Description

Technical Field

[0001] This utility model relates to the field of injection molding technology for conveyor chain plates, and in particular to a tooling for mounting inserts on a machine. Background Technology

[0002] In the field of conveying equipment, chain conveyor systems are widely used in industries such as food, pharmaceuticals, and electronics due to their stable conveying and high load-bearing capacity. Some chain conveyors require roller inserts to be installed in the mold before injection molding. Workers first install the inserts one by one onto the mold, and then close the mold to inject the chain conveyor body. Therefore, on the one hand, installing inserts one by one is inefficient; on the other hand, due to the high temperature of the mold, workers are prone to burns when handling individual inserts for installation.

Detailed Implementation

[0013] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0014] First, combine Figures 1-9 The present invention describes an insert mounting fixture according to an embodiment of the present invention, which is used to quickly install inserts into molds and has a wide range of applications.

[0015] like Figures 2-9 As shown, the insert mounting fixture of this utility model embodiment includes: The fixed base 1 is provided with a first limiting groove 11, a plurality of second limiting grooves 12, and a plurality of third limiting grooves 13; Pressing member 2 is movably disposed within the first limiting groove 11 and can move linearly within the first limiting groove 11; The pressing component 2 is provided with a pair of first positioning holes 21 and several ejector pins 22; A pair of screws 3 are respectively set in a pair of first positioning holes 21, passing through the first positioning holes 21 and threadedly connected to the fixed seat 1. The pressing member 2 can move along the axis of the screws 3. A return spring 4 is fitted on the screw 3 for pressing the reset of the component 2; Several second limiting grooves 12 are used to place inserts 5; Several third limiting grooves 13 correspond one-to-one with several second limiting grooves 12 and are connected to the second limiting grooves 12; Several ejector posts 22 are located in several third limiting grooves 13 respectively. Pressing the pressing member 2 can eject the insert 5 in the corresponding second limiting groove 12.

[0016] Furthermore, such as Figures 5-6 As shown, in this embodiment, the fixing seat 1 is provided with a pair of threaded holes 14, and a pair of screws 3 are respectively threadedly connected to the fixing seat 1 through the pair of threaded holes 14, so that the fixing seat 1 and the screws 3 are relatively fixed.

[0017] Furthermore, such as Figure 4 , 9 As shown, in this embodiment, a pair of fourth limiting grooves 121 are symmetrically arranged on both sides of the second limiting groove 12. The fourth limiting grooves 121 are connected to the second limiting groove 12. When the insert 5 is placed into the second limiting groove 12, the rotating shafts 51 on both sides of the insert 5 are respectively interference-fitted with the pair of fourth limiting grooves 121 to prevent the insert 5 from falling off when the fixed seat 1 is lifted.

[0018] Furthermore, such as Figure 7 As shown, in this embodiment, the fixing base 1 is provided with a first hollow opening 15, and the pressing member 2 is provided with a second hollow opening 23. The first hollow opening 15 and the second hollow opening 23 cooperate to facilitate the worker to pick up the fixing base 1 and to facilitate pressing the pressing member 2.

[0019] Furthermore, such as Figures 5-6 As shown, in this embodiment, an annular limiting step 211 is provided in the first positioning hole 21, and the reset spring 4 is provided between the rear end of the annular limiting step 211 and the fixed seat 1.

[0020] Furthermore, such as Figures 5-6 As shown, in this embodiment, a washer 31 is fitted on the screw 3, and the washer 31 is located at the front end of the annular limiting step 211.

[0021] Furthermore, such as Figure 6As shown, in this embodiment, the surface of the ejector post 22 that contacts the insert 5 is an arc-shaped surface, which is coupled with the insert 5 to facilitate ejecting the insert 5.

[0022] Working principle: Mold 6 is preheated. During this process, the worker places the inserts 5 one by one into the second limiting groove 12 on the fixed seat 1. The rotating shaft 51 of the insert 5 is interference-fitted with the corresponding fourth limiting groove 121 to prevent the insert 5 from easily falling out of the second limiting groove 12. After the mold 6 is preheated, the mold is opened. The worker's hand reaches into the first cutout 15 and the second cutout 23 to pick up the fixed seat 1, aligns the insert 5 on the fixed seat 1 with the insert 5 mounting groove 61 on the mold 6, and presses the pressing member 2 so that the ejector pin 22 on the pressing member 2 moves towards the insert 5 until the insert 5 is ejected and embedded into the mounting groove 61 on the mold 6. During this process, the pressing member 2 moves towards the insert 5 along the axis of the screw 3, and the return spring 4 is compressed under the action of the annular limiting step 211. The pressing member 2 is released, and the pressing member 2 returns to its original position under the action of the return spring 4. Then, the mold is closed for injection molding. During the injection molding process, the worker can continue to install the insert 5 on the fixed seat 1.

[0023] Above, refer to Figures 1-9 The present invention describes an insert mounting fixture according to an embodiment of the present invention, which can install multiple inserts 5 on an injection mold 6 at one time, thereby shortening the injection waiting time, improving injection efficiency, and reducing the risk of worker injury.
