Description

Technical Field

[0001] The utility model relates to the field of product injection molding, in particular to a mold suitable for a suction nozzle. Background Art

[0002] like Figure 1-2 As shown, Figure 1 , 2 It is a structural diagram of the suction nozzle. As can be seen from the figure, in the structure of the suction nozzle, a circularly distributed buckle position is provided in the cylindrical notch structure, and the buckle position is distributed in a ring with the notch structure as the center.

[0003] It is not difficult to see that the structure of the nozzle is quite complicated. In addition to replacing the mold core, it is necessary to consider how to demold. The conventional demolding action is to separate the upper mold and the lower mold directly. For this nozzle with multiple buckles, this separation cannot successfully demold. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a mold suitable for a suction nozzle, aiming to solve the problem that the traditional mold cannot demould the suction nozzle.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a mold suitable for a suction nozzle, having a mold body including an injection molding space formed by a mold core assembled in a mold cavity, characterized in that a guide member is arranged in the lower mold part, and the mold core is composed of an actuator guided to rotate by the guide member and a supporting member that is static relative to the above-mentioned actuator. The guiding member allows the molding block on the actuator that assists in buckling molding to rotate and stagger its original relative position with the buckle.

[0006] Furthermore, an ejection mechanism for demolding is provided in the mold body, and the guide component includes a fixing part positioned in the mold body, and a guide track extending from the periphery of the actuator, and the two ends of the guide track are in a staggered relationship formed by at least one bend in the middle part of the actuator, and the actuator is pushed by the ejection mechanism and rotates under the guidance of its own guide track.

[0007] Furthermore, a mounting seat connected to the actuator is provided on the output end of the ejection mechanism, and the side surface of the end where the actuator is connected to the mounting seat is a recess structure. A space for the actuator to enter is reserved on the mounting seat, and in the above space, there is a limiting structure located in the recess, and the actuator rotates back and forth under the constraint of the limiting structure.

[0008] Furthermore, there is a lifting plate located in the injection molding space, wherein the lifting plate has a lifting surface extending to the entire edge of the suction nozzle, and the lifting plate is connected to the lifting part of the ejection mechanism.

[0009] Furthermore, a part of the supporting member is a pin that acts on the inside of the suction nozzle.

[0010] Furthermore, the fixing member is composed of a pin inserted into the guide track and a fixing nut, the fixing nut is fixed on the mold body, and the side of the pin is a notch that abuts against the side edge of the fixing nut.

[0011] Beneficial effects of the utility model:

[0012] The molding block in the mold core used to assist in the buckle position molding is guided by the guide component to perform a rotational action during the demolding action, thereby changing the positional relationship between the molding block and the buckle position. In other words, the mold of the utility model has the rotational action required for the above-mentioned suction nozzle, thereby meeting all the prerequisites for preparing this suction nozzle and solving the problem of the current lack of molds for preparing this suction nozzle.

[0031] like Figure 3 As shown, the utility model is a mold suitable for a suction nozzle 3.

[0032] Figure 3 The utility model is shown in a schematic diagram after mold closing.

[0033] from Figure 6 It can be seen that the mold core is divided into two types, one is an executive component that can both rotate and support the injection liquid, and the other is a supporting component 2 that only plays a supporting role. The design of this executive component is to cope with the buckle position 3a in the product suction nozzle 3. During demolding, the molding block 1a on the executive component that supports the buckle position 3a can be staggered and avoided by rotation. In the subsequent demolding action, the suction nozzle 3 can be smoothly pushed out from the lower mold part D2.

[0034] In summary, the mold of the utility model provides the rotational action required for application to this product (suction nozzle 3), so as to change the positional relationship between the molding block 1a and the buckle position 3a. In other words, the mold of the utility model has the rotational action required for the above-mentioned suction nozzle 3, thereby meeting all the prerequisites for preparing this suction nozzle 3 and solving the current problem of lack of molds for preparing this suction nozzle 3.

[0035] like Figure 1-14 As shown, in the present invention, the existing ejection mechanism 4 and the upper mold part D1 are adopted (the ejection mechanism 4 and the upper mold part D1 mentioned above belong to the prior art, so the specific structure is not repeated), and the ejection mechanism 4 is the source power for the suction nozzle 3 to separate from the lower mold part D2.

[0036] In this embodiment, the execution component includes a cylindrical first insert 1, and the first insert 1 is kept in a vertical posture to rotate. This rotation is realized in a purely physical structure and is specifically embodied by the guide component.

[0037] The guide member is located in the lower mold part D2, and the guide member is divided into two parts. One part is the guide track 5a formed on the outer periphery of the first insert 1, and the other part is located in the guide track 5a and is a fixed part that is static relative to the first insert 1. The two ends of the guide track 5a are based on the area between each other because at least one of them is tortuous, forming a staggered position (the two ends are staggered up and down). The first insert 1 is connected to the output end of the ejection mechanism 4. When the position of the fixed part remains unchanged, the first insert 1 during the demolding process climbs and rotates upward along its own guide track 5a, so that the molding block 1a and the buckle position 3a are staggered.

[0038] It should be noted that the climbing and rotation of the first insert 1 are synchronized, and when the first insert 1 climbs upward, the suction nozzle 3 will also be lifted up by the lifting plate 6 synchronously to prevent the first insert 1 from piercing through the suction nozzle 3.

[0039] In short, during the demoulding operation, the lifting plate 6 and the first insert 1 move synchronously.

[0040] The lifting plate 6 is a part of the injection molding space (the injection molding space is formed by assembling the mold core in the mold cavity). The lifting plate 6 is installed on the output end of the ejection mechanism 4 through a connector. Under the action of the support member 2, the injection solution forms the edge of the bottom of the suction nozzle 3 on the lifting plate 6. In the embodiment, this edge is annular (the lifting plate 6 has a lifting surface extending to the entire edge of the bottom of the suction nozzle 3).

[0041] There is also a mounting seat 7 that penetrates into the first upper top plate 41 of the ejection mechanism 4. The mounting seat 7 is a structure that is adapted to the end of the first insert 1 and can take into account the climbing and rotation of the first insert 1 at the same time.

[0042] An opening space is reserved on the mounting seat 7 for the first insert 1 to enter, and a cutout structure 1b is provided on the local side surface at the end of the first insert 1. The inner side surface of the opening space extends to a limiting structure 7a in the cutout structure 1b. The upper and lower edges of the limiting structure 7a are in the cutout structure 1b to prevent the first insert 1 from detaching from the mounting seat 7. In the embodiment, the surfaces opposite to the cutout structure 1b and the limiting structure 7a are parallel to each other. This is a special choice made in combination with the tortuosity of the guide track 5a. This is to control the rotation amplitude of the first insert 1 to avoid excessive rotation amplitude that may cause damage to the suction nozzle 3 when removing the material.

[0043] The above-mentioned material removal method provides a thrust to the bottom edge of the suction nozzle 3, so that the suction nozzle 3 is subjected to a more uniform force as a whole and is not easily damaged.

[0044] Specifically, there is also an internal lifting and stripping method that cooperates with the above-mentioned edge stripping method; specifically, a part of the supporting member 2 is a pin 2a, and the end of the pin 2a extends to the second upper top plate 42, and is pushed by the second upper top plate 42 to push the suction nozzle 3 out of the supporting member 2. This method of lifting and stripping from the inside of the suction nozzle 3 can evenly distribute the force of ejecting the suction nozzle 3 on the whole, which can improve the efficiency of stripping and can also avoid the situation where the suction nozzle 3 is unevenly subjected to force during stripping, resulting in a burst of friction.

[0045] The static state of the fixing member relative to the first insert 1 should be understood as the first insert 1 rotating relative to the fixing member.

[0046] In practice, the first insert 1 and the fixing member both move up and down synchronously.

[0047] The bottom of the support member 2 extends through the jacking plate 6, and the fixing member is connected to the bottom of the support member 2.

[0048] The fixing part includes a pin 5b and a nut 5c. The pin 5b is inserted into the guide track 5a from the mold core. A notch is set at the outer end of the pin 5b. The nut 5c is fixed on the mold core and offset with the notch formed by the pin 5b. This structure is mainly reflected in a simple assembly method.

[0049] Other slides, mechanisms, and devices not mentioned in this technical solution all belong to the prior art and all adopt the structure of conventional molds. Therefore, they will not be elaborated in detail in this solution.

[0050] The demoulding process of the utility model is:

[0051] Fig.15 Schematic diagram after mold closing. When demolding, the lifting plate 6 and the ejector pin 2a first push the suction nozzle 3 upward for a certain distance, such as Fig.16 As shown in the figure, the first insert 1, the ejector pin 2a and the suction nozzle 3 all have an upward movement, so that the molding block 1a on the first insert 1 is separated from the supporting members except the lifting plate 6. Fig.17 As shown, the first insert 1 can avoid interference with the above-mentioned supporting member when rotating; after the buckle position 3a and the forming block 1a are completely offset, the suction nozzle 3 is completely ejected from the lower mold part D2 by the lifting plate 6 for a second time (as shown in FIG. Fig.18 shown).

[0052] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention.
