Description

Technical Field

[0001] This utility model relates to the field of mold core pulling technology, specifically a simplified inclined angle internal tooth core pulling mechanism. Background Technology

[0002] Core pulling is used to handle areas on the parting surface of a product that cannot be demolded. It belongs to the "undercut processing system" and is a structure of the mold. The definition of core pulling is: a mechanism that ensures the smooth demolding of the product, also called a slider.

[0003] Traditional mold core pulling requires the use of multiple sliders, which is quite complex. It can only pull cores from a single mold, making the actual demolding process slow and complicated, thus affecting its ease of use.

[0004] Therefore, a simplified inclined angle internal tooth core-pulling mechanism is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a simplified inclined angle internal tooth core-pulling mechanism, which can solve the problem of the complex and slow demolding core-pulling process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a drive shaft and a drive bevel gear fixedly sleeved on the outer side of one end of the drive shaft. The drive bevel gear is meshed with at least two driven bevel gears. An auxiliary gear is provided behind the driven bevel gear. The auxiliary gear and the driven bevel gear are fixedly sleeved on the same support shaft. The auxiliary gear is meshed with a connecting gear. A transmission cylinder is provided through the middle of the connecting gear. A molded body is inserted into one end of the transmission cylinder.

[0007] Preferably, the two driven bevel gears are symmetrically distributed on opposite sides of the driving bevel gear, and limit blocks are provided on both sides of the driven bevel gear and the driving bevel gear.

[0008] Preferably, the connecting gear is fixedly sleeved on the outside of the transmission cylinder, and the middle part of the transmission cylinder is a through-type cylindrical structure.

[0009] Preferably, a pull rod extends through the middle of the transmission cylinder, and the pull rod is inserted into the interior of the molded body.

[0010] Preferably, the pull rod and the transmission cylinder are arranged at the same angle, and the included angle between the transmission cylinder and the molded body is greater than 90°.

[0011] Preferably, the two molded bodies are arranged in parallel and symmetrical distribution, and a spring is provided at the end of the pull rod away from the molded body.

[0012] Preferably, the transmission cylinder and the pull rod are connected to a support block, the support block has a rotating groove inside, the connecting gear is rotatably disposed inside the rotating groove, and the connecting gear extends out of the outside of the rotating groove.

[0013] Compared with the prior art, this utility model provides a simplified inclined angle internal tooth core-pulling mechanism, which has the following beneficial effects:

[0014] 1. Through the meshing transmission of the driving bevel gear and the driven bevel gear, and the meshing transmission of the driven bevel gear and the connecting gear, the transmission cylinder can rotate at a different height from the driving shaft. The simultaneous rotation of the two transmission cylinders forces the connection part with the molded body to be disengaged, thus creating the effect of demolding and core pulling inside the molded body.

[0015] 2. By setting a certain angle between the transmission cylinder and the molding body, the effect of internal tooth core pulling at an angle is formed, which ensures the safety of the relative position of the two molding bodies when they are demolded at the same time, and ensures the stability and accuracy of the demolding action of the device.

[0016] 3. By setting the two molded bodies in parallel, the positions of the two molded bodies will not affect each other when the rotating demolding parts on both sides are running, thus improving the stability and safety of demolding. Attached Figure Description

[0022] 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. Example

[0023] Please see Figure 1 - Figure 4 A simplified inclined internal tooth core-pulling mechanism in this embodiment includes a drive shaft 1 and a drive bevel gear 2 fixedly sleeved on the outer side of one end of the drive shaft 1. The drive bevel gear 2 is meshed with at least two driven bevel gears 3. An auxiliary gear 4 is provided behind the driven bevel gears 3. The auxiliary gear 4 and the driven bevel gears 3 are fixedly sleeved on the same support shaft. The auxiliary gear 4 is meshed with a connecting gear 5. A transmission cylinder 6 is provided through the middle of the connecting gear 5. A molded body 8 is inserted into one end of the transmission cylinder 6.

[0024] First, by connecting and installing the drive shaft 1 to the external drive source, and providing corresponding support components for the rotation of the drive shaft 1, drive bevel gear 2, driven bevel gear 3, auxiliary gear 4, and connecting gear 5, since the support components are conventional technical means in this field, they are not described in detail in this embodiment.

[0025] Through the meshing transmission of the driving bevel gear 2 and the driven bevel gear 3, and the meshing transmission of the driven bevel gear 3 and the connecting gear 5, the transmission cylinder 6 can rotate at different heights from the driving shaft 1. By rotating the two transmission cylinders 6 simultaneously, the connection part between them and the molded body 8 is forcibly disengaged, forming a demolding and core-pulling effect inside the molded body 8. Thus, under the control of a single drive source, two molded bodies 8 can be demolded and core-pulled simultaneously, improving demolding efficiency.

[0026] Two driven bevel gears 3 are symmetrically distributed on the corresponding sides of the driving bevel gear 2, and limit blocks are provided on both sides of the driven bevel gears 3 and the driving bevel gear 2;

[0027] By symmetrically arranging the two driven bevel gears 3, the two driven bevel gears 3 can drive in the same direction, ensuring the stability and reliability of the connection between the two traditional parts.

[0028] The connecting gear 5 is fixedly sleeved on the outside of the transmission cylinder 6, and the middle part of the transmission cylinder 6 is a through-type cylindrical structure;

[0029] A pull rod 7 passes through the middle of the transmission cylinder 6 and is inserted into the interior of the molded body 8;

[0030] The pull rod 7 and the transmission cylinder 6 are set at the same angle, and the included angle between the transmission cylinder 6 and the molding body 8 is greater than 90°.

[0031] Based on the connection and fixation between the pull rod 7 and the molding body 8, the molding body 8 is provided with a fixed position support effect, so that when the transmission cylinder 6 rotates with the connecting gear 5, the contact part between the transmission cylinder 6 and the molding body 8 rotates, forming a rotation demolding effect.

[0032] Furthermore, by setting a certain angle between the transmission cylinder 6 and the molding body 8, the effect of internal tooth core pulling at an angle is formed, ensuring the safety of the relative position of the two molding bodies 8 when they are demolded at the same time, and ensuring the stability and accuracy of the demolding action of the device.

[0033] The two molded bodies 8 are arranged in parallel and symmetrically, and a spring 11 is provided at the end of the pull rod 7 away from the molded body 8;

[0034] A support block 9 is inserted into the transmission cylinder 6 and the pull rod 7. A rotating groove 10 is opened inside the support block 9. The connecting gear 5 is rotatably disposed inside the rotating groove 10 and extends out of the outside of the rotating groove 10.

[0035] By setting the two molding bodies 8 in parallel, the positions of the two molding bodies 8 will not affect each other when the rotating demolding parts on both sides are running, thus improving the stability and safety of demolding. After the transmission cylinder 6 rotates, the pull rod 7 is pulled backward by the buffer of the spring 11, so that the pull rod 7 is disengaged from the contact part with the molding body 8, and finally the effect of positioning the internal tooth core is achieved.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
