According to an embodiment of the present disclosure, there is provided an injection mold, as shown in fig. 1 to 8, including an upper mold body 1 and a lower mold body 2.
The upper die body 1 is provided with a first die cavity 10, and a first elastic part 11 is arranged in the first die cavity 10.
The lower die body 2 is provided with a second die cavity 20, and a second elastic piece 21 is arranged in the second die cavity 20.
In the clamped state, the first elastic element 11 and the second elastic element 21 serve to support the insert 3.
In this embodiment, the upper mold body 1 and the lower mold body 2 form a main structure, and the upper mold body 1 and the lower mold body 2 move relatively to each other to lock or separate the first mold cavity 10 and the second mold cavity 20. In the closed position, the first and second mold cavities 10 and 20 snap together to form a complete mold cavity. An insert 3 for forming a product is disposed in the cavity so that the injection molding material 5 wraps around the insert 3.
For example, when the mold is closed, the lower mold body 2 is kept stationary, and the insert 3 is set in the second cavity 20. The upper mold body 1 is positioned above the lower mold body 2 and moves downward. The upper mold body 1 is fastened to the lower mold body 2, so that the first mold cavity 10 and the second mold cavity 20 form a mold cavity.
The first elastic member 11 is disposed in the first cavity 10, the second elastic member 21 is disposed in the second cavity 20, and in a clamped state, the first elastic member 11 and the second elastic member 21 are supported from both sides of the insert 3. For example, the first elastic member 11 is supported from above the insert 3, and the second elastic member 21 is supported from below the insert 3. When placing the insert 3 in the second cavity 20, the insert 3 is placed on the second resilient member 21.
The first elastic member 11 has elasticity to provide a compression space at an upper side of the insert 3, and the second elastic member 21 has elasticity to provide a compression space at a lower side of the insert 3. After the injection molding material 5 enters, when the insert 3 has different side pressure differences, the first elastic element 11 or the second elastic element 21 forms a buffer to prevent the insert 3 from being subjected to unbalanced pressure. Under the condition that the stress of the insert 3 is balanced, the damage of the insert 3 is effectively avoided. For example, when the lower side pressure of the insert 3 is smaller than the upper side pressure, the insert 3 is subjected to a downward force, and the second elastic member 21 is compressed downward to form a cushioning effect.
Due to the clamping effect of the first elastic member 11 and the second elastic member 21 on the insert 3, when the insert 3 is subjected to uneven pressure in the horizontal direction, buffering can be formed by the first elastic member 11 and the second elastic member 21.
The elastic characteristics of the first elastic member 11 and the second elastic member 21 can buffer the pressure applied to the insert 3 in different directions, thereby effectively protecting the insert 3 from being damaged.
Alternatively, the first elastic member 11 and/or the second elastic member 21 may be: one of a rubber member, a spring, and a metal sheet. The insert 3 is a ceramic piece. The injection molding material 5 is plastic.
In one embodiment, the first elastic member 11 is disposed obliquely, and the second elastic member 21 is disposed obliquely.
In this embodiment, the obliquely arranged first spring 11 forms a support on the upper side of the insert 3 and the obliquely arranged second spring 21 forms a support on the lower side of the insert 3. The component force of the elastic force when the first elastic member 11 and the second elastic member 21 are extended and contracted can provide the elastic force in the horizontal direction. When the insert 3 is subjected to a pressure in the horizontal direction, the inclined first elastic member 11 and the second elastic member 21 cushion the pressure in the horizontal direction. This further dampens the pressure in the horizontal direction and protects the insert 3 from damage.
For example, the first elastic member 11 and the second elastic member 21 are inclined in the same direction and at the same angle, so that the first elastic member 11 and the second elastic member 21 form uniform support on both sides of the insert 3, thereby providing uniform cushioning force.
In one embodiment, as shown in fig. 1 to 8, the first elastic member 11 includes a first spring 111 and a first support member 112, the first spring 111 is connected in the first mold cavity 10, and the first support member 112 is connected to the first spring 111.
The second elastic member 21 includes a second spring 211 and a second support 212, the second spring 211 is connected in the second cavity 20, and the second support 212 is connected with the second spring 211.
In this embodiment, the first elastic member 11 is made elastic by the first spring 111, and the first support member 112 is used to abut against the insert 3 to support the insert 3. The second spring 211 gives the second elastic member 21 elasticity, and the second support member 212 is used for abutting against the insert 3 to support the insert 3.
The first spring 111 can stably cushion the force received by the insert 3 toward the first cavity 10 side, and the second spring 211 can stably cushion the force received by the insert 3 toward the second cavity 20 side.
The first and second supports 112 and 212 support the insert 3 and rub the insert 3 in the horizontal direction, thereby transmitting an unbalanced pressure in the horizontal direction to the first and second springs 111 and 211 to form a buffer.
For example, the contraction directions of the first and second springs 111 and 211 are arranged in the vertical direction. The forces in different directions applied to the insert 3 correspond to forces in one horizontal direction and one vertical direction. Therefore, the first spring 111 and the second spring 211 can effectively buffer the forces of the insert 3 in different directions, so as to protect the insert 3 from being damaged.
In one embodiment, as shown in fig. 1-8, the first support 112 includes a first block having a first mounting groove in which the first spring 111 is coupled.
In one embodiment, as shown in fig. 1-8, the first spring 111 is inserted into a first mounting groove, and the first mounting groove forms a stable restriction for the first spring 111, so that the first spring 111 and the first block form a firm connection. The second spring 211 is inserted into the second mounting groove, and the second mounting groove stably limits the second spring 211, so that the second spring 211 and the second block form a firm connection.
In one embodiment, as shown in fig. 1-8, the insert 3 is provided with positioning holes 31 matching with the positioning members 213.
In a mold closing state, the positioning member 213 is inserted into the positioning hole 31, and a buffer gap is formed between the positioning member 213 and a hole wall of the positioning hole 31.
In this embodiment, the positioning is formed by the positioning member 213 and the positioning hole 31 so that the insert 3 can be stably placed on the second elastic member 21.
The cushion gap between the positioning member 213 and the hole wall of the positioning hole 31 enables the insert 3 to be displaced in the horizontal direction. The surfaces of the second block and the first block are in contact with the insert 3, and the pressure of the insert 3 in the horizontal direction can form friction force. The friction fit buffer gap can further play a role in buffering in the horizontal direction, thereby improving the reliability of the horizontal pressure to which the buffer insert 3 is subjected.
In one embodiment, as shown in fig. 1-8, the positioning member 213 is a pin structure.
The size of the pin structure gradually changes from one end to the other end to form a structure with one end being large in size and the other end being large in size. The positioning member 213 is more easily positioned in the positioning hole 31 by fitting the smaller-sized end of the pin structure into the positioning hole 31.
In one embodiment, a first receiving groove is formed in the first mold cavity 10, and the first spring 111 is connected to the first receiving groove.
A second accommodating groove is formed in the second cavity 20, and the second spring 211 is connected to the second accommodating groove.
In this embodiment, the first spring 111 forms a connection in the first receiving groove, and the second spring 211 forms a connection in the second receiving groove. When the insert 3 is subjected to an unbalanced pressure, the first spring 111 can be contracted along the first receiving groove or the second spring 211 can be contracted along the second spring 211.
The first receiving groove makes the contraction process of the first spring 111 more stable, and the second receiving groove makes the contraction process of the second spring 211 more stable.
Optionally, at least a part of the structure of the first supporting member is embedded in the first receiving groove, and at least a part of the structure of the second supporting member is embedded in the second receiving groove.
The first supporting member 112 forms a shielding part for the first accommodating groove at the notch position of the first accommodating groove, so that the injection molding material 5 is prevented from entering the first accommodating groove to affect the expansion and contraction of the first spring 111. And the injection molding material 5 entering the first accommodating groove is prevented from increasing the demolding difficulty. In addition, a part of the structure of the first supporting member 112 is embedded into the first receiving groove, so that the first supporting member 112 is more easily shrunk into the first receiving groove when being pressed, thereby preventing the inner wall of the first mold cavity 10 from influencing the first supporting member 112 to enter the first receiving groove, and improving the reliability of buffering.
The second supporting member 212 forms a shielding part for the second accommodating groove at the notch position of the second accommodating groove, so that the injection molding material 5 is prevented from entering the second accommodating groove to affect the extension and contraction of the second spring 211. And the injection molding material 5 entering the second accommodating groove is prevented from increasing the demolding difficulty. In addition, a part of the structure of the second supporting member 212 is embedded into the second receiving groove, so that the second supporting member 212 is more easily shrunk into the second receiving groove when being pressed, the influence of the inner wall of the second mold cavity 20 on the second supporting member 212 entering the second receiving groove is avoided, and the buffering reliability is improved.
In one embodiment, as shown in fig. 1 to 8, at least two first elastic members 11 are disposed in the first mold cavity 10, and at least two second elastic members 21 are disposed in the second mold cavity 20.
The at least two first elastic members 11 and the at least two second elastic members 21 can form a more stable support for the insert 3, so that the insert 3 is clamped between the at least two first elastic members 11 and the at least two second elastic members 21.
Optionally, each of the at least two first elastic members 11 has a different inclination direction, and the plurality of first elastic members 11 are distributed in an array in the first mold cavity 10. Each of the at least two second elastic members 21 has a different inclination direction, and the plurality of second elastic members 21 are arranged in an array in the second cavity 20. This enables a more uniform cushioning to be formed on the upper and lower sides of the insert 3.
For example, at least two first resilient members 11 are distributed around the center of the first mold cavity 10, each first resilient member 11 being gradually distant from or close to the center of the first mold cavity 10 from the end connected to the first mold cavity 10 to the end supporting the insert 3. For example, the center of the first mold cavity 10 is the longitudinal axis of the first mold cavity 10. At least two second elastic members 21 are distributed around the center of the second cavity 20, each second elastic member 21 being gradually distant from or close to the center of the second cavity 20 from the end connected to the second cavity 20 to the end supporting the insert 3. For example, the center of the second mold cavity 20 is the longitudinal axis of the second mold cavity 20.
The first elastic piece 11 and the second elastic piece 21 form uniform and stable support for the insert 3, and the buffering effect is improved.
In one embodiment, as shown in fig. 1 to 8, the upper mold body 1 is provided with an injection molding conduit 4, and the injection molding conduit 4 is communicated with the first mold cavity 10.
In this embodiment, the injection molding material 5 is injected through the injection molding duct 4 of the upper mold body 1. For example, the upper mold body 1 is moved to a position above the lower mold body 2 to mold the mold, and the injection material 5 is injected through the injection pipe 4 after the mold is closed. The molding material 5 flows from the top to the bottom into the cavity formed by the first cavity 10 and the second cavity 20, and the molding material 5 is more easily introduced into the cavity due to the gravity.
In one embodiment, as shown in fig. 1 to 8, in the clamped state, the first elastic member 11 is opposed to the second elastic member 21.
Under the mold closing state, the first elastic part 11 and the second elastic part 21 form supports on two sides of the same position of the insert 3, so that the stability of the insert 3 in a mold cavity is improved, and the problem that the insert 3 formed by forming supports on different positions of the first elastic part 11 and the second elastic part 21 is unstable in structure is solved.
For example, at least two first elastic members 11 form a support at the upper side of the insert 3, and at least two second elastic members 21 correspond to the positions of the at least two first elastic members 11 to form a support at the lower side of the insert 3. The at least two first elastic elements 11 and the at least two second elastic elements 21 hold the insert 3 in a stable manner, so that the insert 3 is in the injection-molded position.
