Description

Technical Field

[0001] This utility model relates to a molding protection device for pre-filled syringes, belonging to the field of molding protection devices. Background Technology

[0002] In the daily production of pharmaceutical glass, pre-filled products require clamping equipment during molding. However, the clamping equipment currently used for pre-filled products lacks protective devices during the molding process, resulting in direct metal contact with the high-temperature product. This causes a sharp drop in product temperature, leading to breakage, reducing the yield and quality of the product. Furthermore, the equipment cannot quickly replace damaged products after use, significantly reducing production efficiency. Summary of the Invention

[0003] Based on the problems described in the background, the problem to be solved by this utility model is to provide a pre-filled syringe molding protective device, which solves the problem of cracking caused by rapid cooling of products in contact with high temperatures through a specially designed protective plate and clamp, and also solves the problem of not being able to quickly replace the product during replacement.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pre-filled syringe molding protective device is provided, including a processing base, clamping arms, clamps and protective plates. Three sets of clamping arms are installed above the processing base, clamps are installed at the front end of the clamping arms, and protective plates are installed on the clamps.

[0005] The processing base includes a processing base and rotating connecting columns. The processing base is cylindrical, and three sets of rotating connecting columns are vertically installed on the edge of the upper surface of the processing base.

[0006] The clamping arm includes an arm body, a connecting hole, a clamping head guard plate, bolt holes, and snap-fit ​​holes. The arm body is in the shape of a "6" boss. A step is provided in the middle part of the arm body. The connecting hole is opened at the bottom of the clamping arm. The clamping head guard plate is installed on both sides of the top of the arm body. The bolt hole is opened in the middle of the top of the arm body. A snap-fit ​​hole is provided at the junction of the end of the clamping head guard plate and the arm body.

[0007] The chuck includes a head body, a second chuck guard plate, a snap-fit ​​post, a protective plate groove, a bolt countersunk hole, and a positioning ball. The head body is square in shape. The second chuck guard plate is installed at the bottom of the head body and is vertical. The snap-fit ​​post is installed on the second chuck guard plate and at the junction of the second chuck guard plate and the head body. The protective plate groove is installed on the upper surface of the head body and its upper end is flush with the upper end face of the head body. The bolt countersunk hole is opened in the middle part of the head body. The positioning ball is installed at the upper end of the protective plate groove.

[0008] The protective plate includes a plate body and positioning holes. The plate body is square in shape, and positioning holes are provided at the upper ends of both sides of the plate body.

[0009] Preferably, the processing base is installed by using a rotating connecting post to engage with the connecting hole of the clamping arm. The diameter of the rotating connecting post is the same as the diameter of the connecting hole, which facilitates installation and engagement, as well as disassembly.

[0010] Preferably, the clamping arm is installed by using the snap-fit ​​hole and the snap-fit ​​post of the clamp head. The bolt hole of the clamping arm matches the bolt countersunk hole of the clamp head. In this way, the clamp head can be fixed to the clamping arm by installing a countersunk bolt at one end of the clamp head. There is no bolt protrusion, which can also ensure the installation of the protective plate.

[0011] Preferably, the clamp is connected to the positioning hole of the protective plate through a positioning ball. The internal width of the protective plate groove is the same as the thickness of the plate body, which can ensure that the protective plate is stuck in it without falling off, and is also easy to disassemble.

[0012] Preferably, the protective plate is made of carbon fiber, and the material can be replaced to better prevent the cooling rate from being too fast.

[0013] Working principle: The clamping arm is installed on the rotary connecting column of the machining base, and the chuck is installed on the front end of the clamping arm. First, it is positioned and fixed through the snap-fit ​​holes and snap-fit ​​columns. Then, the chuck is fixed to the clamping arm with countersunk bolts, ensuring that the bolts do not affect the installation and use of the protective plate. Finally, the protective plate is inserted into the protective plate groove of the chuck, and the protective plate is stably fixed inside the chuck by the positioning ball and positioning hole. At the same time, during operation, the three sets of clamping arms clamp the pre-filled syringe in the middle. Through force analysis, it can be seen that in addition to the force perpendicular to the working surface, the protective plate and the chuck are also subjected to a force towards the center. This results in the chuck being installed more tightly under the action of the first and second chuck guard plates and the protective plate being installed in the protective plate groove, preventing it from falling off.

[0014] The beneficial effects of this utility model are:

[0015] 1. The uniquely designed protective plate and clamps solve the problem of cracking caused by rapid cooling of products in contact with high temperatures, greatly improving the product yield and quality.

[0016] 2. The replaceable design of the protective plate and clamps allows for quick replacement in case of damage after use, improving production efficiency.

[0017] 3. The unique countersunk bolt design prevents the protective plate from incurring additional wear and tear during installation and use, and also prevents the bolts from coming into contact with high-temperature products, further improving the product yield and quality.

The arm body 21 is in the shape of a boss in the shape of the number "6". A step is provided in the middle part of the arm body 21. The connecting hole 22 is opened at the bottom of the clamping arm 2. The clamping head guard plate 23 is installed on both sides of the top of the arm body 21. The bolt hole 24 is opened in the middle of the top of the arm body 21. A snap-fit ​​hole 25 is provided at the junction of the end of the clamping head guard plate 23 and the arm body 21.

[0029] like Figure 5As shown, the chuck 3 includes a head body 31, a second chuck guard plate 32, a snap-fit ​​post 33, a protective plate groove 34, a bolt countersunk hole 35, and a positioning ball 36. The head body 31 is square plate shaped. The second chuck guard plate 32 is installed at the bottom of the head body 31 and is vertical. The snap-fit ​​post 33 is installed on the second chuck guard plate 32 and is located at the junction of the second chuck guard plate 32 and the head body 31. The protective plate groove 34 is installed on the upper surface of the head body 31 and its upper end is flush with the upper end face of the head body 31. The bolt countersunk hole 35 is opened in the middle part of the head body 31. The positioning ball 36 is installed at the upper end inside the protective plate groove 34.

[0030] like Figure 6 As shown, the protective plate 4 includes a plate body 41 and positioning holes 42. The plate body 41 is square, and positioning holes 42 are provided at the upper ends of both sides of the plate body 41.

[0031] The processing base 1 is installed by using the rotating connecting post 12 in conjunction with the connecting hole 22 of the clamping arm 2. The diameter of the rotating connecting post 12 and the diameter of the connecting hole 22 are the same, which facilitates installation and mating, and also facilitates disassembly.

[0032] The clamping arm 2 is installed by using the buckle hole 25 and the buckle post 33 of the clamp 3. The bolt hole 24 of the clamping arm 2 matches the bolt countersunk hole 35 of the clamp 3. In this way, the clamp 3 can be fixed to the clamping arm by installing a countersunk bolt at one end of the clamp 3. There is no bolt protrusion, which can also ensure the installation of the protective plate 4.

[0033] The clamp 3 is connected to the positioning hole 42 of the protective plate 4 through the positioning ball 36.

[0034] The protective plate 4 is made of carbon fiber, and the material can be replaced to better prevent the cooling rate from being too fast.

[0035] The clamping arm 2 is installed on the rotating connecting column 12 of the processing base 1, and the chuck 3 is installed on the front end of the clamping arm 2. First, it is positioned and fixed through the snap-fit ​​hole 25 and snap-fit ​​column 33. Then, the chuck 3 is fixed on the clamping arm 2 through the countersunk bolt, while ensuring that the bolt does not affect the installation and use of the protective plate 4. Finally, the protective plate 4 is inserted into the protective plate groove 34 of the chuck 3. The protective plate 4 is stably fixed inside the chuck 3 through the positioning ball 36 and positioning hole 42. At the same time, during working clamping, the three sets of clamping arms 2 clamp the pre-filled syringe in the middle. Through force analysis, it can be seen that in addition to the force perpendicular to the working surface, the protective plate 4 and the chuck 3 are also subjected to a force towards the center. This results in the chuck 3 being installed more tightly under the action of the first chuck guard plate 23 and the second chuck guard plate 32, and the protective plate 4 being installed in the protective plate groove 34, so that it will not fall off.
