Description

Technical Field

[0001] The present application relates to the technical field of injection molding machines, and in particular to a separate shooting platform device and an injection molding machine. Background Art

[0002] Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. The main structure of the injection molding machine includes the injection part and the molding part. The material is melted in the injection part and pushed to the molding part, and finally the corresponding injection molded parts are produced in the molding part.

[0003] The existing injection part generally integrates melting and injection into one device part, which is suitable for continuous injection molding of general size. When it comes to injection molding of precision micro plastic products, the manufacturing cost of conventional integrated injection devices and the difficulty of injection molding process will increase. In order to solve the above problems, a shooting platform structure with separated melting and injection has appeared on the market. For example, the Chinese utility model patent with announcement number CN219236051U discloses "a mixed color injection molding machine", which separates melting and injection independently, so that the melting advancement amount and injection advancement amount of the material can be controlled independently, which is suitable for injection molding of tiny plastic products. However, at the same time, since the melting component is above the injection component and the two have a certain angle, in order to ensure that the material can be smoothly transported from the melting material tube to the injection material tube, the installation accuracy between the melting component and the injection component is required. In the prior art, the melting component and the injection component are only connected by a fixed plate at the tail of the two, and the adjustment of the two during the installation process cannot be achieved. Utility Model Content

[0004] In order to facilitate the adjustment of the relative position between the melt-melting component and the injection component during the installation process, the first purpose of the present application is to provide a separate injection platform device.

[0005] The present application provides a separate shooting platform device adopting the following technical solution:

[0006] A separate shooting platform device includes a guide frame and further includes:

[0007] The injection assembly is arranged on the guide frame;

[0008] A melt-melting component connected to the injection component and located above the injection component; and

[0009] An adjusting assembly, used to connect the melt adhesive assembly and the guide frame, the adjusting assembly comprising an adjusting seat and an adjusting pin connected to the adjusting seat;

[0010] The adjusting seat is arranged on the guide frame, the adjusting pin is rotatably connected to the melt adhesive assembly, and the adjusting seat is also provided with a first adjusting groove for the adjusting pin to slide.

[0011] By adopting the above technical solution, the melt glue and the injection glue assembly are separated and independently arranged so that the two operations of melt glue and injection glue are performed separately, which can be applied to the molding process of small injection molding products. Secondly, the melt glue assembly is placed above the injection glue assembly and the relative rotation of the two is achieved through the adjustment assembly. In the process of adjusting the melt glue assembly and the injection glue assembly, the angle between the two can be easily adjusted. At the same time, the opening of the first adjustment groove allows the melt glue assembly to slide relative to the injection glue assembly, which further facilitates the relative position of the two, making installation and debugging more convenient.

[0012] Preferably, the adjusting pin comprises a main body section and connecting sections connected to both sides, the main body section is rotatably connected to the melt-adhesive component, and the connecting section is extended outward from the inside of the melt-adhesive component; wherein, the main body section and the connecting section are stepped, the adjusting seat has a limiting opening for partially accommodating the melt-adhesive component, the first adjusting groove is connected to the limiting opening, the main body section is placed in the limiting opening and the two end faces are in contact with the two end faces of the opening of the first adjusting groove, and the connecting section extends to the first adjusting groove and can slide relative to each other.

[0013] By adopting the above technical scheme, the main body of the adjusting pin is rotatably connected to the melt-glue assembly, and the connection between the adjusting pin and the adjusting seat realizes the relative rotation between the melt-glue assembly and the injection assembly. A stepped arrangement is adopted between the main body section and the connecting sections at both ends, so that when the adjusting pin is connected to the adjusting seat, the end face of the main body section can contact the limiting opening of the adjusting seat to realize preliminary positioning, and the connecting section extends into the first adjusting groove to further limit the melt-glue assembly and the injection assembly in one direction in advance. At the same time, the sliding of the connecting section in the first adjusting groove also facilitates the quick adjustment of the relative position between the melt-glue assembly and the injection assembly.

[0014] Preferably, the connecting section has at least one positioning surface that conflicts with the first adjustment groove.

[0015] By adopting the above technical solution, the setting of the positioning surface can firstly make it faster to adjust the relative position between the melt-adhesive component and the injection-adhesive component, and at the same time, the contact area is increased by the interference between the positioning surface and the first adjustment groove, thereby improving the support stability of the melt-adhesive component.

[0016] Preferably, the adjustment assembly further comprises a first locking member, one end of which can extend into the first adjustment slot and be connected to the adjustment pin.

[0017] By adopting the above technical solution, the first locking member can fix the relative position between the adjusting pin and the adjusting seat after the relative position adjustment is completed, thereby realizing the relative position limitation between the melt-melting component and the injection component.

[0018] Preferably, the adjustment assembly further comprises a second locking member for connecting the adjustment seat and the injection assembly, and the adjustment seat is further provided with a second adjustment groove at the end surface, and the second locking member can extend into the second adjustment groove for relative sliding.

[0019] By adopting the above technical solution, the relative position adjustment between the melt-glue component and the injection component can also be achieved by changing the position between the adjustment seat and the injection component. The second locking member is used to fix the adjustment seat and the injection component after the relative position adjustment is completed, further increasing the stroke range of the position adjustment between the melt-glue component and the injection component.

[0020] Preferably, the adjustment assembly further comprises a fixing seat, which is arranged at the end of the melt-melting assembly and is simultaneously connected to the injection assembly.

[0021] By adopting the above technical solution, after the relative positions of the melt-melting component and the injection-molding component are adjusted, the fixing seat completely limits the relative positions of the two.

[0022] Preferably, the injection assembly comprises:

[0023] Injection machine barrel,

[0024] Drive motor;

[0025] A transmission screw rod, the transmission screw rod is connected to the drive motor;

[0026] A screw nut, threadedly connected to the transmission screw;

[0027] An injection push rod, one end of which extends into the injection machine barrel; and

[0028] The injection molding limit seat connects the lead screw nut and the injection molding push rod.

[0029] By adopting the above technical solution, the screw nut pair is used to realize the axial reciprocating movement of the injection push rod in the injection machine barrel, thereby realizing the ejection of the molten material. The transmission form of the screw nut pair has higher precision and is more conducive to the ejection control of the molten material of small injection molding products.

[0030] Preferably, it also includes a whole-shift assembly, and the whole-shift assembly includes:

[0031] a cylinder body, wherein the cylinder body is arranged on the guide frame; and

[0032] A piston rod, wherein the piston rod can slide axially relative to the cylinder body, and one end of the piston rod extends out of the cylinder body;

[0033] Wherein, the injection limiting seat is slidably connected to the cylinder body.

[0034] By adopting the above technical solution, the whole moving assembly is used to drive the entire shooting platform device away from or close to the clamping module to achieve the connection between the nozzle and the mold. In addition to strengthening the strength of the guide frame, the cylinder body in the whole moving assembly can also play the role of guiding the guide rod. The sliding of the injection limit seat on the cylinder body can achieve the guided sliding of the injection assembly, which optimizes the structure and reduces the manufacturing cost.

[0035] Preferably, the whole-movement components are symmetrically distributed on both sides of the injection component.

[0036] By adopting the above technical solution, the injection molding assembly and the entire injection molding device slide more smoothly during movement and are subjected to more uniform load force.

[0037] In order to facilitate the adjustment of the relative position between the melt-melting component and the injection component during the installation process, the second purpose of the present application is to provide an injection molding machine.

[0038] The present application provides an injection molding machine that adopts the following technical solution:

[0039] An injection molding machine, comprising the separate shooting platform device

[0040] By adopting the above technical solution, the melt-glue component and the injection-glue component can conveniently adjust the connection angle and relative position by using the setting of the adjustment component.

[0041] In summary, the present application includes at least one of the following beneficial technical effects:

[0042] 1. Through the rotational connection between the adjusting pin in the adjusting assembly and the melt assembly, and the adjusting pin can slide in the first adjusting groove of the adjusting seat, the melt assembly can be rotated and translated relative to the injection assembly, which is convenient for rapid adjustment of installation and debugging;

[0043] 2. Through the structural setting of the adjustment pin stage, the melt-adhesive component can be limited in a certain direction when the position is adjusted relative to the injection component. At the same time, the interference between the positioning surface and the first adjustment groove further increases the contact area between the adjustment pin and the adjustment seat to further achieve the positioning effect, thereby improving the support stability of the melt-adhesive component;

[0044] 3. The cylinder in the whole moving assembly has the functions of guide rod and connecting rod at the same time, which simplifies the structure of the whole shooting platform and reduces the manufacturing design cost. BRIEF DESCRIPTION OF THE DRAWINGS

The term "and / or" used herein includes any and all combinations of one or more related listed items. Embodiment 1

[0057] Figure 1 The structure of a separate shooting platform device is shown, including a guide frame 1 and a melt assembly 3 and an injection assembly 2 arranged on the guide frame 1. The melt assembly 3 is mainly used to melt the material and push it to the end, and the injection assembly 2 is used to push the molten material into the mold gate. In this embodiment, the injection assembly 2 is installed on the guide frame 1, and the melt assembly 3 is connected to the injection assembly 2 at a certain angle and is above the melt assembly 3. The two are separated and independently arranged.

[0058] Combination Figure 2 The injection assembly 2 includes an injection barrel 21, a driving motor 22, a transmission screw 23, a screw nut 24, an injection limit seat 26 and an injection push rod 25. The driving motor 22 is mounted on the guide frame 1 and connected to the transmission screw 23 through a synchronous belt transmission mode, and is used to drive the transmission screw 23 to rotate. The screw nut 24 is mounted around the outside of the transmission screw 23 and is threadedly connected to the transmission screw 23. One end of the injection limit seat 26 is connected to the screw nut, and the other end is connected to the injection push rod 25. When the driving motor 22 is working, the rotation of the transmission screw 23 is converted into linear propulsion by the screw nut 24, and the injection limit seat 26 is driven to perform linear reciprocating motion with the injection push rod 25. The injection push rod 25 extends into the injection barrel 21. When the molten material in the melt assembly 3 enters the material channel in the injection barrel 21, it can be pushed to the nozzle of the injection assembly 2 for feeding through the injection push rod 25.

[0059] The glue melting assembly 3 includes a glue melting barrel 31, a screw 32 and a hydraulic motor 34. The hydraulic motor 34 is connected to the screw 32 through a coupling 33. The screw 32 is placed in the glue melting barrel 31. The glue melting barrel 31 is also provided with a feed channel 35. The material enters through the feed channel 35 and is heated and melted. The rotation of the hydraulic motor 34 drives the screw 32 to rotate. The rotation of the screw 32 drives the molten material to be transported to the discharge channel of the glue melting barrel 31 and finally enters the glue injection assembly 2.

[0060] The guide frame 1 is also provided with an adjustment component 4 and a fixing seat 6. The adjustment component 4 is used to connect the melt assembly 3 and the injection assembly 2, and also plays a role in adjusting the angle and relative position of the melt assembly 3 relative to the injection assembly 2. The adjustment component 4 is located at a relatively middle position between the injection assembly 2 and the melt assembly 3. The fixing seat 6 is connected to the end of the melt barrel 31 and is also connected to the injection barrel 21. After the melt assembly 3 is installed and adjusted in position, the melt assembly 3 and the injection assembly 2 are completely limited by the setting of the fixing seat 6.

[0061] Shared Reference Figure 3 and Figure 4 The adjusting assembly 4 includes an adjusting seat 41 and an adjusting pin 42. The adjusting seat 41 is mounted on the guide frame 1. A connecting seat 36 is provided on the outer wall of the melt machine barrel 31. The connecting seat 36 extends outward from the outer circumference of the melt machine barrel 31. The connecting seat 36 has a pin hole 361. The adjusting pin 42 is arranged in the pin hole 361. The entire melt machine assembly 3 can rotate relative to the adjusting pin 42.

[0062] The adjustment seat 41 is provided with a limiting opening 411, and the connection seat 36 can extend into the limiting opening 411. The length of the adjustment pin 42 is greater than the depth of the pin hole 361 so that both ends extend out of the pin hole 361. The adjustment seat 41 is also provided with a first adjustment groove 412, which is a through groove and is horizontally provided. Both ends of the adjustment pin 42 can extend into the first adjustment groove 412 and can slide in the first adjustment groove 412, thereby realizing the position adjustment of the melt assembly 3 relative to the injection assembly 2.

[0063] The adjustment assembly 4 further includes a first locking member 43 and a second locking member 44. One end of the first locking member 43 can extend into the first adjustment groove 412 and be connected to the adjustment pin 42, thereby limiting the sliding of the melt assembly 3 in the first adjustment groove 412. The adjustment seat 41 is also provided with a second adjustment groove 413. The second adjustment groove 413 has a certain length. The second locking member 44 can slide in the second adjustment groove 413 to achieve a position change of the adjustment seat 41 relative to the guide frame 1 to adjust the position between the melt assembly 3 and the injection assembly 2. At the same time, the second locking member 44 can pass through the second adjustment groove 413 to connect with the guide frame 1 to lock the position of the adjustment seat 41 relative to the guide frame 1.

[0064] See also Figure 5In another embodiment, the adjusting pin 42 is in a staged shape as a whole and includes a main section 421 and connecting sections 422 located on both sides of the main section 421. The connecting section 422 has at least one positioning surface. In this embodiment, the positioning surfaces are respectively arranged on both sides of the connecting section 422. When the connecting seat 36 is in the limiting opening 411, the two ends of the main section 421 abut against the first adjusting groove 412, thereby limiting the movement of the melt adhesive assembly 3 in one direction on the horizontal plane. At the same time, the connecting section 422 extends into the first adjusting groove 412 and the positioning surface abuts against the groove surface of the first adjusting groove 412, thereby improving the guidance during sliding.

[0065] See also Figure 6 The fixing seat 6 is roughly L-shaped, and its two ends are respectively connected to the melt-melting machine barrel 31 and the injection-molding machine barrel 21. When the fixing seat 6 is connected, the relative positions of the melt-melting component 3 and the injection-molding component 2 are fixed.

[0066] Shared Reference Figure 7 and Figure 8 The present shooting platform device also includes a whole moving assembly 5, which includes a cylinder body 51 and a piston rod 52 disposed in the cylinder body 51. One end of the piston rod 52 is connected to a connecting rod 53, and the connecting rod 53 is connected to an external clamping assembly. The guide frame 1 is a split type including a head plate 11 and a tail plate 12. The cylinder body 51 connects the head plate 11 and the tail plate 12. A slider 13 is also provided at the bottom of the guide frame 1. A guide rail 14 cooperating with the slider 13 is provided on the entire external frame. When the whole moving assembly 5 is working, it can drive the entire shooting platform device to slide along the guide rail 14. In addition, the injection limit seat 26 in the injection assembly 2 is slidably connected to the cylinder body 51 to guide the sliding of the injection limit seat 26.

[0067] During the installation and debugging of the separate shooting platform device, the position of the adjustment seat 41 relative to the guide frame 1 is pre-installed, and then the melt-glue component 3 is assembled with the adjustment seat 41. After the two ends of the adjustment pin 42 enter from one end of the first adjustment groove 412 and slide to the designed position, the first locking member 43 is installed and connected to the adjustment pin 42, and the horizontal sliding of the melt-glue component 3 is limited. Finally, the angle between the melt-glue component 3 and the injection component 2 is adjusted and the fixing seat 6 is installed for complete adjustment. Embodiment 2
