[0037] A scraping gear 127 is fixedly mounted on the upper end of the scraping shaft 123. Teeth are evenly arranged on three-fifths of the circumference of the adjustment circular plate 122. When the teeth on the adjustment circular plate 122 and the scraping gear 127 are meshed, a gear pair is formed. An auxiliary gear 134 is rotatably mounted on the support frame 102.

At this time, the demoulding push plate 116 moves to the position closest to the lower bottom plate 104, that is, the demoulding push plate 116 cannot move further, and then the T-shaped slide plate 129 cannot move further, and the strip slide plate 130 moves upward relative to the T-shaped slide plate 129, and the strip slide plate 130 and the T-shaped slide plate 129 are moved upward. 9 is compressed, and the auxiliary rack 131 contacts the auxiliary gear 134, causing the auxiliary gear 134 to rotate. Under the action of bevel gear 132 and bevel gear 2 133, the adjusting circular plate 122 rotates, and the torsion spring between the adjusting circular plate 122 and the support frame 102 is compressed. Under the action of the torsion spring between the T-shaped rotating plate 111 and the adjusting circular plate 122, the T-shaped rotating plate 111 rotates synchronously, and finally the T-shaped rotating plate 111 rotates 90 degrees to contact the scraping gear 127. At this time, the T-shaped rotating plate 111 is located directly above the upper base plate 103, and the positions of the cleaning push rods 114 on the T-shaped rotating plate 111 correspond to the positions of the through holes on the upper base plate 103 one by one.

[0040] At this time, the teeth on the adjustment circular plate 122 still do not contact the scraper gear 127, and the adjustment circular plate 122 continues to rotate. Under the action of the scraper gear 127, the T-shaped rotating plate 111 cannot continue to rotate, and the torsion spring between the T-shaped rotating plate 111 and the adjustment circular plate 122 is compressed, and finally the teeth of the adjustment circular plate 122 contact the scraper gear 127.

Then the separation motor 110 is started to drive the double-headed threaded screw 109 to rotate, so that the upper base plate 103 and the lower base plate 104 move away from each other, that is, the T-shaped slide plate 129 moves downward, and the spring between the T-shaped slide plate 129 and the strip slide plate 130 is compressed.

Under the action of the cleaning push rod 114, the metal residues in the through holes on the upper base plate 103 and the casting holes on the upper mold 106 are pushed downward. When the cleaning push rod 114 completely pushes out the metal residues in the through holes on the upper base plate 103 and the casting holes on the upper mold 106, the torsion spring between the T-shaped rotating plate 111 and the adjusting circular plate 122 is completely recovered, that is, the position of the T-shaped rotating plate 111 does not change at this time.

Under the action of the bevel gear 132 and the bevel gear 2 133, the T-shaped rotating plate 111 contacts the limiting round block 128 and cannot continue to rotate, and the auxiliary rack 131 continues to move upward. The adjustment circular plate 122 rotates so that the teeth on the adjustment circular plate 122 contact the scraping gear 127. The adjustment circular plate 122 continues to rotate, and the scraping gear 127 rotates, so that the scraping shaft 123, the scraping strip 125, and the scraping strip 1256 rotate synchronously, so that the scraping strip 2 126 first rotates to contact the lower surface of the upper mold 106, and the metal residue on the lower surface of the upper mold 106 is scraped off. Then the scraping strip 125 contacts the upper surface of the lower mold 105 and the demoulding slide 107, and the metal residue on the upper surface of the lower mold 105 and the demoulding slide 107 is scraped off.

[0042] Working principle: Start the separation motor 110 to drive the double-headed threaded screw 109 to rotate, so that the lower mold 105 and the upper mold 106 are engaged, and a casting chamber is formed between the lower mold 105, the upper mold 106, and the demoulding slide 107, and then start the auxiliary motor 121 to drive the auxiliary screw 124 to rotate, so that the T-shaped slide 129 and the strip slide 130 move downward synchronously, and under the action of the T-shaped slide 129, the lower surface of the demoulding slide 107 and the upper surface of the lower base plate 104 are on the same plane, and then the molten metal is poured into the chamber formed between the lower mold 105, the upper mold 106, and the demoulding slide 107 through the through hole on the upper mold 106 and the pouring hole on the upper base plate 103.

[0043] After the metal liquid in the chamber formed between the lower mold 105, the upper mold 106, and the demoulding slide 107 is cooled, the separation motor 110 is started to drive the double-headed threaded screw 109 to rotate, so that the upper bottom plate 103 and the lower bottom plate 104 move away from each other, so that the upper bottom plate 103 and the lower bottom plate 104 move to make the lower surface of the upper mold 106 and the upper surface of the scraping strip 126 on the same plane and the lower surface of the scraping strip 125 and the upper surface of the demoulding slide 107 on the same plane, and then the auxiliary motor 121 is started to drive the strip slide 1 30 moves upward, that is, the T-shaped slide plate 129 moves upward, the T-shaped slide plate 129 contacts the lower surface of the demoulding push plate 116, and the demoulding push plate 116 moves upward, the spring between the demoulding push plate 116 and the lower bottom plate 104 is compressed, that is, the demoulding slide plate 107 slides upward in the lower mold 105, under the action of the demoulding slide plate 107, the metal residue on the inner wall of the lower mold 105 is scraped off, and the demoulding slide plate 107 moves the cast metal standard parts to the outside of the lower mold 105, so as to facilitate the removal of the cast metal standard parts.

[0044] After the metal standard parts to be cast are removed, the auxiliary motor 121 is started to continue to drive the strip slide 130 to move upward, the spring between the strip slide 130 and the T-shaped slide 129 is compressed, and under the action of the auxiliary rack 131, the bevel gear 132, the bevel gear 2 133, and the auxiliary gear 134, the adjustment circular plate 122 rotates, and the T-shaped rotating plate 111 rotates synchronously, so that the T-shaped rotating plate 111 rotates to the top of the upper bottom plate 103. At this time, the T-shaped rotating plate 111 contacts 7, and the adjustment circular plate 122 continues to rotate, and the T-shaped rotating plate 111 rotates to the top of the upper bottom plate 103. The torsion spring between the rotating plate 111 and the adjusting circular plate 122 is compressed, and finally the teeth on the adjusting circular plate 122 contact the scraping gear 127. The scraping gear 127 does not rotate at this time, and then the separation motor 110 is started to drive the upper base plate 103 and the lower base plate 104 to move away from each other. The cleaning push rod 114 engages with the through holes on the upper base plate 103 and the casting holes on the upper mold 106. Under the action of the cleaning push rod 114, the metal residues in the through holes on the upper base plate 103 and the casting holes on the upper mold 106 are pushed downward.

[0045] After the metal residues in the through holes on the upper base plate 103 and the pouring holes on the upper mold 106 are cleaned, the upper base plate 103 and the lower base plate 104 are moved to the position after demolding is completed, and then the auxiliary motor 121 is started to drive the strip slide 130 to move upward, so that the teeth on the adjustment circular plate 122 contact the scraping gear 127, and the scraping gear 127 rotates, and the scraping shaft 123, scraping strip 1 125, and scraping strip 2 126 rotate synchronously, and scraping strip 2 126 scrapes and cleans the metal residues on the lower surface of the upper mold 106, and scraping strip 1 125 scrapes and cleans the metal residues on the upper surfaces of the lower mold 105 and the demolding slide 107.

[0046] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
