Description

Technical Field

[0001] The present invention relates to the technical field of dental medical device manufacturing, and particularly to an integrated forming device for synchronous bending during injection molding of a metal probe. Background Art

[0002] Dental metal probes are indispensable and commonly used instruments in oral diagnosis and treatment, mainly undertaking two core functions: First, mechanical cleaning of hard deposits, that is, using its metal tip to directly and effectively remove hard attachments such as dental calculus and plaque deposited on the tooth surface through physical friction; Second, palpation examination, which is used to gently contact and explore the gums, periodontal pockets and other oral soft tissues to evaluate their health status, texture, bleeding points and sensitivity, and is an important auxiliary means for diagnosing periodontal diseases and oral mucosal lesions. Therefore, the precise forming of the probe (especially the bending design at a specific angle) and the stable and hygienic plastic handle encapsulation are crucial for its function realization, operation feel and service life.

[0003] Currently, in the industry, the manufacturing of such dental instruments with bent metal probes generally adopts the following step-by-step and labor-dependent process route:

[0004] Step 1: Pre-bending and shaping of the metal probe: First, a straight metal wire (usually stainless steel) is pre-processed into a specific bending angle and shape that meets clinical requirements through a dedicated bending device or mold.

[0005] Step 2: Manual placement and injection molding: Subsequently, the operator needs to manually pick up and precisely place the pre-bent and shaped metal probe into the predetermined cavity of the injection mold. Finally, after the metal probe is positioned, the mold is closed for injection molding of the middle area of the metal probe.

[0006] However, this processing method significantly increases the production cycle and labor costs due to the step-by-step operations (bending, transferring, placing, injection molding); the manual placement link is prone to introducing operation errors, resulting in position and angle deviations of the probe in the mold, directly affecting the dimensional accuracy, symmetry and feel balance of the final product. The product quality stability highly depends on the proficiency and concentration of the operator; it is difficult to achieve a continuous and efficient fully automated production line, restricting the improvement of production capacity and economies of scale.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] As Figure 1 、 Figure 2 shown, for the purpose of eliminating the manual operation of pre-bending and realizing the automation of synchronous bending and injection molding, the present invention provides an integrated molding device for synchronous bending and injection molding of metal probes. This device mainly includes two major parts: the front mold 1 and the rear mold 2:

[0060] Front mold 1: It includes the A plate 10, and the injection molding part 11, the fixed part 12 of the front mold core insert, and the movable part 13 of the front mold core insert installed in the A plate 10.

[0061] Rear mold 2: It includes the B plate 20, and the fixed part 21 of the rear mold core insert and the movable part 22 of the rear mold insert installed in the B plate 20.

[0062] The A plate 10 and the B plate 20 are precisely closed through guide pillars and guide sleeves. Before mold closing, the straight metal probe 3 (see Figure 3 ) that has not been pre-bent is placed in place, and its two ends are respectively embedded in the specially designed card slots 220 on the fixed part 12 of the front mold core insert and the fixed part 21 of the rear mold core insert to achieve precise positioning. The middle region of the metal probe 3 that needs to be injection-molded and coated is located in the molding groove 221 jointly formed by the front and rear mold core fixing parts.

[0063] During mold closing or injection molding, the movable part 13 of the front mold core insert and the movable part 22 of the rear mold insert cooperate to directly apply the required bending force to the positioned straight metal probe 3, and complete the multi-stage bending molding of the first bending section, the second bending section, and the third bending section in one time in the mold (see Figure 4 ).

[0064] In addition, the co-injection part is started, and the molten material is injected into the molding groove 221 to perform precise overmolding on the middle area (i.e., the overmolding section) of the metal probe 3. After the injection molding, pressure holding, and cooling are completed, the mold is opened, and the movable insert is reset, and then multiple finished metal probe 3 products that have completed all the bending (the first, second, and third sections) and have a complete overmolding in the middle area can be taken out at one time.

[0065] In short, by using the movable insert parts (the movable part 13 of the front mold core insert and the movable part 22 of the rear mold insert) in the front and rear molds, within the same cycle of mold closing and injection molding, the pre-positioned straight metal probe 3 is directly bent in multiple stages (forming the first, second, and third bending sections) inside the mold, and the middle area after its bending and shaping is overmolded synchronously or immediately afterwards (forming the overmolding section), so as to output the final product in one automated cycle, completely eliminating the links of manual pre-bending and placing the bent parts.

[0066] As Figure 5 and Figure 6 shown, the card slot 220 is a V-shaped guiding groove, and its cross-section has a symmetrical V-shaped geometric structure, with the included angle between the two inclined planes being 15° - 85°, and the bottom of the groove is a rounded bottom or a flat bottom transition.

[0067] As Figures 9 - 11 shown, the movable part 13 of the front mold core insert includes a first bending unit 130 and its front mold first driving unit. The first bending unit 130 is designed as a T-shaped structure and is composed of a base part 1301 and a first bending head 1302. Correspondingly, a first bending groove 2100 (see Figure 6 ) that precisely matches the first bending head 1302 is provided on the fixed part 21 of the rear mold core insert.

[0068] Guide rods 1303 are installed on both sides of the base part 1301, and first springs 1304 are sleeved on the guide rods 1303. On the one hand, it buffers the rigid impact generated when the first bending unit 130 descends to protect the metal probe 3 from damage; on the other hand, when the mold is opened or the first driving unit retracts, it provides an auxiliary reset force to help the first bending unit 130 quickly return to the initial position.

[0069] The working surface of the first bending head 1302 is provided with an arc-shaped groove 1305. During the bending process, the arc-shaped groove 1305 directly contacts the metal probe 3 and serves as a force application point to guide and perform the precise bending and forming action of the metal probe 3. The base part 1301 of the first bending unit 130 is driven by a first front mold driving unit (such as an oil cylinder, a cylinder, or a lifter mechanism) so that it can stably descend in the vertical direction. When descending, the first bending head 1302 moves downward accordingly, gradually pressing the metal probe 3 embedded in the slot 220 of the fixing part of the rear mold insert 21 into the lower first bending groove 2100, thereby realizing the progressive bending and forming of the first bending section of the metal probe 3.

[0070] As Figure 12 shown, the movable part 13 of the front mold insert further includes a second bending unit 131 and its independent second front mold driving unit. The second bending unit 131 also adopts a T-shaped structure, but a through hole 1310 penetrating the entire unit is designed on its side surface, and a mounting groove is machined on one of its side surfaces. The elastic spring pin assembly 132 is installed in the mounting groove and mainly consists of the following components:

[0071] Mounting block 1320: Fixed to the side end of the second bending unit 131 and serving as the base of the assembly.

[0072] Spring pin 1321: Its rod part is restricted in the mounting groove by the mounting block and is precisely aligned with the through hole 1310 on the side surface. The spring pin 1321 can slide horizontally in the through hole 1310, and its extended end is used to directly contact and push the metal probe 3 during bending.

[0073] Second spring 1322: Sleeved outside the spring pin 1321 and pre-compressed between the spring pin 1321 and the inner wall of the mounting groove. The second spring 1322 provides the elastic force required for the horizontal movement of the spring pin 1321 and is responsible for resetting the spring pin 1321 after the action is completed.

[0074] At the position corresponding to the second bending unit 131 on the fixing part 21 of the rear mold insert, an inclined guiding slope 2101 is designed (see Figure 13) When the second bending unit 131 vertically descends driven by the second driving unit of the front mold, the end (non-working end) of the spring pin 1321 mounted on it will contact the inclined guiding slope 2101 of the fixed part 21 of the insert of the rear mold core. As the second bending unit 131 continues to descend, the squeezing effect of the guiding slope 2101 on the end of the spring pin 1321 continues to increase. This vertically downward movement is converted into a lateral thrust through the inclined plane, driving the spring pin 1321 to move laterally inward (towards the metal probe 3) along the through hole 1310 against the resistance of the second spring 1322; the protruding end (working end) of the laterally moving spring pin 1321 then strongly abuts against the pre-positioned metal probe 3, applying a precisely controlled lateral bending force, thereby realizing the forming of the second bending section of the metal probe 3. When the second bending unit 131 rises and returns to its original position driven by the driving unit, the end of the spring pin 1321 disengages from the squeezing of the guiding slope 2101. At this time, the compressed second spring 1322 releases energy, pushing the spring pin 1321 to move laterally outward and completely retracting into the through hole 1310, restoring to its initial state to prepare for the next working cycle.

[0075] As Figure 7 shown, the movable part 22 of the rear mold insert includes a third bending unit 222 and its rear mold driving unit. After the mold is closed and locked, the rear mold driving unit (such as an oil cylinder, ejector rod mechanism) is activated, driving the third bending unit 222 to steadily rise in the vertical direction; when the third bending unit 222 rises, the working surface at its top will precisely contact and upwardly push a predetermined specified part of the metal probe 3, applying the bending force required to complete the third bending section.

[0076] As Figure 10 , at the same time, the fitting groove 1200 located on the fixed part 12 of the front mold core insert completely matches the final target shape of the metal probe 3 after the third bending. Specifically, the cavity profile of the fitting groove 1200 matches the target shape of the metal probe 3 after bending, and is used to limit the displacement path of the metal probe 3 when the third bending unit 222 rises. When the third bending unit 222 upwardly pushes the metal probe 3, the corresponding part of the metal probe 3 is forced to enter and fit into the cavity of the preset fitting groove 1200; the rigid inner wall of the fitting groove 1200 strictly limits the displacement path and deformation trajectory of the metal probe 3 at this part, ensuring that it can only be bent according to the preset and correct shape; during the entire upward bending process, the top profile of the third bending unit 222 maintains a precise dynamic cooperation relationship with the inner wall of the fitting groove 1200, enabling the fitting groove 1200 to provide passive shape constraint and guidance, precisely guiding the deformation direction and shaping the final profile.

[0077] As Figure 8As shown in the figure, to ensure the precise fixation of the metal probe 3 before bending and injection molding and prevent displacement from affecting the quality, a set of positioning and clamping fixtures, namely the front mold fixture 14 and the rear mold fixture 23, are equipped on both the front mold 1 and the rear mold 2. Each set of fixtures includes the following components:

[0078] A cylinder 240, fixedly installed on the corresponding base of the front mold 1 or the rear mold 2, provides power;

[0079] A push plate 241, one end of which is directly connected to the output end of the cylinder 240. When the cylinder 240 operates, it drives the push plate 241 to perform a reciprocating linear motion in the horizontal direction;

[0080] A long strip-shaped push piece 242, rigidly fixed at the end of the push plate 241. Along its length direction, a plurality of convex 2420 structures are equidistantly arranged on the long strip-shaped push piece 242;

[0081] On the end face of each convex 2420 facing the moving direction of the metal probe 3, a V-shaped groove 2421 is machined.

[0082] After the A plate 10 and the B plate 20 are closed, before the bending action starts and before the injection molding begins, the placed metal probe 3 is still in a relatively loose state and needs to be precisely fixed; at this time, the cylinder 240 is activated to push the connected push plate 241 to move horizontally; the movement of the push plate 241 drives the long strip-shaped push piece 242 at its front end to move horizontally synchronously, and the convex 2420 and its V-shaped groove 2421 on the long strip-shaped push piece 242 move accordingly; the moving long strip-shaped push piece 242 makes the V-shaped groove 2421 of each convex 2420 contact the corresponding metal probe 3. The included angle of the two inclined surfaces of the V-shaped groove 2421 can automatically guide and accommodate the rod part of the metal probe 3; as the long strip-shaped push piece 242 continues to move horizontally, the contact force between the inclined surface of the V-shaped groove 2421 and the metal probe 3 stably pulls the metal probe 3 towards and tightly fits it on the preset positioning surfaces on the front mold insert fixing part 12 and the rear mold insert fixing part 21; after moving in place, the metal probe 3 is firmly clamped between the V-shaped groove 2421 and the positioning surfaces of the front and rear mold fixing parts, eliminating all loose degrees of freedom. During the entire bending and injection molding process, the cylinder 240 maintains pressure to ensure that the metal probe 3 remains stationary at all times. After the process is completed, the cylinder 240 acts in the reverse direction, driving the long strip-shaped push piece 242 to retract and releasing the clamping force for mold opening to take out the finished product.

[0083] To precisely control the mold temperature during the injection molding process, ensure uniform filling of the plastic melt, rapid cooling and shaping, and reduce product deformation, both the front mold 1 and the rear mold 2 are integrated with water channels; the water channels include the front mold water channel and the rear mold water channel. The front mold water channel is arranged in the A plate 10, and the rear mold water channel is arranged in the B plate 20. Among them, the front mold water channel and the rear mold water channel are arranged opposite to each other.

[0084] Considering the maintainability, lifespan of the mold and the replaceability of the inserts, the fixing part 12 of the front mold core insert and the fixing part 21 of the rear mold core insert are detachably connected to the A plate 10 and the B plate 20 respectively.

[0085] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
