Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, and more specifically, to a positioning tooling fixture for processing plastic molds. Background Technology

[0002] A plastic mold is a tool used to mold plastic products. Through molding methods such as injection molding, blow molding, and extrusion, plastic raw materials can be transformed into plastic products with specific shapes and sizes, and they are widely used in many industries such as packaging, automotive, and electronics. Positioning fixtures for plastic mold processing are indispensable auxiliary devices in the process. By precisely positioning and firmly clamping the mold, they ensure that the mold is in the correct position during processing, reducing displacement and vibration, improving the processing accuracy of the plastic mold, and ensuring that the produced mold meets design requirements. At the same time, they can effectively improve processing efficiency and reduce the scrap rate.

[0003] In the field of plastic mold processing, positioning fixtures are key equipment to ensure processing accuracy and efficiency. However, current positioning fixtures for plastic mold processing have revealed two major problems in practical applications.

[0004] On the one hand, the flexibility of the fixtures is seriously insufficient. The functions and structures of plastic molding machines vary, and the plastic products produced vary in complexity. This results in a wide variety of types and structures of plastic molds. However, the existing positioning tooling fixtures lack universality. When clamping molds of different sizes and shapes, it is usually necessary to select fixtures that are specifically adapted to them. This not only increases the procurement cost and management difficulty of the fixtures, but also greatly reduces the processing efficiency due to frequent fixture changes, causing great trouble to actual production.

[0005] On the other hand, the mold replacement process is cumbersome and laborious. When it is necessary to replace the mold, the existing tooling fixtures cannot provide convenient assistance. The staff can only move the mold from the workbench to the external transfer vehicle by manual handling. However, some molds are large and heavy. Manual handling not only consumes a lot of physical strength, but also poses safety risks and is prone to accidents. This greatly affects the convenience and smoothness of the work, reduces production efficiency, and brings many troubles to actual use.

[0006] In view of this, we propose a positioning fixture for plastic mold processing. Utility Model Content

[0007] 1. Technical problems to be solved

[0008] The purpose of this utility model is to provide a positioning fixture for plastic mold processing to solve the problems mentioned in the background art.

[0009] 2. Technical Solution

[0010] A positioning fixture for plastic mold processing includes a fixed platform. A control switch is provided on the side wall of the fixed platform. An electric push rod is provided at the bottom of the inner cavity of the fixed platform. A pressure plate is connected to the output end of the electric push rod. A connecting rod is movably sleeved on the top of the fixed platform. A universal ball assembly is connected to the top of a plurality of connecting rods. A plurality of positioning clamping assemblies are also fixedly connected to the top of the fixed platform. Each of the plurality of positioning clamping assemblies includes a fixed circular plate. The plurality of fixed circular plates are fixedly welded to the top of the fixed platform. A limit groove is formed on the top of the plurality of fixed circular plates. A rotating column is rotatably connected to the top of the plurality of fixed circular plates. A connecting plate and a mounting sleeve are fixedly connected to the outer circumference of the rotating column.

[0011] Preferably, the bottom of the plurality of sleeve rods extends into the interior of the fixed platform and is connected to a connecting circular plate, the top of the connecting circular plate being welded with a spring, the end of the spring being connected to the top of the inner cavity of the fixed platform.

[0012] Preferably, a limiting bolt is threaded inside the connecting plate, and the limiting bolt matches the limiting groove.

[0013] Preferably, the top of the mounting sleeve is threaded with a second limiting bolt, and an adjusting rod is slidably connected inside the mounting sleeve. The top of the adjusting rod is provided with a second limiting groove that matches the second limiting bolt.

[0014] Preferably, a threaded rod is threaded onto the outer wall of the end of the adjusting rod, and a mounting bracket is rotatably connected to the end of the threaded rod. A fixing column is fixedly connected to the inner wall of the mounting bracket, and a rubber sleeve is fitted onto the outer circumference of the fixing column.

[0015] Preferably, a guide rod is also fixedly connected to the outer wall of the mounting bracket, and the guide rod is slidably connected to the top of the adjusting rod.

[0016] 3. Beneficial effects

[0017] Compared to existing technologies, the advantages of this invention are as follows: In actual use, the bottom of multiple connecting circular plates can be raised and pressed using an electric push rod, and then the mold can be placed on top of multiple universal ball components. Positioning can then be adjusted on a fixed platform, making the entire adjustment process more labor-saving. Once adjusted to the appropriate position, the electric push rod can drive the pressing plate to descend, allowing multiple sleeve rods to adapt to the shape of the mold bottom through spring compression, thus forming a certain indentation for initial positioning. Afterward, the rotating columns of multiple positioning clamping components can be rotated, causing the multiple mounting sleeves carrying adjustment rods to turn to the outer walls of the mold. Furthermore, the length of the adjusting rod can be adjusted according to the size of the mold. Then, the second limiting bolt is locked in the designated second limiting groove, thereby ensuring that the adjusting rod can contact the outer walls of the mold. When it is close to the outer walls of the mold, the first limiting bolt can be locked in the designated first limiting groove. Then, the threaded rods on the multiple positioning clamping components are rotated respectively, so that the threaded rods can drive the fixed post carrying the rubber sleeve to press against the outer wall of the mold, thereby positioning. The positioning point is the fixed post, which can form a point positioning clamp. Compared with clamping with clamping plates, this clamping method is often not limited by changes in shape and can still achieve the positioning effect. Moreover, the four-point clamping is more stable.

[0018] Furthermore, when it is necessary to replace the mold, multiple limit bolts can be loosened, and then the rotating column can be rotated away from the mold. Then, the electric push rod can be activated to drive the pressure plate to rise, so that the multiple universal ball components are on a horizontal plane. Then, the height of the external transport vehicle can be adjusted to be flush with the top of the fixed platform. Then, the mold can be slid to the top of the transport vehicle by sliding. Compared with manual handling, this handling method is simpler and less labor-intensive, reducing the labor intensity of personnel. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1-3 This utility model provides a technical solution:

[0027] A positioning fixture for processing plastic molds includes a fixed platform 100, a control switch 110 is provided on the side wall of the fixed platform 100, an electric push rod 120 is provided at the bottom of the inner cavity of the fixed platform 100, and a pressure plate 121 is connected to the output end of the electric push rod 120.

[0028] In some embodiments, the electric actuator 120 model can be Hebei Demai DWG, which is the prior art. The electric actuator 120 is electrically connected to the control switch 110.

[0029] The top of the fixed platform 100 is movably connected to a connecting rod 130, and the top of multiple connecting rods 130 is connected to a universal ball assembly 133. The top of the fixed platform 100 is also fixedly connected to multiple positioning clamping assemblies, each of which includes a fixed circular plate 200. The multiple fixed circular plates 200 are fixedly welded to the top of the fixed platform 100. The top of the multiple fixed circular plates 200 is provided with a limit groove 210. The top of the multiple fixed circular plates 200 is also rotatably connected to a rotating column 220. The outer circumference of the rotating column 220 is also fixedly connected to a connecting plate 230 and a mounting sleeve 240.

[0030] Specifically, multiple connecting rods 130 extend to the bottom of the fixed platform 100 and are connected to a connecting circular plate 131. A spring 132 is welded to the top of the connecting circular plate 131. The end of the spring 132 is connected to the top of the inner cavity of the fixed platform 100, which facilitates the adaptation and adjustment of the bottom shape of the mold to form a recessed area.

[0031] Furthermore, the connecting plate 230 has a threaded connection to a limit bolt 231, which matches the limit groove 210 to facilitate the limiting of the rotating column 220.

[0032] Furthermore, the top of the mounting sleeve 240 is threaded with a limit bolt 241, and an adjusting rod 250 is slidably connected inside the mounting sleeve 240. The top of the adjusting rod 250 is provided with a limit groove 251 that matches the limit bolt 241, so as to facilitate the fixing and limiting of the adjusting rod 250.

[0033] Furthermore, the outer wall of the adjusting rod 250 is threaded with a threaded rod 260, the end of the threaded rod 260 is rotatably connected to a mounting bracket 270, the inner wall of the mounting bracket 270 is fixedly connected to a fixing post 271, and the outer wall of the fixing post 271 is fitted with a rubber sleeve to facilitate clamping the outer walls of the mold.

[0034] It is worth noting that a guide rod 272 is also fixedly connected to the outer wall of the mounting bracket 270. The guide rod 272 is slidably connected to the top of the adjusting rod 250, which facilitates the guidance of the mounting bracket 270 and prevents the mounting bracket 270 from shifting when rotating.

[0035] In some embodiments, the device can be powered by an external power source.

[0036] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0037] Working Principle: In actual use, the bottom of more than 120 connecting circular plates 131 can be raised and pressed by the electric push rod. Then, the mold is placed on top of multiple universal ball components 133, and the position can be adjusted on the fixed platform. The entire adjustment process is more labor-saving. After adjusting to the appropriate position, the electric push rod 120 can drive the pressing plate 121 to descend, so that the multiple sleeve rods 130 can be compressed by the spring 132 to adapt to the shape of the bottom of the mold, thereby forming a certain indentation, which plays a preliminary positioning role. Then, the rotating column 220 of multiple positioning clamping components can be rotated, so that the multiple mounting sleeves 240 carrying adjusting rods 250 turn to the outer wall of the mold. The length of the adjusting rods 250 can be adjusted according to the size of the mold. Then, the second limit bolt 241 is locked in the designated limit groove 251, thereby ensuring that the adjusting rods 250 can contact the outer wall of the mold. When approaching the outer wall of the mold, the first limit bolt 231 can be locked in the designated... In the limiting groove 210, the threaded rods 260 on the multiple positioning clamping components are rotated respectively, so that the threaded rods 260 can drive the fixed post 271 carrying the rubber sleeve to press against the outer wall of the mold, thereby positioning. The positioning point is the fixed post 271, which can form a point positioning clamp. Compared with clamping with clamping plates, this clamping method is often not limited by changes in shape and can still achieve the positioning effect. Moreover, the four-point clamping is more stable. When the mold needs to be replaced, the multiple limiting bolts 231 can be loosened, and then the rotating column 220 can be rotated away from the periphery of the mold. Then, the electric push rod 120 is activated to drive the pressure plate 121 to rise, so that the multiple universal ball components 133 are on a horizontal plane. Then, the height of the external transport vehicle can be adjusted to be flush with the top of the fixed platform 100. Then, the mold is slid to the top of the transport vehicle by sliding. Compared with manual handling, this handling method is simpler and less labor-intensive, reducing the labor intensity of personnel.
