Description

Technical Field

[0001] The utility model relates to the technical field of insert mold structures, and specifically relates to a driving middle frame insert mold structure. Background Technique

[0002] The driving middle frame is a frame structure used to support and connect other components in a mechanical device or an electronic device. For example, the motor driving middle frame integrates a motor driving circuit to provide control signals and power output for the motor, and the gearbox middle frame contains a gearbox structure for adjusting the rotational speed and torque. When using a mold for injection molding of a driving middle frame product, inserts are often required. An insert is a special accessory used in mold design and manufacturing. It is embedded in the mold core (the working part of the mold). The use of inserts can improve the functionality and flexibility of the mold. For complex shapes that are difficult to directly machine, inserts can be used to simplify the machining process;

[0003] Molds for injection molding of driving middle frames often process different types of middle frame structures. Due to changes in product design or reallocation of the internal space of the mold, it may be necessary to adjust the length of the inclined guide pillar in the insert to adapt to the new core pulling distance. If it is necessary to change the magnitude of the core pulling force, it is usually also achieved by adjusting the length of the inclined guide pillar. A longer inclined guide pillar can provide a greater core pulling force. However, the inclined guide pillars in the current driving middle frame insert mold structure are basically of a fixed length. When encountering the above-mentioned working conditions where the length of the inclined guide pillar needs to be adjusted, only an inclined guide pillar that meets the length requirements can be re-machined, which is not conducive to improving the compatibility and expandability during the machining process of the insert mold structure. Content of the Utility Model

[0004] The purpose of the utility model is to provide a driving middle frame insert mold structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A driving middle frame insert mold structure includes a slider seat detachably and fixedly connected to the upper mold core of the mold body. One end of the slider seat is detachably installed and fixed with a slider member. Both ends of the slider seat are detachably fixed with pressing plates for fixing the slider seat. A wear-resistant block is detachably fixed to the outside of the slider seat. A lifter block is arranged on one side of the wear-resistant block. An inclined guide pillar is detachably inserted and fixed between the lifter block and the slider seat. The inclined guide pillar includes a positioning pillar, a threaded pillar is screwed at the bottom of the positioning pillar, and a movable pillar is rotatably connected to the bottom surface of the threaded pillar.

[0007] Furthermore: A plurality of bolts three are screwed between the slider seat and the slider member. A convex block is fixed at one end of the slider member, and a receiving groove is opened at one end of the slider seat.

[0008] Furthermore, a plurality of first bolts are screwed between the pressing plate and the mold body, and a fourth bolt is screwed between the slider seat and the mold body.

[0009] Furthermore, a plurality of limiting columns are detachably fixed between the shovel block and the slider seat, and a right-angled notch for placing the wear-resistant block is formed on the top surface of the slider seat.

[0010] Furthermore, a connecting column penetrating through the positioning column is fixed on the top surface of the threaded column, and a cross-shaped hole groove is formed on the top surface of the connecting column.

[0011] Furthermore, a threaded groove screwed with the threaded column is formed at the bottom end of the positioning column, and a plurality of sliding grooves are annularly and equiangularly formed on the outer side of the positioning column.

[0012] Furthermore, a plurality of sliding strips are annularly and equiangularly fixed on the top surface of the movable column, and the sliding strips are slidably connected with the corresponding sliding grooves.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By designing the inclined guide post such that a threaded column is screwed at the bottom end of the positioning column, and the bottom surface of the threaded column is rotatably connected with a movable column. When the overall length of the inclined guide post needs to be adjusted and lengthened due to product design changes or reallocation of the internal space of the mold, a cross-shaped screwdriver is used to rotate the connecting column. The connecting column drives the threaded column to rotate, causing the threaded column to screw and slide downward along the threaded groove at the bottom of the positioning column, so that the movable column gradually extends out of the positioning column, realizing the adjustment and lengthening of the overall length of the inclined guide post to meet the requirements of different product designs and changes, which is beneficial to improving the compatibility and expandability during the processing of the insert mold structure.

[0015] 2. By providing a right-angled notch on the top surface of the slider seat, during the installation of the wear-resistant block on the slider seat, the right-angled notch can play a role in limiting and supporting the wear-resistant block, preventing the other end of the wear-resistant block from swinging and shifting after a second bolt is screwed between one end of the wear-resistant block and the slider seat, facilitating both second bolts at both ends of the wear-resistant block to pass through the wear-resistant block and be accurately docked with the slider seat.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Example 1, please refer to Figures 1-6 , in the embodiment of the present utility model, a driving middle frame insert mold structure includes a slider seat 200 detachably and fixedly connected to the mold core 110 on the mold body 100. One end of the slider seat 200 is detachably installed and fixed with a slider part 210. Both ends of the slider seat 200 are detachably fixed with pressing plates 220 for fixing the slider seat 200. A wear-resistant block 230 is detachably fixed to the outside of the slider seat 200. A lifter block 240 is arranged on one side of the wear-resistant block 230. An inclined guide post 300 is detachably inserted and fixed between the lifter block 240 and the slider seat 200. The inclined guide post 300 includes a positioning post 310. The bottom of the positioning post 310 is screwed and connected with a threaded post 320. The bottom surface of the threaded post 320 is rotatably connected with a moving column 330.

[0025] Specifically, by setting the traditional lifter pin 300 with non-adjustable length into the form where a threaded post 320 is screwed and connected inside a positioning post 310, when it is necessary to adjust the overall length of the lifter pin 300 to be longer due to product design changes or reallocation of the internal space of the mold, rotate the connecting post 321 at the top of the positioning post 310 to make the connecting post 321 screw and move downward inside the threaded groove of the positioning post 310, so that the threaded post 320 drives the movable post 330 to move away from the positioning post 310, realizing the adjustment of the overall length of the lifter pin 300 to be longer, making the length of the lifter pin 300 on the insert mold structure adapt to different length requirements, which is beneficial to improving the compatibility and scalability during the processing of the insert mold structure.

[0026] As Figure 3 shown, in this embodiment, a plurality of bolts three 250 are screwed and connected between the slider base 200 and the slider member 210. A convex block is fixed at one end of the slider member 210, and a receiving groove 260 is formed at one end of the slider base 200. When installing the slider base 200 onto the slider member 210, the receiving groove 260 on the slider base 200 is snap-connected to the convex block on the slider member 210, and then the slider base 200 is screwed and installed onto the slider member 210 using the bolts three 250 on the slider base 200.

[0027] As Figure 3 shown, in this embodiment, a plurality of bolts one 221 are screwed and connected between the pressure plate 220 and the mold body 100, and a bolt four 270 is screwed and connected between the slider base 200 and the mold body 100.

[0028] In this embodiment, after installing the slider base 200 onto the slider member 210, the bolt four 270 can be screwed and connected again between the mold body 100 and the slider base 200 to firmly install and fix the slider base 200 onto the mold body 100. Then, place the pressure plates 220 at both ends of the slider base 200 respectively, and then use the bolts one 221 to fix the pressure plates 220 on the mold body 100. The pressure plates 220 can install and fix the slider base 200 on the mold body 100 from the ends of the slider base 200.

[0029] As Figure 4 shown, in this embodiment, a connecting post 321 penetrating the positioning post 310 is fixed on the top surface of the threaded post 320, and a cross-shaped hole groove is formed on the top surface of the connecting post 321. By using a cross-shaped screwdriver in the prior art, the connecting post 321 can be screwed to make the connecting post 321 drive the threaded post 320 to rotate, and further make the threaded post 320 move inside the positioning post 310.

[0030] As Figure 5 and Figure 6As shown, in this embodiment, a threaded groove for screwing connection with the threaded post 320 is provided at the bottom end of the positioning post 310. A plurality of sliding grooves 311 are equiangularly arranged in a ring shape on the outer side of the positioning post 310. A plurality of sliding bars 331 are fixedly arranged in a ring shape on the top surface of the movable post 330. The sliding bars 331 are slidably connected to the corresponding sliding grooves 311.

[0031] In this embodiment, the threaded groove enables the threaded post 320 to screw and move inside the positioning post 310. During the process of the movable post 330 sliding along the positioning post 310, the sliding bars 331 slide inside the sliding grooves 311. The sliding of the sliding bars 331 inside the sliding grooves 311 plays a role of guiding and limiting, enabling the movable post 330 to stably slide out along the threaded groove inside the positioning post 310.

[0032] During specific implementation, when it is necessary to adjust the length of the angled guide post 300 to be longer, rotate the connecting post 321 to make the threaded post 320 rotate. The threaded post 320 screws and moves downward inside the threaded groove of the positioning post 310, so that the threaded post 320 drives the movable post 330 to move downward together, making the overall length of the angled guide post 300 longer. On the contrary, when it is necessary to adjust and shorten the length of the angled guide post 300 that has been adjusted to be longer, the connecting post 321 can be rotated in the reverse direction to make the threaded post 320 screw and move upward in the reverse direction inside the threaded groove of the positioning post 310, so that the threaded post 320 drives the movable post 330 to move into the positioning post 310, realizing the shortening of the entire length of the angled guide post 300.

[0033] Embodiment 2, on the basis of Embodiment 1, in order to have a structure for supporting and limiting the wear-resistant block 230 during the installation of the insert mold structure.

[0034] As Figure 3 shown, in this embodiment, a plurality of limit posts 241 are detachably fixed between the lifter block 240 and the slider base 200. A right-angled notch 280 for placing the wear-resistant block 230 is provided on the top surface of the slider base 200. The lifter block 240 is mainly limited and fixed on the slider base 200 through the angled guide post 300. The two limit posts 241 play a role in restricting the position of the lifter block 240. The right-angled notch 280 is convenient for limiting and supporting the wear-resistant block 230 when installing the wear-resistant block 230. The wear-resistant block 230 is fixedly attached to the slider base 200 through the bolt two 231.
