Other desirable properties include biocompatibility, biodegradability, and the ability to induce regeneration.

[0003] In conventional cases, the downward pushing method is generally used to reflect the mechanical situation when the sample is pushed out, but it cannot reflect the actual situation when clinicians push the product upward, such as in maxillary sinus lift. Therefore, a push-in force test mold for push-in products is designed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a mold for testing the injection force of injection products.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold for testing the injection force of injection-type products, comprising an inverted concave frame, a lower pressure tool, a hydraulic rod, and an upper pressure tool. The lower pressure tool is fixedly installed on the bottom inner side of the inverted concave frame, and the hydraulic rod is fixedly installed on the center of the upper surface of the inverted concave frame. The upper pressure tool is fixedly installed at the output end of the hydraulic rod. An injection device is placed on the lower pressure tool, and a sleeve is sleeved above the injection device. The outer surface of the sleeve is engraved with millimeter scales.

[0010] Preferably, the diameter of the rolled edge of the outer sleeve is smaller than the inner diameter of the sleeve, and a rolled edge plate is provided through the outer sleeve of the injector, with a through hole provided on the rolled edge plate.

[0011] Preferably, the diameter of the through hole is not less than the diameter of the injector sleeve, and the diameter of the through hole is less than the diameter of the sleeve's rolled edge.

[0012] Preferably, the diameter of the through hole is larger than the diameter of the outer rolled edge, and the inner left and right sides of the rolled edge sleeve are provided with mounting grooves, in which an insert strip is fixedly installed by a spring.

When the ejector sleeve passes through the through hole on the rolled edge sleeve plate, the embedded strip is pushed into the mounting groove. The spring is compressed, and the spring force ensures that the embedded strip is tightly against the side of the ejector sleeve. When the diameter of the rolled edge of the ejector sleeve is smaller than the diameter of the through hole, the embedded strip adheres to the outer surface of the ejector sleeve until the rolled edge of the ejector sleeve contacts the embedded strip, thus achieving the effect of supporting the sleeve. This design is suitable for testing ejectors of different sizes, increasing its practicality. Attached Figure Description

The lower pressure tool 2 is fixedly installed on the bottom inner side of the inverted concave frame 1. The hydraulic rod 3 is fixedly installed in the center of the upper surface of the inverted concave frame 1. The upper pressure tool 4 is fixedly installed at the output end of the hydraulic rod 3. A pusher is placed on the lower pressure tool 2. A sleeve 6 is sleeved above the pusher. The outer surface of the sleeve 6 is engraved with millimeter scale 601.

[0033] The injector includes an injector sleeve 5, a push handle 501, a piston 502, and an outer sleeve rolled edge 503. The piston 502 is embedded inside the injector sleeve 5, the push handle 501 is fixedly installed at the bottom of the piston 502, and the outer sleeve rolled edge 503 is fixedly installed at the bottom of the outer surface of the injector sleeve 5.

[0034] In this embodiment, the hydraulic rod 3 is electrically connected to the electronic universal testing machine, and a pressure sensor is installed on the bottom surface of the upper pressure fixture 4, and the pressure sensor is electrically connected to the electronic universal testing machine.

[0035] In this embodiment, the diameter of the outer sleeve 503 is larger than the diameter of the sleeve 6, so that when the sleeve 6 is fitted onto the outer sleeve 5 of the injector, the outer sleeve 503 limits the position of the sleeve 6.

[0036] When using the machine, set the parameters of the testing machine, such as the pressing speed and displacement. Place the pusher handle 501 on the lower pressure plate 2, and sleeve 6 on the outer sleeve 5 of the pusher. The bottom of sleeve 6 contacts the outer sleeve rolled edge on the outer sleeve 5 of the pusher. Start the instrument, and the hydraulic cylinder drives the upper pressure plate 4 to move downward. The upper pressure plate will press down to the specified displacement according to the parameters set by the testing machine. The parameters such as the pushing force are displayed by the degree of the testing machine, and the displacement is calculated according to the millimeter scale 601 on sleeve 6 to achieve the effect of upward push assistance test.

[0037] In this embodiment, the diameter of the outer sleeve 503 is smaller than the inner diameter of the sleeve 6, and the outer sleeve 5 of the injector is provided with a rolled edge plate 7 through it, and the rolled edge plate 7 is provided with a through hole 701.

[0038] First embodiment of the rolled edge sleeve 7:

[0039] In this embodiment, the diameter of the through hole 701 is not less than the diameter of the injector sleeve 5, and the diameter of the through hole 701 is less than the diameter of the sleeve rolled edge 503.

[0040] When the diameter of the outer sleeve 503 is smaller than the inner diameter of the sleeve 6, the outer sleeve 5 of the injector can pass through the through hole 701 on the crease plate 7. The bottom of the crease plate 7 contacts the outer sleeve 503. When the sleeve 6 is fitted onto the outer sleeve 5 of the injector, the sleeve 6 will contact the upper surface of the crease plate 7, thereby achieving the effect of positioning the crease plate 7.

[0041] Second embodiment of the rolled edge sleeve 7:

[0042] In this embodiment, the diameter of the through hole 701 is larger than the diameter of the outer sleeve rolled edge 503, and the inner left and right sides of the rolled edge sleeve plate 7 are provided with mounting grooves 703, and the embedded strip 702 is fixedly installed in the mounting groove 703 by spring 704.

[0043] In this embodiment, the mounting groove 703 passes through the through hole 701, and when the spring 704 is in a naturally extended state, the insert strip 702 extends into the through hole 701.

[0044] In this embodiment, the embedded strip 702 is trapezoidal in shape, and the thickness of the part of the embedded strip 702 extending into the through hole 701 is reduced.

[0045] By providing an insert strip 702 that passes through the through hole 701, when the ejector sleeve 5 passes through the through hole 701 on the rolled edge sleeve 7, the insert strip 702 is pushed into the mounting groove 703. The spring 704 is in a compressed state, and the elastic force of the spring 704 can make the insert strip 702 fit tightly against the side of the ejector sleeve 5. When the diameter of the rolled edge 503 on the ejector sleeve 5 is smaller than the diameter of the through hole 701, the insert strip 702 is attached to the outer surface of the ejector sleeve 5 until the rolled edge 503 on the ejector contacts the insert strip 702, which can achieve the effect of supporting the sleeve 6. This is suitable for testing ejectors of different sizes and increases practicality.

[0046] In this embodiment, a rubber suction cup 201 is fixedly installed in the center of the upper surface of the lower pressure fixture 2, and a push plate is fixedly installed at the bottom of the push handle 501. The diameter of the rubber suction cup 201 is smaller than the side length of the push plate. The rubber suction cup 201 can adsorb the push plate onto the lower pressure fixture 2. With the setting of the rubber suction cup 201, the push plate at the bottom of the push handle 501 on the injector is attached to the rubber suction cup 201 on the lower pressure fixture 2, thereby achieving the effect of fixing the push handle 501 and the injector on the lower pressure fixture 2, ensuring the stability and vertical state of the injector during testing.

[0047] In this embodiment, a connecting plate 401 is fixedly installed on the inner surface of the upper presser 4, and a guide sleeve 402 is fixedly provided at the inner end of the connecting plate 401. The guide sleeve 402 is sleeved on the inverted concave frame 1.
