[0022] Move the two clamping strips upward to compress the compression spring, place the screw rod through the upper side of the inner wall of the two placement slots, loosen the two clamping strips, and move the two clamping strips downward through the compression spring. At the same time, the clamping strips drive the clamping plate downward. When the clamping plate contacts the side of the screw rod, the resistance force generated by the contact between the screw rod and the clamping plate causes the T-shaped rod to move upward and stretch the tension spring, so that the tension spring is in a taut state, and the thinner screw rod can be clamped through the clamping plate and the lower side of the inner wall of the placement slot.

[0023] The reciprocating screw is driven by the motor to rotate, and the internal threaded sleeve is limited by the through slot, so that the internal threaded sleeve drives the T-shaped block and the cleaning brush to move back and forth. At this time, the screw is rotated, and the cleaning brush can quickly remove impurities such as iron filings on the upper side of the screw. At the same time, the T-shaped block drives the scraper to move back and forth, scraping the impurities on the top of the support seat to the left and right sides of the support seat, so that the impurities on the top of the screw and the support seat can be quickly collected and cleaned.

[0029] The following is combined with Figure 1-4 The utility model is described in further detail.

[0030] Please refer to the attached figure in the instruction manual Figure 1 、 Figure 2 and Figure 3 The utility model provides an embodiment: a fixed frame for producing screw rods of an injection molding machine, comprising a support base 1, a C-shaped support plate 2 is fixedly provided on the top of the support base 1, a placement groove 3 is opened in the middle of the top surface of the two vertical plates of the C-shaped support plate 2, a movable groove 4 is opened on the front and rear sides of the placement groove 3, and a clamp 5 is slidably provided inside each of the four movable grooves 4 in a group of two, and a motor 6 is fixedly provided on the left side of the horizontal plate on the left side of the C-shaped support plate 2;

[0031] A through groove 7 is provided in the middle of the side surface of the horizontal plate of the C-shaped support plate 2. A reciprocating screw rod 8 is rotatably connected to the side surface of the inner wall of the through groove 7. The right end of the reciprocating screw rod 8 is fixedly connected to the output end of the motor 6. An internal threaded sleeve 10 is movably sleeved on the side surface of the reciprocating screw rod 8. The side surface of the internal threaded sleeve 10 is slidably connected to the inside of the through groove 7. A cleaning piece 9 is fixedly provided on the front side of the internal threaded sleeve 10.

[0032] Working principle: When using the fixed frame for screw production of the injection molding machine, first move the two clamping strips 501 upward to compress the compression spring 502 and increase the spacing at the bottom of the inner wall of the placement slot 3. Then place the screw to be placed through the upper side of the inner wall of the two placement slots. Then relax the two clamping strips 501 so that the two clamping strips 501 move downward by the rebound force of the compression spring 502. At the same time, the clamping strip 501 drives the clamping plate 504 to move downward. When the clamping plate 504 contacts the side of the screw, the resistance force generated by the contact between the screw and the clamping plate 504 causes the T-shaped rod 503 to move upward and stretch the tension spring 505, so that the tension spring 505 is in a taut state, and the thinner screw can be clamped by the clamping plate 504 and the lower side of the inner wall of the placement slot 3.

[0033] The reciprocating screw 8 is driven to rotate by the rotating shaft of the motor 6, and the internal threaded sleeve 10 is limited by the through groove 7, so that the internal threaded sleeve 10 slides back and forth left and right, and the T-shaped block 901 and the cleaning brush 902 are driven to move back and forth by the internal threaded sleeve 10. At this time, the screw is rotated to enable the cleaning brush 902 in a moving state to quickly remove impurities such as iron filings on the upper side of the screw. At the same time, the T-shaped block 901 drives the scraper 903 to move back and forth, and then scrapes the impurities on the top of the support seat 1 to the left and right sides of the support seat 1, so that the impurities on the top of the screw and the support seat 1 can be quickly collected and cleaned.

[0034] It should be noted that the card member 5 includes two card strips 501, which are slidably connected to the inside of the movable grooves 4 in a group of two. The top of the card strips 501 is fixedly connected to two compression springs 502, and the top of the compression springs 502 is fixedly connected to the upper side of the inner wall of the movable groove 4. The top of the card strips 501 is movably inserted into the limiting block 506.

[0035] By adopting the above technical solution, a thinner screw can be stably clamped by the limit block 506 .

[0036] It should be noted that the limit block 506 includes a T-shaped rod 503, which is movably inserted into the upper side of the card strip 501. The bottom end of the vertical rod of the T-shaped rod 503 passes through the lower side of the card strip 501 and is fixed with a card plate 504. The card plate 504 and the middle part of the card strip 501 are both arc-shaped. The side fixed sleeve of the vertical rod of the T-shaped rod 503 is provided with a tension spring 505. The top of the tension spring 505 is fixedly connected to the bottom of the horizontal rod of the T-shaped rod 503, and the bottom end of the tension spring 505 is fixedly connected to the upper side of the card strip 501.

[0037] By adopting the above technical solution, the releasing area between the middle part of the arc-shaped clamping plate 504 and the clamping strip 501 and the side surface of the screw is larger.

[0038] It should be noted that the cleaning piece 9 includes a T-shaped block 901, the rear side of the T-shaped block 901 is fixedly connected to the front side of the internal threaded sleeve 10, the front side of the T-shaped block 901 is fixedly connected to a cleaning brush 902, and the lower side of the vertical block of the T-shaped block 901 is fixedly connected to a scraper 903.

[0039] By adopting the above technical solution, the burrs and other impurities on the upper side of the screw can be easily cleaned by the cleaning brush 902.

[0040] It should be additionally explained that the lower side of the scraper strip 903 contacts the top of the support base 1 , and the cross-section of the scraper strip 903 is in the shape of an isosceles triangle.

[0041] By adopting the above technical solution, the bottom of the scraper strip 903 having an isosceles triangle cross section is sharper, thereby achieving a better cleaning effect on the upper side of the support seat 1 .

[0042] It should be supplemented that a long block 904 is fixedly provided on the lower side of the scraper strip 903 , and a long slot 905 that matches the long block 904 is opened on the top of the support base 1 .

[0043] By adopting the above technical solution, the cooperation between the long block 904 and the long slot 905 facilitates the vertical and stable sliding of the scraping bar 903, thereby conveniently scraping off the burrs such as iron filings on the upper side of the screw to both sides for easy cleaning.

[0044] It should be noted that the front side of the top of the support base 1 has an inclination angle of 45°.

[0045] By adopting the above technical solution, the burrs and other iron filings on the upper side of the screw can be easily cleaned off from the upper side of the support base 1 through the support base 1 that is tilted at the front side.

[0046] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
