Description

Technical Field

[0001] This application relates to the field of plastic injection molding equipment, and in particular to a feeding mechanism for optical injection molded parts. Background Technology

[0002] Injection molding hot cutting is a technology that automatically separates the plastic sprue from the finished product during the injection molding process. In the process of integral molding of injection molded parts, to improve molding efficiency and reduce unnecessary operations, multiple injection molded parts of the same shape are often molded as a single piece, and then hot cutting technology is used to separate the individual injection molded parts. Currently, injection molding hot cutting mechanisms on the market are mainly divided into two types according to the cutting method: internal cutting and external cutting.

[0003] Existing injection molding feeding mechanisms typically only support a single feeding method. For injection molded parts with special shapes or uneven surface textures, using a single feeding method can not only damage the injection molded part itself, but also fail to prevent structural damage to relatively weak areas of the part during hot cutting. Utility Model Content

A bidirectional cylinder is slidably connected to each of the two mounting slots. A slide block is connected to the end of each bidirectional cylinder away from the strip plate. A sliding groove is formed along the length of the side of the slide block away from the bidirectional cylinder. Two clamping rods are symmetrically slidably arranged in the sliding groove, and both clamping rods are drively connected to the bidirectional cylinder.

[0007] Optionally, the two clamping rods are provided with anti-slip textures on the sides of their proximity to each other to prevent the injection molded part from detaching from the feeding mechanism.

[0009] Optionally, the driving member is a rodless cylinder, and a sliding block on the driving member is fixedly connected with the fixing seat.

[0010] Optionally, an elastic rubber sleeve is sleeved on a sliding rod of the driving member and between the mounting platform and the sliding block.

DETAILED DESCRIPTION

[0020] The following will be described in detail in combination with the accompanying drawings. Figures 1-4Further details of the application are described below.

[0021] The embodiment of the application discloses an optical injection molding part feeding mechanism.

[0022] With reference to Figure 1 An optical injection molding part feeding mechanism is installed in a hot cutting machine and used for feeding in the hot cutting operation of injection molding parts. The feeding mechanism comprises a mounting frame 1 arranged in the vertical direction, a driving part 2 fixedly arranged on the mounting frame 1 and a fixed seat 3 fixedly connected with the driving part 2. The driving part 2 is used for driving the injection molding parts to move up and down, so as to realize clamping and feeding.

[0023] With reference to Figure 2 Further, the fixed seat 3 is provided with a strip-shaped plate 4 arranged in the horizontal direction, and two mounting grooves 41 are symmetrically arranged on the side of the strip-shaped plate 4 away from the fixed seat 3. The two mounting grooves 41 are respectively communicated with the two sides of the strip-shaped plate 4 along the length direction, and a bidirectional cylinder 42 is slidably connected in each mounting groove 41. The bidirectional cylinder 42 is connected with a sliding seat 5 at the end away from the strip-shaped plate 4, and a sliding groove 51 is arranged on the sliding seat 5. Two clamping rods 6 which are in transmission connection with the bidirectional cylinder 42 are symmetrically arranged in the sliding groove 51, and are used for clamping the injection molding parts to be cut.

[0024] The structure is designed so that the feeding mechanism can clamp two injection molding parts at a time, thereby improving the feeding and feeding efficiency.

[0025] It should be noted that the position of the bidirectional cylinder 42 in the mounting groove 41 can be changed, that is, the distance between the two bidirectional cylinders 42 can be changed according to actual needs.

[0026] With reference to Figure 2 The two clamping rods 6 arranged on the same bidirectional cylinder 42 are provided with anti-skid lines 6231 on the side close to each other, which are used for preventing the injection molding parts from separating from the clamping rods 6 due to too high movement speed when the feeding mechanism clamps the injection molding parts, and preventing danger.

[0027] With reference to Figure 1 and Figure 2 A rotating seat 7 is arranged between the fixed seat 3 and the strip-shaped plate 4, and the power output end of the rotating seat 7 is fixedly connected with the geometric center of the strip-shaped plate 4. When it is needed to rotate the injection molding parts to increase the contact area between the injection molding parts and the cutting platform, so as to avoid the structure of the injection molding parts from being extruded and damaged, the rotating seat 7 can easily realize the overturning of the injection molding parts, and the operation is simple, and the rotating seat 7 plays a role in protecting the structural integrity of the injection molding parts.

[0028] The geometric center of the rotating seat 7 is arranged at the geometric center of the strip-shaped plate 4, so that the injection molding parts are uniformly stressed when rotating, and position deviation caused by centrifugal force is avoided.

[0029] Referring to Figure 1 and Figure 2 The driving member 2 is a rodless cylinder, and the sliding block on the driving member 2 is fixedly connected with the fixed seat 3, so that the installation and rotation of the strip-shaped plate 4 are not affected.

[0030] Referring to Figure 1 and Figure 3 Preferably, an elastic rubber sleeve 8 is sleeved on the sliding rod of the driving member 2 between the sliding block and the bottom of the driving member 2, so as to avoid the collision between the injection molding part and the mechanism installation platform when the driving member 2 fails, play an emergency protection role, and improve the safety of the mechanism operation.

[0031] Referring to Figure 4 The clamping rod 6 comprises a connecting portion 61 and a clamping portion 62 which are detachably connected, and this design is to facilitate replacement of the clamping portion 62 according to different injection molding parts, improve the practicability of the mechanism as a whole, and expand the application range. Specifically, the connecting portion 61 is slidingly arranged in the sliding groove 51, and two connecting holes 611 for screwing the clamping portion 62 are formed at one end of the connecting portion 61 away from the sliding groove 51.

[0032] The clamping portion 62 comprises a first rod 621, a second rod 622 and a third rod 623 which are integrally connected in space and connected with each other perpendicularly. The first rod 621 is provided with two mounting holes 6211 corresponding to the connecting holes 611, and the anti-skid lines 6231 are arranged on the third rod 623. The clamping portion 62 is designed in this structure to prevent the injection molding part from colliding with other structures on the mechanism.

[0033] Preferably, a sensor for monitoring the position of the sliding block is connected to the driving member 2, so as to facilitate feeding according to the real-time state of the hot cutting machine and improve the intelligence of the mechanism. Since the sensor is an electronic component and has a small size, it is not shown in the drawings of the present application.

[0034] The implementation principle of the optical injection molding part feeding mechanism according to the embodiment of the present application is as follows:

[0035] First, the two clamping rods 6 are driven by the bidirectional cylinder 42 to clamp the injection molding parts, and the operation of simultaneously feeding two injection molding parts is completed.

[0036] Then, the injection molding parts are rotated by the rotating seat 7, so as to increase the contact area with the cutting platform and protect the integrity of the fragile structures on the injection molding parts.

[0037] Then, the injection molding parts are sent to the feeding station by the up-down movement of the driving member 2, and the automatic feeding operation is completed.

[0038] The above are preferred embodiments of the present application, but do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
