Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a space-saving slider structure. Background Art

[0002] In the field of injection molding, the injection space used to form plastic products is usually surrounded by several mold bodies, usually four mold bodies, which can be called left mold, right mold, front mold and rear mold. The left mold and the right mold are arranged relative to each other and can close the injection space in the circumferential direction, while the front mold and the rear mold are used to close the injection space in the front and rear directions.

[0003] Among them, the left mold and the right mold are fixed on the left slider and the right slider respectively. The left slider moves driven by the inclined left inclined guide column, and the right slider moves driven by the inclined right inclined guide column. The left and right inclined guide columns are relatively arranged and inclined in opposite directions.

[0004] Once the product is formed within the injection molding chamber, the left and right inclined guide pillars move away from the rear mold in the direction of the front and rear molds, driving the left slider away from the front and right molds, and the right slider away from the front and left molds. This releases the constraints on the front and rear molds, allowing the front and rear molds to move away from each other, and the product can be removed. The molds are then reset for the next injection cycle, continuing the continuous production of plastic products.

[0005] In the prior art, each set of mold bodies (including left mold, right mold, front mold and back mold) is equipped with left and right sliders and left and right inclined guide pillars, such as Figure 1 As shown, it is called a slider structure. Multiple slider structures can be arranged in sequence to form a group of slider structures, such as Figure 2 As shown, both sides of all slider structures are provided with shovel bases, which are used to lock the slider after mold closing to prevent the slider from being pushed open by the injection pressure and causing flash on the parting surface of the slider.

[0006] It can be seen that Figure 2 In the set of slider structures shown, each slider is provided with a guide post arranged in an inclined shape. Because the guide post is arranged in an inclined shape, it will be arranged in the direction of the slider structure ( Figure 2 The slider structures occupy a large space in the left and right directions, which makes the overall size larger when multiple slider structures are arranged in sequence, thereby increasing the size of the injection molding equipment. Utility Model Content

[0007] In view of the problem that the slider structure of the injection mold in the prior art is arranged in a large size, the purpose of the present invention is to provide a space-saving slider structure so as to at least partially solve the above problem.

[0008] In order to achieve the above purpose, the technical solution of the utility model is:

[0009] A space-saving slider structure includes several slider pairs, wherein the slider pairs include a left slider and a right slider arranged opposite to each other, and also include a left oblique guide column, a right oblique guide column and at least one left connecting block and a right connecting block; each left slider is fixed to the left connecting block, and each right slider is fixed to the right connecting block; the left oblique guide column is movably inserted in a guide hole opened on one of the left sliders, and the right oblique guide column is movably inserted in a guide hole opened on one of the right sliders; the left oblique guide column and the right oblique guide column are both arranged in an inclined shape and in opposite directions, so that when the left oblique guide column and the right oblique guide column move away from the slider pair, that is, when the mold is separated, the left slider and the right slider move to the left and right respectively.

[0010] In some preferred embodiments, a shovel base is further included, which is used to lock the slider pair when the mold is closed to prevent the slider pair from being stretched apart by the injection pressure.

[0011] In some preferred embodiments, the shovel base is provided between each two adjacent pairs of the sliders.

[0012] In some preferred embodiments, interconnected cooling channels are provided between the left slider and the left connecting block, and between the right slider and the right connecting block.

[0013] In some preferred embodiments, a left water inlet channel and a left water outlet channel are provided in the left connecting block, a left water inlet connected to the left water inlet channel and a left water outlet connected to the left water outlet channel are provided on the left connecting block, and both ends of the cooling channel in each left slider are respectively connected to the left water inlet channel and the left water outlet channel;

[0014] A right water inlet channel and a right water outlet channel are provided in the right connecting block. A right water inlet connected to the right water inlet channel and a right water outlet connected to the right water outlet channel are provided on the right connecting block. Both ends of the cooling channel in each right slider are respectively connected to the right water inlet channel and the right water outlet channel.

[0015] In some preferred embodiments, there are two left connecting blocks and they are arranged relatively spaced apart, and the two left connecting blocks are respectively provided with the left water inlet channel and the left water outlet channel; there are two right connecting blocks and they are arranged relatively spaced apart, and the two right connecting blocks are respectively provided with the right water inlet channel and the right water outlet channel.

[0016] In some preferred embodiments, there are more than two left oblique guide pillars and / or right oblique guide pillars, and they are arranged in sequence and spaced apart.

[0017] In some preferred embodiments, the left oblique guide post cooperates with the left slider at the outermost side, and the right oblique guide post cooperates with the right slider at the outermost side.

[0018] In some preferred embodiments, the left oblique guide column and the right oblique guide column have the same inclination angle.

[0019] By adopting the above technical solution, the beneficial effect of the utility model is that: due to the setting of the left connecting block and the right connecting block, each left slider can be uniformly fixed on the left connecting block, and each right slider can be uniformly fixed on the right connecting block, so that it is only necessary to slide and arrange the guide column in a single left slider and a single right slider, and the other left sliders and right sliders do not need to be provided with guide columns and can also follow the synchronous movement, so that the size of the other left sliders and right sliders can be reduced, and then the arrangement size of the entire slider structure can be reduced.

[0034] Embodiment

[0035] A space-saving slider structure, as shown in Figure 3-6 , comprising a plurality of slider pairs arranged in sequence along a first direction, the first direction refers to Figure 3 the left and right directions, each slider pair comprises a left slider 1 and a right slider 2 arranged opposite to each other along the first direction, and each left slider 1 and each right slider 2 is generally in a working surface parallel to the first direction when in use. The opposite side of the left slider 1 and the right slider 2 is used to fix the left mold and the right mold, and the left mold and the right mold can be fixed when they are close to each other, so as to form an injection molding space between the four. For the convenience of understanding, in this embodiment, the relative arrangement direction of the left mold and the right mold is called the left-right direction, and the relative arrangement direction of the front mold and the rear mold is called the up-down direction.

[0036] It also includes a left connecting block 3, a right connecting block 4, a left inclined guide pillar 5, a right inclined guide pillar 6 and a shovel base 7.

[0037] The left connecting block 3 is long strip-shaped, and the length direction thereof is parallel to the first direction. The left connecting block 3 is arranged on the lower side of the left slider 1, and each left slider 1 is fixedly connected with the left connecting block 3 through a screw. Similarly, the right connecting block 4 is long strip-shaped, and the length direction thereof is also parallel to the first direction. The right connecting block 4 is arranged on the lower side of the right slider 2, and each right slider 2 is fixedly connected with the right connecting block 4 through a screw.

[0038] The left inclined guide pillar 5 and the right inclined guide pillar 6 are arranged in a plane perpendicular to the working surface, and the plane is also parallel to the first direction. In addition, the left inclined guide pillar 5 and the right inclined guide pillar 6 are arranged in an inclined manner relative to the working surface, and the inclined directions of the left inclined guide pillar 5 and the right inclined guide pillar 6 are opposite. The left inclined guide pillar 5 is inclined to the left from top to bottom, and the right inclined guide pillar 6 is inclined to the right from top to bottom.

[0039] A guide hole for cooperating with the left inclined guide pillar 5 is arranged on the leftmost left slider 1, as shown in FIG. 2. Figure 7-9 A guide hole for cooperating with the right inclined guide pillar 6 is arranged on the rightmost right slider 2, and the diameter of the guide hole is slightly larger than the diameter of the corresponding guide pillar. In this way, when the left inclined guide pillar 5 moves upward and away from the working surface where the slider pair is located, each left slider 1 fixedly connected through the left connecting block 3 simultaneously moves along a direction parallel to the left inclined guide pillar 5, and then moves away from the right slider 2. Correspondingly, when the right inclined guide pillar 6 moves upward and away from the working surface where the slider pair is located, each right slider 2 fixedly connected through the right connecting block 4 simultaneously moves along a direction parallel to the right inclined guide pillar 6, and then moves away from the left slider 1.

[0040] The shank base 7 is fixedly installed, and is used to lock the slider pair during mold clamping, so as to prevent the slider pair from being separated by injection pressure.

[0041] Generally, the left inclined guide pillar 5 is fixed on the left base 8, and an external driving mechanism (a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or other types of devices capable of providing linear motion effect) drives the left base 8 to move the left inclined guide pillar 5. Generally, the right side surface of the left base 8 is provided with a left inclined guide surface for guiding the movement of the left slider 1. Similarly, the right inclined guide pillar 6 is fixed on the right base 9, and an external driving mechanism (a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or other types of devices capable of providing linear motion effect) drives the right base 9 to move the right inclined guide pillar 6. At the same time, the left side surface of the right base 9 is also provided with a right inclined guide surface for guiding the movement of the right slider 2.

[0042] Generally, the inclination angles of the left inclined guide pillar 5 and the right inclined guide pillar 6 are the same. In this way, when the left inclined guide pillar 5 and the right inclined guide pillar 6 move upward by the same distance, each left slider 1 and each right slider 2 have the same movement amount, thereby facilitating control.

[0043] It is easy to understand that the left and right sliders 1 and 2 are typically of a certain length, so that multiple mold bodies can be arranged along their length, thereby improving injection molding efficiency. Accordingly, two (or more) left oblique guide pillars 5 (including the left base 8 fixedly connected thereto) are provided and spaced apart along the length of the left slider 1, and two (or more) right oblique guide pillars 6 (including the right base 9 fixedly connected thereto) are provided and spaced apart along the length of the right slider 2.

[0044] It is understandable that in order to speed up the cooling and forming of the product, each left slider 1 is provided with a cooling channel for the cooling medium to flow therein. Accordingly, the left connecting block 3 is provided with a cooling channel for delivering the cooling medium to each left slider 1 and for receiving the cooling medium from each left slider 1. Specifically, the cooling channel in the left connecting block 3 includes a left water inlet channel and a left water outlet channel. The left connecting block 3 is provided with a left water inlet connected to the left water inlet channel and a left water outlet connected to the left water outlet channel. The two ends of the cooling channel in each left slider 1 are respectively connected to the left water inlet channel and the left water outlet channel provided in the left connecting block 3, so that the cooling medium can circulate in each left slider 1 through the left connecting block 3. Figure 6 As shown, it can be seen that the cooling channel inside the left slider 1 has two ports formed on its bottom surface, and these two ports are respectively used to communicate with the left water inlet channel and the left water outlet channel provided in the left connecting block 3. Figure 9 As shown, the cooling channel of the left slider 1 is formed with a plurality of outlets on its right end surface, and these outlets are respectively used to provide cooling medium to the left mold.

[0045] Similarly, each right slider 2 is provided with a cooling channel for the cooling medium to flow therein, and the right connecting block 4 is also provided with a cooling channel for transporting the cooling medium to each right slider 2 and for receiving the cooling medium from each right slider 2. Specifically, the cooling channel in the right connecting block 4 includes a right water inlet channel and a right water outlet channel. The right connecting block 4 is provided with a right water inlet connected to the right water inlet channel and a right water outlet connected to the right water outlet channel. The two ends of the cooling channel in each right slider 2 are respectively connected to the right water inlet channel and the right water outlet channel provided in the right connecting block 4, so that the cooling medium can circulate in each right slider 2 through the right connecting block 4.

[0046] It is easy to understand that there can also be two left connection blocks 3 and two right connection blocks 4.

[0047] The two left connecting blocks 3 are arranged in parallel and relatively spaced apart, and are spaced apart along the length direction of the left slider 1. The two ends of each left slider 1 in the length direction are respectively fixed to the two left connecting blocks 3. At the same time, one of the left connecting blocks 3 is provided with only a left water inlet channel, and the other left connecting block 3 is provided with only a left water outlet channel.

[0048] Similarly, the two right connecting blocks 4 are also arranged in parallel and relatively spaced apart, and are spaced apart along the length direction of the right slider 2. The two ends of each right slider 2 in the length direction are respectively fixed to the two right connecting blocks 4. At the same time, one of the right connecting blocks 4 is configured to have only a right water inlet channel, and the other right connecting block 4 is configured to have only a right water outlet channel.

[0049] This arrangement allows the two ends of the cooling channel in the left slider 1 to be spaced apart along its length, thereby ensuring that the cooling medium flows through the left slider 1 over the largest possible area while also reducing the overall size and weight of the left connecting block 3. The same applies to the right slider 2 and right connecting block 4.

[0050] Typically, each left slider 1 and the left connecting block 3, and each right slider 2 and the right connecting block 4 are positioned by a key 10 or a positioning pin, and the key 10 or the positioning pin can also be used to transmit force, such as Figure 5 shown.

[0051] It is easy to understand that more left connecting blocks 3 and right connecting blocks 4 can be arranged. One left connecting block 3 can be provided with a left water inlet channel, and another left connecting block 3 can be provided with a left water outlet channel. Correspondingly, one right connecting block 4 can be provided with a right water inlet channel, and another right connecting block 4 can be provided with a right water outlet channel.

[0052] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
