In the related art, there are generally two molding cores, which are divided into a main core and a sub-core. The main core and the auxiliary core are respectively connected with a connecting sliding block. When the core is pulled, the inclined guide post on the fixed die is matched with the connecting sliding block, so that the connector protecting sleeve formed by separating the main core from the auxiliary core is realized. Because the length of the main core is larger than that of the auxiliary core, the situation of blocking easily occurs in the core pulling process, the core pulling failure is caused, and the connector protective sleeve blanking is further affected. The core pulling device is matched with the second core pulling assembly through the first core pulling assembly, the main core and the auxiliary core can be smoothly pulled out from the connector protecting sleeve after molding, the blocking condition can not occur, and the connector protecting sleeve can be effectively ensured to be capable of smoothly discharging.

Referring to fig. 1, fig. 2, and fig. 3, fig. 1 is an exploded view of a core-pulling device according to an embodiment of the present disclosure; FIG. 2 is a top view of a core pulling device according to an embodiment of the present disclosure; FIG. 3 is a cross-sectional view taken along the direction A-A in FIG. 2; the embodiment of the application provides a core pulling device for a connector protective sleeve, which comprises a fixed die 100, a movable die 200, a first core pulling component 300 and a second core pulling component 400.

Illustratively, the movable mold 200 is movable relative to the fixed mold 100, and when the movable mold 200 moves downward, portions of the first core back assembly 300 and the second core back assembly 400 move downward with the movable mold 200. The second connecting slider of the second core-pulling assembly 400 moves forward under the cooperation of the inclined guide post arranged on the movable die 200, so that the auxiliary core is pulled out from the formed connector protecting sleeve. Subsequently, the power source of the first core pulling assembly 300 drives the main core to move backwards, and the main core is pulled out of the formed connector protecting sleeve, so that the main core and the auxiliary core are effectively and rapidly pulled out of the connector protecting sleeve, and the blanking efficiency of the connector protecting sleeve is improved.

The first core-pulling assembly 300 comprises a power source 310 and a plurality of main cores 320, wherein the power source 310 is arranged on the movable mould 200, the power source 310 is connected with the main cores 320 to drive the main cores 320 to be pulled out from the formed connector protective sleeve, and the plurality of main cores 320 are arranged at intervals; the second core pulling assembly 400 comprises an inclined guide pillar 410, a second connecting sliding block 420 and a plurality of auxiliary cores 430, wherein the inclined guide pillar 410 is arranged on the fixed die 100, the second connecting sliding block is slidably arranged on the movable die, the second connecting sliding block 420 is connected with the plurality of auxiliary cores 430, and the second connecting sliding block 420 is slidably matched with the inclined guide pillar 410 to drive the auxiliary cores 430 to be pulled out from the formed connector protective sleeve; the main core 320 is disposed opposite to the sub core 430, and the extraction direction of the main core 320 is opposite to the extraction direction of the sub core 430.

Specifically, the number of the main cores 320 is not particularly limited, and may be one, two, three, four, or more. In the present embodiment, the number of primary cores 320 is four.

The number of sub-cores 430 is not particularly limited and may be one, two, three, four or more. In the present embodiment, the number of sub-cores 430 is four.

In the molding, the end of the main core 320 is butted with the end of the sub-core 430 to form a core.

In addition, since the length of the main core 320 is greater than that of the sub-core 430, the main core 320 has a longer moving path than the sub-core 430 when being withdrawn. Therefore, the primary core-pulling assembly 300 drives the primary core 320 to move backward by providing the power source 310, thereby efficiently and rapidly achieving the extraction of the primary core 320.

In addition, the power source 310 is an oil cylinder.

In some examples, as shown in fig. 1 to 3, the first core-pulling assembly 300 further includes a first connection slider 330 and a first insert block 340, wherein the first connection slider 330 is movably disposed on the movable mold 200, one end of the first connection slider 330 is connected to the power source 310, the first insert block 340 is disposed at the other end of the first connection slider 330, and the plurality of main cores 320 are disposed on the first connection slider 330 at intervals from each other and protrude from the first insert block 340.

Specifically, in order to control the plurality of main cores 320 to simultaneously move backward, the plurality of main cores 320 are connected to the first connecting slider 330, so that the plurality of main cores 320 are synchronously moved.

The first insert 340 functions to reinforce the main core 320.

In some examples, as shown in fig. 1 to 3, a first guide rail (not shown) is provided on the moving die 200, and a first sliding groove slidingly engaged with the first guide rail is provided on the first connecting slider 330.

Specifically, through the first guide rail and the first chute mutually cooperating, the first connecting sliding block 330 is realized to move along the first guide rail, so that the main core 320 can loose core according to the set direction, the deviation condition can not occur, and the quality of the connector protecting sleeve is ensured.

In some examples, as shown in fig. 1 to 3, the first connecting slider 330 is provided with a clamping groove 331 that is in clamping fit with the power source 310.

Specifically, in order to enhance the connection stability between the first connection slider 330 and the power source 310, the first connection slider 330 can move smoothly, so that the first connection slider 330 is provided with a clamping slot 331 that is matched with the power source 310.

In some examples, as shown in fig. 1 to 3, the second connecting slider 420 is provided with an inclined hole 421 that mates with the inclined guide pillar 410.

Specifically, in order to achieve a sliding fit with the second connecting slider 420 through the oblique guide pillar 410, an oblique hole 421 is provided on the second connecting slider 420. When the movable mold 200 moves downward, the second connecting slider 420 also moves downward, and at this time, the inclined guide pillar 410 gradually leaves the inclined hole 421, and the second connecting slider 420 gradually moves forward under the cooperation of the inclined guide pillar 410 and the inclined hole 421, so as to draw the secondary core 430 away.

In some examples, as shown in fig. 1 to 3, a second guide rail (not shown) is provided on the moving mold 200, and a second sliding groove slidingly engaged with the second guide rail is provided on the second connecting slider 420.

Specifically, through the cooperation of the second guide rail and the second sliding groove, the second connecting sliding block 420 is moved along the second guide rail, so that the auxiliary core 430 can loose core according to the set direction, the deviation condition can not occur, and the quality of the connector protecting sleeve is ensured.
