Description

Technical Field

[0001] The utility model relates to the technical field of shoe injection molding, in particular to a toe cap sole molding injection molding device. Background Art

[0002] In the prior art, the sole is usually made by injection molding. After the bottom film groove is poured with injection molding liquid, the shoe body is put on the shoe last, and the shoe last is fixed on an external driving device. The shoe body is driven downward by the driving device so that the insole of the shoe body enters the bottom film groove, and then the injection molding liquid is formed into a sole and connected to the bottom of the shoe body through subsequent heat treatment. However, in the prior art, the operator usually places the shoe body directly on the bottom film groove. During the injection molding process of the shoe body, the shoe body is easily affected by external stress and shakes or deviates. In particular, the weight of the closed-toe shoe is heavy, so that the toe of the shoe body will sink slightly during injection molding, thereby affecting the injection molding accuracy of the sole. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a closed-toe shoe sole molding injection molding device to solve the problem that the closed-toe shoe sole injection molding device in the prior art lacks the function of fixing the closed-toe shoe toe.

[0004] The shoe sole of the embodiment of the present invention is a shoe sole forming injection molding device, comprising a base, the base is provided with a bottom film groove for external injection molding liquid to be perfused, the rear end of the base is swingably provided with a left clamping arm and a right clamping arm, the end of the left clamping arm is hingedly arranged with the end of the right clamping arm, the inner wall of the left clamping arm and the inner wall of the right clamping arm are both provided with notches, the two notches are combined to form a clamping groove for clamping the shoe body to be processed when the left clamping arm and the right clamping arm are gathered together, and the two notches are combined to form a clamping groove for clamping the shoe body to be processed when the left clamping arm and the right clamping arm are gathered together. The front end of the base is provided with a fixing block, the bottom surface of the fixing block is provided with a receiving groove for accommodating the head of the shoe bag to be processed by the outside, and the fixing block is provided with a plurality of sliding holes corresponding to the position of the receiving groove, and the plurality of sliding holes are connected to the receiving groove, and each of the sliding holes is provided with an adsorption member for adsorbing the outer wall of the head of the shoe bag to be processed by the outside and a driving member for cooperating with the adsorption member to apply a force to the head of the shoe bag to be processed by the outside so that the outer wall of the head of the shoe bag is abutted and matched with the inner peripheral wall of the receiving groove.

[0005] The advantages of adopting the above technical scheme are as follows: the operator first pours the injection liquid into the bottom film groove, and after the operator drives the external shoe body to be processed downward through the external driving device and makes the inner sole of the shoe body enter the bottom film groove, the operator swings the left clamp arm and the right clamp arm to make the two gather together and fix the shoe body of the processed shoe. At this time, the head of the processed shoe bag is engaged with the receiving groove. The operator absorbs the outer wall of the head of the shoe bag through the adsorption part and applies a force to the head of the bag through the driving part so that the outer wall of the head of the bag is abutted with the inner wall of the receiving groove, thereby fixing the head of the bag in the receiving groove. At the same time, the setting of the adsorption part and the driving part is used to prevent the head of the bag from sinking, thereby preventing the toe of the processed shoe from sinking and affecting the injection molding accuracy of the sole.

[0006] The utility model is further arranged that: an adsorption tube is slidably arranged in each of the sliding holes, a negative pressure hole is passed through the hollow of the adsorption tube, the starting end of the adsorption tube is an adsorption end connected to the negative pressure hole, the adsorption component includes a small vacuum generator, the small vacuum generator is arranged at the end of the adsorption tube and the suction end of the small vacuum generator is connected to the negative pressure hole, a push rod is arranged on the outer wall of the small vacuum generator, the end of the push rod is a pushing end for passing through the sliding hole and being pushed by an external operator, and the adsorption end is arranged close to the position of the containing groove.

[0007] The benefits of adopting the above technical solution are: when it is necessary to adsorb the head part of the shoe bag, the operator presses down the push rod so that the push rod drives the small vacuum generator to press down, and the small vacuum generator is arranged at the end of the adsorption tube, so that the small vacuum generator drives the adsorption tube to press down, so that the adsorption end of the adsorption tube contacts the outer wall of the head part of the shoe bag. At this time, the operator starts the small vacuum generator, and the small vacuum generator causes the negative pressure hole to form a negative pressure, thereby realizing the adsorption of the head part of the shoe bag by the adsorption end of the adsorption tube. The fixed limit of the head part of the shoe bag is achieved through the combination of the adsorption tube and the small vacuum generator, so as to avoid the sinking of the head part of the shoe bag, and then avoid the sinking of the toe part of the shoe bag to affect the injection molding accuracy of the sole; the small vacuum generator in the above technology is a prior art, which is used to generate vacuum and negative pressure. Because it is a prior art, its connection method with the adsorption tube and its own structure and function will not be described in detail.

[0008] The utility model is further configured that: a telescopic spring is connected between the outer peripheral wall of the push rod and the inner peripheral wall of the sliding hole, and the telescopic spring is the driving member.

[0009] The advantages of adopting the above technical solution are as follows: when the push rod is pressed down in the sliding hole by the thrust applied by the operator, the telescopic spring is stretched and deformed; when the push rod is not subjected to the thrust applied by the operator, the telescopic spring is deformed and reset, and the generated force will be applied to the push rod, thereby driving the push rod to move upward, and the adsorption tube has generated an adsorption force on the head part at its adsorption end, so the upward movement of the push rod will drive the adsorption tube to move upward, that is, drive the head part of the bag upward so that the outer wall of the head part is stably attached to the inner wall of the groove and is always subjected to the force in the direction of the inner wall of the groove, thereby avoiding the head part of the bag from sinking, and further avoiding the sinking of the toe of the processed shoes, which affects the injection molding accuracy of the sole.

[0010] The utility model is further configured as follows: two limit grooves are provided on the inner circumferential wall of the sliding hole along the axial direction of the sliding hole, the two limit grooves are arranged opposite to each other, and limit blocks are arranged on the outer circumferential wall of the adsorption tube corresponding to the two limit grooves, the two limit blocks are respectively slidably arranged in their respective corresponding limit grooves, the radial cross-section of the limit block is square, and the radial cross-section of the limit block and the radial cross-section of the limit groove are adapted to each other.

[0011] The benefit of adopting the above technical solution is that the cooperation between the limit block and the limit groove can prevent the adsorption tube from escaping from the limit groove along the axis direction of the sliding hole, thereby preventing the adsorption tube from sliding out of the sliding hole due to the influence of the telescopic spring, resulting in adsorption failure.

[0012] The utility model is further configured that: the inner wall of the left clamp arm and the inner wall of the right clamp arm are both embedded with adsorption blocks, and the two adsorption blocks are both made of magnetic material.

[0013] The benefit of adopting the above technical solution is that after the left clamp arm and the right clamp arm are gathered together to clamp the processed shoe body, the two adsorption blocks cooperate with each other magnetically, so that the left clamp arm and the right clamp arm are stably connected to achieve clamping and limiting of the processed shoe body.
