101 is stable, that is, it is used to detect whether the air pressure of the gas delivered by the air compressor is stable, so as to ensure that the gas pressure in the sealing base 1 is sufficient.

[0046] Preferably, the detection range of the air pressure detection gauge 106 is larger than the output air pressure range of the air compressor.

[0047] like Figures 1 to 6 As shown, the quick clamping mechanism 2 is installed on the sealing base 1, and the quick clamping mechanism 2 is used to fix the movable insert 3 of the mold.

[0048] The quick clamping mechanism 2 includes a fixing seat 201 for mounting a second bracket 202 , and is used to clamp the mold movable insert 3 through the cooperation between the fixing seat 201 and the fixing block 207 , thereby fixing the mold movable insert 3 on the upper side of the sealing base 1 .

[0049] In addition, a second bracket 202 is installed on the fixed seat 201, and an auxiliary rod and a fixed rod 203 are hinged on the second bracket 202. A handle 204 is hinged between the auxiliary rod and the fixed rod 203. The staff operates the handle 204, and the handle 204 can operate the fixed rod 203 with the cooperation of the auxiliary rod.

[0050] Specifically, a pair of buckles 205 are engaged and connected on the fixing rod 203, and a top column 206 is connected between the pair of buckles 205. The top column 206 is arranged on the upper side of the mold movable insert 3, and a nut is threadedly connected on the top column 206. The top column 206 can be fixed on the fixing rod 203 through the cooperation between the buckle 205 and the nut. The top column 206 is used to fix the mold movable insert 3 on the upper surface of the sealing base 1, so that the mold movable insert 3 is not easily blown up by gas to cause gas leakage, so as to better blow out the mirror attached molded part in the attachment cavity 301.

[0051] like Figures 1 to 6 As shown, a fixing block 207 is installed on the sealing base 1 , a avoiding groove 209 is provided on the fixing seat 201 , and the mold movable insert 3 is fixed between the fixing block 207 and the avoiding groove 209 .

[0052] Among them, a positioning block 208 is installed on the sealing base 1, and the positioning block 208 is arranged between the fixing seat 201 and the fixing block 207. A positioning groove 303 matching the positioning block 208 is provided on the mold movable insert 3, so that the mold movable insert 3 is not easy to slide.

[0053] like Figures 1 to 6 As shown, the mold movable insert 3 is fixed on the sealing base 1 through a quick clamping mechanism 2.

[0054] The mold movable insert 3 is provided with an attachment cavity 301, and the attachment cavity 301 is used for molding a mirror-attached molded part.

[0055] In addition, the mold movable insert 3 is provided with a plurality of through holes 302, which respectively correspond to the plurality of gas outlets 102. The gas discharged from the gas outlets 102 is blown toward the mirror-attached molded part in the attachment cavity 301 through the through holes 302, and the mirror-attached molded part can be demoulded.

[0056] When in use, the mold movable insert 3 is fixed between the fixing seat 201 and the fixing block 207. At this time, the positioning block 208 is engaged in the positioning groove 303, and the plurality of through holes 302 correspond to the plurality of air outlets 102. The handle 204 is operated so that the top column 206 can fix the mold movable insert 3 on the upper surface of the sealing base 1. The sealing ring between the sealing base 1 and the mold movable insert 3 is fully squeezed to seal the gap between the sealing base 1 and the mold movable insert 3.

[0057] Connect the air inlet pipe 101 to the air compressor and run the air compressor. The air compressor delivers gas to the sealing base 1 through the air inlet pipe 101. The air outlet 102 can detect the stability of the gas pressure in the air inlet pipe 101, thereby ensuring that the gas pressure in the sealing base 1 is sufficient.

[0058] The corresponding valve 103 can be controlled by operating the control switch 104. When the valve 103 is opened, the gas in the sealing base 1 is discharged through the gas outlet 102, and blown to the mirror-attached molded part in the attachment cavity 301 through the through hole 302, breaking the mirror vacuum adsorption state generated by the mirror-attached molded part and the movable insert 3 of the mold, and the mirror-attached molded part can be blown out of the attachment cavity 301 to achieve the purpose of demolding.

[0059] The present application utilizes airflow to demold the mirror-attached molded parts, which effectively solves the problem that the mirror-attached molded parts are difficult to remove using conventional tools due to vacuum adsorption in the movable insert 3 of the mold, reduces the demolding time of the mirror-attached molded parts, and can reduce the probability of damaging the mirror-attached molded parts due to improper operation. At the same time, it can also reduce the probability of damaging the movable insert 3 of the mold using conventional tools, thereby reducing unnecessary economic losses for users and improving the processing rate of the mirror-attached molded parts.
