Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a telescopic mold storage mechanism. Background Art

[0002] In order to save mold space and facilitate mold management, the upper and lower molds should be matched and stored neatly and orderly after use. In order to avoid mold parts (such as springs, rubber, etc.) from failure due to long-term pressure or damage to the mold edge, the upper mold cannot be directly pressed on the lower mold for a long time, but a mold support device needs to be set between the upper and lower molds.

[0003] There are three commonly used mold support devices at present. The first is a storage block support device, which manually places high-strength steel materials on the lower mold to support the upper mold and ensure that the upper mold is suspended in the non-working state; the second is a polyurethane support device, which supports the upper mold through polyurethane to ensure that the upper mold is suspended in the non-working state; the third is a nitrogen spring support device, which uses the high-pressure gas inside the cylinder to provide force for the plunger to support the upper mold and ensure that the upper mold is suspended in the non-working state. However, the above three mold support devices have the following different problems:

[0004] 1. Storage block support device: When the storage blocks are placed manually, it is impossible to ensure simultaneous placement and retrieval, which can easily cause damage to the mold and pose certain safety risks.

[0005] 2. Polyurethane support device: The support height is small and cannot meet the storage requirements of molds with large storage heights such as large wedges. The support force is small and cannot meet the requirements of multi-layer storage.

[0006] 3. Nitrogen spring support device: The purchase cost of nitrogen spring is high, which increases the development cost of the mold, and the nitrogen spring contains high-pressure gas, which poses a safety hazard. Utility Model Content

[0007] In view of this, the utility model provides a telescopic mold storage mechanism, aiming to solve the above-mentioned deficiencies of the existing supporting device.

[0008] To achieve the above purpose, the technical solution of the utility model is as follows:

[0009] A telescopic mold storage mechanism comprises a lower mold, an upper mold and a mold supporting device arranged between the lower mold and the upper mold, characterized in that: the mold supporting device comprises a mounting base, a force supporting component connected to the mounting base in a horizontal direction and a driving device for driving the force supporting component to slide in the horizontal direction, the mounting base is fixedly assembled on the upper end of the lower mold; a bearing column is provided at the lower end of the upper mold at a position corresponding to the mounting base, the bearing column extends downward along the thickness direction of the upper mold, and under the driving action of the driving device, the force supporting component can move and stop directly below the bearing column.

[0010] With the above structure, before the mold is in a working state, the driving device drives the force-bearing support component to slide linearly, so that the force-bearing support component slides out from under the bearing column, allowing the force-bearing support component to avoid the bearing column and not affecting the opening and closing of the lower mold and the upper mold; before the mold is in a non-working state, the driving device drives the force-bearing support component to slide linearly, so that the force-bearing support component slides to just under the bearing column, so that the bearing column is supported on the force-bearing support component, so that the lower mold and the upper mold are not in direct contact.

[0011] As a preference, the number of the mold support devices is four, which are arranged at the four corners of the lower mold. With the above structure, the four sets of mold support devices in a rectangular distribution are arranged at the four corners, which can more stably support the upper mold.

[0012] Preferably, a guide rail is fixedly mounted on the mounting base, a slider adapted to the rail is slidably mounted inside the rail, and the force-bearing support component is vertically arranged on the slider. With the above structure, the slider is slidably mounted inside the rail, so that the force-bearing support component can be driven by the slider to move along the length direction of the rail.

[0013] Preferably, the slider is provided with a mounting groove; the force-bearing support assembly includes a support column and a support seat fixedly installed on the top of the support column, and the support column is fixedly sleeved in the mounting groove. With the above structure, the slider is provided with a mounting groove, which is convenient for positioning the support column during assembly. During installation, the support column is inserted into the mounting groove and then fixed, which is convenient for assembly. The setting of the support seat can increase the contact area between the load-bearing column and the force-bearing support assembly, making the support of the force-bearing support assembly more stable.

[0014] As a preference: the top of the support seat is provided with a plurality of groups of positioning protrusions, and the bottom of the bearing column is provided with positioning holes adapted to the positioning protrusions. With the above structure, when the bearing column is pressed on the upper end surface of the support seat, the positioning protrusions are all in the positioning holes, which can prevent the upper mold from being pushed by the horizontal thrust, thereby increasing the firmness between the upper mold and the lower mold.

[0015] Preferably, the driving device is a cylinder, which includes a cylinder body fixedly mounted on a mounting base and a telescopic rod connected to the end of the slider. With the above structure, the linear motion of the telescopic rod further drives the slider to perform linear motion.

[0016] Preferably, the cylinder body is fixedly mounted on the mounting base via two sets of L-shaped bracket plates.

[0017] As a preferred embodiment, a protective shell is installed outside the cylinder body. The above structure can prevent the cylinder body from being damaged by external collisions, and has a certain protective effect.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] Before the mold is in working state, the cylinder drives the force supporting assembly to slide out from under the bearing column, so that when the lower mold and the upper mold are in closed state, there is a certain gap between the lower end surface of the upper mold and the force supporting assembly in the height direction, and they will not contact each other, so it will not affect the normal opening and closing of the lower mold and the upper mold; before the mold is in non-working state, the cylinder drives the force supporting assembly to slide to under the bearing column, so that the bearing column can press on the force supporting assembly, so that the mold support device is supported between the lower mold and the upper mold, and the lower mold and the upper mold will not directly contact each other, and there is a certain interval, so as to avoid failure of mold parts due to long-term pressure or damage to the mold cutting edge.

[0025] The utility model is further described below in conjunction with embodiments and drawings.

[0026] like Figure 1 , Figure 2 and Figure 4As shown, a telescopic mold storage mechanism includes a lower mold a1, an upper mold a2, and a mold support device A assembled between the lower mold a1 and the upper mold a2. The mold support device A is arranged between the lower mold a1 and the upper mold a2 in a number greater than one group to maintain the balance of the lower mold a1 and the upper mold a2. In this embodiment, the number of mold support devices A is four groups, and they are arranged at the four corners of the lower mold a1 respectively, so that the support device A can support the upper mold a2 more stably. The support device A includes a mounting base 1 fixedly mounted on the upper end surface of the lower mold a1 and a force-bearing support component 2 connected to the mounting base 1 in a horizontal sliding direction, and the force-bearing support component 2 is driven by a driving device 4 to perform a linear sliding in the horizontal direction. A bearing column 3 is fixedly arranged on the lower end surface of the upper mold a2 at a position corresponding to the mounting base 1, and the bearing column 3 corresponds to the support device A one-to-one. The bearing column 3 extends vertically downward along the thickness direction of the upper mold a2, and the cross-section of the bearing column 3 is rectangular. Under the driving action of the driving device 4, the force-bearing support component 2 can move and stop just below the bearing column 3. After the force-bearing support component 2 moves out from just below the bearing column 3, the force-bearing support component 2 does not contact the upper mold a2, and the opening and closing of the lower mold a1 and the upper mold a2 are not affected.

[0027] Based on the above design, before the mold is in the working state, the driving device 4 drives the force-bearing support component 2 to slide out from under the bearing column 3, so that the lower mold a1 and the upper mold a2 are in the closed state, and the lower end surface of the upper mold a2 and the force-bearing support component 2 have a certain gap in the height direction, and will not contact each other, so it does not affect the normal opening and closing of the lower mold a1 and the upper mold a2; before the mold is in the non-working state, the upper mold a2 is first controlled to rise vertically, and then the driving device 4 drives the force-bearing support component 2 to slide to under the bearing column 3, and finally the upper mold a2 is vertically lowered, so that the bearing column 3 is pressed on the top of the force-bearing support component 2, and the lower mold a1 is pressed on the mold support device A, the lower mold a1 and the upper mold a2 will not be in direct contact, and there is a certain interval, so as to avoid the failure of mold parts due to long-term pressure or damage to the mold cutting edge.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a guide rail 5 is fixedly mounted on the mounting base 1, and a slider 6 adapted thereto is slidably mounted inside the rail 5. The slider 6 can slide along the length direction of the rail 5, and the force-bearing support assembly 2 is vertically arranged on the slider 6. A circular mounting groove 61 is provided on the slider 6. The force-bearing support assembly 2 includes a support column 22 of a cylindrical structure and a support seat 21 fixedly mounted on the top of the support column 22. During installation, the support column 22 is inserted into the mounting groove 61 and then fixed, which is convenient for assembly.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, the support seat 21 has a rectangular cross section and cooperates with the bearing column 3. The support seat 21 can directly support the bearing column 3. A plurality of groups of positioning protrusions 211 are distributed on the top of the support seat 21, and a positioning hole 31 adapted to the positioning protrusions 211 is distributed on the bottom of the bearing column 3. In this embodiment, the number of the positioning protrusions 211 and the positioning holes 31 are both four groups, and they correspond to each other. Based on the above design, when the bearing column 3 is pressed on the upper end surface of the support seat 21, the positioning protrusions 211 are all in the positioning holes 31, which can prevent the horizontal thrust from pushing the upper mold a2, and increase the reliability between the upper mold a2 and the lower mold a1.

[0030] like Figure 2 and Figure 3 As shown, the driving device 4 in this embodiment is a cylinder 41, and the cylinder 41 includes a cylinder body 411 fixedly mounted on the mounting base 1 and a telescopic rod 412 connected to the end of the slider 6. The cylinder body 411 is fixedly mounted on the mounting base 1 through two sets of L-shaped bracket plates 7, and the two sets of bracket plates 7 are respectively arranged at the front and rear ends of the cylinder body 411. A protective shell 8 is installed outside the cylinder body 411 to prevent external collisions, thereby avoiding failure of the cylinder 41 caused by air leakage of the cylinder body 411, thereby improving safety. A card connector 413 is fixedly mounted on the outer end of the telescopic rod 412, and a card interface 62 is provided on the end of the slider 6 close to the cylinder body 411. The card connector 413 and the card interface 62 are adapted to each other, and the card connector 413 can slide from the top of the card interface 62 and be embedded in the card interface 62, thereby realizing the fixed connection between the telescopic rod 412 and the slider 6.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
