Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical technology, and in particular to an auxiliary device for repairing syringe molds. Background Technology

[0002] The production process of pre-filled syringes requires injection molding using a mold. The mold has multiple arrayed die holes, into which a syringe core is inserted. The core is inserted into the die hole from the front. The core has a threaded blind hole at its bottom, and the die hole has a threaded through hole at its bottom. A screw is inserted through the threaded blind hole and screwed into the threaded through hole to secure the core in the die hole. After a period of use, the mold needs to be inspected, and cores that no longer meet requirements are replaced. During inspection and replacement, the core is inspected from the front. If a problem is found, the corresponding core is removed and ejected from the back. Then, the new core is placed into the die hole from the front, and a screw is inserted from the bottom of the die hole from the back to secure the new core. Because there are multiple cores, the process involves repeated inspection and manipulation from both the front and back, making it tedious and time-consuming.

[0003] In existing technologies, lifting molds using forklifts requires at least two people working on the front and back of the mold respectively. This not only demands excellent teamwork and a high level of skill from the operators, but also exposes them to the risk of slippage and detachment due to the wire rope lifting operation, thus increasing safety hazards for the workers. Furthermore, the forklift requires protective timber underneath to prevent scratching the mold, but the timber is prone to slippage and detachment, further increasing the safety risk. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model proposes a pre-filled syringe mold repair platform to solve the safety hazards existing in the repair of syringe molds in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A pre-filled syringe mold repair platform includes a bracket and a support platform rotatably connected to the bracket for supporting and fixing the mold. The support platform has a hollow center to expose the back of the mold. A wheel is provided on one side of the support platform for rotating it. A fixing element is inserted between the wheel and the bracket to secure the rotated support platform. This invention makes the mold more stable by fixing it to the support platform, avoiding the safety hazard of slipping. The rotation of the support platform allows the mold to be flipped vertically, facilitating collaborative work by two people on both sides, or allowing a single operator to flip the mold for separate work on both sides. The wheel facilitates the rotation of the support platform, and the fixing element allows for easy insertion into the wheel and bracket to secure the rotated support platform.

[0007] Furthermore, in order to ensure that the fastener is stably inserted into the bracket, the front end of the fastener is provided with an external thread, and the bracket is provided with an internal thread hole that matches the external thread.

[0008] Furthermore, to facilitate the insertion of the fastener, the wheel is symmetrically distributed with multiple through holes for the fastener to be inserted, and the through holes can be aligned with the internal threaded holes respectively.

[0009] Furthermore, to facilitate the screwing of the fastener onto the bracket, the fastener includes a threaded pin and a screwing handle located at the rear end of the threaded pin.

[0010] Furthermore, in order to form a stable support, the support includes two inverted T-shaped supports arranged in parallel and spaced apart, with the lower parts of the two inverted T-shaped supports connected by a connecting beam; the support platform is rotatably connected between the upper ends of the two inverted T-shaped supports.

[0011] Furthermore, the support platform is provided with rotating shafts at both ends, and the rotating shafts are respectively rotatably mounted on the upper ends of two inverted T-shaped brackets; and the wheel is connected to one of the rotating shafts.

[0012] Furthermore, to facilitate the overall movement of the maintenance platform, the lower ends of the two inverted T-shaped brackets are equipped with rollers.

[0013] Furthermore, to facilitate easy installation and removal of the mold, the mold is detachably connected to the support platform by bolts.

[0014] Furthermore, to facilitate the quick removal of bolts and unloading of the mold after loosening the bolts and nuts, the mold is provided with a first U-shaped slot that runs through both sides of the mold, and the opening of the first U-shaped slot extends out of the side of the mold; the support platform is provided with a side opening facing the side, and a second U-shaped slot for the bolt to pass through is provided on the side of the side opening near the mold, and the opening of the second U-shaped slot extends out of the side of the support platform, and the opening of the second U-shaped slot is aligned with the opening direction of the first U-shaped slot so that the bolt and the nut connected to the bolt can be removed from the openings of the first U-shaped slot and the second U-shaped slot.

[0015] Furthermore, in order to ensure that the back of all the mold holes on the entire mold can be exposed, the support platform is a rectangular frame structure made of four square tubes or square steel connected together.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model makes the mold more stable by connecting it to a support platform, thus avoiding the safety hazard of slipping.

[0018] 2. This utility model uses a support platform that is rotatably connected to a bracket, allowing the mold to be flipped as needed. The mold can be flipped to a vertical position, which is convenient for two people to work together on both sides, or for a single operator to flip the mold to work on both sides separately.

[0019] 3. This utility model provides a convenient rotating support platform by setting a wheel, and a pin that can be inserted into the hole of the wheel and then into the hole of the bracket to fix the rotating support platform. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 As shown in Embodiment 1 of this utility model, a mold repair platform for a pre-filled syringe includes a bracket 1 and a support platform 3 rotatably connected to the bracket 1. The mold 4 is connected to the support platform 3 so that the support platform 3 supports and fixes the mold 4. The middle of the support platform 3 is hollowed out to expose the back of the mold hole 41 on the mold 4, facilitating the removal of the screws at the bottom of the mold hole 41 to remove the mold core to be replaced or to insert screws to fix the new mold core after replacement. The rotatable connection of the support platform 3 to the bracket 1 facilitates front inspection, back removal of the mold core, front insertion of the mold core, and back fixation of the mold core by the operator. A wheel 2 for rotating the support platform 3 is provided on one side, facilitating manual rotation of the mold.Figure 2 As shown, a fixing piece 6 is inserted between the wheel 2 and the bracket 1 to fix the support platform 3 after rotation.

[0026] In a preferred embodiment, such as Figure 1 As shown, the support platform 3 is a rectangular frame structure formed by connecting four square tubes or square steel.

[0027] In another preferred embodiment, the front end of the fixing member 6 is provided with an external thread, and the bracket 1 is provided with an internal thread hole that matches the external thread, so that the fixing member 6, which passes through the wheel 2 and is inserted into the bracket 1, is threadedly connected to the bracket, thereby providing a more stable fixation of the wheel 2 and preventing the support platform 3 from rotating.

[0028] Furthermore, the wheel 2 has multiple through holes for inserting the fixing member 6 arranged symmetrically around the rotation axis of the support platform 3, and each through hole can be aligned with an internal threaded hole. In this embodiment, the support platform 3 is rotatably connected to the bracket 1 via a rotating shaft, and the wheel 2 is connected to one end of the rotating shaft. The wheel 2 and the rotating shaft are coaxially arranged, meaning that the rotation axis of the support platform 3 passes through the axis of the wheel 2. Therefore, multiple through holes are symmetrically distributed on the wheel 2 around the axis of the wheel 2. Each through hole can be aligned with an internal threaded hole after the support platform 3 rotates a certain angle, so that the fixing member can be screwed into the internal threaded hole after passing through the through hole.

[0029] Specifically, the fixing member 6 includes a threaded pin and a screw handle located at the rear end of the threaded pin. The screw handle facilitates the rotation of the fixing member 6.

[0030] Example 2 differs from Example 1 in that, as Figure 1 As shown, the support 1 includes two inverted T-shaped supports arranged in parallel and at intervals. The support platform 3 is rotatably connected between the upper ends of the two inverted T-shaped supports, that is, rotatably connected to the upper ends of the vertical parts of the two inverted T-shaped supports. The lower parts of the two inverted T-shaped supports are connected by a connecting beam; and the two ends of the connecting beam are connected to the middle position of the lower part of the inverted T-shaped supports to avoid hindering the workers from working between the two inverted T-shaped supports at the positions corresponding to the front and back of the mold.

[0031] Example 3 differs from Example 2 in that, as Figure 1 and Figure 2 As shown, the support platform 3 has a rotating shaft at both ends, and the two rotating shafts are respectively inserted through the upper ends of the vertical parts of the two inverted T-shaped brackets. The outer end of one of the rotating shafts is connected to the wheel 2.

[0032] Example 4 differs from Example 2 in that, as Figure 1As shown, the lower ends of the two inverted T-shaped brackets are equipped with rollers. In this embodiment, the lower ends of the inverted T-shaped brackets, that is, the lower sides of both ends of the horizontal portion of the inverted T-shaped brackets, are rotatably connected to rollers, which facilitates the overall movement of the maintenance platform.

[0033] Example 5 differs from Example 1 in that, as Figure 1 and Figure 2 As shown, the mold 4 is detachably connected to the support platform 3 by bolts 5.

[0034] Furthermore, each side of the mold 4 is provided with two first U-shaped slots penetrating both the front and back surfaces of the mold 4. The openings of the first U-shaped slots protrude from the side of the mold 4, that is, the openings of the first U-shaped slots penetrate the side of the mold 4 closest to the first U-shaped slot, and simultaneously penetrate both the front and back surfaces at that location. This facilitates the bolt 5 to pass through from the front and then into the support platform 3, and also facilitates the removal of the bolt 5 with the nut 7 attached from the side. The support platform 3 is provided with a side opening 31 facing the side of the support platform 3, and the opening direction of the side opening 31 is consistent with the opening direction of the first U-shaped slots. On the side of the side opening 31 near the mold 4, there is a second U-shaped slot for the bolt 5 to pass through, so that the bolt 5 passes through the second U-shaped slot and enters the side opening 31, and the nut 7 is located in the side opening 31. Moreover, the opening of the second U-shaped slot protrudes from the side of the support platform 3, which is the side where the opening of the side opening 31 is located. The second U-shaped slot opening faces the same direction as the first U-shaped slot opening, allowing the bolt 5 and the nut 7 connected to the bolt 5 to be removed from the openings of the first and second U-shaped slots. The nut 7 is a T-shaped nut, which facilitates tightening against the top of the side opening 31, i.e., the bottom of the second U-shaped slot, thereby making the bolt-nut connection more secure.

[0035] Furthermore, the first U-shaped slot has a step, meaning it is divided into an upper U-shaped slot near the front of the mold 4 and a lower U-shaped slot near the back of the mold 4. The width of the upper U-shaped slot is greater than the width of the lower U-shaped slot. The width of the upper U-shaped slot is also greater than the width of the nut end of the bolt 5, while the width of the lower U-shaped slot is less than the width of the nut end of the bolt 5. This ensures that after the bolt 5 passes through the first U-shaped slot and connects to the nut 7, the nut end of the bolt 5 is located within the upper U-shaped slot and does not protrude from the front of the mold 4.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some or all of the technical features thereof, within the spirit and principles of the present invention, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
